gotatun

Userspace WireGuard® Implementation in Rust

Runs with mockssource: GitHubhomepageRustMPL-2.0commit 2a867b3f322d

Rust, MPL-2.0 licensed. The project labels itself: vpn and wireguard.

gotatun runs, with stand-ins for the services it depends on. An Argusic agent installed it in 9 minutes and hit 4 errors and fixed every one without help on a clean machine with no GPU, and the whole session was recorded.

GotaTun builds with cargo, installs via 'cargo install --bin gotatun --path gotatun-cli', its --version answers 'gotatun-cli 0.10.2', and its library unit-test suite passes 76 tests, with 4 IPv6-bound socket tests failing solely because this rootless container has IPv6 disabled.

What the agent ended up with on a clean machine, in its own words. How this is measured

Measured by Argusic on a fresh machine every time. Every number links to its evidence. Argusic Score 92 of 100 (the mean of this project's run scores).

What was measured

From the run that decided this verdict. Every line is a recorded value, not an estimate.

Time lost to each failure while testing gotatun, drawn from the recorded run
Every bar is a failure the agent recorded, with the time it cost. Drawn from this run, not from anywhere else.

What went wrong, in the agent's own words

The agent's own words, worst first, never rewritten into advice.

  • cargo test --lib: 4 IPv6-bound UDP socket tests fail with 'Cannot assign requested address' (os error 99)3 minutes
  • Default run and real tunnel bring-up cannot be completed: /dev/net/tun absent, mknod not permitted, no CAP_NET_ADMIN2 minutes
  • README cargo install --bin gotatun --path . fails: 'found a virtual manifest ... instead of a package manifest' (root Cargo.toml is a workspace)1 minute
  • gotatun -f gotest fails 'NULL from getlogin' (drop_privileges, no controlling tty in container)1 minute

What was not measured

The other half, so you can see exactly how far this evidence goes. A gap is printed as a gap and never filled in.

Peak GPU memory
this ran on a CPU machine, so there was no GPU to sample
Behaviour over a long run
each attempt uses the smallest documented settings and a fixed time budget, so this measures whether it runs, not how it holds up under load
Behaviour against real services
this run was verified against stand-in services only

The end of the recording

The last lines of the terminal session that decided this verdict, exactly as they were recorded.

**What I did**
- Installed the Rust toolchain (`rustup` + auto-selected 1.95.0 per `rust-toolchain.toml`).
- Built the project: `cargo build --bin gotatun` (debug) and `cargo build --bin gotatun --release` …
- Ran `cargo test --lib`: **76 passed, 4 failed, 7 ignored**. All 4 failures are IPv6-bound UDP soc…
- Verified `./target/release/gotatun --version` → `gotatun-cli 0.10.2` (exit 0), and `--help` works.
- Installed via `cargo install --bin gotatun --path gotatun-cli` → `/home/runner/.cargo/bin/gotatun…
- Left the repo unmodified (`git status` clean).
**Key findings (errors recorded)**
- README's `cargo install --bin gotatun --path .` fails (virtual workspace manifest); correct path …
- 4 IPv6-socket tests fail in a rootless/no-IPv6 container.
- Real tunnel bring-up needs root/`CAP_NET_ADMIN` and a TUN device, both absent here (README docume…

Replay the whole session, every command from a clean machine to this point.

How it was tested

One agent, one container, no human help. It installs the project the way its own documentation says to, runs it, and fixes what breaks. Everything below is recorded as it happened: the terminal session, the log and the exact commit. The full method.

Strengths and limits

Measured facts, not opinions. How this is written.

What went well

  • Installed in 9 minutes.
  • Recovered from all 4 errors without a human stepping in, which says the failures are documented well enough to solve.
  • Licensed MPL-2.0, as reported by its host.

What did not, or is not known

  • Only reached a running state against stand-in services, so nothing here proves it works against the real ones.
  • Measured once so far. A single attempt shows it can run, not that it runs reliably.

Also tested, in the same area

Every one of these was installed and run by Argusic on a clean machine. Nothing appears here that was not tested.

Questions

Does gotatun run?
gotatun runs, with mocks standing in for external services. Argusic installed and launched it on a clean machine in 9 minutes, hitting 4 errors on the way, and recorded the session.
How did Argusic test gotatun?
On a fresh, disposable machine, with every command recorded and the repository pinned at commit 2a867b3f322d. One attempt is recorded, and the full method is on the methodology page.
What did it cost to test gotatun?
The run that produced this verdict cost $0.07: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
How long does gotatun take to install?
9 minutes in the run that decided this verdict, from a clean machine to a running state. That is one measured attempt, not an average.
Does gotatun need a GPU?
Not to start. Argusic reached a running state on a machine with no GPU.
What goes wrong when installing gotatun?
4 things broke in the recorded run, and 4 were fixed without human help. Each one, and the time it cost, is listed on this page.
Where is the evidence for gotatun?
The recorded run is on this page, each linking to its full log and terminal recording, stored with a sha256 fingerprint so it cannot be quietly altered.
