I'm trying to run xntp3 under AIX/370 1.2.1 (PL 1400).

I know that this system is going, but we will have it here
at least for the next six months here and I would like to run
xntpd under it.

I compiled xntpd succesfully (so seem at least), but it seems
to hang. What I can see is that it seems that xntpd is
not receiveing any packet or at least <getrecvbufs> is
always called without anything to do.

More I tried ntpq and xntpdc with other servers and they
work but I cannot obtain any answer from the xntpd running
under AIX/370 (both from the same host than from others).

I compiled xntpd with bsdcc (it is anologous to the one in
AIX/6000: BSD compatibility include files and libs at
the level 4.3 I believe).

One of major doubt is about the fact that xntpd use ASYNC
I/O on udp socket by default. I'm not completely sure AIX/370
can handle them (fcntl man page is not completely clear at
this purpose). I tried to compile xntpd with -DUSESELECT
(as for the Sequent), but it answer to the first few packets,
the hangs again.

So now I'm out of hope: I don't know so deeply udp sockets
to extensively debug xntpd. 

One last think: I tried to define -DNODETACH (I saw something
in ntpd.c suggesting this for Apollo). Same result: hang.

I hope someone in the Network may have better advice than me,
or maybe I'm so lucky someone else already compiled xntpd
for AIX/370 (I don't hope that so much).

If someone "solved" a similar problem for other platforms
and gan give some hint I will be forever gratfully to him.
