socket.getsockname is returning junk!!

[Wong Wah Meng-R32813]

Thanks. Someone pointed out that this could be due to a corrupted build, which I revisited the process. I included -lxnet in the linking process of the build, and this problem is resolved. The -lxnet was stated in README file for HP-UX Itanium build, which I somehow dropped it out in the middle of the process and wasn't aware it was essential as excluding it cost me the junk I was seeing. Problem solved!! Thanks a lot for reverting. :)

Regards,
Wah Meng

I'd say it's a problem with the _socket module; did the unit tests flag  
anything when you built Python?

On Windows, Python 2.7.1:

>>> server_address=('lepton', 11111)
>>> sock.bind(server_address)
>>> sock.getsockname()
('127.0.0.1', 11111)
