I just created a new capture, this time with icmp:

        tcpdump -nvvv icmp or \( tcp port ssh
                and not tcp src port 60227
                and not tcp dst port 60227
                and not tcp src port 60178
                and not tcp dst port 60178 \)

60227 and 60178 were used by two interactive sessions.

Unfortunately, there is no ICMP in the capture except the first two
packets which were sent by me in order to test the filter expression:
