Ping echo not returns
Hi there,
I have 2 HP-UX on same subnet and having a problem on one about ping. I'll call them as hp01 hp02.
hp01 can ping hp02 (ping says %100 transmitted)
hp01 can ssh/telnet hp02
hp02 can ssh/telnet hp01
hp02 cannot ping hp02 (ping says %100 packet loss)
There I thought of ndd commands to set "ip_forwarding" as it could be the cause but it still didn't affect to behave normally.
I don't know if this problem exists since the installations.
Any ideas about what it could be?
Thanks,

echo `echo ` doesn't echoes anything. And it's logic. But
