How to setup a ssh agent for your access to cvs.apache.org:
with PuTTY on windows
- run puttygen
- select SSH2 DSA (1024)
- click "Generate"
- enter and confirm passphrase
- save private key as "apache-dsa.ppk" (ppk is the default file extension for pageant)
- select all text from the top textbox (Ctrl-A) and save it as "apache-dsa.pub"
- run putty
- ssh into cvs.apache.org using SSH protocol version 2
- add content of "apache-dsa.pub" to "~/.ssh/authorized_keys2" as a single line
- run "pageant.exe apache-dsa.ppk"
- now you will only be asked for the passphrase once you start pageant
- run puttygen
