1) Download the latest version of the Webmin Control Panel. You will want to use the RPM Build.
# wget https://prdownloads.sourceforge.net/webadmin/webmin-1.730-1.noarch.rpm2) Install the package: Continue reading Setup Webmin Control Panel on Your Server
The Apache web server is the most popular web server all over the world. Virtual hosting is a method for hosting multiple websites (domains) on a single server. You can host multiple websites on a single machine with a single IP using virtual hosting. All domains on that server will be sharing a single IP. Virtual hosting is very useful in shared web hosting environments, where hundreds of websites are hosted on a single dedicated server.
In this article we will be hosting two websites (www.vhost1.com and www.vhost2.com) on a single IP address (192.0.2.0).
A common network infrastructure may consist of an private network on an isolated subnet. While there may be no need for incoming connections to access the private network from the outside, there are occasions when you may need servers within the private subnet to make connections to services outside of the subnet or to the public Internet. An example may include downloading a software package, sending backup data to an external location, or applying system updates to servers on the private subnet.
A Linux gateway server with two network interfaces, or NICs, can be used to bridge two networks together. One NIC will connect to an external, or public, network while the other NIC will connect to the private subnet. IP forwarding and a NAT rule are then used to route traffic from the private subnet out to the external network.
The traffic from the internal servers will appear to be originating from the gateway IP address. Externally generated traffic will reach the gateway and have no visibility of the private subnet.
While beyond the scope of this tutorial, the gateway server firewall can be modified to restrict outbound traffic from the subnet. Continue reading Deploy Outbound NAT Gateway on Ubuntu
A gateway is a node or a router that acts as an access point to passes network data from local networks to remote networks. There are many ways to find out your gateway in Linux. Here are some of them from Terminal.
You can find default gateway using ip, route and netstat commands in Linux systems.
Using route command
Open up your terminal and type the following commands:
sk@sk:~$ route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0 eth1 192.168.1.0 0.0.0.0 255.255.255.0 U 1 0 0 eth1
The above output shows my default gateway is 192.168.1.1. UG stands for the network link is Up and G stands for Gateway. Continue reading How to Find Default Gateway in Linux
After Nemo and Nautilus, now we bring you Thunar. It is one of the simplest file manager (graphical) available in Linux. Simple means Thunar is easy to use. We will cover some important features of Thunar. We hope it helps new users into Xubuntu or any XFCE based Linux distro.
After Thunar, we come with PCManFM. This is the LXDE file manager. You’ll find PCManFM in Lubuntu. PCManFM is a very lightweight file manager yet powerful. It has search facility, something Thunar doesn’t. It has F3 Split View also, something Nautilus doesn’t anymore. And just like another file managers available in Linux, it has multitab feature. We hope this article helps anyone using Lubuntu or any LXDE based Linux everywhere. Enjoy.
Ubuntu gives us easy way to bind a shortcut key with any program. Suppose you want to open Firefox when Win+G are pressed. Or press Win+H to open text editor. This can be achieved by using internal Ubuntu System Settings. You don’t need to install any external program.
Open System Settings (gear logo) > Keyboard > Shortcuts > press Custom Shortcuts > press plus (+) button. Here, name your shortcut i.e. Mozilla Firefox and type the command. You must know the command exactly, e.g firefox is command for Mozilla Firefox. Another command examples such as brasero for Brasero, thunderbird for Mozilla Thunderbird, evince for Evince, and so on. Remember that they are case sensitive. Now, click the line you’ve created and press the keys i.e. Win+H.
Suppose you want to execute a command line from keyboard shortcut. For example, turning the brightness down/up. Of course, there are thousands and more possible commands to bind with shortcut key. Imagine you can pipe or redirect somethings by just pressing shortcut key. To do it, do the same like normal applications and type the command line i.e. xrandr –output LVDS1 –brightness 0.5 to turn brightness down and xrandr –output LVDS1 –brightness 1 to turn it up. Again, after typing a command, click the line you’ve created (see right panel) and bind the keys i.e. Win+J.

Fedora is used for all Embedded Development activities/workflows (cross-tools, alternate libc, RT, romfs, root flash, small footprint targets, etc.) that target the full spectrum of system platform-OS-application combinations:
Embedded targets that run (at least some portion of) Fedora include x86, x86_64, Blackfin, ARM and others.
Fedora includes support for developing non-Linux embedded applications targeted at the Microchip PIC, a common embedded microcontroller, and the Atmel AVR. There is also limited support for other parts. Continue reading Packages For Embedded Development
Jonathan Riddell, the Kubuntu Release Manager, has announced he’s stepping down.
Major shock — not.
The former project leader¹ and long-time KDE developer confirmed the news in a blog post on the Kubuntu website, as well as in an e-mail sent to the Ubuntu Devel mailing list.
“Making Kubuntu over the last 10 years has been a fantastic journey,” he writes.
“Even (sic) since I first heard about a spaceman making a Linux distro using Debian but faster release cycles I’ve known this would be something important and wanted KDE to be part of it. Bringing together KDE and Ubuntu has created the best operating system we can and the best community to work on it.”

The Ubuntu 16.04 LTS codename has been revealed — and, unsurprisingly for a release beginning with ‘x’, it’s a little obtuse.
The Ubuntu 16.04 name is ‘Xenial Xerus’.
It is the successor to Wily Werewolf, and the next Long-Term Support release.
Xenial is an adjective meaning ‘hospitable’ or ‘friendly’, while xerus is the posh name given to a ground squirrel.
Announcing the name of Ubuntu 16.04 LTS on his blog, Ubuntu founder Mark Shuttleworth explains the codename further:
“What fortunate timing that our next LTS should be X, because “xenial” means “friendly relations between hosts and guests”, and given all the amazing work going into LXD and KVM for Ubuntu OpenStack, and beyond that the interoperability of Ubuntu OpenStack with hypervisors of all sorts, it seems like a perfect fit.
And Xerus, the African ground squirrels, are among the most social animals in my home country. They thrive in the desert, they live in small, agile, social groups that get along unusually well with their neighbours (for most mammals, neighbours are a source of bloody competition, for Xerus, hey, collaboration is cool). They are fast, feisty, friendly and known for their enormous… courage. That sounds just about right. With great… courage… comes great opportunity!”
X is also fitting for another reason: Ubuntu 16.04 is expected to be the last version of Ubuntu to ship with the standard X server by default. Canonical’s home-grown Mir display server and Unity 8 shell are maturing nicely, aiming to replace the default offerings in Ubuntu 16.10 due in a year’s time.
Mark describes Utopic, Vivid and Wily as “three intense releases, packed with innovation”, adding that Ubuntu 16.04 LTS will ‘bring the threads together…making Ubuntu the fastest path to magic of all sorts”.
