Description of problem:
Customer is using RHAS 2.1 and wants to register his system with RHN.

We configured his proxy settings using "up2date --configure" and
entered the correct "proxyserver:port" values. We double checked by
using the same proxy settings in mozilla and he confirmed that he can
browse http://rhn.redhat.com.

We executed "up2date" or "rhn_register" to register the system but
failed with an error message which says "no route to host". 

We tried "telnet xmlrpc.rhn.redhat.com 443" and it was successful.

We looked into the file /usr/share/rhn/register/hardware.py and in
line #273 we saw this code:
    s.connect((server, 80))

We changed port 80 to 443 and everything now works!

There is no way to change these settings using any currently available
tool since the port number (80) is hardcoded into hardware.py. 

We assumed that port 80 has been blocked but port 443 is open. We
could not confirm the port 80 blockage since the customer is NOT the
network admin. 


Version-Release number of selected component (if applicable):
rhn_register-2.9.2-1.2.1AS

How reproducible:
Always

Steps to Reproduce:
1. "up2date --configure" and supply the correct proxyserver:port values
2. "up2date" or "rhn_register" to register the system with RHN
3.
    

Actual Results:  Error message says:

   no route to host

Expected Results:  System should be registered with RHN with no problems.

Additional info:

Possible blockage of port 80. We could not confirm this though.

The network admins must have forwarded port 443 to the proxy server
but blocked the normal http port. Users can therefore browse the
internet using the correct proxy settings or telnet outside to port 443.
