### Worker nodes

As of Beta 13, the worker nodes also have SSH enabled when connecting from
manager nodes. SSH access is not possible to the worker nodes from the public

The Linux worker nodes have SSH enabled. SSH access is not possible to the worker nodes from the public
Internet directly. To access the worker nodes, you will need to first connect to a
manager node (see above) and then `ssh` to the worker node, over the private
network. Make sure you have SSH agent forwarding enabled (see below). If you run
the `docker node ls` command you can see the full list of nodes in your swarm.
You can then `ssh docker@<worker-host>` to get access to that node.

Prepend the domain from `/etc/resolv.conf` to the returned `HOSTNAME` in
`docker node ls`.

$ docker node ls

##### Using SSH agent forwarding
##### Configuring SSH agent forwarding
SSH agent forwarding allows you to forward along your ssh keys when connecting from one node to another. This eliminates the need for installing your private key on all nodes you might want to connect from.

## Connecting to your Windows worker nodes using RDP
The Windows worker nodes have RDP enabled. RDP access is not possible to the worker nodes from the public
Internet. To access the worker nodes using RDP, you will need to first connect to a
manager node (see above) over `ssh`, establish a SSH tunnel and then use RDP to connect to the worker node over the SSH tunnel.
To get started, first login to a manager node and determine the private IP address of the Windows worker VM:
```
$ docker node inspect <windows-worker-node-id> | jq -r ".[0].Status.Addr"
```
Next, in your local machine, establish the SSH tunnel to the manager for the RDP connection to the worker. The local port can be any free port and typically a high value e.g. 9001.
```
$ ssh -L <local-port>:<windows-worker-ip>:3389 -p <manager-ssh-port> docker@<manager-ip>
```
Finally you can use a RDP client on your local machine to connect to `local-host`:`local-port` and the connection will be forwarded to the RDP server running in the Windows worker node over the SSH tunnel created above.
## Running apps
You can now start creating containers and services.
