Hi, I have a rare behavior reported earlier, and I want to share it in case a third person encounters it. This behavior appeared misteriously in previously working code, and it causes ansible to ssh into the localhost running the playbook. The error I got was "Authentication failed!"
I fixed it, and it behaves the same as the issue reported here: https://github.com/ansible/ansible/issues/3174 . This issue was closed because of non-reproducible case. I do not have any repo steps, but I have more detail. Here is the task: - name: Generate public key from private key sudo: no delegate_to: 127.0.0.1 command: 'ssh-keygen -y -f ../config/ssh/{{sshkey}}' register: pubkeyresult changed_when: false Here is the -vvvv from that task: TASK: [boxprep | Generate public key from private key] ************************ <127.0.0.1> ESTABLISH CONNECTION FOR USER: azureuser <127.0.0.1> EXEC ['sshpass', '-d12', 'ssh', '-tt', '-vvv', '-o', 'ControlMaster=auto', '-o', 'ControlPersist=60s', '-o', 'ControlPath=/home/xxx/.ansible/cp/ansible-ssh-%h-%p-%r', '-o', 'StrictHostKeyChecking=no', '-o', 'Port=22', '-o', 'GSSAPIAuthentication=no', '-o', 'PubkeyAuthentication=no', '-o', 'User=prepuser', '-o', 'ConnectTimeout=10', '127.0.0.1', "/bin/sh -c 'mkdir -p $HOME/.ansible/tmp/ansible-1385089465.95-27966096848090 && chmod a+rx $HOME/.ansible/tmp/ansible-1385089465.95-27966096848090 && echo $HOME/.ansible/tmp/ansible-1385089465.95-27966096848090'"] fatal: [vgrid01] => Authentication failure. It looks like its trying to ssh into 127.0.0.1 with a user account that is only on the target machine. My inventory looks like this: [boxprep] vgrid01 ansible_ssh_host=myhost ansible_ssh_user=preconfiguser ansible_ssh_pass=myhostpassword [hdpsolos] vgrid01 ansible_ssh_host=myhost ansible_ssh_user=postconfiguser ansible_ssh_private_key=../path/to/preconfiguration_private_key After I found the original report, I grepped for "ansible_connection" and found it in some group_vars for [hdpsolos]. I commented out the line and delgate_to started working again: TASK: [boxprep | Generate public key from private key] ************************ <127.0.0.1> EXEC ['/bin/sh', '-c', 'mkdir -p $HOME/.ansible/tmp/ansible-1385090296.49-167490580878593 && chmod a+rx $HOME/.ansible/tmp/ansible-1385090296.49-167490580878593 && echo $HOME/.ansible/tmp/ansible-1385090296.49-167490580878593'] <127.0.0.1> REMOTE_MODULE command ssh-keygen -y -f ../config/ssh/preconfig.key <127.0.0.1> PUT /tmp/tmpE2RcBw TO /home/xxx/.ansible/tmp/ansible-1385090296.49-167490580878593/command <127.0.0.1> EXEC ['/bin/sh', '-c', '/usr/bin/python /home/xxx/.ansible/tmp/ansible-1385090296.49-167490580878593/command; rm -rf /home/xxx/.ansible/tmp/ansible-1385090296.49-167490580878593/ >/dev/null 2>&1'] ok: [vgrid01] => {"changed": false, "cmd": ["ssh-keygen", "-y", "-f", "../config/ssh/preconfig.key"], "delta": "0:00:00.029258", "end": "2013-11-21 19:18:16.650485", "item": "", "rc": 0, "start": "2013-11-21 19:18:16.621227", "stderr": "", "stdout": "ssh-rsa ideletedthepubkeyfromthisoutput", "stdout_lines": ["ssh-rsa ideletedthepubkeyfromthisoutput"]} If I uncomment the "ansible_connection: ssh" line, the local_action starts failing again. This code has worked for weeks and weeks. Now it failed. Further, the playbook running the task operated against [boxprep] but was affected by the setting in [hdpsolo]'s group_vars. I don't really need the ansible_connection: ssh value, it was a leftover from my inexperience with ansible. So I'm good to go, but maybe this will help someone in the future. I recommend greping your entire working directory to find the setting. I had forgotten ever using it. -g -- You received this message because you are subscribed to the Google Groups "Ansible Project" group.
