Re: Dual Gbit Port for Rapi (Opensene Firewall)

Re: DNS Nameserver Incorrect

So I don't trust these keys, you can't proof the oposite. End of discussion. :-)

I generate fresh keys on my raspis after installing fresh OS (and always when cloning cards for more raspis).

Re: SSH Connection from a non-local network

only the VPN server needs an open port, not the client. with bullseye even wireguard should be possible. but you definitely need a (dyn)DNS entry for the server to be able to establish a tunnel.

To me the question is: If the keys are generated THAT early during boot (no time/date yet), how much entropy is at that time in the system?

Re: Azure VPN through Wireguard PiVPN - 'Name Not Resolved'

The WG will modify resolv.conf on the raspi to only use 1.1.1.1 and 1.0.0.1 as DNS servers (as you provide these in the server config). But your resources via Azure are in a private address range (192.168.126.x, local domain hostnames), which can only be resolved from the DNS server of the network b...

Does the label on your aspirin make the tablet safer? Only if you read it, understand it and then follow the instructions. The label itself is useless, if not understood, absolutely clear.

Re: Problem connecting to raspberry pi zero W through ssh using hostname

This is a problem with your DNS (most likely your router/firewall) not registering the local hostnames for resolution and has nothing to do with the raspi, you have to look in your router (DNSmasq or unbound or something proprietary-looking in the GUI of your router). If you want to use the same IP ...
