Hello fpc-pascal,

I want to make a program in Free Pascal (Linux) that does the same as the Linux "ping" command (pinging a host and measure the time it takes, if the host is reached).

Somebody already made a program like that? Or maybe where I can find some information about how it works?

I took a look at a C source for a ping program, but it's a bit difficult to understand how it works using that source, because many different options are implemented.

traceroute would be interesting as well, but ping is the one i really need now.

many thanks in advance,
Udo
