This question does have some history from this post: Auto exit Telnet command back to prompt without human intervention ^] quit close exit code 1
Btw, I'm trying to test a port using telnet command where the port can be OPEN or NOT. How can I do the same in Ansible?
I tried the following but (whether port is open or not open/it's invalid), Ansible always says it 'failed': true in the results or output dictionary variable and return code 'rc': 1
I tried command module and shell module as well but it didn't work.
HOW should I do to get Ansible run this telnet command successfully so that next actions (defined in the playbook's tasks) can work.
My playbook snippet:
- name: Ensure collector agent's proxy_address and proxy_port is open
#command: "echo -e \"^]\\nclose\"| telnet {{ proxy_address }} {{ proxy_port }}"
#shell: "echo -e \"^]\\nclose\" | telnet `hostname` {{ proxy_port }}"
shell: "telnet `hostname` {{ proxy_port }}"
register: telnet_result
ignore_errors: yes
tags:
- giga
- debug: msg="telnet output result was = {{ telnet_result }}"

Running ansible-playbook using the following command, gives me the follwoing error (if I use either of the shell commands listed above).
PS: File myplaybook.yml is just calling a role mytask.
ansible-playbook -i inventory -l localhost myplaybook.yml --extra-vars "proxy_port=2878" -t giga -vvv
Output:

Besides, you seem like trying to mimic wait_for module.
