Very Computer

Hi All!

I have a regular IDE CD-ROM drive and an IDE CD-Writer, which i will
be putting into the same fileserver, so I can do complete CD burns.
However, my question pertains to letting them live together :-)

I know how to make the CD-Writer work using the IDE-SCSI emulation
support, that's no problem.  But would this work?:

Assume:
CD-Writer = hdc
CD-ROM = hdd

So can I then make symbollic links as follows:

cdwriter --> scd0
cdrom --> hdd

And of course make the appropriate entries in my /etc/fstab:

/dev/cdwriter   /mnt/cdwriter   iso9660.....
/dev/cdrom      /mnt/cdrom      iso9660.....

(of course there would be the appropriate entires for the ide-scsi
module in /etc/modules.conf and /etc/lilo.conf).

Thanx for your help!

Ooops, sorry, one more question:

I am using Mandrake/Gnome on my workstation, and have a number of
directories NFS-monted from the fileserver to the workstation.  I
previously had the CD-Writer in the workstation, using GCombust, which
worked fine,more or less.

Will I still be able to use GCombust from my
workstation if I NFS-mount the CD-Writer to it?  IS there anything I
should be specially aware of if I do so?

Once again, thanx!

I use to have it setup like that.  Why don't you just use ide-scsi
emulation for both drives?  I use scsi emulation for both drives so
XCDRoast and other burning frontends can see the regular CDROM too.

My setup is:

/mnt/cdrw /dev/scd0
/mnt/cdrom /dev/scd1

My writer is really supposed to be on /dev/hdc, and cdrom is /dev/hdd,
if I don't use scsi emulation.

Actually, that's even better.  That will make CD-to-CD burning quite a
lot easier, which is what I want to do in the first place!

Do you know if there would be any problems if I were to NFS-mount the
drives from my fileserver to my workstation?

Thanx!

They would be read only.  You don't write to an scd device, you write to
the sg device (or the actual scsi id,dev,lun).  But you could log into the
box with the drives and burn from there (or launch an X interface like
XCDRoast that would appear on the remote box).

So if I installed the necessary X libraries, plus, say XCDRoast (or
Gcombust, or whatever), then as long as I'm running it from the server with
the CDRW onto my worksation, then it'll read the drives properly.

Since it's an internal server, protected by a pretty good firewall, I have
no problem installing X on it (hey, that's what X-Servers do anyway, isn't
it? <g>), since it's not *that* big of a security risk (it's only in the
home, too, which is no biggie).

How would the command look on my workstation to run the burning software on
the server?  I would think something like this:

server:/path/to/burning/software

Thanx again, for your help!

If you connect from the remote using ssh from an xterm, ssh can be
configured to automatically provide X11 forwarding (automatically sets up
DISPLAY at destination and XAUTH at remote where you are).  Then all you
have to do is enter the path to the X program and it will tunnel back
through ssh to appear in X on the remote.

If you just use telnet or rlogin, you would first need to use xhost on the
remote to allow the CD server to connect to X on the remote.  You might
also need to check or set DISPLAY in your enviroment on the server to
point to your remote X server before running the X program on the CD
server.  I forget if "remotehostname:0" is sufficient or if it needs to be
"remotehostname:0.0".

Hi All!

This is directed at KJ, who first gave me the idea of putting both
CD-ROMs on the ide-scsi emulation, but if anyone else knows that answer,
then even better!

I've already searched the news archives at dejanews.com
(groups.google.com), and haven't found a solution to this :-(

Okay, this is no  problem.  When I run "cdrecord -scanbus", both the
CD-RW and CD-ROM are recognized on the scsibus.  Both are on the the
secondary IDE channel (the CDRW is the master and CDROM the slave).

My setup is:
/mnt/cdrw /dev/scd0
/mnt/cdrom /dev/scd1

Except, I am able to mount CDs no problem on the CDRW, but when I try to
do so on the CD-ROM, i get the error "no medium found".  I am thinking
that the problem may lie in my /etc/conf/modules, which is:

alias scd0 sr_mod
alias scd1 sr_mod
alias scsi_hostadapter ide-scsi
options ide-cd ignore='hdc hdd'

I am thinking that the problem lies with the dual "sr_mod" aliases.  Are
there perhaps some parameters that I need to put in there, similar to
what one would normally need to do if they were using two network cards
that were exactly the same model in the same machine?  Or am I on the
wrong track here?

If someone has already done this (KJ), I'd be *very* interested to know
how this problem was solved.  Thanx!

P.S>: It's no biggie that the regular CD-ROM can't read CDs, since it's
only a 12x, and I'll only be using it for CD-to-CD burns, but I would
like to get it working :-)

Thanx, in advance.
