If I run plink in a cmd window with -N option
C:\Program Files\Putty>plink -v -l user -pw passw -L 3690:1.2.3.4:3690 mydomain.com -N
the remote svn repository (svn://127.0.0.1) can be accessed with TortoiseSVN and Subclipse
Put the following in your Subversion config file:
ssh = C:/Program Files/TortoiseSVN/bin/Tortoiseplink.exe -v -l user -pw passw -L 3690:1.2.3.4:3690 mydomain.com
the remote svn repository (svn+ssh://127.0.0.1) cannot be accessed from TortoiseSVN or Subclipse
Putty Fatal Error

TortoiseSVN Error
