A couple errors have recently cropped up when using Ansible, and the latest is causing me to not be able to use it at all. I tried searching for the fatal error(s), but was not able to find anythin mysef, I’m hopeful that this forum can help me out. My OS is RHEL 6.4 and it also pulls packages from EPEL. My ansible is “ansible 1.5.5” from EPEL. **Command:** > ANSIBLE\_SSH\_ARGS=“” ansible-playbook -T 30 -c ssh -s -K -i ~/my\_ansible\_inventory.txt -l [labadmin.lab.boomi.com](http://labadmin.lab.boomi.com) --tags zabbix-agent /etc/ansible/site.yml The first warning message I have been able to find documented elsewhere, and I think it is not related to the fatal error. **Warning:** > /usr/lib64/python2.6/site-packages/pycrypto-2.6.1-py2.6-linux-x86\_64.egg/Crypto/Util/number.py:57: PowmInsecureWarning: Not using mpz\_powm\_sec. You should rebuild using libgmp \>= 5 to avoid timing attack vulnerability. > > \_warn(“Not using mpz\_powm\_sec.

Correct, the warning message can be ignored, and there is a configuration setting (system\_warnings in your ansible.cfg) that can be set to “False” to disable it. The fatal error appears to be reporting that the executable you’re trying to call via the pipe lookup is not being found at the path specified. Can you share what that is, and validate that the binary is there and executable by the user that the play is running with to make sure there are no security issues? ---

Thanks for your response. Sorry for not being sure… But you’re saying I’m calling an executable via a pipe lookup … And I have no idea what that means. I’m certainly not doing it intentionally. You ask me to validate “the binary is there” but I don’t know what binary to look for. Is this happening during the “Gathering Facts” or afterward? Is the error happening on the local side or the remote side? ---

Did you download a role from Galaxy or somewhere else? From the output of the error, it looks like somewhere in your play this appears: ```auto {{ lookup('pipe','some_executable_name_here') }} ``` So you may want to grep for ‘lookup’ or ‘pipe’ in your files. ---

I copied some code from some place (which previously worked). My code does not have the word “pipe” anywhere. The only part that has “lookup” is here: - name: Configure ansible users SSH key authorized\_key: user=ansible key=“{{ lookup(‘file’, ‘/etc/ansible/roles/common/files/ansible-id\_rsa.pub’) }}” tags: ansible-user-setup But that tag shouldn’t be called when I use “–tags zabbix-agent”. Also that particular file is set permissions 644. ---

What about a “with\_pipe” ? Did you check both the templates and the playbooks? It seems to be in a template. ---

Thanks all. I was finally able to narrow the error down to this variable file /etc/ansible/roles/common/vars/main.yml ---

datestamp: “{{ lookup(‘pipe’, ‘date +%Y%m%d-%H%M%S’) }}” That should be the updated syntax for what you are trying to do. ---

it seems like you are doing a lookup with pipe and the program you are calling cannot be found. ---

Generally we consider any traceback like the above to be a bug, regardless of the cause, so please do open a github issue for this. Beyond that, as Brian mentioned, apparently it’s having trouble executing the date command as it is specified. I tested the above syntax with this small playbook: $ cat test\_pipe\_date.yml - hosts: localhost connection: local gather\_facts: no vars: datestamp: “{{ lookup(‘pipe’, ‘date +%Y%m%d-%H%M%S’) }}” tasks: - debug: var=datestamp And it worked as expected (with the current devel branch): TASK: [debug var=datestamp] \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* ok: [127.0.0.1] =\> { “datestamp”: “20140606-204031” } So this appears to be something specific to your platform or environment.
