Unix Tip #4039- March 3, 2012

KEEPING PEOPLE OUT


If you want to keep people
of your server, but want them
to access their pop mail on
the same box set up the following
line in the password file:

babba:rtnRkIgCy4l4T:830:10:Babba Booie:/home/babba:/bin/nologin


Then create a script called
/bin/nologin that contains:

#! /bin/sh
echo "Sorry, but your account is only allowed POP access to this host."
exit 1

when a person attempts to log into
their defined shell it will run
the /bin/noling script, display
the message, and exit them from
the system

Have Fun
