some cd-burning problems
Greeting, I found that I had some cd-burning problems with cdbakeoven and k3b. When I try to use these programs to copy my cd, it occurs errors. In cdbakeoven (ver 1.9.9+2.0.0beta2-2), I got the following message which is unreadable: Culculating size of CD. Please wait Size of this CD: 627MB. Directory '/home/bbns/' has 8536 MB available.

Access to the daemon is controlled by standard methods (firewall, tcp wrappers, etc.); Er, maybe. You mean because the daemon runs as root? Then it just places the permission problem somewhere else: with the daemon. There should always be a way to go without daemons in any case (if you're just using the writer locally). Right but a daemon is much more flexible how do deal with authorization and access rights. Having to logout/in from/to X session to activate new group group member ship is something like rebooting Windoof after every software installation. Stupid but necessary (and no: su/ssh etc is no good solution of Mum and Dad). I'm really curious what solution the debian desktop project will develop. c) it allows the use of the recorder by users in other machines.

It's a java applet client-side and a daemon that operates cdrecord server-side. I use this approach for CD readers, floppy drives, scanners, printers, zip drives, but I cannot do it for CD recorders :-( :-( Floppy drives? without mounting them on the server you mean? how? with floppy:/a and mtools one can work with floppies without mounting them.

In the process we could perhaps get rid of scsi emulation... Uh-oh... and now comes the argumentation today, we all have pretty big machines so we can afford to make an overhead-producing daemon :-/ I like cdrecord for its power, flexibility, performance, stability and low system requirements.

But you do not really want that to users,you cannot trust ultimately, because suid-root in this case allows it to specify anything as dev= in cdrecord command line: overwriting any scsi device is nice for harmful things... The thing for cdrecord is, that it cannot use /dev/something but needs really raw access to the device (I hope this to come in kernel 2.6) because the sg* devices do not allow this. THATs the reason why it has to be setuid-root and it is really a kernel thing to change that. Using ATAPI-CDRWs is already possible (special kernel versions and a cdrecord patch is needed IIRC). On-top-of-cdrecord programs like XCD-Roast then approach the whole thing wrong: there is no need for them to be setuid-root when the cdrecord binary already is. But as this is not always the case (see above why maybe not), again they have to have root rights to call cdrecord. After all, the situation is there due to a lack of kernel abilities.

CD burning without root priviligdes
Hello Is there any KDE gui tool to burn CDs, that can work without root priviledges? I need it for linux terminal application server. Users should be able to write CDs without knowing root password! I may make cdrecord setuid, but I don't want any gui running as root! cdbakeoven can be started as normal user, but many operations seem not to work (e.g. access to previous session). k3b asks for root password on startup. The only tool that works is gcombust, but it's interface is ugly.
Re: CD burning without root priviligdes
Hi, I use Xcdroast version 0.98alpha10 (the latest for the moment) and it has a non-root mode which is running pretty well. For debian I had to install it from sources, but it went well.

All user permissions on my system are set correctly. I am a seasoned sysadmin, after all. Polansky's Pointer: If they're absolutely sure it's not there, it's probably there. (Gerald M. Weinberg, More Secrets of Consulting) The GUI CD-burning apps I know of (cdbakeoven, K3b, koncd, kreatecd) don't themselves need special privileges. They are just frontends for cdrecord and cdrdao. But these later programs do need root privileges or work better if they've got them. K3b is a bit special in this regard. It includes a setup tool that needs to be run but once. This tool does need root privs, but only once. It sets the permissions of cdrecord et al. to 4710, creates a group for cd-burning and adds some users to this group. My advice to anyone interested in using K3B on debian is, to use this tool for the basic configuration of K3b, but *don't* have it change your fstab, groups and permissions. As far as groups go, there's cdrom already there on debian. And permission changes of packaged files are supposed to be recorded with dpkg-statoverride. So, even if you're sure that all your permissions and groups are set up properly, check out if they're something like this: -rws--x---1 root cdrom 532292 Oct 16 01:58 /usr/bin/cdrdao -rws--x---1 root cdrom 250120 Sep 27 22:42 /usr/bin/cdrecord -rws--x---1 root cdrom 405352 Sep 27 22:42 /usr/bin/mkisofs lrwxrwxrwx1 root root4 Mar 10 2001 /dev/cdrom - scd0 brw-rw1 root cdrom 11, 0 Jun 27 2001 /dev/scd0 crw-rw1 root cdrom 21, 0 Apr 6 2001 /dev/sg0 (Assuming ide-scsi emulation.

Re: CD burning without root priviligdes
Thank you for your explanation. I didn't know that k3b wants root privs only once (is that mentioned on their website?). I just compiled it, started as user and it asked for root password. I got angry and removed k3b immidiatly. Recompiling now... By the way, when build will end, deb for KDE 3.0.4 for sid will be apt-gettable from deb http://zigzag.lvk.cs.msu.su/debian sid/ Sources in debian format alreaddy are at deb-src http://zigzag.lvk.cs.msu.su/debian source/ As for cdbakeoven, it wants to mount cdrom to temporary directory, and author recommenrs to run cdbakeoven as root to make that possible ... gcombust and xcdroast from sid seem to work. But they don't have KDE interface. And, of course, you've got to be a member of group cdrom. What is the Debain way to allow ALL users to use cd recorder? I won't remember to add all new users to cdrom and floppy groups, so I just set device permissions to 666. But sometimes permissions are reset for some reason ... Why?

koncd or other cd burning software for KDE 3.0.x
Hi, I recently installed unofficial KDE 3.0.2. I found out later that there is no CD burning software anymore. I used to use kreatecd but that has, as I understand it, been replaced by koncd for KDE 3.0.x. Koncd is part of the official kde-multimedia sources but there is no koncd .deb. Is there any particular reason why it is not in the unofficial .debs? Yours, Gerrit Jan. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble?
