Both "net 192.168.0.1 mask 255.255.255.0" (any 192.168.0.x) and "net 192.168.0.1/24" (also any 192.168.0.x) gives an error.
**FATAL_ERROR** Wrong filter 'net 192.168.0.1 mask 255.255.255.0' (non-network bits set in "192.168.0.1 mask 255.255.255.0") on interface eth1
**FATAL_ERROR** Wrong filter 'net 192.168.0.1/24' (non-network bits set in "192.168.0.1/24") on interface eth1
According to http://www.tcpdump.org/lists/workers/2004/12/msg00056.html it's a warning/notice and not really an error.
I'm using 3.2 (it's part of Debian):
