The different Linux-based computers on the Georgia Tech Ground Station Network are linked via secure shell protocol (SSH). Before accessing the computers over SSH, an intermediate connection to the GT Aerospace Tunnel must be established.
Windows
In order to establish a connection to the AE Tunnel, it is recommended that the program PuTTY be downloaded beforehand. This program allows for SSH connectivity. Using PuTTY, enter in the address ssh.ae.gatech.edu and click enter.
Linux
Accessing the SSH tunnel using Linux requires no additional programs. Open the Linux terminal and enter the command:
ssh 128.61.186.233
AE Tunnel
The AE tunnel will prompt for a username. Only students/faculty associated with the GT Aerospace Department have access to the SSH tunnel. If the ground station user wishes to access the tunnel but doesn’t have access, email an aerospace professor and ask for SSH gateway access.
Once the AE tunnel is accessed, three of the four ground stations are now accessible by their own addresses:
M. Knight: ae-glrg-405135.ae.gatech.edu
Van Leer: ae-glrg-405136.ae.gatech.edu
CCRF: ae-glrg-499162.ae.gatech.edu
To access these addresses, the ground station user must be granted access to them by the Aerospace IT department with the approval of an Aerospace professor. Once the approval is granted, enter the following command to gain access:
ssh ae-glrg-XXXXXX.ae.gatech.edu
With this, the user will be able to view the directories of the other ground station computers.
GTRI VPN (Baker Only)
The Baker Ground Station cannot be accessed through the AE tunnel, as it is operated by GTRI and not the GT Aerospace Department. Instead, it can only be accessible through the GTRI VPN. Using the GT-distributed Cisco AnyConnect Secure Mobility Client, connect to the address vpn1.gtri.gatech.edu. Under “Group,” select Duo-GTRI-EOSL. Enter credentials, and type “push” under “Second Password” to receive a Duo push. If successful, connection via the GTRI VPN has been established.
Windows
Using PuTTY, enter in and connect to the IP address 10.80.12.234. A terminal should open immediately thereafter asking login as:. User name and password credentials will be given to all authorized ground station users upon request.
Linux
Open the command terminal and connect to the IP address 10.80.12.234 via the command:
ssh <user_name>@10.80.12.234
The terminal should prompt immediately thereafter asking login as:. User name and password credentials will be given to all authorized ground station users upon request.
