update arm jump host proxycommand

[rvagg]

Updating the jump host command, -W isn't working anymore due to some restrictions I've placed on the jump host but nc will work just fine now. Further to #1889.

This is not replacing {{ ansible_ssh_private_key_file }} in the .ssh/config output of playbooks/write-ssh-config.yml and hasn't been for a while but I don't know why. Would appreciate some help tracking this down if someone has time.

LGTM

Worked on the two release raspberry pis but not release-requireio-osx1010-x61-1

I'm checking this. Can someone confirm this is correct way to work-around the ansible bug:

s%{{ ansible_ssh_private_key_file }}%\~/ssh/nodejs_build_test%

[mhdawson]

I believe so I just have:

ProxyCommand ssh -i ~/.ssh/nodejs_build_release -p 2222 [email protected] nc -q0 %h %p

[sam-github]

@mhdawson Its a bit more complicated, the key that is substituted in has to be either ~/.ssh/nodejs_build_release or ~/.ssh/nodejs_build_test depending on the host... :-(. I guess that's why it would be good if ansible did this correctly, it should have that knowlege. I don't ATM have the time to do the context sensitive replacement (manually, with a script, or with ansible).

I investigated this a bit but wasn't able to take it all the way: #1483

Works perfectly with Ansible 2.4.

[sam-github]

OK, so it would be better to use ansible 2.4? We should mention that in the README -- I wonder if some of the warnings I see from ansible-playbook are because I'm using an ansible version that doesn't match the one the playbooks were developed for.

I avoid running it on my Mac these days where Python 3 is available and the Ansible that ships with brew has that baked in. I run from my Linux box which is still defaulting to Python 2. There's a bunch of other niggles in here that cause problems.

See #1399 for the stalled effort to address this. Someone needs to take this over.
