Hi,

I'm searching for a free home lan monitor tool so I can see the download and upload of each user connected to the network.
Any ideas?
 
Do you just need to see if the computer is active on the network or are you actually trying to spy on content, and if so, why? I mean are you trying to monitor what kids are doing on their computers or something?
 
Nono, it's just I have an internet connection here. And my neighbour has asked me if he could connect to my wireless internet. So I said yea why not. But now I'm starting to have the feeling that he is abusing it and he is downloading A LOT!
So I just want to see the amount of download and upload.
 
Look at your router. Is his light blinking like crazy?

And if push comes to shove, just lock him out.
 
Yeah, I would just turn on MAC Address filtering and lock him out. If he wants internet that bad he can pay for it himself or split the cost with you. I wouldn't mess about, just change your WEP key and enable your MAC address filtering. If he bitches about it just tell him that the situation has changed and you need your bandwidth for yourself because you are launching a server or something, but remind him that he should be thanking you for letting him piggyback your connection free of charge.
 
Unfortunately the only way to really meter the traffic is to have a router that supports SNMP. Your run of the mill home routers aren't likely to have SNMP capabilities (but if you have a linksys with the linux firmware, I believe it adds SNMP support). Your options really are looking at the lights, or putting a linux box between your internet and your network and then using it to measure usage with a program like mrtg. You can also use tools like tc to set limits on connections to certain address ranges.
 
^Haha, imagine that conversation...

"Hey Dude, how are you doing? Cold today, he? Listen, have you been downloading a terrabyte of porn last month? ;.)"
 
most routers show the total gb up and down. just monitor your usage and take that away from the total.

Or you could put a box after the WLAN like you said and use a packet sniffer to check what he is doing :whistle:

Using an app like Wireshark and filtering everything but his IP should do the trick..
