Just for curiousity, you can change it. /etc/hosts is a link /etc/hosts -> ../var/tmp/hosts you can edit but you cannot permanently save it. cat /etc/hosts 127.0.0.1 localhost 192.168.178.1 fritz.box 217.10.79.8 0.europe.pool.ntp.org ntp.sipgate.de Now I dont bother pool.ntp.org but ask my sip provider. That trick might work for the D-Link too. Of course 0.europe.pool.ntp.org is alright but that ntp server D-Link has is not. You have to insert the hostname plus ip into /var/tmp/hosts or the box will ask DNS. Cheers Peter and Karin Peter Dambier wrote:

I could not find a config file. Compiled into "/sbin/multid" ? I guess similar devices like the maudit D-Link are much the same. Only that multid deamon seems to be AVM specific. If that NTP thing is from the nondisclosed und unGPLed TI source then best forget about it. Replace it by somewellknown software that is known not to be nasty. Another router that is not compatible and not especially a good router - has an html interface where you can put it your favourite NTP server. I still wonder why I cannot configure the NTP server but at least it is not as nasty as the D-Link. Peter Stephane Bortzmeyer wrote:On Tue, Apr 11, 2006 at 10:01:10PM +0000,Edward B.

The disadvantage is, of course, that you may occasionally get a bad server and that you usually won't get the server closest to you. The workarounds for this is respectively to make sure you configure at least three servers in your ntp.conf and to use the country zones (for example 0.us.pool.ntp.org) rather than the global zone (for example 0.pool.ntp.org). Read more on using the pool.The pool is now enormously popular, being used by at least hundreds of thousands and maybe even millions of systems around the world.The pool project is now being maintained by Ask Bjørn Hansen and a great group of contributors on the mailing lists.
