This command will save all packets going in/out from the host 192.168.5.150 and save it to a dump file in the temporary directory. The above command will capture all 65535 bytes of the packets flowing in/out of the router and save it to a file called dump in the /tmp directory… by default, TCPDump only captures 96 bytes which isn’t very useful when you need to analyse the contents of the packets in Wireshark or similar. The -D will list all interfaces on the router… you can capture packets from a particular interface in future commands by using the -i switch

Note: If you run in to File not found errors, these are most likely due to not being enough free space on the JFFS storage. You will need a SSH/Telnet session configured and open.You will need to enable JFFS2 Support – this can be found on the Administration –> Management page.I got TCPDump working on my WRT-54GL v1.1 box running the recommended firmware build (as of this post) 14929 std-nokaid.There are a few requirements before you go ahead and install TCPDump… of which are listed below.

It’s a bit like Wireshark except it is command line based and in this tutorial, we will be installing it on a router and not on a PC. TCPDump is a command line packet analyser.

This article will serve as a quick tutorial on installing TCPDump on a LinkSys WRT54GL box running the custom DD-WRT firmware.
