Hi all,
I installed red hat 2.6.9-5 and when I am trying to ping it.I am able to ping any other machine in the network but unable to do vice-versa(means unable to ping this machine from any other machine) and getting the message --
please provide your valuable suggestions ...
Assuming network is configured correctly, most likely reason is firewall on server. try iptables -F to flush all firewall rule. Can you telnet/ssh to the server or ping to other machined from Linux ? if not, network/routing may be the issue
If this issue is not solved with the comments of dennysv, could you post "netstat -rn" from this box and other box recheable?
Other test you could try is make "arpping" to see if there is layer 2 conectivity
Also you could check the wire or even the port of the switch is in the same vlan.
