First, we must delete the file /home/alice/.ssh/authorized_keys on host2 to revert the permission we gave in the previous example.
ANSIBLE SSH COPY ID PASSWORD
However, since we have to provide the password on the command line, this isn’t a secure choice. So, we can achieve our goal using the -p option. Now, let’s check whether we can connect to host2 from host1 using ssh: ssh able to connect to host2 - ssh doesn’t ask for the password this time. ssh-copy-id doesn’t ask for the password during the configuration, therefore, it’s possible to use ssh-copy-id in a script for the configuration of ssh for many hosts. Here, my_secret_password is the password of alice on host2. We also provide the password from the command line using -p my_secret_password. This time, we pass the ssh-copy-id command as the command that will be run by sshpass.
Now, instead of directly using ssh-copy-id, let’s use it together with sshpass: sshpass –p my_secret_password ssh-copy-id INFO: Source of key(s) to be installed: "home/alice/.ssh/id_rsa.pub" In the earlier example, ssh-copy-id had copied our public key into this file.įinally, after logging out of host2 using exit, we try to reconnect from host1 to host2. Then, we delete the file /home/alice/.ssh/authorized_keys on host2. It would be nice to automate the process to use in shell scripts. If we’re the system administrator and want to configure the system for SSH connections without using passwords, then it’s tedious to enter the password manually for each host while using ssh-copy-id. Then, what’s the problem? We may have many remote hosts with the same username and password combination. Therefore, we’re able to successfully log in to host2 from host1 without using passwords. Now, let’s test whether connecting from host1 to host2 asks for the password: ssh time, ssh doesn’t ask for the password. Now try logging into the machine, with: "ssh check to make sure that only the key(s) you wanted were added.Īfter we enter the password of alice on host2, ssh-copy-id informs us that the key was added.
ANSIBLE SSH COPY ID INSTALL
