#securbox - SecurStick Linux Wrapper securbox is a wrapper program for SecurStick under Linux, written as a bash script. It's able to connect to your SecurStick via commandline, mount or unmount it and is able to set up the SecurStick Safe Zone.

Also have a look onto the other branches (dev and state-of-work) :)

#Requirements

• davfs2 (mount.davfs) for mounting SecurStick webDAV share
• awk for get the address from output file (awk should be installed by default)
• cURL to get pages and POST password.
• realpath for getting absolute paths of the SecurBox home directory
• SecurStick
• Zenity can be used for asking for password by a GUI. (optimal)

#Prerequisites

##Packages Install davfs, realpath and cURL packages:

sudo apt-get install davfs2 realpath curl

Optional also install zenity:

sudo apt-get install zenity

##SecurStick Go to SecurStick Homepage and download SecurStick.

##securbox Clone this repository into a favourite directory

• via SSH with git clone [email protected]:criztovyl/securbox.git or
• via HTTPS with git clone https://github.com/criztovyl/securbox.git

#"Setup"

• In these steps I use vim, if you don't want to use vim, replace it with nano.
• Choose a folder for your securbox (default is .securbox in the user's home directory)
• Extract SecurStick into it (if you only want to use it on Linux, take SecurStick-linux only)
• If you want to be able to start your securbox from every dir, include securbox into your PATH. (Add export PATH=$PATH:/path/to/securbox-dir to your .bashrc)
  TODO: Multiple securboxes.
• Now you should add the securbox to fstab so that you can mount it as a normal user.
  • We're doing this by adding securbox to fstab, setting up the davfs2 secrets file, fixing a mount.davfs bug and adding the user to the davfs2 group.
  • Add http://127.0.0.1:2000/X /media/securbox davfs user,noauto 0 0 to your /etc/fstab file (sudo vim /etc/fstab)
    (you can use a different mounting point but then you have to change it also in the securbox file, same way as setting the home in the point below, but look into line 24 instead of 21 ;) )
  • the SecurStick DAV is not secured with user and password so you can simply add no user and password to the DAV secrets file (vim ~/.davfs2/secrets): /media/securbox "" ""
  • There is a bug in mount.davfs when not mounting as a root user, telling you program is not setuid root. Fix this using sudo chmod u+s /sbin/mount.davfs
  • Add your user to davfs2 group: sudo adduser $USER davfs2
• Open the securbox file and change the securbox home to the folder you've chosen in the first point (line 21; use $HOME instead of ~ to identify your home directory)
• Now you can use securbox :)

#Usage To start securbox, type

 securbox start

into your command line. If you havn't set up your securbox, this will be done immediately as shown below.

Meanwhile securbox will start but the script needs to wait some seconds (3) to let SecurStick start up. So the following output is normal:

Waiting for SecurStick startup...
3 seconds remaining...
2 seconds remaining...
1 seconds remaining...
Continue...

This will not happen every time because SecurStick maybe already running, as example if you entered the wrong password. Now set a password if you didn't yet:

Please set a new password for your securbox with at least 5 letters, both UPPER and lower case, at least one digit and at least one special character (like !,?,#).
Enter password  : 
Repeat password : 

If your passwords match and are strong enough, securbox will set up the Safe Zone and log in:

Please set a new password for your securbox with at least 5 letters, both UPPER and lower case, at least one digit and at least one special character (like !,?,#).
Enter password  : 
Repeat password : 
Logged in :)
Mounted.

Sometimes you will get the below messages. If you get them something went wrong. Kill securbox with securbox kill and then restart with securbox start.

/sbin/mount.davfs: connection timed out two times;
trying one last time
/sbin/mount.davfs: server temporarily unreachable;
mounting anyway

Now you can use your securbox. Go! Go to work!
If you're finisched, you can close the securbox by typing

securbox stop

This will unmount your securbox and stop it. Maybe you will see mount waiting for synchronsation of the cache. Simply wait.

/sbin/umount.davfs: waiting while mount.davfs (pid 13987) synchronizes the cache .. OK

#Troubleshooting

If your files in the webDAV folder are not accessable, stop and kill securbox (with securbox stop and securbox kill) and try again.

#Meta

##Background I'm using SecurStick to carry my "top secrect" stuff with me in my Dropbox.

The early time, I simply started the SecurStick with a ugly double-click (as if we wold be in Windows...) and then SecurStick mounts to Nautilus.

After a while I wanted to access the data from SecurStick via command line. But mounted in Nautilus that doesn't work.

Then I've searched for a possibility to mount the (web)DAV share and found davfs2. But it's very uncomfortable when you do this manually: First you have to open the FileManager, go to the SecurStick folder, double-click SecurStick, waiting the web browser to start, enter password, unmount from nautilus (neither it's unnecessery), open command line and mount.

So I've written this script.

###Problems I've found no documentation about SecurStick command line usage so I search the hard-coded strings in the executable, as example how to disable nautilus mount and disable opening the browser. (Described at the end of the file)

After that I found out, that you can't simply POST password and unlock SecurStick, you have to GET the index and the image first.

###ToDo

• PATH independency (?)
• multiple securboxes
• make useable off commandline (Zenity)
