Trying to update a second CentOS box, I'm getting this error repeatedly: [Errno 4] Socket Error: timed out I'm getting this on every mirror and have gone through the list of mirrors more than a dozen times. Oddly, the RPMs I'm trying to upgrade I upgraded just yesterday without a problem on another machine on the same LAN with no problems whatsoever. I can ping mirrors fine. There were a spate of these errors back in 2006. The fix for many was to add this line to yum.conf: timeout=300 So I did that on the machine where yum is having the problem, but the same errors are returned. Anyone else seeing this? Anyone know what the problem is?
