This guide goes through setting up SSH keys on macOS Mojave 10.14 back to Mac OSX 10.11 and also a secure password-less SSH connection between a local macOS workstation and a remote server also running a Linux variant operating system.
The process requires generating a public and private key on the local computer and then adding the public key to the remote servers authorised list. What is great about this is that it allows a password prompt free session, handy for a lot of uses.
- Dec 03, 2017 Use this command in Terminal to remove Java 9.X from your Mac. Let’s generate ssh key for that account and assign it to our Jenkins user. Whoami # make sure it says 'jenkins' ssh -T git.
- Create an SSH key. Follow these steps if you don't already have an SSH key for an account. If you do have an SSH key and you want to generate another key, you'll have to use the terminal because you can't use Sourcetree to create a second key. Creating an SSH key looks something like this: From the Sourcetree menu, select Preferences.
Add SSH key to a Jenkins Git step. Posted by Laszlo Pinter February 15, 2017 February 15, 2017 Leave a comment on Add SSH key to a Jenkins Git step. To access a Git repository Jenkins can use an SSH key. To add the SSH key to the Jenkins server use the following Chef script. DevOps Engineering part 1. For Windows: Install the necessary plugins for the repository (ex: GitHub install GitHub and GitHub Authentication plugins) in Jenkins. You can generate a key with Putty key generator, or by running the following command in git bash: $ ssh-keygen -t rsa -b 4096 -C youremail@example.com Private key must be OpenSSH. Add your SSH private key to the ssh-agent and store your passphrase in the keychain. If you created your key with a different name, or if you are adding an existing key that has a different name, replace idrsa in the command with the name of your private key file.
First thing that you need to do on your macOS machine is to create a directory that will store your SSH keys. Then you will generate a public and private key for your account, launch the Terminal and punch in some commands:
Create a .ssh Directory
/3ds-xl-parental-controls-master-key-generator.html. Change to the home directory
Create a SSH directory name .ssh and move into it
Make sure that the file permissions are set to read/write/execute only for the user
Create your private and public key, the blank quotes at the end of the command gives the private key no password, so allowing for passwordless logins!
Change into the .ssh directory and list the contents of that .ssh directory
Thats your SSH keys created, the private key is the id_rsa and the public one is the id_rsa.pub, don’t give out the private one always keep that one only on your local machine.
Sharing the Public Key
Create an authorized_keys in the .ssh directory of the remote computer that you want to connect to.
You can create automatic logins by adding the contents of your public key to the authorized_keys file on the remote device.
To see and copy your public key use the cat command and copy the contents:
On the remote computer if needed, change the permssions on the authorized_keys file to write to add the public key, on a new line paste in your public key, and change permissions back to read only after for security.
Allow write on authorised_keys
Paste the entire id_rsa.pub content with vi or nano into the authorized_keys file, if using nano use the -w flag to not use incorrect line breaks.
If the remote host does not have an “authorized_keys” file simply create one and after the public key is pasted in don’t forget to takeaway write permissions.

Going Both Ways
So now when you connect via SSH no password is prompted as the remote computer has your public key which is only decrypted by your private key held in your local .ssh/ directory. If you want the communications to be bilateral then repeat the process in the opposite order between the two.
Now the two computers can securely connect with no password prompting, making it ideal to script between the two for file copies or back ups.

Now instead of typing in
Make an alias in your bash shell you could alias it to
Reload the the shell

Then all you have to type in is the alias
