Do I need to put it in rc[3-5].d also? Yes, that certainly doesn't hurt. rcS is run not for every level, but once at boot. So, if after booting into run level 3, you then change to run level 5, scripts in rcS are not rerun - only the kill scripts in rc3 and the start scripts in rc5. > >The more complicated answer is to run ppp from ifupdown, so it starts > >earlier in the boot process. > > Which brings up another question.

Is there a way to do that with init so that I can see exactly > which command is starting PPP? It seems like ifupdown _is_ starting PPPoE. I think /etc/default/bootlogd should have a BOOTLOG_ENABLE or something, to at least log boot up events beyond the kernel and init messages - this will help recreate what the scripts are doing. Another way would be to add echo statements to the init scripts you care about. I doubt ifupdown is starting ppp, from your description, or at least not doing it well, since you have no network when ntpdate runs. That implies to me the network is only brought up later by the ppp init script. There is, though, a known problem with starting ppp from init scripts - the pppd command returns control to the calling process after daemonizing, but before networking is actually brought up - this makes it difficult for init scripts to decide to move on or not. Most people have so far just ignored this problem, but it does make things like this trickier to debug. -- -------------------------------------------------------------------------- | Stephen Gran | You may be marching to the beat of a | | steve@lobefin.net | different drummer, but you're still in | | http://www.lobefin.net/~steve | the parade. | -------------------------------------------------------------------------- Attachment:
