routeros_command – fails with timeout on devices with long identity string #58325

Closed heuels closed 4 years ago

heuels commented 5 years ago
SUMMARY

As reported by @danrimal, @moosehead123 in #53199, when device's identity is greater than 24 characters the request fails with timeout.

Hello, I can also hit this bug, but in my case, maximal working identity is 24 chars. Longer mikrotik identity doesn't work and ending with timeout.

ansible 2.7.9

Hi,

I've also run into this bug. It seems to happen when the overall length of the prompt is greater than 41 characters. In other words, the longer the username, the shorter the identity can be.

Ansible 2.8.0

TEMPORARY WORKAROUND

You can add +cet512w to your username in hosts file, this makes the default terminal width equal to 512 cols and enables "dumb" terminal mode.

Your final host definition should look something like this:

---
example_routeros:
    ansible_host: 192.168.88.1
    ansible_user: admin+cet512w
    ansible_ssh_pass: ''
    ansible_network_os: routeros
    ansible_connection: network_cli

I also noticed that the routeros_command module will have the commands echoed a few times in the registered stdout data if the command is to long. Applying the above mentioned workaround also fixes that behavior.

This also exists on routeros_facts.

For reference, the +cet512w flag can be added onto the ansible-playbook command like so: -k +cet512w

heuels commented 4 years ago

This also exists on routeros_facts.

Yes, that's true since both modules use the same connection mechanism.

eduardomazolini commented 4 years ago

Same for me. user@domain is my user from Radius user@domain+cet512w not work for me.
