When I tried to register with Red Hat Network using up2date, I got a failure, and I copied the log file below, anyone can help me?

RHEL 5 does not use up2date, it uses yum. In order to use RHN you do understand that you need to have a paid registration?

RHEL5 uses rhn_register to register. The error messages looks like 1) it was smart enough to run rhn_register anyway; 2) you need to check your nameservers in /etc/resolv.conf.

I use GUI software update, actully I can login Red Hat Network on their websit.

Are you running through a proxy?
