Aravindh, Tell us a little bit about your current server hardware, are your NICs showing using ifconfig, what about your gateway sing route. It would be good to know a little bit about your current configuration, including if you are using IPv6. Please elaborate so we can help you further. Lisandro >>> Aravindh Ramaswamy 12/22/10 11:17 PM >>> Sir/Madam, This is Aravindh,final year student of Anna University India.We are carrying on research in Cloud Computing and using Open Nebula toolkit for that;for which we need strong network connectivity. The problem i am facing is that i am not able to ping continuously to other nodes in the network. The connectivity is getting lost after 2-3 minutes. we have inspected the connectivity links , switch etc. and found them to be normal. In fact it pings continuously in other OS. Is there any problem in CentOS network connectivity packages? Help needed urgently.. -- Thanks and Regards, Aravindh.R -------------- next part -------------- An HTML attachment was scrubbed...
