Probably I didn't make myself clear here: I just found out that making cdrecord suid root does infact work. 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. This is between the machines in question: andree@aurich:~/downloads/kernel>scp linux-2.2.17.tar.bz2 jever: Password: linux-2.2.17.tar.bz2 100% |************************************************| 13727 KB 00:02 Between 2 and 3 seconds for 13+MB should be sufficient for CD writing don't you think. 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?

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/bin>ldd 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/bin>ldd 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.
