rsync_to uses incorrect port when using Beaker with vagrant

[mjs510]

Using beaker with beaker-vagrant versions 0.6.7 and above, when I call rsync_to it attempts to connect to the guest on port 2222. This fails as the guest is not listening on that port.

Here is a typical error:

rsync: localhost:/data/ to root@10.255.137.136:/data {:ignore => ["spec", "tests", ".git", ".vagrant", "vagrant"]}
rsync returned #<Rsync::Result:0x000055fcd247dd60 @raw="ssh: connect to host 10.255.137.136 port 2222: Connection refused\r\nrsync: connection unexpectedly closed (0 bytes received so far) [sender]\nrsync error: unexplained error (code 255) at io.c(228) [sender=3.2.3]\n", @exitcode=255>

Note, vagrant is forwarding port 22 on the guest to 2222 on the host so rsync_to could successfully connect to localhost port 2222, but not 10.255.137.136 port 2222.

This problem only occurs when using beaker-vagrant versions higher than 0.6.7. I believe the port to use is determined from the ssh config (https://github.com/voxpupuli/beaker/blob/master/lib/beaker/host.rb#L579) so is it possible that this commit in beaker-vagrant has introduced a bug? 5cd6320
