Virtual Machines

tmgsim1.sl.tmg.loc - Windows 7

Quad Core, 6 GiB Ram. 32 GB Disk, transparent access to AFS Storage.

Installation

Example walkthrough with a windows machine: 

Windows 7 Professional 64 bit,  english
Internal name: win7sim1
Manually set IP Address to 172.29.22.201 / 16 on the first run.  Update 07.2011: DHCP delivers 192.168.22.61
Because this would NOT work with Qualnet (only 172.22./16 as client address range has been bought) switch to bridged mode and to DHCP with DNS tmgsim1.tmg.loc

Disable IPv6
Enable ICMP in Firewall
<reboot>
Enable Remote Desktop with "any version"

Install Firefox

Microsoft: 2 Important Updates
<reboot>
Microsoft: 62 (!) Important Updates in several steps
<reboot>
Install Notepad++ 5.8.7
Install Updatechecker 1.038
Firefox: Prefbar 

Activate Windows. Licenses are available  from MSDNAA

Install KfW 3.2.2 32bit + 64bit
Install Network Identity Manager 2.0.102 32bit + 64bit
Install OpenAFS 1.5.78 64bit

Change Computer Name --> UG-UMINTMGSIM1 to join Active Directoy
(The DNS Name stays tmgsim1.tmg.loc though!) Update 07.2011: tmgsim1.sl.tmg.loc
Join Active Directory (one needs to be a Domain Admin to do so)

Granted Remote Desktop manually (no groups mechanism available in AD for this task) access to:

  • akellne
  • oalfand
  • shartung
  • staheri
  • yelhajj
  • geyu -- local user account, no Admin. (Local due to problems with UG-STUDENT.)
  • uburgha
  • gtest2 -- user only, no Admin
  • c.wehrberger
  • pmemarm

I've put these five user accounts into group ADMINISTRATORS! This way it is possible to log in with gwdg\username also for administrative tasks.

Please note that only one single user can run a Remote Desktop session at any given time. If you want to share a single virtual machine you need to create yourself a schedule...

Installed Qualnet 5.0.1 connected to license server. Tested usage from a remote site as described below.

Multiple-User access

  • it is possible to run applications in the background without being logged in: you may close the Remote Desktop window and leave everything running!
  • ONLY ONE user can have an established Remote Desktop connection at any given point in time.
    • when a second user tries to connect the first one will get a message box.
    • the first user has the priority. He may simply deny lo loose his connection.
    • if that first user is not watching his terminal then an automatically implied answer is "yes, loosing the connection is ok for me"!
  • there are ONLY TWO Qualnet licenses. You need to talk with each other to schedule usage of these.

Remote Access from outside

The system is reachable only from inside the Institute's LAN.

The Remote Desktop inside the guest is configured in the default manner, listening on standard port 3389.

You may login to login.informatik.uni-goettingen.de (Staff only. Students and staff may use login.stud.informatik.uni-goettingen.de) and forward any unused local port (e.g. 12345) to 

tmgsim1.sl.tmg.loc:3389   (Updated 07.2011)

The result is the same: with this tunnel established it is possible to use the standard Remote Desktop application to connect to localhost:12345.

For Linux run something like this: 

~$ rdesktop  -u gwdg\\username  -g1200x1000  -a16   localhost:12345

Updates

Someone should be responsible for keeping the system up-to-date!
