To use tcpdump on an iDirect modem, first, ensure you have access to the command line interface. Connect to the modem via SSH and run the command tcpdump -i <interface>, replacing <interface> with the appropriate network interface name (e.g., eth0). You can add options like -w to write the output to a file or -nn to prevent DNS resolution. To view live traffic, you can simply execute tcpdump without any options, but be cautious as it can generate a large amount of output.

No, TCP/IP is the not the only protocol used in the world, but it is certainly one of the most popular. Older networks may still use IPX/SPX (Novell) which is a competitor to TCP/IP.
