iSCSI No portals found Debian

Hi -

I've been banging my head into a wall trying to figure this out. I'm setting up an iSCSI share on Debian, but keep getting "No portals found" on my client machine when I do: iscsiadm -m discovery -t st -p 192.168.3.21

In my google searches, I keep running into ACL solutions, but my ACL is set to "ALL". I've reinstalled my target and open-iscsi but nothing helps. I can ping my target from the client without any problems, and have put my initiator name into the initiators.conf file on the client. Any solutions will be greatly appreciated!

sudo tgtadm --mode target --op show

When I worked on this I was doing everything through configfs. See http://linux-iscsi.org/wiki/ConfigFS Things may have changed since then but to me it looks like you have the SCSI device created but not the network side. See what you get from:

Code:

cat /sys/kernel/config/targetiscsi/<YOUR IQN>/<YOUR TARGET>/enable
cat /sys/kernel/config/targetiscsi/<YOUR IQN>/<YOUR TARGET>/attrib/authentication
ls /sys/kernel/config/targetiscsi/<YOUR IQN>/<YOUR TARGET>/np

Edit: Checking my old notes, to do this you may need:

Code:

modprobe configfs
mount -t configfs none /sys/kernel/config
