# This expects that the iSCSI server being tested is at $TARGETIP and exports
# two targets: $TARGET1 and $TARGET2; the former requiring no authentication,
# and the latter using CHAP with user $USER and secret $SECRET.  Discovery
# must be permitted without authentication.  Each target must contain exactly
# two LUNs, 4GB each.  For example, ctl.conf(5) should look like this:
# 
# auth-group meh {
# 	chap user secretsecret
# }
# 
# portal-group meh {
# 	listen 0.0.0.0
# 	discovery-auth-group no-authentication
# }
# 
# target iqn.2012-06.com.example:1 {
# 	auth-group no-authentication
# 	portal-group meh
# 	lun 0 {
# 		path /var/tmp/example_t1l0
# 		size 4G
# 	}
# 	lun 1 {
# 		path /var/tmp/example_t1l1
# 		size 4G
# 	}
# }
# 
# target iqn.2012-06.com.example:2 {
# 	auth-group meh
# 	portal-group meh
# 	lun 0 {
# 		path /var/tmp/example_t2l0
# 		size 4G
# 	}
# 	lun 1 {
# 		path /var/tmp/example_t2l1
# 		size 4G
# 	}
# }
# 
# Remember to create the backing files (/var/tmp/example_t1l0 etcc)
#
# On the initiator, $MNTDIR will be used for testing.
