Ergo (formerly known as Oragono) is a modern IRC server written in Go. Its core design principles are:
Ergo is a fork of the Ergonomadic IRC daemon <3
If you want to take a look at a running Ergo instance or test some client code, feel free to play with testnet.ergo.chat (TLS on port 6697 or plaintext on port 6667).
UBAN
, a unified ban system that can target IPs, networks, masks, and registered accounts (KLINE
and DLINE
are also supported)For more detailed information on Ergo's functionality, see:
Download the latest release from this page: https://github.com/ergochat/ergo/releases/latest
Extract it into a folder, then run the following commands:
cp default.yaml ircd.yaml
vim ircd.yaml # modify the config file to your liking
ergo mkcerts
ergo run # server should be ready to go!
Note: See the productionizing guide in our manual for recommendations on how to run a production network, including obtaining valid TLS certificates.
Some platforms/distros also have Ergo packages maintained for them:
A Dockerfile and example docker-compose recipe are available in the distrib/docker
directory. Ergo is automatically published
to the GitHub Container Registry at ghcr.io/ergochat/ergo. For more information, see the distrib/docker
README file.
You can also clone this repository and build from source. Typical deployments should use the stable
branch, which points to the latest stable release. In general, stable
should coincide with the latest published tag that is not designated as a beta or release candidate (for example, v2.7.0-rc1
was an unstable release candidate and v2.7.0
was the corresponding stable release), so you can also identify the latest stable release tag on the releases page and build that.
The master
branch is not recommended for production use since it may contain bugs, and because the forwards compatibility guarantees for the config file and the database that apply to releases do not apply to master. That is to say, running master may result in changes to your database that end up being incompatible with future versions of Ergo.
For information on contributing to Ergo, see DEVELOPING.md.
You'll need an up-to-date distribution of the Go language for your OS and architecture. Once that's installed (check the output of go version
), just check out your desired branch or tag and run make
. This will produce an executable binary named ergo
in the base directory of the project. (Ergo vendors all its dependencies, so you will not need to fetch any dependencies remotely.)
The default config file default.yaml
helps walk you through what each option means and changes.
You can use the --conf
parameter when launching Ergo to control where it looks for the config file. For instance: ergo run --conf /path/to/ircd.yaml
. The configuration file also stores where the log, database, certificate, and other files are opened. Normally, all these files use relative paths, but you can change them to be absolute (such as /var/log/ircd.log
) when running Ergo as a service.
By default, logs go to stderr only. They can be configured to go to a file, or you can use systemd to direct the stderr to the system journal (see the manual for details). The configuration format of logs is designed to be easily pluggable, and is inspired by the logging config provided by InspIRCd.
Passwords (for both PASS
and oper logins) are stored using bcrypt. To generate encrypted strings for use in the config, use the genpasswd
subcommand as such:
ergo genpasswd
With this, you receive a blob of text which you can plug into your configuration file.
Ergo relies heavily on user accounts to enable its distinctive features (such as allowing multiple clients per nickname). As a user, you can register your current nickname as an account using /msg NickServ register <password>
. Once you have done so, you should enable SASL in your clients, ensuring that you will be automatically logged into your account on each connection. This will prevent problems claiming your registered nickname.
Once you have registered your nickname, you can use it to register channels:
/join #channel
/CS REGISTER #channel
After this, your channel will remember the fact that you're the owner, the topic, and any modes set on it!
