Nicd<p><span>I started hosting a </span><a href="https://social.ahlcode.fi/tags/Valheim" rel="nofollow noopener noreferrer" target="_blank">#Valheim</a><span> dedicated server for my friends, but I didn't want it to be constantly running. I reached for </span><a href="https://social.ahlcode.fi/tags/systemd" rel="nofollow noopener noreferrer" target="_blank">#systemd</a><span> socket activation, where systemd will start and stop the server on demand. Unfortunately Valheim doesn't support it by itself and systemd's proxy doesn't support UDP.<br><br>So I wrote a small UDP </span><a href="https://social.ahlcode.fi/tags/NodeJS" rel="nofollow noopener noreferrer" target="_blank">#NodeJS</a><span> proxy to do just that. Here's the writeup: </span><a href="https://blog.nytsoi.net/2024/07/18/valheim-systemd-socket-activation" rel="nofollow noopener noreferrer" target="_blank">https://blog.nytsoi.net/2024/07/18/valheim-systemd-socket-activation</a><span><br><br>And here's just the code: </span><a href="https://git.ahlcode.fi/nicd/valproxy" rel="nofollow noopener noreferrer" target="_blank">https://git.ahlcode.fi/nicd/valproxy</a><span><br><br>CC </span><a href="https://mastodontti.fi/@mikeful" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@mikeful@mastodontti.fi</a><span> </span><a href="https://mastodon.tmm.cx/@hp" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@hp@mastodon.tmm.cx</a><span> <br><br></span><a href="https://social.ahlcode.fi/tags/JavaScript" rel="nofollow noopener noreferrer" target="_blank">#JavaScript</a><span> </span><a href="https://social.ahlcode.fi/tags/networking" rel="nofollow noopener noreferrer" target="_blank">#networking</a><span> </span><a href="https://social.ahlcode.fi/tags/UDP" rel="nofollow noopener noreferrer" target="_blank">#UDP</a><span> </span><a href="https://social.ahlcode.fi/tags/gaming" rel="nofollow noopener noreferrer" target="_blank">#gaming</a></p>
Nicd<p><span>So I made this little </span><a href="https://social.ahlcode.fi/tags/UDP" rel="nofollow noopener noreferrer" target="_blank">#UDP</a><span> proxy: </span><a href="https://git.ahlcode.fi/nicd/valproxy/src/commit/879287a6f419efc0b41602e764bbef0d614aeff7/index.js" rel="nofollow noopener noreferrer" target="_blank">https://git.ahlcode.fi/nicd/valproxy/src/commit/879287a6f419efc0b41602e764bbef0d614aeff7/index.js</a><span><br><br>It takes in UDP packets from a </span><a href="https://social.ahlcode.fi/tags/Systemd" rel="nofollow noopener noreferrer" target="_blank">#Systemd</a><span> socket and passes them on to a local target. This part seems to work well, as the server replies with its own packets. On line 168 these are written back to the original socket, using the source address and port (meaning the remote address and remote port of the client that sent the original UDP packet). To my knowledge, this should make the packets route right back to the remote client.<br><br>But currently I don't get anything back. All the replies are lost somewhere. I don't exactly know where, but I know it's after they're written to the Systemd socket and they don't appear in Wireshark on the client.<br><br>Have I misunderstood how UDP works? Or networking for that matter? Any common gotchas I should look at? (Except, of course, not doing this silly thing in the first place. But let's not get into that here.)<br><br>Please boost if you know any networking geeks. :)<br><br></span><a href="https://social.ahlcode.fi/tags/networking" rel="nofollow noopener noreferrer" target="_blank">#networking</a><span> </span><a href="https://social.ahlcode.fi/tags/help" rel="nofollow noopener noreferrer" target="_blank">#help</a><span> </span><a href="https://social.ahlcode.fi/tags/JavaScript" rel="nofollow noopener noreferrer" target="_blank">#JavaScript</a></p>

Beej 💾<p>This is a fascinating paper on actual error rates in network traffic. It's been known for a while that sometimes packets pass the link layer checksum, but fail the TCP layer checksum, which seemingly shouldn't be possible. But it is. The paper estimates errors arrive at the application layer at a rate of one in 16 million packets to one in 10 billion packets. They suggest that critical applications implement their own checksum. </p><p><a href="http://conferences.sigcomm.org/sigcomm/2000/conf/paper/sigcomm2000-9-1.pdf" rel="nofollow noopener noreferrer" target="_blank"><span class="invisible">http://</span><span class="ellipsis">conferences.sigcomm.org/sigcom</span><span class="invisible">m/2000/conf/paper/sigcomm2000-9-1.pdf</span></a></p><p><a href="https://mastodon.sdf.org/tags/networking" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>networking</span></a> <a href="https://mastodon.sdf.org/tags/tcp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>tcp</span></a> <a href="https://mastodon.sdf.org/tags/udp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>udp</span></a> <a href="https://mastodon.sdf.org/tags/programming" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>programming</span></a></p>
