iSCSI Enterprise Target

In the presence of conflicting information (lots of it) this is how I got iSCSI Enterprise Target running on Ubuntu 16.04 (LTS). First, install the required software with
sudo apt-get install iscsitarget
man ietd indicates that the configuration file is located at /etc/ietd.conf but it isn't, so instead:
sudo nano /etc/iet/ietd.conf
If you're following the "Creating an Open Source SAN" chapter of "Pro Ubuntu Server Administration" by Sander van Vugt, be careful when adding your target not to include a space between the comma and the type
    Lun 0 Path=/dev/sdb,Type=fileio
    Lun 1 Path=/dev/sdc, Type=fileio
One step that's missing from this chapter is to enable it (why isn't it enabled?).
sudo nano /etc/default/iscsitarget
Ensure this line is present in the configuration
Then exit nano, saving changes, and restart the iscsitarget service
sudo /etc/init.d/iscsitarget restart
If everything has gone to plan, you should be able to see these files
cat /proc/net/iet/session
cat /proc/net/iet/volume
Otherwise, have a look at the log
tail /var /log/syslog
