SSH Key - Still asking for password and passphrase

Question

I\'ve been somewhat \'putting up\' with Github always asking for my username and password when I clone a repository. I want to bypass this step because it is an annoyance w

Answer 1

I'd like to add an answer for those who may still need to enter the password because they have set IdentitiesOnly as yes. This may cause by multiple keys and the identity file, being keys for git or server.

After I have generated the key and copied it to the server:

ssh-keygen
ssh-copy-id -i ~/.ssh/12gpu_server.pub lerner@192.168.20.160

I found it didn't work.

Then I went to check the ~/.ssh/config file, I saw this at the bottom:

Host *
IdentitiesOnly yes

Then I add this above:

Host 12gpu
HostName 192.168.20.160
User lerner
IdentityFile ~/.ssh/12gpu_server

I can just log in by entering ssh 12gpu.

Then you can add multiple ssh keys using your favorite names, and you only need to add the settings like the above four lines to the config file.

Host is the name you'd like to enter when you connect to the server later; the HostName is the server's ip or domain like github.com; User is the user name you log in the server like the user name or git for github or gitlab; and the IdentityFile is the file where you store the key you have generated.
