Internet outage: Feedback

Friday, October 4th, 2019

Early on Thursday morning we were notified by our internet provider, TENET, that there has been a break in internet connection between UWC and SUN. This caused an internet outage on the entire SU network for most of the morning.

Technicians were immediately dispatched to the site and after investigating, established that the infrastructure has been vandalised and the fibre cable cut. Maintenance then proceeded to replace the damaged equipment and restore connectivity. Unfortunately both primary and secondary links were compromised and also had to repair the backup link.

We apologise for the inconvenience and appreciate your patience. During incidents such as these please remember to follow our Twitter feed where we will post regular updates.

 

Change your password online

Thursday, February 28th, 2019

In the past, the IT Service Desk was your first stop when you forgot your password (we know, it happens to us too!) or had to change your password. Unfortunately, due to various security risks, as well as the very strict new data protection acts, the Service Desk is no longer allowed to change or reset your password for you. (You can read more about the university’s own Data Privacy Regulation here)

We would like to encourage staff and students to use the Password Selfhelp website in future. We realise that this might be inconvenient, but for your and our own protection, we will have to follow this procedure. 

 The Password Selfhelp website (www.sun.ac.za/password) offers two options: 

  1. Change Password for users who know what their password is and want to change it. 
  2. Reset Password for users who forgot their password. 

To use the online Password Selfhelp, your cellphone number or an alternative email address has to be on the HR records, otherwise, you will not be able to change your password. You can update this information by logging onto SUN-e-HR though the staff portal,  http://my.sun.ac.za or contacting your department’s HR contact person. 

Select the My Profile link – Personal Information

Log on to SUN-e-HR.

Select Basic Details – Update, Other, Personal Email Address 

or

Select  Phone Numbers – Update

During the password change process a PIN code, consisting of 8 numbers, will be SMSed or emailed to the user (depending on which option he/she selected) Please use this PIN to change your password on the self help website. As soon as the password has been changed, the user will be notified by means of SMS or email.

If you have not requested a password change, please notify the IT Service Desk immediately at 808 4367.

High internet costs? Here’s why.

Monday, April 9th, 2018

Occasionally we receive enquiries regarding seemingly high Inetkey costs, especially from students. Usually, the causes are fairly straight-forward and can be easily prevented. 

It’s very difficult to say what is causing or what the source of the traffic is without actually looking at your Inetkey logs. So, to start, before contacting us about your Inetkey usage, first look at your logs on http://www.sun.ac.za/useradm and go to the [View Internet Usage] tool and under “View Type” select “Source” and select USER to refresh the display. If you take note of all the IP addresses and see if they are in fact your devices, you will get a better idea of which device is generating the traffic and at which times.

Keep in mind that Stellenbosch University has numerous times been rated as having the fastest internet in South Africa. Current speed tests show that the download speed is 95.29 MB per second and an upload speed of 58.12 MB per second. Subsequently, you can easily run up a massive Inetkey bill within minutes.

The following are a few potential causes for high Inetkey usage:

  • Windows 10 updates that cannot easily be switched off with traditional means. However, if the device is on the SU network and set up to receive updates from IT’s WSUS server, updates will be downloaded locally and not run via Inetkey.
  • Updates stopping and restarting or not completing. Windows 10 1709 Creative Update is a little under 4Gb.
  • Inetkey being left open on a device that is unattended overnight or during classes.
  • Video streaming from sites not on the firewall exception list. Watching an HD streamed movie during the day and evening can generate 3Gb of data per hour.
  • Using a laptop as a wifi hotspot for a cell phone to save on data costs.
  • Using filesharing protocols like BitTorrent. Remember that uploads and downloads both generate traffic. If you use BitTorrent you are also seeding and will also pay for someone downloading your own files.
  • Syncing files to DropBox.
  • Weak passwords allowing neighbours and friends to share internet connections from adjacent rooms.
  • Passwords being leaked to a friend or partners and then abused at a later stage.
  • Viruses or malware included in BHO that spam and generate traffic. Often compromised e-mail accounts will cause high internet usage, because InetKey and email use the same password.
  • Inetkey accounts being used on multiple devices.

If none of these seems to be causing your high Inetkey usage, you can ask Information Technology to investigate your internet usage (or issues). If you have a query send a complaint within 14 days to helpinfo@sun.ac.za. The cost of an enquiry is R200.00 per enquiry. If an error is found, the administrative fee will not be levied.

Forgot to reactivate?

Tuesday, April 3rd, 2018

To have access to internet, email and any other network service, you need to reactivate your username annually. If you haven’t reactivated for 2018, your access will have expired on 4 April. What do you do now?

  1. You will not be able to access the network from your devices. In order to reactivate, use a colleague’s PC or laptop.
  2. Browse to the following address: www.sun.ac.za/useradm.
  3. You will see three options:
    Sign on 
    Forgot password
    Reactivate expired username

    Select Reactivate expired username.

4. You will be asked to sign in with your username and ID number or Passport number. See example below.

5. After signing in, you will see a list of options for your username, as well as the appropriate cost points options. 

6. Select the usernames you want to activate and fill in the correct cost point. This is very important. Rather make sure which cost point you should use from your department’s financial officer. If it’s incorrect it will result in a delay of your activation. 

7. Your request for activation will be forwarded to your cost centre manager. 

8. As soon as they approve it, you will have access to the SU network again.

 

 

OneDrive for Business: Anonymous file sharing

Monday, January 22nd, 2018

Information Technology recently assessed our OneDrive for Business platform to ensure that no security risks exist for our users and network. During this assessment we identified a number of users who are currently using the anonymous sharing function (“Anyone with the link can view and edit”) on OneDrive.

With anonymous file sharing there is no control or record of who has access to the shared files. Anybody who has the link can access and/or edit the files. This poses a security risk for the University and our users. For this reason we are compelled to switch off anonymous usage.

From Thursday, 1 February 2018 you will no longer be able to share files anonymously on OneDrive. Sharing will still be possible with internal and external users, but at a higher security level.

Guides on best practices for sharing files on OneDrive is available www.sun.ac.za/itselfhelp under the Office365 section or directly on this page. If you are have any enquiries, please contact the IT Service Desk by emailing help@sun.ac.za or calling our Service Desk at 808 4367.
