Subject: xntp under DYNIX/ptx v4.2.1 & ptx/TCP/IP v4.2.0

Hi David,

Just keeping some notes since I am having to change some things to get xntp
to compile.  config.guess says "i386-sequent-sysv4", and more explicitly I
have DYNIX/ptx v4.2.1 & ptx/TCP/IP v4.2.0.  I am running
xntp3-5.90.2.tar.gz.

Two things of note.

ONE:  I had to explicitly turn off multicasting since struct mcast was not
found.  I did this by editing config.h, is there a better way?

TWO:  On line 590 of xntpd/refclock_acts.c, I reeived an error that the
variable ws not scalar.  Previous code:

                        if (pp) {
                          if (pp->lastcode) {
                            (void)strncpy(str, strtok(pp->lastcode, " "),
SMAX);
                          } else {
                            msyslog(LOG_ERR, "clock %s ACTS: pp->lastcode
was NI
L",
                                    ntoa(&peer->srcadr));
                            *str = '\0';
                          }
                        } else {
                          /* pp was NIL */
                          msyslog(LOG_ERR, "clock %s ACTS: pp was NIL",
                                  ntoa(&peer->srcadr));
                          *str = '\0';
                        }

So I changed the second line to:

                          if (pp->lastcode != 0) {

All seems copasetic, and the compile ran through to completion.

I've since been running xntpd as client and ntptrace for the past day, all
seems good.  The only interesting question I have is that I configured in
/etc/ntp.conf both a stratum 8 & a stratum 9 server.  One one machine,
ntptrace shows me both and on the second it only shows me the stratum 8.
Is this simply because of the ordering of which responded the first time
first?

server pacificbb.1dc.com
server fdt7000.1dc.com

driftfile /etc/ntp.drift

Thanks for the good software.
