OPT_RTMON Installs a tool that will track changes in routing tables. Primary used for
debugging.
OPT_SOCAT The program “socat” is more or less an enhanced version of the “netcat”
program (Page 224) with more functionality. By using “socat” you may not only es-
tablish or accept various types of network connections, but also sent data to or read
data from UNIX sockets, devices, FIFOs, and so on. In addition sources and desti-
nations of different types may be connected: An example would be a Network server
listening on a TCP port and then writing received data to a local FIFO or read-
ing data from the FIFO and then transmitting it over the network to a client. See
http://www.dest-unreach.org/socat/doc/socat.html for more information and applica-
tion examples.
OPT_TCPDUMP debug
The program tcpdump can watch, interpret and record network traffic. Find more on
this by feeding Google with “tcpdump man“
tcpdump parameter
OPT_WGET http/ftp Client
The program wget can fetch data from web servers in batch mode. More useful is (and
that is why wget is included here) that it can catch redirections to your provider’s own
webserver while establishig a connection to the internet in a simple way i.e. for Freenet.

4.20.2. Hardware Identification
Often you do not know exactly what hardware is in your own computer or which driver you
should use for i.e. your network card or the USB chipset. The hardware itself can help here. It
provides a list of devices in the computer and the associated driver if possible. You can choose
whether the recognition is done at boot (which is recommended before the first installation)
or later when the computer is running, comfortably triggered from the Web interface. The
output might look like this:
