Configuring iSCSI on Linux

The Internet Small Computer Systems Interface (iSCSI) allows SCSI commands to be transmitted over a network. This allows block devices to be shared with remote machines as if they were local drives. In this lab, you will be tasked with configuring both the iSCSI target (server), and iSCSI initiator (client), in order to share block devices over a local network.
