SSH no password rsa-key RHEL 5


SSH no password rsa-key RHEL



1) On the machine you are trying to access open a terminal and
(Skip these step if you never generated a key before and or you want a fresh start)

a) As root backup .ssh directory for the user by moving it to ssh.backup

# mv /home/user/.ssh/ ssh.backup

2) On the machine that we will generate the RSA-Key open a terminal and
(Skip these step if you never generated a key before and or you want a fresh start)

a) As root backup .ssh directory for the user by moving it to ssh.backup

# mv /home/user/.ssh/ ssh.backup

3)On the machine that we will generate the RSA-Key open a terminal and

a) Create the RSA key as the user you want to access the remote machine

# ssh-keygen

b) Press enter to accept defaults

Generating public/private rsa key pair.
Enter file in which to save the key (/home/manuken/.ssh/id_rsa):
Created directory '/home/manuken/.ssh'.

c)Press enter leave the passphrase blank

Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/manuken/.ssh/id_rsa.
Your public key has been saved in /home/manuken/.ssh/id_rsa.pub.
The key fingerprint is:
8a:8f:d3:9e:db:d5:93:b7:c4:fd:d8:0a:21:e1:47:91 manuken@manuken-laptop.lan

4) Now copy the key to the remote machine .


# ssh-copy-id -i $HOME/.ssh/id_rsa.pub user@remotehost

5) ssh in to the machine you should be able to access without a password.
