Re: Execute script without seeing

autostart relies on the desktop environment starting. systemd doesn't. For a daemon process, systemd is desirable. To check it has started you can use systemsctl status servicename Or to check it's running ps -ef | grep programname Replace "servicename" and "programname" accordin...

Re: Pi won't boot up at a client's location, works fine at my house.

I am wondering if 2 different wall outlets in the US can have different voltage supplies, but even if that is the case, the onboard SMPS should take care of that. I heard recently (can't remember where) that US power may be 110-120V OR 230-240V. Since I can't remember where I heard this, I can't ve...

Re: New Pi user- unclear about loading software onto Pi 4.

From a quick look around the interweb thingy, there is no ARM port of bigwig, and no plans for one. Using the Windows version via WINE (there does appear to be a Windows on ARM version somewher) could be an option, but even then it may fail, and would likely be unusable. Probably better to search fo...

Re: Windows 10 on raspberry pi using QEMU

The Raspberry Pi has 1GB memory, running Qemu / Windows 10 Desktop Editions is simply not sane or feasible... It's potentially doable if you know enough about Windows to be able to strip it back to the bare essentials, and even then would be painful to use, entirely impractical and next to useless....

Yep - seems something on that singular directory (the one with rootfs for that Pi) got messed up when I migrated from a spinner to SSD. A reinstall from scratch, and it's working again.

[SOLVED] Suddenly failing to boot over NFS

I'm stumped on this. My config: 5 RPis - 4 x 3B+ and 1x 4B. The 4B has a connected SSD, with three partitions. The first partition is the FAT32 boot partition, the second is fsroot for the Pi4, and the third has data and, more importantly, directories that contain rootfs for the other Pis. The other...

Re: Can I boot from the same drive that I intend to use as a NAS drive?

You can but I prefer to keep the OS on a seperate drive to my data. Several reasons: [*]You can set the data drives to spindown when idle to save energy and wear. The OS drive won't spin down as often. Which is good advice if you are using a mechanical drive, and likely more damaging if you are usi...

It's possible you could do this without having to mail to anyone, and possibly get wider exposure.

Try a different port than 220. 220 is reserved for IMAP V3. Try a higher number (such as 2200).

Re: file system to use for external drive?

I would typically recommend ext4, but if it may be connected to a Windows machine your options are limited to FAT32 or NTFS. NTFS is the more secure system, but you should use the ntfs-3g kernel module, rather than just the ntfs module.
