Bob,

That's still not the problem ... I've never used RH's firewalling (I use 
monmotha's quite successfully - ie I always select none in the firewalling 
installation of RH).. and I can cross mount other disk filesystems happily, 
it's just that I get this getfh failure when the directory I'm attempting to 
mount is the where the cd mounts IE

	host_cd # mount /dev/cdrom /mnt/cdrom		# mounts locally fine
	host_nocd # mount -o ro host_cd:/mnt/cdrom /mnt/cdrom
this generates a failure on 'host_nocd' and the syslog for 'host_cd' shows a 
successfull authentication but fails with the getfh problem. If I were to

	host_cd # umount /dev/cdrom /mnt/cdrom
	host_nocd # mount -o ro host_cd:/mnt/cdrom /mnt/cdrom

this works fine .... ie I have nfs access to 'host_cd' root filesystem.

Thanks

Burn
