Root access requirement on Unix and Linux

Super-user access is required on Unix and Linux systems for running the following:
  • sm_server - Domain Manager, handling ICMP packets, SNMP trap receiving on default port 162
  • brstart - Broker on default port 426
  • sm_trapd - SNMP trap receiving on default port 162
    A Domain Manager must bind to multiple low numbered (less than 1024) ports for listening for ICMP traffic. In addition, the default port for starting a Broker (426) and SNMP trap processing (162) are also low-numbered ports. Access to low-numbered ports requires root access on Unix and Linux systems.
    You can also start a Domain Manager with root access and then open additional ports as a non-root user, if this is required.
