tcpdump: Monitor ALL eth1 Traffic Except My Own SSH Session
I'm using tcpdump to dump, debug and monitor traffic on a network. However, there is lots of noise and I would like to exclude ssh from my dumps. How do I monitor all traffic except my ssh session?
The tcpdump command displays out the headers of packets on a network interface that match the boolean expression. In other words you can use boolean expression to drop ssh traffic from dumping and monitoring operation using the following syntax:tcpdump -i eth1 -s 1500 port not 22You can skip additional ports too:
tcpdump -i eth1 -s 1500 port not 22 and port not 53You can also use ip or hostname:
tcpdump -i eth1 port not 22 and host 1.2.3.4See also:
man tcpdump
