>Description:
From tcpdump man page:
To print all ICMP packets that are not echo
requests/replies (i.e., not ping packets):
tcpdump 'icmp[0] != 8 and icmp[0] != 0"
^^^ ^^^
>How-To-Repeat:
man tcpdump
Try to follow the example:
rafraf# tcpdump 'icmp[0] != 8 and icmp[0] != 0"
Unmatched '.
Make sure both are " ' "
rafraf# tcpdump 'icmp[0] != 8 and icmp[0] != 0'
tcpdump: listening on xl0
21:54:43.368414 192.168.1.100 > rafraf: icmp: time exceeded in-transit [tos 0xc0]
21:54:43.424888 192.168.1.100 > rafraf: icmp: time exceeded in-transit [tos 0xc0]
>Fix:
Change
tcpdump 'icmp[0] != 8 and icmp[0] != 0"
to
tcpdump 'icmp[0] != 8 and icmp[0] != 0'
