we did not send a packet, disable method

问题

I have tried to setup public key connection between AIX to AIX and that's working and I am facing problem while I setup same public key connection between AIX and DataPower appliance.

I could see in logs that's connection established but while using public I am not able to login and everytime expecting to enter password manually.

Can someone please help on this?

debug1: Authentications that can continue: publickey,password
debug3: start over, passed a different list publickey,password
debug3: preferred publickey,keyboard-interactive,password
debug3: authmethod_lookup publickey
debug3: remaining preferred: keyboard-interactive,password
debug3: authmethod_is_enabled publickey
debug1: Next authentication method: publickey
debug1: Offering RSA public key: ./***_rsa.pub
debug3: send_pubkey_test
debug2: we sent a publickey packet, wait for reply
debug1: Authentications that can continue: publickey,password
debug2: we did not send a packet, disable method
debug3: authmethod_lookup password
debug3: remaining preferred: ,password

I've just had the same problem. Two raspberry Pis on my local network - one connected, one didn't (with the 'debug2: we did not send a packet, disable method' error)

after 4 hours I found the problem Being used to uk spelling I created the 'authorised_users' file not 'authorized_users'

Doh !!

Refer to this answer SSH public key won't send to server.
In your log

Offering RSA public key: ./***_rsa.pub
...
we did not send a packet, disable method

It means that the client didn't send the key file. So make sure the key file exists.

So what happened for me is that I have 2 VMs to access from my local machine (2 keys id_rsa.pub and id_rsa2.pub). I realized that my ssh connection is using id_rsa.pub by default for any ssh user@xx.xx.xx.xx connection. I solved my issue by adding a config file and specify the identity to be used for every hose like the following :

vi ~/.ssh/config

Add both hostnames and their identity file as follows:

Host server1.nixcraft.com
  IdentityFile ~/Users/.ssh/id_rsa1
Host server2.nixcraft.com
  IdentityFile /backup/home/aymen/.ssh/id_rsa2
