ttt

ttt(1)									net								    ttt(1)

NAME

       ttt - Tele Traffic Tapper - a standalone program for local, real-time, graphical traffic-monitoring.

SYNTAX

       ttt [-interface device] [-interval ms] [-dumpfile file [-speed N]] [-yscale (K|M|n)]

DESCRIPTION

       ttt is the standalone traffic monitor program in the ttt program suite. It displays trafic-data of a local interface.

       To run ttt, you must be "root" on most systems since only root is allowed to access the network filter device.

       The  ttt program suite is yet another descendant of tcpdump but it is capable of real-time, graphical, local and remote traffic-monitoring.
       It won't replace tcpdump, rather, it helps you find out what to look into with tcpdump.

OPTIONS

       -interface device
	      specifies the interface for packet capture. If not specified, the default interface is chosen.

       -interval ms
	      Sets the interval in Milliseconds. If omitted, a interval of 1000 msec. is used as default.

       -dumpfile file [-speed N]
	      use a dumpfile (produced by "tcpdump -w") as input. The speed option specifies the acceleration factor of the replay speed.

       -yscale ('K'|'M'|n)
	      change the scale of y-axis. 'K' and 'M' represent 1000 and 1000000 respectively.

EXAMPLES

       To run this program the standard way type:

	      ttt

       To listen only on interface eth0:

	      ttt -interface eth0
