RC2 connect with SSH problems

After updating to RC2 of FileZilla 3 Client it will no longer connect when using SSH authentication. Connecting with the same key from the same computer with FileZilla 2 works OK, as did the previous release of FileZilla 3

Here is the connection log:

Sorry, I'll do some more testing on this as it seems to be working on another computer. Maybe that PC was being difficult.

comment:2 by vytautas, 17 years ago

OK, after more checking it seems that FileZilla is no longer using keys stored in the Pageant first or something along those lines, but defaults to trying key files stored in the Putty session settings stored in windows registry.

I fixed this problem by deleting the Putty session data from the registry and then it connected OK on the affected PC.

However I would think that that is not a desirable way/order of reading keys.

This behavior is inherited from the latest PuTTY builds. According to the comments in the PuTTY source, this is by design.
