Think of ntpdate. Which is exactly what it did the last time I studied that startup script in /etc/init.d. It runs ntpdate once to crash synch the clock, and then runs the ntpd. >Why not just use ntpdate?

Anyway... I agree, however retiring such a usefull tool might be desirable from the standpoint of being replaced by a better way, possibly built into ntpd, but I've not noted any discussion about it. And I'm of course not on a mailing list that would make me privy to that either. I would hope that they would make an attempt at advising the users that there was a change coming first. >Both the stock ntpd and openntpd have features which should bring >the clock to good time as soon as they get a good feed from one or >more of the servers for which they are configured to use. ntpd -gq, >in theory, should not be needed if either ntpd is going to be run as >a daemon. > >That being said, my experience (with both the stock ntpd and >openntpd) is that it is best to do a gross adjustment first (whether >by ntpd -gq, ntpdate, rdate, etc.) *then* start the daemon.

In Anne's case, that can't be assumed. Probably because its miss-configured in ways I'm not familiar with since I don't yet use wpa_supplicant, in fact its all done by the network script on my lappy. The WEP key is actually listed in my /etc/sysconfig/network-scripts/ifcfg-wlan0 using the KEY=syntax but I have NDI if the WAP(2) key Anne is using could be similarly defined there or not. It might be worth a try, Anne. >I hope this helps, thanks, > >Joe >-- >E-mail: joe.barnett@xxxxxxxx >Web: http://www.mr72.com/ >AOL IM: JoeBarnett >Phone: 623.670.1326 -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
