Cdrecord works perfectly without root if you are on Solaris but Solaris offers a _complete_ fine grained privileges implementation that Linux is still missing. see "man privileges" Before Linux-2.6.8.1, *) you could in theory write CDs/DVDs without root privileges is you did not care about coasters that are a result of buffer underruns. With Linux-2.6.8.1 the Linux SCSI kernel interface has been broken by an inexperienced programmer that claimed to fix a security problem which has been introduced some time before _without_ breking the kernel interface ;-) Without root privileges, cdrecord is not able to send all needed SCSI commands on a recent Linux kernel. The fact that _some_ SCSI commands may still be send without root provileges and the fact that cdrecord tries to self adopt to the features of the drive, often confuses novice-programmers like the Debian package maintainers for cdrecord.don't believe these inexpecienced people. *) With early Linux-2.4.x versions this did only work if you did play with device node permissions and did give up the security of your installation. Decent kernel implementations would not allow this as it is a security risk.

I've debugged more than one of the numerous libscg bugs last year, which all were either in the categories "standing in your own way", "artificial barriers" and "assumptions not covered by any standard", and often, just rearranging the execution sequence or removing superfluous differences would fix issues. None of the fixes or debugging with detailed fix instructions I offered to Jörg made the code AFAICS, and his rants last year also scared people away who were originally set to fix one of the Linux rlimit regressions. (I suggested a workaround, Jörg was aware of it, but didn't take it for unknown reasons, he wouldn't say. As usual :-(). This however is incompatible with Jörg's behavior, he isn't actually interested in getting his software portable, but rather "invests" his time into flamewar and offenses -- as this thread demonstrated with the long anti-Linux pro-Solaris rant when he was asked about non-root BSD usage. -- Matthias Andree

Do you like a decent discussion or do you like to be one of the uninformed people who participate in the braindead FUD against cdrtools? If you have no clue on the background, you should listen to people like me who know what they are talking about You are listening to the wrong people. > Moreover, the hacked version of cdrecord which comes with Fedora works > without root, although it's a bit old. Read the text of my last mail and try to understand _why_ _some_ people might believe that cdrecord is able to work under _some_ _conditions_. I am not sure about what limited services growisofs provides. I did see enough logs from cdrecord that verify the fact that Linux does not allow cdrecord to work correctly under all conditions. This is because Linux does not allow all the SCSI commands cdrecord needs for it's work unless cdrecord runs with root privileges.

problems writing a large file to DVD+R Double Layer disk
Hi, [I sent this message several hours ago from another email address, but it has not appear yet, so I am trying again with a different e-mail address] I am trying to write a .ts file to a DVD+R Double Layer disk, so far without success. The file has a size of 4613734320. I issue the command: growisofs -Z /dev/sr1 -R -J pd where pd is where my files are. I get the message: mkisofs: Value too large for defined data type. File pd/ts is too large - ignoring and the file is not written. This is with growisofs version 7.0, and mkisofs 2.01.01a24 I updated my growisofs and mkisofs to these versions because those that came with my Linux (growisofs: version 5.17, mkisofs: 2.01a27) does not recognise the DVD+R DL media: linux:/home/kish # growisofs -Z /dev/sr1 -R -J pd :-( /dev/sr1: media is not recognized as recordable DVD: 2B My system configuration is: OS: SuSe Linux 9.1, with kernel 2.6.11.4 DVD Writer: LG GSA 5163D For now, I just want to write the file as a data file to the disk, so I am not worried about DVD compatibility. Thanks in advance for any help/information on how I can write the file to the disk! Cheers, Kish -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?

All vendor unique commands, such as for Yamaha/Plextor specific functions. All commands for old (pre-MMC) writers. Some MMC commands needed for DVD writing, but here I do not remember the commands.

This is with growisofs version 7.0, and mkisofs > 2.01.01a24 mkisofs currently only allows to write file with a max. size of 4 GB - 2k. In about 2 months, there will be a new version that supports files up to 8 TB. If you use Linux, you then will need to check whether the Linux kernel correctly supports multi-extent files. I will add the needed multi-extent file support to OpenSolaris at the same time > I updated my growisofs and mkisofs to these versions because those that came > with my Linux (growisofs: version 5.17, mkisofs: 2.01a27) does not recognise > the DVD+R DL media: > > linux:/home/kish # growisofs -Z /dev/sr1 -R -J pd > :-( /dev/sr1: media is not recognized as recordable DVD: 2B If you have problems with double layer disks, better use the cdrecord that comes with cdrtools-2.01.01a24. Note that you need to call cdrecord as root or install it suid root.
