Ban certain sites.

[funtoosh]

I want to ban certain sites so that they are not displayed when someone requests them. How this can be done.

Blocking the hostname would do it for the most ,but some of them don't configure the reverse dns.In such cases you might have to block by IP instead of blocking by their hostnames , but even blocking IPs through firewalls have some cons.So you could use both depending on the sites you want to block.

I have a wireless router and rest all clients connect through there wifi cards.

There are various applications and also you can find the IP of the site and ban it manually.

Make sure your user account to log onto the computer is set as the System administrator.Then on the administrator tools you can manage your account and others so some sites are blocked which you request.
