The input device is not a TTY

[jojebo]

Hi everyone,

I’m fairly new to ansible and I stumbled across a problem which I’m unable to solve.

Problem
It occurs when I try to run a playbook that should execute two commands (proprietary sw).
The error is either “the input device is not a TTY” or it just hangs with python indend errors depending on the -t or -tt flag for ssh.

Hosts file

[SERVERS] server

ansible_host=** dest ip **

[SERVERS:vars]

ansible_user = test2 ansible_port = 22

ansible_private_key_file = ~/.ssh/id_rsa

ansible_ssh_common_args='-tt -o ServerAliveInterval=30 -o ServerAliveCountMax=60'

Playbook

---

- name: test hosts: SERVERS

  vars: logfile: "/home/test/reports/{{inventory_hostname}}_{{ansible_date_time.date}}_{{ansible_date_time.hour}}-{{ansible_date_time.minute}}.log" loghost: "localhost" jumphost: "**src ip**"

   tasks:

     - name: ice tool

       shell: . ~/toolrc && tool

       async: 1200

       poll: 10

       register: output

     - debug: var=output.stdout_lines

     - name:

       find logs find:

         paths: "/home/test2/"

         patterns: "*2023-09*.log"

       register: files_to_fetch

     - name: fetch logs

       fetch:

         src: "{{ item.path }}"

         dest: "/home/test/reports/{{inventory_hostname}}/"

         flat: yes

       with_items: "{{ files_to_fetch.files }}"

I turned the debug output on.
ansible.cfg shows #usetty = True

Ouput

Is it really about the -tt attribute?
Or is there a python issue?

I might get beaten by this but I recall that it worked a few weeks before when I tried it but now it doesn’t anymore. No one touched the servers in the meantime.

After the script part worked I started to comment it and try to get the file copy part working. I guess I edited it to often.

“tool” runs perfectly fine when started directly on the destination.

I removed the ssh arguments → “the input device is not a TTY”
I set usetty to true → “the input device is not a TTY”
ssh -t test2@* dest ip ** “source toolrc && tool” → works
So it is basically possible to run the script via ssh with the -t argument.

If I delete these two lines

       async: 1200

       poll: 10

it works! But I would like to start the task on all of the servers at once which needs async, right?
