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.

Adding your SSH key to the ssh-agent. Before adding a new SSH key to the ssh-agent to manage your keys, you should have checked for existing SSH keys and generated a new SSH key. When adding your SSH key to the agent, use the default macOS ssh-add command, and not an application installed by macports, homebrew, or some other external source. Dec 18, 2019 If there are existing keys, you can either use those and skip the next step or backup up the old keys and generate new ones.

If you see an existing public and private key pair listed (for example idrsa.pub and idrsa) that you would like to use to connect to GitHub, you can add your SSH key to the ssh-agent. /mirnex-pro-evolution-soccer-2015-key-generator-crack.html.

The private key file is automatically downloaded by your browser. Sep 26, 2019 You generate an SSH key through macOS by using the Terminal application. Once you upload a valid public SSH key, the Triton Compute Service uses SmartLogin to copy the public key to any new SmartMachine you provision.

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.

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

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

Ssh Key Generation

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. https://heavenlyspeak.weebly.com/blog/easy-to-use-cad-software-for-mac.

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.

Overview

OSG Connect requires SSH-key-based logins. You need to follow a two-step process to set up the SSH key to your account.

  1. Generate a SSH key pair.

  2. Add your public key to the submit host by uploading it to your OSG Connect user profile (via the OSG Connect website).

After completing the process, you can log in from a local computer (your laptop or desktop) to the OSG Connect login node assignedusing either ssh or an ssh program like Putty -- see below for more details on logging in.

NOTE: Please do not edit the authorized keys file on the login node.

Step 1: Generate SSH Keys

We will discuss how to generate a SSH key pair for two cases:

  • 'Unix' systems (Linux, Mac) and certain, latest versions of Windows
  • Older Windows systems

Please note: The key pair consist of a private key and a public key. You will upload the public key to OSG Connect, but you also need to keep a copy of the private key to log in!
You should keep the private key on machines that you have direct access to, i.e. your local computer (your laptop or desktop).

Unix-based operating system (Linux/Mac) or latest Windows 10 versions

Mac generate new ssh key pair authentication

Open a terminal on your local computer and run the following commands:

The last command will produce a prompt similar to

Unless you want to change the location of the key, continue by pressing enter.Now you will be asked for a passphrase. Enter a passphrase that you will be able to remember and which is secure:

When everything has successfully completed, the output should resemble thefollowing:

The part you want to upload is the content of the .pub file (~/.ssh/id_rsa.pub)

Windows, using Putty to log in

If you can connect using the ssh command within the Command Prompt (Windows 10 build version 1803 and later), please follow the Mac/Linux directions above. If not, continue with the directions below.

  1. Open the PuTTYgen program. You can download PuttyGen here: PuttyGen Download Page, scroll down until you see the puttygen.exe file.

  2. For Type of key to generate, select RSA or SSH-2 RSA.

  3. Click the 'Generate' button.

  4. Move your mouse in the area below the progress bar.When the progress bar is full, PuTTYgen generates your key pair.

  5. Type a passphrase in the 'Key passphrase' field. Type the same passphrase in the 'Confirm passphrase' field. You can use a key without a passphrase, but this is not recommended.

  6. Click the 'Save private key' button to save the private key. You must save the private key. You will need it to connect to your machine.

  7. Right-click in the text field labeled 'Public key for pasting into OpenSSH authorized_keys file' and choose Select All.

  8. Right-click again in the same text field and choose Copy.

Step 2: Add the public SSH key to login node

To add your public key to the OSG Connect log in node:

  1. Go to www.osgconnect.net and sign in with the institutional identity you used when requesting an OSG Connect account.

  2. Click 'Profile' in the top right corner.

  3. Click the 'Edit Profile' button located after the user information in the left hand box.

  4. Copy/paste the public key which is found in the .pub file into the 'SSH Public Key' text box. The expected key is a single line, with three fields looking something like ssh-rsa ASSFFSAF. user@host. If you used the first set of key-generating instructions it is the content of ~/.ssh/id_rsa.pub and for the second (using PuTTYgen), it is the content from step 7 above.

  5. Click 'Update Profile'

The key is now added to your profile in the OSG Connect website. This will automaticallybe added to the login nodes within a couple hours.

Mac Get Ssh Key

After following the steps above to upload your key and it's been a few hours, you should be able to log in to OSG Connect.

Determine which login node to use

Before you can connect, you will need to know which login node your account is assigned to. You can find this information on your profile from the OSG Connect website.

  1. Go to www.osgconnect.net and sign in with your CILogin.

  2. Click 'Profile' in the top right corner.

  3. The assigned login nodes are listed in the left side box. Make note of the address of your assigned login node as you will use this to connect to OSG Connect.

For Mac, Linux, or newer versions of Windows

Open a terminal and type in:

Generate Ssh Key Osx

It will ask for the passphrase for your ssh key (if you set one) and then you should be logged in.

For older versions of Windows

On older versions of Windows, you can use the Putty program to log in.

  1. Open the PutTTY program. If necessary, you can download PuTTY from the website here PuTTY download page.

  2. Type the address of your assigned login node as the hostname (see 'Determine which login node to use' above).

  3. In the left hand menu, click the '+' next to 'SSH' to expand the menu.

  4. Click 'Auth' in the 'SSH' menu.

  5. Click 'Browse' and specify the private key file you saved in step 5 above.

  6. Click 'Open' and provide your passphrase when prompted to do so.
