TesterNet network monitor, TCP monitor and Web server monitor can verify that your servers are alive and working well. You can monitor URLs, ping any server or establish TCP connections with them (FTP, SMTP, POP3, Telnet, and any other). If your server cannot be reached after a number of times, it will notify you by a message popup or by e-mail. You can review the history of network events in the event list. You can debug what internal communications are being made by your computer with the IP Debug, and see the internal packets that your computer receives and send. You can scan for open ports in your network with the Port Scanner.
