ping response not showing TTL

Hi all,

When I ping (/usr/sbin/ping) a host from HP-UX 11i (B.11.11), the
responses do not include the TTL value.
Tried looking at the man page but could not find a way to show the
TTL. Pls advise.

Thanks!

Short of porting another ping program, or submitting the enhancement
request, you might use traceroute to get the hop-count between
systems.

You could also I suppose take a nettl or tcpdump trace of the traffic
and inspect the IP headers directly.

HP-UX 11.11 ping does seem to claim a -t option to set the TTL,
ostensibly one could use that to binary search the hop count.
However, my experiments with it on an 11.11 system suggested that
while the -t option is mentioned it is a noop and ping or what it was
using at least, was always setting the TTL to 255.
