Default Blocking certain web sites

Hi Guys

Just by my name youll resise im clueless hehehe.

I have a problem that i need to see if i can sort out.

We have serverl Pcs at our office and the staff are starting to take the cheese and going onto various websites that i dont think they shoudl be going on.

I need some thing that will block websites that i tell for eg.

Block William Hill Bookmakers

So that the page diverts to a Page not displayed page so that they dont think its down to me.

Can any one help please

hmm , if you are using a router with multiple computers you may be able to add blocked sites to the router , depending on the router make/model

well i dunno much about the workings of the bt home hub , but i am going to presume you go to the ip 192.168.1.1 for settings , i dunno if the home hub has this feature but there should be a internet restrictios or whatever ,
now you need to set the settings for this and there should be a field where you enter blocked IP's

at the mo mine is just doing a timeout i have used google as a test , it seems it just times out as the router is instructed not to send any data to the pc's recieved from www.google.com

Obviously no one here works in an IT enviroment or server room.

For IT professionals This is all you need to filter websites

I might be completely wrong in my theory here. But couldn't he use a vbs file that replaces the user's hosts file every time they login to something like.

127.0.0.1 www.badsite.com
etc....

Don't use proxies. They're old school.

Download Firefox and surf through another proxy. That's what I do, it works like a charm.

Only two problems with your theory

1.) you need to disable cookies in your *web browser* first before configuring it to work with a proxy server.

Also, websites like Public proxy servers from sites like;

http://www.publicproxyservers.com/page1.html


They have a disadvantage. They leak *DNS request* so your not as anoymous as you think you are.

Thats why I would recommend TOR from http://tor.eff.org/download.html.en or even (torpark which can run from a usb key)

and download the bundle which consists of Tor & Privoxy & Vidalia bundle: 0.1.1.26 (sig), 0.1.2.12-rc (sig).
Download it, and save it on your system. Next, run it and install it on your system. After you click 'finish' the white privoxy window will display.

Just a little FYI, Tor uses SSL to encrypt all data, and doesn't even leak DNS requests, unlike some proxy servers. As long as it's configured properly and using an appropriate proxy (such as Privoxy, which comes in the bundle).
TOR *cannot offer 100% total anonmity* so If the connection to the website is not secure (e.g https) then the last gateway will be able to see (and potentially sniff) all traffic.
