Telnet KnockKnock Server (version-1.0)
------------------------------------------------------
Developer: Shubham Darlinge (shubh.darlinge@gmail.com)
Project base language: JAVA

## Requirements:
	* A machine that could act as a server machine for deploying server
application.
	* Java (JRE - www.java.com)
	* JDK (for compiling only)

## Compilation:

	This project was built in NetBeans on jdk-1.8.0_45. To compile it, 
import the telnet-knock-knock-server-netbeans.zip file into NetBeans and press 
F6, or, extract all the contents from src.zip into a folder and using the folder 
as base directory, compile the file "TelnetKnockKnockServer.java" using javac 
binary in the JDK.

## Deploying the server:

	Compile the source in to binaries or use the provided bin.zip for 
running the TelnetKnockKnockServer.class file using following command:
	> java TelnetKnockKnockServer
to run the serven in default configuration. It does not show/log any information 
in the default mode. The default server port is 23. The complete modes of 
operation and usage information is as shown below:

Telnet KnockKnock Server (version-1.0)

Usage:
  java TelnetKnockKnockServer	[-p | --port PORT_NUMBER] 
				[-l | --log [-f | --logfile LOG_FILE_NAME]] 
				[-o | --output] 
				[-? | --help]

  -p, --port	Specify the port number (default is 23)
  -o, --output	Output information on screen
  -l, --log	Output information to log file
  -f, --logfile	Specify the log file name (default is telnet-log.log)
  -?, --help	Display this help message

	Using this command the server application can be deployed on a server 
machine and can be accessed from over the internet.

## Accessing the server using a Telnet client:

	Using telnet clients available on almost every operating system, the 
server can be accessed and used. For example, to access the server running on a 
machine having an arbitary ip address xx.xx.xx.xx, this server can be a accessed 
from a Windows platform using the command:
	> telnet xx.xx.xx.xx
if the server is running on default port 23. If the port is explicitly specified 
while executing server (say 3999), then the command is modified as:
	> telnet xx.xx.xx.xx 3999

## Testing the server locally:

	You can test it in the a local network as follows:
  1. Keep two machines connected in a local area network. (Let ip address of 
machine #1, the server machine, to be 192.168.1.1)
  2. Run the server in machine #1 using following command:
	> java TelnetKnockKnockServer -o -l
  3. Open up a terminal or command prompt on machine #2.
  4. Type and run the following command:
	> telnet 192.168.1.1
  5. Respond to the server from the client and connecting will be automatically 
closed at the end of conversation.

## Notes
	* Some operating systems may block this command from executing 
because of permission issues. In such case, make sure that the operating system 
allows this application to use the port 23 by providing administrative 
privileges or specify another port using -p (e.g. -p 3999). While using another 
port (say 3999), the command in step 2 is modified as:
	> java TelnetKnockKnockServer -o -l -p 3999
and that in step 4 is modified as:
	> telnet 192.168.1.1 3999
	
	* If another machine is not available, the server can be accessed from 
same machine and another terminal or command prompt by modifying command in 
step 4 as:
	> telnet 127.0.0.1
	or
	> telnet 127.0.0.1 3999

	* While running the server, make sure that the "knock-knock-jokes" file 
is placed in the base directory as it uses the file as jokes database. Another 
option is to explicitly specify the file directory and name using the -f or 
--logfile switch.
