Configure ArcGIS License Manager to work through a firewall

  • Procedure

Many of today's networks use a firewall for enhanced security from outside threats. Because the license manager uses the TCP/IP protocols, implementing such a firewall can pose problems between the license manager server and the clients connecting to it.

The problem is caused by the firewall often closing or blocking access to the ports the license manager uses to communicate. By default, the lmgrd daemon is set to port 27000. The ARCGIS daemon, on the second line of the file, is not confined to a particular port range. It is dynamic, meaning that it can listen on any available port.

To secure the license management environment and allow you to implement a firewall, you can lock the ARCGIS daemon to a specific port. You can also change the lmgrd daemon from the default 27000 to another port between 27000 and 27009. This range was prespecified for license manager use because of the low traffic in that range.

Procedure

The steps provided require that you briefly stop the license manager. During this time, connections to the license manager may be lost.

  1. Click Start > Programs > ArcGIS > License Manager > License Server Administrator.
  2. Click Start/Stop License Server in the table of contents and click Stop.
  3. Open Windows Explorer and navigate to your license manager installation location (C:\Program Files\ArcGIS\License10.3\bin by default), in which you will see a service.txt file.

    The file should look similar to this:

SERVER this_host ANY 27000
VENDOR ARCGIS
USE_SERVER
FEATURE ACT ARCGIS 1 permanent 1 vendor_info=7KNJDRHFHBK4CFDMJ214 SIGN="052E ABFC 32DD \
	2473 DEFD E276 4BF3 E0DB 87EB 2203 5A30 C014 19A1 C35E 2154 \
	08B1 9460 A2B9 6701 DC4D CAF2 E2FE 1347 0E36 90FA 4F3B E864 \
	BEC8 D3A2 A615"

At the end of the SERVER line, you can choose to specify a port number immediately after ANY.

On the VENDOR line, add PORT=####, where #### is a specific port number designated by you, to lock the vendor daemon to that specific port (for example, 1234). After making the changes, your service.txt file should look something like this:

SERVER this_host ANY 27004		
VENDOR ARCGIS PORT=1234
USE_SERVER
FEATURE ACT ARCGIS 1 permanent 1 vendor_info=7KNJDRHFHBK4CFDMJ214 SIGN="052E ABFC 32DD \
	2473 DEFD E276 4BF3 E0DB 87EB 2203 5A30 C014 19A1 C35E 2154 \
	08B1 9460 A2B9 6701 DC4D CAF2 E2FE 1347 0E36 90FA 4F3B E864 \
	BEC8 D3A2 A615"

  1. Save the .txt file.
  2. From License Server Administrator, click Start.

    The vendor daemon is now static, locked to the port specified.

  3. These ports can now be saved as exceptions in the firewall to allow communication between the license server and the client.
Note:

With ArcGIS License Manager 10.3-10.3.1, a specific port in the range 27000-27009, must be specified for the lmgrd daemon as a requirement for configuring it for use with a portal. The service.txt file found in the install directory (..\Program Files\ArcGIS\License10.3\bin by default) will now include the port 27000 by default after installing ArcGIS License Manager. If ArcGIS License Manager 10.3 was installed as an upgrade from an earlier version, for example over ArcGIS License Manager 10.2.2 and a port such as 27004 was already specified in the earlier install, this port may not be carried over into the new install. In this case, the port will need to be manually re-entered into the service.txt file. If upgrading from ArcGIS License Manager 10.3 to ArcGIS License Manager 10.3.1, then the port information in the Service.txt file will be retained. The lmgrd daemon port is communicated to the portal as part of the exported portal configuration *.json file.
