Either AutoPPP
or
Make a script as the users shell
(if you want to allow ftp access add the script path to /etc/shells)
here's a little script you can tweak to suit your server and paths
the second time they login all they get is a passwd prompt
#!/bin/bash -login
numlogins=`/usr/bin/who | /usr/bin/egrep -w "$LOGNAME" | /usr/bin/wc -l`
case $numlogins in
*"0"*|*"1"*) exec /etc/ppp/ppp.sh
;;
*"1"*|*"2"*)
echo "Hello $LOGNAME"
echo "New security measures mean that shell access,"
echo "is no longer available. If you have a problem"
echo "with this then please talk to Brendan"
echo ""
echo " As you are already logged in"
echo " You can now change your password. "
echo ""
echo " If you DONT want to do this"
echo " just hit the [ Enter ] key "
echo
exec /bin/passwd
logout

*) /etc/ppp/dupealert.sh
