.SH NAME
drpadmin - Digi Realport Configuration Utility
.SH SYNOPSIS
.TP 14
drpadmin
.SH DESCRIPTION
The drpadmin utility is invoked by the system administrator to
view, add, remove, or change the configuration of RealPort-enabled
Products used with the
.B dgrp
driver. When invoked by a non root user the current configuration
is displayed along with any kernel warning messages. Configuration
is not available to a non root user.
.PP
When invoked, drpadmin begins a question-and-answer
terminal conversation with the user. The user may
.B add
a RealPort-enabled product,
.B show
the current configuration and other details provided by the kernel driver,
.B remove
a previously configured unit, or
.B reset
a previously configured unit
.PP
In the
.B show
operation, the program simply displays the contents of the
.I /etc/dgrp.backing.store
file with the
.B less
program.
.PP
The show operations are safe to run any time.
The remaining operations may cause
temporary or permanent service interruptions to your Realport devices.
.PP
In the
.B add
operation, the user is asked for:
.TP 8
Remote node name or IP address
The TCP/IP node name, or the numeric dot-address of the Digi ethernet-based
serial device.
.TP
Number of ports
The number of tty devices to be created for this unit.
If this number is less than the number of physical ports,
only the entered number will be available to the Realport Driver.
The unassigned ports will be available for other connection types.
Some Digi products and drivers accept other connection types to assigned ports
so long as there are no active Realport connections.
If this number is greater, the additional devices will not be usable
unless/until the hardware is expanded.
.TP
Realport tty device id
This one or two character alphanumeric string is used to generate
the
.BI /dev/tty XN,
.BI /dev/pr XN
and
.BI /dev/cu XN
device names for this unit.
Here
.I X
is the entered string, and
.I N
is the automatically generated 2 digit port number in the range 01 to 64.
.TP
Encryption
The encryption setting for this unit. If your device does not support
encryption then encryption should not be enabled or the device will
not function. Check your device specifications to see if encryption
is supported.
.TP
Network link speed
This parameter should be specified only when the network connection from
the system to the remote device includes a WAN link slower
than 1 MBit/second.
The user may enter either simply the WAN speed
(eg 56000 for a 56K Frame Relay link)
or may enter a complete WAN speed string as documented
in the
.BR drpd (1m)
manual page.
.PP
When all data is entered, the
.B add
command calls
.B dgrp_cfg_node init
to load the kernel module if not already loaded and
activate the device. The new device is then immediately available.
.PP
drpadmin only configures the most
common options. Please see the
.BR dgrp_cfg_node (1m)
manual page for all available options.
.PP
In the
.B remove
operation, the user is first asked for the unit ID
to delete as displayed by the
.B show
option. The command then calls
.B dgrp_cfg_node uninit
to deactivate the device with the kernel module.
When the last device is deactivated the kernel module is unloaded
.PP
The configuration changes take effect immediately.
.PP
In the
.B reset
operation, the user is first asked for the unit ID
to reset as displayed by the
.B show
option. The command then calls
.B dgrp_cfg_node stop
then
.B dgrp_cfg_node start
to reset the device with the kernel module.
.PP
When the
.B reset
operation is complete all connections using the device will be reset.
.PP
To change the configuration of a remote device,
the unit must first be removed and then added back
into the configuration.
.PP
.B dgrp_cfg_node stop
and
.B dgrp_cfg_node start
can be used to change the IP address of a configured unit.
