k3b not mounting CD-RW drive

[NeilBlanchard]

Greetings,

I have tried on two different machines to use k3b to burn CD-R's, and it fails. It seems that it is not able to mount the CD-RW drive. I understand I can use a root terminal session to do this:

chmod 755 /usr/bin/cdrecord.mmap

However, I do not know the root password, so I am not able to start a root terminal! Can anybody help me?

[Edit: I've got it -- another thread gave me the info: on the Knoppix (penguin) menu, there is a root shell. I entered the above command there -- and k3b now works!

This needs to be part of the Knoppix FAQ! Or, the root password needs to be made known? Obviously, that is not all that secure... ]

Thanks,

Neil

read the forums, the TOP topic in one of them is just that, what is root password.
the general forum to be precise.

Greetings,

Well, I guess I missed it. I did do a Search for "root AND password" and I looked at the first 6 or 8 results, but I did not see it. My bad. Obviously it is a very common question, and obviously lots of people miss the FAQ, too. I have used SuSE and Linspire, and I looked in all the places where I thought I could get to a root console, or to the root user.

I guess I was hoping to have it as part of the introduction HTML file that pops up when you boot Knoppix; or maybe a link to the FAQ.

OK, is that all there is to using cdrecord and k3b now? I haven't been able to burn a CD since KNOPPIX 3.7, so my burner PC still has 3.7 on a hdd partition.

If I reinstall that PC with KNOPPIX 4.0.2CD, will I be able to use cdrecord doing the above fix as root?

TIA,

BTW, the stated fix above doesn't make sense to me. chmod 755 will change the permissions on that file to -rwxr-xr-x. However, in 3.7, 3.8.1 and 4.0.2CD hdinstalled PCs the permissions are already -rwsr-xr-x. Does that "s" make a difference to the non-root user???

TIA,

OK, apparently my problem was that I was still trying to use --scanbus and this is no longer necessary. I guess I got confused with the errors cdrecord returned about poor compatibility with kernel 2.6!

In older versions of KNOPPIX, I used to issue the command line:

cdrecord -v speed=16 dev=0,0,0 *.iso

after --scanbus read my burner as dev 0,0,0.

Now, with KNOPPIX 4.0.2CD knoppix-installered on a hdd partition, all I need is:

cdrecord -v speed=16 dev=/dev/cdrom *.iso

since /etc/fstab lists my burner as /dev/cdrom.
