Description of problem:
When you define a proxy host in rhn-register --config, it truncates the
first 7 characters of the hostname. A workaround is to pad the beginning
of the hostname with garbage characters. This is easily reproducible.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. run rhn-register --config
2. select option 2, httpProxy
3. input hostname
4. run rhn_register
Actual Results: Error: Host not found
Expected Results: It should have proceeded into the rhn_register setup.
This happens with both the gui and text versions. If you pad the first 7
characters of the hostname with characters, it works fine.
This is fixed in the 7.2 version of the client,
and in an errata for 7.1 to be issued soon.
