This scenario makes maintaining synchronization difficult. ntpd seems to expect that you will be connected permanently, and in my experience if it can't contact its time servers for some period of time, it will die. You could keep the clock mostly pretty up-to-date by using ntpdate in your connection script, and then using the hwclock command to set the hardware clock to the new time. You could also do this in a script run periodically by cron. In that case, the synchronization would fail whenever you're not connected, but as long as the machine is up and connected so that it runs successfully once or twice a day, your clock should be kept pretty accurate. > I assume ntp will do this for me if I configure it correctly, and I > would prefer to use ntp because I have virtual machines that I would > like to synchronize to the host machine. I assume you mean something like VMWare running on the same machine? If you should happen to have other machines on your network which are always connected to the Internet somehow, then a much better option would be for you to run ntpd on one of those hosts, and synchronize against that. May not be an option for you though. - -- Derek Martin [EMAIL PROTECTED] - --------------------------------------------- I prefer mail encrypted with PGP/GPG!
