TCP/IP based

Communication between CodeMeter WebAdmin and connected CmContainer is browser-based and uses network components. Thus the installation of the network protocol TCP/IP is required, and access must be granted to the localhost.

However, an actual connection to the Internet is not established.

Network Server and Server Access

By default, CodeMeter License Server is only available locally (localhost).

information_weiss_klein26

A change of the remote access to CodeMeter WebAdmin during operation requires a restart of the CmWebAdmin service. Please note the firewall settings.

Firewall Settings

Please also note that the settings of your firewall do not block communication.

information_weiss_klein26

CodeMeter License Server uses a specific IP port (defaulted on 22350) to communicate with your PC and the network. This network port is registered at IANA (Internet Assigned Numbers Authority) and uniquely assigned for CodeMeter communication.

Make sure that your firewall is not blocking this port. Enable the used IP port 22350 and make sure it is accessible by CodeMeter, i.e. share the communication for this IP port.

If the CodeMeter WebAdmin communication is required not only locally but also in server operation, you must also release port 22352 (in the case of HTTPS, port 22353), since port 22350 is automatically forwarded.

Communication Mode

By editing registry or server entries you are also able to define which communication mode CodeMeter License Server uses.

The following table shows you where for which operating system you find the profiling to set the communication mode.

Operating system

Registry / Server Entry

Windows

HKLM/SOFTWARE/WIBU-SYSTEMS/CodeMeter/Server/CurrentVersion

macOS

/Library/Preferences/com.wibu.CodeMeter.Server.ini

Linux

/etc/wibu/CodeMeter/Server.ini

The parameter ApiCommunicationMode. is available for setting the mode. The following properties are available:

CodeMeter-Version

smaller than 4.40

'1'  TCP/IP (Default)

'2'  Shared Memory

starting with 4.40

'1'  Platform-specific (Default)

Platform-specific defaults:

Windows: IPv6, IPv4; Shared Memory

Linux/macOS:IPv6, IPv4

WinCE: IPv4, Shared Memory

'2'  Shared Memory

'4'  IPv4

'8'  IPv6

Single modi may be combined.
