8 Monitoring the interface
Wireshark is a free analysis program for network communication connections. It
allows you to:
– Show data traffic across an Ethernet interface after or during capture in the
form of data packets,
– observe individually captured data packets,
– sort data packets according to specific contents,
– extract binary contents (e.g. images),
– create and work-up data flow statistics.
The free program library "WinPcap" permits the transparent capture of data traffic
under Microsoft Windows®.
You can use Wireshark on most standard systems. To analyze additional
information, however, we currently offer a plugin only for Windows.
