Below you will find how-to guides and tips for using the Adler Labs and student servers, as well as installation and troubleshooting tips for commonly used software in the Department.
How to SSH to Turing and other student servers:
- Open the Terminal and execute the following command:
- Where ‘username’ is the name of your account and ‘servername’ is the name of the server you are trying to access (in most cases this will be turing.cs.olemiss.edu).
- Accept the key if prompted to do so.
- You should be prompted for a password. Once the password is entered and accepted, you will have remote access to the server.
- The newest versions of Windows 10 have ssh installed by default. You can use ssh from the command line just as described above for Mac and Linux computers.
- If your version of Windows is not up to date, you can use Putty to open an ssh connection:
- If using the Alder Labs or any other Windows machine in the Csci Department, putty should be installed and can be accessed from the desktop or start menu.
- If putty isn’t installed you can get it for free from http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html
- Run putty and enter the name of the server you want to SSH to (ex: turing.cs.olemiss.edu) in the hostname field.
- All the other settings are correct by default.
- Press enter and click yes if prompted.
- Enter your username and password to gain access.
How to create your own webpage on Turing:
- Create a folder in the root of your home folder called “public_html”
- Set permissions of public_html to allow the world read and execute privilege
chmod o+rx public_html
chmod 705 public_html
- Set permissions of your home folder to allow the world execute privilege
chmod o+x ~
chmod 701 ~
- If successful, your webpage is accessible at http://turing.cs.olemiss.edu/~yourusername
