SSH (secure shell), SCP (secure copy), and SFTP (SSH file transfer protocol) access to

  • bobby.cs.unlv.edu (131.216.23.6)
  • cardiac.cs.unlv.edu (131.216.23.8)
  • java.cs.unlv.edu (131.216.23.15)

via Internet is presently available.

We may change policies and procedures for remote access to handle the load as need arises.

Using Linux machines in TBE B-361

The entire TBE B-361 lab runs Linux, although the front row also dual boots Windows. If you are using a computer in the front row and want to use Linux follow these directions.

When you log into Linux in the lab, you will have access to the exact same files as you do when connected to bobby.cs.unlv.edu. To access a terminal prompt on the Linux machines after you are logged in go to Applications -> System Tools -> Terminal.

Even though you have access to your files directly, it is highly recommended that you follow the steps below to connect to bobby because there may be differences in installed software. Notably, you cannot use the submit script without connecting to bobby and the compiler may have differences. Once your terminal window is open, follow the steps below to log in to bobby:

  1. At the prompt type ssh username@server (e.g. ssh smithj1@bobby.cs.unlv.edu) and hit Enter
  2. An authentication warning may appear that looks like this:
The authenticity of hosts 'bobby.cs.unlv.edu (131.216.23.6)' can't be established. RSA key fingerprint is 
xodif-lolyn-bohuh-foleg-cokec-boged-hihaf-helam-mosim-feros-pyxix 
Are you sure you want to continue connecting (yes/no)?
  1. Type yes and hit Enter
  2. Enter your password and hit Enter

Using Windows machines in TBE B-361

Only the front row of machines in TBE B-361 run Windows. These machines dual boot, so if you want to use Windows and they are currently booted to Linux (CentOS), follow these directions.

To access your files stored on bobby, you will need to use a SSH client as below:

  1. Open the SSH client by going to Start -> Program -> Secure Shell Client
  2. Once the program is open hit spacebar or Enter
  3. A window will appear asking for hostname and username
    • For hostname enter one of the servers above (e.g. bobby.cs.unlv.edu)
    • For username enter your login name
  4. An authentication warning may appear that looks like this:
The authenticity of hosts 'bobby.cs.unlv.edu (131.216.23.6)' can't be established. RSA key fingerprint is 
xodif-lolyn-bohuh-foleg-cokec-boged-hihaf-helam-mosim-feros-pyxix 
Are you sure you want to continue connecting (yes/no)?
  1. Select yes

Note: This is the same program that is installed on computers in TEC classrooms.

Remote access

You may connect to any of the servers above from your home or any location with an Internet connection. See the sections below for details on connecting to a shell (terminal access) or transferring files via SCP/SFTP. SSH fingerprint can be checked for security.

Terminal access

  • Secure Shell Client - remote terminal access program for Windows
  • Bitvise - remote terminal access program for Windows
  • PuTTY - remote terminal access program for Windows
  • macOS - remote terminal access using macOS
  • Secure Shell - remote terminal access program for Chromebooks / Chrome OS / Chrome web browser
