TCP Port Monitor - TCP Port Monitors Using Telnet
Port Monitor - The Mechanism
TCP port monitoring is one of options developed by Dotcom-Monitor® which allows you to check Internet services in one more way. How does port monitor works? Our agents from all over the world will try to connect to the server specified on the specified port and see if the remote computer accepts connections on this port.
If the connection is not accepted the service is probably down and the notification process will start. Dotcom-Monitor® realize TCP port monitoring using telnet.
TCP Port in Networking
TCP Port Monitoring Configuration
In computer networking, a port is identified by
number system resource allocated to an
application running on a host network, to
communicate with applications running on other
network hosts (including with other applications
on the same host).
In a typical client-server model application is
waiting for the incoming data (or the connection
request, "Listening TCP port"; the role of server), or sends data (or the connection request) to the known TCP port, opened by the application server (client role).
