RE: [squid-users] SQUID behind SOCKS5

I cant really put SQUID up after SSH their either.

The server has access to the internet to do SSH. But the server has a firewall on it that disallows any access from it to anything but the SSH (and SOCKS which actually runs over the SSH).

The basic idea is this - everything from the location MUST go out over the SSH/SOCKS connection. Nothing else is permitted, so the only traffic that goes on its normal internet connection is the SSH tunnel.

All clients on the LAN then use proxies made available by the server which right now are tunneled ports and a SOCKS5 connection. Actually there is also a HTTP proxy on the other side of the SSH which we open a tunnel to as well, but its not configured well and interferes with web services etc.

We cannot change/alter/install things on the SSH server side.

The SOCKS and SSH work really well, but we just need to make a local HTTP proxy which can take local requests from the LAN but makes its requests over the SOCKS. This will bridge the gap between the apps which don’t support SOCKS directly but do support a HTTP proxy.

Privoxy can actually do this but it doesn’t support PUT and some other advanced HTTP commands so it also fails with many of the web clients.

We have a local DNS server which chains to another upline one on the SSH server side so if we can just get the HTTP requests over SOCKS SQUID can use our local DNS and it will take care of the rest.

So if nothing else appears... maybe I'll have to go digging...

How hard is it to get SQUID to build on Windows?
