How can I make my bot join a keyed (+k) channel?
The simplest way to do this is to set the channel's key in the enforced modes by using the chanset command, e.g. .chanset #channel chanmode +nstk <key> (you can view the current enforced modes using .chaninfo #channel). The bot will then automatically use that key to join.
Alternatively, if you don't want +k to be enforced by the bot for whatever reason, you might want to try a script for making the bot join keyed channels.

is das ein statischer channel? dann mussu das vmtl in der eggdrop.conf eintragen. das geht btw auch per dcc chat auf der partyline nicht nur via telnet.
