Thanks Proto and Chadwick

Actually I don't force ntpd to use IPv6. Hostnames could be resolved to any
IPv4 addresses. I have no problem with that.
The only thing I want is ``synchronization''.

I have tried it, still not work.

# tcpdump -l -n -s 8192 -p "port 123"
tcpdump: listening on fxp0, link-type EN10MB (Ethernet), capture size 8182 bytes
0 packets captured
12 packets received by filter
0 packets dropped by kernel
^C
(after awaiting around 20secs then hits interrupt)
You are right, I didn't get any responses.
I have doubly checked. Firewall on my router/gateway is disabled, not active.
I have also tried disabling firewall on my machine.
It still doesn't work.
Actually I am not suspecting my /etc/ipfw.rules, which has been being used
for long since FreeBSD 5.4. ntpd has never encountered any problems for such
ipfw configuration with dial-up (both 5.4-RELEASE and 6.2-RELEASE).
(I also didn't forget to change interface name from dial-up to ethernet.)

I have tested it, I still get outdated man pages.
I even dive into /usr/src/share/man.
Man pages over there are all FreeBSD 6.2.
But some timestamps dated Feb 13, 2008; but footer is still FreeBSD 6.2

I want them to be compatible with the current version of FreeBSD.
So I will not use it, thanks.

No, but I perfectly followed instruction in handbook.
# cvsup -g -L 2 /usr/share/examples/cvsup/stable-supfile
backup data and /etc
read /usr/src/UPDATING
# mergemaster -p
# shutdown now (drop to single user)
# fsck -p
# mount -u /
# mount -a -t ufs
# swapon -a
# adjkerntz -i
# cd /usr/obj
# chflags -R noschg *
# rm -rf *
# cd /usr/src
# make [-j4] buildworld
# make buildkernel KERNCONF=SMP
# make installkernel KERNCONF=SMP
# shutdown -r now (reboot the new kernel in single user mode)
# make installworld
# mergemaster
# shutdown -r now (reboot the new system)
# uname -a (show the new kernel)
And I also look in some forums.
I think that the procedure above is correct.
I also got many new man pages in /usr/src/share/man,
but as said all are 6.2 (with some new timestamps).
If so, archives in cvs repository (cvsup.th.freebsd.org) are probably outdated.
If I did anything wrong, please tell me.
Please note that I have been using FreeBSD since 5.0. But I ALWAYS install
new system from iso image. This is my first time updating from source.
And what about updating handbook?
# cvsup -g -L 2 /usr/share/examples/cvsup/doc-supfile
# cd /usr/doc (many dirs/files in here, like sgml files)
# make all install (or) make install
It just doesn't work.
I don't want to waste your time; it is also irrelevant to freebsd-stable.
Please just give me a brief hint.
Thanks,
Pongthep
