Two suggestions I can make. One is to use the command-line telnet utility to talk to the camera. Verify that you can at least make a connection and authenticate that way. Second, use a packet sniffer to watch the actual traffic going back and forth to the camera. On a Unix box, I would do: $ tcpdump -s 0 -A host 10.31.18.21 but it looks like you're on windows, so you'll want to use Wireshark (http://www.wireshark.org/) instead of tcpdump. If you're not familiar with TCP protocol details, you'll want to read up on it so you can properly interpret what tcpdump or Wireshark is telling you. -- http://mail.python.org/mailman/listinfo/python-list
