Thank you radoulov for your help on netcat command (nc -lp)
Hello,

Thank you very much for the line nc -lp <port> . I tried to run simple chat session with nc as it's shown in catonmatDOTorg but failed miserably with that syntax inspite of opening port 7777 by iptables . But your command example is working nicely.
So a bagful of thanks Smilie)

Only one hitch. After opening a port [7777 using iptables such as iptables -A INPUT -m state --state NEW -m tcp \
-p tcp --dport 7777 --j ACCEPT ] nmap still showing the port
7777 is closed. [nmap -p 7777 localhost]

Oh! I have made a conceptual mistake. I have unblocked a port but haven't opened it as unblocking a port doesn't mean opening the port, I have just enable the port to reach for so a service can use it, When a service is running in that port,, then the port is said to be a open port[ listening for a connection]

Net::Hotline::PrivateChat(3pm)				User Contributed Perl Documentation			    Net::Hotline::PrivateChat(3pm)

NAME

       Net::Hotline::PrivateChat - Private chat object used internally by Net::Hotline::Client

SYNOPSIS

	   use Net::Hotline::PrivateChat;

	   $pchat = new Net::Hotline::PrivateChat;

	   $pchat->subject("Issue 1: Monkey beards");
	   $pchat->reference(0x313337);
	   ...

DESCRIPTION

       Net::Hotline::PrivateChat is a simple class for storing and retrieving private chat information,  You should never have to create your own
       Net::Hotline::PrivateChat objects when using Net::Hotline::Client.  Getting and (to a lesser extent) setting attributes is all that should
       be necessary.

CONSTRUCTION

       new REF, USERLIST, SUBJECT
	   Creates a new Net::Hotline::PrivateChat object with the reference REF, userlist USERLIST, and subject SUBJECT, where REF is a number,
	   USERLIST is a reference to a hash of Net::Hotline::User objects keyed by socket number, and SUBJECT is a string.  Any missing arguments
	   will be set to undef.

METHODS

       All the Net::Hotline::PrivateChat methods are simple attribute get/set routines. If given an argument, they set an attribute.  In all
       cases, they return the current value of the attribute.

       reference NUM
	   The private chat reference number.

       subject TEXT
	   The subject of the private chat.

       userlist HASHREF
	   The list of users in the private chat.
