I'm having trouble "sshing" to localhost and getting a permission denied. I have tried everything from root or using sudo as well.
I'm having trouble "sshing" to localhost and getting a permission denied. I have tried everything from root or using sudo as well.
Ran the following:
ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsacat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keyscat /root/.ssh/id_rsa.pub >> ~/.ssh/authorized_keyschmod 0600 ~/.ssh/authorized_keysssh localhostAs the root user I have also done the following in case I use either user and the directories get mixed up:
cat /root/.ssh/id_rsa.pub >> /root/.ssh/authorized_keyscat /home/shervleradvm/.ssh/id_rsa.pub >> /root/.ssh/authorized_keysFirst time was because the service was not running. So I did sudo service ssh start
I have also disabled the ufw for the test. sudo ufw disable
read/write permissions on the key files are
drwx------ 2 shervleradvm shervleradvm 4096 Nov 21 23:15 .drwxr-xr-x 6 shervleradvm shervleradvm 4096 Nov 21 23:25 ..-rw-r----- 1 shervleradvm shervleradvm 1146 Nov 21 23:23 authorized_keys-r-------- 1 root shervleradvm 2610 Nov 18 13:17 id_rsa-r-------- 1 shervleradvm shervleradvm 577 Nov 18 13:17 id_rsa.pub-rw-r--r-- 1 shervleradvm shervleradvm 444 Nov 18 15:05 known_hostssshd_config file was missing the following so I added and tested each and combinations of:
- AllowUsers: added shervleradvm
- AuthorizedKeysFile: added ~/.ssh/authorized_keys /root/.ssh/authorized_keys
I then changed my config file a little after reading Please explain the complete steps involved in the installation of OpenSSH server on Ubuntu so now it looks like:

I'm not sure what else I can try I've been stuck on this for days and I have read all the other questions regarding ssh.

I just tried ssh -i id_rsa localhost from ~/.ssh dir of shervleradvm user to try defining private_key to use. That didn't work. So I did touch config && vim config then I defined the private key for the localhost:
Host localhost HostName localhost User shervleradvm IdentityFile ~/.ssh/id_rsaand then ran ssh localhost. The error presists.
UPDATE 4:I changed the owner of the private key to shervleradvm and gave the following permissions:
