Interesting?... Mmmh... May be bizarre :-P Now, i've reinstalled this PV745N with an unsupported, but hopefully less error prone with amanda, Fedora C. 5 If you're interested this appliance has W2003 Storage preinstalled and has no CD/DVD nor floppy drives. I tried an USB + http installation but failed (that usb thing seems utterly strange). I've installed that with PXE with not too much problem (hey, is very simple!, i thought it be tough http://www.stanford.edu/~alfw/PXE-Kickstart/PXE-Kickstart.html ) Thanks a lot list.

Well i have "fooled" amcheck into thinking he is uid 0 (changing /etc/passwd uid field for user Administrator) and no more setuid-root messages are shown (so, your getuid and server parts not patched related guess appears to be extremely true :-), but taper behaves (as expected) exactly the same way as it did: driver: FATAL reading result from taper: Software caused connection abort As stated below amtape and amlabel work fine, so IMHO this shouldn't be a permissions problem. ¿ There's some way to get a more verbose "why" from "taper" or "driver"? >BTW have you tried accessing your tape drive with other amanda and/or cygwin commands?

I do not use a real tapedrive/robot with amanda, and I doubt cygwin has the ability to access directly to the devices (there's no /dev fs anyway) >Can amtape and amlabel access your drive and changer script? Yep, I have used amlabel for label perfectly the virtual (on disk) tapes and amtape seems to work perfectly.

IIRC the closest thing to root was SYSTEM. Like unix' root, system has a fixed uid and gid. But it is not zero as in unix, instead I ISTR "18" for both. You have to create your "root" user to have this value and it "should" be mentioned in the amanda cygwin docs. The other thing I question is whether changes to the amanda code for cygwin has ever been extended to include the server pieces. The primary developer of those changes ?Doug Kingston?, was only intent on getting an amanda cygwin client, not a server. I do not recall seeing any reports of an amanda cygwin server. Some of the necessary changes could include the test for "root". If the code doesn't test for root by name, but instead by uid, then the numerical test is often something like: if ( getuid() != 0 ) error and as unix's root has a uid of 0, this can be simplified to: if ( getuid() ) error Both would fail if root == SYSTEM, ie uid 18. This is typical of changes needed for amanda cygwin clients and may not have been extended to the server code as that was not Doug's purpose.

Nope, AFAIK. The Windows equivalent is normally "Administrator" or in some special cases SYSTEM (this has ALL the powers posible).

I'm far from a Windows expert (I try to stay away from it as far as possible
:-), but on Cygwin you can run e.g. sshd on port 22 as an ordinary user.
So I guess amandad won't be a problem neither.
How the setuid tar wrapper should behave is a different question. I missed `cu'
on Cygwin so I compiled it myself, but it needed to be setuid too and according
to our sysadmin that feature didn't exist on Windows.
