Plays taking way to long to run...

Seeing a weird problem with running playbooks from my Macbook, which is running OS X 10.10.5… The plays are taking a very long time to run:

`
Wills-MacBook-Air:ist-ansible will$ ansible-playbook --version
ansible-playbook 2.3.0.0
config file = /Users/will/Downloads/my-ansible/ansible.cfg
configured module search path = Default w/o overrides
python version = 2.7.10 (default, Jul 14 2015, 19:46:27) [GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.39)]
Wills-MacBook-Air:ist-ansible will$ ansible-playbook -i prod -u root -k run_role.yml -e “ROLE=common” -e “TARGET=my-server”
SSH password:

As you may notice, the profiling of the plays that do stuff (as above) all are taking 2:33… Anyone know the problem offhand (DNS?)

Thanks,

Tested my role on an Ubuntu host running Ansible 2.3.0.0, same problem… So it wasn’t just my Macbook.

On a hunch, edited /etc/ssh/sshd_config on the target system, put in “UseDNS no”, and restarted sshd - reran on my Macbook, problem solved!

Thus confirming the age-old sysadmin haiku truth:

It’s not DNS
There’s no way it is DNS
It was DNS
