Despite modern alternatives like Slack, the ancient IRC is still hugely popular as an online interactive chat platform.
This may be because there are IRC clients for almost every operating system and device, from the Commodore Amiga to your smartphone, and the technology behind IRC is reassuringly simplistic - it really is just raw text and a few control characters being bumped around the network.
Online servers, such as those offered by Freenode, are wonderful for both public and private channels. But it’s equally easy to run your own private IRC server, giving you complete control over your data, logs and configuration settings whilst avoiding all the risks and frustrations of dealing with IRC spammers and bots.
In this tutorial, we’ll cover installing the InspIRCd IRC server on Ubuntu, from installing its dependencies and building the latest version from GitHub, to configuration and execution.
What you’ll learn
- How to prepare your environment for the installation of InspIRCd
- How to build and install InspIRCd from GitHub
- How to start your first InspIRCd server
- How to configure InspIRCd
What you’ll need
- A computer running Ubuntu 16.04 LTS (Xenial) or later
- A network connection
- How will you use this tutorial? - Only read through it - Read it and complete the exercises
- What is your current level of experience? - Novice - Intermediate - Proficient
For the first step, we’ll install the dependencies needed to build and run InspIRCd, starting with git:
sudo apt-get install git
Next is Perl so we can run the configuration script included with InspIRCd:
sudo apt-get install perl sudo apt-get install g++
And finally we need to make sure that make is installed:
sudo apt-get install make
3. Download source
The latest version of InspIRCd can be downloaded from: https://github.com/inspircd/inspircd/releases/latest
As we’re going to be building the latest version from the source code, we need to grab the tar.gz archive either with your browser or from the command line. To take version
2.0.25 as an example, you could use the following command to download the archive:
Use tar to extract the download:
tar xvf ./v2.0.25.tar.gz
4. Build configuration
With the source code downloaded and extracted, we can now configure how we want InspIRCd built.
First, enter the installation directory:
To begin configuring the installation, enter the following:
You are now asked a series of questions. When unsure, press return to answer with the default values.
The final question will ask whether you’d like to check for updates to third-party modules, and you should answer
y for yes.
The final output should be similar to the following:
Ok, 144 modules. Writing inspircd_config.h Writing GNUmakefile ... Writing BSDmakefile ... Writing inspircd ... Writing cache file for future ./configures ... To build your server with these settings, please run 'make' now. *** Remember to edit your configuration files!!! ***
We can now proceed with the build step.
The server can now be built by executing
make in the installation directory. This process will take around 10 minutes, depending on your system speed, so feel free to step away from the computer.
With that complete, type
make install to move the executable files into the locations configured earlier. An overview of this process is output upon completion:

With InspIRCd fully installed, we can configure the server.
6. Server configuration
From the build directory, create a text file called
run/config/inspircd.conf and insert the following:
<config format="xml"> <define name="bindip" value="18.104.22.168"> <define name="localips" value="&bindip;/24"> ####### SERVER CONFIGURATION ####### <server name="SERVER_HOSTNAME/FQDN" description="SERVER_DESCRIPTION" id="SERVER_SID" network="NETWORK_NAME"> ####### ADMIN INFO ####### <admin name="ADMIN_NAME" nick="ADMIN_NICK" email="ADMIN_EMAIL"> ####### PORT CONFIGURATION ####### <bind address="SERVER_IP" port="SERVER_PORT" type="SERVER_TYPE">
Change the following values in the above text to reflect your own configuration:
- SERVER_HOSTNAME/FQDN: Hostname for the server
- SERVER_DESCRIPTION: A description for your server
- SERVER_SID: A unique sequence of 3 characters, the first being a number (make sure to capitalise)
- NETWORK_NAME: The name of your IRC network
- ADNIN_NAME: IRC admin name
- ADMIN_NICK: IRC admin nick
- ADMIN_EMAIL: IRC admin email
- SERVER_IP: Public IP for the server
- SERVER_PORT: Server port (usually 6697)
- SERVER_TYPE: The clients or servers type (clients should be fine here)
The configuration file should now look something like this:
<config format="xml"> <define name="bindip" value="22.214.171.124"> <define name="localips" value="&bindip;/24"> ####### SERVER CONFIGURATION ####### <server name="tutorials.ubuntu.com" description="Welcome to Ubuntu " id="97K" network="tutorials.ubuntu.com"> ####### ADMIN INFO ####### <admin name="tutorial ubuntu" nick="tutorial" email="firstname.lastname@example.org"> ####### PORT CONFIGURATION ####### <bind address="23.54.785.654" port="6697" type="clients">
Make sure you save your changes!
7. Run the server
It’s now time to start up InspIRCd for the first time!
In your the terminal window, type:
./inspircd start ./inspircd status
If successful, you will see the following output:
InspIRCd is running (PID: 13301)
Congratulations! Your server is now online!
Any IRC client capable of accessing your server will now be able to connect to your IRC server.
You now know how to:
- Grab source code from GitHub
- Prepare an environment to build InspIRCd
- Configure InspIRCd using a
- Start the service
- Modify your external internet connection to forward port 6697
- Ensure your network has a static IP address
- Get a URL to easily send traffic to your server (optional)
Changes to your IRC server need to be made to the config file and a list of supported commands and other useful information can be found at InspIRCd’s Wiki.
