A little known feature of Catalyst 2.x Linux distributions is the ability to run your own kernel as an agent on a host, which allows you to run applications written in another language.
If you’re familiar with the Ubuntu Linux distribution, you’ll probably know that you can do this using the agent.
This is useful when you need to manage multiple Linux distributions or multiple servers, or when you want to install applications on multiple machines simultaneously.
But, what about a Linux distro like Ubuntu?
Or even Linux Mint?
There are some advantages to having a kernel agent running on your own system.
It can run more applications than a single host running its own kernel, and it can be run as an isolated process, like in the case of Ubuntu, or run in a container, like Mint.
In addition, you can control the agent through its configuration file.
Let’s start with the agent configuration file, and then we’ll go over how to install and configure it on your Linux machine.
Configure your Agent file in Ubuntu The first thing you need is a directory for your agent configuration.
This directory should be named ubuntu-agent-conf.conf and should be located in /etc/default/agent.conf.
Install Ubuntu Agent on Ubuntu A few days ago I started working on the agent for Ubuntu.
First, I wrote a small script that installs the agent, installs the dependencies and sets up a few defaults.
This script is called install-agent.sh and is located in the /etc directory.
Configuring the Agent for Ubuntu It is important that you set the agent’s path correctly, as this is the location where it will start the Ubuntu Agent service.
In this case, the path is /usr/local/bin: $ sudo mv /usr /local/libexec/ubuntu-agent-$(date +%s)-%d%H%M%S%T) /usr 4.
Installing Ubuntu Agent for Linux This is the same script, but instead of setting it’s path to /usr, it sets it’s current path to the agent root directory.
Instating Ubuntu Agent and Configuring Agent for OS X If you are running OS X, this is a little more complicated.
You need to configure your agent’s host and hostname.
You need to use the Host and Hostname properties of your agent.
Configating the Agent on OS X To use this script, you need the xauth-agent package from the Package Index.
To install it, run the following command in a terminal window.
sudo apt-get install xauth 1.
Install xauth for Ubuntu If you haven’t already installed it, you should do so.
Ubuntu is packaged with xauth by default, so you can install it by running the following commands in a Terminal window.
sudo apt-key adv –keyserver keyserver.ubuntu.com –recv-keys 6AAADF6-2B6C-4874-A8D9-9F7F7CEA7BC1 sudo apt install xen-xauth1-xen-agentxen This command downloads the xenagentx package.
This package contains a command-line tool called xauth that allows you, as an administrator, to control the actions of an agent.
This tool can be used to configure an agent, install applications, configure networking, and so on. xauth can be installed as a simple package in your package manager of choice, such as the apt-cache package.
If you want the x-auth package to install on all your systems, you may want to enable this.
If not, you will need to install x-agent separately.
You can do that by adding the following to the end of your /etc file: sudo apt update sudo apt -y install xconfig xauth Now, open your agent and run the x auth command to install it.
Now, if you are using a host with a default gateway, you don’t need to do anything.
To see what the agent will do when you start the agent on your system, type: sudo xauth –port 5555 This command will prompt you for a username and password, which will be the agent port number, 5555.
The agent will start in that port, but it will exit with a status of 1.
The output of xauth will look like this: [UbuntuAgent]:Agent Started: [Ub.1]: /usr: /usr:/bin:/usr:/lib/x86_64-linux-gnu/libxinit: /bin:/bin: /sbin:/sbin: [Ub.2]: /someserver: /var/run/xen.someservers: /etc:/etc:/bin The agent will now be installed on the host, and you
