Last update: Sun Mar 13 15:05:31 PST 1994This file hopefully describes the whatever and however of how to get xntprunning on hpux 7.0 and later s300. s400, s700, and s800.  First off,  all the standard disclaimers hold here ... HP doesn't have anthingto do with this stuff.  I fool with it in my spare time because we use it andbecause I like to.  We just happen to have a lot of HP machines around here :-)Xntpd has been in use here for several years and has a fair amount of mileageon various HP platforms within the company.  I can't really guarantee bug fixesbut I'd certainly like to hear about bugs and I won't hestitate to look atany fixes sent to me.  Now lets talk OS.  If you don't have 7.0 or later, pretty much hang it up now.This stuff has run here on pretty much everything from 8.0 upward on s300, s700, and s800.  It is known to run on 7.0 s300/s400 but all reports are from the field and not my personal experience.If you are lucky enough to have a s300 or s400 with 9.03, then you no longerhave to worry about adjtimed as HP-UX now has adjtime(2).  The rest of youwill have to wait on 10.0 which will have adjtime(2) and a supported thougha bit older version of xntpd.Next, let me explain a bit about how this stuff works on HP-UX's that do nothave adjtime(2).  The directory adjtime contains libadjtime.a and the adjtimeddaemon.  Instead of the adjtime(2) system call, we use a library routine totalk to adjtimed thru message queues.  Adjtimed munges into /dev/kmem andcauses the clock to skew properly as needed.  PLEASE NOTE that the adjtimecode provided here is NOT a general replacement for adjtime(2) ... use ofthis adjtime(3)/adjtimed(8) other than with xntpd may yield very odd results.What to do to get this stuff running ?    * If you are running an OS less than 10.0 or do not have a s300/s400       with 9.03 or better	-> cd machines	-> vi hpux	-> (change -DSYS_HPUX=? to match whatever you are running [7,8,9])	-> cd ..    * Say "make makeconfig"    * Say "make", sit back for a few minutes.    * cd authstuff	* Say "./authcert < certdata" and check the output.  Every line should	  end with "OK" ... if not, we got trouble.	* Now try "./authspeed auth.samplekeys".  What we want to 	  remember here is the "authentication delay in CPU time" 	* cd ..    * Say "make install"    * I'd suggest reading the xntp docs about now :-) ... seriously !!    * One thing I have added to this version of xntpd is a way to select       config files if you are sharing /usr/local thru NFS or whatever.        If the file /usr/local/etc/xntp.conf happens to be a directory, the       files in that directory are searched until a match is found.  The       rules for a match are:	1. Our hostname	2. default.<machine id> (as in default.375 or default.850)	3. default    * Ok, make sure adjtimed is running (just start it up for now with      "/usr/local/etc/adjtimed").  Using -z as an option will get you       a usage message.    * Now start up xntpd and watch it work.    * Make sure that adjtimed gets started at boot right before xntpd.      We do this in /etc/netbsdsrc.  They must both run as root !!Possible problems ?    * On some 320's and 835's we have had to run adjtimed with "-p 45" or      so to get rid of syslog messages about "last adjust did not finish".    * At 9.0, there is a problem with DIAGMON (patch available from the      response center) which causes it to delete the message queue that      adjtimed/xntpd use to communicate. (see next note for result)    * Xntpd has been known to get really ticked off when adjtime() fails      which is usually only while running the emulation code on HP-UX.      When it gets mad, it usually jumps the clock into never never land.      Possible reasons for this are adjtimed being killed or just never      started or adjtimed being completely swapped out on a really busy      machine (newer adjtimed try to lock themselves in memory to prevent      this one).Anything else ... just drop me a line at ken@sdd.hp.comReceived: from louie.udel.edu by huey.udel.edu id aa14418; 15 Jun 95 9:19 EDTReceived: from host5.colby.edu (host-05.colby.edu) by host-04.colby.edu with ESMTP  (1.37.109.15/Colby 1.1)	id AA165442355; Thu, 15 Jun 1995 09:19:16 -0400Received: by host5.colby.edu  (1.37.109.15/Colby 1.1)	id AA056252339; Thu, 15 Jun 1995 09:18:59 -0400Date: Thu, 15 Jun 1995 09:18:59 -0400 (EDT)From: "Jeff A.

In the course of doing this, I discovered that:--> $(TOP) is not defined in adjtime/Makefile, so "make install" can't    find the install.sh script.--> "make install" from the main Makefile never goes into the adjtime    directory, so I added the following two lines into the install    target of the main Makefile:    @echo installing from adjtime    @cd adjtime && $(MAKE) $(MFLAGS) MFLAGS="$(MFLAGS)" MAKE="$(MAKE)" installThis twiddle may not be right for all systems, but it got adjtimedinstalled for me.   You might also want to add to the hpux hints file that one way tofire things up at boot time is to add the following lines to the localrcfunction of /etc/rc:    #---daemons for Network Time Protocol (version 3.4s)    #---note that adjtimed is only needed for HP-UX 9.X, not 10.0    #---adjtimed must be running or xntpd won't work right...    if [ -x /usr/local/bin/adjtimed ]; then        /usr/local/bin/adjtimed -r & echo -n ' adjtimed'        if [ -x /usr/local/bin/xntpd ]; then            /usr/local/bin/xntpd &    echo -n ' xntpd'        fi    fiI discovered that the "-r" option of adjtimed is needed to clear out anytrash from a previous execution of it.  Otherwise adjtimed quietly diesand leaves xntpd in the lurch...Thanks for the help.** Jeff A.
