raspberry pi zero w no ssh possible

Post by Reindier »

I have instaled DietPi_RPi-ARMv6-Buster.img with balenaetcher when i run this i have to setup wifi on first boot, i put in my wifi details and test the connection everything works afther the instalation is complete it shows my local network ip adress but no ssh is possible to this adress?

also tried to edit dietpi tekst with the wifi enabled and land disabled and edited the wifi tekst same result

it has a internet connection to install everything except for ssh, also tried open ssh to instal same result no ssh possible.

Hi,

many thanks for your message. Which SSH you are running now? Did you removed Dropbear before installation of OpenSSH? Can you check if there is a SSH server running on LISTEN on port 22

Code: Select all

ss -tulpn | grep LISTEN
Pls let us know if a solution is working. This could help others if they hit by similar situation. Your DietPi Team

that looks fine. Can you check Dropbear journal

Code: Select all

journalctl -u dropbear.service

good that it is working now. But the behavior reminds me on a case we had in the past. It took us quite some time to find out what the issue was and who blocked SSH access. At the an TP-LINK Access Point was preventing SSH access. If you have time, you can read through this post viewtopic.php?f=11&t=8298

BTW. A successful SSH connection will looks like this on the logs

Code: Select all
