open-iscsi 2.0.873-3ubuntu11 (amd64 binary) in ubuntu vivid

 Open-iSCSI is a high-performance, transport independent, multi-platform
 implementation of RFC3720 iSCSI
 .
 Open-iSCSI is partitioned into user and kernel parts where the kernel
 portion implements iSCSI data path (i.e. iSCSI Read and iSCSI Write)
 The userspace contains the entire control plane consisting of:
  * Configuration Manager
  * iSCSI Discovery, Login and Logout processing
  * Connection level error processing
  * Nop-In and Nop-Out handling
  * Text processing, iSNS, SLP, Radius et cetera (future)
 .
 The userspace component consists of a daemon, iscsid and a management
 utility, iscsiadm
