Ping4 daemon example

Ping is a utility used to test the reachability of a host. Ping4 daemon example is a small application that answers the ping requests.

Running the application

The example is located in the examples/ping4d sub-directory. To run the application,

/examples/ping4d$ cargo run -- -f ping4d.toml

Explanation

Ping operates by sending an ICMP echo request packet to the target host and waiting for an ICMP echo reply. The pipeline uses the replace combinator to create a new reply packet for each received request packet. The request packet is immutable.
