Description of problem:
While running rhn_register from the console I get the following:
Traceback (innermost last):
  File "/usr/sbin/rhn_register", line 233, in ?
    main()
  File "/usr/sbin/rhn_register", line 214, in main
    tui.main()
  File "/usr/share/rhn/register/tui.py", line 1042, in main
    tui.run()
  File "/usr/share/rhn/register/tui.py", line 986, in run
    win = self.windows[index](self.screen, self)
  File "/usr/share/rhn/register/tui.py", line 567, in __init__
    tui.hardware = hardware.Hardware()
  File "/usr/share/rhn/register/hardware.py", line 374, in Hardware
    ret = read_network()
  File "/usr/share/rhn/register/hardware.py", line 296, in 
read_network
    hostname, ipaddr = findHostByRoute()
  File "/usr/share/rhn/register/hardware.py", line 276, in 
findHostByRoute
    hostname = socket.gethostbyaddr(intf)[0]
socket.error: host not found

This occurs right after I input my rhn account information.
If I am running the Gnome client, I get past the login screen and the 
next screen shows errors for all options (OS, Version, etc).

Version-Release number of selected component (if applicable):
rhnlib-1.3-11.152
rhn_register-gnome-2.9.2-1.2.1AS
rhn_register-2.9.2-1.2.1AS
up2date-gnome-2.9.3-2.2.1AS
up2date-2.9.3-2.2.1AS

Installed from RHAS2.1 Update 3 iso's
How reproducible:
running rhn_register from console or gnome

Steps to Reproduce:
1.run rhn_register
2.accept license agreement
3.enter account information
4.click next 
  
Actual results:
Traceback (innermost last):
  File "/usr/sbin/rhn_register", line 233, in ?
    main()
  File "/usr/sbin/rhn_register", line 214, in main
