iscsi源代码 UNH的progect 有initiator端和target端的源码

#!/bin/sh
#
# Sample setup script that loads a 
# target driver and initiator on the same machine.
#
# Note that the target is **generally **
# built as a Memory RAM device that will appear
# as a /dev/sdX where X is the next available
# SCSI unit on the next HBA. It reads nothing
# and writes to nowhere ( however data transfer
# does occur ). 
#
# You can use FILE I/O or direct SCSI I/O
# by changing the defines in 
# /opt/unh/iscsi/src/target/scsi_target.h
#
# See the README in the src/target directory for
# slightly more detail.
#
# If this scripts succeeds , Check /var/log/messages
# for the new device names :
# 
#  Attached scsi disk sda at scsi0, channel 0, id 0
#
# fdisk /dev/sda 
#
# You can at least do I/O using dd if=/dev/sda of=/dev/null
#

# this starts a init/target setup on a local loopback
