Summary

Synopsis

When trying to start the license server, the debug log reports the following and then terminates.
"(lmgrd) Failed to open any default TCP port."

Discussion

This error is normally a OS network configuration setting.
The reason this type of error is due to a machine setting is because FLEXlm/FLEXnetPublisher passes TCP/IP communication requests directly to the OS TCP/IP kernel, and depends on that system (with user defined DNS/NIS/WINS and SSL/TLS network configuration) to handle all communications processing (with any associated socket/layer related security protocols). FLEXlm/FLEXnetPublisher relies entirely on the OS TCP/IP-SSL/TLS configuration(s) to handle the system-network level communication connections.
As a test, try and ping other machines on the network as well as the localhost using both the IP and hostnames. This will normally confirm a problem.
One possible resolution for this is to configure your /etc/nsswitch.conf file correctly.
