I'm making an IRC bot in python for the hackthissite challenge (prog 8). Here's an excerpt of the connection code:
def ping():
ircsock.send("PONG :Pong\n")
ircsock.connect((server,6667))
ircsock.send("USER "+botnick+" "+server+" "+botnick+" :"+version+"\n")
ircsock.send("NICK "+botnick+"\n")
while(connect):
ircmsg = ircsock.recv(2048)
ircmsg = ircmsg.strip('\n\r')
print(ircmsg)
if(ircmsg.find("PING :") != -1):
ping()
I don't think that there's anything wrong with this. All variables are defined and have a value, this code works without a problem on some servers (freenode for example). But on other servers (foonetic, hackthissite) I get the following output:
:hub.irc.hackthissite.org NOTICE AUTH :*** Looking up your hostname...
:hub.irc.hackthissite.org NOTICE AUTH :*** Found your hostname
PING :3C8E9173
:3C8E9173!nospoof@hub.irc.hackthissite.org PRIVMSG Tadbot :VERSION
I'm not sure what to do with this. I have tried sending back the version of my bot to the username between the ":" and the "!", which (as expected) didn't do anything. On servers where this happens, I never get my MOTD so I get the "You have not registered" error when I try to do anything.
Google yielded some results of people explaining similar problems, but it'd always be that they forgot to send their USER and NICK, so I'm really at a loss about what to do here.
You must send the PONG response to the server's PING, otherwise the server will think the connection is dead.
The correct reply in the example you posted would be
PONG :3C8E9173
3C8E9173 being the same string as the server requested.
