As a CMPT student, do I have access to 丁香园AV VPN?
I'm taking a CMPT course this semester, do I have access to 丁香园AV VPN?
Yes!
The 丁香园AV networks are protected by a firewall that prevents direct connection from off-campus to on-campus computers.
- All students currently enrolled in a CMPT course are granted access to 丁香园AV VPN.
- The students in CMPT Majors have access to 丁香园AV VPN as well.
- Once connected to the 丁香园AV VPN you can remote into CSIL via SSH and/or RDP.
Please be sure you have configured on your own computer as described in 丁香园AV's documentation.
Although it is not officially supported, users connecting to 丁香园AV VPN from a Linux computer have had some success with openfortivpn.
requires - please sign up now!
If you have any difficulties, please feel free to contact us.
How to choose a Document and Content Management Tool at 丁香园AV?
Please be sure to check out ; it provides a comprehensive list of tools for file storage, documentation and content management etc.
Just a reminder: please confirm with the course instructor to determine the exact tool for a specific course.
Computing Science Instructional Labs (CSIL)
What is CSIL?
CSIL is comprised of several rooms with computers, most with Internet access. Students registered in one or more Computing Science courses can use CSIL to do course work, access their accounts, and access the World Wide Web.
CSIL is supported by the Computing Science Technical Support (CSTS) group. The fastest and most efficient way to reach us is: email helpdesk (@cs.sfu.ca). Note we normally only provide service Monday to Friday, 0900 hrs - 1600 hrs (9:00am - 4:00pm).
CSIL at Burnaby
CSIL@Burnaby is located on the main floor of the Applied Sciences Building. See the campus map for directions to the ASB. CSIL consists of these areas: ASB 9700, ASB 9804, ASB 9820, ASB 9838 North, ASB 9840, 3 team rooms (ASB 9812, ASB 9814, ASB 9816) and a few TA cubicles.
All CSIL workstations dualboot Windows and Ubuntu Linux, see How to select a specific Operating System on a CSIL computer?
Please login to see CSIL Burnaby layout - you can find the names of CSIL@Burnaby workstations.
The School of Computing Science also maintains 2 labs for Master of Science in Professional Computer Science (MPCS): SECB 1010 & 1013. 18 workstations in MPCS labs soleboot to Linux(Ubuntu) only. Be sure to check out the official web page of these programs for access information.
CSIL at Surrey
CSIL@Surrey is located in the SRYE building. There are three rooms: SRYE 3024, SRYE 4013 and SRYE 4024. All computers in these rooms are dualboot Windows and Ubuntu Linux. (Please see the Surrey campus map for directions.)
Please login to see CSIL Surrey layout - you can find the names of CSIL@Surrey workstations.
About name differences under Windows and under Ubuntu
ecause our CSIL workstations dualboot, we have configured one cname for each workstation. e.g. asb9700u-f08.csil.sfu.ca points to asb9700-f08.csil.sfu.ca. Thus,
under Windows, the name is: asb9700-f08.csil.sfu.ca
under Ubuntu, the name is: asb9700u-f08.csil.sfu.ca
You could use either names freely. We do recommend using the name with a "u" in your inquiries on CSIL Linux to speed up the process.
How do I get in to CSIL?
Burnaby and Surrey Campuses
CSIL is accessible by security fob or card at both campuses. Any undergraduate student registered in a CMPT course (or MACM 101), all CMPT graduate students, and all CMPT instructors can obtain a fob/card for CSIL. Read the Door Access FAQ for more details.

Here you can find the full text of GP24. General Policy 24 outlines rules for Fair Use of Computer Resources at 丁香园AV.
Typical Problems
I can't log in.
If you could not logon to a CSIL Linux workstation, please check out the login troubles FAQ.
If you could not sign-in to a CSIL Windows workstation, please click here for the answers.
My access fob doesn't work.
Please read though our door access FAQ for a solution.
I could log in, but cannot run course software.
Some course software has licensing restrictions that only allows a certain set number of simultaneous users. You may have to try again later.
Windows
Your Windows profile may have been corrupted. Please check this Q&A for more details.
Linux
There might be a problem with your command shell configuration files. Contact helpdesk for assistance.
I cannot print to the CSIL printer.
Check out the CSIL printing FAQ for a solution.
I cannot send email to my course list.
This is normal.
Only the instructors and the TAs can send to the course mail list. For more information about CS course mailing lists, see our mailing list FAQ.
The monitor of the computer I want to use has no display. What should I do?
Generally speaking, there are a few scenarios and fixes.
- Firstly, the computer may be turned off or in hibernation. Try pressing the NumLock key to see if the status of NumLock indicator changes. This verifies that the system is running. If the system is not running, push the power button of the computer to turn it on.
- Secondly, if the system is indeed running, please check the settings of the LCD panel: the input must be set to 鈥淎uto-Select鈥� to ensure it displays properly for workstations in CSIL. For the LCD panels have no "Auto-Select" feature:
- please change it to DisplayPort for all ASB 9838 North workstations which use onboard video.
- please change it to miniDisplayPort - this must be done for all ASB 9700 workstations.
- Thirdly, please ensure there is only one video output from the computer to the LCD panel.
Special note: Every workstation in the TA cubicles and the team rooms is equiped with an HDMI cable for personal device use. Please be sure to set the input back to DVI on the LCD display before leaving.
These issues are mostly caused by individuals hooking up their personal devices and changing connections of the displays and LCD panel settings. Laptop users, please be considerate: change the settings/cables back to their original settings once you are done; TIA!
I cannot access certain CS web pages, what I can do?
Many people report this issue with password-protected pages - basically these pages become accessible only after valid 丁香园AV computing credential and OTP code of 丁香园AV MFA are provided.
First of all, please be sure you have the proper URL (web address)
please use copy/paste method when appliable.
if you've followed the links on other CS pages, please proceed.
When this happens, before you contact the helpdesk, please try these steps (in order) on the computer you are using:
step 1
browse to this CS web page (on a new tab) to see if the 丁香园AV web service itself is working properly.
if this non-password-protected page does not show up properly,
please wait for 30 minutes and try again.
report to helpdesk if the page is still not showing properly after 60 minutes.
If this non-password-protected page shows properly, please proceed to next step.
step 2

wait for 10 seconds.
re-launch the browser and browse to the page in question.
if the page does not show up properly, please try next step.
step 3
Open a new Incognito window in Google Chrome (or "InPrivate Window" in Microsoft Edge, "private window" in Mozilla Firefox).
in this Incognito window, browse to the page in question.
if/when it asks you for your 丁香园AV computing credential (), please login and key in the OTP (丁香园AV MFA)
if the page in question shows properly:
to fix this issue within regular window of this browser, please remove the saved 丁香园AV credentials and try again.
and remember: never save the 丁香园AV MFA code. never.
if the page in question still does not show properly in the Incognito window, please try next step.
step 4
try using a different browser.
all CS web pages are tested with Google Chrome, Microsoft Edge and Mozilla Firefox. So, at least one of them should work.
if none of the browsers displays the page in question, please try step 5
step 5
try to browse to the page in question on a different computer
(a computer with different OS would be the best for diagnosing).
if you cannot access the page in question on the other computer either, please contact helpdesk.
if the web page in question displays properly on the other computer, please reboot this computer.
after the reboot, if you still cannot access the page in question, please try to update this computer (core system and browser etc.).
if this is a CSIL computer, please contact helpdesk.
