====== Userbox ======

The former User-VM has been replaced by a docker container called the userbox.
It can be accessed by SSH, SFTP and X2Go for a graphical Desktop

===== SSH Access =====

==== SSH Access from Windows ====
# Download the [http://the.earth.li/~sgtatham/putty/latest/x86/putty.exe latest putty executable] and start it
# Enter "user.zom.bi" as Hostname and "2233" as Port
# Click "Open" on the bottom of the Form in order to connect
# You will get an error message showing an unknown Host key on the first connection. Confirm this Dialog Window with "Yes"

==== SSH Access from Linux ====

You should be able to access the ssh server on the userbox using the following command:
ssh user@user.zom.bi -p 2233

You can also mount your home directory from the userbox to your local filesystem in order to work on your webpages etc.
mkdir uservm-mount
sshfs user@user.zom.bi:/home/user uservm-mount -p 2233

=== Authentication using ssh keys ===

If you do not like to enter your password every time you can create an ssh key and use this in order to login to the userbox and your webspace

ssh-keygen
ssh-copy-id user@user.zom.bi -p 2233

==== Files and file permissions ====

The ''Public'' folder inside your home directory (''~/Public'', or ''/home/[user]/Public'' alternatively) contains the files you are sharing on your public Userpage.

Please note that the files you put there will be able to be read by anyone without authentication.

To reflect this, you need to make a couple changes:
# The ''Public/'' directory needs to be created, as it does not exist by default
# Shared folders must have the "Global readable+executable" permissions.
# The files permission must be set to "Global readable"

To automatically share all files and folders inside your public dir, you can use the following code snippet:

<syntaxhighlight lang="bash">

# Assign all directories in ~/Public the permission mask 0755
find ~/Public -type d -exec chmod 755 {} \;

# Assign all files in ~/Public the permission mask 0644
find ~/Public -type d -exec chmod 644 {} \;

</syntaxhighlight>

===== Graphical Access via X2Go =====

# Download X2Go Client for Windows from the [http://wiki.x2go.org/doku.php X2Go Website]
#* if you are using the Linux the package will most probably be called "x2goclient" and is installable from the repositories for ubuntu, debian and opensuse
# Start the Client and Create a new connection profile [[File:X2go 01 new session.png|thumb|right|New Session]]
# Enter the connection Information.
#* Make sure to select "XFCE" as desktop environment as the default selection ("KDE") is not installed on the userbox and will only lead to an error message
#* enter your username in the "Login" field
#* Confirm the Settings with "OK" - the new session should be created and should show up in the right side of the window[[File:X2go 02 session parameters.png|frame|center|Session Parameters (click to enlarge)]]
# Select the newly created session
# Enter your LDAP password in the password field
# After a few seconds you should see the desktop of the user box. By default the session starts with a resolution of 800x600 but you can resize this window however you like
#* if you close this window the session will be disconnected but all programs running will still execute and you can resume after reconnection
#* if you are done and do not need any programs running on your desktop please logout with the "emergency exit" icon in the top bar.
