Eclipse, SSH and PuTTY

Yesterday was a great day for me: been accepted as a commiter to AspectWerkz project (thanks again Alex and Jonas, you are just great! - I will write more about this some other time). And now the short story: I got to set up my environment to access CVS using SSH with keys. I think every developer has successfully done this once - this is why I've been a little pissed off. I have generated the keys using ssh-keygen and than another pair with PuTTY. By looking at them I have noticed that they are very differnt. Why this? But let's continue. Finally the PuTTY generated public key was placed on the server and now the long series of tries begun: ssh client (from cygwin) was refusing to connect. Turning verbose mode on (you place up to 3 -v options in the command line) I have found out that indeed the private key was not recognized. I have gone back to using PuTTY and I have successfully logged in. Next step would be having WinCVS and Eclipse connected. In order to shorten the story, I made WinCVS work with Pageant and ssh protocol (i didn't know about it, and I don't think this is correct - as I should use ext or extssh protocol). With Eclipse, I have successfully connected using plink and ext protocol but not with Eclipse SSH support and extssh protocol (probably because of the keys incompatibility, it was failing to connect with an unpleasant/non-explicative message: Auth fail). I would like to find out what I was doing wrong and how I can do the following:

• make WinCVS work with ext or extssh protocol (probably using plink)
• make Eclipse extssh connection work (so not using plink)

A very nice solution for CVS is also TortoiseCVS (thanks Alex for the suggestion. It works nice with pageant). Update: Euxx has posted more hints on Eclipse and CVS usage.
