Ssh-keygen+ssh-copy-id ssh password-free login access under Linux

Environment:

192.168.2.10

192.168.2.11

Implementation: 2.10 SSH without password login to 2.11

In 2.10 ssh to 2.11 machines, a password is required, which makes it inconvenient for some scripts to work because of the need for a password, which requires manual intervention. The previous method is to copy Authorized_keys inside (remember, before), recently found a command ssh-copy-id very convenient:

Operating on the 192.168.2.10 machine

1) ZWF user, cd ~, run: ssh-keygen-t RSA

2) Then take two returns (select default)

3) Run: ssh-copy-id-i. ssh/id_rsa.pub [Email protected]

Note: Because the server modified the SSH port number (you understand!? So this command needs to be modified

Ssh-copy-id '-p2222-i. ssh/id_rsa.pub [email protected] '

Be sure to use a single citation, or you will report an error

( Pseudo-terminal won't is allocated because stdin are not a terminal.

ssh:umask 077; test-d ssh | | mkdir. SSH; Cat >>. Ssh/authorized_keys:name or service not known )

4) Re-enter the ZWF password on the 2.11 machine

At this point, ssh to the 2.11 machine, you do not need a password. There is no need for a password between the SCP. Rsync is not required.

The benefit of this method is that you do not need to modify the/etc/ssh/sshd_config configuration file before I post an article that needs to modify the sshd_config file.
