How do I connect to MySQL?

Before you can access your MySQL database, you must request an account by sending an email to help@cis.ksu.edu.

Once your account has been created, you may connect using the instructions below.

You can connect to the MySQL server from any host on the campus network. You will not be able to connect to it from off-campus unless you use the KSU VPN client, which you can download here. Campus wifi users: you will not be able to connect if you are on the "KSU Guest" wifi network. If you are on wifi, you must be using the "KSU Wireless" network.

Connecting from Linux

To connect from Linux, you must first logon to one of the lab machines (or you may connect from your own laptop). Once logged in, you can connect to the MySQL server by typing: 

mysql -p -h mysql.cis.ksu.edu

and then enter your MySQL password when prompted.

Using phpMyAdmin

To administer your database through a web interface, you can use phpMyAdmin from any Internet-connected computer.

How do I change my MySQL password?

There are a couple of ways to change your password:

  • Connect using the command above. Once connected, type the following at the prompt 
set password = password("yournewpassword");

Where yournewpassword is your new password.

How do I reset my MySQL password?

Send an email to support@cis.ksu.edu or stop by the sysadmin offices (Engineering Hall 2217 or 2218) during regular business hours.

General Connection Information

You may find the following information helpful: 

MySQL Host: mysql.cis.ksu.edu
MySQL Port: 3306

A copy of the MySQL 5.5 documentation can be found at the MySQL homepage.

If you have any other questions or problems, please send a [request] to the system administrators.

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 CIS 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 CIS faculty are frequently asking students to configure and manipulate software on their own as part of homework assignments. As such the CIS 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 CIS 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@cis.ksu.edu or talk to one of the staff members in the main CIS 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 cislinux.cis.ksu.edu or any CIS Linux lab machine. Windows users must ssh into cislinux using Putty or another ssh client.

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

  1. Log into cislinux.cis.ksu.edu (or any CIS 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:
    3. $ 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:
    4. $ /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.

For More Information

Please see the Java PathFinder site:

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.cis.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

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 cislinux.cis.ksu.edu
  2. Run the install script
    3. $ /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
    3. > U: > cd pc2
  3. Start the PC2 client
    4. 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
    3. $ cd $HOME/pc2
  3. Start the PC^2 client
    4. $ 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 Academic Program, 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 webstore. 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 from "Kansas State University, Manhattan - Computing and Info. Sciences" (usually from noreply@kivuto.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.

If your account is currently active, or was previously added but you never activated it, you will not receive an email. If you previously had an account that had been deactivated (accounts are deactivated automatically after one year from their creation), you will receive an email saying your account has been reactivated. If you don't remember your password in either of these cases, click on the "Forgot you password?" link on the site login page. Your username will always be <your_eid>@ksu.edu.

Once your account is confirmed, you can login to the webstore any time at the following URL:

http://e5.onthehub.com/d.ashx?s=n6y2p4hmp2

You are free to download any software available on this site. Software available for students from the VMware Academic Program includes desktop applications, such as Fusion (for Mac OS), Workstation (for Linux and Windows), and Player (for all platforms). You can also get a discount code for enrollment in the VMWare Certified Professional program. Software for faculty includes all of these plus vSphere and vCenter products, as well as ESXi and ESX.

Remember, this is for you own personal use as a CS student. You are not legally permitted to download software for your friends or families. Doing so will break the terms of the agreement. Distributing illegal copies of software is against state and federal laws and the policies of this university.

How do I install Visual Paradigm UML on my own computer?

Getting the software

We have local copies of the current version of this software on our file server for your convenience. You can download it using SCP from cislinux.cis.ksu.edu and in the path /pub/software/Visual Paradigm. Alternatively, you can get it from any department Windows computer by browsing to \\files.cis.ksu.edu\software\Visual Paradigm and put it on a flash drive or upload to cloud storage for your retrieval later. We have installers for all OS platforms, choose any you like. You will also need the key in the file activation_code.txt in this same directory.

Install Activation Code

Once you have installed Visual Paradigm using the appropriate process for your OS, you will need to apply the activation code to use the software. Start the application and do the following:

  1. When you see the following screen, select Subscription/Academic License.
  2. Expand Academic Partner Program License.
  3. Paste the activation code from activation_code.txt there.
  4. Enter your name and email address.
  5. Click Activate. You are promted for activation code.
  6. Check your email for the verification code.
  7. Copy the verification code and paste to Visual Paradigm.
  8. Click OK to confirm. Visual Paradigm should now be activated.

Is there any other way to get help?

The best way to get our attention is to send an email to help@cis.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.
