looking for a proxy server

[av8or]

I'm looking for a general purpose caching proxy server that will run on Linux. I know about squid but it's not a general purpose proxy. It will only do the http protocol. I'm looking for one that will do other protocols such as ftp and others. Any suggestions?

squid is a full featured web proxy.

It does support ftp.

Here is what it says at http://www.squid-cache.org/:

Squid is...

* a full-featured Web proxy cache
* designed to run on Unix systems
* free, open-source software
* the result of many contributions by unpaid (and paid) volunteers

Squid supports...

* proxying and caching of HTTP, FTP, and other URL's
* proxying for SSL
* cache hierarchies
* ICP, HTCP, CARP, Cache Digests
* transparent caching
* WCCP (Squid v2.3 and above)
* extensive access controls
* HTTP server acceleration
* SNMP
* caching of DNS lookups

If you need anything specific that you don't think squid can do, perhaps you could mention them?

Also on the squid-cache website in the user guide it says

What Squid is not
Squid acts only as an HTTP proxy. It is not a general purpose proxy (so it cannot normally take the place of a firewall proxy.

Squid is based on the HTTP/1.1 specification. Squid can only proxy for programs that use this protocol for Internet access. Browsers, for example, use this specification; their primary function is the display of retrieved web data, using the HTTP protocol.

FTP clients, on the other hand, often support proxy servers, but do not communicate with them using the HTTP protocol. These clients will not be able to understand the replies that Squid sends.

Squid is also not a generic proxy, and only handles a small subset of all possible Internet protocols: Quake, News, RealAudio and Video Conferencing will not work through Squid. Squid only supports UDP for inter-cache communication - it does NOT support any client program that uses UDP for it's communication, which excludes many multimedia programs.

What I'm looking for is a replacement for ISA. It keeps crashin'.........

I only know of a few other proxies at http://www.artus.net/~vinny/projects/proxy/ for udp games and the like. Sorry, don't know anything about a proxy to handle ISA. Even a quick google search didn't turn up anything promising.

Sorry I couldn't help more :(

Heres something from a google search

http://www.uni-paderborn.de/Linux/mdw/HOWTO/Firewall-HOWTO.html

Towards the bottom theres instructions on where to download and how to install socks proxy also. Might work for you but as for a full featured replacement for ISA I doubt youll find. Unless you must run a proxy I would suggest scrapping it for a linux/iptables setup and routed connection vs a proxy but I just hate proxies.
