Today I was in the mood to do yum update on my test CentOS box. Everything started pretty normal, amount of data to download and so on. Later on data was downloading when on one package with following error:
Package name [Errno 12] Timeout on Package name:(28, 'Operation too slow. Less than 1 bytes/sec transfered the last 30 seconds')
Trying other mirror.
Recently I found that on my VPS server there is incorrect time often called time drift. As you know having correct time is very important - especially in Active Directory environments. Back to my case - I have VPS running on XEN and I reported to hosting company this issue. They replied that they will not change ntp settings for hosts but they said that I can do it by myself.
So encouraged by them (of course by not solving my ticket at all) I did small digging and I found this solution.
