I was connecting to one of my Linux servers from my MS Windows workstation using PuTTY (I generated them on MS Windows using one of the PuTTY related tools, I don't remember which parameters I have used while generating the keys). Now I'm trying to connect to the same server from my Ubuntu GNU/Linux workstation. I already have private / public key pairs in my ~/.ssh :
id_rsa
id_rsa.pub
Now in addition to those private / public key pairs that I already have, I also want to add the private / public key pairs for connecting to my Linux server. For PuTTY I had two files that let me successfully connect to my Linux server:
emrePrivate.ppk
emrePublic.pub
I have copied the above files to my ~/.ssh directory. Then I tried to connect to my server using the following command:
$ ssh -v -i /home/emre/.ssh/emrePrivate.ppk [email protected]
But I see that it tries to use wrong public key. Here's the output:

And as you can see it does not accept my passphrase. I have also tried to copy emrePrivate.ppk over to id_rsa and then emrePublic.pub to id_rsa.pub but I still could not connect to my Linux server.
I'm worried especially about these lines:
debug1: Offering public key: [email protected]
debug1: Authentications that can continue: publickey
debug1: Offering public key: /home/emre/.ssh/id_rsa
But I could not find how I can fix this.
Any ideas?
