It is possible to connect to the School of IT Linux terminal servers via SSH, SSH with X11 forwarding and RDP. Below are the instructions for each one of these method.
Connection Steps:
1. Connect
with the Cisco VPN only if you are
off campus
2. Click
on the name of the server on the following page
a) Linux
Terminals Connection Page
b) Or
you can manually Remote Desktop or SSH into the one of the servers as listed in
the table
below
3. At the login screen, enter your ISU credentials and log in.
Please note: you do not require an active campus network connection to
connect to login.it.ilstu.edu but you
do need at least a VPN connection to the campus network to connect to any of the
terminal servers directly via RDP or SSH.

Remote Desktop:
You can use any remote desktop client to connect into either
the name or IP of the table listed above.
PLEASE NOTE: The remote desktop connection must be set to
24bit color depth or less
in order to work.
i.
On Windows run remote or Remote Desktop Connection
ii.
On Mac, download Microsoft
Remote Desktopas a free download through the app store
iii.
On Linux, it will depend on the version, but overall
we recommend rdesktop
SSH:
SSH is built into the OSX and Linux terminals.
i.
On Windows the PuTTY
client can be downloaded and used: www.putty.org
a. Enter the IP of the terminal
server you wish to connect to, use port 22
When you are done, you can save the connection information by going to "Session" entering a name for the connection (e.g., ash) and clicking "Save" Next time you want to connect to the same server, select the connection you saved and click "Load".
ii.
In OSX, open the terminal and type "ssh -l *ULID* *IP*" where
*ULID* and *IP* are your ULID and the IP of the terminal server you wish to
connect to or type "ssh ULID@terminalservername.ad.ilstu.edu" for instance.
a. Example: Users-MacBookPro:~ User$ ssh -l myulid 10.21.100.45
This allows you to open GUI applications via a terminal window. This will most likely provide increase performance working with graphical interface applications compared to RDP and is recommended on slower connections.
Directions for Windows users.
i. In addition so step i. from the previous section, you will need to download and configure an X11 server on your local machine and enable X11 forwarding in your SSH connection:
1. After downloading and installing the X11 server, launch it. For simplicity, leave all the options to their defaults and click "next" until you are prompted to "Save configuration" or "Finish". If you save the configuation to your desktop, for instance, you'll be able to quickly launch your Xserver quickly in the future.
2. Once ready, you should see a a new icon in your notification area/system tray:
3. In PuTTY, expand Connection, SSH, X11 and check "Enable X11 forwarding".
When you are done, you can save the connection information by going to "Session" entering a name for the connection (e.g., Oak) and clicking "Save" Next time you want to connect to the same server, select the connection you saved and click "Load".
4. Click "Open" and log in to the terminal server you are connected to. Once you're logged in, you can launch programs such as Eclipse, Firefox and so on through the terminal and a new window should pop up of the program you launched. The program should behave exactly as it would in a RDP session.
Directions for Mac users.
1. Download XQuartz and install.
2. Open a terminal window and run "sudo nano /private/etc/ssh/sshd_config"
3. Enable the X11Forwading option by removing the hashtag as in the example below:
4. Exit nano by pressing CTRL-x. When prompted to save, press "y" to confrm and then press Enter to exit.
5. Restart the computer to apply the changes.
6. Establish the SSH connection by:
a. Open a terminal window
b. run "ssh -Y ULID@terminalservername.ad.ilstu.edu" where terminalserver name could be Oak, Walnut, Pine or Maple.
7. Once connected, you should be ready to launch any GUI application from the command line, such as "firefox", "eclipse" and so on.
Additional Info:
All terminal servers have the same software and settings
