+Spigot-SSHD
 ===========

-[![Build Status](https://travis-ci.org/rmichela/Bukkit-SSHD.png)](https://travis-ci.org/rmichela/Bukkit-SSHD)
+[![Build Status](https://travis-ci.org/Justasic/Spigot-SSHD.svg?branch=master)](https://travis-ci.org/Justasic/Spigot-SSHD)

-An SSHD daemon embedded in a Bukkit plugin.
+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 Spigot 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.
+- Audit history who is running commands in the console
+- Run Spigot without using screen or tmux (by adding `-noconsole`)
+- Remotely script your server by issuing one-off console commands with ssh.
+
+### Why should I use SSHD?
+
+- 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 GNU screen or tmux session.
+- You just want to access your server console using SSH.
+
+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 Spigot server. This plugin supports all modern SSH key algoritms as OpenSSH. You can paste as many public keys from the methods below into each user's authorization file if they have multiple private keys. You can read [this guide from ssh.com](https://www.ssh.com/ssh/keygen/) if you want a better explanation on different key files.
+
+## Generating New Keys
+
+#### On Windows
+
+1. Ensure [Putty](https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html) is installed and open up `puttygen` (you can search for it in start search).
+2. Click `Generate` and follow the directions.
+3. When it finishes, set your key comment (if you like) and copy the text from the big `Public key for pasting into OpenSSH authorized_keys file`
+4. Create a new file inside of the `plugins/SSHD/authorized_users` folder and name the file just the username (example: `justasic`, there should ***NOT*** be a file extension or authentication does not work).
+5. Paste the key you copied from step 3 into the file you just created.
+6. SSH into the server and see if your key works
+
+#### On Linux/OS X
+
+1. Open a terminal and run `ssh-keygen` then follow the prompts.
+2. Copy the contents of your `id_<algorithm>.pub` file (example: if your key was generated with rsa, it will be named `id_rsa.pub`). This file is usually located in `/home/YOURUSERNAME/.ssh/`
+3. Paste the contents of the .pub file into a new file inside the `plugins/SSHD/authorized_users` folder and name the file just the username that the user will use to login with (example: `justasic`, there should ***NOT*** be a file extension or authentication does not work).
+
+## Using existing keys
+
+#### On Windows
+
+1. Ensure [Putty](https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html) is installed and open up `puttygen` (you can search for it in start search).
+2. Click `Conversions` then click `Import Key` and select your .ppk file.
+3. Copy the text from the big `Public key for pasting into OpenSSH authorized_keys file`
+4. Create a new file inside of the `plugins/SSHD/authorized_users` folder and name the file just the username (example: `justasic`, there should ***NOT*** be a file extension or authentication does not work).
+5. Paste the key you copied from step 3 into the file you just created.
+6. SSH into the server and see if your key works
+
+#### On Linux/OS X
+
+1. Copy the contents of your `id_<algorithm>.pub` file (example: if your key was generated with rsa, it will be named `id_rsa.pub`). This file is usually located in `/home/YOURUSERNAME/.ssh/`
+2. Paste the contents of the .pub file into a new file inside the `plugins/SSHD/authorized_users` folder and name the file just the username that the user will use to login with (example: `justasic`, there should ***NOT*** be a file extension or authentication does not work).
+
+Plugin Usage
+============
+
+## Commands
+
+    /mkpasswd <hash|help> <password>
+
+mkpasswd supports the following hash algorithms:
+
+- bcrypt - Using the OpenBSD-style Blowfish password hash
+- sha256 - Using a basic salted sha256 hash
+- pbkdf2 - Using the [PBKDF2](https://en.wikipedia.org/wiki/Pbkdf2) password hash
+- PLAIN - Using plain text passwords (very insecure)
+
+## Permissions
+
+`sshd.mkpasswd` - Checks if the in-game user has access to run the mkpasswd command.
+
+SSHD uses cryptographic certificates or a secure username and password to verify remote access.

+/**
+ * BCrypt implements OpenBSD-style Blowfish password hashing using
+ * the scheme described in "A Future-Adaptable Password Scheme" by
+ * Niels Provos and David Mazieres.
+ * <p>
+ * This password hashing system tries to thwart off-line password
+ * cracking using a computationally-intensive hashing algorithm,
+ * based on Bruce Schneier's Blowfish cipher. The work factor of
+ * the algorithm is parameterised, so it can be increased as
+ * computers get faster.
+ * <p>
+ * Usage is really simple. To hash a password for the first time,
+ * call the hashpw method with a random salt, like this:
+ * <p>
+ * <code>
+ * String pw_hash = BCrypt.hashpw(plain_password, BCrypt.gensalt()); <br />
+ * </code>
+ * <p>
+ * To check whether a plaintext password matches one that has been
+ * hashed previously, use the checkpw method:
+ * <p>
+ * <code>
+ * if (BCrypt.checkpw(candidate_password, stored_hash))<br />
+ * &nbsp;&nbsp;&nbsp;&nbsp;System.out.println("It matches");<br />
+ * else<br />
+ * &nbsp;&nbsp;&nbsp;&nbsp;System.out.println("It does not match");<br />
+ * </code>
+ * <p>
+ * The gensalt() method takes an optional parameter (log_rounds)
+ * that determines the computational complexity of the hashing:
+ * <p>
+ * <code>
+ * String strong_salt = BCrypt.gensalt(10)<br />
+ * String stronger_salt = BCrypt.gensalt(12)<br />
+ * </code>
+ * <p>
+ * The amount of work increases exponentially (2**log_rounds), so 
+ * each increment is twice as much work. The default log_rounds is
+ * 10, and the valid range is 4 to 31.
+ *

Author	SHA1	Message	Date
Justin Crawford	0afba39d57	This should actually fix rmichela#10	2019-10-06 02:58:52 -07:00
Justin Crawford	1b4c7c2304	Update readme as it's wildly out of date	2019-10-06 01:07:39 -07:00
Justin Crawford	4a39525809	Added 3 new password hashing schemes Support for bcrypt, sha256, pbkdf2 and plain text ofc. This makes password-based auth actually secure.	2019-10-06 00:11:13 -07:00
Justin Crawford	73c30f5214	You can now configure the MOTD, also fixed an old bug. You can customize the MOTD you see when you login (with the exception of what server you're logged into and some other info) and this includes colorization support via minecraft color codes (you need the special color code character that minecraft uses though, the example motd.txt has an included rainbow you can work from.) Hopefully fixed an old bug with the logger writting to the disconnected client session which causes a ton of exceptions because the session is gone.	2019-10-04 23:27:31 -07:00
Justin Crawford	3e45f7ebf4	Tweak the SSH MOTD a bit	2019-10-03 22:16:29 -07:00
Justin Crawford	0e05bb61bc	Support CTRL+D for exiting the console Support CTRL+D for exiting the console, also support "cls" for clearing the screen (on supported terminals).	2019-10-03 21:41:02 -07:00
Justin Crawford	0635ea7a35	Fixed a bug (open on the upstream fork), also rewote config. Fixed a bug that caused sessions to get overwritten and some of them would seem to freeze, the whole thing relied on undefined behavior. This bug was a static variable that copied sessions all around globally. Rewrote the config to support a few more options (the PasswordType is coming soon) and explained how the new authorized_users files work. Public key authentication now has the same number of retires that password authentication has (this aligns with how OpenSSH does it) and the number of retries can now be configured in the configuration.	2019-10-03 21:07:00 -07:00
Justin Crawford	25287b1580	Fix Travis	2019-10-02 19:41:31 -07:00
Justin Crawford	0458179597	Add support for authorized_keys files. Each user can have a set of authorized keys for public key authentication. This is better to support as it lets us use different algorithms and not just RSA. In the age of security, it's good to have variety. I also added additional libraries to support ed25519-based public keys. I updated the SSH libraries so any upstream bug fixes are applied, fixed some warnings and a few other things.	2019-10-02 19:14:56 -07:00
