I used to run chrony (with difficulty) but ran into a problem with my new box: it couldn't access the hwclock. If I told it not to, (so that the hwclock shutdown script could work), it really messed up my time. So I switched to ntp. I access the net with ppp and put a script into ip-up.d to restart ntp when the link comes up. Yes, ntp will jump instead of skew since a skew can take a __very__ long time to accomplish. With fewer and fewer people using dial-up I feel a bit orphaned at times and ntp/chrony is one of them. Doug. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
