ntp 4.2.6p5

    1: Last update: Sun Mar 13 15:05:31 PST 1994
    2: 
    3: This file hopefully describes the whatever and however of how to get xntp
    4: running on hpux 7.0 and later s300. s400, s700, and s800.  
    5: 
    6: First off,  all the standard disclaimers hold here ... HP doesn't have anthing
    7: to do with this stuff.  I fool with it in my spare time because we use it and
    8: because I like to.  We just happen to have a lot of HP machines around here :-)
    9: Xntpd has been in use here for several years and has a fair amount of mileage
   10: on various HP platforms within the company.  I can't really guarantee bug fixes
   11: but I'd certainly like to hear about bugs and I won't hestitate to look at
   12: any fixes sent to me.  
   13: 
   14: Now lets talk OS.  If you don't have 7.0 or later, pretty much hang it up now.
   15: This stuff has run here on pretty much everything from 8.0 upward on s300, 
   16: s700, and s800.  It is known to run on 7.0 s300/s400 but all reports are 
   17: from the field and not my personal experience.
   18: 
   19: If you are lucky enough to have a s300 or s400 with 9.03, then you no longer
   20: have to worry about adjtimed as HP-UX now has adjtime(2).  The rest of you
   21: will have to wait on 10.0 which will have adjtime(2) and a supported though
   22: a bit older version of xntpd.
   23: 
   24: Next, let me explain a bit about how this stuff works on HP-UX's that do not
   25: have adjtime(2).  The directory adjtime contains libadjtime.a and the adjtimed
   26: daemon.  Instead of the adjtime(2) system call, we use a library routine to
   27: talk to adjtimed thru message queues.  Adjtimed munges into /dev/kmem and
   28: causes the clock to skew properly as needed.  PLEASE NOTE that the adjtime
   29: code provided here is NOT a general replacement for adjtime(2) ... use of
   30: this adjtime(3)/adjtimed(8) other than with xntpd may yield very odd results.
   31: 
   32: What 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: 
   75: Possible 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).

  108: Dave,
  109:    After reading the hpux hints file, I realized I didn't install or 
  110: start 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: 
  122: This twiddle may not be right for all systems, but it got adjtimed
  123: installed for me.
  124: 
  125:    You might also want to add to the hpux hints file that one way to
  126: fire things up at boot time is to add the following lines to the localrc
  127: function 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: 
  139: I discovered that the "-r" option of adjtimed is needed to clear out any
  140: trash from a previous execution of it.  Otherwise adjtimed quietly dies
  141: and leaves xntpd in the lurch...
  142: 
  143: Thanks for the help.
