Yep. The operating system would have been nice but it looks like W2K
or XP from your news header.
The problem with all the IDS (intrusion detection system) that I
listed is that they sniff traffic at layer 3 (IP layer) which assumes
that the wireless client has successfully associated, authenticated,
and has a useful IP address. However, you want to monitor even
unsuccessful attempts and failed associations. That has to be done
inside the wireless access point section at layer 2 (MAC layer). That
can be done, but I'm not sure if the WRV54G qualifies. This is
usually done by syslogd, which the WRV54G supports. See:
<http://www.linksysdata.com/ui/WRV54G/2.36/Administration-Log.htm>
You would need a syslog server such as:
<http://www.kiwisyslog.com/kiwi-log-viewer-features-and-benifits/>
(freeware)
The problem is that I don't think the WRV54G logs failed wireless
associations. Looking at the checklist of things that it logs, I
don't see anything related to layer 2 (MAC layer) or wireless in the
list. I guess the only way to find out is to check everything and see
if it logs failed wireless connection attempts.
However, if you can live without this requirement, and only log
successful connections, any of the monitor programs I listed, plus a
mess of ethernet sniffers (e.g. Ethereal or WireShark) will do the
trick.
Incidentally, I once setup a Cisco 1230AG access point with the MAC
filter set to deny connections to all but a few known devices in a big
office building. When I finally looked at the syslog output, it was
several megabloats per day of nothing but failed associations. Every
wireless device set to "connect to any available network" would try
and connect, fail, sometimes move on, sometimes come back later, and
always leave a mess of entries in the log file. I tracked down one
laptop, that was connected and working normally on a wired ethernet
network, but was attempting to connect every 3 minutes via wireless.
Are you sure you really want to do this?
