svn over HTTP proxy [closed]

Question

I'm on laptop (Ubuntu) with a network that use HTTP proxy (only http connections allowed).
When I use svn up for url like 'http://.....' everything is cool (google chrome repository works perfect), but right now I need to svn up from server with 'svn://....' and I see connection refused.
I've set proxy configuration in /etc/subversion/servers but it doesn't help.
Anyone have opinion/solution?

Okay, this topic is somewhat outdated, but as I found it on google and have a solution this might be interesting for someone:

Basically (of course) this is not possible on every http proxy but works on proxies allowing http connect on port 3690. This method is used by http proxies on port 443 to provide a way for secure https connections. If your administrator configures the proxy to open port 3690 for http connect you can setup your local machine to establish a tunnel through the proxy.

I just was in the need to check out some files from svn.openwrt.org within our companies network. An easy solution to create a tunnel is adding the following line to your /etc/hosts

127.0.0.1 svn.openwrt.org

Afterwards, you can use socat to create a tcp tunnel to a local port:

while true; do socat tcp-listen:3690 proxy:proxy.at.your.company:svn.openwrt.org:3690; done

You should execute the command as root. It opens the local port 3690 and on connection creates a tunnel to svn.openwrt.org on the same port.

Just replace the port and server addresses on your own needs.
