Hello, everyone. I have noticed that this group gets a lot of requests like the one I'm about to make, but I'm having trouble understanding a lot of it. I would appreciate some help or advice.
Basically, I would like to to monitor our small LAN and be able to tell who is uploading big files via FTP, HTTP, email, etc.
Is there a simple utility that can help me do this? I currently use LinkLogger to monitor traffic requests, which is great because I can tell that 192.168.1.203 does 85% of the web surfing. However, I can't tell if 192.168.1.183 spends all day uploading a few hundred MB of data to an FTP site, because LinkLogger doesn't monitor volume (I don't think). PRTG is another great program I use to monitor internet bandwidth usage. I can definitely see when someone is sending something big, but it doesn't tell me who.
We have a single DSL modem, a LinkSys VPN router, and about 30 devices behind that on a few unmanaged switches.
Thanks for reading to the end. If anyone has any suggestions, I would really appreciate it.
Thanks, Joseph
