Chapter 6: Server Configuration

You’d think that the story of SSH tunneling would end here, but it doesn’t. Subver-

sion allows you to create custom tunnel behaviors in your run-time config file (see

“Runtime Configuration Area.”) For example, suppose you want to use RSH instead

of SSH. In the

[tunnels] section of your config file, simply define it like this:

[tunnels]

rsh = rsh

And now, you can use this new tunnel definition by using a URL schema that

matches the name of your new variable:

svn+rsh://host/path. When using the new

URL schema, the Subversion client will actually be running the command

rsh host

svnserve -t

behind the scenes. If you include a username in the URL (for example,

svn+rsh://username@host/path) the client will also include that in its command (rsh

username@host svnserve -t

.) But you can define new tunneling schemes to be much

more clever than that:

[tunnels]

joessh = $JOESSH /opt/alternate/ssh -p 29934

This example demonstrates a couple of things. First, it shows how to make the Sub-

version client launch a very specific tunneling binary (the one located at /opt/

alternate/ssh) with specific options. In this case, accessing a

svn+joessh:// URL

would invoke the particular SSH binary with

-p 29934 as arguments—useful if you

want the tunnel program to connect to a non-standard ...
