Change Configurable Port Numbers
If it is necessary to change one or more of the network port numbers used
by Matrix Server, simply add the service line or lines that you want to
change to the /etc/services file on all nodes in the matrix. (See the next
section for the format of the entries.) After editing the file, either reboot
each node or stop and restart Matrix Server on all nodes.
Matrix Server Entries in the /etc/services File
The reconfigurable network port numbers available for Matrix Server are
as follows. If a line shown below does not exist in the /etc/services file, the
default port will be chosen. If you need to reconfigure a port number, add
the appropriate line to the file and then modify the number. Port numbers
can be changed but names and transport types (tcp, udp) cannot.
