Author of memreserver (one of the mentioned userspace workarounds) here. I've debugged this a few years back, only public comment I can quickly find is [1]. I also remember some mailing list discussions, but it basically came down to the isuse that Linux didn't have staggered suspend hooks that reliably ran before disks and parts of the memory subsystem were frozen. Apparently this is now possible. Sadly the Freedesktop Gitlab doesn't seem indexable so this knowledge seems to have gotten lost.

Anybody runs the HIBP password DB locally? (ideally with this latest treasure trove) I saw some converted it to a Bloom filter (which makes lots of sense: for all the passwords on which it answers 'definitely not in set', you know there's no false positive and in case it'd answer 'potentially in set' you could still query manually against the online DB).

I'll search online but if a fellow HNer runs it offline, I'm all ears...

P.S: I've got Gbit/s FTTH as well as servers in datacenters so downloading tens of gigabytes ain't an issue

I have a project which acts as a local cache for the HIBP database.

https://github.com/lorenz/hibp-cached

It downloads and continually updates from the upstream database while serving the identical API. On a fast link it can download the entire thing in a few hours.

It just uses a giant BoltDB file to store compressed chunks.

it uses websockets to get the information to the browser. a little weird, but whatever, my question is why does the socket remain open after the information is downloaded?

lorenzbrun · 10 years ago

It asynchronously pushes all info so that you can view everything as soon as the server gets it. It keeps the connections open because new requests also use WebSockets.

Nice!

Suggestion: Accept host names as well, despite the name of the service.

lorenzbrun · 10 years ago

Thanks, I'll put that on the todo list for the next version.

The website doesn't function without like 5 different JS libraries from another 3rd party, so it's not just Google logging your visits. Unfortunately, this is considered totally acceptable for some reason

edit: Just noticed it's also loading fonts from Google

Author here, it's actually only JSdeliver and Google (analytics.dolansoft.org is mine). I wrote the tool a long time ago (like 2 years), there is a new version available internally which minifies all resources into static files delivered from my own server.

Looks useful!

There are some issues with the port detection on my IP address though: HTTP was 'disabled' (whatever that means, but it's open and apache is listening) and SMTP was incorrectly labeled 'closed'. Https detection was correct, and ssh was 'closed', which could be correct if it means 'RST returned' rather than 'firewalled'.

Also I'd prefer seeing an OpenStreetMap tile rather than having Google log my visit, but that is probably just me. On the positive side, Piwik instead of GA :)

Another small point: I'm not sure which address you're looking for, but the whois info of my IP definitely contains an abuse address (80.100.131.150).

lorenzbrun · 10 years ago

Author here, I only include a static map, no JS from Google. But I'll look into it, I'm also not a huge fan of Google being able to log all visits.

Abuse mails get parsed from the RIR WHOIS data, this involves lots of regexes, which can be wrong sometimes. In your specific case it is the fact that it can't yet parse the remarks statement.
