INTERNAL: How to locate the HostID

David Blackston
If you have not yet installed ENVI or IDL on your computer you will find the article helpful in determining how to find the 'hostid' of your operating system. This information is typically required when requesting a new license or when moving a license to another machine.

If you have already installed ENVI or IDL you can use the License Wizard or LMTools.

To determine the correct HostID for the operating system in question use the following commands:

Windows
    Start>Run and type in: cmd

    At the command prompt type in: ipconfig /all

    The HostID is the 'Physical Address' of the first Ethernet adapter listed, with the dashes (-) removed.

Linux

    /sbin/ifconfig eth0

    Use the string to the right of HWaddr and remove the colons (:).

Note:
If the Linux machine is using a network interface named eth1 (because the system only has one LAN ethernet card) it will be necessary to rename the interface as eth0.

Mac OS X

    Open the Apple System Profiler application in /Applications/Utilities. Look in the Network overview of the System Profile to find the Mac's Ethernet Address.
    For example: 6.0.1b.e7.65.58

    This command can also be used: netstat -I en0
    For 10.6 and above:

    Head into System Preferences, then click on Network, then double-click on Ethernet or Airport depending on which address you are attempting to obtain. Once open, click on the "Advanced" Button, and then the "Ethernet" or "Airport" tab where you will find the Host ID listed as the Ethernet ID or Airport ID.

Solaris

    hostid

Unix
Browse to the IDL/bin directory and issue the following command:

    ./lmhostid
