Sometimes /list-ing channels is a nice way to find irc channels, but the more
interesting ones always have +s mode set - and the ircds don't usually support
listing so called "secret" channels for non ircops.. :)
Yet, this naming scheme is quite confusing, since the only thing +s really
changes - at least on ircds run by popular networks such as efnet and ircnet - is not
listing the channel in /who and /list and commands alike.
Direct requests to the channelname on the other hand will reveal the info inspite of
any +s oder +p modes.
Since I thought about publishing one or another irc script from my stash anyway, here is a small irc bot which will join to a specified channel and list all secret channels it finds by iterating a given wordlist - which can be quite a lot..
Net::IRC installed, either via cpan or via package manager,
on debian/ubuntu this is libnet-irc-perl.
perl toomanysecrets.pl and wait for the bot in the designated channel.
