How to capture packets from multiple host through tcpdump


What is the syntax to capture packets from multiple host through tcpdump

tcpdump ip host host1|host2|host3|host3.

The above command is not working for me.

It depends on where you want to capture the packets too? are you running a pearl script to run it as a process so everything coming off the wire gets captured? you need a file location to get the packets to collect and then you need a script to organise them in a way so you get the date stamp on each packet.

No i am just running it as a command on Redhat box, there is an option to redirect the output to a file by -w, but i want to see the output on console itself.
