Windows dynamic libraries, calling conventions, and transmute
Making our own ping: Part 2
So, how does
ping.exeactually send a ping? It seems unrealistic that
ping.exeitself implements all the protocols involved in sending a ping. So it must be calling some sort of...
FFI-safe types in Rust, newtypes and MaybeUninit
Making our own ping: Part 3
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
IcmpSendEcho2Ex. But for our...
A simple ping library, parsing strings into IPv4 address
Making our own ping: Part 5
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....
The builder pattern, and a macro that keeps FFI code DRY
Making our own ping: Part 6
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();...
Finding the default network interface through WMI
Making our own ping: Part 7
Let’s set aside our
supproject for a while.
Don’t get me wrong - it’s a perfectly fine project, and, were we simply rewriting “ping” for Windows...
Parsing IPv4 packets, including numbers smaller than bytes
Making our own ping: Part 11
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?
Parsing and serializing ICMP packets with cookie-factory.
Making our own ping: Part 12
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...
Crafting ICMP-bearing IPv4 packets with the help of bitvec
Making our own ping: Part 14
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...
