up2date blue screen

Hi everyone,

This is my firs e-mail so, I hope write to the correct list.

I'm having a lot of problems trying to register and update a RHEL 4  
AS. When I execute "up2date", "up2date --register" or "up2date -u" I  
recive a simply blue screen and anymore.

The log "/var/log/up2date" don't show any message

The server haven't X, so I need configure and install through ssh.

Any help?


Thanks a lot,
Juanjo.
