This guide will show you how to enable SSH (remote login) on your Mac OS X machine and connect to it using a private key file (.ppk) while disabling password logins (more secure). In this example, we will setup the remote connection using Putty.
Generating ssh keys from asp.net core. Ask Question Asked 2 years, 8 months ago. Viewed 744 times 1 $begingroup$ I have started to create a console app, which I am testing locally on my mac.

Setting up public key authentication Generate an SSH Key Copy the key to a server Test the new key Troubleshooting How ssh-copy-id works Some best practices for SSH keys Use a passphrase when possible Add a command restriction when possible Managing SSH keys Command-line options Ssh-copy-id on Mac Installation using Homebrew Installation from. Apr 10, 2012 Multiple SSH Keys settings for different github account create different public key. Create different ssh key according the article Mac Set-Up Git $ ssh-keygen -t rsa -C '[email protected]' Please refer to github ssh issues for common problems. For example, 2 keys created at: /.ssh/idrsaactivehacker /.ssh/idrsajexchan. PuTTYgen is a key generator tool for creating pairs of public and private SSH keys. It is one of the components of the open-source networking client PuTTY. Although originally written for Microsoft Windows operating system, it is now officially available for multiple operating systems including macOS.
Create a .ssh directory. This directory will be hidden in your Mac X User home path.
Generate SSH private and public keys.
![]()
Create the authorized_keys file in Terminal.
authorized_keys - your shared public key file
id_rsa - your private key
id_rsa.pub - your public key
Note:You can run PuttyGen.exe on Mac OS X following this guide. Otherwise, you will need to run PuttyGen on a Windows machine.
You now have a .ppk file we can use for our Putty connection. Save this key somewhere safe and never share it with anyone!
Next, we will configure SSH on our Mac to only allow key authentications and disable password authentications. This will immediately drop a connection made to our Mac unless a key file is being used (more secure).
Configure SSH on Mac OS X to Force Private Key Authentication Only
Change UsePAM no
Uncomment and change PasswordAuthentication no
Now, we can use Putty to create an SSH connection to our Mac we generated our keys on. Download and install Putty here.
Note:You can run Putty.exe on Mac OS X following this guide.
Open Putty and create a new connection. We will point to our private key file (.ppk). Go to Connection -> SSH -> Auth and load the .ppk file here. This can be tricky, ensure your creating a new connection in Putty and saving it so it remembers the key we just imported.
Try connecting. You will receive a login prompt for username. This will be the user of your Mac (any other username you put here will fail immediately).
If successful, you will login to your shell immediately pictured below! No password needed!
