Hi Community, I’m facing some very basic problem. I’m trying to run open telnet session with a device. However, when I’m filling the port dynamically using jinja template, the port is passed as unicode thus I get the following error: error: getaddrinfo() argument 2 must be integer or string This is my playbook, check how the port is assigned. Please note that when Ansible pass on the port value it will use ‘unicode’ type rather than integer or string thus getaddrinfo failes: ` - hosts: all connection: local gather\_facts: no vars: nodes: “{{ node\_list }}” tasks: - name: telnet emulator telnet: host: 10.8.120.141 send\_newline: yes port: “{{ item.console|int }}” user: myuser password: mypassword login\_prompt: "localhost login: " password\_prompt: "Password: " prompts: - “[~#]” command: - ls loop: “{{ nodes|flatten(levels=1)|default() }}” when: item.node\_type == ‘qemu’ ` This is the inventory file: ` 10.8.120.141 ` This is how I run the play: ` ansible-playbook -vvvv --extra-vars “node\_list=[{‘node\_type’:‘qemu’,‘console’:5022},{‘node\_type’:‘qemu’,‘console’:5002},{‘node\_type’:‘qemu’,‘console’:5004},{‘node\_type’:‘qemu’,‘console’:5020}]” telnet.yaml -i inventory ` And this is the error I get: ` # ansible-playbook -vvvv --extra-vars “node\_list=[{‘node\_type’:‘qemu’,‘console’:5022},{‘node\_type’:‘qemu’,‘console’:5002},{‘node\_type’:‘qemu’,‘console’:5004},{‘node\_type’:‘qemu’,‘console’:5020}]” telnet.yaml -i inventory ansible-playbook 2.7.10 config file = None configured module search path = [u’/root/.ansible/plugins/modules’, u’/usr/share/ansible/plugins/modules’] ansible python module location = /usr/lib/python2.7/site-packages/ansible executable location = /usr/bin/ansible-playbook python version = 2.7.5 (default, Nov 20 2015, 02:00:19) [GCC 4.8.5 20150623 (Red Hat 4.8.5-4)] No config file found; using defaults setting up inventory plugins /tmp/inventory did not meet host\_list requirements, check plugin documentation if this is unexpected /tmp/inventory did not meet script requirements, check plugin documentation if this is unexpected Parsed /tmp/inventory inventory source with ini plugin Loading callback plugin default of type stdout, v2.0 from /usr/lib/python2.7/site-packages/ansible/plugins/callback/default.pyc PLAYBOOK: telnet.yaml \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* 1 plays in telnet.yaml PLAY [all] \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* META: ran handlers TASK [telnet emulator] \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* task path: /tmp/telnet.yaml:12 The full traceback is: Traceback (most recent call last): File “/usr/lib/python2.7/site-packages/ansible/executor/task\_executor.py”, line 106, in run item\_results = self.\_run\_loop(items) File “/usr/lib/python2.7/site-packages/ansible/executor/task\_executor.py”, line 343, in \_run\_loop res = self.\_execute(variables=task\_vars) File “/usr/lib/python2.7/site-packages/ansible/executor/task\_executor.py”, line 612, in \_execute result = self.\_handler.run(task\_vars=variables) File “/usr/lib/python2.7/site-packages/ansible/plugins/action/telnet.py”, line 61, in run tn = telnetlib.Telnet(host, port, timeout) File “/usr/lib64/python2.7/telnetlib.py”, line 211, in **init** self.open(host, port, timeout) File “/usr/lib64/python2.7/telnetlib.py”, line 227, in open self.sock = socket.create\_connection((host, port), timeout) File “/usr/lib64/python2.7/socket.py”, line 553, in create\_connection for res in getaddrinfo(host, port, 0, SOCK\_STREAM): error: getaddrinfo() argument 2 must be integer or string fatal: [10.8.120.141]: FAILED! =\> { “msg”: “Unexpected failure during module execution.”, “stdout”: “” } to retry, use: --limit @/tmp/telnet.retry PLAY RECAP \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* 10.8.120.141 : ok=0 changed=0 unreachable=0 failed=1 ` I’ve added print(type(port)) to /usr/lib/python2.7/site-packages/ansible/plugins/action/telnet.py file.

All template results default to unicode strings, this is something Jinja2 does by default., but this is probably something we should fix in the telnet plugin by forcing port to always be an int. I'm unsure why telnet lib does not take a 'unicode string' as a 'string'. ---

Hi Brian, Any WA for the meantime? At the moment, I’m unable to use telnet module. Doron ---
