To make the executables follow -the steps outlined below. - -*** NOTE: You must have gcc installed to successfully compile the current -distribution; the native cc supplied with A/UX will NOT correctly compile -this source. See the FAQ in comp.unix.aux for places to obtain gcc from -and how to install it. - -Now, you need to create the makefiles: - - % make refconf - -First of all, you need to edit Config.local to make sure that BINDIR is -correct for where you wish the programs to be "installed". The default -(and what I use) is /usr/local/etc. Make sure that DEFS_LOCAL and -CLOCKDEFS are commented out! - - -After this is done (you should be told that your system is A/UX 3), make -xntpd (the options to 'gcc' are held in compilers/aux3.gcc): - - % make - -I do not normally use the `make install' option and so have not verified its -compatibility with A/UX. Rather, I pull out each of the executables and -place them in the locally appropriate locations. - -At this point you need to set things up so that 'xntpd' is started upon -boot-up. You can do this in 1 of 2 ways: either add entries in /etc/inittab -or create and use an /etc/rc.local file. - -By default, A/UX doesn't have one, so you'll need to add the following to -/etc/inittab: - - net6:2:wait:/etc/syslogd # set to "wait" to run a syslog daemon -+ jmj0:2:wait:/etc/rc.local 1>/dev/syscon 2>&1 # Local stuff - dbg2::wait:/etc/telinit v # turn off init's verbose mode - -Now, the look of /etc/rc.local is as follows: - - #!/bin/sh - : - : rc.local - : - # @(#)Copyright Apple Computer 1987 Version 1.17 of rc.sh on 91/11/08 15:56:21 (ATT 1.12) - - - # Push line discipline/set the device so it will print - /etc/line_sane 1 - echo " " - echo "Entering rc.local..." - - set `/bin/who -r` - if [ "$7" = 2 ] - then - /bin/echo " now setting the time..." - /usr/local/etc/ntpdate -s -b <host.domain> - sleep 5 - # - # start up xntpd if we want - # - if [ -f /etc/ntp.conf ] - then - /bin/echo " setting tick and tickadj..." - /usr/local/etc/tickadj -t 16672 -a 54 - sleep 5 - /bin/echo " starting xntpd..." - /usr/local/etc/xntpd <&- > /dev/null 2>&1 - sleep 5 - fi - # - fi - - echo "Leaving rc.local..." - -There are a few things to notice about the above: - - o When run, 'ntpdate' forces your clock to the time returned by the - host(s) specified by <host.domain> (you'll need to replace this - be the IP address(es) of your timehosts. This is good since it gets - things close to start off with. - - o 'tickadj' is also called. This does two things: changes the - default value of 'tick' (which the the amount of time, in ms, that - is added to the clock every 1/60 seconds) and changes the value - of 'tickadj' which the the amount that is added or subtracted - from 'tickadj' when adjtime() is called. - - Now Mac clocks are pretty bad and tend to be slow. Sooo, instead of - having A/UX add the default of 16666ms every 1/60th of a second, - you want it to add more so that it keeps better time. The above - value works for me but your "best" value may be different and will - likely require some fooling around to find the best value. - - A/UX's default value of 'tickadj' is 1666 which is too big for - 'xntpd'... so it also needs to be adjusted. - - -Finally, before A/UX and 'xntpd' will work happily together, you need to -patch the kernel. This is due to the fact that A/UX attempts to keep the -UNIX-software clock and the Mac-hardware clock in sync. Now both of these -are too good. Also, 'xntpd' will be attempting to adjust the software -clock as well, so having A/UX muck around with it is asking for headaches. -What you therefore need to do is tell the kernel _not_ to sync the s/w clock -with the h/w one. This is done using 'adb'. The following is a shell script -that will do the patch for you: - - #! /bin/sh - adb -w /unix <<! - init_time_fix_timeout?4i - init_time_fix_timeout?w 0x4e75 - init_time_fix_timeout?4i - $q - ! - -This must be done _every_ time you create a new kernel (via newconfig or -newunix) or else 'xntpd' will go crazy. - -John Dundas was the original porter of xntpd and a lot of the additions -and A/UX-ports are from him. I got involved when I wanted to run 'xntpd' -on jagubox. It was also around this time that the base-patchlevel of -'xntpd' changed relatively significantly so John may not be up on this -version (called the "jones" version). - -The original kernel patch (which patched 'time_fix_timeout') was from -Richard Todd. I suggest patching 'init_time_fix_timeout' which prevents -'time_fix_timeout' from even being called. - -TECHNICAL NOTES: - - o As configured (see machines/aux3), 'xntpd' will log messages via syslogd - using the LOC_LOCAL1 facility. I would suggest the following in - /etc/syslog.conf: - - local1.notice /usr/adm/ntpd-syslog - - o As mentioned above, the clocks on A/UX and Macs are kinda bad. Not - only that, but logging in and out of the MacOS mode as well as - extensive floppy use causes A/UX to drop and lose clock interupts - (these are sent every 1/60th of a second). So, if you do these - activities a lot, you find out that you lose about 300ms of time - (i.e., you become 300ms slow). 'xntpd' default way of handling this - is to called 'settimeofday()' and step the clock to the correct - time. I prefer having 'xntpd' slew the clock back into line by - making gradual adjustments to the clock over a coupla minutes - or so. It's for this reason that SLEWALWAYS is defined in - include/ntp_machine.h for SYS_AUX3. - -Good luck! If you have problems under A/UX feel free to contact me (e-mail -is preferred). --- - Jim Jagielski | "That is no ordinary rabbit...
