Hi, I’m trying to switch from fireball to accelerate and getting a few issues. The first issue I’m getting is that it doesn’t appear to support the formatting of my hosts file that i’ve been using for months: [api] live-api2.xx ansible\_ssh\_host=11.22.33.44 private\_ip=22.33.44.55 private\_hostname=live-api2.internal.xx cron\_state=absent This generates the following error: fatal: [live-api2.xx] =\> host not found: 11.22.33.44 I’m able to work around the issue by replacing the line with: live-api2.xx private\_ip=22.33.44.55 private\_hostname=live-api2.internal.xx cron\_state=absent and ensuring the first part fully resolves (Before this was not an issue) The second problem is that the playbook then fails on: live-api2.xx (reason: keyczar is not installed). This leads me to believe that the variable: ansible\_python\_interpreter: /root/.virtualenvs/ansible/bin/python defined in the vars: section of the playbook is not working as I expect. I can work around the issue probably by just installing python-keyczar in the base python rather than a virtualenv Cheers, Tom ---

Could you open up a github issue for the first problem? That one is especially odd, since the python documentation clearly states that when an IP address is used it should not result in a DNS lookup. For the second, you should be able to verify the daemon’s interpreter by looking at the output of “ps aux | grep python”, as the daemon should be started with the same interpreter. ---

Benno (@bennojoy) tracked down the first issue and I just merged in his fix for this, if you’d like to give it a try. ---

Hi Tom, Can you confirm whether you fixed that by installing keyczar there on the local or remote end? I’d expect exactly that for the local end. Thanks! ---

Hello, I’ve problems with accelerate mode too. I’m unable to use in any of my servers. I have installed kyczar in both (local and remote) and always ansible returns the same error: PLAY [ansibletest] \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* GATHERING FACTS \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* fatal: [ansibletest] =\> python-keyczar must be installed to use fireball/accelerated mode Regards! ---

Are you also installing in a virtualenv? ---

No, the python-\* packages are installed globally in the system via apt-get. Ansible uses openssh to connect to servers. ---

“Ansible uses openssh to connect to servers.” And also accelerate mode, in your case above. Please make sure it’s available on your local host too. You might be using ansible\_python\_interpreter and it’s not available in that Python. Perhaps not. In either case, maybe hop on IRC and we can help figure it out.
