SSH cannot authenticate to [email protected]

Question

Recently, I sign up for a free plan on Github.com. I follow their instructions to generate a ssh key to add to my account. However, when I try ssh -v [email protected], I get this error:

debug1: Server accepts key: pkalg ssh-rsa blen 277
Agent admitted failure to sign using the key.
debug1: Trying private key: /home/phuongnd08/.ssh/identity
debug1: Trying private key: /home/phuongnd08/.ssh/id_dsa
debug1: No more authentication methods to try.
Permission denied (publickey).

When I look into the error, I see a funny thing here, that is the .ssh/id_rsa was not tried, just .ssh/identity and .ssh/id_dsa were tried.

How can I fix this error? Thanks

Answer 1

Check the file permissions on your key. If they are too liberal it may be refusing to use the key. Make sure they only have perssion for you (0700).

Answer 2

you can use ssh-add ~/.ssh/id_rsa to fix this
