Ansible : SSH Error: ControlPath too long

I run a computer with Ubuntu 15.10 and I try to run Vagrant with Ansible.

Before start, I like to say that I don't have any idea about server management and especialy the Ansible.

The reason I am going to run my system this way, is because I have start working on a project that requires this installation.

After all, the problem I have is that while provisioning the Vagrant I get the following message

<aaa.dev> ESTABLISH CONNECTION FOR USER: vagrant
<aaa.dev> REMOTE_MODULE setup
<aaa.dev> EXEC ssh -C -tt -vvv -o UserKnownHostsFile=/dev/null -o IdentitiesOnly=yes -o IdentityFile=/media/merianos/Large Internal/Vagrant/ansible-project/.vagrant/machines/default/virtualbox/private_key -o ForwardAgent=yes -o ControlMaster=auto -o ControlPersist=60s -o ControlPath="/home/merianos/.ansible/cp/%h-%r" -o StrictHostKeyChecking=no -o KbdInteractiveAuthentication=no -o PreferredAuthentications=gssapi-with-mic,gssapi-keyex,hostbased,publickey -o PasswordAuthentication=no -o User=vagrant -o ConnectTimeout=30 aaa.dev /bin/sh -c 'mkdir -p $HOME/.ansible/tmp/ansible-tmp-1446622406.54-199921739516776 && chmod a+rx $HOME/.ansible/tmp/ansible-tmp-1446622406.54-199921739516776 && echo $HOME/.ansible/tmp/ansible-tmp-1446622406.54-199921739516776'
fatal: [aaa.dev] => SSH Error: ControlPath too long
It is sometimes useful to re-run the command using -vvvv, which prints SSH debug output to help diagnose the issue.

So, is it posible to help me someone with this issue ?

Just to say that I have try this article : https://github.com/ansible/ansible/issues/11536 and I changed the control_path in my ansible.cfg to control_path = %(directory)s/%%h-%%r but still not working.

Note My installation path contains a space that I can't remove it because are running many other projects on the same HDD and the configuration will be huge for all the projects. I don't know if that space is the problem, but just I say about it.

UPDATE #1

Result before I change anything:

<aaa.dev> ESTABLISH CONNECTION FOR USER: vagrant
<aaa.dev> REMOTE_MODULE setup
<aaa.dev> EXEC ssh -C -tt -vvv -o UserKnownHostsFile=/dev/null -o IdentitiesOnly=yes -o IdentityFile=/media/merianos/Large Internal/Vagrant/ansible-project/.vagrant/machines/default/virtualbox/private_key -o ForwardAgent=yes -o ControlMaster=auto -o ControlPersist=60s -o ControlPath="/home/merianos/.ansible/cp/ansible-ssh-%h-%p-%r" -o StrictHostKeyChecking=no -o KbdInteractiveAuthentication=no -o PreferredAuthentications=gssapi-with-mic,gssapi-keyex,hostbased,publickey -o PasswordAuthentication=no -o User=vagrant -o ConnectTimeout=30 aaa.dev /bin/sh -c 'mkdir -p $HOME/.ansible/tmp/ansible-tmp-1446628138.53-155680153347939 && chmod a+rx $HOME/.ansible/tmp/ansible-tmp-1446628138.53-155680153347939 && echo $HOME/.ansible/tmp/ansible-tmp-1446628138.53-155680153347939'

Result with control_path = %(directory)s/%%h-%%r :

UPDATE #2

After I set the ssh_args = -o ControlMaster=off I get the following result:

<aaa.dev> ESTABLISH CONNECTION FOR USER: vagrant
<aaa.dev> REMOTE_MODULE setup
<aaa.dev> EXEC ssh -C -tt -vvv -o UserKnownHostsFile=/dev/null -o IdentitiesOnly=yes -o IdentityFile=/media/merianos/Large Internal/Vagrant/ansible-project/.vagrant/machines/default/virtualbox/private_key -o ForwardAgent=yes -o ControlMaster=auto -o ControlPersist=60s -o ControlPath="/home/merianos/.ansible/cp/ansible-ssh-%h-%p-%r" -o StrictHostKeyChecking=no -o KbdInteractiveAuthentication=no -o PreferredAuthentications=gssapi-with-mic,gssapi-keyex,hostbased,publickey -o PasswordAuthentication=no -o User=vagrant -o ConnectTimeout=30 aaa.dev /bin/sh -c 'mkdir -p $HOME/.ansible/tmp/ansible-tmp-1446628489.4-10074395967553 && chmod a+rx $HOME/.ansible/tmp/ansible-tmp-1446628489.4-10074395967553 && echo $HOME/.ansible/tmp/ansible-tmp-1446628489.4-10074395967553'

In general for each modification I did, the error message seems to be the same, and maybe the configuration it happens from some other level, but not the ansible.cfg.

Unfortunatelly I don't know where to find that location :(

回答1:

I described the problem in similar question.

You need to change it to something shorter (if you have long hostname). For test case you can try just ./master, but for real use case, you should use at least ./s/%%h-%%r.

回答2:

The very first sentence of the documentation for OpenSSH specific settings in Ansible says:

Under the [ssh_connection] header, the following settings are tunable for SSH connections.

So you need to place the ssh_args variable in [ssh_connection] section of the ansible.cfg, for example:

[defaults]
timeout = 600

[ssh_connection]
ssh_args = -o ControlMaster=off

In fact overriding the ssh_args with an empty value disables the defaults for ControlMaster/ControlPersistent/ControlPath in Ansible, so it should simply be:
