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. In the table, note that the license manager uses different hostid formats for different hardware platforms because 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. An Ethernet address is 6-bytes long and each byte is specified as two hex digits. Specify all 12 hex digits when using an Ethernet address as the hostid. For example, if the Ethernet address is 8:0:20:0:5:AC, specify the hostid as 0800200005AC.

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 Ethernet address	echo `uname -i` 16o p | dc lanscan (use station address without leading 0x).	778DA4550 070020005532
Compaq Alpha	Ethernet address	/usr/sbin/netstat -i Look under address and remove all colons (:) from the entry associated with ln0.	080020005532
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 string to the right of HWaddr and remove all colons (:).	00400516E525
