This file describes the webserver CryptoNAS.
The CryptoNAS enables you to control the plaintext or encrypted harddisks of
your server via a webinterface.
Read on if you want to install the cryptobox-server package on your computer.

For more information, see the website:
	http://cryptonas.org

--------------------------------------------

1) Requirements
	- Linux 2.6
	- super (to selectively gain root privileges)
	- Python 2.4
	- some python packages:
		clearsilver 0.10 for python
		python-configobj 4.x
		cherrypy 2.x


2) Installation
For Debian, Ubuntu and other derivates you should use the debian package:
	see http://systemausfall.org/toolforge/debian/

Please follow the /usr/share/doc/cryptobox-server/README.Debian for
any special steps regarding Debian.

There are currently no official rpm or other packages of the CryptoBox.
Use the source installation on non-deb based distributions.

For source installation follow these steps:
	Get the source:
		http://cryptobox.org/download

	Extract tarball and change to the new directory:
		tar xzf cryptobox-0.?.?.tar.gz

	Install the program:
		python setup.by install

	Fulfil the requirements:
		read more in the user documentation

The installed python modules can be found in your local python installation directory.
The default location should be:
	/usr/lib/python2.4/site-packages/cryptobox/
The data files are (by default) installed to:
	/usr/share/cryptobox-server/

As some actions of the cryptobox require root privileges, you have to add the
following line to /etc/super.tab:
	CryptoBoxRootActions	/usr/bin/CryptoBoxRootActions	cryptobox
The script /usr/bin/CryptoBoxRootActions is used to execute all actions
requiring root privileges. Please check it to make sure, that your system will
not get compromised.


3) Setup

 a) Start at bootup
	Set NO_START in /etc/default/cryptobox-server to "0".
	The CryptoBox webserver will get started by its runlevel control script
	after bootup.

 b) Define managed devices
	You may restrict which blockdevices should be accessible to the CryptoNAS.
	Simply set [Main]->AllowedDevices in /etc/cryptobox-server/cryptobox.conf
	to a comma separated list of device prefixes: e.g. /dev/sd gives access to
	all SCSI devices, while /dev/hda3 restricts it to this single partition.
	The user executing the webserver (by default: 'cryptobox') must have write
	access to these devices. Usually the cryptobox user is member of the 'disk'
	group. This gives control over most devices.
	Be careful with this setting, as you may expose important data to public
	read and write access.

 c) Listening port and interface
	By default, the CryptoBox webserver listens to tcp port 8080 on all network
	interfaces. You can change this setting in /etc/default/cryptobox-server.
	Also take a look at your firewall settings.

 d) Disable plugins
	The CryptoBox contains a lot of plugins. As some of them could expose
	unwanted features to your users, you should carefully select which plugins
	to disable.
	Quite likely candidates for disabling are:
		- shutdown: poweroff or reboot the computer
		- network: change IP, gateway or dns settings of the server
		- partition: partition blockdevices
		- volume_format_fs: format a disk/partition (plaintext/encrypted)
	Take a look at /usr/share/cryptobox-server/plugins for the list of
	other plugins.
	The setting [Main]->DisabledPlugins in /etc/cryptobox-server/cryptobox.conf
	is a comma separated list of plugin names. Capitalization is important!

 e) Separate configuration partition
	The CryptoBox webserver requires a writeable directory for proper
	operation. If your root filesystem is not writeable (e.g. booting from a
	cdrom, read-only mounted flash memory, ...) you may use a seperated
	partition to store runtime settings. The CryptoBox will automatically
	creates it, when you use partition one of your disks with its interface.
	The setting [Main]->UseConfigPartition (see
	/etc/cryptobox-server/cryptobox.conf) defines, whether you want to use a
	separate partition (value "1") or if you want to store your runtime
	settings in the root filesystem (typically below
	/var/cache/cryptobox-server).

 f) Samba/WebDAV/NFS/??? integration (aka. event script handling)
	The CryptoBox allows you to add event handling scripts for most of the
	interesting events: bootup/shutdown of the webserver and mount/umount
	of single volumes.
	If you want to automatically publish your mounted volumes with samba
	or similar fileservers, then you should take a closer look at the
	example scripts for samba and apache-webdav in
	/usr/share/doc/cryptobox-server/event-scripts.
	You may also just publish the mount directory of the CryptoBox. This
	will expose all mounted volumes very easily. Review the configuration
	file for the setting [Locations]->MountParentDir.

 g) Take a close look at the configuration file to check all other options
	before you start the CryptoBox webserver.


4) Usage
Use your favourite web browser to go to http://localhost:8080 and browse the
webinterface of the CryptoBox.
Some parts of the interface are restricted to administrative access. The
default access combination is the user 'admin' and the password 'admin'. Please
change this setting immediately.
The plugin 'user_manager' allows you to add users and to change passwords.
The plugin 'plugin_manager' lets you configure, which plugins require
administrative authentication.


5) Data access
Before you can access your plaintext or encrypted data on a volume, you have to
open it. To accomplish this, you have to go to the webinterface, select the
appropriate volume and click on "Open volume" in the "Activation" tab.

If you are running the CryptoBox locally, then you can access all open volumes
below the 'MountDir' as specified in the configuration file
(/etc/cryptobox-server/cryptobox.conf). The default mount location is
/var/cache/cryptobox/mnt.

If the CryptoBox package is running on a networking server, then you have to
configure your favourite fileserver (e.g. samba, webdav, nfs, ftp, ...) to
publish the subdirectories of the 'MountDir' (see above).
If you want to customize the publishing of volumes, then you may use the
event script feature fo the CryptoBox. See event-scripts/README for details.
