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

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..
Thank you sir for replying..
Given below is my system's status after 'ifconfig'...
