FRS7556

During the recent upgrade of h1dmtlogin from Deb7 to Deb8 we lost the service which sends sysadmin an email when someone successfully ssh logs into the machine. Turning on this service was easy, most of the parts were already in place and it just needed a single line addition to the pam.d/sshd file. This service is now working, and I took the opportunity to document the install in the cdswiki.
