Mac/Linux/Windows(PowerShell)
Before generating new SSH key pair first check if you have an SSH key on your local machine.
ls ~/.ssh/id_*.pub
If there are existing keys, please move to Step 3
Mac/Linux
Windows (PowerShell)
ssh-keygen -t rsa
ssh-keygen.exe
Press Enter to accept the default file location and file name.
The
ssh-keygen
will ask you to type a secure passphrase. This is optional. If you don't want to use a passphrase just press Enter
Verify the SSH keys are generated correctly, you should see two files
id_rsa
and id_rsa.pub
under ~/.ssh
directory.DO NOT upload or send the private key.
You will now need to copy your public key to Oscar. There are two ways to acomplish this.
If your OS comes with the
ssh-copy-id
utility, then you'll be able to copy your public key into Oscar as follows:ssh-copy-id <username>@ssh.ccv.brown.edu
You will be prompted for a Password. The public key will be appended to the
authorized_keys
file on Oscar. If you used a custom name for your key instead of the default
id_rsa
then you'll need pass the name of your key to ssh-copy-id
i.e.,ssh-copy-id -i ~/.ssh/<keyname> <username>@ssh.ccv.brown.edu
If your system does not come with the
ssh-copy-id
utility installed, then you'll need to copy your public key by hand.- 1.Get the contents of
id_rsa.pub
file. One option is to usecat
in your teminalcat id_rsa.pub
. - 2.Copy the contents of this file to your clipboard, as we need to upload it to Oscar.
- 3.Login into Oscar via regular ssh
ssh <username>@ssh.ccv.brown.edu
. Once you are on the login node, open the authorized_keys file with your text editor of choice e.g.,vim ~/.ssh/authorized_keys
ornano ~/.ssh/authorized_keys
Add your public keys to end of this file. Save and exit.
ssh <username>@sshcampus.ccv.brown.edu
If everything went well, you will be logged in immediately withouth prompting you for a password.
