Determining Your Host ID

If MATLAB is already installed, there are two ways to determine your server host ID:

Log in to the computer where you run the license manager and run the script lmhostid in the $MATLAB/etc directory.
Start MATLAB and enter the hostid command at the MATLAB prompt.

If MATLAB is not installed, use a native operating system command to find the host ID.

The following table lists the operating system commands you can use to determine your host ID for each supported system. Some hardware platforms, such as Sun, have a unique host ID, while others do not. For this reason, the Ethernet address is used on some platforms as the unique host ID.

Hardware Platform
Host ID Description
How to Obtain the Host ID
Sample Host ID

Sun SPARC
32-bit host ID
Enter the hostid command.
170a3472

HP 9000
32-bit host ID
echo `uname -i` 16o p | dc
778DA4550

Alpha
Ethernet address
/usr/sbin/netstat -iIn the output from this command, look in the Address column for a colon-separated, hexadecimal number, such as 8:0:2b:e6:87:59.
Note: To use this address as a host ID you must remove all colons (:) and prefix any single-digit parts of the address with a zero (0). For example, the host ID for the address above would be 08002be68759.
08002be68759

SGI
32-bit host ID
echo `/etc/sysinfo -s` 16o p | dc
On systems with multiple CPUs, use the first host ID.

IBM RS/6000
32-bit host ID
Enter the uname -m command. Remove the last two digits and use the lowest eight digits, ignoring any high level zeros.

Linux
Ethernet address
/sbin/ifconfig eth0Use the colon-separated, hexadecimal number to the right of HWaddr, such as 8:0:2b:e6:87:59.
Note: To use this address as a host ID you must remove all colons (:) and prefix any single-digit parts of the address with a zero (0). For example, the host ID for the address above would be 08002be68759.
08002be68759

Mac OS X
Ethernet address
Open the Apple System Profiler application in /Applications/Utilities. Look in the Network overview of the System Profile.
You can also use the command:
netstat -I en0
assuming en0 is the Ethernet interface. Use the period-separated, hexadecimal number, such as 8.0.2b.e6.87.59.
Note: To use this address as a host ID you must remove the periods (.) and prefix any single-digit parts of the address with a zero (0). For example, the host ID for the address above would be 08002be68759.
08002be68759

Hardware Platform	Host ID Description	How to Obtain the Host ID	Sample Host ID
Sun SPARC	32-bit host ID	Enter the hostid command.	`170a3472`
HP 9000	32-bit host ID	echo `uname -i` 16o p \| dc	`778DA4550`
Alpha	Ethernet address	`/usr/sbin/netstat -i`In the output from this command, look in the Address column for a colon-separated, hexadecimal number, such as `8:0:2b:e6:87:59`. Note: To use this address as a host ID you must remove all colons (`:`) and prefix any single-digit parts of the address with a zero (0). For example, the host ID for the address above would be `08002be68759`.	`08002be68759`
