| Well, that depends on what you consider remote. Sveasoft Alchemy does
| PPTP VPN (or IPSec if compiled from source) which can act as a remote
| VPN tunnel over the internet to your remote computah. It's like you
| were on the local LAN, with local LAN IP addresses, but running over
| the internet. Just about anything you can do on the local LAN at the
| router, you can do remotely through a VPN tunnel. Methinks running
| AirSnare through a VPN tunnel will work. I can try it if you want,
| but I'm kinda busy/lazy/burned-out/irate/bummed/etc this week.
|
| If you wanna do "real" remote monitoring, look into enabling syslog on
| the WRT54G and point it to your remote computah. Run a syslog server
| (there are numerous syslog servers for every operating system) and use
| one of the numerous syslog report writers to extract the data or
| detect changes. If you wanna do it crudely, try running Linux
| "arpwatch" which will detect new MAC addresses on the LAN.
|
| If you're really into this, you can also use SNMP to monitor the MAC
| addresses on the wireless port. Sveasoft Alchemy does SNMP. Dig out
| one of the numerous SNMPwalk utilities to dump the part of the MIB
| tree with the MAC address, and scribble your own script to detect
| changes.

Thanks,
Rant (good points none the less) reply. I'm doing (free) tech support for
a group of non profits and their clients. I'm not as sharp at this as most
but in the land of the blind ...
Regardless as I'm in a somewhat remote area (you have to drive 40 miles to
get a traffic ticket -- not joking as the local cops know everyone and will
call your mama or grandma instead of giving you a ticket) anything that I
can find to cut down on the drive time is a significant savings to my
retirement budget. Gas here averages $2.25/ gal. and a long run, especially
if it's urgent, can cost me almost a tank (20 gal). Non urgent support I
try to schedule so that I can make loop. Still a tank of gas but more
people/gal. Yes I could ask them to pay the fuel but it might come down to
my fuel or helping someone who needs it more than I do and that's not
something I'm comfortable with.
As to the hardware/software it's scattered all over the place as most comes
from donations of older equipment and software (some comes via TechSoup
www.techsoup.org )
Thanks for the help sorry for being so short on the background info.
How can I determine source of wireless activity?
