tcptrack Installations.

tcptrack provides a packet sniffer that displays TCP connections similarly to ‘top’.

tcptrack is a packet sniffer, which passively watches for connections on a specified network interface, tracks their states, and lists them in a manner similar to the Unix ‘top’ command.

It displays source and destination addresses and ports, connection state, idle time, and bandwidth usage.


· libpcap 0.7.2 or higher

To build and install:

# ./configure
# make
# make install

To run tcptrack, you need to specify an interface for it to sniff:

# tcptrack -i eth0

You can also provide a pcap filter expression:

# tcptrack -i eth0 src or dst and port 80
