I am the maintainer of `citrix.adc` ansible collection and we have a [ssh\_connection\_plugin for the `citrix.adc` ansible collection.](https://github.com/netscaler/ansible-collection-netscaleradc/blob/citrix.adc/ansible-collections/adc/plugins/connection/ssh_citrix_adc.py)

When I run ansible-playbook using this connection plugin, I am facing some unknown error which is difficult to debug. Maybe because I do not know the nitty-gritty of the working of the `shell` module.

ansible-playbook command ran:

```bash
ansible-playbook nsver_info.yaml -i inventory.ini -l mpx --ask-pass -vvvvv

```

Below are the details

Thanks in advance

## Playbook gist

To run `show ns version` on the NetScaler CLI prompt.

## Manually SSH into the ADC and run the command which playbook runs

> as soon as we SSH into the ADC, we will be in NSCLI prompt (not shell prompt). We need to type `shell` command to take us into shell prompt.

> The intention of our connection plugin is to run tasks directly into `shell` prompt.

> I believe, we are getting error before running any tasks!

What result do you get if you try manually run the command Ansible ran?

I think this is the command to try (after correcting the IP address):

```bash
export SSHPASS=YOURPASSWORD
sshpass -e ssh -vvv -C -o ControlMaster=auto -o ControlPersist=60s -o Port=22 -o 'User="nsroot"' -o ConnectTimeout=10 -o 'ControlPath="/home/sumanthl/.ansible/cp/90241bcd3b"' 10.x.x.42 'shell /bin/sh -c '"'"'/var/python/bin/python && sleep 0'"'"''

```

There is a note in the description of this plugin that says “The only authentication method that works with this plugin is with ssh key file”, so I think this failure is expected. It’s not a great UX to permit the configuration of authentication methods that don’t work, but that appears to be the current state.

@chris, below is the output after trying the command you mentioned.

It keeps retrying the the end step. I had to interrupt it to end.

```bash
❯ sshpass -e ssh -vvv -C -o ControlMaster=auto -o ControlPersist=60s -o Port=22 -o 'User="nsroot"' -o ConnectTimeout=10 -o 'ControlPath="/home/sumanthl/.ansible/cp/90241bcd3b"' 10.x.x.42 'shell /bin/sh -c '"'"'/var/python/bin/python && sleep 0'"'"''

I’m afraid I don’t know not sure what the result mean… What happens if you change the final command in the line to do something else, like print the uptime?

@chris below is the output when we replace the last command with `uptime`

```bash

I’m out of my depth here but it seems off that the device reported _“Session expired or killed. Please login again”_ prior to _“No such command”_?

Was `uptime` a bad choice for a test command, does the target device have a `uptime` command? Perhaps try something that it does have? 🤷

I tried with `sshpass ... 10.x.x.42 'uptime'`

Should I have tried with `sshpass ... 10.x.x.42 'shell uptime'` ?

I don’t know, I’m afraid I’m guessing at this point…
