CentOS - Dec 2010 - CentOS networking problem

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,
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

Pinging continuously can be detected by some firewall as part of
denial-of-service attack, which can then block ICMP packages, even
block them selectively.

How often are you pinging, and from how many other nodes?
