Hi, Am I on drugs, or should: # tcpdump -n -i eth1 not port ssh work? My Red Hat machines like it: $ rpm -q tcpdump tcpdump-3.4-39 But my new gateway doesn't: $ dpkg -s tcpdump | grep ^Version Version: 3.6.2-2 It smells like bug to be, but I wouldn't be too shocked to hear that I was doing something stoopid. Matthew.
