Something like a raspberry pi or equivalent, and use reverse SSH set up to connect to a server with a known address on your end.

This means that ports don’t need to be opened on their end.

Also if you go with a gateway host, shift SSH to a randomised port like 37465, and install fail2ban.

I don’t think there’s anything commercially available that can do it.

However, as an experiment, you could:

• Get a group of photos from a burst shot
• Encode them as individual frames using a modern video codec using, eg VLC.
• See what kind of file size you get with the resulting video output.
• See what artifacts are introduced when you play with encoder settings.

You could probably/eventually script this kind of operation if you have software that can automatically identify and group images.

Stupider things have happened and if I was a detective you’d be damn sure I’d at least give this a try.

True. Hence my caveat of “most cards”. If it’s got LEDs on the port, it’s quite likely to signal which speed it is at with those LEDs.

I haven’t yet come across a gigabit card that won’t do 10Mbit (edit: switches are a different matter) but sometimes I’ve come across cards that fail to negotiate speeds correctly, eg trying for gigabit when they only actually have a 4 wire connection that can support 100Mbit. Forcing the card to the “correct” speed makes them work.

For later reference, the link light on most network cards is a different colour depending on link speed. Usually orange for 1G, green for 100M and off for 10M (with data light still blinking).

I have not cared about or terminated A-spec after network cards gained auto MDI/MDIX about 20 years ago.

Yeah , it’s really a little strange in OPs case, I can’t really recall changing a CMOS battery in ages, like decades of computer use.

1. Replace CMOS battery.
2. Get small UPS.
3. Discover that small UPS’s fail regularly, usually with cooked batteries.
4. Add maintenance routine for UPS battery.
5. Begin to wonder if this is really worth it when the rest of the house has no power during an outage.
6. Get small generator.
7. Discover that small generators also need maintenance and exercise.
8. Decide to get a whole house battery backup a-la Tesla Powerwall topped off by solar and a dedicated generator.
9. Spend 15 years paying this off while wondering if the payback was really worth it, because you can count on one hand the number of extended power outages in that time.
10. In the end times a roving band of thugs comes around and kills you and strips your house of valuable technology, leaving your homelab setup behind and - sadly - without power. Your dream of unlimited availability has all been for nought.

Conclusion: just replace the CMOS battery on a yearly basis during planned system downtime.
