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:
===From Mac/Linux===
- Open the Terminal and execute the following command:
ssh username@servername.cs.olemiss.edu
- 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.
===From Windows===
- 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 https://putty.org
- 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”
cd ~
mkdir public_html
- Set permissions of public_html to allow the world read and execute privilege
chmod -R 755 public_html
- Set permissions of your home folder to allow the world execute privilege
chmod 701 ~
- If successful, your webpage is accessible at http://turing.cs.olemiss.edu/~yourusername
How to set the Java PATH variable:
==Windows 10 and Windows 8==
- In Search, search for and then select: System (Control Panel)
- Click the Advanced system settings link.
- Click Environment Variables. In the section System Variables, find the
PATH
environment variable and select it. Click Edit. If thePATH
environment variable does not exist, clickNew
. - In the Edit System Variable (or New System Variable) window, specify the value of the
PATH
environment variable. Click OK. Close all remaining windows by clicking OK. - Reopen Command prompt window, and run your java code.
==Mac OS X==
To run a different version of Java, either specify the full path, or use the java_home
tool:
% /usr/libexec/java_home -v 1.8.0_73 --exec javac -version
==Solaris and Linux==
- To find out if the path is properly set:
In a terminal windows, enter:% java -version
This will print the version of thejava
tool, if it can find it. If the version is old or you get the error java: Command not found, then the path is not properly set. - Determine which java executable is the first one found in your PATH
In a terminal window, enter:% which java
Set the PATH permanently
To set the path permanently, set the path in your startup file.
Note: Instructions for two most popular Shells on Linux and Solaris are listed. If you are using other shells, see the Path Setting Tutorial.
Bash Shell
Edit the startup file (~/.bashrc
)
- Modify PATH variable
PATH=/usr/local/jdk1.8.0/bin:$PATH
export PATH
- Save and close the file
- Load the startup file
% . /.profile
- Verify that the path is set by repeating the
java
command% java -version
