## Common questions

### How can I access the PuTTY GUI in the Docker container?

You can open the full graphical interface from any modern web browser without client-side installation, or connect with any VNC client.

### Which port is used in the quick start example?

The quick start Docker command maps host port 5800 to container port 5800.

### Where should the container's data be stored?

The quick start example mounts a host directory, such as /docker/appdata/putty, to /config inside the container as read/write.

### What common PuTTY problems does the troubleshooting page cover?

It covers non-English filenames appearing as ?????? and idle SSH connections dropping.

### How does PuTTY detect a redirected SSH connection?

PuTTY uses server host keys to identify servers. Once it knows a server's host key, it can detect if an attacker redirects the connection to another machine.
