How to write an Ansible Module that does not do the initial check '/bin/sh -c '"'"'echo ~ && sleep 0'"'"''

Hi,

I am writing a module to a storage nas that allows me to connect to it using ssh. However, it does not provide a standard shell. So I cannot connect to it using command and shell modules. It works with raw assuming I set gather facts = to no.

The reason is that Ansible seems to always do the initial connection with ‘/bin/sh -c ‘"’“‘echo ~ && sleep 0’”’"‘’ to check if it can connect and fails if that command fails. As there is no home directory or /bin/sh the connection fails.
Here is the error:

<192.168.xx.xx> SSH: EXEC ssh -C -o ControlMaster=auto -o ControlPersist=60s -o KbdInteractiveAuthentication=no -o PreferredAuthentications=gssapi-with-mic,gssapi-keyex,hostbased,publickey -o PasswordAuthentication=no -o ConnectTimeout=10 -o ControlPath=/home/somename/.ansible/cp/xxxx 192.168.xx.xxx ‘/bin/sh -c ‘"’“‘echo ~ && sleep 0’”’"'
<192.168.xx.xx> (255, ‘’, ‘Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password,keyboard-interactive).\r\n’)
fatal: [somenas]: UNREACHABLE! => {
“changed”: false,
“msg”: “Failed to connect to the host via ssh: Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password,keyboard-interactive).\r\n”,
“unreachable”: true
}

Using raw avoids the checks and is a solution. However, I would Like to write a module to manage the storage in a better way. However, it seems like the connection is always happening using the above connection. I have tried both by using the standard way of using AnsibleModule and to write my own connection using paramiko SSHClient. But even when just calling this simple module Ansible is still first trying to do the ssh connection first before the connection from my module is invoked.

So my question is can I avoid the initial connection or change the specific check ‘/bin/sh -c ‘"’“‘echo ~ && sleep 0’”’"'’ to something that works on this storage?

Thanks,
Mikael

See the networking modules, specially those using network_cli as
networking appliances have the same issue, ssh access but no real
'shell' environment.
