Shalom Suman,

Please provide commands and error message.

If the networks are not all connected, this can cause this issue.

Check the gateway on the network configurations that don't work. This is often the cause of these problems.

hello,

I am just giving the ping command,no other command.I can tell you the ip range of all servers.
1.Master server:192.168.111.239
2.slave: 192.168.111.240

3.license server:192.168.111.211
4. same : 192.168.124.231
5.10.66.75.151

4,5 r not pinning by slave server,but it is pinging by master,config r same..

is that any gate way problem,what could be the issue,server r situated in diff location.3,4,5 are in cluster...

Most likely it is a routing problem. Run the following cmds. on the master and slave servers and post the outputs:

# netstat -in
and
# netstat -rn

You can also make a tcpdump on both sides, to
see if you send & receive the ICMP ECHO /ECHO reply messages

you can use also traceroute from both end, to check where the way is cut.

There is also ping '-o' option which is similar to traceroute.
