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 :
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:
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@example.com
But I see that it tries to use wrong public key. Here's the output:
OpenSSH_5.3p1 Debian-3ubuntu4, OpenSSL 0.9.8k 25 Mar 2009 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug1: Connecting to yafz.org [184.108.40.206] port 22. debug1: Connection established. debug1: identity file /home/emre/.ssh/emrePrivate.ppk type -1 debug1: Remote protocol version 2.0, remote software version OpenSSH_5.1p1 Debian-6ubuntu2 debug1: match: OpenSSH_5.1p1 Debian-6ubuntu2 pat OpenSSH* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_5.3p1 Debian-3ubuntu4 debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: server->client aes128-ctr hmac-md5 none debug1: kex: client->server aes128-ctr hmac-md5 none debug1: SSH2_MSG_KEX_DH_GEX_REQUEST(1024<1024<8192) sent debug1: expecting SSH2_MSG_KEX_DH_GEX_GROUP debug1: SSH2_MSG_KEX_DH_GEX_INIT sent debug1: expecting SSH2_MSG_KEX_DH_GEX_REPLY debug1: Host 'yafz.org' is known and matches the RSA host key. debug1: Found key in /home/emre/.ssh/known_hosts:3 debug1: ssh_rsa_verify: signature correct debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: SSH2_MSG_SERVICE_REQUEST sent debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey debug1: Next authentication method: publickey debug1: Offering public key: firstname.lastname@example.org debug1: Authentications that can continue: publickey debug1: Offering public key: /home/emre/.ssh/id_rsa debug1: Authentications that can continue: publickey debug1: Trying private key: /home/emre/.ssh/emrePrivate.ppk debug1: PEM_read_PrivateKey failed debug1: read PEM private key done: type <unknown> Enter passphrase for key '/home/emre/.ssh/emrePrivate.ppk': debug1: PEM_read_PrivateKey failed debug1: read PEM private key done: type <unknown> Enter passphrase for key '/home/emre/.ssh/emrePrivate.ppk':
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@example.com 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.
