NAME
sysconfig - configure DG/UX tunable parameters
SYNOPSIS
sysconfig -o set -g group [ parameter=value ... ]
sysconfig -o get -g group [ -qv ] all | parameter ...
sysconfig -o help -g group [ -qv ] all | parameter ...
sysconfig -o reset -g group all | parameter ...
DESCRIPTION
Sysconfig provides a mechanism for configuring and retrieving the
DG/UX tunable parameters that appear in DG/UX 5.4 Release 3.00 and
later versions of the DG/UX operating system. These tunable
parameters are:
ipttl IP Time-to-Live is the maximum hop count an IP packet may
travel before being dropped. This value may range from 1
to 255 hops. The default is 255.
ipforwarding
IP Forwarding is a switch to permit the forwarding of IP
packets through the local machine so that the local machine
acts as a gateway. This value may either be on or off.
The default is on. Note: This value does not affect
source-routed IP packets.
ipsrcrtforward
IP Non-Local Source Route Forwarding is a switch to prevent
the forwarding of IP source-routed packets through an
interface and out a different interface on the local
machine. This value may either be on or off. The default
is off.
tcpkeepalive
TCP Default Keep-Alive Idle Time is the number of seconds
TCP will wait before sending Keep-Alive probes provided the
Keep-Alive facility is active. The value may range from 0
to 14400 seconds. The default is 7200.
arptimeout
Base ARP Cache Time-out is the number of seconds used as
the base value for determining ARP cache time-outs.
Complete ARP entries multiply this value by 20 to get their
actual timeout while incomplete entries multiply the value
by 3. The values for arptimeout may range from 1 to
100000 seconds. The default is 60.
Operations
set Set the value of one or more tunable parameters within a
given parameter group.

sysconfig(1M) DG/UX 5.4R3.00 sysconfig(1M)
get Get the value of one or more tunable parameters within a
given parameter group.
help List the names of all DG/UX tunable parameters configurable
by sysconfig(1M) and their descriptions for a given
parameter group.
reset Reset one or more of the tunable parameters within a
parameter group to its system default value.
Options
-g "Group." The name of the group of DG/UX tunable parameters
to be operated upon. Currently the only group supported is
tcpip.
-q "Quiet." Produce an unformatted listing (i.e. no headers,
fields delimited by a single space) and suppress
acknowledgement messages.
-v "Verbose." Produce a formatted listing with headers and
aligned columns. This option is enabled by default.
EXAMPLES
In the following examples, the system administrator performs the
following actions: set ipttl to 10 and ipforwarding to off; get the
values for arptimeout and for tcpkeepalive; get the values of all
tunable parameters within group tcpip without displaying header
information and get a list of all tunable parameters within the group
tcpip with descriptions and value ranges.
sysconfig -o set -g tcpip ipttl=10 ipforwarding=off
sysconfig -o get -g tcpip arptimeout tcpkeepalive
sysconfig -o get -g tcpip -q all
sysconfig -o help -g tcpip all
OUTPUT
The get and help operations write their output to stdout. The set
and reset operations write their acknowledgment messages to stdout as
well.
The verbose form of the get and help operations output information in
aligned columns with column headers.
The quiet form of these operations suppresses headers, and the quiet
form of the help operation suppresses the description fields as well.
DIAGNOSTICS
The following error messages do not immediately abort the operation.
If the user tries to get or set more than one parameter, sysconfig
will attempt to perform the operation on all of the specified
parameters. It will give an error message for each parameter where
the operation fails.
