Is there a way to record the connections that my wireless router makes?
Over the last couple of months the total amount of bandwidth used or 
downloaded seems to have increased dramatically without any apparent 
change of use by the three people here who connect to it. So, what I'm 
wondering is this, can I check what connections are being made, 
preferably as a log file so that I can see what's going on.

It's a DG834g and, I can't see anything in it's logs to help me out - 
although I could be looking in the wrong place.

Well yes that might be good. I was kinda hoping for something that would 
do that via the router though...

I googled and found the manual - it looks like it'll only tell you 
exceptional things (port scans, packets dropped) and not what you want. 
You *can* make it use syslog though.

Oh, and there might be SNMP on the router:

<http://mybroadband.co.za/vb/archive/index.php/t-34194.html>

If you can enable it, it *might* give you per-Mac stats. Mostly SNMP 
works at the interface level (eg all traffic on the wireless interface 
is aggregated) so you still might not be able to get what you want.

Really, look into what you can monitor on each Mac.

Cheers,

Chris

Well I've enabled it so I'll have to see what that produces but the 
problem with monitoring the three machines is they are rarely here - 
except for my own - when I am...

It may come to checking the individual machines but it's not an easy one.

Thanks Chris.

Although I'm going to ave a look at these two to see if they can help

Does your router support SNMP? If so, Intermapper is free for up to 5
devices (to be monitored). UI is a little strange, but it can monitor
various parameters (up to you - I even have it monitoring the ambient
air temp at the co-lo). From www.dartware.com.

It supposedly does so I'll have a look at that; thanks Sak.

Hmm, they seem to offer a 14 day trial but no mention that I could see 
of less than 5 devices.

Clearly I haven't been keeping up. But 14 days ought to be long enough
to figure out what's going on.

Should be yes, I've downloaded the package and I'll check the SNMP 
situation this evening and see if I can figure it out.

Apaprently you can email "support@dartware.com" and ask for the "five-
for-free" licence key.

Ah-ha.

Well, I'm just installing now so I'll give it a try with the Free Trial 
setting and see how things get on. Handy to know that they'll supply a 
license key though.
