+AD4 I am exporting a LUN with a general purpose filesystem (non cluster

+AD4 mount it.

+AD4 At the moment, I protected the iSCSI LUN with both an IP-based access
+AD4 list and a username/password combo, but hard limiting the maximum number
+AD4 of connections opened against it to 1 (one) would be a nice thing...

+AD4 working well, they are somewhat harder to setup.
Hi Danti,
As far as I know this is not yet supported by the SCSI target code. I think
the kernel code will have to be modified to add this functionality.
Bart.
