note that if you did this to me i'd quit !
how do you think you'd feel if you started having all your freedom ripped away. it's not cool
please understand the impact your going to make

Well, you have the right to quit I'd say ;-p From a business perspective it really is not a bad choice to regulate network access provided the company plays by the rules. If they don't then it's like carrying water to the sea anyways. Maybe check a related note on network acceptable user policy.

Im a sys admin for a company who allows some usage of internet for personal usage while not exceeding a limit each day
honestly this is a much better policy and personally how would you feel if the company had such b.s
sorry but i get upset its like me telling you ohh you can drive your car but you cant listen to the radio while you deliver items to customers.

Right, but listening to the radio doesn't have any security implications.

Hell ya ban their asses.
I went round the office other day and removed MSN from machines because they were too busy chatting and not working.

Next week I'm going to block facebook as well ave it

Having a discussion is perfectly fine as long as it is not off-topic. The discussion here doesn't seem to be off-topic to me. Have you tried denying all connections to talk.google.com with Squid?

Well its kinda hard to block google talk considering the chat client is embedded into the web email

Well, if Google Talk requires clients to connect to talk.google.com in order to work, then blocking connections to that address should prevent it from working - regardless of which client they use. That said, if I was the OP I'd be looking at Squid logs during a Google Talk session to see what exactly is going on and stuff.

Are your users getting around the proxy server?

The general process I use to check is to set up a connection myself, monitor the traffic with wireshark and start blocking ports based on that.

Sometimes you'll get the ports blocked and the application switches to plain old port 80 (or port 443). That's when our desktop guys start deploying modified policies (mostly win xp here) that prevent the application from being available.

Hi,

Already blockede talk.google.com..but still the people can access the chat..Any one please help me out blocking google talk and all the chats.....give me the steps..and iam using dansguardian squid proxy server ...
