TCP Connection to SSH ip/port failed

[rhys.jame...@googlemail.com]

Hello,

I'm trying out packer for the first time. I am having difficulty getting ssh to work. I have run packer in debug mode and the following lines are output explaining why I cannot ssh to my target;

2017/11/02 16:51:20 packer: 2017/11/02 16:51:20 [DEBUG] TCP connection to SSH ip/port failed: dial tcp 192.168.47.110:4439: getsockopt: connection refused
2017/11/02 16:51:25 packer: 2017/11/02 16:51:25 [DEBUG] TCP connection to SSH ip/port failed: dial tcp 192.168.47.110:4439: getsockopt: connection refused
2017/11/02 16:51:30 packer: 2017/11/02 16:51:30 [DEBUG] TCP connection to SSH ip/port failed: dial tcp 192.168.47.110:4439: getsockopt: connection refused

The ip address is correct but the port is wrong. I have set ssh_host to  192.168.47.110 and ssh_port to 22. Is ssh_port being ignored or is it not intended for this?

Here is my packet file edited for understanding...

{
  "variables": {
    ...
    "ip_address": "192.168.47.110",
    ...
  },
  "builders": [{
      "boot_command": [
        "..."
      ],
       ....
      "ssh_host": "{{ user `ip_address` }}",
      "ssh_username": "{{ user `ssh_username` }}",
      "ssh_password": "{{ user `ssh_password` }}",
      "ssh_port": 22,
      ....
      "vboxmanage": [
            [
              "modifyvm",
              "{{.Name}}",
              "--nic1",
              "hostonly",
              "--hostonlyadapter1",
              "vboxnet0"
            ]
        ]
  }]
}

I have verified I can ssh into my host with...

ssh 192.168.47.110

Cheers,

Rhys

VirtualBox network is a bit quirky. By default packer sets up nat for ssh. So by default it ssh to 127.0.0.1:<random port> where this is NAT'ed to the guest IP port 22. If you want to suppress this see

https://www.packer.io/docs/builders/virtualbox-iso.html#ssh_skip_nat_mapping

But if you are just learning Packer I would recommend that you instead remove ssh_address and let packer handle that.

Removing ssh_address didn't work. I guess this is because I am settign a fix ip address. Settings ssh_skip_nat_mapping did the trick though.

Thanks,

Rhys
