/boot/config.txt: open for write: permission denied

DrFreeman

Ah I found the mistake - it is not sshd_config - it is ssh_config.

But I can not find that line with
PermitRootLogin without-password

It is strange because with the sudo su psswd I could change the root passwort successfully?!

@DrFreeman you need to do sudopasswd root. But you have to fiollow the guide i posted to enable root password first. Then you need to restart the pi for it to work.

edmaul69

@DrFreeman i just tested it. It is /etc/ssh/sshd_config

edmaul69

@DrFreeman look at the file name at the top. and you see under authentication you see i have:

PermitRootLogin yes

alt text

Also if you cant get it working, the /boot folder is accessible on a windows computer so you could manually change the config.txt. But it would be better if you could get root access.

DrFreeman

@edmaul69 said in /boot/config.txt: open for write: permission denied:

Login, and edit this file: sudo nano /etc/ssh/sshd_config

Thank you very much but when I do that the file is blank - it seems it does not exist. Please could you tell me the steps? Sorry I am a noob with the pi :(

@DrFreeman ssh_config and sshd_config are 2 different files. try adding this to /etc/ssh/sshd_config and then restart your pi. you might need to install some package that is not on your pi.

ok so should I add just a blank file first and just reboot?

edmaul69

@DrFreeman put this in the blank file, save then reboot.

DrFreeman

Man, thank you very much and for your patience!!! Really - you made my day :D
