Another reason that a socket can hang in the SYN_SENT state (besides trying to connect to an unreachable host without getting an ICMP destination-unreachable message in response): if the server's listen queue is full, it will silently ignore SYN packets until there is room in the queue. Sorry again about the "bukzor" vs. "buzkor" thing. I don't know what's causing your problem (and it's probably not a DNS issue after all) but it's more likely to be a server issue than a client one. Maybe your client has an unusually low socket timeout for some reason, though; does increasing it (with socket.setdefaulttimeout) help? Mine seems to default to about 75 seconds. If you can't work out the root cause, but it only happens every once in a while, you could try changing your client code to catch the socket exception and retry a limited number of times. -Miles -- http://mail.python.org/mailman/listinfo/python-list
