Show HN: unsafehttp – tiny web server from scratch in C, running on an orange pi

#1

Post by GSGBen »

Hey HN, I wanted to get more familiar with C programming, *nix socket programming and C compilation, so I wrote this "web" ""server"". It's running on a tiny SBC in my office, and there's as little as possible between you and it.

Happy for you to try and break it, hopefully with something more interesting than a DoS though :) Please let me know if you find any issues.

Whoops, should be back up now. I'll have to check logs later to see why it went down.

You're going to need a bigger host to support HN traffic :)

What is it about HN that overwhelms small servers like this? It was a small static page so I wouldn't think it'd be that much load on the server itself, even for an OrangePi like this one.

Too many simultaneous connections for his router maybe? Or too much bandwidth for his internet connection?

If they are behind a NAT/ stateful firewall there is just so much connections it will handle at once. I think OpenWRT has like 16K max by default, f.ex. So for less than 16K requests by different users/IPs… each is kept for about 1 minute I think… it quickly will go down, I guess. :)

cat /proc/sys/net/netfilter/nf_conntrack_max

Should give some details.
