FTP only shell

This shell only allows ftp access, an alert message is sent if an interactive login is attempted. This needs adding to /etc/shells to be a valid shell.

#!/bin/bash

#Written by Andrew Stringer ages ago.
#Use this script as a login shell for users where you don't want shell access,
#ie. ftp only users on a webserver.
#You will probably have to add this to the /etc/shells file to have the system use it.

TERM=vt100
export TERM

#Set this to point to where policy queries should be sent.
ADMIN=sean.mcgivern@igt.com
#Set this to the alert recipient.
MAILTO=ww-noc@igt.com

#This may have to be modified to suit how your system defines itself.
