Add your public key to the submit host by uploading it to your OSG Connect user profile (via the OSG Connect website). Before adding a new SSH key to your GitHub Enterprise account, you should have: Checked for existing SSH keys; Generated a new SSH key and added it to the ssh-agent; After adding a new SSH key to your GitHub Enterprise account, you can reconfigure any local repositories to use SSH.

  • Open Terminal

  • Check if you already have a SSH keypair generated. Do the following:

    If the files exist, you already have SSH installed. IMPORTANT: But if you wish to regenerate the SSH key pair, at least back up your old SSH keys.

  • Generate a 4096-bit key pair - yes, use the higher bit

  • Enter a file in which you want to save your keys. You can press enter and the default ~/.ssh/id_rsa will be used.

  • Enter a passphrase. Read Github working with SSH key passphrase articule on why you should use a passphrase and at the same time you don't have to enter the passphase everytime you use your SSH key.

  • From here on your SSH key pair is generated, your SSH public key is ~/.ssh/id_rsa.pub - the one with the pub extension. BE EXTRA CAREFUL when using your ~/.ssh/id_rsa file. This is your private key, guard it properly.

Windows

  1. Install Git for Windows
  2. Open Git Bash and repeat the above instructions

Overview

OSG Connect requires SSH-key-based logins. You need to followa 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 toyour 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 formore 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 thepublic 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 havedirect access to, i.e. your local computer (your laptop or desktop).

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

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 beable 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 PuttyGenhere: PuttyGen Download Page,scroll down until you see the puttygen.exe file.

  2. Folder lock 7 registration key. 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. Youcan 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 likessh-rsa ASSFFSAF.. user@host. If you used the first set of key-generatinginstructions it is the content of ~/.ssh/id_rsa.pub and for the second (usingPuTTYgen), 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.

Logging In

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

To generate a DH key pair, with the OpenSSL command-line tool, you have to do it in two steps: openssl dhparam -out dhparam.pem 1024 openssl genpkey -paramfile dhparam.pem -out dhkey.pem For an ECDH key pair, use this: openssl ecparam -out ecparam.pem -name prime256v1 openssl genpkey -paramfile ecparam.pem -out ecdhkey.pem. View below to go straight to the DHKE portion of the lecture. OpenSSL provides both a library of security operations you can access from your own software, as well as a command line mode. In the past I've given examples of using OpenSSL to generate RSA keys as well as encrypt and sign with RSA. View dh key generated from openssl test session 3. Apr 12, 2017  By default, it contains the following command.openssl.exe dhparam -out dh.pem -2 1024 2 dh.log To create DH parameters with a 2048-bit key, replace 1024 with 2048 in generatedh.bat. When executed, this results in the file dh.pem with this key length. Please note that the longer the generated key is, the longer will it need to be generated.

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 findthis 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 ofyour 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:

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

For older versions of Windows

Generate A Ssh Key For Git

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.
