Terminal Command to block certain websites

[DVNIEL]

I've been put in charge with a couple of students at my college to tutor them. There are a few tutorial programs on my Macbook Pro that they need to use, but I wanna make sure that thats all they're doing.

I heard that there are a few terminal commands that you can put in so that certain websites will not be accessible by the browsers. I know I can simply use my admin privileges and remove access to Safari, but I want to give them the freedom to do research on google.

All help would be greatly appreciated. Oh if it means anything, the mainpage I'm trying to block is MySpace =P.

You could use the hosts file to point a given hostname to 127.0.0.1...

Set them up a new account and set up parental controls in system preferences.

If they are in college....treat them like adults and just tell them not to go to that site. If they are there to learn, they will follow your advice....if they aren't, they are only hurting themselves.

Why not desktop remote 3?

Set them up a new account and set up parental controls in system preferences.

This blocks all web sites, and then you (as admin) have to manually log into their account and allow certain ones in Safari.

Apple needs a way of having a blocklist on phrases, addresses or wildcards for accounts.
