Re: Raspbian lite vs desktop version, program list?

I personally start with Lite and install the stuff that I want/need. I've scripted the installs, which makes it much easier to rebuild (did I have that installed before or not? :o ) Using this I can go from blanks SD card to ready to rock in a relatively short amount of time, assuming that the inter...

Re: Upgraded to Buster - Bind9 Failing to Start

AFAIK bind9 doesn't set up a chroot jail by default. See https://wiki.debian.org/Bind9#Bind_Chroot , which describes how to set up a chroot jail for Bind9.

Re: Static IP Drops

A slightly more involved but problem-solving solution would be to have a DHCP and DNS configuration that is a) super-easy to install and configure, and b) lets you easily add/delete/modify static DHCP-assigned addresses for your network. This enables each of your RPis, phones, PCs, etc, to be config...

Thanks bls, now VNC is ready. Any tricks to speed up VNC? Glad you got it working. I'm not super-familiar with specific VNC speed ups, but there are some VNC tuning knobs available in the VNC client app. These depend on which client you're using, of course. What performance issues are you seeing?

Speculatively I wonder if a difference in the way xterm does a visible bell vs the way bash does it is the cause, and that somehow the root cause is related to the new graphics processor in the Pi4. xterm (and X11 in general) can use graphics primitives to flash the visible bell, while I suspect bas...

You could force some rsync logging to see if that helps in determining where it's hanging up. Change your rsync command to: rsync -a -e ssh /home/pi/Public/ pj@10.1.1.155:/home/pj/Public 2>&1 >> /home/pi/rsync-backup.log Of course, change /home/pi/rsync-backup.log as you'd prefer.
