What CDemu is:
< There is an easier way to mount ISO files only. But the easy way works on ISO files only. With cdemu you can amount bin/cue img iso etc etc CDemu is just a kernel module.

How to get CDemu: < If you use Gentoo Linux (as I do) you can simply run: emerge cdemu If you use debian it's most likely in apt-get. Which you can get via apt-get install cdemu If you don't have debian or gentoo here's how you get cdemu: Open a terminal program Login in as root and wgt the files you need: $ su - # cd ~ (just to check if you're in home) # wget h**p://robert.private.outertech.com/virtualcd/cdemu-0.7.tar.bz2 Now uncompress the files: # tar -xjvf cdemu-0.7.tar.bz2
Build and Installing CDemu

Side note: If you are fairly new to Linux and you get problems making/installing cdemu due to it not finding your kernel
source, you need to install kernel source. If you use Mandriva Mandrake Redhat or basically any Linux OS you can buy prepackaged at Best Buy, you need to install the kernel source.
Running uname -r will tell you what kernel version you have, and you either need to build your own kernel (which if you're new to Linux isn't going to be fun but it's worth
the learning experience) OR you need to install the kernel source package in whatever package manager you have.
< # cd cdemu-0.7 # make # make install # modprobe cdemu Doublecheck to see if it loaded: # lsmod | grep cdemu Unfortunately we aren't done yet. Now we have a kernel module installed. But it won't load on boot. Here's specific instructions if you run Gentoo Linux ONLY: (scroll down further for general Linux install instructions) If you use kernel 2.6: # echo "cdemu" >> /etc/modules.autoload.d/kernel-2.6 If you use kernel 2.4 # echo "cdemu" >> /etc/modules.autoload.d/kernel-2.4 Then run (as root) #modules-update Instructions for generic Linux systems: See if /etc/rc.d/rc.modules exists: # ls -l /etc/rc.d/rc.modules If it does, it will return the filename with permissions etc. Next add the module to boot # echo "/sbin/modprobe cdemu" >> /etc/rc.d/rc.modules If you dont use devfs or udev or something you have to run # /etc/mkdev cdemu0 # /etc/mkdev cdemu1
Usage
< Okay so now go into to the directory where your cue/img/iso file is: # cdemu 0 haha.cue This loads it into cdemu device 0. Which is /dev/cdemu0 If it's a SVCD or VCD you can run VLC media player and go to File : Open Disc and put the file type and /dev/cdemu0 If it's not SVCD or VCD and is data, you can always: # mount /dev/cdemu0 /mnt/cdrom #cd /mnt/cdrom The cool thing is if you have 2 cds. You can extract both of them and mount one to device 0 and the other to device 1 and just change the disc source from /dev/cdemu0 to /dev/cdemu1. To unload an image you can run: # cdemu -u 0 Look for more tutorials by me in the near future. Enjoy.

Thanks for the information, I was looking for something like this

How do you mount a image if you dont have a cue file?

Look at the contents of a cue file. You can easily create something similiar.
As for that error. Simply make a device (I use udev so I don't have to)
run
#/etc/mkdev cdemu0
etc
I will add this to the tutorial

I use udev as well but still no luck

For gentoo just run
emerge cdemu

It should add devices for you already.

Also make sure the kernel module is loaded.

Nice tutorial mate... ive been running linux for a while and knew how to do this.. where i came unstuck was "unmounting" the iso's when i deleted the source.. when i stopped playing the game or got bored or whatever.. its nice to get the system back to how it was.. perhaps you can add this in your already very good tutorial..

Cheers

Ah thanks for reminding me.
The command is:
cdemu -u 0

If you mounted the image with cdemu you have to unload it with cdemu.
