Hi there,

I am having some network issues and I am not sure what log files I should be looking at. Every day I have to issue a "service network restart" due to some network failure. If I could look at some sort of log file to sort out why it's failing that would be great, but I am not sure which files to look at. /var/log/messages perhaps? I'm on a Centos 5 box. Thanks.

Jim

Hi,
I think that your message is associate with
http://forum.openvz.org/index.php?t=tree&th=5314&sta rt=0&

Can you please describe more exactly your configuration?
- Are you using private or public IPs on your HN and VEs?
- Is it possible to ping google.com (from your example) using it IP address?
- Please check the routing table? Any iptables rules?
- And you could use "tcpdump" utility to observe the net behavior?
- I think that if something was wrong you can find any strange messages in /var/log/messages. Also you could check /var/log/vzctl* (I don't remember exactly).
