Comments please... I'm using NFS + AMD but I think that just detects the problem, rather than being the cause of the problem. On Host=rain: cp /host/flip/usr2/ew/cdrom.iso cdrom.cd while the CDROM image is copying across my home 10Mbps ether ((ready for later burning) & while nothing else is causing ethernet disruption) On Host=flip vnconfig vn0 /usr2/ew/cdrom.iso mount -t cd9660 -r /dev/vn0c /mnt As soon as I push return on the host=Flip mount command, on Host=rain I see the error message: cp: /host/flip/usr2/ew/cdrom.iso: Permission denied Yet starting the cp again just after succeeds ... So something is momentarily making the image unreadable. Should FreeBSD [mount/kernel ?] be changed to avoid denying access ? I tried again using ftp get on Rain, & ftpd on Flip. That works, & md5 says copy is OK, no big suprise, ftp of course copes better with transient interruption / non availability.
