Introduction:
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. 

 
Environment:
Spectrum 10.2.3 and older on Linux
Instructions:
To reserve the tcp ports that Spectrum uses, the following can be added to the /etc/sysctl.conf file:

net.ipv4.ip_local_reserved_ports=7777,14002,14003,14004,14006,14012,14013,14014,14016,46517,47870,48879,51966,56063,61904,64222,65259

After adding the above, run the following command:

sysctl -p

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.
Additional Information:
For a complete list of ports used by Spectrum processes, please reference the "Default Port Configurations" section of the documentation located at https://docops.ca.com/ca-spectrum/10-2-3/en/administrating/distributed-spectroserver-administration/communication-across-firewalls/default-port-configurations
