Description

This is mostly here for Freshmeat ;)<br />
arpdetect is a perl script to detect when the network you're connected to
changes, and run some commands when that happens. It does this by detecting
a MAC address of some host you specify (usually a router). Actions can be
re-run at a predetermined period (reaction).<br />

History

I needed something that detected when I was on a new network and did some stuff.
Like, if I was at work, I wanted to rsync some pictures to my server there, or
if I was at home, I wanted to backup my mail. Things like that. I figured
the easiest way was to arping for a box I knew would always be there (like the
router) and run commands at that time. Of course, you may need to re-run these
commands every once and a while, so it has that support as well. Take it for a
spin, let me know what you think.<br />

Function

Install should be pretty easy; download and install the perl modules required:<br />
Getopt::Long<br />
XML::Simple<br />
Proc::Daemon<br />
<br />
and copy the program to where you like it to be (I recommend
'/usr/local/bin'). Config the thing to do stuff the way you like it in some
config file (I like putting it in '/usr/local/etc/arpdetect.xml') and run it!
You can do that w/ the included init.d script for RedHat, or by typing a command
similar to the following:<br />
/usr/local/bin/arpdetect -c /usr/local/etc/arpdetect.xml<br />
If something's not quite what you expect, or need something else, or it just
plain works, let me know!<br />
