[nzlug] Ping/Traceroute issue.. Nagios involved.. VMWareinvolved..

[Michael Hutchinson]

Hi Robin, 

Thanks for your timely reply. Unfortunately mine is rather late :)

I am not willing to install Wireshark on our server bob as it is
considered a production server, and the pre-requisites for Wireshark
would mean installing software that we do not want on there.

By the time I installed Wireshark on the monitored target, the problem
went away again. Do you know of any other program that hasn't got so
many dependencies to fill that could satisfy the inquest of this ping
problem?

I am thinking it may have something to do with netmask's, but am unsure
whether this could affect ping. My knowledge of appropriate netmasks to
use in any given network is a bit limited - but then the same applies to
my peers, and that makes me wonder if there are netmask issues on our
networks that we don't know about.

Cheers,
Mike

What does running wireshark at either end tell you? Are the pings not
getting 
out from the source, are they not reaching the destination, is the 
destination not responding, or are the responses not getting back to the

source? That would at least provide some information on where to start 
looking.
