[rescue] fw_ntp on IRIX

[Sheldon T. Hall]

My apologies in advance if you see this more than once; I'm sending it to a
couple of lists.

I'm trying to get the current fw_ntp (from freeware.sgi.com) running on my
Challenge under IRIX 6.5.20.  It works, but it will only communicate with
_some_ of the servers it should.

I have xntpd running on Solaris 7 on a SPARCclassic, inside the same
firewall.

On the Challenge (tandem.artell.net):

/etc # ntpq -p
     remote           refid      st t when poll reach   delay   offset
jitter

4000.00

... note that it's not talking to any of the last four servers.

On the Solaris box (rtfm.artell.net):

/etc # ntpq -p
     remote           refid      st t when poll reach   delay   offset
disp

Note that the Solaris box is talking to some of the same servers that won't
talk to the Challenge.

tandem and rtfm are peers, everyone else is a server, and outside my
firewall.  I'd suspect the iptables setup on tandem, except that it is
talking to _one_ outside server.  I suspect a difference in the NTP protocol
used (SGI's fw_ntp uses V4, Sun's xntpd uses V3) but both machines can talk
to the _same_ outside server.

I'm sure I've overlooked something, but ....

Clues appreciated.

Thanks.
