How to get socket errors from 'connect'?

[David Lees]

I am running Python 2.0 under Redhat 7.0 Linux and trying to keep track
of error number on failed.  The code below will catch errors as an
exception, but I would like to look at the error number.  If I use
'connect_ex' mentioned in the Python documentation at:
http://www.python.org/doc/current/lib/socket-objects.html

I always get an error not caught by the Exception, so I am unable to
have the code look at the 'error indicator'

I also do not know how to access the 'error indicator'.  I see the
'errno' module which has the correspondence between a bunch of symbolic
names and their integer values, but this is no help as far as I can
tell.

Thanks in advance.
