Block MSN with Squid

You can block a few sites with squid by
either adding them to squid.conf or creating
another file containing a list of restricted
sites.

Editing /etc/squid/squid.conf; add lines
similar to the following:
acl msn url_regex messenger.hotmail.com
http_access deny msn
That should deny all access to
messenger.hotmail.com which is what MSN
uses.

Creating an ACL list; create a file
called /etc/squid/squid-block.acl and put in
it what you want to deny access to, eg:
messenger.hotmail.com
.msn.com
microsoft
The above will deny access to
messenger.hotmail.com, anything..msn.com and
any URL with microsoft in it. Then in your
squid.conf file:
acl bad url_regex
"/etc/squid/squid-block.acl"
http_access deny bad
NB If you start blocking sites with words
like "sex" in them you may have to create
another file of accepted URLs like
www.middleSEXuniversity.edu.uk.

PS The above methods will only work if your
users are using MSN through your proxy. If
they are going straight out through a
gateway you will have to use firewall rules
instead.
