Linux: not working with wired? connection

[passcod]

Migrated from #1417

I still have the problem after compiling from the right repo (commit af04e45 according to cargo install), logs below.

Observation: I noticed that it only have when my computer is on a wired connection (Ethernet over USB). On wireless, it works. I have a suspicion: my computer disables the WiFi conncetion when I plug it into ethernet (otherwise I get other problems). Perhaps binstall is trying to use the WiFi connection for some reason, even when it's disabled?

Let's see if these logs are any better. The final error is ~ the same as in my last comment. Again, I used cargo binstall cargo-nextest -y --log-level trace --json-output | tee out.txt.

Ah, I only just now noticed you're on Linux 😅. That explains why I couldn't find the log again (I was searching for the Windows log line). Given that this was initially only a problem on Windows, we only implemented the fix for that and kept using the auto system config on Linux. It really does look like trust-dns's system config is unreliable.

[excluded off-topic discussion of "why trust-dns"] Seems like we'll just have to port over the changes from the Windows-side to the Linux-side (find a replacement for the ipconfig crate, default_net can be removed since we're only using 1 small function which we can extract).

Hmm... trust-dns's system config reads the nameservers from /etc/resolv.conf, which could mean something might be wrong there? There might be more to this, but I'll have to look at the logs properly when I'm back.
