  3This file hopefully describes the whatever and however of how to get xntp
  4running on hpux 7.0 and later s300. s400, s700, and s800.  
  5
  6First off,  all the standard disclaimers hold here ... HP doesn't have anthing
  7to do with this stuff.  I fool with it in my spare time because we use it and
  8because I like to.  We just happen to have a lot of HP machines around here :-)
  9Xntpd has been in use here for several years and has a fair amount of mileage
 10on various HP platforms within the company.  I can't really guarantee bug fixes
 11but I'd certainly like to hear about bugs and I won't hestitate to look at
 12any fixes sent to me.  
 13
 14Now lets talk OS.  If you don't have 7.0 or later, pretty much hang it up now.
 15This stuff has run here on pretty much everything from 8.0 upward on s300, 
 16s700, and s800.  It is known to run on 7.0 s300/s400 but all reports are 
 17from the field and not my personal experience.
 18
 19If you are lucky enough to have a s300 or s400 with 9.03, then you no longer
 20have to worry about adjtimed as HP-UX now has adjtime(2).  The rest of you
 21will have to wait on 10.0 which will have adjtime(2) and a supported though
 22a bit older version of xntpd.
 23
 24Next, let me explain a bit about how this stuff works on HP-UX's that do not
 25have adjtime(2).  The directory adjtime contains libadjtime.a and the adjtimed
 26daemon.  Instead of the adjtime(2) system call, we use a library routine to
 27talk to adjtimed thru message queues.  Adjtimed munges into /dev/kmem and
 28causes the clock to skew properly as needed.  PLEASE NOTE that the adjtime
 29code provided here is NOT a general replacement for adjtime(2) ... use of
 30this adjtime(3)/adjtimed(8) other than with xntpd may yield very odd results.
 31
 32What to do to get this stuff running ?
 33
 34    * If you are running an OS less than 10.0 or do not have a s300/s400 
 35      with 9.03 or better
 36	-> cd machines
 37	-> vi hpux
 38	-> (change -DSYS_HPUX=? to match whatever you are running [7,8,9])
 39	-> cd ..
 40
 41    * Say "make makeconfig"
 42
 43    * Say "make", sit back for a few minutes.
 44
 45    * cd authstuff
 46	* Say "./authcert < certdata" and check the output.  Every line should
 47	  end with "OK" ... if not, we got trouble.
 48	* Now try "./authspeed auth.samplekeys".  What we want to 
 49	  remember here is the "authentication delay in CPU time" 
 50	* cd ..
 51
 52    * Say "make install"
 53
 54    * I'd suggest reading the xntp docs about now :-) ... seriously !!
 55
 56    * One thing I have added to this version of xntpd is a way to select 
 57      config files if you are sharing /usr/local thru NFS or whatever.  
 58      If the file /usr/local/etc/xntp.conf happens to be a directory, the 
 59      files in that directory are searched until a match is found.  The 
 60      rules for a match are:
 61
 62	1. Our hostname
 63	2. default.<machine id> (as in default.375 or default.850)
 64	3. default
 65
 66    * Ok, make sure adjtimed is running (just start it up for now with
 67      "/usr/local/etc/adjtimed").  Using -z as an option will get you 
 68      a usage message.
 69
 70    * Now start up xntpd and watch it work.
 71
 72    * Make sure that adjtimed gets started at boot right before xntpd.
 73      We do this in /etc/netbsdsrc.  They must both run as root !!
 74
 75Possible problems ?
 76
 77    * On some 320's and 835's we have had to run adjtimed with "-p 45" or
 78      so to get rid of syslog messages about "last adjust did not finish".
 79
 80    * At 9.0, there is a problem with DIAGMON (patch available from the
 81      response center) which causes it to delete the message queue that
 82      adjtimed/xntpd use to communicate. (see next note for result)
 83
 84    * Xntpd has been known to get really ticked off when adjtime() fails
 85      which is usually only while running the emulation code on HP-UX.
 86      When it gets mad, it usually jumps the clock into never never land.
 87      Possible reasons for this are adjtimed being killed or just never
 88      started or adjtimed being completely swapped out on a really busy
 89      machine (newer adjtimed try to lock themselves in memory to prevent
 90      this one).

108Dave,
109   After reading the hpux hints file, I realized I didn't install or 
110start adjtimed.  In the course of doing this, I discovered that:
111
112--> $(TOP) is not defined in adjtime/Makefile, so "make install" can't
113    find the install.sh script.
114
115--> "make install" from the main Makefile never goes into the adjtime
116    directory, so I added the following two lines into the install
117    target of the main Makefile:
118
119    @echo installing from adjtime
120    @cd adjtime && $(MAKE) $(MFLAGS) MFLAGS="$(MFLAGS)" MAKE="$(MAKE)" install
121
122This twiddle may not be right for all systems, but it got adjtimed
123installed for me.
124
125   You might also want to add to the hpux hints file that one way to
126fire things up at boot time is to add the following lines to the localrc
127function of /etc/rc:
128
129    #---daemons for Network Time Protocol (version 3.4s)
130    #---note that adjtimed is only needed for HP-UX 9.X, not 10.0
131    #---adjtimed must be running or xntpd won't work right...
132    if [ -x /usr/local/bin/adjtimed ]; then
133        /usr/local/bin/adjtimed -r & echo -n ' adjtimed'
134        if [ -x /usr/local/bin/xntpd ]; then
135            /usr/local/bin/xntpd &    echo -n ' xntpd'
136        fi
137    fi
138
139I discovered that the "-r" option of adjtimed is needed to clear out any
140trash from a previous execution of it.  Otherwise adjtimed quietly dies
141and leaves xntpd in the lurch...
142
143Thanks for the help.
