OK, there is just too much old information on the forums and I am unclear. I am having issues with SSH keys not remaining persistent after reboot. I cannot tell if there are some old entries in the /boot/config/go that need to be removed Here is the go file:

#!/bin/bash
# Start the Management Utility
/usr/local/sbin/emhttp &
#Copies all files needed for authorized ssh connections 
mkdir /root/.ssh 
cp /boot/config/ssh/* /root/.ssh/ 
cd /root/.ssh 
chmod 600 * 

Are the lines under "#Copies all files needed for authorized ssh connections" no longer needed so I can delete them? I am running Unraid 6.12.4

With the current release you don't need anything in the GO file, delete all those extra lines.

Persistent SSH is still a no go. I have

• created ed25519 keys for both servers (Unraid1 & UnraidBackup)
• Made sure the root users of each server have a copy of the key (I can see the key listed under the root user.)
• SSHed from Unraid1 to UnraidBackup by terminal and run the command

• Quote

  rsync -arv --delete --human-readable --info=progress2 -e "ssh -i /root/.ssh/id_ed25519" /mnt/user/docs/ [email protected]:/mnt/user/docs/

   

• Said "Yes" to add the SSH user to the authoized_users list
• I removed the entries in the go file that are no longer needed [see above]

Each time UnraidBackup is rebooted I am confronted with 

Quote

The authenticity of host '10.253.0.20 (10.253.0.20)' can't be established.
ED25519 key fingerprint is [key is listed here].
This key is not known by any other names.
Are you sure you want to continue connecting (yes/no/[fingerprint])?

Am I missing something?

This is how I do it:

 

Generate key:

ssh-keygen

NOTE: when generating the key use a blank password or it will ask for it anytime you use that key.

Copying your Public Key Using SSH:

cat ~/.ssh/id_rsa.pub | ssh root@remote_host "mkdir -p ~/.ssh && cat >> ~/.ssh/authorized_keys"

 

Do I need to remove any previous entries in authorized_keys?

Should not be needed, but you can also remove them.
