Hi, Everyone.
I'm trying to run an Ansible playbook on two servers, and occasionally either one or both of them fail a task with the error "/usr/bin/python: can't open file 'command': [Errno 13] Permission denied". I started looking into why this was happening (and why it was only happening some of the time). I traced the error to the temporary directory where Ansible copies its command file sometimes being empty instead of the normal random directory created in /tmp (runner/__init__.py:Runner._make_tmp_path()). Looking into it further, it looks like sometimes the mkdir && echo command used to create the temporary directory is assumed to be successful, but the output, which should be the created directory, is empty (runner/connection_plugins/ssh.py:Connection._communicate()).
The mkdir && echo commands looks identical to me:
But when I print out the stderr output from the commands, they are very different:
Server 1 (failed):
Server 2 (ok):
I'm not familiar with SSH, so I don't understand much what's going on in the failing case. It looks to me like it's trying out different authentication methods, and eventually is successful. (For authentication, I have keys set up in authorized_keys in both servers.)
Version info:
control:
CentOS release 6.6 (Final)
Python 2.7.3
openssh.x86_64 5.3p1-104.el6
server1:
CentOS release 6.2 (Final)
Python 2.6.6
openssh.x86_64 5.3p1-70.el6
server2:
CentOS release 6.2 (Final)
Python 2.6.6
openssh.x86_64 5.3p1-70.el6
I hope someone could shed some light on this, or at least be able to propose a workaround, so I could get it to work.

I'm not familiar with SSH, so I don't understand much what's going on in the failing case. It looks to me like it's trying out different authentication methods, and eventually is successful. (For authentication, I have keys set up in authorized_keys in both servers.)

I hope someone could shed some light on this, or at least be able to propose a workaround, so I could get it to work.

Hey again.
As a workaround, I have now decided to force Ansible to use Paramiko instead of OpenSSH, and my playbooks work.
