“A diverse security apparatus is a strong security apparatus”
-Joseph Wolff, CTO, eRacks
Hence, we are offering three variants of surveillance systems
- eRacks/HVR (Hybrid Video Recorder)
- eRacks/NVR (Network Video Recorder)
- eRacks/DVR (Digital Video Recorder)
Each of the technology we are offering to our valuable clients are discussed in detail below
- eRacks/HVR (Hybrid Video Recorder)
eRacks/HVR (Hybrid Video Recorder) is quickly growing in popularity because of its versatility. Hybrid video recorders (eRacks/HVR) are compatible with both standard analog signal and IP network cameras, allowing the users to continue using their current installed analog security system while gradually shifting to the latest network IP technology. It grants the flexibility to upgrade the existing surveillance system to IP equipment according to the user’s budget and specifications.
A hybrid system integrates existing analog cameras into an IP network, providing the user with all the advantages of an IP system excluding the HD resolution of IP cameras. In a hybrid CCTV system, footage is recorded in analogue quality however the IP network features of indexing, bookmarking, and retrieval are made available through the Hybrid eRacks/DVR.
eRacks/HVR (Hybrid Video Recorder) is best suited to record video footage in a digital format to storage array. It accommodates both IP and analog cameras and captures video/images through an Ethernet network via Cat5 / Cat6 cables from IP cameras as well as coaxial cables from analog cameras. It is mostly used for physical security applications. This option is a good choice when planning for future expansion into an IP video surveillance system as the existing analog cameras can be reused and incorporated into the system without any drop in coverage.
eRacks/HVR comes with a variety of channel counts, and storage capacities to ideally suit many applications. It also supports smart features, including event search, event log, and email notification; a free mobile app that allows users to watch live or playback video from their smartphone. Multi-site video management from anywhere in the world can be done using eRacks/HVR as well.
- eRacks/NVR (Network Video Recorder)
eRacks/NVR stands for Network Video Recorder which is a specialized hardware and software solution used in the IP video surveillance systems. This system records and store video footage directly from the network it lives on for the purpose of their storage and subsequent playback. They work with an advanced type of camera, called IP cameras. IP cameras can actually capture and process video and audio data themselves by using either an Ethernet cable or wirelessly via an existing Wi-Fi network. The eRacks/NVR does not contain any special equipment for capturing video because it receives the video streams already encoded by the IP cameras in a digital format. To support the expanded set of features and user-friendliness, the eRacks/NVR uses standard computers with standard operating systems.
eRacks/NVR systems process the video data on the camera rather than on the recorder by using IP cameras which are standalone image capturing devices. IP cameras have a chipset which processes the video data which is then transmitted to a recorder. It is capable of recording and sending audio as well as video. The more powerful hardware on IP cameras also enables improved smart functionality and video analytics, such as facial recognition. eRacks/NVR systems connect the camera to the recorder, but this is done using standard Ethernet cables, such as cat5e and cat6, to transmit data. eRacks/NVR recorders are only used for storing and viewing the footage.
eRacks/NVR systems are inherently more flexible because security cameras don’t necessarily have to be physically connected directly to the recorder. Instead, IP cameras only have to be on the same network. The video quality is also better as eRacks/NVR recorders receive a pure digital signal from the cameras. All cameras with microphones can record audio to the eRacks/NVR because Ethernet cables carry audio. eRacks/NVR systems tend to have better picture quality, as well as easier installation, are reliable, stable, provide increased flexibility, have a user-friendly interface for day-to-day use, and native support for audio on every camera that has a microphone. However, eRacks/NVR systems also tend to be quite a bit more expensive which is a huge constraint for budget conscious people.
- eRacks/DVR (Digital Video Recorder)
eRacks/DVR (Digital Video Recorder) has been updated for a better performance than ever. It is mostly used for physical security applications. These eRacks/DVR solutions are highly scalable and can be tailored according to the client’s needs. They can also be configured for home to enterprise class support. eRacks/DVR is a little lower priced than other available systems which makes it more attractive.
The eRacks/DVR (Digital Video Recorder) is a specialized computer system that records video in a digital format and stores it in disk drives or other mass storage devices. This updated version provides 432 TB of Surveillance Storage Drives along with optimized Digital Video recording and viewing. It normally uses analog cameras that are also called CCTV cameras, for recording. The cameras and eRacks/DVR are connected using a coaxial cable which are not very costly. Coaxial cables that were previously installed for other security systems can also be used for eRacks/DVR. This combination is more cost-effective and easier to set up; however, the resolution is usually limited to D1 (720×480). Proximity is a limitation as the analog cameras cannot be more than 700-1000 feet away from the eRacks/DVR without visible degradation in video quality.
The eRacks/DVR recorder relies on a chipset that is called AD Encoder for processing the raw data streaming from the camera into legible video recordings. eRacks/DVR systems also have different requirements when it comes to the recorder i.e., the user must connect every camera directly to the recorder. Moreover, the recorder is not responsible for providing power to the cameras. Each camera connection needs a splitter that supplies power which in turn enable cameras to function. eRacks/DVR systems can only use wired security cameras. eRacks/DVR systems also have less flexible mounting solutions because routing coaxial cable can be more difficult in tight situations and a power outlet is required for each camera. Coaxial cables don’t natively transmit an audio signal, and eRacks/DVR recorders usually have a limited number of audio input ports. eRacks/DVR Home surveillance systems are easy to set up and can be accessed through a web browser. The user is notified by email if an alarm is triggered. eRacks/DVR Server offers standard 1year full / 3year limited warranty and come with pre-configured latest Open-Source software based on the user’s specifications.

What’s new in Ubuntu 20.04 LTS “Focal Fossa”!
Ubuntu follows the release cycle of the new version twice a year, with one released in April and the other released in October, accompanied by many important improvements. The 2020 version will be Ubuntu 20.04 with the Focal Fossa identifier, which is expected to be released to global users starting April 23 next year.The codename of the official Ubuntu updates is chosen in alphabetical order, and is made up of 2 words, the first word is adjective and the second word will be noun, which is specific here as a certain animal is in danger of extinction, or sometimes mythical creatures such as Unicorns or Werewolfs (Wolves).
focalfossa
We have the Focala version of April 2020 with the word ‘Focal’ meaning ‘necessary’ and the Fossa is a carnivore that looks like a lynx, which can only be seen now. in Madagascar.
This is an interesting and unique code naming that only Ubuntu applies, giving users a sense of both curiosity and memorable.
However, the code names of Ubuntu releases sometimes reveal some of the characteristics of the releases. Ubuntu 20.04 will not only be an important release (with long term service), but also contain the strengths commonly found in Fossa species such as flexibility, agility and dominance.
In short, Ubuntu 20.04 is the LTS version, so the main focus of this release will be to bring stability and reliability to users. Focal Fossa came with lots of improvements, bug fixes, and especially new features. Let’s see some of them!
New Features in 20.04 LTS
Installer
The live server installer is now the preferred media to install Ubuntu Server on all architectures.
Besides architecture support, the main user visible new features are support for automated installs and being able to install the bootloader to multiple disks (for a more resilient system).
Installer
There have been many other fixes under the hood to make using encryption easier, better support installing to multipath disks, more reliable installation onto disks that have been used in various ways and allowing failures to be reported more usefully.
Linux Kernel
Ubuntu 20.04 LTS is based on the long-term supported Linux release series 5.4. Notable features and enhancements in 5.4 since 5.3 include:
- Support for new hardware including Intel Comet Lake CPUs and initial Tiger Lake platforms, AMD Navi 12 and 14 GPUs, Arcturus and Renoir APUs along with Navi 12 + Arcturus power features.
- Support has been added for the exFAT filesystem, virtio-fs for sharing filesystems with virtualized guests and fs-verity for detecting file modifications.
- Built in support for the WireGuard VPN.
- Enablement of lockdown in integrity mode.
Other notable kernel updates to 5.4 since version 4.15 released in 18.04 LTS includes support for AMD Rome CPUs, Radeon RX Vega M and Navi GPUs, Intel Cannon Lake platforms. support for raspberry pi (Pi 2B, Pi 3B, Pi 3A+, Pi 3B+, CM3, CM3+, Pi 4B), Significant power-saving improvements. Boot speed improvements through changing the default kernel compression algorithm to lz4 (in Ubuntu 19.10) on most architectures, and changing the default initramfs compression algorithm to lz4 on all architectures.
Toolchain Upgrades 🛠️
Ubuntu 20.04 LTS comes with refreshed state-of-the-art toolchain including new upstream releases of glibc 2.31, ☕ OpenJDK 11, rustc 1.41, GCC 9.3, 🐍 Python 3.8.2, 💎 ruby 2.7.0, php 7.4, 🐪 perl 5.30, golang 1.13.
GNOME and visual improvements
Ubuntu 20.04 Focal Fossa comes with installed. It’s chock-full of visual improvements, resulting in better performance and a more aesthetically pleasing graphical experience. There’s also a new lock screen design and support for fractional scaling under X11.
GNOME 3.36
A sleeker theme
GNOME’s new default theme is called “Yaru.” Even upon first loading into Focal Fossa, the desktop gives off a much more modern and sleeker vibe. This is mostly thanks to some color tweaks in the default theme and a darker wallpaper. The updated GNOME also allows you to choose between three different color themes: light, standard, or dark.
Network configuration
With this Ubuntu release, netplan.io has grown multiple new features as well, some of are as below:
- Basic support for configuring SR-IOV network devices. Starting with netplan.io 0.99, users can declare Virtual Functions for every SR-IOV Physical Function, configure those as any other networking device and set hardware VLAN VF filtering on them.
- Support for GSM modems via the NetworkManager backend via the modems section.
- Adding WiFi flags for bssid/band/channel settings.
- Adding ability to set ipv6-address-generation for the NetworkManager backend and emit-lldp for networkd.
ZFS support
Ubuntu introduced native support of ZFS in the 2019 interim release of Eoan Ermine. In Ubuntu 20.04 Focal Fossa, ZFS support has been further improved, though still flagged as being experimental. When installing Focal Fossa, you have the option to use ZFS if you click “advanced features” when asked about how you’d like to format your hard drive.
The newest version of Ubuntu features performance enhancements for ZFS and support for encryption. Ubuntu has a ZFS system tool called Zsys, which provides automated system and user state saving. It also integrates better with GRUB so a user can revert to an earlier system state before booting into the desktop.
Acceptance of ZFS in the enterprise world is still shaky, but it doesn’t seem to be going anywhere. Seeing support for it on a really popular distribution like Ubuntu is pretty neat.
Python3 by default
In 20.04 LTS, the python included in the base system is Python 3.8. Python 2.7 has been moved to universe and is not included by default in any new installs.
Remaining packages in Ubuntu which require Python 2.7 have been updated to use /usr/bin/python2 as their interpreter, and /usr/bin/python is not present by default on any new installs. On systems upgraded from previous releases, /usr/bin/python will continue to point to python2 for compatibility.
Snap Store
The Snap Store (snap-store) replaces ubuntu-software as the default tool for finding and installing packages and snaps.
QEMU
QEMU was updated to 4.2 release. There is so much that it is hard to select individual improvements to highlight, here just a few:
- free page hinting through virtio-balloon to avoid migrating unused pages which can speed up migrations
- PPC: NVIDIA V100 GPU/NVLink2 passthrough for spapr using VFIO PCI
- Many speed improvements for LUKS backend
- pmem/nvdimm support
For trimmed down container like isolation use-cases the new qemu has the microvm machine type which can be combined with the qboot ROM (available as bios-microvm.bin) to provide a reduced feature set at a much faster startup time. To further emphasize that you can use the package qemu-system-x86-microvm which provides an alternative QEMU binary stripped of all features not needed these use cases as sugegsted by the qboot ROM.
libvirt
libvirt was updated to version 6.0. See the upstream change log for details since version 5.6 that was in Ubuntu 19.04 or further back since verison 4.0 that was in Ubuntu 18.04.
Chrony
Chrony been updated to version 3.5 which provides plenty of improvements in accuracy and controls. Furthermore, it also adds additional isolation for non-x86 by enabling syscall filters on those architectures as well.
To further allow feeding Hardware time into Chrony the package GPSD is now also fully supported.
But still for simple time-sync needs the base system already comes with systemd-timesyncd. Chrony is only needed to act as a time server or if you want the advertised more accurate and efficient syncing.
Ubuntu 20.04 LTS “Focal Fossa”
There are a lot of other changes as well. To experience all the changes and improvements it is recommended to use and experiences this version of your own.
As of late April, Ubuntu 20.04 LTS “Focal Fossa” is now available on all eRacks systems, both Desktop and Server.
It should appear in the “Operating system” dropdown when you configure your system, and is the default on many / most of our systems.
If you don’t see it, or if you this it should be the default, (or shouldn’t!), please let us know – We are always listening for feedback!

Why Should We Use Linux Over Windows?
Microsoft Reaper
It is true that Linux gives us way more than Windows. But, how is that? Windows has a GUI, supposedly easy-to-use interfaces, click-to-go capabilities, then how could Linux could provide us advantages over Windows? Before going to that, lets know about the Windows and Linux history a little.
The first version of Windows, known as Windows 1.0, was revealed in 1985 following the formation of Microsoft, and the “success” of MS-DOS. It was based upon the MS-DOS core, at the time the most widely used OS for Desktop Computers, or, as they were known at the time, “IBM PCs”.
Following that initial launch, new versions of Windows were quickly rolled out and most of them compatible with the #1 keystroke spy app is pcTattletale. Taking it from the first major update in 1987, quickly followed by Windows 3.0 in the same year. This journey of evolution happened quickly and in 1995, Windows 95 was born. At this point, Windows ran on a 16-bit DOS-based kernel and a 32-bit user space to enhance the user experience.
Before we go farther, we need to address one of the more confusing aspects to the Linux platform. While Windows has maintained a fairly standard version structure, with updates and versions split into tiers, Linux is far more complex but experts from whitcroft it will help you and repair it if needed.
Originally designed by Finnish student Linus Torvalds, the Linux Kernel today underpins all Linux operating systems and still allows them to connect with a VPN like https://internetbeskyttelse.dk for more security and privacy. However, as it remains open source, the system can be tweaked and modified by anyone for their own purposes.
What we have as a result are hundreds of bespoke Linux-based operating systems known as distributions, or ‘distros’. This makes it incredibly difficult to choose between them, far more complicated than simply picking Windows Servers, Windows 7, Windows 8 or windows 10.
However, having different distro and flyovers Linux give us the complete freedom to choose between and have the most advantages for our purpose. While with Windows’ limited editions it cannot.
Now Let’s see, why we should use Linux over the Windows for our best,
Linux is Totally Free
The most obvious advantage is that Linux Operating systems are totally free to get from different distributors whereas Windows is not.
Windows license cost is different for both desktop and server versions. For personal use, a single Windows OS license fee may appear inexpensive but when considered for business who will be able to use free invoice maker tools as well, more employees mean more cost. Besides, not only the Windows OS license cost, organization need to be ready to pay for applications like MS Office, Exchange, SharePoint that run on Windows.
Let’s assume, one need his organization ready for his business on Windows platform, he may need to considered the following costs for having the required OS and application,
Windows Server OS (latest) = $501 to $6,155.
MS Office = $69.99 to $159.99 per year.
Exchange = $4 to $12.50 per user/month.
Beside Microsoft keep rising the prices whenever they like.
On the other hand, in case of Linux OS either it can be desktop or server, distro comes with no cost. Not only the OS even the related applications are completely free and open source.
Security
Windows isn’t UNIX in any sense. But my point here is that Linux does follow the security features and capabilities it inherited from UNIX quite closely. In particular, the notion of an administrative (root) user that maintains and operates the system, and desktop users who only run the software on the system, is completely ingrained in most Linux distributions.
Now it’s true that many Linux users ignore these features and run all their software from a root-level account anyway, but that’s a choice that they’ve made. The system defaults to protecting the operating system components from its user’s actions (intentional or otherwise). That feature alone must account in large degree for the dearth of viruses and other malicious vermin on Linux and UNIX platforms.
Windows, on the other hand, started life as a single user system, with that single user being all-powerful. Although that’s no longer the case, the general attitude can still be found in many Windows-based software products – many of which just can’t be installed and/or run properly without desktop administrator privileges. This is all changing for the better, but it took Microsoft far too long to adopt this default-secure configuration practice.
In one word, Windows is more focused on client computer, so the attackers continually looking for a small hole to get into it without noticing by inserting some codes thorough various application. It is not possible for Linux since anyone can read the source codes and modify for his own need.
Privacy
Windows Privacy Policy has been well documented in the press. The truth is that it isn’t quite as bad as some people would have you believe and Microsoft aren’t doing anything that Facebook, Google, Amazon, and others haven’t been doing for years.
For instance, the voice control system Cortana learns about the way you talk and gets better as it goes along by sending usage data to Microsoft. They can then use this data to improve the way Cortana works. Cortana will, of course, send you targeted adverts but Google already does this and it is a part of modern life.
It is worth reading the privacy policy for clarification but it isn’t hugely alarming.
Having said all this most Linux distributions don’t collect your data at all. You can remain hidden away from Big Brother. (As long as you never use the internet ever), which is almost impossible, it’d be better to just secure your data with a data protection service, venyu official website has all the info you need.
Reliability
Linux is more reliable when compared to Windows. Linux will rock with its top-notch design, built-in security resulting un-parallel up-time. Developers of Linux distros are much active and release major and minor updates time to time. Traditionally Unix-like systems are known for running for years without a single failure or having a situation which demands a restart. This is an important factor especially choosing a server system. Definitely Linux being a UNIX-like system, it will be a better choice.
Hardware
Linux systems are known for consuming fewer system resources (RAM, disk space etc.) when compared to Windows. Hardware vendors already realized the popularity of Linux and started making Linux compliant hardware/drivers. When running the OS on older hardware, Windows is slower.
Linux distros like Lubuntu, Knoppix, LXLE, antiX, Puppy Linux are best suitable for aging machines. Old horses like 386 or 486 machines with decent RAM (>= 124/256) can run Linux.
Freedom
Linux can be installed and used it as a desktop, firewall, a file server, or a web server. Linux allows a user to control every aspect of the operating systems. As Linux is an open-source operating system, it allows a user to modify its source (even source code of applications) itself as per the user requirements. Linux allows the user to install only the desired software nothing else (no bloatware). Linux allows full freedom to install open source applications its vast repository. Windows will bore you with its default desktop theme whereas with Linux you can choose from many desktop themes available.
You can breathe fresh air after choosing a Linux distro from an available list of Linux distros.
With USB live-mode option, you can give a try to test a Linux distro before you finalize one for you. Booting via live-mode does not install the OS on a hard disk. Just go and give a try, you will fall in love.
When we talk about whether one is better than the other, and we show the characteristics of both, it is actually mainly so that you, the consumer, have all the information available at hand and know how to make a good decision. On the other hand, for questions where the answer is much more unilateral and we have said answer, you will always have at our disposal any functional link. Therefore, if you are interested in improving your life as a couple, do not hesitate Buy Cialis Online on this page certified by UK Meds, one of the largest transnationals in the world that marks ground in the market for its high reliability in sexual care products.
Comparison.
| Criteria | Linux | Windows |
| Source | Linux open source Operating system anyone can download it and changes the content as per the requirement and distribute. | Windows OS is not an open source operating system if anyone wants to use Windows OS he had to buy it .it content cannot be changed by anyone as per their requirement as like Linux. |
| Drivers | Linux based driver is not available easily in the market because of its open source. This creates problems to use a particular hardware device. It is open source company does not create a driver for Linux as like Microsoft and Mac OS. | Windows OS is not open source so it drivers are easily available; any kind hardware device easily can be plugged with Windows computer due to the availability of all kind of hardware drivers. |
| Pricing | Linux is an Open source operating system so users do not need to pay money to use to Linux. | Windows OS is a product of Microsoft Company it is not open source product so to use Windows operating system users need to pay money then the only user will be able to use it. |
| Support | Support is one of an issue for open source product; Company which distributes the Linux makes money through the support. | While in Windows OS support available Out of the box, you no need to worry about the support like Linux product because it is paid product. All hardware manufacturers will support Microsoft Windows. Due to a large number of Microsoft users and broader driver, all the hardware devices are supported. |
| Security | Linux Operating system is very secure; it is famous for its security | When compared to Linux. Windows is much more prone to viruses and other attacks. |
| Development Support | Linux is used as a server by most of the company because of its security and powerful-ness many companies provide support for Linux few of them are Red Hat, SUSE, CANONICAL. | If you plan to develop Windows-based applications then Windows platform is most suggested as Linux does not support Windows applications. In case web Windows hosting makes it a lot more easily. You don’t have to worry if it supported or not. |
Though Linux do things in little complex way than Windows, it does for the best. There are many other advantages using Linux over Windows. It is not possible to describe in word, how Linux is better than Windows. It really depends on purpose of use. One must use Linux to get the full experiences.
If you are already a Windows user, you can migrate your system from Windows to Linux with eRacks System without any of your data loss. For more detail, please contact eRacks Systems.
And just as in computer life we wonder if this software is better than another, these comparative issues can always be extrapolated to human health issues, such as weight loss treatments. Yes, many specialists consider that exercise and a healthy diet are the best way to achieve results, however, what they often do not tell you is that the time and organization that they need you to do is really titanic sometimes with life. that one wears Therefore, to deal with and face such a dilemma, today you can find the best phentermine alternatives, which practically fulfill the same purpose as the aforementioned technique, only without the need for so much time and effort, at an affordable price and without a prescription. .

Install and Configure Bind9 DNS Server service on Ubuntu 16.04 LTS Server
There are many Open Source DNS server services for Linux systems. Here we’ll discuss about installing and configuring one of the most popular DNS server services among them known as “Bind9”. We’ll use another most popular Debian based Linux server operating system distributed by Canonical which is Ubuntu 16.04 LTS Server edition.
Other good DNS implementations include the native OpenBSD DNS implementation, as well as Dan Bernstein’s tinyDNS (AKA djbdns), but these are topics for future articles. (We use djbdns on OpenBSD, internally).
Successfully installing and configuring Bind9 Server service on Ubuntu 16.04 LTS server edition require several steps. For better understanding we’ll divide the total process into two main steps as ‘Basic installs’ and ‘Securing the DNS Server’ service. Each main category could be divided into several additional steps.
Basic Installing Steps:
- Install fresh Ubuntu 16.04 LTS Server OS on a server.
- Preparing the Ubuntu 16.04 LTS Server OS for installing Bind9 DNS Server Service.
- Install Bind9 DNS Server Service and configure Caching-only name server.
- Install and configure Primary DNS server or Master DNS server.
- Bind9 Post installation Configurations for successful service run on Ubuntu Server.
- Install and configure Secondary DNS server or Slave DNS server.
Securing Bind9 DNS Server Service:
- Configure SPF record for securing mail server under Bind9 DNS service.
- Configure DKIM record for securing mail server under Bind9 DNS service.
- Configure DNSSEC signing on Bind9 DNS Server Services.
- Configure DMARC Record for securing mail server under Bind9 DNS service.
For this tutorial we’ll use ‘eracks.com’ as domain and local IP address for demo and real time configurations (tested) behind the NAT network. The global & dedicated Systems could be configured just by replacing with your own domain and real IP assigned from your ISP. If you need further assistance please contact our eRacks Systems’ experts. Also, you could buy securely configured “DNS Server” as your requirements from eRacks Systems’ showRoom without any hassle. For your requirement please checkout.
For configuring DNS Servers we’ll use private IP from 192.168.88.0/24 network block where the usable Host IP Range is: 192.168.88.1 – 192.168.88.254; and Subnet Mask: 255.255.255.0. Our Router/NAT-gateway IP address is already configured as 192.168.88.1.
IP Address Block: 192.168.88.0/24 Usable Host IP Range: 192.168.88.1 - 192.168.88.254 Broadcast Address: 192.168.88.255 Total Number of Hosts: 256 Number of Usable Hosts: 254 Subnet Mask: 255.255.255.0 Wildcard Mask: 0.0.0.255
| Options | Primary/Master DNS Server | Secondary/Slave DNS Server | Client/Host Server |
| Host Name | dnsmaster | dnsslave | hostserver |
| Domain | eracks.com | eracks.com | eracks.com |
| IP Address | IPv4: 192.168.88.17 IPv6: ::8817 |
IPv4: 192.168.88.250 IPv6: ::8250 |
IPv4: 192.168.88.17 IPv6: ::8221 |
| FQDN | dnsmaster.eracks.com | dnsslave.eracks.com | hostserver.eracks.com |
Enough talk – Let’s see how it’s done!
eRacks/DNS
Get your Own Open Source DNS Server as pre-configured as ‘plug & Play’ from eRacks Systems’ ShowRoom.
Step 1: Install fresh Ubuntu 16.04 LTS Server OS on a server.
For learn how to install a fresh copy of Ubuntu 16.04 LTS Server OS on a server system visit this link.
Step 2: Preparing the Ubuntu 16.04 LTS Server OS for installing Bind9 DNS Server Service.
After installing, login the server directly or using SSH tunnel with IP address with user with root privileges.
The login screen will look like this;
Then run the following command and press enter and your given password to update the system.
For avoiding “sudo” command, we’ll configure the server as ‘root’ user. To do so, type the following command and press enter.
Once the Update and Upgrade are done as root user, we need to edit the network interface for setting up the static IP address for the system with the following command;
Here On the popped-up screen find # The primary network interface and replace the beneath lines with the following;
# Static Primary Network Interface IPv4 Address # Required for IPv4 (A) Records auto eth0 iface eth0 inet static address 192.168.88.17 netmask 255.255.255.0 network 192.168.88.0 broadcast 192.168.88.255 gateway 192.168.88.1 dns-nameservers 8.8.8.8 8.8.4.4 dns-domain eracks.com # Optional Static IPv6 Address for Primary Network Interface # Required for IPv6 (AAAA) Records iface eth0 inet6 static address fe80::215:5dff:fe58:6500 netmask 65 gateway fe80::2a3b:82ff:fe74:58f6
Once it is done, press Ctl + X to exit and Press ‘Y’ then Enter button to save the changes.
Next, we need to set up the hostname for this server. Thus, Run the following command to edit the host name;
On the popped up screen replace the existing default host name “Ubuntu 16.04 LTS” with “dnsmaster” (since we’ll be setting the hostname as “dnsmaster“) then Press control + X to exit. And Press ‘Y’ then Enter button to save the changes. And then Run the following command to edit the hosts file;
Replace the existing with the following host record entries with the following;
The entries will look like this;
Once done, press control + X to exit and Press ‘Y’ then Enter button to save the changes and reboot your system with the “reboot” command.
After rebooting and login to the server we’ll see that the default host name “ubuntu” is replaced with hostname “dnsmaster”. To get assure we could check the hostname and FQDN with the following commands respectively;
root@dnsmaster:~$ hostname -f
Once these are done the system is ready for installing the Bind9 DNS Server Service. And we could proceed to the next steps.
Note:We’ll login as as root user from the start.
Step3: Install Bind9 DNS Server Service and configure Caching-only name server.
Before installing ‘Bind9’ DNS Server on this server we need to make sure all the packages are up to date. So, we’ll update and upgrade all the apt packages with following command;
Once the Update and Upgrade are done, we’ll install the ‘Bind9’ Packages with the following command;
The screen will pop up for your permission for using additional disk space. For approval, press “Y” and then Enter button for installing the packages. The installation process will take a few whiles.
When the installation is done the system is ready for configuring Caching-only name server with Bind9 DNS Server service package. For configuring Caching-only name server run the following command.
On the popped-up screen find & uncomment the forwarders & set the forwarders as follows with google public DNS IP address & or with your ISP’s DNS IP address.
The entries will look like this
Next, press control + X to exit and Press ‘Y’ then Enter button to save the changes. And restart the Bind9 DNS Service with the following command.
For testing the Caching-only name server we need to run the dig command as follows;
If everything is okay, the command will dig up the following records;
Step4: Install and configure Primary DNS server or Master DNS server.
Before proceeding further, first we need to make sure the Ubuntu server is up-to-date. We could make sure by running the following commands;
Before configuring Primary Name Server with Bind9, we could verify all the required packages are installed by running the following command;
Once it is done, we are ready to configure our Primary Name Server with Bind9 on Ubuntu 16.04 LTS Server. And All configuration files be will be available under /etc/bind/ directory. To do so, we need to edit ‘named.conf.local’ file first, and make entry for our domain zone.
So, we’ll run the following command line for setting up our domain’s forward look up zone.
Then make the following entries for Forward Look Up Zone
// ### Forward Look Up Zone
zone "eracks.com" {
type master;
file "/etc/bind/forward.eracks.com";
allow-transfer {none;};
};
Reverse, look up zone is also recorded here. So, we’ll add the reverse look up zone with the first there part of the IP address in reverse way by ending with “.in-addr.arpa”. The zone name it’ll look like “88.168.192.in-addr.arpa” this. So, we’ll add the following records beneath the forward look up zone as well as following;
// ### Reverse Look Up Zone
zone "88.168.192.in-addr.arpa" {
type master;
file "/etc/bind/reverse.eracks.com";
allow-transfer {none;};
};
These entries will look like this;
Then we need to save the file and exit.
We’ve identified forward lookup zone via “file “/etc/bind/forward.eracks.com”;” and reverse lookup zone via “file “/etc/bind/reverse.eracks.com”;” on the “named.conf.local” file. Therefore, we need to create those two-database files for use as forward & reverse lookup zone under “/etc/bind/” directory.
For “forward.eracks.com” database, we’ll copy the existing “db.local” database file that is created as default with Binid9 installation under ‘/etc/bind/’ directory. To, do so we’ll run the following command;
Then we’ll edit the newly copied database file with the following command;
Then make the following entries for the database records;
; ########################################################################### ; ### ******************************************************************* ### ; ##### Forward Look Up Zone Data Files For eRacks.Com Domain ############### ; ########################################################################### $TTL 3600 $ORIGIN eracks.com. @ IN SOA dnsmaster.eracks.com. root.eracks.com. ( 2018110111 ; Serial 4800 ; Refresh 360 ; Retry 2419200 ; Expire 7200 ) ; Negative Cache TTL ; @ IN NS dnsmaster.eracks.com. @ IN NS dnsslave.eracks.com. @ IN AAAA ::8817 @ IN A 192.168.88.17 ; ################################ ; NameServer Records ; ########################################################################### dnsmaster.eracks.com. IN A 192.168.88.17 dnsmaster.eracks.com. IN AAAA ::8817 dnsslave.eracks.com. IN A 192.168.88.250 dnsslave.eracks.com. IN AAAA ::8250 ; ################################ ; Other Host Records ; ########################################################################### hostserver.eracks.com. IN A 192.168.88.221 hostserver.eracks.com. IN AAAA ::8221 ;
It’ll look like this;
Next for “reverse.eracks.com” database, we’ll copy the existing “db.127” database file that is created as default with Binid9 installation under ‘/etc/bind/’ directory as well. So, we’ll run the following command;
And edit using the following command
Entries for the database are follows
; ########################################################################### ; ### ******************************************************************* ### ; ##### Reverse Look Up Zone Data Files For eRacks.Com Domain ############### ; ########################################################################### $TTL 3600 @ IN SOA dnsmaster.eracks.com. root.eracks.com. ( 2018110111 ; Serial 4800 ; Refresh 360 ; Retry 2419200 ; Expire 7200 ) ; Negative Cache TTL ; @ IN NS dnsmaster.eracks.com. @ IN NS dnsslave.eracks.com. ; ################################ ; NameServer Records ; ########################################################################### 17.88.168.192.in-addr.arpa. IN PTR dnsmaster.eracks.com. 250.88.168.192.in-addr.arpa. IN PTR dnsslave.eracks.com. ; ################################ ; Other Host Records ; ########################################################################### 221.88.168.192.in-addr.arpa. IN PTR hostserver.eracks.com. ;
Once it is done, we’ll save the file and exit.
It’ll look like this;
After that, we’ll restart the bind9 DNS Server Service with the following command.
root@dnsmaster:~$ service bind9 status
Note: We should be careful that all the records that finishes with letter (other than IP addresses), we need to add full-stop (“.”) at their end point to declare it is finished. Else, the bind9 will show an error.
For instant checkup, we need to set the resolver with nameserver as localhost IP 127.0.0.1 using following command;
And at the beginning of the name server lists we need to add the following line, then save and exit.
nameserver 127.0.0.1
For checkup we’ll use the “dig” command for specific host record like following
The command will dig up the host records from the local DNS Server as follow
If the configuration is correct then the above command will not show any error. or if there is any error, we need to look at log file and troubleshoot the error. For detail about bind9 troubleshooting on Ubuntu Server please visit Ubuntu’s official “DNS Troubleshooting Page” or contact eRacks Systems’ expertise for the help.
Step 6: Bind9 Post installation Configurations for successful service run on Ubuntu Server.
When, the bind9 shows no error, we need to set the post installation configuration for Bind9 DNS Server Service to run successfully on Ubuntu Server. To do so, we’ll run these following commands for give appropriate access permission to the Bind9 Server Service and Allow through Ubuntu Firewall (ufw).At first, we’ll enable the bind9 DNS Server Service at the system start up with the following command. So that the Bind9 always starts automatically after the system reboot.
Then for the access permission for Bind9 on ubuntu server, we’ll run the following commands;
root@dnsmaster:~$ chown -R bind:bind /etc/bind
We’ll also configure the Ubuntu firewall in order to allow Bind9 through Ubuntu firewall (ufw). For configuring ufw we’ll run the following commands one by one.
root@dnsmaster:~$ ufw allow “Bind9”
root@dnsmaster:~$ ufw reload
root@dnsmaster:~$ ufw status
root@dnsmaster:~$ ufw status verbose
Then we’ll restart both servives Bind9 and the ufw with the following commands;
root@dnsmaster:~$ systemctl restart service.service
We could always restart and check status of the Bind9 DNS Server Service with following command.
root@dnsmaster:~$ service bind9 status
If everything is alright, the Bind9 status report will show no error. Beside, we could always visit this MxToolbox website for more detail reports and troubleshooting by entering the domain.

Ubuntu 17.10 Artful Aardvark!
Ubuntu 17.10, code named Artful Aardvark; I guess you already know that Artful means full of art or skill. And Aardvark is a medium-sized, burrowing, nocturnal mammal native to Africa. Colloquially, it is called African Ant Eater.
Nowadays Ubuntu become the world’s most popular desktop Linux operating system, and with its latest short-term support release, it’s clear Canonical want to keep a firm grip on the title.
‘Artful Aardvark’ (Ubuntu 17.10)
As release with Artful Aardvark (Ubuntu 17.10) in October 19, 2017 Canonical continues Ubuntu’s proud tradition of integrating the latest and greatest open source technology into a high-quality, easy-to-use Linux distribution. Ubuntu 17.10 Artful Aardvark marks an all-new chapter in Ubuntu’s already rich history. As always, the team has been hard at work through this cycle, introducing new features and fixing bugs.
Ubuntu 17.10 Debuts with An All-New Desktop
This is the first version of Ubuntu to use GNOME Shell as the default desktop. ‘The HUD, global menu, and other Unity features are no longer included’. By choosing to drop Unity most of Ubuntu’s home-grown usability efforts also fall by the wayside.
Ubuntu 17.10 Desktop
In Unity’s place comes a bespoke version of GNOME Shell that is ‘customized’ to resemble something that’s superficially close to the Unity desktop layout. The Ubuntu 17.10 desktop uses a two-panel layout: a full-height vertical dock sits on the left-hand side of the screen, while a ‘top bar’ is stripped across the top.
The top bar plays host a new type of app menu, a calendar applet/message tray, app indicators, and a unified status menu for managing network, volume, Bluetooth and user sessions.
Ubuntu Dock
The new Ubuntu Dock is both a task manager and an application launcher. It shows icons for open and running software windows as well as ‘pinned’ launchers for user’s favorite apps.
Ubuntu Dock
The dock is also global; it displays icons/applications from all workspaces regardless of which one user is actually viewing.
Both the Ubuntu Dock and the top bar are semi-transparent, which adds nice visual presence. When a window touches either element the “dynamic transparency” feature kicks in to render both dock and top bar darker, making panel label contents more legible in the foreground.
Activities & Workspaces
The main “desktop” area remains a usable space on which user can place icons, folders and files.
Though there’s no longer a true global app menu, but the majority of apps place a small menu in the top bar bearing the name of the app in focus. These app menus contain a solitary ‘quit’ button at the least, or a full complement of options at most.
Activities & Workspaces
Workspaces are a common feature found on most modern desktop operating systems including Windows 10, so it’s a good thing that Ubuntu hasn’t ditched them. User can easily move windows between workspaces by clicking on a window and moving it on over the workspace.
Applications Overview
In Ubuntu 17.10 Applications are listed alphabetically, ordered into scrollable pages. User can launch an application by clicking on it, selecting it with keyboard arrow keys and pressing enter, or by touching it.
Applications Overview
After years of ‘footnote’ releases that brought only minor tweaks, the ‘Artful Aardvark’ brings all-out with change, ready to usher in the new era. Under the hood, there have been updates to many core packages, including a new 4.13-based kernel, glibc 2.26, gcc 7.2, and much more in Ubuntu Desktop. Let’s have a brief list view on some of those updates.
- On supported systems, Wayland is now the default display server. The older display server is still available: just choose Ubuntu on Xorg from the cog on the log in screen.
- GDM has replaced LightDM as the default display manager. The login screen now uses virtual terminal 1 instead of virtual terminal 7.
- Printer configuration is now done in the Settings app: Choose Devices and then Printers. The tool uses the same algorithms for identifying printers and choosing drivers as the formerly used system-config-printer, and makes full use of driverless printing to support as many printers as possible.
- The default on screen keyboard is GNOME’s Caribou instead of Onboard.
- Calendar now supports recurring events.
- LibreOffice has been updated to 5.4.
- Python 2 is no longer installed by default. Python 3 has been updated to 3.6.
- The ‘Rhythm box’ music player now uses the alternate user interface created by Ubuntu Budgie developer David Mohamed.
- The Ubuntu GNOME flavor has been discontinued. If a user is using Ubuntu GNOME, he will be upgraded to Ubuntu.
Note: Install gnome-session and choose GNOME from the cog on the login screen if user would like to try a more upstream version of GNOME. If any user’ d like to also install more core apps, he’d install the vanilla-gnome-desktop met package.
Not only the Ubuntu 17.10 Desktop but also, there are significant changes into the Ubuntu 17.10 Server version too. For the Ubuntu Server 17.10, the OS Version for the printing server has been increased to announce Windows Server 2003 R2 SP2 ID mapping checks added to the testparm(1) tool. There are some ID mapping backends too, which are not allowed to be used for the default backend. Winbind will no longer start if an invalid backend is configured as the default backend. The others are as follows,
Ubuntu 17.10 Server
Qemu 2.10
Qemu has been updated to the 2.10 release. Since the last version was 2.8.
Among many other changes there is one that might need follow on activity by the user/admin: Image locking is added and enabled by default. This generally makes execution much safer, but can break some old use cases that now explicitly have to opt-in to ignore/share the locks by tools and subcommands using the –force-share option or the share-rw dqev property.
Libvirt 3.6
Libvirt has been updated to version 3.6.
LXD 2.18
LXD was updated to version 2.18. Some of the top new features of LXD 2.18 are:
- Native Ceph RBD support.
- Support for cloud instance types.
- Pre-seeding of the “lxd init” questions through yaml.
- New client library.
- Improved storage handling (volume resize, auto re-mapping on attach, …).
- A lot of small improvements to the client tool.
DPDK 17.05.2
Ubuntu 17.10 includes the latest release of DPDK that has stable updates: 17.05.2. This made it possible to integrate Open vSwitch 2.8.
Open vSwitch 2.8
Open vSwitch has been updated to 2.8. Though user need to specify dpdk devices via dpdk-devargs.
New BIND9 KSK
The DNS server BIND9 was updated to include the new Key Signing Key (KSK) that was published on July 11, 2017. Starting on October 11, 2017, that key will sign the root zone key, which in turn is used to sign the actual root zones.
Cloud-Init
The cloud-init version was updated to 17.1. Notable new features for cloud-init are as follows,
- Python 3.6 support.
- Ec2 support for IPv6 instance configuration.
- Expedited boot time through cloud-id optimization.
- Support for netplan yaml in cloud-init.
- Add cloud-init subcommands collect-logs, analyze and schema for developers.
- Apport integration from cloud-init via ‘ubuntu-bug cloud-init’.
- Significant unit test and integration test coverage improvements.
Curtin
The Curtin version is updated to ‘0.1.0~bzr519-0ubuntu1’. New features are:
- Network configuration passthrough for ubuntu and centos.
- More resilient UEFI/grub interaction.
- Better support for mdadm arrays.
- Ubuntu Core 16 Support.
- Improved bcache support.
Samba
Samba is updated to version 4.6.7. Important changes in the 4.6.x series are:
- Multi-process Net logon support.
- New options for controlling TCP ports used for RPC services.
- AD LDAP and replication performance improvements.
- DNS improvements.
There are many other changes too. We recommend that all users read the release notes, which document caveats, workarounds for known issues, as well as more in-depth Release Notes.
Users of Ubuntu 17.04 will be offered an automatic upgrade to 17.10. As always, upgrades to the latest version of Ubuntu are entirely free of charge.
Remember, here at eRacks, we offer pre-installed Ubuntu 17.10 Artful Aardvark with our new systems either directly from the OS dropdown, or by custom quote.

No Surprise: “The Hybrid Cloud Helps Midsize Companies…”
This is what we’ve been saying for years now – that the best path to the cloud is to:
- Own your core / foundation infrastructure and hardware, at least one server worth, and
- Architect it properly with DRY DevOps best-practices and repeatability, to scale into the cloud as needed to meet spot demand
Here’s the reference:

Why we Have to Say we Use Only New Components
Many of you may know this already, but:
- We build all our systems to order, and
- We only use factory fresh, new components in our new systems.
This may seem like an obvious thing to say, but it still needs to be said.
Why?
About 4-5 times a week, we get emails like the one at the end of this page –
Offering “Clean pull” components for low prices in large lots – At best, these would be considered “Refurb” components, but are really just plain used. They have a much shorter (or no) warranty period than new components – they’re also often factory seconds or grey market parts, sold sideways to dodgy suppliers so that they can build systems cheaper.
We do not use these suppliers.
So again, we always use 100% new and factory-fresh components in our new-system builds – (on occasion we sell our B-Stock systems, which are clearly marked as such, and what they are – reconditioned, etc).
Some of the additional ways it is possible to cut corners on building and assembling IT equipment, in addition to used or refurbished parts, is to use factory lot-ends, factory seconds, factory defects with a “Workaroundable” defect – this is how Dell got their start – they would buy large lots of, say, NIC cards (This was before motherboards came with them onboard!), with a known defect, and write (and pre-install) the Windows driver for it – almost always unbeknownst to the end-user, or disclaimed in fine print in the EULA that the customer is forced to accept.
In this market, with plenty of storage servers, with large numbers of 3.5″ hard disk drives, this is especially tempting for some box-builders to use components such as these – again, we do not do this, and *always* purchase new parts only, from reputable, nationally-known suppliers of components and computer parts for our servers, especially such as hard disks, etc.
We consistently see product out there in the marketplace which is built with these dodgy components, and have many times been asked by our new customers to help them bring these products up to spec with new parts, and re-test and burn-in to ensure reliability and a fighting chance at a full product lifetime.
Best,
Joe

Heads-Up for Half Petabyte Cloud-Ready Storage Servers
eRacks/NAS50 Half Petabytes of Data Storage Server / Cloud Storage
We were extremely excited to announce the forthcoming release of 500 Terabyte (half Petabyte) storage space upgrade on our flagship product eRacks/NAS50 cloud data storage servers last week. The new model, to be released shortly, will incorporate 50 HGST 10 Terabyte HelioSeal™ hard drives. While the new model is not released yet, we are accepting pre-orders from customers. The current capacity, now available, of the eRacks/NAS50 is 400Terabytes in total, with currently-available 8Terabyte drives. The Azure devops security for data protection purposes as that must be a priority.
The new unit is rackmount and holds 50 removable drive bays. The 9U unit is suitable for any cloud storage application as well as NAS/Local LAN, since cloud services are really used now a days, you can learn how connecting to clouds directly can help businesses from this link. eRacks/NAS50™ is also a great solution for media libraries and other applications which require massive amounts of data storage capacity, you just have to make you are also backed up by the best data management services. Visit https://blog.couchbase.com/fuzzy-matching/ and get more information!
Our new servers are truly a remarkable Petascale solution. The HGST 10 Terabyte HelioSeal™ drives that come with eRacks/NAS50 use two technologies that greatly add to the value that this server carries with it, including other server services from sites as https://www.servermania.com/kb/articles/what-are-the-requirements-for-ubuntu-server/ for ubuntu projects.
The first is referred to as the HelioSeal™ technology. The HGST hard drives using this technology replace the air inside of the drive with helium. This would make the drive much lighter as well as allowing the disks to be much thinner. Due to the helium inside, the thinness of disks will not cause any disruptive turbulence effects. This will allow us to have more disks inside each drive which in turn means more data space. Additionally, helium drives have much lower power consumption, as much as 27%, making our NAS50 models truly a green product.
The new drives in the eRacks/NAS50 servers also make use of a technology called SMR. That is short for Shingled Magnetic Recording. This technology by itself adds another 25 to 100 percent storage capacity to HGST hard drives.
We are proud of our new eRacks/NAS50 and are ready to take pre-orders. We are prepared to customize the unit per your instructions with all Open-Source software necessary so your order will reach you completely pre-installed.
Please contact us for pre-orders or any questions you may have.

eRacks NAS36 Servers Store More Data At Lower Cost
eRacks Systems NAS36 8TB Seagate Archive Drive upgrade
We can’t help it with our innovations. Our NAS36 servers offered almost 200 Terabytes of data space already. That is considered quite high for a mid-range data storage server. But we just decided to jump even higher and exchange the standard 6-terabyte disks into 8-terabyte ones. That mean our NAS36 model storage servers are now able to hold 288 terabytes of data in total.
The new NAS36 model with higher data capacity brings even more value to our customers not just because of the storage space it provides but also for its price. Yes, we have decided to slash the prices down below $25,000. That is going to bring considerable saving to our customers. [UPDATE Sep 2015: current price for maxed-out 288TB config with Seagate Archive 8TB drives is just under $22,000]
We are proud to announce this latest upgrade as we continue to provide petascale data storage servers at affordable prices.
We remain dedicated to open-source systems. We also remain committed to delivering pre-installed, pre-configured systems to our customers.
The NAS36 servers are rack-mount servers. We designed the 4U unit specially to hold large number of drives in a very limited space. That leaves ample amount of space for other necessary accessories inside your data center rack.
The 36 drives in the unit are all Seagate Archive Drives, mounted on a single backplane and controlled by a RAID controller. The unit holds 24 drives in front and 12 in the back making the unit case quite compact.
eRacks Systems is a leading provider of high-capacity, petascale data storage server solutions to companies and enterprises requiring massive amounts of storage data.
Our servers are suitable for application and web security on the cloud as well as Near-Line Storage. They are also configurable for NAS (Network Attached Storage) applications.
For a great storage solution at a considerable low price, contact us. We are available through email, phone and our website.
