rpld.conf(4)
NAME
rpld.conf - Remote Program Load (RPL) server configuration
file
SYNOPSIS
/etc/rpld.conf
DESCRIPTION
The /etc/rpld.conf file contains the configuration informa-
tion for operation of rpld, the RPL-based network boot
server. It is a text file containing keyword-value pairs
and comments.
The keyword-value pairs specify the value to use for param-
eters used by the RPL server. Comments can be entered by
starting the line using the # character. The user can add
comments to the file for customized configurations.
Alternate RPL server configuration files can be specified
when running the RPL server by supplying a configuration
file similar to the default configuration file.
Keywords
All keywords are case-sensitive. Not all keywords must be
present. (However, note that the end keyword at the end of
the file must be present.) If a keyword is not present,
internal defaults, which are the default values described
here, will be used. Keyword-value pairs are specified by:
keyword = value
DebugLevel
Specify the number of error, warning, and information
messages to be generated while the RPL server is run-
ning. The valid range is 0-9. A value of 0 means no
message at all, while a value of 9 will generate the
most messages. The default is 0. Note that it is best
to limit the value to 8 or below; use of level 9 may
generate so many debug messages that the performance
of the RPL server may be impacted.
DebugDest
A numeric value specifying where to send the messages
to:
0 = standard output
1 = syslogd
2 = log file
The default is 2.
MaxClients
A numeric value specifying the maximum number of
simultaneous network boot clients to be in service. A
value of -1 means unlimited except where system
resources is the limiting factor. Any positive value
will set a limit on the number of clients to be in
service at the same time unless system resource con-
straints come in before the limit. The default is -1.
BackGround
A numeric value indicating whether the RPL server
should run in the background or not. A 0 means run in
the background and a 1 means do not run in the back-
ground. The difference is whether the server will
relinquish the controlling terminal or not. The
default is 1.
FrameSize
The default size of data frames to be used to send
bootfile data to the network boot clients. This size
should not exceed the limits imposed by the underlying
physical media. For ethernet/802.3, the maximum phy-
sical frame size is 1500 octets. The default is 1500.
Note that the protocol overhead of LLC1 and RPL is 32
octets, resulting in a maximum data length of 1468
octets.
LogFile
The log file to which messages will be sent if DebugD-
est is set to 2 (the default). The default file is
var/spool/rpld.log.
StartDelay
The initial delay factor to use to control the speed
of downloading. In the default mode of operation, the
downloading process does not wait for a positive ack-
nowledgment from the client before the next data frame
is sent. In the case of a fast server and slow
client, data overrun can result and requests for
retransmission will be frequent. By using a delay
factor, the speed of data transfer is controlled to
avoid retransmission requests.
Note that the unit of delay is machine dependent and
bears no correlation with the actual time delayed.
DelayGran
Delay granularity. If the initial delay factor is not
suitable and the rate of downloading is either too
fast or too slow, retransmission requests from the
clients will be used to adjust the delay factor either
upward (to slow down the data rate) or downward (to
speed up the data rate). The delay granularity is
used as the delay delta for adjustment.
end Keyword at the end of the file. It must be present.
