SocketTest - powerful and small software tool for socket testing. It can create both TCP and UDP client or server. It can be used to test any server or client that uses TCP or UDP protocol to communicate.
Had downloaded the sockettest and also jre 1.3.0 but unable to install, kindly provide the steps .
Would be nice if it worked on Unix hosts.
It will be good, if I can select any size file to send instead of just message and feature can be extended to get upload and download speed at both server and client side for both TCP and UDP.
