Crossbreeder Plus 1.0.0 — the new version

Crossbreeder Plus is a ground-up rebuild of Crossbreeder that works many APs at once instead of one after another. It is a single executable — no installer, no Xojo runtime, no separate TFTP server.

Download it from the latest release on GitHub. Source and full README: github.com/andreacoppini/crossbreeder.

The binaries are unsigned, so Windows and macOS both warn on first launch. On macOS use right-click → Open, or xattr -d com.apple.quarantine crossbreeder-plus-macos-universal. SHA256SUMS.txt in the release covers every file.

Why bother

Measured against a live 558-AP estate: a full inventory sweep finishes in 6.5 seconds. The original Crossbreeder, working one AP at a time, takes over an hour on a list that size.

What changed

• It pings first. Most addresses on a site list are dead. Each dead one costs a single unanswered packet instead of an SSH handshake sitting on a timeout. Addresses that never answer are listed, folded into ranges, and can be exported to re-run later.
• It works the APs in parallel — inventory, firmware, factory reset, reboot, or any AP CLI command, across Solo, ZD, R1, SZ and Unleashed, at whatever concurrency the site can take.
• It hosts the firmware itself. No SolarWinds, no separate TFTP/FTP/HTTP server: it serves the image and control file, works out which of your local addresses the APs can actually reach, and shows what each AP is downloading.
• It follows the reboot. After the first pass it keeps re-pinging and re-reading the version, so an AP that drops off reads as Rebooting and one that comes back on a new version is reported as upgraded. The push is confirmed rather than assumed.
• It exports CSV and JSON, with a row for every address — including the silent ones.

Using it

Run it with no arguments — or just double-click it — and it opens a console in your browser, bound to the local machine only:

Crossbreeder Plus 1.0.0
Console: <http://127.0.0.1:52413>

Paste in your addresses (or load a CSV), set the AP credentials, tick what you want done, press Run. With nothing ticked it collects inventory. Tick keep re-scanning and it repeats the scan until you press Stop — the first pass does the work, every pass after that just re-checks.

Everything the console does is also on the command line, over the same engine:

crossbreeder-plus -csv aps.csv -user admin -ask-pass -c 50 -out results.csv

Use -ask-pass rather than -pass: cmd.exe eats ^ as an escape character, every shell claims a different set, and an argument is visible in the process list. crossbreeder-plus -h lists the rest.
