|
||||
|
||||
This is a starting point for Rust solutions to the
|
||||
["Build Your Own DNS server" Challenge](https://app.codecrafters.io/courses/dns-server/overview).
|
||||
|
||||
In this challenge, you'll build a DNS server that's capable of parsing and
|
||||
creating DNS packets, responding to DNS queries, handling various record types
|
||||
and doing recursive resolve. Along the way we'll learn about the DNS protocol,
|
||||
DNS packet format, root servers, authoritative servers, forwarding servers,
|
||||
various record types (A, AAAA, CNAME, etc) and more.
|
||||
|
||||
**Note**: If you're viewing this repo on GitHub, head over to
|
||||
[codecrafters.io](https://codecrafters.io) to try the challenge.
|
||||
|
||||
# Passing the first stage
|
||||
|
||||
The entry point for your `your_server.sh` implementation is in `src/main.rs`.
|
||||
Study and uncomment the relevant code, and push your changes to pass the first
|
||||
stage:
|
||||
|
||||
```sh
|
||||
git add .
|
||||
git commit -m "pass 1st stage" # any msg
|
||||
git push origin master
|
||||
```
|
||||
|
||||
Time to move on to the next stage!
|
||||
|
||||
# Stage 2 & beyond
|
||||
|
||||
Note: This section is for stages 2 and beyond.
|
||||
|
||||
1. Ensure you have `cargo (1.70)` installed locally
|
||||
1. Run `./your_server.sh` to run your program, which is implemented in
|
||||
`src/main.rs`. This command compiles your Rust project, so it might be slow
|
||||
the first time you run it. Subsequent runs will be fast.
|
||||
1. Commit your changes and run `git push origin master` to submit your solution
|
||||
to CodeCrafters. Test output will be streamed to your terminal.
