[KLUG Members] clock synch

[bill]

That's the ticket.  Works fine.  The ntpd wasn't working, even though I tried to set it
several ways (from command line and from gui).  Makes me wonder if it isn't the firewall
blocking it.

As long as I'm root, the rdate works fine.  Putting it in cron is perfect.  I'm thinking
that if I want to use more than one timeserver, just add a few more lines to cron.

I also got around to replacing the CMOS battery.  When your clock is -way- off, using
cron to fix your clock is rather circular reasoning.

thanks,

bill
