Ping echo not returns

UNIX HP-UX
1

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, :confused:

What is the network between them like?

3

They are on the same subnet. :rolleyes: 1000 full duplex if that's what u'r asking about.

4

And their IP addreses, netmasks, routing tables, etc?

Ok, I don't understand asking that info, as if shouldn't ssh/telnet otherwise. Solved the problem.

IPfilter coming with the installation had a default setting enabling 22 but rejecting ICMP. Flushing the filter table made it right

ipfstat -io
ipf -Fa
ipfstat -io

then ping echo comes :cool:
