This page provides instructions on how to connect to USC servers using OpenSSH, a password-based authentication method that provides a secure connection with a remote system.
When you set up SSH, you create a key pair that contains a private key (saved to your local computer) and a public key (uploaded to Bitbucket). Bitbucket uses the key pair to authenticate anything the associated account can access. This two-way mechanism prevents man-in-the-middle attacks. This first key pair is your default SSH identity.

It is included in every Linux and Unix system. For free trial downloads of SSH.COM Tectia SSH Client/Server:. Tectia SSH Client free trial. Tectia SSH.
- Connect to your service via SSH. Open your Terminal application. You will see a window with a $ symbol and a blinking cursor. This is your basic command prompt. From here, you may issue the command to establish the SSH connection to your server. The most basic usage of this is as follows. Be sure to replace 00000 with your site number.

What You Will Need
- G3 Processor and above, running Mac OS X
- An Internet connection
- A USC faculty or staff computer account. For additional information about USC accounts, please refer to the Accounts and Passwords page.
Connecting to USC Using OpenSSH
- Open the Applications folder within the Utilities folder.

- A window will display the following information:
- At the command prompt ($), type the following:
- A window requesting your password will appear. Enter your password to log in and access your account.
You can connect to USC and gain remote access to applications by using X11 x-windowing software. For information on how to use X11, please refer to the X11 for Mac OS X page.

Introduction
As of April 12, 2019, SSH keys are required when SSHing to CS/CSRES networks when outside of our networks, campus wireless, or the VPN. The University ISO will quarantine any host allowing SSH access that has not disabled password authentication. Zoo tycoon for mac.
An SSH key pair consists of two keys: One public key and one private key. The public key, as the name suggests, is public and can be safely shared with the world. The private key should never be shared with anyone and should be kept safe.
In order to use SSH keys to connect to a remote computer, one must first create an SSH key pair on one's computer, then copy the public SSH key to the remote computer. You will create an SSH key pair on each computer that you want to SSH from. You can use the same public SSH key from one computer to connect to many others.
E.g., if you have two computers at home, home1 and home2, and want to use them to connect to remote1, remote2, and remote3 you would create an SSH key pair on both home1 and home2, and then send the public key from home1 to all three remote computers, and lastly you would send the public key from home2 to all three remote computers.
Below are the necessary instructions to create an SSH key pair and add your public key to your CS account. Adding your public SSH key to linux.cs.utexas.edu will automatically add it to all other machines on the CS network. For the purposes of these instructions, we will assume that you want to SSH into a CS machine from a computer at home. To avoid confusion, we will use the following terminology:
HOME = Your home computer
CS_USER = Your CS username
linux.cs.utexas.edu = The machine that you need to SSH into and add an SSH key to.
NOTE: All commands will be run on HOME.
Creating a key
To create a 4096-bit RSA key, run the following:
Ssh Program For Mac
ssh-keygen -t rsa -b 4096
- Press Enter to use the default location. (Recommended) 1
- Enter a passphrase (ALWAYS use a passphrase!!) 23
- Enter your passphrase a second time.
It should look something like this:
Your public SSH key is located by default at
~/.ssh/id_rsa.pub
and is perfectly safe to be shared with anyone.Your private SSH key will be located by default at
~/.ssh/id_rsa
. You should NOT touch this file or share it with anyone.Copying your key to a server
From UT VPN, UT wireless, or CS network
If you are connected to UT VPN, or have brought your machine on campus and have connected to UT wireless or the CS network, then you can use one of the methods below. If for any reason the ssh-copy-id method does not work, you can still copy your public SSH key manually using the second method.
You can find more information on how to connect to UT VPN by visiting this page.
Using ssh-copy-id
To copy your SSH public key from HOME to linux.cs.utexas.edu, simply replace the
ssh
in a normal SSH command with ssh-copy-id
, as shown below: Mt4 for mac os x.ssh-copy-id [email protected]
- If you see the text 'Are you sure you want to continue connecting (yes/no)?' type
yes
and press Enter. - Enter CS_USER's password to send your public key to the server.
It should look something like this: Rylo mac app requirements.
Congratulations! You can now use your SSH key to log into any CS machine that you have access to!
Using the manual method
If for any reason the ssh-copy-id method does not work, you can still copy your public SSH key manually.
cat ~/.ssh/id_rsa.pub | ssh [email protected] 'umask 0077 && mkdir -p ~/.ssh && cat >> ~/.ssh/authorized_keys'
- If you see the text 'Are you sure you want to continue connecting (yes/no)?' type
yes
and press Enter. - Enter CS_USER's password to send your public key to the server.

Copy to a USB drive
If you are unable to connect to UT VPN or cannot bring your machine to campus, then copying your public SSH key to a USB drive is another solution.
On your home computer: Signal for mac.
- Plug in a USB drive.
- If it does not auto-mount, open a file manager and open the USB device to view its contents.
- In a terminal, run
df -hT
to find the full path to your mounted USB drive. (Your USB's mountpoint path will likely start with/media/yourusername
) cp ~/.ssh/id_rsa.pub /media/yourusername/directory/
(Replace the second path with your real USB drive's mount point path)- Safely unmount/eject your USB drive and bring it to campus.
From here, you will want to log into a CS lab machine and do:
- Plug in the USB drive
- If it does not auto-mount, open a file manager and open the USB device to view its contents.
- In a terminal, run
df -hT
to find the full path to your mounted USB drive. cat /media/yourusername/directory/id_rsa.pub >> ~/.ssh/authorized_keys
(Replace the second path with your real USB drive's mount point path)chmod 700 ~/.ssh && chmod 600 ~/.ssh/authorized_keys
- If step #5's command gives any errors, please submit a helpreq.
- Safely unmount/eject your USB drive.
Using ssh-agent (optional)
ssh-agent is a program included in OpenSSH that will remember your SSH key and not require you to type its passphrase each time you use SSH. Your desktop environment on HOME should start up ssh-agent when you log in.
- Type in your SSH key's passphrase and you're good to go!
Office for mac student. You won't need to type in your passphrase any longer. Once you log out ssh-agent will be killed and you will need to repeat the above process the next time you log in.
Additional information
- If you choose to not use the recommended location for your private key, you will need to specify its location in either your
ssh
command (with -i) or after yourssh-add
command if using ssh-agent.↩ - This is not your CS_USER's password. The passphrase that you choose for your SSH key should be different from your CS_USER's password. See Selecting a strong password to learn how to choose a secure passphrase instead of a password.↩
- When typing your passphrase, you won't see any output on your screen. This is normal and is for your security.↩
