Configuration of Linux server Kb Arubacloud com

We aim to include more new functionality via this in coming releases. If you are running TurnKey v15.x – with Confconsole v1.1.x – these instructions do not apply. V15.x users need to carefully follow the v1.1.2 Release notes. If you have problems or questions, please post on our support forums. For v16.x (Confconsole v2.0.x) users, the Let’s Encrypt bug has been resolved and it should “just work”. However, if you wish to ensure that you are running the latest, please see below for how to upgrade to the latest version. As of v2.x (default in v16.x TurnKey appliances), Configuration Console will be invoked automatically on first log in.

How do I open and edit a CFG file?

  1. Click the Windows "Start" button.
  2. Right-click the "CFG" file displayed in the results window.
  3. View the file and edit any configurations you want to edit.

In this case, you will use an application like Nano or Vi to open each configuration file and edit them. In REHL, each configuration file will be listed as a separate file as mentioned above. Ubuntu has each configuration listed within that Interface file, though, under the /etc/network/ file system path. Much like Windows, Linux holds a configuration file for each network interface. It is important to note that a network interface could be either a virtual or physical device or a wired or wireless device. These configuration files tell the operating system things like the name of the interface, whether it should use DHCP, or if IPv6 should be enabled. Though settings are saved immediately after saving an edited config file, applications won’t pick up those settings changes until the application is restarted.

A Last Note for Configuring Network Interfaces in Ubuntu

Whether you make your way to the courses or not, hopefully now you’re a little more comfortable configuring your Linux OS and network. If you are using the standard version of Ubuntu, use the ‘sudo systemctl restart network-manager’ command. If you are using the server version of Ubuntu, use the ‘sudo systemctl restart system-networkd’ command instead. Likewise, you can restart the computer system for those changes to take effect, too. You need to restart the network services for those changes to take effect.

  • The /etc/sysconfig/network-scripts/ directory contains multiple files for each network interface.
  • Things like drivers can be included directly in the kernel or as modules that can be added or removed at any time.
  • Many Linux configuration files can be opened with a plain-text editor and updated directly, though you will most likely be using a command-line editor like Nano or Vim to edit these files.
  • Once the application or service finds the data it needs, it stops looking.
  • DHCP is mostly configured behind the scenes, but there are times when administrators need to tweak DHCP settings a bit.
  • Whether you’re aiming for a certification or just an understanding of the technology, consider taking a CBT Nuggets course in Linux.

That means if you need a web server, you only need to install Apacheor Nginx without tons of other services and features that you don’t need. A few utilities may even have expansion symbols that help with managing and distributing centralized files.

Look and Feel (User Interface)

The main configuration file includes all files in another directory. Files in the directory may originate from different RPM packages. The configuration directory contains configured files which configures the parameters and initial settings for some computer programs.

Broadly speaking, Linux configuration files can be of the following types. Each nameserver entry requires two addresses within the bracket notation above. Likewise, I used Google’s DNS address for my secondary DNS entry ( The etc/sysctl.conf is a potentially powerful tool to tinker with if you’re not sure what you’re doing. If you run the command “sysctl –system”, you can see what commands and files the OS tries to load and in what order. It’s not a dry-run command — that means it will actively load and run operations on your OS.
