MATLAB Installation Guide for Unix

Determining Your Hostid

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

• 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 hostid.

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

Hardware Platform	Hostid Description	How to Obtain the Hostid	Sample Hostid
Sun SPARC	32-bit hostid	Enter the hostid command.	170a3472
HP 9000	32-bit hostid	echo `uname -i` 16o p | dc	778DA4550
Compaq 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 hostid you must remove all colons (:) and prefix any single-digit parts of the address with a zero (0). For example, the hostid for the address above would be 08002be68759.	08002be68759
SGI	32-bit hostid	echo `/etc/sysinfo -s` 16o p | dc On systems with multiple CPUs, use the first hostid.	90D40225
IBM RS/6000	32-bit hostid	Enter the uname -m command. Remove the last two digits and use the lowest eight digits, ignoring any high level zeros.	00249477
Linux	Ethernet address	/sbin/ifconfig eth0 Use 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 hostid you must remove all colons (:) and prefix any single-digit parts of the address with a zero (0). For example, the hostid for the address above would be 08002be68759.	08002be68759
