Are there any reviews of CryPing

If you google you can find reviews of CryPing.

Can you ping a port?

With CryPing you can ping a port. The flag "-p port-number" allows you to ping the specified port number. So:

This shows an attempt to ping the TCP/IP port 119. In this example the ping is failing and is this is because the www.cryer.co.uk site does not run an NNTP server - NNTP being the service which might typically be listening on port 119.

You can also use the flag "-port port-number", which is slightly easier to remember but otherwise is the same as "-p port-number".

Be aware that you can only ping TCP/IP ports, not UDP ones.

What is the difference between "-p 80" and "-http"?

The flag "-p 80" tells CryPing to ping port 80, which is the port used for HTTP requests. The flag "-http" tells CryPing to ping using HTTP. Both use the same port, but the behaviour is different.

The flag "-p 80" tells CryPing to simply check whether a connection can be made to port 80 and how long it takes to complete the connection, e.g.:

This shows whether something is listening on port 80, but without any requirement as to what is listening on that port.

The flag "-http" tells CryPing to check whether it can connect to the HTTP server, and how long it takes to complete the connection, e.g.:

So in this case it is testing that what is listening on port 80 does appear to be a web/HTTP server.

So, in summary "-p 80" checks whether something is listening on port 80 but it does not matter what is listening, whereas "-http" (which also connects to port 80") checks that there is an HTTP server listening.
