network differences resulting in test failures

[Trott]

Network settings for test-rackspace-ubuntu1604-x64-1 and test-rackspace-ubuntu1604-x64-2 appear to be different, or at least I'm inferring that from the fact that the nightly internet test runs fail on test-rackspace-ubuntu1604-x64-2 but succeed on test-rackspace-ubuntu1604-x64-1.

Here's what a failure looks like:

The difference in /etc/hosts is that -2 has its ipv6, ipv4 and intranet ip addresses listed as resolving to its own hostname whereas -1 doesn't. I've manually added in the entries for -1. 🤞

I'm going to optimistically close this. I usually watch node-daily-master closely enough that if this didn't fix it, I'll notice and re-open. Thanks, @rvagg!

This issue is stale because it has been open many days with no activity. It will be closed soon unless the stale label is removed or a comment is made.

Going to close this since it looks like its not recreated again for a long time.
