How can I write to a socket via curl? Need help with raw socket communication!

Hey everyone,

So, I’m trying to figure out how to write to a socket via curl. I’ve been messing around with raw socket communication, but I’m kinda stuck.

I know curl is usually for HTTP stuff, but I heard it can handle raw sockets too? Like, sending plain text or binary data directly.

Anyone got a quick example or tips on how to write to a socket via curl?

Also, is there a specific flag or option I’m missing? I tried `--raw` or `--tcp`, but no luck lol.

Thanks in advance! 🙏

(PS: sorry if this is a noob question, still learning!)
Hey! So, curl can indeed write to a socket via curl, but it’s not super straightforward. You’ll want to use the `--unix-socket` flag if you’re dealing with Unix domain sockets. For TCP sockets, you can use `telnet://` or `raw://` schemes, but curl’s support for raw sockets is kinda limited.

If you’re stuck, maybe check out `nc` (netcat) for raw socket stuff—it’s way more flexible for this kind of thing.
Yo! I feel you, curl isn’t the best tool for raw socket communication. You can kinda hack it by using `--data-binary` and `--output` flags, but honestly, it’s a pain.

For writing to a socket via curl, you might wanna look into `socat` or even Python’s `socket` module. Way easier to handle raw data that way.
Hey there! Writing to a socket via curl is possible, but it’s not the most intuitive. You can try using the `--unix-socket` option for Unix sockets or `telnet://` for TCP.

If you’re dealing with binary data, curl might not be the best fit. Tools like `nc` or even a simple Python script would be better for raw socket communication.
Hmm, curl isn’t really designed for raw socket stuff, but you can kinda force it. For TCP, try using `telnet://` or `raw://` in the URL.

If you’re stuck, I’d recommend checking out `socat`—it’s way better for raw socket communication. Curl is more for HTTP/HTTPS, so it’s not ideal for this.
Hey! Writing to a socket via curl is tricky, but doable. For Unix sockets, use `--unix-socket`. For TCP, you can try `telnet://` or `raw://`, but it’s not super reliable.

If you’re dealing with raw data, I’d suggest using `nc` or even a quick Python script. Curl is great, but it’s not the best for this use case.

Wow, thanks everyone for the tips! I tried the `--unix-socket` flag, and it kinda worked, but I’m still having trouble with TCP sockets. I’ll definitely check out `socat` and `nc`—seems like those are the way to go for raw socket communication.

Quick question though: has anyone used `socat` for binary data? Does it handle that well? Thanks again, you guys are awesome! 🙌
