[Spacewalk-list] Yum doesn't communicate with server

[Nilton Moura]

Hi!
I have some Red Hat hosts freshly registered with Spacewalk, but one
specific (5.4) won't communicate with the server on yum command.

$ sudo yum search rhncfg
Warning: No matches found for: rhncfg
No Matches found

I upgraded yum* packages manually, but the problem still. No traffic is
generated to the server when I watch with tcpdump. yum clean all, etc..

Someone has any idea?

Thanks,
Nilton.
