ssh'ing rsync out of proxy hell...

I had a situation last week where I needed to install macports but due to local proxy behaviour I could not get rsync to work.

However I did have ssh working through the proxy, and I had access to an external system which didn't have the proxy issues... so I created a tunnel.

Now this has to be done as root, as it needs to create a listening port below 1024.

First I changed the
/opt/local/etc/macports/sources.conf to point to the localhost
#rsync:// [default] rsync://localhost/release/ports/ [default]

Then I created a tunnel through my external system using ssh
ssh -L

On that ssh connection I did the following to keep that session active:
ping -i 60 localhost

Now macports quite happily rsync'd away oblivious to the plumbing I had to do. Gotta love ssh.
