What good does the first line in /etc/export do? 192.168.0.2 is 10 Mb and is only used for getting the kernel, not its root fs, so it does not need this one > Client: (casper) > > --------------------------------------------------- > /etc/fstab > > # <file system> <mount point> <type> <options> <dump> <pass> > none /proc proc defaults 1 0 > > # 192.168.0.1 is 10Mbps > # 192.168.1.1 is 100Mbps > > # first mount at 10Mbps > # <file system> <mount point> <type> <options> > <dump> <pass> > 192.168.0.1:/nfsroot/casper/ / nfs > rsize=8192,wsize=8192,nolock 0 1 > > # then remount at 100Mbps > # <file system> <mount point> <type> <options> > <dump> <pass> > 192.168.1.1:/nfsroot/casper/ / nfs > rsize=8192,wsize=8192,nolock 0 1 > 192.168.1.1:/root/ /root nfs > rsize=8192,wsize=8192,nolock 0 1 > 192.168.1.1:/home/jason/ /home/jason nfs > rsize=8192,wsize=8192,nolock 0 1 > 192.168.1.1:/boot/ /boot nfs > rsize=8192,wsize=8192,nolock 0 1 > 192.168.1.1:/usr/src/ /usr/src nfs > rsize=8192,wsize=8192,nolock 0 1 > 192.168.1.1:/usr/audio/ /usr/audio nfs > rsize=8192,wsize=8192,nolock 0 1 > 192.168.1.1:/usr/video/ /usr/video nfs > rsize=8192,wsize=8192,nolock 0 1 > > # <file system> <mount point> <type> <options> <dump> > <pass> > /dev/cdrom /cdrom iso9660 defaults,ro,user,noauto 0 0 > /dev/dvd /cdrom iso9660 defaults,ro,user,noauto 0 0 > /dev/fd0 /mnt/floppy auto defaults,user,noauto 0 0 > > ------------------------------------------------------- 2. Again, there is, as I far as I can tell, no need to mount the root fs from 192.168.0.1. By the time the kernel wants to mount its root fs, it is 192.168.1.1. That might not be the source of your "permission denied" problem though. What does seeles syslog say about attempt to mount nfs? /Hans Ekbrand
