I've generated my ssh key and uploaded it to my github account.

What I do was copy directly my id_rsa.pub to my github account. I've verified the key to my local key using ssh-add -l, it was the same.

Then I try to connect to github using the command: ssh -vT git@github.com I get the following messages:

OpenSSH_5.9p1 Debian-5ubuntu1, OpenSSL 1.0.1 14 Mar 2012

The authenticity of host 'github.com (204.232.175.90)' can't be established.

RSA key fingerprint is 16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48.

Are you sure you want to continue connecting (yes/no)?

I pressed 'enter', then I got the message:

Host key verification failed.

Just for information, I've installed openssh-client. I never succeeded to connect before. Besides, in my .ssh folder, the file known_hosts was never automatically generated. Even if I create manually the empty file, it still doesn't work.

You need to type "yes" when it asks you to verify the host key.

Thanks and sorry for making such a stupid mistake. However I got Permission denied (publickey) now... but I think I can try to search the answer :) –  Y Wang Jul 2 '13 at 7:17

You have to generate an SSH key.

Follow these instructions:

Error: Permission Denied Publickey
