- Last update: Sun Mar 13 15:05:31 PST 1994
- This file hopefully describes the whatever and however of how to get xntp
- running on hpux 7.0 and later s300. s400, s700, and s800.
- First off, all the standard disclaimers hold here ... HP doesn't have anthing
- to do with this stuff. I fool with it in my spare time because we use it and
- because 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 mileage
- on various HP platforms within the company. I can't really guarantee bug fixes
- but I'd certainly like to hear about bugs and I won't hestitate to look at
- any 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 longer
- have to worry about adjtimed as HP-UX now has adjtime(2). The rest of you
- will have to wait on 10.0 which will have adjtime(2) and a supported though
- a bit older version of xntpd.
- Next, let me explain a bit about how this stuff works on HP-UX's that do not
- have adjtime(2). The directory adjtime contains libadjtime.a and the adjtimed
- daemon. Instead of the adjtime(2) system call, we use a library routine to
- talk to adjtimed thru message queues. Adjtimed munges into /dev/kmem and
- causes the clock to skew properly as needed. PLEASE NOTE that the adjtime
- code provided here is NOT a general replacement for adjtime(2) ... use of
- this 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).

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