I just setup my PI yesterday with Raspbian and installed teamviewer but it will not boot if its not connected to a monitor. How do I get around this? Hi - I got the answer to this before thanks to Klricks: Use sudo raspi-config to set a forced screen resolution. (Choose anything other than monitor ...

Re: How to protect a brand new Rpi4

Can anyone please advise the risk I will run if I do not install the firewall? The router has a firewall set at medium level.

Can anyone please explain where are risks in a configuration without firewall?

Thanks for helping,

How to check Rpi4 memory available

Hello,
I have just bought a Rpi4 and unfortunately I did not check the memory chip before attaching the heat sink.

How can I check the total available memory from the GUI or from the command line?

Thanks!

Click the Raspberry, go to Preferences and select Raspberry Pi Configuration. Then in the Boot option under the System tab, change it to "To CLI". To get the desktop back from command line you run raspi-config.

Re: Question on headless mode

I install the "with Desktop" version of Raspbian even if that Pi will be run headless. I just find it easier to do my setup from the GUI. Once I'm all done I go into the Raspberry Pi configuration menu and set it so it boots to command line. No point in booting to a GUI with no monitor connected an...

Re: Question on headless mode

"Headless" is just shorthand for "no keyboard, mouse, or monitor". Since Linux doesn't complain about any of those being missing, it runs just fine, regardless of whether X is being run or not.

Re: Raspberry as access point for a WiFi device

I have a WiFi switch that cannot reach the main access point. Next to the WiFi switch there is a Rpi3 connected via Ethernet to the main lan and therefore to the router.

I would like to use the WiFi of the rpi3 to connect the WiFi switch to the main lan.

Any idea?

Thanks,
Dan

Hi! I suspect the script echos to nowhere. This variant logger -s "cable router success => gateway must be the cable router" should leave a line in syslog and also on the console.

Install Buster on your RPi3 and that will work on a RPi4.

Stretch went end-of-life in June with the release of the Rpi4.

Do you agree? Maybe if you have 5 minutes, you could advise how to add this check. I respectfully disagree to this addition, and also admit in shame to having erased the Buster copy I installed to test the script. As it is, the pinger tests the main router and flips to the other side until the main...
