Some body help because am stuck. when I run the yum update command on the CentOS 5.0 server it gives the following error message; # could not retrieve mirrorlist http://mirrorlist.CentOS.org/?release=5&arch=i386&repo=os error was[Errno 4] IOError:<urlopen error( -3,'Temporary failure in name resolution')> What can I do?
you can check your networkconnection especially the dns setup. e.g. can you lookup the dns name of the server: What does /etc/resolv.conf contain? It should contain valid nameservers, than will do the lookup of the internet namespace, or at least a local dns-server that resolves it either as forward or with recursion
