Using CD drives?
« on: September 21, 2005, 04:44:05 pm »
Alright, I have Slackware. I have two CD-ROM drives. I'm probably going to be using KDE instead of WMaker. Anyhow, how would I mount D: to /mnt/cd1 and E: to /mnt/cd2? Or would it be /mnt/cda1 and /mnt/cdb1, being two totally different drives?

Offtopic:
Also, Linux has an autoexec.bat-type shellscript to start programs on kernel startup, right? Where is this, if so?

Note: This post is set in the future. I stil don't have Slackware.

I'd personally do as Joe suggests

You might be right about that, Joe.

Your cd drives, assuming they're ide, will be in /dev/hda, hdb, hdc, or hdd.  To figure out which one is which, do "dmesg | grep hda", "dmesg | grep hdb", etc.  That should give you the information you need. 

In Linux, the "kernel startup" is the first couple seconds.  All the rest is programs being run and modules being loaded.  Pretty much everything you see while it's booting is programs/shellscripts outputting their stuff.  Depending on what you want to do, you want your stuff to run at different points during startup, which you can check out in the /etc/rc.d/ folder.  If you view each file in there (especially rc.0, rc.1, etc.) they'll tell you what happens when. 

The easiest way is to put your programs in /etc/rc.d/rc.local.  As it says in its comment, rc.local is the last script to be run on boot.

Interestingly enough, the 250GB HDD I ordered for my server just came in today.  I didn't even have to ask for help -- it was already here!

/dev/cdrom is linked to your main CDRom most of the time.

newby@impaler:~$ ls -l /dev/cdrom
lrwxrwxrwx  1 root root 8 2005-07-03 15:21 /dev/cdrom -> /dev/hda

I'd bet that you're currently bloated like a water ballon on a hot summer's day.

That analogy doesn't even make sense.  Why would a water balloon be especially bloated on a hot summer's day? For your sake, I hope there wasn't too much logic testing on your LSAT.

Alright, slick! Also, how well does this handle removing+inserting different CDs?

/dev/hda1 = C:\
/dev/hdb1 = D;\
/dev/hdc1 = E:\

Setup:
*login as root*
cd /mnt
mkdir cd1
mkdir cd2

On box start:
mount /dev/hdb1 /mnt/cd1
mount /dev/hdc1 /mnt/cd2

Right?

No.

/dev/hda = CD-Rom for me ("D:")
/dev/hdc = CD/DVD-Rom for me ("E:")
/dev/sda = Hard-drive
/dev/sdb = Hard-drive

/dev/sda1 = Windows partition ("C:")
/dev/sda2 = Linux partition (/)
/dev/sdb1 = Windows Partition ("S:")

Again, it will differ on your system.

Most of the directories come premade with your Slackware installation. I made dvdrom for myself, but cdrom was already there.

newby@impaler:~$ ls /mnt
cdrom/   external/  hd/    old-drive/   windows/
dvdrom/  floppy/    ipod/  thumbdrive/

/etc/fstab can link some of the drives to a specific mount point if you wish.
newby@impaler:~$ cat /etc/fstab | grep "cdrom"
/dev/cdrom       /mnt/cdrom       iso9660     noauto,owner,ro  0   0

You really don't want to mount a drive on boot. That's just retarded.

Mount them when you stick a CD in. Unmount (umount) them when you don't.

See, Joe, this is why you weren't a moderator of this board. This is really just a basic of *nix. As much as you may be relatively knowledged in *nix, you aren't totally knowledged enough to moderate issues revolving around it. You are all knowledge, hardly any experience. :)

Ok, so that's the harddrive.  Now what do I do to access it?

I'm guessing you need to partition it...
cfdisk /dev/hdb/

Then mount it
mount /dev/hdb1 /mnt/location
mount /dev/hdb2 /mnt/location2
etc.

* Ergot laughs at Joe. ^^

Don't forget to make a file system on the partitions!

Another problem.  Maybe I'm stupid?

root@tehserver:~# mount /dev/hdb1 /mnt/hdb1
mount: mount point /mnt/hdb1 does not exist

You should do ext3. It's journaling!
