1.2 Isolating Problems
& This column lists whether the service is enabled or disabled. The term
enabled indicates that the next time TCP/IP Services starts, TCP/IP Services
starts all services that are marked in the service database as enabled. In this
example, of the services listed, all services except
finger
will start the next
time TCP/IP Services restarts.
Note
In this example, the
finger
service was configured with TCPIP$CONFIG.
However, at some point,
finger
was disabled either by a TCPIP
management command or by an incremental shutdown of the service.
1.2.10.2 Displaying Service Attributes
Each service should have the following items defined in the services database:
• OpenVMS user account (also in user authorization file [UAF])
• Unique port number
• Protocol
• Name and location of the startup command procedure and log file
• Service parameters (for example, timeouts, privileges)
• Flags
If these items are not defined correctly, or if the service account privileges and
file protections are not assigned correctly, the service will fail to respond to an
incoming request. This failure may be logged in the service-specific log file.
To display information about a service, enter the TCPIP command SHOW
SERVICE /FULL and specify the service name. For example:
$ TCPIP
TCPIP> SHOW SERVICE /FULL TELNET
Service: TELNET

name, user name, port and interface on which the service is listening,
whether the service is enabled or disabled, and the number of copies of
the service that can run at one time.
