Connecting to ada

Instructions for connecting to ada and installing a VPN for offsite work

We will use an on-premises (on-prem) server called Ada, named after Ada Lovelace, who wrote the first algorithm for the precursor to modern computers, Babbage’s Analytical Engine.

Offsite - use the VPN client

The ada server is accessible only from the UNCW network.

You will need to use UNCW’s Virtual Private Network (VPN) client software to reach the server while offsite.

  1. Install the VPN client software. You can only install the VPN client while offsite.
  2. Open the Cisco AnyConnect VPN program and connect to the pre-configured UNCW VPN.
  3. I recommend that you disconnect from the VPN when you don’t need it because it can slow your connection.

Connecting to ada via SSH

We will use the Secure Shell (SSH) program to connect to ada. SSH is an extremely popular software tool for creating client-server connections. SSH will connect you to ada’s Linux CLI, which will function like a WSL or MacOS Terminal.

SSH is pre-installed on MacOS, Ubuntu, and WSL. Open a Terminal and enter the following:

ssh <your-uncw-id>@ada.cis.uncw.edu  
# for example, ssh laymanl@ada.cis.uncw.edu

Enter your UNCW login password when prompted. Choose “yes” when prompted to trust the connected machine.

You should see something like the following after successfully signing in:

You are now logged into the ada server. ada is running Ubuntu Linux, and understands all the standard Linux CLI commands.

There are many commands at your disposal, including python and git.

Type pwd to see your home directory location.

Rules for using ada

ada is a shared server. As such:

  • Do not read, write, or edit files outside your home directory.
  • Do not change the permissions on your home directory using chmod or any other command.
  • Follow the Seahawk Respect Compact at all times.
  • Do not intentionally do anything to harm the server, such as fill up the hard disk or overload the CPU.

Activity on the server is logged. Any intentional or negligent violation of these rules will result in a grade of 0 for the course and a violation of the Student Code of Conduct reported to the Dean of Students.

When in doubt if you are allowed to do something, ask the instructor first.

Once you are done, move onto the Working on ada lab.
