Accessing the Aries UNIX/Linux Server


Purpose: To help students access the CIS Aries UNIX/Linux server using an SSH client.

The Aries UNIX/Linux server is used by students in several CIS classes at LSC. The primary method that students use to access this server is with a Secure Shell (SSH) client. SSH is a communication protocol that allows for secure remote access to a command line (shell) over an unencrypted channel, such as the Internet. 

A great SSH client, called PuTTY, can be downloaded for free from PuTTY's homepage. Instructions for using PuTTY to access the CIS Aries server are as follows.

  1. Download the most recent version of PuTTY from the project's homepage. Install the program, and run it.

  2. When the program runs, the PuTTY Configuration window opens. Type the address of the Aries server in the Host Name (or IP address) box: Make sure that the Port box contains the number 22, and that the Connection type is set to SSH. Click the Open button to initiate the connection.

  3. If this is the first time you have connect to the Aries server with PuTTY, you may be prompted to confirm the server's host key. Click the Yes button and continue. Once the connection has opened, you will be prompted for your username.
  4. Enter your username and press Enter. You will immediately be prompted for your password. Enter this as well.

  5. Once you have entered your correct username and password, you will be greeted with a command prompt. From here, you can access hundreds of command line utilities.

Note: If you accidentally enter the wrong username and/or password several times in a row, your account will be temporarily locked out. This is a security mechanism designed to protect the Aries server from unauthorized access. If this happens to you, wait a few minutes and try it again. If you are still unable to access your account after 10 minutes, contact the CIS Student Workers at
