You should propagate the PPP startup script before the NFS mounts occur. This is a site specific configuration that probably isn't that common. Never the less, I think Debian 1.2 will probably deal with this better (I think). In the mean time, you can customize the init.d/network script to call your ppp startup script instead of running it out of rcX.d (where X is the run level). I don't have a Debian system in front of me right now (mine's floating in the Pacific at the moment :-)), so this is the best I can do. This should get your ppp up prior to going to the mount phase. A better solution may be to use the noauto option for NFS mounts and include a separate NFS mount script in init.d and link it to something later than the PPP script in the rc directory. That would save you from modifying init.d/network. It would also enable you to configure runlevels that do not use ppp, or NFS mounts, etc. Again I don't have a Debian system in from of me right now, so I don't know how this is handled in 1.1 out of the box for sure. > > I have a similar problem on shutdown, my ppp is killed when the scripts in > /etc/rc6.d are run, but the nfs filesystem is still mounted.

This seems to be a very popular problem. Debian, RedHat, Slackware, SunOS, Solaris, Irix all kill all processes prior to unmounting filesystems. The theory behind this is that if a filehandle is open on a filesystem, it can't be unmounted. The problem is when the process killed is ypbind or pppd and you can't resolve the hostname of the NFS server. I think Solaris 2.5+ has a functional fuser command that could be used to kill all processes (close all open filehandles) on a mount point. The shutdown procedure could then kill processes on NFS mounted filesystems first, unmount NFS filesystems, then do its normal routine of killing all processes and umounting all filesystems. Anybody know if Debian's fuser command supports this? Anybody got any other ideas here? > > So is there a better way to set up a dedicated ppp link than what I'm > using?

How does this script handle the open filehandles issue on NFS mounts? Do you have a copy of the script? Thanks Richard G.
