Re: External Ip Address

There's nothing actually wrong - but there are issues you should understand. Traditional IP addresses are xxx.xxx.xxx.xxx and that is what most people are familiar with. This is known as IPv4. There is a problem in that available IPv4 addresses are running out. As a solution IPv6 has been introduced...

Email hosting on RPi?

My current hosting provider is shutting down so I need to find a new solution for email services. Just wondering if anyone here might already be running email services on an RPi? Existing service is simple POP/SMTP and I only need 5 accounts. I have a static IP available and own the current domain r...

Re: Is USB boot on RPi4 now officially supported?

Again, my thanks for another helpful reply.

I’m keen to get to SSD boot but I think I’ll wait until it’s all packaged.

Re: Raspbian rename to Raspberry Pi OS - a bad idea?

I consider the choice of name and the decision to rename to be good. "Raspberry Pi OS" is a professional umbrella and should add to the brand. I would like to see an agreed abbreviated format for clarity and convenience in technical contexts - such as RPiOS/32 and RPiOS/64. Only one opinion amongst ...

Standoffs - plastic or brass?

Just wondering about others' opinions regarding standoffs for mounting RPis? My preference is brass for strength but I always have concerns regarding causing a possible board short at the mounting hole - so I end up reluctantly using plastic instead. Current project involves mounting RPi4 to 3mm acr...

Re: Annual running cost of RPi4?

My thanks to all for responses - most appreciated! I particularly like the WattYear approximation which is excellent for getting a ballpark. It's evident that my initial mains draw assumption was wide of the mark. The conclusion looks to be that, for sensible (?) quantities, the annual running costs...

Re: Annual running cost of RPi4?

Thanks James. Specific use case is a 4GB RPi4 running Rosetta@home to contribute to the Covid-19 folding project. Only addition is a small fan which looks to be keeping temp around 52-55. I agree my 20W mains draw is being unfair to the (official) PSU I am using as I'm sure it's probably at least 80...

Annual running cost of RPi4?

Just trying to estimate annual electricity cost of running an RPi4 24x7. I'm coming up with just about £26 which seems high compared to other figures I've seen from various sources. I'm deliberately not sharing my maths (yet) because I don't want to influence calculations by others but I am using an...

Re: Running Raspbian from USB Devices : Made Easy

Just ran the script on a headless RPi4 with another Samsung T5 and again it worked perfectly.

It looks like the script automatically generates PARTUUIDs which (most probably) will be unique.

That's the behaviour I would want, is that assumption correct?

SD -> USB boot configuration script?

Hi, Been elsewhere for a few months so not current on the latest updates. Everything I've done before has been headless but I've just started using Desktop to see just how viable the Pi is as a utility computer. Initial impressions are positive but I want to run from SSD rather than SD. I seem to re...

Use the Lite image for your use-case. Remember to enable SSH when you burn the card to get started.

Yes, network boot has been added.
Is there any documentation available regarding network boot on RPi-4? I've trawled the board but most of what I've found looks to be a series of solutions to encountered problems …

Hybrid (SD + SSD) boot 101?

Just to confirm my understanding of the hybrid boot process (meaning boot from SD and then switch to SSD) for either an RPi-3 or 4 with Buster: The only partition needed on the SD card is the small FAT BOOT which simply holds enough to get the system started to the point of telling it to then look t...

Thanks to all for responses - I will retry the apt route over the coming days. Additionally I will burn a 2019-09 Lite to SD and have a wander round that just as an exercise.
