I tried to use github so I followed the help doc. But when I used this command :
ssh -vT firstname.lastname@example.org I got error like this:
jacos@Jing:~/.ssh$ ssh -vT email@example.com OpenSSH_5.8p1 Debian-7ubuntu1, OpenSSL 1.0.0e 6 Sep 2011 debug1: Reading configuration data /home/jacos/.ssh/config debug1: Applying options for github.com debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug1: Connecting to ssh.github.com [126.96.36.199] port 443. debug1: Connection established. debug1: identity file /home/jacos/.ssh/id_rsa type 1 debug1: Checking blacklist file /usr/share/ssh/blacklist.RSA-2048 debug1: Checking blacklist file /etc/ssh/blacklist.RSA-2048 debug1: identity file /home/jacos/.ssh/id_rsa-cert type -1 debug1: identity file /home/jacos/.ssh/id_dsa type -1 debug1: identity file /home/jacos/.ssh/id_dsa-cert type -1 debug1: identity file /home/jacos/.ssh/id_ecdsa type -1 debug1: identity file /home/jacos/.ssh/id_ecdsa-cert type -1 debug1: Remote protocol version 2.0, remote software version OpenSSH_5.1p1 Debian-5github2 debug1: match: OpenSSH_5.1p1 Debian-5github2 pat OpenSSH* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_5.8p1 Debian-7ubuntu1 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: Server host key: RSA 16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48 debug1: Host '[ssh.github.com]:443' is known and matches the RSA host key. debug1: Found key in /home/jacos/.ssh/known_hosts:4 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/jacos/.ssh/id_rsa debug1: Remote: Forced command: gerve gnijuohz 54:da:c2:c1:ca:4a:b9:4d:21:10:5b:42:3f:5a:8e:f7 debug1: Remote: Port forwarding disabled. debug1: Remote: X11 forwarding disabled. debug1: Remote: Agent forwarding disabled. debug1: Remote: Pty allocation disabled. debug1: Server accepts key: pkalg ssh-rsa blen 279 Agent admitted failure to sign using the key. debug1: Trying private key: /home/jacos/.ssh/id_dsa debug1: Trying private key: /home/jacos/.ssh/id_ecdsa debug1: No more authentication methods to try.

Agent admitted to sign using the key? No more authentication methods to try?
Can someone explain what's wrong here?
