Login

After you get an account, make sure you are under the Rutgers network (or behind a Rutgers VPN).

Terminal

Password Login

You may simply use Rutgers NetID password to login the server. Open a terminal, connect with ssh.

$ ssh <netid>@amarel.rutgers.edu  # Replace <netid> with yours

SSH-key Login (Optional)

This is a very handy tool. You can opt in this password-less way.

Generate your key

The basic program here is ssh-keygen.

$ ssh-keygen

After answering several questions, you can generate your key pair in ~/.ssh/, the private key id_rsa and the public key id_rsa.pub. You should never give away your private key. Remember your passphrase unless you left it blank. The passphrase is used to decipher your private key.

Put public key on the server

After receiving your key pair, you need to put your public key on the server. You can use a tool called ssh-copy-id.

$ ssh-copy-id -i ~/.ssh/id_rsa <netid>@amarel.rutgers.edu

Or, you may simply use scp to put your public key into the file ~/.ssh/authorized_keys. Or simply put the content of id_rsa.pub into the file.

Add your private key to ssh-agent

SSH-Agent can hold your private key, so that you don't need to type your passphrase every time unless you reboot your machine. Type

$ ssh-add ~/.ssh/id_rsa

The agent will ask your passphrase if applicable.
