Description Martin Poole 2007-07-31 17:43:50 UTC
Description of problem:

The addition of the default timeout of 30 seconds causes connection timeouts
against busy servers or those with many registered clients.

Version-Release number of selected component (if applicable):

2.1.1-3.el4

How reproducible:

Always against busy servers.

Steps to Reproduce:
1. Create secure server with 
2.
3.
  
Actual results:

# rhnreg_ks --activationkey=test-activation-key
Connection timed out on readline

Expected results:

No timeout.


Additional info:

The issue is with the DEFAULT_TIMEOUT in
/usr/lib/python2.3/site-packages/rhn/SSL.py and its use in connections.py.

Whilst a timeout of 30 seconds might not be unreasonable for the SSL connection
to take place it is not suitable for the ongoing connection. The socket timeout
should be reset to a more reasonable value once the SSL connection is in place.

Attached is a server-side cgi which just delays for a requested amount of time
and a small python script to exercise this cgi via the rhnlib code.
