+.SH NAME
+p10cfgd \- remote configuration daemom for Gracilis PackeTen
+.SH SYNOPSIS
+.B p10cfgd [IP_PORT]
+.SH COPYRIGHT
+Copyright (c) 1993 by Colorado Digital Eclectics (CODE)
+
+All rights reserved.
+
+.SH DESCRIPTION
+.I 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
+.I p10cfgd
+is to be run by inetd, add the following line to
+.I /etc/services
+
+.nf
+rmtcfg 1236/tcp # Remote Configuration of PackeTen
+.fi
+
+and add the following to
+.I /etc/inetd.conf
+
+.nf
+# Remote configuration service for PackeTen
+rmtcfg stream tcp nowait root /usr/bin/p10cfgd p10cfgd
+.fi
+
+.I 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.
+
+.I 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.
+.I 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
+.nf
+ 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
+.fi
+
+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:
+
+.nf
+ # 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
