Git and ssh authorizating

Question

I can't login to github with generated ssh-keys. I've followed this manual: http://help.github.com/linux-key-setup but at step:

ssh [email protected]

I get:

Agent admitted failure to sign using the key. Permission denied (publickey).

What's wroing? And, of course, I'm adding my own user email.

Tried dsa-key, the same thing.

This issue occurs mainly due to the following reasons :

• The public and private key pair is wrong. You have to verify the key public key on the server/ your git account where you have placed the public key. Even a small space or tab will result in the error.

• If you are sure your public key is correct, then check the format of public key in your ~/.ssh folder in your machine. For openssh you cannot use a public key in puttygen format and visa-versa. To change the format you can use the following command using your private key

  $ ssh-keygen -e -f ~/.ssh/id_rsa > ~/.ssh/id_rsa_com.pub
  $ ssh-keygen -i -f ~/.ssh/id_rsa_com.pub > ~/.ssh/id_rsa.pub

• Finally check if you have added your keys to the ssh client in your system. You can do so by using the following commands

  $ eval "$(ssh-agent -s)"

  $ ssh-add
