Socket.error: [Errno 10054]

Question

import socket, sys

if len(sys.argv) !=3 :
print "Usage: ./supabot.py <host> <port>"
sys.exit(1)

irc = sys.argv[1]
port = int(sys.argv[2])
sck = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sck.connect((irc, port))
sck.send('NICK supaBOT\r\n')
sck.send('USER supaBOT supaBOT supaBOT :supaBOT Script\r\n')
sck.send('JOIN #darkunderground' + '\r\n')
data = ''
while True:
      data = sck.recv(1024)
      if data.find('PING') != -1:
         sck.send('PONG ' + data.split() [1] + '\r\n')
         print data
      elif data.find('!info') != -1:
          sck.send('PRIVMSG #darkunderground supaBOT v1.0 by sourD' + '\r\n')


print sck.recv(1024)

when i run this code i get this error.

socket.error: [Errno 10054] An existing connection was forcibly closed by the remote host

states that the error is on line 16, in data = sck.recv (1024)

Answer 1

You need to check the IRC protocol a bit; your IRC session is not considered connected (server) until certain actions are performed that the server will inform your client about the use of IRC protocol codes. And if the server or network is busy when you connect, it will take longer to complete these steps.
