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.
