Who is chatting on the network and what?

By reju ·
I have a Network of 80 Machines with Ip Range 192.168.0.1 to 192.168.0.254. I have a router which is the default gateway of the network , with Ip 192.168.0.4 and a leased line of 256 KBPS. All my machines use windows 2000 as the OS.My management wants to know who is chatting on the network as a lot of people spend a lot of time chatting and also want to capture the contents of chatting. I wish to have to a tool to capture this data.

The best tool for the job would be a packet capture utility of some type. WinDump is one freeware possibility (you can find it at http://netgroup-serv.polito.it/windump/).

It will take a little education to know what you're looking at, but this could easily accomplish what you need to do.

One challenge you may have is a fully switched network. If so, you'll have to figure out how to span the switches (varies with mfg) or choose your monitoring points to pick up the traffic of interest to you.

You could try using "stealth" software that monitors PCs. This type of software are installed on the workstation and you can specify what to monitor on that workstation. You have have screen captures at certain intervals or keyboard capture or generate logs. Those things are saved on that PC or on network drive without the knowledge of the user. But there are pros and cons on using this method of monitoring.

You could try using packet capture as stated but it limits to what you can see. You can only see text on packets and if those packets are encrypted then you can see nothing.

Another way is to limit the usage of chatting software altogether. You can close all unneccessary ports and services. But things like MSN and Yahoo Messengerare not that easy to stop, so, they still can do quite a lot.

But bear in mind that reading user's stuff like that could mean breach of privacy and could end up in lawsuit if not handled properly.

Before you start doing this I would make sure that a corporate policy is in place that all users are aware of that you may be monitoring their usage and content.
