Waiting for SSH - it appears the SSH connect/retry loop is not behaving properly

[Kevin Hannan]

Here is a link to a Gist that contains the packer template, vars file, kickstart, console and debug log.

Thanks for the extra pair of eyes on this.

This is a portion of the packer debug log for a run I just made.  Notice the 'Attempt SSH connection....' tries about every 7 seconds for 7 attempts then hangs.

Connection attempts are made from 10:07:19 to 10:08:32 then no more.

The SSH timeout is 7 minutes..  I stopped the log tail at 10:14:40 which was past the 7 minutes.  Packer should have terminated the connection loop at 7 minutes and failed the build.  But packer is blocked at this point.  I checked again at 10:23:17 just in case the initial check was too close to the 7 minute mark.  Even 15 minutes later it was still blocked.

The full log in the gist above shows the connection attempt was made only once before blocking.  Note the last log entry was 00:44:19 while I terminated the log tail at 09:10:53 - which is well beyond the 7 minute mark.

Thanks Rickard that fixed it. I guess I missed the note about removing the plugins... I upgraded from something like 0.8.12 all the way to current. Must have skipped the notes at 0.9...

Thanks again,
