Here are some information to configure wincvs to access the cvs.superwaba.net server through the "ext" protocol requiring a configured SSH access.

First download the latest wincvs win32 setup.

Insofar putty is not really easy to setup, i recommend to use the win32 openssh port.

Follow the instructions in the WinCVS-SSH-Guide_pdf document.

To summarize this very nice documentation:

set your HOME environment variable

to define the place where the key generator will store the keys in a .ssh subfolder. 

set HOME="D:\Documents and Settings\Frank"

create your SSH key

on your local machine by executing 

D:\Documents and Settings\Frank>ssh-keygen -b 1024 -t dsa
Generating public/private dsa key pair.
Enter file in which to save the key (/home/Frank/.ssh/id_dsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/Frank/.ssh/id_dsa.
Your public key has been saved in /home/Frank/.ssh/id_dsa.pub.
The key fingerprint is:

(The document forgot the now mandatory type option.) The following files are generated:

  • "D:\Documents and Settings\Frank\.ssh\id_dsa" => private key
  • "D:\Documents and Settings\Frank\.ssh\id_dsa.pub" => public key

login to your gforge account

and select the "account maintenance" tab and press the edit keys button in the screen bottom.

cut/paste your public key

(the WHOLE content of %HOME%/.ssh/id_dsa.pub without the linebreaks! IMPORTANT) in the editbox, then press update. My public key is:

ssh-dss AAAAB3NzaC1kc3MAAACBALw9c1YskM6sfEiaL6MDxJxsty3SET+F6C6tXafzsB9uywzOm+/gngKQMsqeLxmRMB3jMz4x7tFsiKHefQePv/z

g3ucBm41Rm5M2MT1MBeLIIMi/RS8CUtyFFTFjRCAQqvs= Frank@provider.fr

wait until next quarter

(ssh keys synchronization is done every hour at 00, 15, 30 and 45 minutes)

try your ssh connection

by typing "ssh @cvs.superwaba.net -v" (-v means verbose) 

D:\Documents and Settings\Frank\.ssh>ssh frank@cvs.superwaba.net -v

Securely connected! without entering any password...
However you have to secure your private key.
Hint: If you are paranoiac, store your private key on your USB key you always keep with you wink

Start wincvs

and select "Admin/Preferences", then click the General tab and enter the CVSROOT information to access the CVS repository you want to work on. For instance, here are the information for the SuperWabaSDK cvs repository 

Authentication: ssh
Path: /cvsroot/superwaba
Host: cvs.superwaba.net
User: frank

Select the CVS tab and define the HOME folder, the folder you set at the beginning and that contains the ".ssh" folder containing your associated private key.

For troubleshouting, you may enable the "show CVS console" checkbox.

Checkout a CVS module

by selecting "Remote/Checkout module". Press the three dots "..." to get the list of available modules.

Good luck!
