DESCRIPTION

Rmtcfgd is a server program used to send configuration files to a Gracilis PackeTen. It
can be run in background or it can be run by inetd. If p10cfgd is to be run by inetd, add
the following line to /etc/services

rmtcfg 1236/tcp # Remote Configuration of PackeTen

and add the following to /etc/inetd.conf

# Remote configuration service for PackeTen
rmtcfg stream tcp nowait root /usr/bin/p10cfgd p10cfgd

P10cfgd normally does not require the IP_PORT parameter. It listens for connections on IP
Port 1236 as a default.

The program will send on a line by line basis the file requested by the client that
connects on the IP Port. The only expected input from the client is the file name. When
the file has been sent, the connection is closed. The requested file must be in the
directory /etc/p10cfgd.

Rmtcfgd maintains a log of its activity in the file /var/log/p10cfgd.log. Program startup
and all connections are logged in the file with GMT time stamps. The file is opened in
append mode.

The protocol used by the PackeTen is very simple. The PackeTen opens a tcp connection to
port 1236 on a host system. Once the connection is made, the PackeTen sends the name of
the file it wants to the host. The host then opens the file and sends it line by line to
the PackeTen until all lines have been sent. The files to be transfered must be plain
text files and each line must have at least one character in addition to the newline at
the end. P10cfgd replaces all blank lines with lines that contain two spaces. If you
wish to send a blank line, to stop loading of part of a LocalInfo file for example, place
an underscore '_' at the begining of the line. The entire contents of the line will be
deleted and a blank line will be sent to the client. At the end of the file, the server
sends a time command ( time MMDDYYHHMM ) with the UTC time on the server. This will
either set the time on the PackeTen or add a time stamp to the LocalInfo file. The server
then closes the connection.

The remote configuration command used on the PackeTen is
rmtcfg <server_host> <filename> [options]
The valid options are
-t <timeout in seconds> default is 60 sec
-p <IP port #> default is 1236
-i the file is for LocalInfo
-h <secondary server> if the primary does not answer

The rmtcfg commands would be placed in to the EEPROM on the PackeTen so that they would
be executed during a reboot. The information stored in the EEPROM should include enough
information to set the PackeTen up to allow communications with the primary and the
secondary server. This would include commands to set MYCALL and the IP_ADDRESS, to attach
an interface to the channel with the server, routing information and so forth. A sample
EEPROM configuration for a PackeTen, empire.wd0fhg.ampr.org [44.32.0.32], that gets its
configuration from a remote system winfree.n3eua.ampr.org [44.32.0.2], over a 9600 baud
ax25 path would be:

# first the general setup of the PackeTen
ee hostname gw.wd0fhg
ee sitename empire
ee ipaddr 44.32.0.32
ee mycall WD0FHG
# Then we attach a 9600 ax25 interface as ax1
ee attach sync302 1 hdx ax25 ax1 8192 256 9600 ext ext nrzi
# and set the default route to send every thing out ax1
ee route add default ax1 44.32.0.1
ee password sure-thing
#
# Now we will ask for the remainder of the setup
# from the server winfree.n3eua.ampr.org [44.32.0.2]
# Note that we have a secondary server available at
# [44.20.0.195] that would be used if winfree is down.
# first the Local Information file
ee com 0 rmtcfg 44.32.0.2 empire.info -i -h 44.20.0.195
# and then the remaining configuration command file
ee com 1 rmtcfg 44.32.0.2 empire.cfg -h 44.20.0.195
#
ee save
# end-of-eeprom setup
