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..
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?
