intercept the ip address of a telnet session
The situation:
a Unix system (UnixWare 7.1.3) to which are connected other systems;
various p.c. on the LAN that they connect Unix to the system via TelNet.
The problem:
I need to intercept the address IP of the p.cs. connected via telnet to the Unix system.
Particularly, I have to know the address of the specific p.c., immediately after it has completed the login so that to be able to redirect some elaborations on its shared resources.
This use, obviously, has to be already operating in the shell, immediately after having made login.
I have tried to see between the various commands and file of system, but I have not succeeded in understanding as the system it associates a host to its ip address.
With the command "netstat - n - p tcp" I succeed at the most in knowing what systems are conversing by tcp-ip, but the problem is that this command not me from specific information for the p.c. from which I am performing the session telnet.

Situazione:

vari p.c. in rete locale che si collegano al sistema Unix via TelNet.
Problema:
ho bisogno di intercettare l'indirizzo IP dei p.c. che si collegano al sistema Unix.
In particolare, devo conoscere l'indirizzo del p.c. specifico, subito dopo che ha completato il login, in modo da poter reindirizzare alcune elaborazioni sulle sue risorse condivise.
Questo utilizzo, ovviamente, deve essere funzionante già nella shell, subito dopo aver fatto login.
Ho provato a vedere tra i vari comandi e file di sistema, ma non sono riuscito a capire come il sistema associa un host al suo indirizzo ip.
Con il comando "netstat -n -p tcp" riesco al massimo a sapere quali sistemi stanno dialogando in tcp-ip, ma il problema è che questo comando non mi da informazioni specifiche per il p.c. da cui sto eseguendo la sessione telnet.

xorpsh
xorp(1) General Commands Manual xorp(1) NAME
xorpsh -- XORP Command Shell SYNOPSIS
xorpsh [-c command] [-t directory] [-e] [-h] [-v] DESCRIPTION
This manual page documents briefly the xorpsh command. This manual page was written for the Debian distribution because the original program does not have a manual page. xorpsh is the command used to interact with a eXtensible Open Router Platform (XORP) router. This command starts up a command line inter- face (CLI), that allows the configuration of the router and monitoring of the router state. The xorpsh command provides an interactive command shell to a XORP user, similar in many ways to the role played by a Unix shell. In a production router xorpsh might be set up as an user's login shell - they would login to the router via ssh and be directly in the xorpsh. It can also be run directly from the Unix command line. xorpsh should normally be run as a regular user; it is neither necessary or desirable to run it as root. If an user is to be permitted to make changes to the running router configuration, that user needs to be in the Unix group xorp. The Debian package installation automatically sets up both a xorp user and a xorp group to which this user belongs. However, any user can run the xorpsh command unless locally restricted by the administrator. OPTIONS
xorpsh allows the following options: -h Show summary of options. -v Print verbose information. -c command Specify command(s) to execute. -t directory Specify templates directory. -e Exit immediately if cannot connect to the rtrmgr SEE ALSO
xorp_rtrmgr (8) This program is documented fully in the Xorp User Manual, chapter Command Structure, available at /usr/share/doc/xorp-doc/ in Debian sys- tems when the xorp-doc package is installed. AUTHOR
