Auto Login Raspbian Jessie

[J0RDIE97]

Hi, I'm trying to make a project for uni that requires the pi to reboot a couple times. Only issue is that the pi needs authentication to login everytime the pi is rebooted. Is there anyway of overcoming this, or changing the startup process such that it does not need to login. This is for the ssh btw.

Is there anyone that can help?

Can't you use raspi-config and set console or graphical environment auto-login?

Investigate the use of public/private key pairs for ssh authentication. By using an agent on the 'remote' [non-RPi] device to provide the private part of the key-pair, login can be made to look 'automatic', while still being secure.

You can set up Rasbian to automatically log in without user interaction. The reason why Linux is not allowed to log itself in at boot, is for security reasons. Also you really do not need to in order to run a Cron job to do the timed reboot.

Do you know of a good tutorial to go through this process? Much appreciated!

Redhat has plenty of them. Since you are doing a timed job, it is only going to need to be ran as a Cron Job as I mentioned before.

If you let it be logged in. Anyone can access it. Make sure you disable Wifi and Bluetooth if a Pi 3. Also disable SSH and FTP ports.

If you've created a key with the ssh-keygen command, you can just copy that key to the machine you want to be able to access without a password using the ssh-copy-id command, e.g.:

ssh-copy-id wally@jimmy

Your ssh configuration information for each account is normally stored in ~/.ssh which won't exist until you've run the ssh-keygen command. Investigate the file ~/.ssh/config which can be used to store details for the account's ssh use including for each command. For example:

Host bobby.ssh
HostName wally
user jimmy

Then you can run your script with

ssh bobby.ssh

and it will automatically log in. The advantage of this over just typing ssh jimmy@wally is that you can have a lot more configuration details than I had above including sharing ssh connections so you can go in and out of programs that connect ssh without the overhead of authenticating each time.

Also disable SSH and FTP ports.

Are we answering the same question?

Because I am answering the one where @J0RDIE97 says: "this is for ssh"

If the OP is doing a unit like they want. SSH, FTP & SFTP need to be locked down. Along with if it is a Pi3, Bluetooth and Wifi not enabled.

They really just need a Pi and a small non-touch LCD screen to show the output.

So if the original poster wants to automatically log in with ssh, they need to disable ssh? What he seems to be building involves, it appears, only logging in via ssh.
