GLOBE Claritas Ethernet Based Licencing

The Globe Claritas license is tied to the ethernet address of your computer. The ethernet address is a 12-character string, usually split into six pairs separated by hyphens or colons. For example : 03-DF-E0-1A-98-B1 or 03:DF:E0:1A:98:B1. There are various ways to find what this address is on your computer, and your system manager might already have the information.

There is a failsafe method which requires you to log on to the GNS ftp site and download a small Unix programme (called printlan) which prints out the Local Area Network ID and the ethernet card address to your screen. To get and run printlan:

% ftp ftp.gns.cri.nz
ftp> (log on as anonymous, supply e-mail address as password)
ftp> cd pub/claritas/
ftp> dir (to list available directories)
ftp> cd Linux (or Solaris, AIX, DECOSF)
ftp> binary (set binary transmission mode)
ftp> get printlan
ftp> quit
% chmod +x printlan (make the file executable)
%./printlan (run printlan)

If you have any problems please don't hesitate to let us know.

Linux users can also log on to their systems as root user and type the Unix command "ifconfig -a" - there will be a line similar to : "eth0 Link encap:Ethernet HWaddr 00:C0:F0:17:20:25".
