Dear List

I would like to monitor the websites which are browsing by my employees. I do have a SOHO environment. WAN IP directly connected to ADSLmodem and LAN connection goes to switch. All the clients are connected to switch. The client PCs are running on Linux and MSWindows. So which software/programme will help me to do this ?

Please help,thanks in advance.

What type of adsl modem do you have?
Some have logging inside them that you can read, and some have filtering as well.

It will need an extra piece of hardware, either a dns proxy or an http proxy.
Each request for a webpage needs a dns lookup, so reading the dns logs can give you the basic domain info.
For detailed url info, you'll need an http proxy like squid, and it will need to sit between the adsl modem and the switch.

The easiest overall is a better adsl modem/router with logging, or a managed switch with logging, or build a proxy yourself. Another option is to build a network sniffer, but I suspect you'll want to block certain traffic in the future, so something that is between the switch and the dsl line will be necessary.

I'd suggest looking into a squid/SARG solution to this problem. It works out fairly well, you will just need to figure out a couple routing issues so that traffic is sent through your squid/SARG box which is possible if you can set all the nodes default gateway to your box, or just configure an interface as the ip of their default gateway.
