ssh-copy-id ipaddress , Doing this on ubuntu.

the result says keys is added to the authorized keys section sucessfully

but when i do ssh ipaddress, its asking for password.

Where is the issue?

 

I have enabled PasswordAuthentication to yes in the sshd_config file.

did u go n check on the end node to see key is present in authorized keys file? if ues, try to do,export ANSIBLE_HOST_KEY_CHECKING=False. This may not be the issue, but give it a try.

you need to enable the password token and refresh it after one hour to login

auntentication file and it generates a password valid for 1 day . You can configure the password to expire after 1st authentication or reuse or expire in every 15 min or 1 hour or 24 hours

Have you checked whether your public key is copied to ~/.ssh/authorized_keys on the server? 

Is private key authentication enabled on server? Check in /etc/ssh/sshd_config

RSAAuthentication yes

PubkeyAuthentication yes

AuthorizedKeysFile /.ssh/authorized_keys

try the ssh with verbose mode (ssh -v)

on server check  /var/log/secure for more info

instead of using copy ssh command, can do it manually. Generate a key and copy it to target node to authorised key file and try.
