Inter server port monitoring

Hi Team,

Plugin will helps you to monitor whether given port is listening between the Server A and Server B or not.
i.e from Server C you can check port listened between Server A to Server B.

Achieved the same by writing two lines of simple code.
Works simple and efficient.

Attached file and steps for same (to newbies like me )

Steps:
*************************
Step 1 : Place the file in the below mentioned path of client server(SERVER_A).
/usr/local/nagios/libexec
Note : Please make sure the file has nagios user to execute permission.

Step 2 : Please append the below command in the respective config file.

File path : /usr/local/nagios/etc/nrpe/common.cfg

command[check_net]=/usr/local/nagios/libexec/check_net.sh $ARG1$

Step 3 : Now check from nagios server by following command.

/usr/local/nagios/libexec/check_nrpe -h SERVER_A -c check_net -p PORT_NUMBER -d SERVER_B

***************************
Thanks in advance.
