■ Probes can be used to test for server or firewall connectivity and proper operation.
■ Probes can be defined to simulate requests for these protocols:
■ ICMP: Sends ICMP echo (ping) requests to a real server.
■ HTTP: Sends HTTP requests to a real server, using TCP port 80.
■ WSP: Requests and verifies the replies using Wireless Access Protocol (WAP),
port 9201.
■ Telnet: Opens and closes a Telnet connection (TCP port 23) to a real server.
■ TCP: Establishes and resets TCP connections to a real server. This can be used
to support any TCP port, including HTTPS or SSL, port 443.
