passwordless SSH

[Soo-Hyun Choi]

Hi,

I'm trying to set up a passwordless environment in my office. What I
did is as follows:

$ ssh-keygen -t rsa
$ cd .ssh
$ cat *.pub >> authorized_keys
$ scp authrozed_keys <my_user_id>@<remote_machine>:./.ssh

Then, if I do ssh, it will keep asking me a passphrase which I set it
during the ssh key generation process.

$ ssh <remote_machine>
Enter passphrase for key '/home/my_id/.ssh/id_rsa':


How do I avoid keep typing the passphrase whenever I do ssh?


Thank you.
