SSH and rsync through a socks proxy

I’ve been using Dropbox for quite some time to transfer files from work to my home PCs. This is worked well for months, but I finally filled my dropbox account.

I looked at using unison, which I used to mirror many other directories but I couldnt get it to connect out from my work PC.   It appears to lack socks support.  I know I could use ssh port forwarding to sync via sockets but this would be more complicated.

I decided to use rsync

via ssh.

There was one main issue though, I needed to get ssh to work over our proxies.  We have a few http proxies and 1 socks proxy.  The http proxies will not connect to arbitrary ports so I ended up using the socks server.

I knew the socks server worked as I’ve used it with putty watch hannah montana the movie online for years, so I just needed to figure out how to setup ssh to use it.

After lots of search and finding articles regarding port forwarding and nothing about using a socks proxy I found 1 good article.

I use gentoo linux so I emerged net-misc/connect which supports socks servers.

emerge -auv net-misc/connect

Once I had the connect utility installed I needed to edit my ssh config file.  I only have 1 user configured on my linux box at work so I edited the ~/.ssh/config file.

This is what I added

Host stokebloke.com
ProxyCommand connect -S user@socks-server:1080 %h %p

Host www.stokebloke.com
ProxyCommand connect -S user@socks-server:1080 %h %p

Host homebox.homelinux.net
ProxyCommand connect -S user@socks-server:1080 %h %p

You can also do the same thing with cygwin too.  Instead of using connect program its called connect-proxy in the network section of the cygwin installer.

After I got this far I needed to configure rsync to work via this ssh connection which, it turns out, is very simple.

rsync --progress -avrz -e ssh src_dir/ user@homebox.homelinux.net:~/dest_dir/

This results in the src_dir existing inside the dest_dir.
