Hi Stuart!

!icmp.resp_in and !icmp.resp_to

There might be an easier way :)

Subject: [Wireshark-users] finding a missing ICMP Echo Reply

I have a trace tracking one station pinging another, across multiple
days:  32,371 frames

10.1.2.3    10.1.2.4    ICMP    Echo (ping) request
10.1.2.4    10.1.2.3    ICMP    Echo (ping) reply
10.1.2.3    10.1.2.4    ICMP    Echo (ping) request
10.1.2.4    10.1.2.3    ICMP    Echo (ping) reply
[...]

Somewhere in there is one missing ICMP Echo Reply

I want to find precisely where (when) this occurs.

Can you think of a Wireshark way to accomplish this?

[If not, then I'll write a little code to walk through a text version of the trace, looking for two back-to-back 'Echo (ping) request' lines ... 
but I'm hoping for something slightly faster.]
