[HECnet] Multinet 5.5 issues on VMS 7.3 (VAX) under SIMH

[Keith Halewood]

Hi Supratim,

I just added server entries to google so my ntp.conf is initially:

driftfile MULTINET:NTP.DRIFT
statistics loopstats peerstats clockstats
filegen loopstats file loopstats type day enable
filegen peerstats file peerstats type day enable
filegen clockstats file clockstats type day enable
server time1.google.com burst iburst prefer
server time2.google.com burst iburst prefer
server time3.google.com burst iburst prefer
server time4.google.com burst iburst prefer
restrict -4 default kod notrap nomodify nopeer noquery limited
restrict -6 default kod notrap nomodify nopeer noquery limited
restrict 127.0.0.1
restrict ::1
restrict source notrap nomodify noquery

When I start NTP, I eventually see this in the logfile:

$ Set NoOn
$ VERIFY = F$VERIFY(F$TRNLNM("SYLOGIN_VERIFY"))

The command 'multinet ntpq -p' gives me:

$ multinet ntpq -p

==============================================================================

%SYSTEM-F-OPCCUS, opcode reserved to customer fault at PC=000856D9, PSL=03C00000

  Improperly handled condition, image exit forced.
....and a signal, stack and register dump.

So... I'm a bit stuck still. Any pointers (preferably not null ones :) ) gratefully received.

Keith

Hi Keith,

Hi,

Is anybody running the NPTD functionality in Multinet 5.5 on VAX VMS 7.3 (under SIMH)? If so, how did you get it to work. I switched it on with a simple NTP.CONF and tried to query it. The logfile doesn't change much and I/O counts go up slowly. My attempts to query it usually result in a traceback. I'm a bit concerned by the lack of an NTPDATE command mentioned in the documentation, despite having done a full install. The timezone facility is a bit primitive too.

Works okay on multiple SIMH OpenVMS/VAX 7.3 instances. Here is what I get:

$ multinet ntpq -p

And here is my MULTINET:NTP.CONF; 10.42.0.0/24, 10.100.0.0/24 and 10.200.0.0/24 entries are my local subnets with unrestricted access. Also I run my own public NTP servers, but any good public servers should work. You can just have the pool entry if you want.

I'm thinking of giving up with it. I have local TCP services on the machines hosting SIMH instances. One of them returns a local time string in VMS format, so I may make use of that in an RDATE-like fashion.

Keith

Hope this is of some help.

Best,

Supratim
