Re: Setting the clock
Boot in MacOS and change it. Not nice but it does the job. Otherwise, I haven't succeded in the past to make linux remember it after a reboot by using the gnome clock applet, mcc or the command line. It's fine as long as I don'T reboot. So it's a reason to keep MacOs on the drive. P. > > De: "Alex Horvath" <[EMAIL PROTECTED]> > Date: 2003/03/27 jeu.

You could hack the ntpd initscript to run it before the daemon. rc.sysinit is probably too early. -- Stew Benedict -- MandrakeSoft PPC FAQ: http://www.linux-mandrake.com/en/ppcFAQ.php3 IRC: irc.freenode.net #cooker-ppc Archives: http://marc.theaimsgroup.com/?l=mandrake-cooker-ppc&r=1&w=2

Re: Setting the clock
OK, fist, no X on this machine, it is strictly a router with CLI. Second, got ntpdate to work, so I now have the correct time. I think I can do it this way, if someone can help me on how to program it. use ntpdate to set the clock BEFORE loading ntpd, otherwise ntpdate will fail saying that the ntp socket is already in use. Question is, where should i put the command for ntpdate so it gets executed (preferably right after the internet stuff is loaded) before ntpd ?

Re: Setting the clock
Hi, Remember that ntp does not like changing the clock by very much -- it is designed to correct a small difference in frequencies, not huge jumps. If it crashes and the time is wrong by more than ~5mins it will NOT sort you out. In KDE a right-click on the time will give you an option [for root] to change the time. I believe that "date" can be used to set the time, but I have to look up the syntax every time. I thought that ntp would correct a jump during the boot sequence, if not then try /usr/sbin/ntpdate server; OR rdate -s server followed by hwclock --systohc to do the trick. Once you have ntp setup it is worth checking the "quality" of your time with /usr/sbin/ntptrace.

Re: Setting the clock
If you have always on internet, you could consider installing a ntp client. Installing the rpm should either create, or set permissions for the clock so that you can access it at a later point, or have it execute on connect to your ppp account. - Original Message - From: Alex Horvath To: [EMAIL PROTECTED] Sent: Thursday, March 27, 2003 4:42 PM Subject: Setting the clock Silly question, but how do I set the clock on the computer.
