I can't get the timeoutsocket module to work on my Redhat Linux! (The
timeout works fine on Windows 2000.) I'm running Python 2.2.2.

Here's the test code:

import timeoutsocket
timeoutsocket.s etDefaultSocket Timeout(1)
s = timeoutsocket.s ocket(timeoutso cket.AF_INET, timeoutsocket.S OCK_STREAM)
s.connect(("www .google.com", 80))
s.close()

Any ideas?

I might add, that I conducted the test by running the above code
with and without my Ethernet cable plugged to the computer. When it was
plugged connect() worked just fine, when unplugged, the connect() call
timed out on Windows as expected but not at all on Linux.
