Problems: Error communicating with server
Hi, everyone. I am new user to Linux. I am using RHN system. Today, I were running Yum, some errors appeared as the below.
Before, I had never such problems. I tried to search some solutions in Google, but can not find it. Can anybody help me?
Thanks a lot!
[root]# Yum install xorg-x11-server-Xvfb
[root]# Yum list updates
There was an error communicating with RHN
RHN support will be disabled
Error communicating with server. The message was: Connection timed out
