Included in this distribution of XNTP is a configuration file suitable for use with BSDI’s BSD/OS 1.1 (formerly BSD/386 1.1). On this system, the cc command is GCC 1.4x rather than PCC or GCC 2.x. It is imperative that cc be used since it predefines the symbol _bsdi_; if you want to use another compiler you will need to add -D_bsdi_ to catch the various #ifdef’s required for this system.

The Kinemetrics/Truetime GPS-TM/TMD driver is known to work on this system. The GPS-805 and GOES should also work fine. Hell, they should all work fine but it’s hard to test very many locally.

Due to BNR2’s strict interpretation of POSIX and XNTP’s use of SIGIO, BSD/OS can only handle one refclock per daemon. We’re working this out with the system architects.

The config file is machine/bsdi, and the following steps should be all that are required to install and use the bits.

Note that you will need GNU sed; the version supplied with BSD/OS 1.1 loops endlessly during make refconf. Likewise you should get GNU make, which the instructions below assume that you have put in /usr/local/bin/gnumake.

To build the software:

rm -f Config.local
gnumake refconf
gnumake MAKE=gnumake

To install the software:

gnumake install

This will place all of the executables in /usr/local/etc. The config file is expected to be /usr/local/etc/xntp.conf and the key file for the optional authentication is /etc/ntp.keys.

Craft a config file and a key file, and put them in the right places. There is information on how to do this elsewhere in the documentation, the only thing I’ll mention is that I put the drift file in /var/log/ntp.drift, and the authdelay on my 486DX/50 system is 0.000064. Your mileage will vary, learn to use the authspeed tools if you’re going to authenticate.

In the file /etc/rc.local, make sure that the invocation of ntpd is commented out, and add an invocation of xntpd. Here’s what I’m using:

    echo -n 'starting local daemons:'

	if [ -f /etc/ntp.keys -a -f /usr/local/etc/xntp.conf ]; then
        echo -n ' xntpd';           /usr/local/etc/xntpd
	fi

	#XXX# echo -n ' ntpd';          /usr/libexec/ntpd -t

At this point, you should be good to go. Try running /usr/local/etc/xntpd and using ntpq or xntpdc to see if things are working, then pay attention the next time you reboot to make sure that xntpd is being invoked, and use ntpq or xntpdc again to make sure all is well.

Enjoy!
