Hello, my system BIOS support booting from iSCSI. I set up readonly target with no authentication: targetcli shell version 2.1.fb49 grub .................................................................. [/scratch/ISO/GRUB (1.8MiB) write-back activated] | | o- alua ................................................................................................. [ALUA Groups: 1] | | o- default_tg_pt_gp ..................................................................... [ALUA state: Active/optimized] | | o- tpg1 ................................................................................................ [gen-acls, no-auth] | | | o- mapped_lun0 ............................................................................... [lun0 fileio/grub (rw)] The readonly flag does not seem to be honored ^^^ Anyway, the initiator cannot log in: 3,1360,2329588663878,-;Initiator sent zero length security payload, login failed 3,1361,2329588663897,-;iSCSI Login negotiation failed. How can I export a LUN without a password? Thanks Michal
