plz help me to solve this socekt progm..urgent...
MY client and server need to achieve the following requirements:
1.1. program for client needs to take two arguments that specify the name of server and the port that it is trying to connect to. Your program for server needs to take an argument that specifies the port that it is listening to.
2.2. server will start first and keep listening to the specified port. Your client will connect to the port that your server is listening to, and a socket between your client and server is constructed.
4.3. client will first prompt a welcome message that asks the user to enter a username using the keyboard. This username will then be sent to the server. Then, your server, after receiving the username from your client, will send an acknowledgment message to the client.
6.4. client, after receiving the acknowledgment message from your server, will prompt a message that asks the user to enter the corresponding password. This password will then be sent to the server. Then, your server, after receiving the password from your client, will verify the received pair of username and password against the list of legitimate pairs. If the result is positive, the server will send a success message to the client. If the result is negative, the server will send a failure message to the client.
8.5. client, after receiving the result message, will print out the result and close the socket. Your server will close the socket following the client, and keep listening for the next client request.

efax-gtk-socket-client
efax-gtk-socket-client(1) General Commands Manual efax-gtk-socket-client(1)
NAME
efax-gtk-socket-client - a client of efax-gtk to work with lpd/lprng
SYNOPSIS
efax-gtk-socket-client [hostname] [port]
DESCRIPTION
This program enables lpd/lprng to access the efax-gtk socket server. Meaning the user can send faxes to a printer, which will ack as a fax.
It takes two arguments - first a hostname to connect to, and secondly a port number at that hostname to connect to. All efax-gtk-socket-
client does is to read from standard input (in this case from lpd/lprng) and passes it to a socket at the hostname and port number passed
as arguments to it (namely the hostname of the computer efax-gtk is running on - normally you would specify localhost - and the port number
of the socket).
fax:
:sd=/var/spool/fax:
:mx#0:
:sh:
:lp=/dev/null:
:if=/var/spool/fax/efax-gtk-faxfilter:
This will cause a printer by the name of "fax" to be available, which (if printed to) will send the file to the efax-gtk socket server. If
you set efax-gtk to listen on a port other than port 9900, you will need to amend the file /var/spool/fax/efax-gtk-faxfilter by hand to
specify the correct port number on which efax-gtk is listening.
Don't forget to restart the lpd printer daemon after amending /etc/printcap.
OPTIONS
[ hostname ] - The name of the host to listen to. Usually should be locahlhost.
[ port ] - the port number to listen to on the [ hostname ].
