Configuring Squid as a Linux Proxy Server?

We use Squid at work. As to the AdZapper thing, we incorporate the HOSTS file at:

http://www.mvps.org/winhelp2002/hosts.htm

as one filter set. Nice thing is a lot of those entries at MVPS are known spyware sites, which saves the IT folk later headaches if we block them to begin with.

The file gets updated regularly. But it doesn't quite match Squid's config files, so I did a simple script to convert it for Squid use.

We keep a whitelist that compares against the MVPS list. Those guys block some sites (certain Overture domains, for example) that our marketing department actually needs to visit. With the whitelist we can largely automate the benefits of the MVPS file without hampering legit usage.

I am working as a Network Administrator at the University of the Gambia.. We ahve a new server and I want to install Linux as a both internet and file server, and host our own website but i have no idea on linux... we have 64 PCs

Squid's own squidguard can block ads, among other things (except ultraviolet rays). No need for a separate program.

I am working with SCMLD.Pune. we have 110 desktop and three server. two is windows 2000 & one is Linux but i have to configure squid & sendmail on linux 9.0 ver. Please late me know How i am going to configure this two option.
Thank You.

ok i want to know how to use a proxy at school if it's blocked... i used to use it all the time but the school caught on and now i want a way to be able to go to blocked sites without having to download anything or having to take hours just to get somewhere.. can you help me?

Bob, dare I say it: maybe you need to just live within the rules at school rather than keep trying to find ways to circumvent it?

Squid Server configuration

Squid uses the configuration file squid.conf. It is usually located in the /etc/squid directory. Access through the proxy can be given by individual IP addresses or by a subnet of IP addresses.
In squid.conf search for the default access control lists(acl) and add the following line below them:
acl mynetwork src 192.168.1.0/255.255.255.0 (for subnet)
acl mynetwork src 192.168.1.10/255.255.255.0 (for individual IP)

Then add the access control list named "mynetwork" to the http_access list with the following line:
http_access allow mynetwork

The default port for the proxy is 3128. Uncomment the following line and replace 3128 with the desired port :

http_port 3128

After configuration Restart this service

Assuming you have the runlevel scripts installed you can use the following commands as root:

Start squid /etc/rc.d/init.d/squid start
Restart squid /etc/rc.d/init.d/squid restart
Stop squid /etc/rc.d/init.d/squid stop

or issue the following TWO commands as root:
squid -z
squid

or configure squid to start at boot time using your runlevels.

troubleshooting: [do this on the proxy server]

'tail -f /var/log/messages' in a seperate bash window while restarting squid
'tail -f /var/log/squid /access.log' in a seperate bash window while
attempting connections to the proxy server. watch the output for
success & failure.

Hello,

All you need is to install CentOS, Fedora or any new version of Linux,
Linux comes with Squid, choose that when you install , mostly squid is auto selected.
After you have configured your Linux box, go to :
#
# cd /etc/squid/
# more squid.conf
squid usually configures itself on port 3128
before anything is process under squid it look at two files.
restricted-sites.squid and allowed-sites.squid,
these are the two files where whatever you put as .domain.com is allowed under allowed-sites.squid and restricted under restricted-sites.squid
after you are done adding the domains. for e.g
if you want to allow website www.google.com then
# vi allowed-sites.squid
.google.com
save the file and you are good.
after you are done adding the website use:
# squid start or look at the above command on this page.

I used Microsoft Active Directory to automatically deploy proxy server on IE or do it manually on IE and limit access control to change IE settings.

cheers

I am running squid as a proxy on a server outside the firewall to serve up web pages. The proxy and web server are running windows and the service on the web server is Apache. The problem is no matter what I do I can not get squid to serve up a web page. Im not getting any errors in the logs. I do get the error page from squid then I type the URL into the browser ( Im running squid in transparency mode so the user need no browser configuration )Any ideas?
