• Antelope Release 5.10 Linux CentOS release 7.6.1810 (Core) 3.10.0 2020-05-12

 

NAME

amd - Server for returning system identifier

SYNOPSIS

amd [-ver] [-v] [-l logfile]

DESCRIPTION

The amd program is used to retrieve a system identifier for purpose of licensing. This program is statically linked, does not require an Antelope license to run and does not depend in any way on the Antelope distribution. Currently, the only version of amd is for Linux hosts since the system serial number is readily available under MacOSX without the need for a server process. Under Linux, starting with RHEL/CentOS version 7, there is no way to get the system serial number without root permission. amd is a TCP server that is hardwired to run only on the loopback address on a fixed port. amd needs to be run with root permission and is typically started as a daemon process at boot time through the startup script installed by install_boot_scripts(1). Once amd is running under root permission, then any Antelope process can obtain the system identifier on that host through an encrypted communication pipe from amd. This allows node based licensing for Linux systems running RHEL/CentOS 7+.

The amd daemon also allows node licensing based upon USB keylok dongle devices. These devices provide unique serial numbers that can be used to license Antelope processes in the same manner as system serial numbers, which can be used with certain limitations to enable RHEL/CentOS virtual machines to run under keylok dongle based node licenses, i.e. without the need for ip-based licenses.
