How do I get and use Zoom for my classes?

The official platform for KSU to host remote instruction is Zoom. The main page for downloading the client and finding documentation is [1]. You do not need to login to join a class, but your instructor may prefer it. If you do want/need to login there is a handy set of instructions here.

Unless your instructor says otherwise, you do not need to have or use a webcam to join a class. If you do, any USB camera or one built into your laptop or monitor will work.

If you will need to interact with your class using audio, we strongly recommend a headset with a built-in boom microphone. we find these work better than desktop stick type microphones, or those built into your webcam or laptop. These can be purchased inexpensively from your favorite technology store.

Information for Instructors

Need some help using Zoom effectively for your classes? There are many resources available with helpful advice:

• There are articles linked from the Zoom portal page
• Handy one-page Getting Started flyer from KSU IT support
• Several articles in the KSU IT support knowledgebase
• Many tutorial videos and how-to articles on the Zoom support site

How do I use CLion on my own computer?

The department has an academic license for JetBrains products, including CLion. As long as you are a student, you may run the software and connect it to our license server. Here's how you do that.

1. You will need to download the CLion application from the JetBrains website. As of now, the link to that is here: https://www.jetbrains.com/clion/download. Install the application as usual on your computer.
2. In order to connect to our license server, you must use the university VPN client on your computer. Instructions on downloading, installing, and using that can be found here: https://www.ksu.edu/vpn
3. Once you have done both of the above steps, connect to the VPN and launch CLion. You should be prompted for license activation. The dialog should look something like this:
4. Fill out options on the dialog as shown above. Click on the Test Connection button and you should see a Connection successful message below the button. If you see this, then everything is connecting correctly.
5. Click on the Activate button. You should now see the message Floating ticket obtained Click on Continue to close the dialog and finish launching the application.

The next time you use CLion, as long as you are connected to the VPN, you should get your license again. If you are not connected to the VPN, when the application tries to connect to the license server, it will fail and and ask you to reactivate. If you do not reactivate, you will get kicked out of the application.

If you ever want or need to change your license settings, click on the Help menu and select Register.

What happens when I leave? How long do I keep my account?

Please see the "Account Removal and Alumni Accounts" section of the Accounts page.

Can you guys help me with my homework?

We want to make our policy on helping students clear. The CS support staff is responsible for making sure the computing systems, networks, services, and programs on those systems function. We will help anyone who has a problem using these systems.

However, we draw the line at looking at any source code or server or program configurations students themselves have installed. This is due to the fact that CS faculty are frequently asking students to configure and manipulate software on their own as part of homework assignments. As such the CS support staff explicitly do not examine source code or other issues for students.

If you are convinced that this problem is indeed an issue related to a CS systems bug or misconfiguration, you may contact your professor and ask for assistance. At the specific request of faculty members we will look into source code or other issues, but only in order to determine the location of the problem.

As an additional clarification, this policy doesn't preclude us from answering questions and giving advice to students. The systems coordinator and students may volunteer to render help or give advice at their discretion. Please be sure your requests for advice are keeping with your professors' honor code requirements for the applicable course.

What do I do when the printer is out of paper?

If one of the printers runs out of paper, you just need to contact the system administrators. We get paper and load the printers on request.

Alternately, if no one is available at those locations you may either email support@cs.ksu.edu or talk to one of the staff members in the main CS office, Nichols 234.

How do I use VMWare in the Computing Labs

Please read our guide for full details on using a VM image for classwork.

How do I install JPF (Java PathFinder)?

Initial Steps

The JPF install script may be run from cslinux.cs.ksu.edu or any CS Linux lab machine. Windows users must ssh into cslinux using Putty or another ssh client.

Once you have completed the installation from any Linux machine, it will work on any other CS Linux machine.

1. Log into cslinux.cs.ksu.edu (or any CS Linux lab machine). All following command should be run in a terminal session or terminal window.
2. Make sure the Sun JDK is in your system path. You should see something like this:
$ set | grep JAVA_HOME JAVA_HOME=/usr/lib/jvm/default-java $ set | grep PATH PATH=/usr/bin:/usr/local/bin:/usr/bin:/bin:/usr/games:/usr/lib/jvm/default-java JAVA_HOME could also be something like /usr/lib/jvm/java-6-sun. If JAVA_HOME is not set and not also in PATH, you will need to add the following to your ~/.profile: export JAVA_HOME=/usr/lib/jvm/default-java export PATH=$PATH:$JAVA_HOME Logout and back in to load the new configuration, or just reload it for your current session $ source ~/.profile
3. Now you can run the install script which will place the JPF files in your home directory and build them:
$ /common/public/bin/install_jpf.sh

You will now have a built copy of JPF in ~/JPF2.

Running JPF

Create the following shell scripts to help you build and run JPF test classes:

compile.sh

JPF=$HOME/JPF2/
CLASSPATH=.:$JPF/jpf-core/build/jpf/
CLASSPATH=$CLASSPATH:$JPF/jpf-core/lib/*
CLASSPATH=$CLASSPATH:$JPF/jpf-core/src/main/
javac -cp $CLASSPATH $1

run.sh

JPF=$HOME/JPF2/
CLASSPATH=.:$JPF/jpf-core/build/*
CLASSPATH=$CLASSPATH:$JPF/jpf-core/lib/*
CLASSPATH=$CLASSPATH:$JPF/jpf-core/build/classes/
CLASSPATH=$CLASSPATH:$JPF/jpf-core/bin/
CLASSPATH=$CLASSPATH:$JPF/jpf-core/src/main/
ARGS="+vm.por.sync_detection=false"
ARGS=$ARGS" +jpf.report.console.property_violation=trace,error,snapshot"
ARGS=$ARGS" +jpf.listener=.tools.DeadlockAnalyzer"
ARGS=$ARGS" +deadlock.format=essential"
java -Xmx512m -jar $JPF/jpf-core/build/RunJPF.jar +classpath=$CLASSPATH  $ARGS $1

Place them somewhere in your homedir (in your JPF2 directory is probably a good place) and make them executable

$ chmod +x compile.sh
$ chmod +x run.sh

See your instructor for how to use these scripts.

How do I use PC^2 for the ACM Programming Contest?

PC^2^ is used for submitting solutions and scoring for the ACM Programming Contest. You may either use a local fat client (pc2team) or the web client (EWTeam).

Web Client: EWTeam

Point a web browser to http://pc2.cs.ksu.edu and login with the credentials provided by the contest coordinator. This should work for all browsers and all operating systems. You can also look at the current scoreboard from this app.

Local Client: pc2team

To use the local client, you must install it in at least one team member's home directory.

Previously Installed Copy

IMPORTANT NOTE: If you used PC^2 for previous contests, you must remove the old directory before installing the current one. Look for a "pc2" directory on your U: drive or in your home directory and delete it before continuing.

Installation

1. Login to a Linux lab machine, or open an SSH session using PuTTY or another SSH client to cslinux.cs.ksu.edu
2. Run the install script
$ /common/public/bin/install_pc2.sh

Running

In Windows

1. Open a Command Prompt window (click Start->Programs->Accessories->Command Prompt, or Start->Run and type cmd)
2. Change to your home files (U: drive) and enter the pc2 directory
> U: > cd pc2
3. Start the PC2 client
U:\pc2>bin\pc2team

You cannot run pc2team by double-clicking on it in Windows Explorer, you must start it from the command prompt as described here.

In Linux

1. Open a terminal window
2. Enter the pc2 directory in your home directory
$ cd $HOME/pc2
3. Start the PC^2 client
$ bin/pc2team

All Platforms

• Login using the credentials provided to you by the judges.

• Note 1: you must run the pc2team application as described here, do not cd bin first and then run pc2team, otherwise the client will not be able to read its configuration file and you will not be able to connect to the server.

• Note 2: if you wish to view the current scoreboard, you may run the application pc2board instead of pc2team in the last step listed above.

Usage

Full documentation of the pc2team client can be found in the pc2 install directory in your home directory. Look in the doc directory for the file PC2V9TeamGuide.pdf.

I need some software by VMWare for a project, can you give it to me?

Possibly. Our licensing with VMWare, via the VMware IT Academy, allows us to give students software and licenses to install software on their own computers, for a period of 12 months at a time. Software may be obtained from the VMWare IT Academy Website (https://itacademy.brightspace.com/). At the beginning of each semester, we update the online database with a list of all students currently enrolled in a CS class. When we do this, you will receive an email with the subject "Welcome! Please redeem your VMWare subscription!" (usually from info@itacademy.brightspace.com) which contains a link that you will need to click to activate your account and set a password for it. Webmail will sometimes flag this as spam, so if you don't see it in your Inbox, please check in your Spam/Junk folders to see if it is filtered there.

Registering your VMWare IT Academy Account

Registering your account can be confusing. You can find full documentation here. If you have any further problems or questions, please contact CS IT support.

Downloading Software from VMWare IT Academy

Downloading software and obtaining keys can be confusing. You can find full documentation here. If you have any further problems or questions, please contact CS IT support.

Can I get MATLAB?

There is no campus site-license for MATLAB. The information available from university IT can be found here: https://www.k-state.edu/it/software/software-licenses/matlab/index.html

If you wish to use it, there are a few options for you.

I want to run MATLAB on a computer owned by the department

You may install your own copy and use one of the very small number of floating licenses available on campus. Floating licenses are shared with all computers configured to use them. They are available on a first-come-first-served basis. If you would like to do this, please contact us and we can assist you.

Alternatively, your major professor can purchase a license for you from Mathworks. Perpetual licenses are $500 each, annual licenses (must be renewed every year) are $250 each. Most additional toolboxes are $200 for perpetual or $100 for annual. Each toolbox must be purchased separately. Your major professor will need to fill out a purchase request on the Selfserv site to do this.

I want to run MATLAB on my personal computer that I own

You may purchase your own student license from Mathworks. The cost is $49 for MATLAB or $99 for the suite, which includes MATLAB, Simulink, and 10 popular toolboxes. You may also ask your major professor to pay for this license for you. Your major professor will need to fill out a purchase request on the Selfserv site to do this.

I want to run MATLAB on Beocat

Beocat has licensed the MATLAB compiler and several toolkits. You write your own code and then use Beocat to compile it to an executable. For details, see their documentation: https://support.beocat.ksu.edu/BeocatDocs/index.php/Installed_software#MatLab_compiler

Is there an open source option?

The other alternative is to use octave, which is largely compatible with Matlab, but is open source and free to use, and we have it installed on our cslinux servers. Your students can also install and use it on their Linux desktops. You can find more information about that here: https://www.gnu.org/software/octave/

Is there any other way to get help?

The best way to get our attention is to send an email to help@cs.ksu.edu. This creates a ticket in RT (Request Tracker), which we use for monitoring and tracking all helpdesk issues. This in turn sends all the sysadmin staff an email so we can all have a chance to respond to your question. Please do not send emails to any individual sysadmin. If you do this, there will be no record of your question, and it may take longer to be addressed.

If you have a question during regular business hours (Monday-Friday, 8AM-5PM), you can stop by the sysadmin offices: Engineering Hall 2217 and 2218. If your issue is quick and easy, we can usually take care of it right there for you. If it's a little more involved, we might still ask you to send us an email to open a ticket for it.

Also during business hours, you can reach us by phone at 785-532-6350 and asking for the system administrator. If there is an after-hours emergency, you can call 785-532-7790 and it will be forwarded to the system administrator.

If you're the kindof person that likes IRC, we have a channel on Freenode that you are free to join and ask your question. You can plug the following details into the IRC client of your choice:

Network: irc.freenode.net
Channel: #ksucis

There is usually one or more sysadmin lurking on this channel that can help you. We don't monitor this 24/7, but it's another easy way to reach us if you need to. If we are working on an issue that requires extended debugging and interaction, we may ask you to join so we can get some realtime feedback with you. For more detail on using IRC, see our Advanced IRC Tips page.
