Check out man privileges on Solaris for more information on what makes a ready to use system in this area. I'm discussing the shortcomings of cdrecord under Linux. Once Linux implements a user ready version of the current experimental interface, it would make sense to let cdrtools use this interface. The capability library has been around for years.

You are again uninformed: The security issue was: sending of SCSI commands was possible on file descriptors opened with O_RDONLY. The correct fix for this security bug was to require O_RDWR instead of O_RDONLY. That is like saying that I have to open a file for read and write just to read it. Most people don't think allowing general write permission of raw devices is a correct fix. The correct fix was to allow a program to write SCSI commands (such as seek and read) with O_READ, but not to let other commands through. And it did take some time to get the list of allowed commands correct for the general case. And there are cases where odd vendor commands are blocked to non-root. Agreed it's not perfect, but it does keep people from reconfiguring the firmware when given read access. This did not harm interfaces but cure the problem. The problem was that Mr. Torvalds did introduce an incompatible interface change instead although many people on LKML did send their protest mails. Given a choice of more security or more convenience, I choose security. I don't insult people who make other choices, their priorities may be different from mine.

Hi, I tried cdrecord -scanbus. But I got the following error message. cdrecord: No such file or directory. Cannot open SCSI driver. Can you help me please? Looks like you stirred up other much older quarrels. These quarrels are the reason why we got some wealth of cdrecord compatible programs. Better too many than too few.

It didn't orginally for me but that was apparently due to a different problem. So, I'm a happy camper with regards to this. o How can I use rscsi without having to have rshd running on the server=20 machine? Impossible o Is there a way to use ssh instead of rsh? Why? ssh is way too slow for cd writing. Hm...I think it depends.

Or is there a hidden latency problem somewhere? A good reason to use ssh/sshd would be encryption of the datastream in situations where you want to use it across a non-trusted net. If you have a ssh aware rcmd(3) implementation it should work. I'll check that out, thanks! Would that give me encryption of the data? I fear not, as rcmd is rcmd and doesn't come with encryption... Other questions: What is your opinion on http://sourceforge.net/projects/linux-iscsi? I understand that this is only a client to access iSCSI services. Are you aware of any server iSCSI development for Linux? This would pretty much be what rscsi is doing, wouldn't it? The RSCSI idea is more than 5 years old and has been finally implemented short before the ISCSI idea came up. If you believe that ISCSI makes sense, write a ISCSI transport implementaion for libscg and send it to me... I'm using SANE to access a remote scanner just as I'm trying to access a remote CD writer via cdrecord/rscsi. This prompts me to ask the question whether you've ever contemplated to turn cdrecord into a library just like the SANE folks did? Sorry, I contacted the SANE people many times to use my scsi trnaport implementaion. They don't like it because their implementation is so InSANE that it is not possible to integrate a SCSI trabsport with a clean interface :-( That is quite sad to hear as it sounds like triplication of effort. My understanding is that iSCSI is an open (?) industry standard which can be implemented by anyone. (Well, anyone that understands the matter, ie. not me, so don't hold your breath... ;-) ) This to my mind gives it an edge over rscsi and whatever SANE is doing. I quite like the SANE approach as it doesn't require me to run rshd but comes with its own custom-purpose daemon. This is purely from a user perspective without any insight in the actual implementation of course. What I really meant with my library question is this: In the SANE world you have e.g. aurich:/usr/binldd xsane libsane.so.1 = /usr/lib/libsane.so.1 (0x40014000) In other words, the functionality is encapsulated in a library. Wouldn't it be nice to have something like: aurich:/usr/binldd gtoaster libcdrecord.so.1 = /usr/lib/libcdrecord.so.1 (0x40014000) I'd dare say that making the cdrecord functionality available as a library should have a number of advantages over calling a separate program.

Hi Jörg Make sure that .rhost is set up correctly. The permissions of ~rscsi/.rhosts were a bit, er, liberal. It works now, as root I can do cdrecord dev=REMOTE:[EMAIL PROTECTED] -scanbus on the client machine and I get a list of SCSI targets on the server machine. READ the README's for remote SCSI! What do you mean? How do you think did I get as far as I did before contacting the mailing list? ;-) Seriously, I tried to do the preferred method from README.rscsi.gz as a starting point. Are there other READMEs for remote SCSI?
