I am fairly new to linux, and brand new to yum (switching from Suse to CentOS). I have been reading tutorials, and centos forum discussions, but I can't get yum to work: [root@localhost home]# yum check-update Setting up repositories dries 100% |=========================| 951 B 00:00 dag 100% |=========================| 1.1 kB 00:00 jpackage-fc 100% |=========================| 951 B 00:00 update 100% |=========================| 951 B 00:00 jpackage-generic 100% |=========================| 951 B 00:00 base 100% |=========================| 1.1 kB 00:00 jpackage-rhel 100% |=========================| 951 B 00:00 contrib 100% |=========================| 951 B 00:00 centosplus 100% |=========================| 951 B 00:00 addons 100% |=========================| 951 B 00:00 extras 100% |=========================| 1.1 kB 00:00 Reading repository metadata in from local files primary.xml.gz 100% |=========================| 160 kB 00:38 http://ftp.belnet.be/packages/dries.ulyssis.org/redhat/el4/en/i386/dries/RPMS/repodata/primary.xml.gz: [Errno 4] Socket Error: timed out Trying other mirror. Error: failure: repodata/primary.xml.gz from dries: [Errno 256] No more mirrors to try. I have the keys installed. I have tried using the base urls in the centos-base.repos, but when the computer is "Reading repository metadata in from local files primary.xml.gz" it times out after about 15 seconds. There is constant progress on the status bar, but it only gets 20%, or so, before timing out, and delivering the errors. I am assuming there is a problem with my settings, but I don't know what to do from here. Any suggestions? TIA
