Re: proxy to restrict the client systems from downloading anything from internet

In comp.os.linux.security smart <satyaprakash82@xxxxxxxxx>:
hi,im new to system admin.can anyone tell me what proxy can i use to
restrict my client systems from downloading anything from internet.i
need this because my management wants to speedup the internet by
restricting the users from downloading anything from internet.but it
should not restrict them from browsing or surfing.

You need to ensure at first that all client are forced to use the
proxy to make any further control possible. This can be done via
forcing transparent proxy. Squid can be used as proxy and has
various ways to restrict client speed/download, like delay pools
which work pretty well. Check the squid FAQ, just use Google for
what it was intended to do.

There are even more restrictive ways if you add squidguard or
dansguard to your proxy. However I'd just run squid in
transparent proxy mode for some time and then check the cache
manager statistics. Perhaps only using squid can speed up
internet pretty much for your users without restricting anything.

Comes with most distro per default:

http://www.squid-cache.org/

Good luck
