Using Redhat as a proxy server 1

[da644]

Hi.

I've set up a Linux server using Redhat 7.2 and have it configured just the way we want to use it as a file server. We would now like to also use it as a proxy server to give the other windows computers on the network Internet access. Does Redhat have a proxy with it by default or will I have to download one??? In both cases, where can I find it???

Thanks

Best Regards

Andrew

You may already have installed (as part of your RH install) the proxy server SQUID... to find out, type
rpm -qa|grep -i squid

If not, you can install it from your CDs (CD #1 if I recall)...

Squid can be fun to configure....so dont forget to check

http://www.squid-cache.org

for more info

Hi,

A slight word of warning on squid - it is limited to proxying http protocol only so, for most people, its not a 100% answer to sharing an internet connection. On M$/Poxy server, for example, you have the wsp option where everything that isn't in the lat is remoted. Squid just does http and ftp via a browser but not from a regular ftp client. Latest squid is ftp://rpmfind.net/linux/redhat/updates/7.2/en/os/i386/squid-2.4.STABLE1-6.i386.rpm which is an update from the original that shipped with 7.2 . Just download that somewhere and install/upgrade as root with :

rpm -Uvh squid*.rpm

For other things, you have to employ IP masquerading (special form of source network address translation) using iptables.

Yeah, you definitely will want to look at iptables as it handles not just firewalling, but NAT and DNAT (Port forwarding).

What you say? Check out this developer works tutorial, it will walk you setting up a firewall, NAT (Internet connection sharing) and more. Also check out Rusty's unreliable guides...
