DESCRIPTION

pmadm is the administrative command for the lower level of the Service
Access Facility hierarchy, that is, for service administration. A port
may have only one service associated with it although the same service
may be available through more than one port. In order to uniquely
identify an instance of a service, the pmadm command must identify both
the port monitor or port monitors through which the service is available
(-p or -t) and the service (-s). See .


pmadm performs the following functions:

o adds or removes a service

o enables or disables a service

o installs or replaces a per-service configuration script

o prints requested service information


Any user on the system may invoke pmadm to request service status (-l or
-L) or to print per-service configuration scripts (-g without the -z
option). pmadm with other options may be executed only by a privileged
user.

OPTIONS

The following options are supported:

-a
Add a service. pmadm adds an entry for the new service
to the port monitor's administrative file. Because of
the complexity of the options and arguments that follow
the -a option, it may be convenient to use a command
script or the menu system to add services.


-d
Disable a service. Add x to the flag field in the entry
for the service svctag in the port monitor's
administrative file. This is the entry used by port
monitor pmtag. See the -f option, below, for a
description of the flags available.


-e
Enable a service. Remove x from the flag field in the
entry for the service svctag in the port monitor
administrative file. This is the entry used by port
monitor pmtag. See the -f option, below, for a
description of the flags available.


-f xu
The -f option specifies one or both of the following two
flags which are then included in the flag field of the
entry for the new service in the port monitor's
administrative file. If the -f option is not included,
no flags are set and the default conditions prevail. By
default, a new service is enabled and no utmpx entry is
created for it. An -f option without a following
argument is illegal.

x
Do not enable the service svctag available through
port monitor pmtag.


u
Create a utmpx entry for service svctag available
through port monitor pmtag.


-g
Print, install, or replace a per-service configuration
script. The -g option with a -p option and a -s option
prints the per-service configuration script for service
svctag available through port monitor pmtag. The -g
option with a -p option, a -s option, and a -z option
installs the per-service configuration script contained
in the file script as the per-service configuration
script for service svctag available through port monitor
pmtag. The -g option with a - s option, a -t option, and
a -z option installs the file script as the per-service
configuration script for service svctag available
through any port monitor of type type. Other
combinations of options with -g are invalid.


-i id
id is the identity that is to be assigned to service
svctag when it is started. id must be an entry in
/etc/passwd.


-l
The -l option requests service information. Used by
itself and with the options described below, it provides
a filter for extracting information in several different
groupings.

-l
By itself, the -l option lists
all services on the system.


-l -p pmtag
Lists all services available
through port monitor pmtag.


-l -s svctag
Lists all services with tag
svctag.


-l -p pmtag-ssvctag
Lists service svctag.


-l -t type
Lists all services available
through port monitors of type
type.


-l -t type-ssvctag
Lists all services with tag
svctag available through a port
monitor of type type.

Other combinations of options with -l are invalid.


-L
The -L option is identical to the -l option except that
output is printed in a condensed format.


-m pmspecific
pmspecific is the port monitor-specific portion of the
port monitor administrative file entry for the service.


-p pmtag
Specifies the tag associated with the port monitor
through which a service (specified as -s svctag) is
available.


-r
Remove a service. When pmadm removes a service, the
entry for the service is removed from the port monitor's
administrative file.


-s svctag
Specifies the service tag associated with a given
service. The service tag is assigned by the system
administrator and is part of the entry for the service
in the port monitor's administrative file.


-t type
Specifies the port monitor type.


-v ver
Specifies the version number of the port monitor
administrative file. The version number may be given as

-v 'pmspec -V


where pmspec is the special administrative command for
port monitor pmtag. This special command is ttyadm for
ttymon and nlsadmin for listen. The version stamp of the
port monitor is known by the command and is returned
when pmspec is invoked with a -V option.


-y comment
Associate comment with the service entry in the port
monitor administrative file.


-z script
Used with the -g option to specify the name of the file
that contains the per-service configuration script.
Modifying a configuration script is a three-step
procedure. First a copy of the existing script is made
(-g alone). Then the copy is edited. Finally, the copy
is put in place over the existing script (-g with -z).


Options that request information write the requested information to the
standard output. A request for information using the -l option prints
column headers and aligns the information under the appropriate headings.
In this format, a missing field is indicated by a hyphen. A request for
information in the condensed format using the -L option prints the
information in colon-separated fields; missing fields are indicated by
two successive colons. # is the comment character.

EXAMPLES

Example 1: Adding a Service to a Port Monitor with the Tag pmtag

The following command adds a service to a port monitor with tag pmtag and
gives the service the tag svctag. The port monitor-specific information
is generated by specpm. The service defined by svctag will be invoked
with identity root.


pmadm -a -p pmtag -s svctag -i root -m `specpm -a arg1 -b arg2`-v `specpm -V`

Example 2: Adding a Service with Service Tab svctag

The following command adds a service with service tag svctag, identity
guest, and port monitor-specific information generated by specpm to all
port monitors of type type:


pmadm -a -s svctag -i guest -t type -m `specpm -a arg1 -b arg2`-v `specpm -V`

Example 3: Removing a Service

The following command removes the service svctag from port monitor pmtag:


pmadm -r -p pmtag -s svctag

Example 4: Enabling a Service

The following command enables the service svctag available through port
monitor pmtag:


pmadm -e -p pmtag -s svctag

Example 5: Disabling a Service

The following command disables the service svctag available through port
monitor pmtag:


pmadm -d -p pmtag -s svctag

Example 6: Listing Status Information

The following command lists status information for all services:


pmadm -l

Example 7: Listing Status Information

The following command lists status information for all services available
through the port monitor with tag ports:


pmadm -l -p ports

Example 8: Listing Status Information in Condensed Format

The following command lists the status information for all services
available through the port monitor with tag ports in condensed format:


pmadm -L -p ports

Example 9: Listing Status Information for All Services

List status information for all services available through port monitors
of type listen:


pmadm -l -t listen

Example 10: Printing the per-service Configuration

The following command prints the per-service configuration script
associated with the service svctag available through port monitor pmtag:


pmadm -g -p pmtag -s svctag

EXIT STATUS

The following exit values are returned:

0
Successful operation.
