You didn;t write where is the problemastic part.<br />
I think a simple two question program should work. First interogathe the user as to the machine name and later for the service name.<br />
If you plan to offer only known in advance services that sit at specified ports you may simply encode the info as an array (associative or not is up to you).<br />
Other-wise if the services are known services that sit at well known ports simply parse /etc/services for port number.<br />

I want to write a program that provides services to it users such that:<br />
1. The user inputs a known servername and service e.g time, daytime, whois, etc.<br />
2. The program then interrogates the named server and requests for the service required by the user.<br />
3. The server's output is then displayed on the user's display in an easy to read format.
