.ssh/config

Host id.github.com
    HostName github.com
    PreferredAuthentications publickey
    IdentityFile ~/.ssh/id_rsa
Host b.github.com
    HostName github.com
    PreferredAuthentications publickey
    IdentityFile ~/.ssh/b_rsa

the question is: when I add ssh key using ssh-add, something seems to be wrong.
