is there an easy way to grab an user's ip upon login? i would like my servers to email page me when a user logs in ..but getting the IP and TTY is prooving more difficult then the date/time and username :) what i want is something like this
galactica: $USER logged in at `date` on $TTY from $IP SSH stores the IP($SSH_CLIENT) ..telent stores the ($REMOTEHOST) hostname..but 99% of my users telnet in from dialup and the rest rlogin from the PPP server(shell-only accnts) so what im lookin for i guess is a script that can look at wtmp/utmp and get the right info out of it ..i dont think doing a 'w' and grepping/awking it would work very well if the user is logged in multiple times.. eventually i would want to check the $IP variable and only email page me if it is an ip from outside our subnets. which is easy once i can get the ip in variable form. any ideas would be appreciated :) nate
