Determining the Correct FLEXnet hostid for Synopsys Licensing

Question:

How can I determine the correct FLEXnet hostid for my new license server?

Answer:

For a given OS / hardware platform, there are multiple ways to determine the hostid. However, not all methods are valid with the FLEXnet licensing scheme implemented by Synopsys.

For every major platform, this article provides two methods for obtaining a valid hostid for Synopsys licensing.

Note:

If your keyfile has already been issued for the wrong hostid, your keys will need to be reissued. In some cases, you will also be required to obtain and sign a "rehost form."

• Use the lmutil lmhostid command included with SCL.

      % lmutil lmhostid
      lmhostid - Copyright (c) 1989-2006 Macrovision Europe Ltd....All Rights Reserved.
      The FLEXlm host ID of this machine is "001125c4a904"

  If you do not have the lmutil binary for your platform, you can download lmutil directly from Acresso Software.

• In addition to lmutil, the following platform-specific methods of determining a hostid are supported. For all the methods below that involve quotes, be sure to use backquotes ( ` ) and not regular quotes.
  • AIX
  • HP-UX
  • IRIX
  • Linux
  • Solaris (SPARC)
  • Windows 2000, XP

uname -l and convert to hexadecimal:

% echo `/bin/uname -l` 16op | dc [the "l" in "-l" and the "o" in "16op" are both letters] 8CC6F4C [result should be seven or eight characters]

Note:

The hostid and uname -m commands produce invalid results

uname -i and convert to hexadecimal:

% echo `/bin/uname -i` 16op | dc [the "o" in "16op" is a letter] 77ED1331 [result is always eight characters]

Note:

For HP-UX 11.11 (11i) or later, the lanscan command is not supported (ethernet hostid is invalid).

For HP-UX 11 and earlier versions, the lanscan command produces a result that is not recommended.

echo `/etc/sysinfo -s` and convert to hex from decimal Example:

% echo `/etc/sysinfo -s` 16op | dc [the "o" in "16op" is a letter] 690bf2d6

Get the 12-character ethernet address Example:

% /sbin/ifconfig -a | grep Hwaddr eth0... Hwaddr 00:06:5B:82:F4:5A [result is always 12 characters]

In this example, the hostid is 00065B82F45A

Note:

The Linux "hostid" command produces a 6- or 8-character result that is not valid as a Synopsys hostid.

% /usr/bin/hostid 80752FAE [result is always eight characters]

Floating (networked) licenses Use the MAC address ("Physical Address") of your ethernet card:

1. Click Start-Run and type "cmd"
2. Type C:\winnt\system32\ipconfig -all

Result:

Ethernet adapter Local Area Connection:

   Connection-specific DNS Suffix:
   Description . . . . . . . . . : 3Com 3C920 Fast Ethernet
   Physical Address. . . . . . . : 00-06-5A-21-95-44

==> In this example, the hostid is 00065A219544

Dongle-based (nodelocked) licenses

Dongle-based licenses are available only on Windows platforms. Dongle-based licenses are usually nodelocked--that is, the application (for example, HSPICE) can be run only on the system that has the dongle device.

If you have a dongle, the hostid is written on the device, which attaches to the parallel port. (USB dongles are not officially supported. If you wish to use a USB dongle, contact your local Synopsys Support Center.) To determine whether the dongle hostid is correctly detected, enter:

    cd C:\synopsys\SCL_10.9.3\msvc70\bin
    lmutil lmhostid -flexid

Result:

C:\synopsys\SCL_10.9.3\msvc70\bin>lmutil lmhostid
