How can I enable password less authentication with SSH.
This is what I have when I was looking for /.ssh folder.
bash-3.00$ cd ~/.ssh
bash-3.00$ pwd
/home/uname/.ssh
bash-3.00$ ls -lt
total 2
-rw-r--r-- 1 uname gid-uname 489 Jul 26 18:55 known_hosts
And I don't know what next I have to do here? I need to change the permission of known_hosts folder? Or something else?
回答1:
Add your public key to a file called authorized_keys.
Make sure that no group and other permissions are not set.

To enable passwordless ssh between remote and local machine, you have to perform these steps on your local machine :-
1st Step> root@localmachine:~> ssh-keygen -t rsa
Note - Considering that .ssh dir is already present in remote machine if not, then do this (ssh root@remotemachine mkdir -p .ssh)
2nd Step> cat .ssh/id_rsa.pub | ssh root@remotemachine 'cat >> .ssh/authorized_keys'
3rd Step> root@localmachine:~> ssh root@remotemachine

- Generate your keys using
ssh-keygen - Copy over your SSH identity to the host (to which you need passwordless login) using
ssh-copy-id.
man ssh-keygen and man ssh-copy-id on your system for help.
