SSH

How to access your repo with ssh.

SSH Key Setup & Pushing First Project

MacOS or Linux:

Check for SSH keys

ls -al ~/.ssh

If there are any ssh keys, this will show them.

If you don’t have a ~/.ssh directory, go ahead and make one

mkdir ~/.ssh

To setup a ssh key:

ssh-keygen -t rsa

which will prompt you to select a location for the keys.

The default is the ~/.ssh directory.

If this is your first ssh key, and you choose the default, hit and enter.

Press enter at “Enter file in which to save the key (/home/username/.ssh/id_rsa)”

Choose Y to overwrite.

At “Enter passphrase (empty for no passphrase): Enter same passphrase again:”

The resulting files are the private key which is id_rsa, and the public key which is id_rsa.pub.

To get the public key : (for Linux)

cat ~/.ssh/id_rsa.pub

(for MacOS)

pbcopy < ~/.ssh/id_rsa.pub

copy the public key output and paste in your code.vt.edu settings/ssh keys “key” box.

Secondary SSH Key

if you already have a key and want to create another, use the following, replacing with your name or what you want:

ssh-keygen -f ~/.ssh/<username>

“Enter passphrase (empty for no passphrase): Enter same passphrase again:”

to view that public key: (for linux)

cat ~/.ssh/<username>.pub

(for mac os)

pbcopy < ~/.ssh/<username>.pub

Windows

download and install putty: http://www.putty.org/

to generate key: https://www.ssh.com/ssh/putty/windows/puttygen
