So, how does ping.exe actually send a ping? It seems unrealistic that ping.exe itself implements all the protocols involved in sending a ping. So it must be calling some sort of...

It’s time to make sup, our own take on ping, use the Win32 APIs to send an ICMP echo. Earlier we discovered that Windows’s ping.exe used IcmpSendEcho2Ex. But for our...

We’ve just spent a lot of time abstracting over LoadLibrary, but we still have all the gory details of the Win32 ICMP API straight in our main.rs file! That won’t do....

Our ping API is simple, but it’s also very limited:

pub fn ping(dest: ipv4::Addr) -> Result<(), String>

// called as:
ping(ipv4::Addr([8, 8, 8, 8])).unwrap();...

Let’s set aside our sup project for a while.

Don’t get me wrong - it’s a perfectly fine project, and, were we simply rewriting “ping” for Windows...

Hello and welcome to Part 11 of this series, wherein we finally use some of the code I prototyped way back when I was planning this series.

Where are we standing?

Let’s...

In the last part, we’ve finally parsed some IPv4 packets. We even found a way to filter only IPv4 packets that contain ICMP packets.

There’s one thing we...

So. Serializing IPv4 packets. Easy? Well, not exactly.

IPv4 was annoying to parse, because we had 3-bit integers, and 13-bit integers, and who knows what else. Serializing it is...
