[etc] Howto Synchronize two machines

Hi,

 It seems that our ntp server on the experimental network is not working.
 So I synchronized the clock of 'ntttest' with EVL's clock via 'alpha'.

 The distribution of the time is as follows.

 EVL's ntp -> alpha -> ntttest

 Probably, it takes a few hours to stabilize this synchronization.

 And the followings are instructions for setting ntp on FreeBSD 2.X.

     (1) edit the lines associated with 'ntp' in /etc/rc.conf

         xntpd_enable="YES"     # Run xntpd Network Time Protocol (or NO).
         xntpd_program="xntpd"  # path to xntpd, if you want a different
one.
         xntpd_flags="-p /var/run/xntpd.pid"  # Flags to xntpd
         tickadj_enable="YES"   # Run tickadj (or NO).
         tickadj_flags="-Aq"    # Flags to tickadj (if enabled).

     (2) edit /etc/ntp.conf ( configuration file for xntpd )

         server 131.193.48.81         # ( is a ntp server )
         peer 127.127.1.0             # ( see below )
         driftfile /var/run/ntp.drift # ( drift file )

         ** if the command 'peer 127.127.1.0' is set, xntpd uses local clock
            when the server's clock is not available.
            If you want to configure a PC just as an ntp client, this is not
            needed.

     (3) reboot

     (4) wait 5-10 minutes until the xntpd get stable.

     that's it.
