Accessing a CD-ROM drive via Linux NFS in a diskless machine - help needed

Post by Muthuvelu mv.. » Sun, 25 May 1997 04:00:00

Hello folks,

I am muthuvelu from Madras - India. I am a Unix affectionade and using \
flavours of unix. I am using slakware distribution of linux.

I have a different requirement and if anybody could help me, i will be
very much thankfull to them.

Here is my requirement.Very offen i need to transfer a large amount of data
from one machine to other machine. ie I will be getting MB's of data in a
Recorded-CD(CD-R) and i needed to transfer it via network to few servers for
processing.most of the time i will be using a machine without harddisk but
with IDE-CDROM and 1.44 MB FDD. since we have involved in multimedia projects
we have CD-ROM installed in quite few machines and it will be remotely booted.

Now the thing is i wanted the CD-ROMs in any of the machine has to be accessed
via NFS, so that i can transfer the contents of CD-ROM. Though i have different
methods i think this will solve many of my headaches. I visioned the scenorio
like this. ie

I should boot the machine in linux with NFS support via 1.44 FDD and the CD-ROM
has to be mounted in NFS.What i will do is i will mount this CD-ROM thro my
network and transfer the entire CD content via NFS.

So What i require is a kernel and a root file system with NFS support.
How do i make this. What procedure i have to can i configure.
Pls remember i don't have harddisk in any of the machines.

So if any body who has come-across similar situation or anyone who can

very much thankfull to them

I don't have frequent access to news-groups, so pls reply me in e-mail

Looking forward to receive the valuable soultion

With Regards,



1. CD-ROM, mounted via NFS on a remote machine access denied

When I mount the CD-ROM to my directory "/usr/kit" or to any other, I have
no trouble viewing the contents of the CD-ROM on the local machine.

When I mount the "/usr/kit" directory on another SCO Box or even a Win
3.11 client I can do so, as long as the CD-ROM isn't attached to it.
If the CD-ROM isn't mounted to the "/usr/kit" directory, then mounting is
easy and painless.  If the CD-ROM is attached the remote device says
"access denied".

I tried attaching the Win3.11 first then the CD-ROM, no errors, and no
information from the ROM.

I have checked and verifed the "showmount -e" does in fact return:

/usr/kit   (everyone)
/pub/cdrom (everyone)

Are there any better ways to work on the CD-ROM to be seen on the network,
I have tried several other directories and have checked that they to are
in the "/etc/exports" with world access.

This happens on either machine:

OpenServer 5.0.2
OpenServer 5.0.4

They both have NFS and function just great with mounting any
directory, as long as the CD-ROM isn't attached to it.

What did I miss ?
