    Hi,

    Great to be part of this community.

    We are writing ansible playbook to manage Aruba CX switches. However, we the playbook get the output of commands when switch is connected to a jump host.

    Our environment -

    [Ansible Execution Host] -> Jump Host -> Switch

    The playbook times out with following error -

    "msg": "socket_path does not exist or cannot be found.\nSee the socket_path issue category in Network Debug and Troubleshooting Guide"​


    Traceback -

    The full traceback is:
      File "/tmp/ansible_arubanetworks.aoscx.aoscx_command_payload_zt3y_wa1/ansible_arubanetworks.aoscx.aoscx_command_payload.zip/ansible_collections/arubanetworks/aoscx/plugins/module_utils/aoscx.py", line 447, in run_commands
        return conn.run_commands(commands=commands, check_rc=check_rc)
      File "/tmp/ansible_arubanetworks.aoscx.aoscx_command_payload_zt3y_wa1/ansible_arubanetworks.aoscx.aoscx_command_payload.zip/ansible/module_utils/connection.py", line 184, in __rpc__
        response = self._exec_jsonrpc(name, *args, **kwargs)
      File "/tmp/ansible_arubanetworks.aoscx.aoscx_command_payload_zt3y_wa1/ansible_arubanetworks.aoscx.aoscx_command_payload.zip/ansible/module_utils/connection.py", line 138, in _exec_jsonrpc
        raise ConnectionError('socket_path does not exist or cannot be found.'

    However, same playbook works when executed on the Jump Host.

    What might be the problem?

    Thanks
    Ratnesh

    Hi,

    Do you have look https://docs.ansible.com/ansible/latest/network/user_guide/network_debug_troubleshooting.html#troubleshooting-socket-path-issues

    May be also also on aruba ansible-collection github ?

    PowerArubaCP: Powershell Module to use ClearPass API (create NAD, Guest...)

    PowerArubaCL: Powershell Module to use Aruba Central

    PowerArubaCX: Powershell Module to use ArubaCX API (get interface/vlan/ports info)..

    Hello Ratnesh,

    have you managed to get this to work? I have the same setup as you and I'm experiencing the same issue. The sockets are being created on the Ansible host, but the playbook is basically in a loop and then fails because the sockets are timing out.

    Hi kg36,

    No, couldn't get it working. Luckily, galaxy collection for Aruba works for Aruba CX also so we used that as a workaround.

    Hello,

    thank you for the response. Which galaxy collection are you talking about? The Aruba OS-Switch collection? https://galaxy.ansible.com/arubanetworks/aos_switch

    We are mainly after the aoscx_command module to get a readable config. The API modules for CX are working for us, but the SSH modules aren't.

    I have managed to get this working using the community aruba_command module (https://docs.ansible.com/ansible/latest/collections/community/network/aruba_command_module.html). This works with an SSH connection over a jump host, but the official Aruba module/collection doesn't.

    Here is a sanitized playbook:

     - name: "Backup ArubaOS-CX as CLI"
       hosts: aruba_oscx_ssh
       gather_facts: no
       strategy: free
       collections:
         - community.network
    
       tasks:
    
        - name: "Get hostname from running-config"
          when: ansible_network_os is defined and ansible_network_os == "arubanetworks.aoscx.aoscx"
          aruba_command:
            commands:
              - show running-config | include hostname
          register: hostname
    
        - name: "Change hostname variable"
          when: ansible_network_os is defined and ansible_network_os == "arubanetworks.aoscx.aoscx"
          set_fact:
            hostname: "{{ hostname.stdout[0] | regex_replace('.*\\s','') | regex_replace('\\\"','') }}"
    
        - name: "Copy running-config to local as CLI"
          when: ansible_network_os is defined and ansible_network_os == "arubanetworks.aoscx.aoscx"
          aruba_command:
            commands:
              - show running-config
          register: backupinfo
    
        - name: "Save backup info to file"
          when: ansible_network_os is defined and ansible_network_os == "arubanetworks.aoscx.aoscx"
          copy:
            content: '{{ backupinfo.stdout[0] }}'
            dest: "/tmp/aruba/switches/{{ hostname }}_cli"
    ​

    And here the variables for the host itself:
    [aruba_oscx_ssh:vars]
    ansible_connection=ansible.netcommon.network_cli
    ansible_network_os=arubanetworks.aoscx.aoscx
    ​

    Hope this helps someone in the future.

    Hi, in the aoscx collection it's only aoscx_config and aoscx_command which are using ssh. Everything else are using the API and you need to use a reverse http proxy to get jump host functionality.

    I am aware of how to use it, but the modules do not work via a jump host. The actual Ansible host can SSH to the devices just fine. The API modules, over the jump host, which is also the reverse proxy, also work. It is simply the combination of Ansible SSH modules + jump host that doesn't work.

    Maybe there is a ProxyCommand option for the SSH modules, but I don't know it. The API connection has the ansible_aoscx_use_proxy setting, but that's not relevant to the SSH connection.

    Have you tried to configure your jump host in the .ssh/config file? And using ssh-key for auth on the jump host?
    Host jmp
       User username
       Hostname jmp.example.com
       IdentityFile ~/.ssh/id_rsa
    
    Host cx-sw.example.com
       ProxyJump jmp
       
    Host 172.16.1.*
       ProxyJump jmp​

    As I said:

    "The actual Ansible host can SSH to the devices just fine. The API modules, over the jump host, which is also the reverse proxy, also work. It is simply the combination of Ansible SSH modules + jump host that doesn't work."
