Cannot login without password even with SSH key
I have 2 shell accounts ont 2 different hosts:
shell A: shell I want to login using a SSH key (server-A.com)
shell B: shell I'm using to login to A without a password but using SSH key (server-B.com)
I emailed the server-A.com sysadmin who gave me the bellow tutorial URLs
I've done the following:
- Created a private/public SSH key on server-A.com using
ssh-keygen -t rsa -C username@server-A.comand put the private key on server-B.com
in~/.ssh/server-B.com - I ran
chmod 700 ~/.ssh/andchmod 600 ~/.ssh/server-B.com
I added server-A.com public key to to
~/.ssh/authorized_keyson server-B.com
cat ~/.ssh/server-B.com.pub >> ~/.ssh/authorized_keys # on server-B.com
I've checked
~/.ssh/config(no) and/etc/ssh/ssh_configwhich contained the following (other # comment lines not printed)
# PasswordAuthentication yes
SendEnv LANG LC_*
HashKnownHosts yes
GSSAPIAuthentication yes
from shell B:
ssh-keygen -f "/home/username/.ssh/known_hosts" -R server-A.com
I followed the tutorial on https://kb.iu.edu/d/aews and https://www.digitalocean.com/docs/droplets/how-to/add-ssh-keys/create-with-openssh/
Can you tell me what went wrong ? Thanks.

Running yoursshcommands with the-vvvoption will provide a lot of debugging information that can narrow down the problem.

There should be a publickey authentication option on the host in the file /etc/ssh/sshd_config. Uncomment and set to yes
Ensure you are editing /etc/ssh/sshd_config on the host, not /etc/ssh/ssh_config. The second files is for clients only
