I was setting up ssh for git following this guide. I used the key before on another system successfully, expecting it to work now too I tested it with:
ssh -v -T firstname.lastname@example.org
And received the following:
OpenSSH_6.4, OpenSSL 1.0.1e-fips 11 Feb 2013 debug1: Reading configuration data /etc/ssh/ssh_config debug1: /etc/ssh/ssh_config line 51: Applying options for * debug1: Connecting to github.com [188.8.131.52] port 22. debug1: Connection established. debug1: identity file /home/user/.ssh/id_rsa type 1 debug1: identity file /home/user/.ssh/id_rsa-cert type -1 debug1: identity file /home/user/.ssh/id_dsa type -1 debug1: identity file /home/user/.ssh/id_dsa-cert type -1 debug1: identity file /home/user/.ssh/id_ecdsa type -1 debug1: identity file /home/user/.ssh/id_ecdsa-cert type -1 debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_6.4 debug1: Remote protocol version 2.0, remote software version libssh-0.6.0 debug1: no match: libssh-0.6.0 debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: server->client aes128-ctr hmac-sha1 none debug1: kex: client->server aes128-ctr hmac-sha1 none debug1: sending SSH2_MSG_KEX_ECDH_INIT debug1: expecting SSH2_MSG_KEX_ECDH_REPLY debug1: Server host key: RSA 16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48 debug1: Host 'github.com' is known and matches the RSA host key. debug1: Found key in /home/user/.ssh/known_hosts:1 debug1: ssh_rsa_verify: signature correct debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: Roaming not allowed by server 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 RSA public key: /home/user/.ssh/id_rsa debug1: Authentications that can continue: publickey debug1: Trying private key: /home/user/.ssh/id_dsa debug1: Trying private key: /home/user/.ssh/id_ecdsa debug1: No more authentication methods to try. Permission denied (publickey).
Apart from the obvious
Permission denied (publickey), it looks like ssh could not distinguish between the private key
id_rsa and the public one
id_rsa.pub. Which are both in
So did I just send my private key to email@example.com?
What I already tried:
#Create new public key ssh-keygen -y -f ~/.ssh/id_rsa > ~/ssh/id_rsa.pub #id was added ssh-add -l 2048 ==numbers== home/user/.ssh/id_rsa (RSA) #Check the permissions ls -l ~/.ssh -rw-------. 1 user user 1675 Sep 3 09:53 id_rsa -rw-r--r--. 1 user user 381 Jan 23 09:21 id_rsa.pub -rw-r--r--. 1 user user 1371 Jan 23 09:30 known_hosts #Take a look at /etc/ssh/ssh_conf Host * GSSAPIAuthentication yes ForwardX11Trusted yes SendEnv LANG LC_CTYPE LC_NUMERIC LC_TIME LC_COLLATE LC_MONETARY LC_MESSAGES SendEnv LC_PAPER LC_NAME LC_ADDRESS LC_TELEPHONE LC_MEASUREMENT SendEnv LC_IDENTIFICATION LC_ALL LANGUAGE SendEnv XMODIFIERS ServerAliveInterval 300 ServerAliveCountMax 2 #Looks alright to me...
