Not able to ping

Hi All,

Need your help one more time.

I am trying to ping a linux machine which is not responding to ping.

However traceroute can reach the machine and I can log in to it by ssh. I have checked /proc/sys/net/ipv4/icmp_echo_ignore_all it is already set as "0".

It is not happening in the reverse direction as well.

I am clueless, can you please help me out?

Perhaps one end or the other has a firewall set up to block ping requests?

Try running:

$ sudo iptables --list

On each end to see if any firewall rules have been set up?
