Re: Kids computer addiction

I like it heater, great comment :D Both of you though I feel not really facing everything about this common situation. I had a chance to think about it a bit more, comparing my own life and what I've done. When I was a kid I was big into computers at a time when they weren't in use like they were to...

Kids computer addiction

I remember fondly getting my first computer. A commodore. This led to many great experiences. In particular I became a bit of a geek and really as nerds we now pretty much rule the world! That is, the world now is an incredible place for a geek. I see people like Elon Musk and Eric Schmidt. I see it...

Thanks Heater. I'll give ReadOnlyRoot a try. However, if there's a better starting point for this (cheap opensource router with USB port?) then please let me know

Re: Unexpected shutdowns protection - different filesystem?

OK. I stumbled on the answer. No and no, apparently. Glad I take advice with a pinch of salt. It's a ramdisk. Well, it is on OpenWRT. Perhaps OpenWRT can run on Pi... ah, yes it does: https://www.raspberrypi.org/forums/viewtopic.php?t=145591&p=959666 Package support is poor but perhaps we can run th...

RAM disk for greater reliability

How do routers survive unexpected reboots?

RAMdisk, that's what.

Depending on your model and application it can be doable.

A lot of projects would benefit from this. At least we should be able to reduce the chance of fail to boot?

Re: Unexpected shutdowns protection - different filesystem?

OK.
I plan to schedule a shutdown before power cycle every day at night. But of course it's a good idea to use the best filesystem just in case, no?

Unexpected shutdowns protection - different filesystem?

NAS servers, routers, things like this have some sort of tolerance to unexpected shutdowns. You can just turn them off and they don't usually fail to turn back on. How do they do this? I want to make my Pi available remotely but I don't want it to become unavailable if the cleaner knocks the power s...

Re: Reliable remote access?

Thanks guys. I'm going to go the route of dataplicity for the NAT problem. I'm tending to go towards the approach of using a power timer to turn off everything once a day at night. I expect this to work well on the router but not sure on the Pi. I would set a cron job to shut down the Pi before the ...

Reliable remote access?

We're moving out of home and I'd like to use something like a raspberry pi for remote access and NAS for the family. The only thing is that I won't be physically in the country to access it if it goes wrong and our parents are IT useless - the most they can do is hit a reset switch. - If there somet...

Re: OpenVPN tutorial

It's good practice to merge all the keys and config into one single .ovpn file. Anyone know how to do that - an example with the right syntax.

By the way, ICSOpenVPN (OpenVPN for Android, not to be confused with OpenVPN Connect) gives false parsing error (see bug 177) in the config GUI so watch out.

Re: HDD overheats

This is true regards the heat. Also though I think is that 2.5" HDDs aren't designed to run 24/7 like a server. It's still good to shut it down when not in use. I've ordered a random USB adapter off ebay... no idea if it will support hdparm shutdown but it was so cheap I thought it worth a shot. If ...

My external HDD is overheating... it's a 2.5" IDE via USB adapter of course... unfortunately AFAIK the USB adapter doesn't support hdparm -y or -Y to spindown the drive.
