! 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.
