New campus network certificate

Connected to our wired or wifi network on campus before? If yes, you accepted our network certificate the first time you did this on each of your personal and non-managed devices.

The time has come for this certificate to be renewed. It will be replaced on Thu 23 May.

Once this change is made, you may have to accept the new certificate on your devices when next connecting them to eduroam – expect to see a pop-up window appear and ensure you take action.

Some devices may not prompt at all (certain Android devices, for example) and the certificate will apply in the background without you noticing. Managed University desktops will be unaffected.

You will receive a direct email to your @dundee.ac.uk account shortly, which contains more detail.

Changes to wireless network service

We’re upgrading the University’s wireless infrastructure. Find out why in the One Dundee blog post.

This work will take place in the evenings (18:00 – 23:00) of Tue 2 and Thu 4 Apr.

Within each work window, each wireless access point should only be offline for approximately 10-15 mins at a time.

If you are connected to an access point when it upgrades / reloads the new software, the wireless controller should try and move your device to another available access point so you continue to get wifi. Due to the quantity of access point reloads, we can’t guarantee this in all circumstances and you may need to accept a short service outage.

If you have any questions, contact the Service Desk quoting ref C1901-027.

Sir James Black Centre Network Migration

The Sir James Black Centre will be migrated to the new wired network on the Wed 20 – Thu 21 Feb and Tue 26 – Wed 27 Feb. Migrations will take place between 08:00 and 18:00 and affect the following areas on the days/times indicted below.

  • Wed 20 Feb, JBC Floor G
  • Thu 21 Feb, JBC Floor 1
  • Tue 26 Feb, JBC Floors 2 and M
  • Wed 27 Feb, JBC Floors 3, 4 and 5

Keep the following in mind
You may find your device becomes active prior to the completion time. If this does occur, your network service should still be considered ‘at risk’ up until 18:00 on the day.

Some devices (such as printers) may need further configuration once the network equipment has been replaced. Work to update such devices will carried out on the days following the migration.

Impact
There will be no access to the wired network and disruption to the wireless network. If having internet access on the day of the migration is essential to your work, we advise that you relocate away from the building.

The migration will affect all client devices such as PCs and laptops, office desk phones, printers, building management systems etc connected to the University network.

Actions – if you’re using a:
Unmanaged computer
You need to enable 802.1x authentication on your wired network connection. This is something you can do prior to or right after the migration. Instructions to help you do this for your OS (Windows, macOS, or Linux) can be reached on the IT website.
Managed computers (Staff Desktop)
Take no action for these devices post-migration. They should automatically connect to the new wired network but may need to be rebooted if they have been switched on throughout the change.
If you need a refresh on how to connect your device to eduroam, which is already available in Life Sciences, visit the connect to eduroam wifi website guide.

Reporting issues / getting help
Once the work is complete, contact the Service Desk by phone on extension 88000 or online via Help4U.

All Sir James Black Centre activities will run on the new, next-generation network when complete.

Upgrade to new SonicWall VPN

We have identified an issue with our new Sonicwall VPN that is impacting a number of users. A fix will be applied on Tue 12 Feb between 07:15-07:45 that will require a number of reloads of the VPN and result in disruption for all users of it. The VPN service should be considered at risk up until 09:00 on the day.

Post-upgrade update
We initially thought all users would need to delete and re-install the client to take advantage of the fix. Post-upgrade testing has shown this only applies to people on Windows 10 devices.

Wellcome Trust Network Migrations

The Wellcome Trust building will be migrated across to the new wired network on the Thu 7 – Tue 19 Feb. Each Migration will start at 08:00 and end at 18:00. The following areas are likely to be affected on the dates given below:

Some devices (such as printers) may need further configuration once the network equipment has been replaced. Work to update such devices will carried out on the days following the migrations.


Impact
There will be no access to the wired network and disruption to the wireless network. If having internet access on the day of your migration is essential to your work, we advise that you relocate away from the area being migrated.

Migrations will affect all client devices such as PCs and laptops, office desk phones, printers, building management systems etc connected to the University network.

Disruption To Service

At approximately 4pm this afternoon a misconfiguration occurred during a standard operational procedure which resulted in an interruption to connectivity between some of our servers. This  in turn, affected a number of our services. This was quickly rectified by our engineers and the majority of services were restored by 4:30pm.  Please accept our apologies for any inconvenience this caused.

Wireless Connections in Main Library

We are currently receiving reports that users are experiencing intermittent connections to Eduroam on the 1st floor of the Main Library. We have raised this with our third party supplier and are working closely with them to resolve this problem in a timely manner. Our PCs in these areas are unaffected so feel free to use them whilst we work on solving your connection issues.

Decommission of legacy VPN

The University’s legacy Cisco VPN (pictured below) will be taken out of action this month (Jan) because it has now been replaced by the new SonicWall VPN.

Anyone using the old VPN is advised to install the new one as soon as possible to avoid disruption in the near future. Use the instructions on the IT website to help you do so.

SLS staff information: This is not a replacement for the Life Sciences VPN as yet. Since migrating your wifi to eduroam, you no longer need to use the Life Sciences VPN to access JBC resources when roaming campus. You do, however, need to continue to use the Life Sciences VPN when offsite to access these resources.
