Networks and servers
IRC Networks are made of servers, and servers have channels. You need to check in which network the channel you want to connect or create is hosted. Then, type
/network list to see the networks that are already configured on irssi. If the network that hosts your channel does not appear, you need to add it.
- Add a network.
/network add <network name> # e.g.: /network add LiberaChat
- Add a server to the network (check the network’s documentation).
/server add -network <network name> <server URL> <server port> # e.g.: /server add -network LiberaChat irc.libera.chat 6697
- Save changes to a user configuration file:
Join a channel
- Simply type
/join <channel name>:
Basic chat commands
/help: Shows a command list.
/help <command>: shows info about a command.
- PgUp or PgDown: scroll up or down.
/msg <username> <message>: send a private message.
/part [channel name] [message]: leave a channel and advertise it with an optional message.
/quit: close irssi.
- Ctrl + P: go to previous window.
- Ctrl + N: go to next window.
Register a username
- Connect to your network:
/network connect <network name>
- Change your username:
/nick <username> # e.g.: /nick JohnDB
- Register the username:
/msg NickServ REGISTER <password> <email>
- You will receive a confirmation email, you need to copy the command on the email and paste it on irssi.
- SASL is a identification method recommended for LiberaChat. Once registered a username, edit network to allow SASL.
# Replace <login> and <password> with the username and password and use the same <network name> to edit it. /network add -sasl_username <login> -sasl_password <password> -sasl_mechanism PLAIN <network name>
- Edit the server:
/server add -auto -net <network name> -tls -tls_verify irc.libera.chat 6697 # you can remove -auto to avoid irssi to connect automatically to the server
- Save the changes:
Request a generic user cloak
A cloak are custom hostmask that replace your client hostname or IP address. To limit the exposure of your IP address, you can request a cloak by joining
#libera-cloak channel (
/join #libera-cloak) and typing
Get info about a channel
/msg ChanServ INFO <channel name>
