tuxworld.usask.ca is the department's Linux cluster available to all Computer Science faculty, staff, and students. Tuxworld is accessible from both on- and off-campus and has the majority of the software packages found on the Linux lab computers.
Command-line remote access to Computer Science machines is provided via the ssh protocol. tuxworld.usask.ca can be used as a gateway for ssh access to computers on campus that may not be directly accessible. The easiest way to connect via ssh is through the command prompt. If you are running Windows 10, macOS, or Linux on your local computer, you can simply use 'ssh NSID@tuxworld.usask.ca' to connect to tuxworld.usask.ca.
Windows 7 and older versions of Windows 10 do not have ssh built in. If you are not running a version of Windows 10 with ssh, you should be. Please upgrade. If you are unable to upgrade, PuTTY is a free implementation of ssh and is available here: PuTTY Download Page
TUXWORD VIA REMOTE DESKTOP PROTOCOL
To access tuxworld via the Remote Desktop Protocol (RDP) you need to use a RDP client. Most versions of Windows come with a RDP client called "Remote Desktop Client". macOS users can download the Microsoft Remote Desktop App for free; information is available from the ICT website here. Linux users can install an RDP client of their choice (e.g. "rdesktop", "Remmina", "FreeRDP", or "kdrc"). There is a good chance that at least one of these are in your Linux distribution's package repositories.
Direct RDP access to tuxworld.usask.ca is only allowed from certain on-campus machines. If you are using a personal Windows or macOS computer you must configure your RDP client to use the campus RDP Gateway. Instructions for doing so can be found here. If you are using a personal Linux computer with an RDP client that is unable to connect to an RDP gateway, you will need to first connect to the campus VPN. Instructions for connecting to the VPN are found here. After connecting to the VPN you will be able to use direct RDP to tuxworld with the Linux RDP client.
CHANGE YOUR DESKTOP ENVIRONMENT
To change your desktop environment from the default Gnome3 environment to a different one, you will have to do the following:
- Create a file called .Xclients in your linux home directory (ie. /student/<NSID>).
- Add one of the following without the quotes to it.
- "gnome-session" for the Gnome3 desktop environment.
- "startkde" for the KDE/Plasma desktop environment.
- "mate-session" for the Mate desktop environment.
- "cinnamon" for the Cinnamon desktop environment.
- "startxfce4" for the Xfce desktop environment.
- Make sure it is executable (chmod 700 .Xclients).
- Try to login using the RDP client.
This section outlines the staff and their duties, as well as various services and what staff look after them. For nearly all enquiries and requests creating a Trac ticket is the preferred first step.

August, 2014: The U of S has adopted a new management system for student copying, scanning, and printing. This new system offers several benefits to students but also adds an extra configuration step when setting up department printers on student machines. The new system requires that students run a client application on their computer whenever they want to access department printers. ICT will be providing the client software and detailed installation information in the near future. Until the ICT site is updated please use the following instructions for installing and using the PaperCut Client software:
Download the PaperCut Client application for your platform from the department website:
- Unzip the downloaded file into the location of your choice (downloads, desktop, etc.).
- There is no installation per say. The PaperCut client application can be launched directly from the unzipped folder.
- Windows: launch pc-client-local-cache.exe. You can also create a shortcut to this application for easier access.
- Mac OS X: launch PCClient.app. You can also move the app to the Applications folder for easier access.
- Linux: launch pc-client-linux.sh.
- When the client starts you will be asked to authenticate with your U of S nsid and password.
- When you print a document the client must be running. A login window will pop up asking you to authenticate. Enter your nsid and password. You can tell the client application to remember your credentials for a period of time (default 5 minutes).
- Mac Users Note: The current client (version 14.2.x) has a bug that may prevent you from typing in the login window. If you encounter this, click OK on the login window and then OK on the resulting error window. You will then be taken back to the login window and will be able to type in your nsid and password.
- You may exit the PaperCut client whenever you are done printing and/or not on campus.
- Note: the client application talks to the UofS PaperCut servers and therefore you only want to run the client when you are printing on campus.
Printers are named according to the lab or room in which they reside. In general, you should only print to the printer located in the lab you are in.

Instructions on configuring a printer in Windows 10 are as follows:
- Remove all existing department installed printers that point to atog.usask.ca
- Add csprintspool to the Windows 10 Credential Manager by doing the following:
- Open the Credential Manager from the Start Menu
- Click on "Windows Credentials" and then "Add a Windows Credential"
- Fill in the details as follows:
- Server address: csprintspool
- Username: usask\<NSID> (where <NSID> is your NSID. If your NSID is abc123, then Username is: usask\abc123)
- Password: <Enter your NSID Password>
- To add a new printer:
- Open "Printers and Scanners" from Settings
- Click on "Add a printer or scanner" - this will scan for available printers on the network
- Once scanning is done look for the printer that you wish to add
- If the printer is there, click on it, then click "Add Device".
- If the printer is not there:
- Click on "The printer that I want isn't listed" below the list of available printers.
- Choose "Select a shared printer name"
- Enter the printer name in the form: \\csprintspool\<PRINTERNAME> (e.g.: \\csprintspool\thorv377)
- Click on "Next" to install the printer driver
- Set the printer as default, if desired
- Click on "Finish"
Users of Linux, on non-lab machines, can use the following instructions to access the printers. These instructions will give you access to all printers, and any changes that are made on the server side will automatically show up.
- Log on to the machine with an administrative user, that has the ability to use sudo.
- Open a terminal application.
- Execute the following commands:
- cd /etc/cups
- sudo vi client.conf
- Search for the line starting with ServerName
- Add the following line underneath:
- ServerName sobek.usask.ca
- Excecute the following commands:
- sudo killall cupsd
- sudo cupsd
- Open the Printer Setup Utility and choose the appropriate printer as your default.
OS X - MAVERICKS AND NEWER
Users of OS X 10.9, on non-lab machines, can use the following instructions to access the printers. These instructions will give you access to a specific printer; individual printers must be added as required.
- Use Printers & Scanners interface in System Preferences
- Click the plus sign to add a printer
- Click the Advanced tab and wait for it to populate
- NOTE: If the Advanced tab is not visible:
- Control-click on the tool bar of the 'Add' window.
- Choose 'Customize Toolbar...'

- NOTE: If the Advanced tab is not visible:
- Select the Type: Windows Printer via spoolss
- Enter the URL for the printer: 'smb://csprintspool/printername' where printername is the (lower-case) name of the printer you wish to print to (e.g. thorv60bw1).
- THORV-176-RIC URL for the printer is 'smb://printq.usask.ca/THORV-176-RIC (Additional details on the Ricoh and Macs are found here).
- In the 'Name' field type what you wish the printer to be called in OS X once the printer driver is installed (e.g. ThorvG60bw1) (Spaces in this name may cause issues -- it is likely best to avoid them)
- In the Use field click Select Software...
- Choose the make and model of the printer and click 'OK'. Click 'Add' to add the printer.
- You must download and install the Ricoh driver from the Ricoh site (https://www.ricoh.ca/en/support-and-download). Type the model number into the search (MP C4504)
- Set any additional settings for the printer and click 'Set Default Options'.
- The printer should now be installed.
Note: If you require Lexmark printer drivers they can be found on the Apple Support website here. Your print job should go through and you should no longer have to enter your password to print.Note that the first time you attempt to print you may be asked for your network password. Ensure that you enter 'usask;abc123' (yes, use your NSID, and yes, the ';' must be used instead of the usual '\'. '\' will not work.) for your username. Check the save in keychain box otherwise it will prompt you every time and may even prompt you twice every time.
- The printer may be down. Please inform Op Centre staff in Spinks S330 in the Thorvaldson Building Spinks Addition, or send submit a Trac Ticket.
- You are likely out of printing pages. You must purchase printing pages before you are able to print. Check your print account to make sure that you do have printing pages.
- Cabinet - Storage on cabinet.usask.ca is provided by ICT. This is the location of your home directory when you are using Windows in Computer Science. This is also your default Windows home directory on non-Computer Science equipment. cabinet.usask.ca:/work$/abc123 (where abc123 is your NSID) is the path to the folder on a Windows machine, and cabinet.usask.ca:/work$/abc123/cmpt/cswin is the full path to where your home directory is saved when using Windows on a Computer Science machine.
- Computer Science fileservers - Your storage on csfiles.usask.ca is in /student/abc123 . If you are a returning student, you may still have data in /student/machome/abc123 as well.
For simple access to your Windows files you can connect to PAWS and follow the instructions here. For additional access to your Windows files see the instructions here. Once you are connected to the campus VPN, you can access your Computer Science Linux files on a mapped network drive by pointing to csfiles.usask.ca/<NSID>.

The Department of Computer Science provides and mantains a variety of drives for students, staff and faculty. Undergraduate and graduate students have a quota of 50GB. Backups are performed regularly, and restores can be performed in emergencies.
|H: Drive||This is an ICT administered network drive where you can save your files and information on. This is the location\\cabinet\work$\abc123.|
|M: Drive||This is the historic Computer Science administered Mac OS X home directory.|
|V: or T: Drive||This is an ICT administered network drive that is mounted from cabinet.usask.ca. Backups are performed regularly, and restores can be performed upon request. For more information, please see The ICT Webpages.|
Undergraduate Computer Science lab accounts will expire at the end of every four months; i.e., at the end of December, April, and August. The expiry of the accounts generally corresponds with the end of final exams. Graduate accounts are valid as long as a student is registered in graduate studies. They expire when the account falls into disuse for roughly one year.
Students who enroll in courses offered by the Department of Computer Science (any CMPT or BINFO course, and MATH 211, 313, or 314) have an account created for them automatically. Students must have a Network Services ID (NSID) and password in order to log in.
Undergraduate accounts expire at the end of every four months; i.e., at the end of December, April, and August. The expiry of the accounts generally corresponds with the end of final exams. Graduate accounts are valid as long as a student is registered in graduate studies. They expire when the account falls into disuse for roughly one year.
When you login to a lab machine running Linux or a remote access server you are automatically given a Kerberos ticket. This ticket is good for 10 hours. If the ticket expires, you will get a "Permission Denied" error when attempting to access your files. The easy 'fix' is to just run 'kinit', enter your NSID password, and you will get a new ticket. If you intend to run a longer running process (e.g. on tuxworld) you will need to make arrangments to have your Kerberos tickets renewed automatically.
If you intend to have a long-running process (over 10 hours) on tuxworld, for example, you will need to arrange for your Kerberos ticket to be renewed before the 10-hour expiry time elapses.
A simple way to do that is to run the following Python script:documents/krb5autorenew.py
Sometimes computers in the lab might be unaccessible and display a locked screen. Please do not press the power switch! These are multi-tasking, multi-user UNIX-like machines. Other people may be logged in and using the machine even if you are unable to log in at the console. Please find a lab attendant (if available) and let them know of the problem, and then use an alternate machine.
All Linux machines will normally boot up into an X11 display, with a graphical login prompt. To switch to one of the text-based consoles, use CTRL-ALT plus F2-F6 (corresponding to the console you want). To switch to X11 again, use CTRL-ALT-F1.
The following lists are the required software for current acamdemic year. Unless specified, software available on a particular platform will be available both on the lab machines and the terminal servers. These lists are not exhaustive, but specifiy the software required for classes.
The Department of Computer Science is licensed under the Microsoft Azure Dev Tools for Teaching program (Formerly known as Microsoft DreamSpark program, and once also known MSDN Academic Alliance). This enables all current department faculty, staff, and students to access software available under the program. This allows the department to provide legal copies of certain Microsoft software for academic and non-commercial use.
For more details and to access software, see Microsoft Azure Dev Tools for Teaching. Login with NSID@usask.ca and your usual NSID password for access.
Undergraduate students registered in a Computer Science class in the current term are eligible to access the Microsoft Azure Dev Tools for Teaching software library. Computer Science faculty, graduate students, and staff will continue to have access to the Azure Dev Tools for Teaching library while part of the department unless notified.
Faculty, staff, and students use their NSID and associated password to log onto the Microsoft Azure Dev Tools for Teaching website. Please note that although the Microsoft website is hosted on non U of S servers that authentication (where nsid and passwords are entered) is done on a U of S server.
EMAIL FROM THE MICROSOFT AZURE DEV TOOLS FOR TEACHING SYSTEM
As per U of S policy all email from Microsoft website servers will be sent to your NSID account hosted on mail.usask.ca (email@example.com). If you prefer a reading your email from a different account you will have to set up your @mail.usask.ca account to be forwarded to that account.
AVAILABLE SOFTWARE PRODUCTS
The Microsoft Azure Dev Tools for Teaching subscription allows the Department to supply several Microsoft products to students for academic use. Examples are:
- All Microsoft Operating Systems
- Visual Studio (non express versions)
- Visio Professional
- Project Professional
All provided software packages are available one or more of the following delivery options:
- Downloading of CD or DVD ISO images. These images are intended to be used to make a CD or DVD using the appropriate disc burning software.
- Direct delivery from Microsoft. Discs may be purchase for a small fee directly from Microsoft. The fees are typically less then US$20.00 plus shipping.
NOTE: REGARDING DOWNLOADS...
The downloads are compressed and encrypted. A small Windows or OS X based application is used to download and unwrap the ISO image file. This means that the downloading must be done from a Windows or Mac OS X computer.
If downloading at home on a Windows machine and you do not have software that can create a CD from an ISO image file check out ISO Recorder .
You can only access the Microsoft Azure Dev Tools for Teaching site and software while you are part of the Department of Computer Science; as in currently taking a class offered by the department or on payroll in the department.
This means that as an undergraduate student you will not have access to the Microsoft Azure Dev Tools for Teaching site in between terms (ex: during summer) or during a term that you are not taking a class offered by the Department of Computer Science.
