I don't have a monitor which accepts HDMI, so my only way to log into my Raspberry Pi is through
ssh on another machine. To do that, however, I first have to retrieve my Raspberry Pi's IP on my local network. The problem is that my Raspberry Pi doesn't show up when I scan all listening devices. I tried with
nmap and then
ssh to all shown connected devices, but none let me log in as user pi with password raspberry. I connected to my router website, which should contain a list of all devices which are currently connected, but, still, the raspberry pi is not in it.
I have a Raspberry Pi 2B. I tried installing the latest Raspberry OS from scratch, both the full version and the light one. I reduced the raspberry pi installation to power supply, SD card and Ethernet cable. I checked the light pins: the PWR one lights continuously, and the ACT one turns on and off with a high frequency for the first ten-twenty seconds, and then switches completely off. According to the documentation and various forums, it's quite normal behavior for a Raspberry Pi which succeeded booting. Of course, the Ethernet lights are on and the cable works fine with other computers. I finally looked for possible issues in booting, crawling on forums for problem symptoms that matched my case. But found none, my Raspberry Pi seems to work normally, except that I can't connect to it.
Last time I used it (few years ago), it worked like a charm.
Would it be possible that, by default, it doesn't connect to the local network (which would be weird for a debian-like distro such a Raspberry OS, but you never know...)? If so, how can I force it to do so?
EDIT: Some clarifications needed I think:
- I put a file called
sshwithin the boot partition (I already did this in the past, so I know the procedure);
- my router ip management is a standard DHCP, and it refuses static IP;
- I have full access over all the devices connected to it, checked them all and the pi is not in there;
- I already tried to
nmapmy whole subnetwork (without success);
- finally, I only have Linux systems.
I'll try to connect my raspberry pi directly to an other computer an simulate a DHCP server, to see how it reacts.
