Technical information on mobile work in connection with the Corona virus

Representation of a virus
Due to the continuing spread of the corona virus, mobile work is becoming increasingly important. University members can also access our IT services from outside. We have put together a few notes in order for our systems to handle significantly larger numbers of users.

In order to contain the further spread of the Corona virus the intensive use of Home Office is advised. To make this as comfortable as possible for you, pragmatic solutions are needed. At the same time, confidentiality, availability and integrity need to be upheld.

Due to the sudden development of this situation not all of this could be set up in advance. Therefore we have put together a few notes, to advise you how to organize your Home Office as well as possible.

If you have any questions or problems, please contact the IT Servicedesk electronically: servicedeskattu-freiberg [dot] de

Arranging your workplace

IT Security

While working from home security measures that are comparable to the ones in your office need to be made:

  • When leaving your work station always lock your computer and if needed also your door.
  • Prevent others from gaining access (e.g. via open windows).
  • Only use ways of communication that can be verified by your colleagues.
  • Be aware of potential phishing mails exploiting the current situation in order to access sensitive data regarding personal passwords, etc.

 


Business notebook

If you are using your business notebook, supplied by the university, you already have access to all required information.

If this is not the case you can find all necessary information on the URZ website and can access your e-mails via your browser (using Webowa or Horde).


External monitor

It is possible to connect an external monitor to your notebook in order to use a larger display or several different displays.

Communication via phone, chat, etc.

Redirect your calls

Redirecting your calls is especially important for mobile work. This can be achieved via two options:

1. Enable the redirect directly on your Cisco device (on site in your office)
2. Enable the redirect remotely via the Cisco user portal (via remote access)

Note: A leading "0" needs to be put in front of the external phone number. E.g. if your number is 03731 123456, this converts to 003731 123456


Conference calls

Web Conference: BigBlueSystem

The BPS Bildungsportal Sachsen GmbH provides the conference system BigBlueButton to all Saxonian universities. This system is primarily designed for E-Learning purposes:

  • Select your institution (in this case TU Bergakademie Freiberg) and log in with your central login.
  • You will find ten available rooms. You may enter your desired room either as a participant or a moderator.
  • At first you will be prompted to check your microphone, afterwards you may also enable your webcam.
  • The system also enables you to chat with other participants or share your screen.

Note: If you are using Windows 10 LTSB or LTSC the use of your microphone and webcam are blocked by a group policy, which can be changed as described here.

Video Conference: DFNconf

You can set up telephone or video conferences via DFNConf. 

Note: If you are using Windows 10 LTSB or LTSC the use of your microphone and webcam are blocked by a group policy, which can be changed as described here.

Phone conference: Cisco telephone

You can start conference calls from a Cisco telephone. All other participants can join externally. The initiator chooses the first participant. As soon as the connection is established, the initiator presses the conference key. Then the next participant is selected and the conference partner is added.

Participants can also release themselves from the conference by pressing the transfer key (softkey below the display). This scenario is conceivable if e.g. Participant A started the conference, but Participant B should ultimately lead it.

Note: Due to system limitations, a maximum of ten participants are possible.

Video Conference: NextCloud Talk

In order to conduct team meetings or online consultations you may use OwnSky Cloud: Talk.

You can show current talks, join them and use the recorded chat function. Due to the peer-to-peer architecture of this system it can only be used by smaller groups.

Note: If you are using Windows 10 LTSB or LTSC the use of your microphone and webcam are blocked by a group policy, which can be changed as described here.


Chat

Chat via NextCloud Talk

In order to conduct text-based team meetings or online consultations you may use OwnSky Cloud: Talk. You can also share your screen.

Chat via Jabber-Client

You may alternatively use the Cisco Jabber-Client for chatting. Once both/all participants have installed and activated the client you have the option for single or group chats.

How to connect via VPN?

Access to the network

Some services are only accessible internally and require a vpn connection to access them externally.

VPN required for the following scenarios

  • Access to the intranet
  • Access to the application server
  • Access to university library online resources (publishers)
  • Use of Cisco Jabber

You can access our data network in various ways:

You can access our network in various ways

Use the correct VPN profile

Various profiles are available for dialing into the VPN:

  • xSplit:
    Only data traffic into the TUBAF network is sent via the VPN tunnel, other (internet) data traffic is routed via locally available networks.
  • xSplitSSLonly:
    Analogous to "xSplit", but the data traffic is only encrypted with TLS (in case connection problems occur with some Internet providers).
  • world:
    All data traffic is sent via the VPN tunnel (especially necessary to access the library's online resources).
  • xSSLonly:
    Analogous to "world", but the data traffic is only encrypted with TLS (if connection problems occur with some Internet providers).

Note: Please use the "xSplit" or "xSplitSSLonly" tunnel as far as possible to conserve our VPN resources. With these profiles, data traffic to the Internet can take place via private Internet access and does not place an additional burden on the VPN network.


Access partially possible without vpn connection

You do not necessarily need to dial in via vpn for anumber of services. Therefore, please try to limit the VPN connection to the bare minimum in order to ensure that all university members can have sufficient access.

Home directory without VPN

The home directories can be integrated via our OwnSky cloud service and thus accessed via the web browser.

Receive and send e-mails without VPN

You can easily access and send emails via the Horde or Webowa web services.

You can also use common email clients (e.g. Outlook, Thunderbird) without a VPN connection. We have also prepared instructions for this:
