Telnet client IP determination
I have configured my firewall to allow only five remote IP's to connect to my server. Upon connection...i would like to automate the Xsession functions for authorized IP's.
Mainly, $DISPLAY of the environment to the client.
I understand that the "gethostbyaddr" function is capable of this. But this means i would have to make another connection(as in...a separate client-to-server) other than the original telnet to perform this. Correct?
How do i do this without burdening the client with starting two scripts?

tcp-env
tcp-env(1) General Commands Manual tcp-env(1)
NAME
tcp-env - set up TCP-related environment variables
SYNOPSIS
tcp-env [ -rR ] [ -ttimeout ] program [ arg ... ]
DESCRIPTION
The input for tcp-env must be a TCP connection. tcp-env finds out information about that connection, puts the information into several
environment variables as described in tcp-environ(5), and runs program with the given arguments.
Usually tcp-env is run from inetd. It might instead be run from another server that already sets up the right environment variables; if
PROTO is set to TCP when tcp-env is invoked, tcp-env assumes that all the other variables are set up properly, and it does not check
whether the input is a TCP connection.
OPTIONS
-r (Default.) Attempt to obtain TCPREMOTEINFO from the remote host.
-R Do not attempt to obtain TCPREMOTEINFO from the remote host.
-ttimeout
Give up on the TCPREMOTEINFO connection attempt after timeout seconds. Default: 30.
