From local computer A as user a generate a pair of authentication keys. Do not enter a passphrase:
a@A:~$ ssh-keygen -t rsa Generating public/private rsa key pair. Enter file in which to save the key (/home/a/.ssh/id_rsa): Created directory '/home/a/.ssh'. Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /home/a/.ssh/id_rsa. Your public key has been saved in /home/a/.ssh/id_rsa.pub. The key fingerprint is: 3e:4f:05:79:3a:9f:96:7c:3b:ad:e9:58:37:bc:37:e4 a@ACreate a directory ~/.ssh as user b on B.:
a@A:~$ ssh b@B mkdir -p .sshFinally append a's new public key to b@B:.ssh/authorized_keys:
a@A:~$ cat .ssh/id_rsa.pub | ssh b@B 'cat >> .ssh/authorized_keys'That is all
Notes:
.ssh/authorized_keys2.ssh to 700.ssh/authorized_keys2 to 640
