This is a re-post from my MySpace blog.

After a couple of days of trying I finally figured out how to use stunnel with subversion. Then after I managed to figure it out I decided I would check the mailing lists and the bug tracker. someone already managed to do the same thing. I however found the solution proposed made more noise than was needed. The openssl s_client on my FreeBSD 6.1 machine still outputs noise about the certificates. After trying openssl, I tried ucspi-ssl and couldn’t get it to work, I finally ended up using sst (and netcat). sst can be found in ports/security/sst, for those on FreeBSD.

Here are the configuration settings that I used. (3691 is reserved by IANA for use by “Magaya something” I forget because I don’t run it).

  1. stunnel.conf
    accept  = 3691
    connect = 3690
  2. ~/.subversion/config in the [tunnels] section
    Either you can override the ssh = or create another scheme such as I did (accessed via svn+ssl://)
    ssl = /path/to/home/bin/svnssl
  3. svnssl (new file, remember to chmod to 700 or 755)
    • with openssl
      /path/to/openssl s_client -quiet -port 3691 -host $1
    • with sst (needs netcat as well)
      NOTE: the timeout option (-t) must be set otherwise sst will keep the connection alive forever, 30 seconds should be more than enough.
      /path/to/sst -p 3691 -t 30 -- nc $1 3691
