Sometimes when starting the Spectrum applications on Linux, they are not able to start because the ports they bind to are already being used by another process.
To reserve the tcp ports that Spectrum uses, the following can be added to the /etc/sysctl.conf file:
After adding the above, run the following command:
NOTE: You must be the root user or have sudo root privileges
NOTE: The Spectrum 10.3 installation updates the /etc/sysctl.conf file with the Spectrum ports.
For a complete list of ports used by Spectrum processes, please reference the "Default Port Configurations" section of the documentation.
