11.2 Portmapper Startup and Shutdown
The Portmapper service can be shut down and started independently. This is
useful when you change parameters or logical names that require the service to
be restarted.
The following files are provided:
• SYS$STARTUP:TCPIP$PORTMAPPER_STARTUP.COM allows you start up
the Portmapper service separately.
• SYS$STARTUP:TCPIP$PORTMAPPER_SHUTDOWN.COM allows you to
shut down the Portmapper service separately.
To preserve site-specific parameter settings and commands, you can create
the following files. These files are not overwritten when you reinstall TCP/IP
Services:
• SYS$STARTUP:TCPIP$PORTMAPPER_SYSTARTUP.COM can be used as a
repository for site-specific definitions and parameters used in the Portmapper
startup procedure.
• SYS$STARTUP:TCPIP$PORTMAPPER_SYSHUTDOWN.COM can be used
as a repository for site-specific definitions and parameters used in the
Portmapper shutdown procedure.
11.3 Displaying Portmapper Information
The following examples show a variety of commands you can use to get
information about the Portmapper and the services that depend on it.
1. The following example displays the RPC options for these running services:
MOUNT, NFS, PC-NFS, and the Portmapper.
TCPIP> SHOW SERVICE /RPC /PERMANENT
RPC Protocol Versions
Service Program Number Lowest / Highest
MOUNT 100005 1 3
NFS 100003 2 3
PCNFS 150001 1 2
PORTMAPPER 100000 2 2
TCPIP>
2. In the following example, the /FULL and /PERMANENT qualifiers display
the RPC options for the NFS server, whose program number is 100003, lowest
version is 2, and highest version is 3.
TCPIP> SHOW SERVICE NFS /FULL /PERMANENT
Service: NFS
Port: 2049 Protocol: UDP Address: 0.0.0.0
Inactivity: 0 User_name: TCPIP$NFS Process: TCPIP$NFS
