This was a stubborn one.
docker-machine --debug start dusty
This would hang with the following.
Testing TCP connection to: localhost:64623 Testing TCP connection to: localhost:64623 Testing TCP connection to: localhost:64623 ...
No problems connecting to
ssh localhost -p 64623.
No issues navigating to http://localhost:64623. I would see a page with the SSH server version.
The culprit was this entry in
/etc/hosts, from some experimentation on blocking ads via a hosts file.
The fix was to properly define
127.0.0.1 localhost ::1 localhost
I opened docker-machine#1946 to improve the error message here.
