The SPD Server listen
and operator ports can be specified using well-known port definitions
that are declared in the operating system's services file, or they
can be specified using the SPD Server command line interface. In the
operating system's services file, the
spdsserv_sas specification corresponds to the SPD Server listen port. The
spdsserv_oper specification corresponds to the SPD Server
operator port. The SPD Server listen and operator ports can also be
defined in the
rc.spds start-up script for
UNIX installations. In a
rc.spds start-up
script, the
SRVLPORT parameter defines the
listen port, and the
SRVOPORT parameter defines
the operator port. If the listen and operator ports are not defined,
or are defined as a zero value, the SPD Server will by default use
spdsserv_sas and
spdsserv_oper in the operating system's services file. If there are no listen
or operator ports defined in the operating system's services file,
then SPD Server will choose any available ports for listen and operator
port functions. This is the normal mode of operation when SPD Server
clients and servers run in environments that have no firewalls.
