You need to use the right private key to access localhost without typing
password or passphrase. In your ~/.ssh/config,
Host localhost
IdentityFile ~/.ssh/id_rsa_phraseless
Host 127.0.0.1
IdentityFile ~/.ssh/id_rsa_phraseless

Well, it is reasonable to have sshd running on a gdb dev box.

Yes, I've added some comments into it.
