questions about ISC 386/ix

[Joachim Ott]

I have 3 little questions about ISC 386/ix:

1) I'm root on host alpha and enter the following commands:

mount -f NFS beta:/ /mnt
dd if=/mnt/dev/dsk/f0q15dt
dd: read error: Permission denied
(same for cp, tar, /mnt/dev/dsk/f0q15dt is 666-mode)

In my opinion, the floppy should be part of the mounted filesystem.

2) Still root, I enter:
cd /tmp
>z
ls -l z
-rw-r--r--   1 root 	root 	0  Jan	4 19:01 z
cd /mnt/tmp
>z
ls -l z
-rw-rw-r--   1 65534	other	0  Jan	4 19:01 z

What about that funny user-id and 664-file-mode on host beta ?

3) What are /lib/idcpp and /lib/idcomp good for ? They differ from
cpp and comp in 2 bytes length ('id' in the name in comment section).
They are not noted in the manual or I haven't found the page yet.

Anybody out there who knows ? Send followup to this group.
