Supybot

I just wondered why my bot didn't react to private messages.

Well, strace-ing shows the reason clearly:

poll([{fd=3, events=POLLOUT, revents=POLLOUT}], 1, 1000) = 1
send(3, "PRIVMSG smurf :OK\r\n", 19, 0) = 19
gettimeofday({1198864760, 874593}, NULL) = 0
gettimeofday({1198864760, 874641}, NULL) = 0
poll([{fd=3, events=POLLIN, revents=POLLIN}], 1, 1000) = 1
recv(3, ":brown.freenode.net 505 locovotebot :Private messages from
unregistered users are currently blocked due to spam problems, but you can
always message a staffer. Please register! (
http://freenode.net/faq.shtml#privmsg )\r\n", 1024, 0) = 220
gettimeofday({1198864761, 49120}, NULL) = 0
gettimeofday({1198864761, 50958}, NULL) = 0
gettimeofday({1198864761, 51705}, NULL) = 0
gettimeofday({1198864761, 51781}, NULL) = 0
poll([{fd=3, events=POLLIN}], 1, 1000) = 0

Error messages from IRC servers need to be logged!
