Premier lancement d'irssi :

$ irssi

On peut faire la configuration directement depuis irssi. Ici, un exemple pour se connecter au gateway IRC de Slack :

/network add -nick <nickname> slack
   13:53 -!- Irssi: Network slack saved
/server add -auto -ssl -network slack <account>.irc.slack.com 6667 <password>
   14:05 -!- Irssi: Server membrecalibanbelgique.irc.slack.com saved
/save
   14:05 -!- Irssi: Saved configuration to file /home/simon/.irssi/config

On quitte :

/quit

Et on relance irssi :

$ irssi

Une fois qu'on a configuré le serveur comme vu précédemment, Irssi s'y connecte au démarrage :

14:18 -!- Irssi: Looking up membrecalibanbelgique.slack.com
