Description

Have you ever wished you could remotely access your server's admin console without having to setup a complex remote access system? Now you can with SSHD.

SSHD securely exposes your bukkit admin console using the SSH protocol - the same protocol that serves as the secure foundation for nearly all remote server administration.

  • Compatible with all ssh clients, regardless of operating system.
  • Remotely view your server log in real-time.
  • Remotely issue commands from the server console, just as if you were on the server itself.
  • Supports multiple concurrent remote connections.
  • Strong identity support using public key authentication.
  • Remotely script your server by issuing one-off console commands with ssh.

Why should I use SSHD?

  • Your server runs on Windows.
  • You are in a shared hosting environment that only gives you access to the log files.
  • You want to share access to your server console, but don't want to give anybody access to the machine its running on.
  • You always wanted to use RCON, but want to see the server log as well.
  • You are tired of running your server in a Screen session.
  • You just want to access your server console using SSH.

Configuration

  • listenAddress - The network interface(s) SSHD should listen on. Default all
  • port - Specify the port SSHD should listen on. Default 22
  • username/password - The credentials used to log into the server console. Default blank

Note: By default, only public key authentication is enabled. This is the most secure authentication mode! Setting a username and password will make your server less secure.

Setting Up Public Key Authentication

Setting up public key authentication with SSH requires first generating a public and private key pair and then installing just the public key on your Bukkit server.

On Windows

1. Download PuttyGen
2. Use PuttyGen to create a new public/private key pair. Here is a tutorial video.
- Make sure to set a key passphrase
- Make sure your key type is SSH-2 RSA
- Save the public key with your login name
- Save the private key in a secure location
3. Copy the public key to the authorized_keys directory in the SSHD plugin directory.
- Make sure the public key file name matches the user name you want to log in with. Remove the file extension.

On Linux/OS X

1. Check to see if you have an existing ssh key
- $ ls -al /.ssh
- If you get a directory not found error or an empty list, go to step 2, otherwise go to step 3
2. Create your SSH public/private key pair.
- $ ssh-keygen -t rsa
- - Press Enter to accept the default path (.ssh\id_rsa)
- - Set a passphrase
- $ eval "$(ssh-agent -s)"
- $ ssh-add /.ssh/id_rsa
3. Export your SSH public key in PEM format.
- $ ssh-keygen -ef /.ssh/id_rsa > your_username
- replace your_username with your Minecraft login name
4. Copy the your_username file to the authorized_keys directory in the SSHD plugin directory.

Commands

None - just install and go.

Permissions

None - SSHD uses cryptographic certificates or a secure username and password to verify remote access.
