[CentOS] CentOS networking problem

2010-12-22 Thread Aravindh Ramaswamy
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..

 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
