Oh, yeah, hOOps :$

Is it, eh? Well, I'm from C, C++ and for me it just belongs there..:) but i'll
try to change my habits... :)
Hm weird now I get something like:
Traceback (most recent call last):
File "./TestService.py", line 14, in <module>
sock.connect((host,port))
File "<string>", line 1, in connect
TypeError: an integer is required
with this code:
#!/usr/bin/python
import sys
import string
from socket import *
usage="USAGE: "+sys.argv[0]+" <server> <port>"
if len(sys.argv) != 3:
print usage
sys.exit(0)
host = sys.argv[1]
port = sys.argv[2]
sock = socket(AF_INET, SOCK_STREAM)
sock.connect((host,port))
data = string.join("NovaxTest",'\n')
sock.send(data)
sock.close()
What does that mean? :(
Thanks,
Ron
