## Repositories

    If you want to have an access to non-free, contrib and multimedia repositories just change
    "sources.list" file adding new server addresses.
    There are two ways to do so:
       1. Midnight Commander's built-in text editor: Menu-> Accessories-> Terminal:
          a. Tab "Options" -> Configuration-> use internal edit-> make sure it is marked and Save it.
          b. Go to: /etc/apt/sources.list.d/debian.list -> edit it with F4 key.
          c. Change a line:
          d. For new one you can see below:
          e. Add new line of multimedia repo:
          f. Save the file with F2 bottom and escape using F10 key.
          g. Enter file: /etc/apt/sources.list.d/sidux.list and change the line for:
          or:
          h. Save it and quit Midnight Commander.
    2. Mousepad text editor -> Terminal
       (sux command lets run softwares in graphic environment straight from a text console as root)
       a. Change first line and add other repositories addresses as you did using "mc".
       b. Tab File-> Save it and close editor.
    3. Download "debian-multimedia-keyring" package (public key) from: http://debian-multimedia.org/
    Go to Terminal and (as a root) install it:
       b. Refresh packages list:
       c. And install updates:

## Language packages

    If you have chosen different language than English you may install missing language packages.
    Just check what's available to get, I used to install additional polish packages:
    For KDE I install package:

## Firewall

    The firewall "iptables" is pre-installed with the system, what you have to do is activate it.
    1. The simplies way to do that is use "ufw" (Uncomplicated Firewall) so create two rules for firewall:
       all outgoing connection are allowed and all incoming connections are blocked:
    You should get confirmation:
    You can always check the firewall status:
    Or deactive it (I suggest not):
    2. There is an another way to activate firewall using GUI software like Firestarter or Gufw
       or Guarddog for KDE.

## Mounting partitions

    After system installations all partitions should be detected and mounted automatically
       in "/media" folder.
    In a case if anyone missing you can mount it manually.
    Run terminal and type:
    You will get a list of all partitions on your computer drive including not mounted.

#### Pernament mounting

    All partitions will be mounted pernamently editing "fstab" file, type it in Termial as root:
    1. "ntfs" file system partition (for example /dev/sda1) read only: add the line on the end of the list:
       a. Do not use "Space" button but "Tab" only.
       b. Create "sda1" subfolder in "/media":
       c. And install "ntfs" package if needed:
    2. "fat32/vfat" file system partition (for example /dev/sda5), read and write - add the line:
       or
       Create "sda5' subfolder in "/media":
    3. "ext3" or "ext4" (for example /dev/sda6) - add the line:
       Create "sda6" subfolder in "/media:
    4. "swap" partition (for example /dev/sda7) - add the line:
    Any "fstab" file changes will be working after system rebooting.

#### Temporary mounting

    Partitions can be temporary mounted for a session time.
    1. Create "new" subfolder (for example) in "/home" directory and mount a "vfat" (sda5) partition:
    2. The mounted partition will be unmounted automatically after system reboot or having command:
