netsleuth confirmed free on PyPI (pypi.org/pypi/netsleuth/json -> 404).
Publish still can't run until a PyPI Trusted Publisher is registered for
this project and the pypi GitHub environment exists with a reviewer rule -
both need account access this session doesn't have.
probes/traceroute.py imported async_traceroute from icmplib, which doesn't
exist in icmplib 3.0.4 - only a sync traceroute(), no async variant, and no
privileged= kwarg (traceroute always needs a raw socket, unlike ping's
unprivileged datagram option). The tier raised ImportError on every call and
silently fell through to the next tier. Call the real traceroute() via
asyncio.to_thread instead, drop the nonexistent privileged param.
Every probe used to follow whatever the OS default route picked, with no way
to point the tool at a specific adapter for comparison (VPN vs raw) or to
confirm which one actually carries traffic on a multi-adapter machine.
New iface.py resolves an adapter name or IP to a BindTarget (pure, tested):
exact/case-insensitive/unique-substring name match, rejects APIPA-only,
link-local-only and down adapters. Wired through every httpx provider client,
the Ookla binary tier, ndt7, and the whole ping/traceroute cascade (icmplib,
mtr, unix traceroute, TCP connect, scapy) plus --watch. Windows icmp_win now
uses IcmpSendEcho2Ex (adds SourceAddress) only when a bind is forced, so the
unforced path is unchanged. Windows tracert has no IPv4 source-address option
(verified from its own usage text) so that tier is dropped when forced,
noted in the report rather than silently measuring the wrong path.
An unresolvable/down adapter aborts with every adapter listed; a resolvable
adapter with no route to the internet degrades gracefully instead of
aborting - that's a real diagnostic answer, not an error. netinfo's
observation of the OS's actual default route stays untouched, so the report
can show the forced adapter and the OS default side by side.
Verified live: forcing Tailscale (no internet route on this box) triggered
the preflight warning and degraded correctly; forcing Ethernet ran clean
end-to-end including a full speedtest+MTR cycle.
Also noted, not fixed: probes/traceroute.py's icmplib tier imports
async_traceroute, which doesn't exist in icmplib 3.0.4 - that tier has
always raised ImportError and silently fallen through. Found while
verifying the icmplib source-binding wiring live.
_default_gateway() took whichever 0.0.0.0 line route print printed first,
not the one Windows actually uses (lowest metric). With a VPN adapter
installed (Radmin VPN, Tailscale, ...) its default-ish route can print
before the real one. Verified live: was reporting Radmin VPN's 26.0.0.1
while Ethernet (the interface actually carrying traffic, confirmed via
primary_interface_ip()) has gateway 192.168.3.1; now reports that correctly.
Parsing extracted into pure _parse_windows_default_gateway(), tested against
a captured multi-adapter route print sample.
path_findings() flagged ICMP rate limiting as real loss whenever two
consecutive traceroute hops both went silent, but real transit paths
routinely have long runs of silent hops (10 in a row, confirmed on a live
--full run) while the destination itself answers cleanly. Only flag loss
that persists all the way to the last hop in the trace; a run that clears
before the end is now ignored regardless of how many hops it spans.
Every run used to write all three files (en.md, ru.md, json) unconditionally.
Default is now English Markdown only, sourced from output.formats in
config.yaml; --format/--ru/--json pick exactly what a run writes, and any
explicit --format replaces the default rather than adding to it (all/none
supported). write_report() moved from a fixed 3-positional-arg signature to
a {format: text} mapping so writes are conditional instead of always-three.
The en/ru Markdown cross-link header is now only set when both languages are
actually being written.
