The TCP Port Number

The TCP port number on which the xfs server daemon listens is normally the “fs” port (typically defined as 7100 in the /etc/services file). However, the -port option on the xfs command line enables the system administrator to override the default setting. You can use the Port_list property in the SUNW.xfnts resource type to set the default value and to support the use of the -port option on the xfs command line. You define the default value of this property as 7100/tcp in the RTR file. In the SUNW.xfnts Start method, you pass Port_list to the -port option on the xfs command line. Consequently, a user of this resource type isn't required to specify a port number—the port defaults to 7100/tcp—but does have the option of specifying a different port if they wish when configuring the resource type, by specifying a different value for the Port_list property.
