I have desktop with DVD-RW drive that runs primarily on Linux (namely Ubuntu 9.10). My wife has netbook that rins Windows XP with no cd/dvd drive. There’s also LAN through our ADSL modem/router. I’ve “ported” (actually, I’ve just grabbed sources and ran
iscsitarget package from Ubuntu Lucid to Karmic (here are packages), installed it (
sudo aptitude install iscsitarget; sudo m-a a-i iscsitarget) and configured it in the following way (
Target iqn.2020-01.local.develop7-desktop:storage.disc.dvdrw Lun 0 Path=/dev/sr0,Type=blockio #I've skipped commented lines
Also, I’ve opened port 3260 with
$ sudo ufw status | grep 3260 3260 ALLOW 192.168.1.0/24
But (here’s the trouble) I still can’t connect to this target from Windows box. Microsoft Software iSCSI Initiator screams “Logon failure” upon connect attempt, and, respectively, fails to connect. After unsuccessful connection attempt I’ve noticed this line in
dmesg | tail‘s output:
iscsi_trgt: ioctl(299) invalid ioctl cmd c078690d
So the question is — what’s wrong with my config/iSCSI target/whatever else? Or, in short — what I’m doing wrong?
Thanks in advance.
This Nabble thread indicates this could be a consequence of an old IET kernel module included in Ubuntu’s kernel. Check the thread closely and see if your symptoms align. This might make sense, since there seems to be a huge difference in versions between Karmic’s official iscsitarget package and the version you’re attempting to backport.
If so, the fix seems to be to find and disable the old module:
the original kernel module on Ubuntu is at:
/lib/modules/$(uname -r)/kernel/ubuntu/iscsitarget/iscsi_trgt.ko, and it’s necessary
depmod -ato regenerate modules.dep before attempting to load the new module,
mv /lib/modules/$(uname -r)/kernel/ubuntu/iscsitarget/iscsi_trgt.ko /lib/modules/$(uname -r)/kernel/ubuntu/iscsitarget/iscsi_trgt.ko.orig depmod -a
