I know this topic has been kind of touched on already, but is there a way to access my RPis locally, but remotely, if that makes sense?
Both of my RPis are in my loft, so if I want to try changing a gain, for example, I have to get up there and bring it downstairs to plug it into a monitor and spare keyboard etc.
I’m not bothered about internet access, just some way of accessing the command line stuff from my home PC on the same network
Headless access via ssh? That is usually the way to go. You‘ll have to enable it on the Pi and use a ssh client, eg putty for windows, on the other device. And it requires a little knowledge about how the linux terminal works, but that’s not that difficult und really useful to learn.
Well I have 3 x RPi4’s in my loft and when I initially set them up I install XRDP and use Microsoft Remote Desktop on either PC or Mac (nicer interface on Mac for some strange reason) so I get straight to the RPi desktop when connected.
I also use SSH but almost always reach for RDP when I need to access the Pi’s even if all I do when I get there is open a Shell to the command line!
I use ConnectBot which is a lightweight, powerful, open source SSH for Android. One can predefine connections and logins for one touch access to SSH enabled systems.
I’ve also added a Philips Hue smart plug, to the mains feed, so I can remotely power cycle my feeds, as I find that very occasionally the RPis will go off-line and cannot be reached.
