can you explain the steps you took to set this up. and what ssh client are you using on the windows side?

I generated the key on windows:
ssh-keygen -t rsa

copied the key to the Linux box.

formatted the key and concatenated it to authorized_keys:

ssh-keygen -e -f id_rsa.sfvmvcs1 >> authorized_keys

Re: Can't ssh from windows to Linux with ssh keys in place

I am assuming that the file id_rsa.sfvmvcs1 is your public key. If it isn't that could be a problem. ssh-keygen should have created a file called is_rsa.pub which would be the public file. Moving on, I really do not think that you needed to export the file to IETF SECSH. try just cat'ing your pub key to .ssh/authorized_keys.

You could also try just removing the lines

---- BEGIN SSH2 PUBLIC KEY ----
---- END SSH2 PUBLIC KEY ----

Re: Can't ssh from windows to Linux with ssh keys in place

Alexander Fedyashov — Fri, 20 Jul 2007 15:36:38 GMT

Yes, it is the public key.

The windows key on the Linux host looks something like this:

---- BEGIN SSH2 PUBLIC KEY ----
Comment: "1024-bit RSA, converted from OpenSSH "

thanks,
Alex

just remove the lines you added and just add the pub key as is.

cat id_rsa.sfvmvcs1 >> .ssh/authorized_keys

Re: Can't ssh from windows to Linux with ssh keys in place

Alexander Fedyashov — Fri, 20 Jul 2007 15:47:39 GMT

I didn't add any lines.

Thanks .... at first I didn't know what you meant, but it's working now. I guess I was never supposed to reformat the key for Linux?
