TCP and UDP ports test

[Maumuabr]

Dear folks my first post here... :-P

Im writing an script that have to test some TCP and UDP ports.

Im not an expert in this topic so i need some help on writing it :-D

For example:

I have hostA where the script will be executed.

HostB our app manager

So i wanna test if the connectivity between both are ok by the port 9990 TCP

$AMS_CONNECT=TCPConnect($AMS_IP,$AMS_PORT)

And for UDP 4104

$AMS_UDP_CONNECT = UDPOpen( $AMS_IP, $AMS_UDP_PORT)

Well.. my question is... if i use the premade functions UDPOpen and TCPConnect are the best way to do this? Or do u know any SO Tools that do this job well?

Pls send me your comments...

Thank you very much for helping..
