The information on this page refers to LM-X v4.6 or newer, which added the IGNORE_BORROW_LIMIT_COUNT and IGNORE_BORROW_LIMIT_HOURS settings. These settings are not available in previous versions of LM-X. 

The vendor may supply a license server configuration file, named lmx-serv.cfg by default. This configuration file is an ASCII text file, which can be opened and modified using any text editor. You may replace the existing information in the configuration file as needed.

For example, assume we are using a floating license. This type of license allows any number of users to have the software installed, but only a certain number of users to use the software simultaneously. When all allotted licenses are in use, other users must wait until a license becomes available to use the software. If you want to use software licenses most efficiently and implement fair/desired distribution of licenses, then as an administrator of the LM-X server, you may set the following options in the LM-X License Server configuration file: 

  • Permissions. Setting permissions lets you allow or deny individual users/groups use of the license server according to your organization's specific needs. Permissions can be based on a set of rules that include permissions for normal checkouts as well as license borrowing. 

  • Reservations. You can reserve a specified number of licenses that can be used by individual users or groups. Reservations can also be done using a set of rules, allowing you to specify the reservation order. Some users or groups can be given higher priority than others.

  • Limitations. You can limit the number of licenses that can be used by individual users or groups. Limitations can be done by a set of rules. In particular, limiting of users is done by a first match rule, so if a user belongs to more than one group specified in restrictions, the first restriction will apply to that user.

The configuration file includes instructions for using each setting in the file, which may include the following, depending on the options provided by your vendor. Some of the configuration settings can also be specified using the web-based UI, as described in Administration.

Syntax

Description

Examples

TCP_LISTEN_PORT = port number

The TCP port number the license server will listen on.

  • TCP port is used for data traffic protocol. The default TCP port is 6200.
  • UDP port is used for automatic server discovery protocol. The UDP port is fixed to 6200 and cannot be changed. See http://www.iana.org/assignments/port-numbers for more information.

TCP_LISTEN_PORT = 6200

TCP_BIND_ADDRESS = IP_address_1 IP_address_2

Limit which networks the license server allows for client connections.  

When this setting is specified, the license server will only accept clients that connect from a network that uses the specified IP addresses. You can specify only one address for each IP version (one for IPV4 and one for IPV6).

This setting is useful when the license server is connected to more than one network (has more than one IP address) and you want to limit allowed connections based on which network the client is on.

When this setting is unspecified, the license server accepts clients from all available networks.

TCP_BIND_ADDRESS = 192.168.21.321 8000:8000:8000:8000:abcd:1234:12df:fd54

HAL_SERVERserver_number = [port]@hostname
or
HAL_SERVERserver_number = [port]@IP_address

Note: Port is optional.

High Availability Licensing (HAL) servers, which enable redundant servers, so if one server goes down, two others will still work. HAL consists of 3 specified servers, at least 2 of which must be up and running at all times.

Each HAL_SERVER line indicates a license server that has HAL enabled by its license(s). Each HAL server has a specific role, and should be specified in terms of how many resources each server has:

  • HAL_SERVER1 is your master server, which allows both CHECKOUT and BORROW. HAL_SERVER1 should be your most powerful server.
  • HAL_SERVER2 is your first slave server, which allows CHECKOUT but denies BORROW in the event that your master server goes down. HAL_SERVER2 should be your second most powerful server.
  • HAL_SERVER3 is part of your configuration to ensure that everything works as expected, and does not allow any CHECKOUT or BORROW requests. HAL_SERVER3 should be your least powerful server.
    Important: The HAL_SERVER list must be identical on all your servers for HAL to function properly

HAL_SERVER1 = 6200@server1
HAL_SERVER2 = 6200@server2
HAL_SERVER3 = 6200@server3

LOG_FILE = path

The log file path. Specifying the full path is preferred.

If you do not specify this setting, the default is used: On Windows the default is lmx-serv .log, under the license server directory. On Unix, the default location for the log file is in the directory from which the license server was started

LOG_FILE = c:\program files\lmx-server.log
LOG_FILE = /home/user1/lmx-serv.log

LOG_FORMAT = NORMAL or EXTENDED

The format for the log file.

The default setting for the log file format is NORMAL.

Specifying EXTENDED causes additional information to be included in the log file, such as license server HostIDs, whether the license server is a virtual machine, etc. Setting the log file format to EXTENDED is particularly useful for debugging purposes.

LOG_FORMAT= NORMAL
LOG_FORMAT=EXTENDED
 

LOG_EXCLUDE = message1, message2, etc.

Exclude messages from the log. The following messages can be excluded: CHECKOUT, CHECKIN, STATUS, BORROW, BORROW_RETURN, REMOVE_USER, REMOTE_RESTART or REMOTE_SHUTDOWN.

LOG_EXCLUDE = CHECKOUT, CHECKIN, STATUS

LOGFILE_ROTATE_INTERVAL = rotation_interval

The interval for log file rotation.

The value may be set to "day" (every day at midnight), "week" (every Monday at midnight), or "month" (the first day of every month at midnight).

After rotation, the old log file will be named filename.log.rotation_date in the format yyyy-mm-dd.

A message indicating the location of the rotated log file is added to the end of the old log file and the beginning of the new log file, as follows:

"Log file was rotated and saved to filename."

LOGFILE_ROTATE_INTERVAL = day

MIN_USER_REMOVE_TIME = time in seconds

Minimum time, in seconds, that must elapse from the connection before a user can be removed using lmxendutil.

The specified time must be equal to or greater than the number of seconds specified by your application vendor. Default minimum time is 120 seconds. If the time is set to -1, user removals will not be allowed.

MIN_USER_REMOVE_TIME = 120

LICENSE_FILE = path

The license file path.

On Windows: If no file is set, the license server will look for vendor.lic in the same directory as the license server.

On Unix: If no file is set, the license server will look for /usr/x-formation/vendor.lic.

In both cases, the filenames must be lowercase. You can specify one or multiple paths as needed.

LICENSE_FILE = d:\server\network.lic
LICENSE_FILE = c:\extra_file.lic
LICENSE_FILE = /home/user1/floating_license.lic
LICENSE_FILE = /home/user1/floating_license2.lic

USAGE_DATABASE = database path

Pay-per-use usage database (used for billing purposes). See Pay Per Use feature for detailed information, including database format and an example of data printout.

USAGE_DATABASE = d:\server\usage.db
USAGE_DATABASE = /home/user1/usage.db

USAGE_LEVEL= detail level

Specify pay-per-use detail level.

  • STANDARD includes basic usage information.
  • DETAILED includes user information in addition to the basic usage information.

USAGE_LEVEL = STANDARD

USAGE_WRITE_INTERVAL= number of actions

Specify the number of pay-per-use actions (checkouts, checkins, etc.) after which pay-per-use records will be written to the pay-per-use database file. The default setting is 1000.

USAGE_WRITE_INTERVAL = 1000

REMOTE_ACCESS_PASSWORD = password

Remote administration password (used when remotely stopping and restarting the license server and removing users from it).

The password is case-sensitive.

REMOTE_ACCESS_PASSWORD = MyPassword123

FAST_QUEUE = feature1, feature2, etc.
or
FAST_QUEUE = ALL

Fast queuing allows requests that can be fulfilled immediately to be fulfilled.

For example, if a client is waiting for two licenses, and only one license is immediately available, another client that needs only one license can bypass the queue and take the single license without waiting.

Default behavior of license queuing is to put the client at the end of the queue regardless whether the license request could be satisfied.

FAST_QUEUE = f2, d5, app2

ALLOW_IPADDR_ALL = one or more IP addresses

ALLOW_IPADDR_feature name = one or more IP addresses (must be either specific A.B.C.D or with wildcards; e.g., A.B.*)

DENY_IPADDR_ALL = one or more IP addresses

DENY_IPADDR_feature name = one or more IP addresses (must be either specific A.B.C.D or with wildcards; e.g., A.B.*)

ALLOW_HOST_ALL = one or more hosts

ALLOW_HOST_feature name = one or more hosts

DENY_HOST_ALL = one or more hosts

DENY_HOST_feature name = one or more hosts

ALLOW_USER_ALL = one or more users

ALLOW_USER_feature name = one or more users

DENY_USER_ALL = one or more users

DENY_USER_feature name = one or more users

Note: For host, you can use a hostname or use "localhost" to specify the current machine. For IP address, you can specify a complete address (A.B.C.D) or use wildcards; e.g., A.B.*).

Allow/deny specific clients from using the license server.

The allow/deny rules work as follows:

  • Rules are attempted to be matched in the order they are written.
  • If no rule matches the specific client, then that client is allowed.
     

The following example will allow clients on only 2 subnets, user Administrator and root from any host and deny everyone else. This applies to all features.

ALLOW_IPADDR_ALL = 192.168.1.* 192.168.2.*
ALLOW_USER_ALL = Administrator root
DENY_IPADDR_ALL = ...

The following example will deny clients on localhost, deny the machines with hostname 'untrusted' and 'crackerjack', allow clients on the internal network, and deny everyone else. This applies to the feature f2.


DENY_HOST_f2 = localhost untrusted crackerjack
ALLOW_IPADDR_f2 = 192.168..
DENY_IPADDR_f2 = ...

ALLOW_BORROW_IPADDR_ALL = one or more hosts

ALLOW_BORROW_IPADDR_feature name = one or more hosts

DENY_BORROW_IPADDR_ALL = one or more hosts

DENY_BORROW_IPADDR_feature name = one or more hosts

ALLOW_BORROW_HOST_ALL = one or more hosts

ALLOW_BORROW_HOST_feature name = one or more hosts

DENY_BORROW_HOST_ALL = one or more hosts

DENY_BORROW_HOST_feature name = one or more hosts

ALLOW_BORROW_USER_ALL = one or more users

ALLOW_BORROW_USER_feature name = one or more users

DENY_BORROW_USER_ALL = one or more users

DENY_BORROW_USER_feature name = one or more users

Note: For host, you can use a hostname or use "localhost" to specify the current machine. For IP address, you can specify a complete address (A.B.C.D) or use wildcards; e.g., A.B.C.*).

Allow/deny specific clients from borrowing licenses.

The following example will allow the specific users, and deny host and IP addresses on the list from borrowing any feature. Everyone else will be allowed.

ALLOW_BORROW_USER_ALL = daisy harry tom
DENY_BORROW_HOST_ALL = server1 machine5
DENY_BORROW_IPADDR_ALL = 192.168.3.* 192.168.4.*

The following example will allow the specific users and deny everyone else from borrowing f2.

ALLOW_BORROW_USER_f2 = lazyjack rabbit joeuser
DENY_BORROW_IPADDR_f2 = *...*

LIMIT_USER_feature name___limit count = one or more users
LIMIT_HOST_feature name___limit count = one or more hosts
LIMIT_IPADDR_feature name_limit count = one or more hosts

Note: For host, you can use a hostname or use "localhost" to specify the current machine. For IP address, you can specify a complete address (A.B.C.D) or use wildcards; e.g., A.B.C.*).

Limit the number of licenses that can be used by individual users or groups to implement fair/desired distribution of licenses.

Limiting of users is done by a first match rule, so if a user belongs to more than one group specified in restrictions, the first restriction will apply to that user.

LIMIT_USER_f2_5 = harry joe sam
LIMIT_IPADDR_f3_3 = 192.168.2.* 192.168.4.*

RESERVE_USER_feature name___reserve count = one or more users
RESERVE_HOST_feature name___reserve count = one or more hosts
RESERVE_IPADDR_feature name_reserve count = one or more hosts

Note: For host, you can use a hostname or use "localhost" to specify the current machine. For IP address, you can specify a complete address (A.B.C.D) or use wildcards; e.g., A.B.C.*).

Reserve a number of licenses that can be used by individual users or groups to implement fair/desired distribution of licenses.

Reservation of users is done by a first match rule, so if a user belongs to more than one group specified in the rules, the first rule will apply to that user.

RESERVE_USER_f2_5 = harry joe sam
RESERVE_IPADDR_f3_3 = 192.168.2.* 192.168.4.*

BORROW_LIMIT_COUNT_ALL = limit count
BORROW_LIMIT_COUNT_feature name = limit count

IGNORE_BORROW_LIMIT_COUNT_USER_feature name = one or more users

IGNORE_BORROW_LIMIT_COUNT_HOST_feature name = one or more hosts

IGNORE_BORROW_LIMIT_COUNT_IPADDR_feature name = one or more IP addresses


Note: You can use IGNORE_BORROW_LIMIT_* flag to whitelist small and specific predicates blacklisted by broader BORROW_LIMIT_* predicate.

Limit/Do not limit the number of licenses that can be borrowed to prevent all licenses from being borrowed at the same time.


BORROW_LIMIT_COUNT_f2 = 1
BORROW_LIMIT_COUNT_ABCDEF = 5

The following example will allow the user ADMIN, and deny host and IP addresses on the list from borrowing more than 100 features.

BORROW_LIMIT_COUNT_F1 = 100

IGNORE_BORROW_LIMIT_COUNT_USER_F1 = admin

IGNORE_BORROW_LIMIT_COUNT_HOST_F1 = server

IGNORE_BORROW_LIMIT_COUNT_IPADDR_F1 = 192.168.1.*

BORROW_LIMIT_HOURS_ALL = limit hours
BORROW_LIMIT_HOURS_feature name = limit hours

IGNORE_BORROW_LIMIT_HOURS_USER_feature name = one or more users

IGNORE_BORROW_LIMIT_HOURS_HOST_feature name = one or more hosts

IGNORE_BORROW_LIMIT_HOURS_IPADDR_feature name = one or more IP addresses

Note: You can use IGNORE_BORROW_LIMIT_* flag to whitelist small and specific predicates blacklisted by broader BORROW_LIMIT_* predicate.

Limit/Do not limit the number of hours licenses can be borrowed to prevent licenses from being borrowed for too long.


The following example will allow the specific users, and deny host and IP addresses on the list from borrowing any feature. Everyone else will be allowed.

BORROW_LIMIT_HOURS_f2 = 1
BORROW_LIMIT_HOURS_ABCDEF = 5

The following example will allow the user admin, and deny host and IP addresses on the list from borrowing more than 100 features.

BORROW_LIMIT_HOURS_F1 = 10

IGNORE_BORROW_LIMIT_HOURS_USER_F1 = admin

IGNORE_BORROW_LIMIT_HOURS_HOST_F1 = server

IGNORE_BORROW_LIMIT_HOURS_IPADDR_F1 = 192.168.1.*

FEATURE featurename
{
feature settings
}

Specify licenses directly within the configuration file to eliminate the need to have both a license file and configuration file for the license server. You can specify any features from one or more license files.

The content must be specified within the _START_LICENSE_ and _END_LICENSE_ clauses.

_START_LICENSE_
FEATURE F1
