Rdesktop vs. temporary client licenses
Mon, 2007.04.16 - 21:26 — müzso
If you connect with rdesktop to a Windows 2003 Terminal Server, then you cannot use a TSCAL (Terminal Services Client Access License). The server automatically assigns a temporary license to your client that is valid for 90 days. You can cheat on this by using the
"-n <hostname>" switch. The server assigns the license based on the hostname that your rdesktop client sends during the build up of the connection, so by changing it you can "renew" your temporary license a virtually indefinite number of times. You can use any sort of hostname, it does not have to be a valid hostname on your network.

How to?
Thanks for your help!
Re: How to?
Check out it's website.
Rdesktop is available in most linux distros or can be easily compiled from source. On Mac OS X you can install it with Darwin Ports or Fink (I've just tried the latter on a 10.6.4 Mac and it compiled without errors and worked just fine with a Win2003 Server). You should have X11 installed from the Mac OS X DVD, because rdesktop will run in an X11 window.
The
-nswitch is for rdesktop. You start rdesktop from a Terminal using a commandline like this:rdesktop some.server.comTo specify the screen size and the client hostname switch, you can use something like this:
rdesktop -g 1024x768 -n "somerandomstring" some.server.com:3389
