tcpdump is a
network sniffer, or, phrased a
little more elegantly, a network diagnostic program. It is included by
default in all Linux distributions and also exists for other UNIX
derivatives. It is relatively difficult to use, and its output is also
quite hard to read, which gives tcpdump certain disadvantages compared
with sniffers such as Wireshark
that have a graphical interface. Especially for the FritzBox, however,
the advantage lies precisely in this disadvantage, because no X is
installed on the box (unless someone was actually crazy enough to do
that?).
Warning⚓︎
A lot of traffic will use a lot of CPU, even if that traffic isn't
monitored. However, filtering by network adapter helps.
