ansible ssh connection issue with cisco nxos after upgrade to 9.3(9) s

Morse — Mon, 08 May 2023 18:07:41 GMT

I am using an Ansible Server to connect to a Cisco NXOS Switch (N93180LC). The connection runs over paramiko using ssh user/password and has always worked without a problem until I upgraded from 9.3(8) to 9.3(9) software release. When I downgrade the software, then the ssh-connection works again. The connection works also with other devices using the same ssh user/password that are not on version 9.3(9).

SSH-connection over putty works just fine with the same user/password for the nexus switch. It only doesnt work over Ansible. Ansible is on version core 2.11.7 with python 3.6.8.

The ssh-connection is attempted both with a playbook and simply with "ssh user@ip-of-switch" on the Ansible Server. When "ssh user@ip-of-switch" is attempted, the process just gets stuck as if its still "loading". The error output from playbook is appended at the end of the post. myccpay account

The playbook content is not posted here because it works fine with other devices. It basically just has one task asking the nxos to show hostname.

I thought the problem may be fingerprint related, so I have set ansible_host_key_checking = False in ansible.cfg. Just to be sure, I also manually added the fingerprint from the switch (which i got with "show ssh key") to the ansible known_hosts file.

I've also tried setting ansible connection to libssh instead of paramiko.

Is there maybe a bug with the 9.3(9) release specifically in combination with Ansible that I have not been able to find? I would be appreciative of any help I could get!

But none of the above could solve the problem. The output error that I get from ansible is as follows:

This question appears not to have anything to do with NSO, so you are probably posting in the wrong forum
Cheers,
