multiple aliases in /etc/hosts broken in 5.x kernel

Somewhat esorteric problem - I'm using pihole as a "local dns". My pihole is running stretch, kernel version 4.19.66. I have a line in /etc/hosts that looks like this: 192.168.75.51 myhost.mydomain hosta hostb From there, I can ping myhost, hosta or hostb and get results From any OTHER ser...

Re: / mounted as /dev/root

OK - s it looks like most X86 distros (I've tested Debian, RHEL and Oracle Linux) all do the "pivot_root" thing. Would it be possible to do that w/Raspbian?

Thanks!

/ mounted as /dev/root

I've found an inconsistency between fstab,, what the "mount" command returns, and /proc/mounts I have some monitoring software that looks compares /etc/fstab with /proc/mounts to make sure that all local filesystems are mounted. On my Ubuntu linux servers, this works fine. But, on my Raspb...

Re: STICKY: How to upgrade a Wheezy image to Jessie (both defunct and replaced versions of Raspbian)

Data Point - I have several Pi's that are running wheezy in remote and headless configurations, I just tried this process to upgrade one of the oldest (1st Gen Pi B) and it worked just great. I did "apt-get dist-upgrade (no "y") and looked at each config, installed most of 'em but kep...

Re: Pi Zero W High Temp

Checked the power draw - couldn't see any added draw (~750ma/pi) for that particular Pi. Removed the enclosure, and all of the Pis dropped temps by about 10 degrees C -the others all running between 30 and 40 (as opposed to 40 and 50); but the "offending" Pi was still at over 60 C. Tried s...

Re: Pi Zero W High Temp

Thanks! I left it running overnight and it is now shut down (I'm traveling and can only reach them remotely right now). Don't think it's power because the other 9 are still OK and on the same power bus (total draw - for 10 Pi and Camera combos 6-7 A 5.5VDC at the supply, 5.2V at the Pi). I have anot...

Pi Zero W High Temp

I've got a set of 10 Pi Zero W's running cameras - they're all running the same image and the same workload. They're in an enclosure (but ventilated with a fan), because they're going to wind up outdoors. 9 of the Pi's report temps in the 45-48 C range; but ONE Is reporting a temp of 75-78 C. Can an...

Re: WiFi Issues ? Start here !

HELP! I've got two PI Bs, and had a NetGear N150 dongles running just fine. Then, I added an Access Point (to connections better in a rather large home) AND did "update/upgrade all", and now, my dongles won't talk. I tried disabling the new Access Point, and that had no effect. I ALSO trie...
