Version vom 6. August 2013, 14:24 Uhr
Repetition of some well known facts and a standard procedure:
- local computers are not reachable from the outside world as this is the definition of "local"
- all our "normal" LANs uses subnets in several sub-ranges of
172.16.0.0/12. E.g. Telematic uses172.22.0.0/16 - the Sensor Lab's net is behind a local router
172.22.255.253) and uses a private network192.168.22.0/24 - standard protocol to access local machines from outside is SSH
- to reach (for example)
tmgsim1.sl.tmg.locyou need to login to a public server first and then connect to the final destination
Accessing a virtual Windows Desktop from a local Windows machine
tmgsim4.tmg.locis running Windows 7
Please note that this machine is not located in the Sensor Lab Network because of limitations of the available license for Qualnet.
~$ host tmgsim4.tmg.loc tmgsim4.tmg.loc has address 172.22.98.204
Use the login server (login.stud.informatik.uni-goettingen.de) and establish Port Forwarding of an arbitray /unused local port (e.g. 12345) to port 3389 on that target machine using PuTTY.
For reference: the unix command line looks like this:
ssh -L 12345:tmgsim4.tmg.loc:3389 username@login.stud.informatik.uni-goettingen.de
In PuTTY you need to go to Connections --> SSH --> Tunnels and fill Source Port with 12345 and Destination with tmgsim4.tmg.loc:3389. After pressing "Add" the result is one line in the "Forwarded Ports" list reading:
L12345 tmgsim4.tmg.loc:3389
Now you can connect with rdesktop (Linux) or "Remote Desktop Connection" (Windows) to
localhost:12345
You will get a windows login screen. Log in with your credentials in the usual form, e.g. UG-STUDENT\username or GWDG\username
Please note the number of licenses is small, so you might not be able to use Qualnet.
Successfully verified: Eduroam/WLAN --> login.stud --> rdesktop --> Qualnet. Udo, 05.10.2011
