I’ve been using TortoiseSVN often, but find myself still needing command-line svn occasionally. The repository I’m working with talks over ssh. Instead of the annoyance of configuring OpenSSH, I used TortoisePlink, part of the TortoiseSVN install.

My Subversion config file is buried in C:\Documents and Settings\robert\Application Data\Subversion\config

I changed the line:

ssh = $SVN_SSH

to: 

ssh = TortoisePlink.exe 

I became happy again.
