Welland SDRs

The site's Raspberry Pi software-defined radios: what each is doing, and whether you can reach it.

Your connection to the site

ten64's healthchecker status could not be read; the Checker column is empty.

Reading the table

You: Your browser fetched the address directly. The only column that says whether you can use it.
ten64: The site router fetched it for you. ten64 shares the SDR hosts' network, so this is the best answer to "is the device up?". It is also how the mode is read: the SDR hosts send no CORS headers, so a browser cannot read their status itself.
Checker: ten64's nginx stream healthchecker, which TCP-connects to each host's port 443 every 5 seconds. IPv4 only.
Verdict: If ten64 reaches an address and you don't, the page uses your connection box above to tell your network has no IPv4/IPv6 apart from filtered between you and the device. From outside the site, the SDR hosts' IPv6 addresses are not published for HTTPS, so expect the IPv6 rows to show as filtered there; use the IPv4 names.

Host list: ten64's healthchecker plus sdrs.json.
