How-to install and configure Newcamd 5.05 on a
1.07.4 original firmware from scratch

__________________________________________________ ______________________________

WARNING: this document describes the step-by-step procedure for installing and properly configuring Newcamd Cardserver 5.05 executables on an original 107_4 firmware by Dream Multimedia, for using it with official smart cards for pay-tv channels.
There aren’t described illegal procedures for viewing channels without a regular smart card inserted into dreambox’s smart card readers.

Hello to all

Some people asked to me to write a little explanation about installing the new emu Newcamd on a straight and clean 107.4 original DMM image, so I decided to put this doc online, thinking that, probably, some other people may be interested in it too.
This doc is intended to be as an (hoping) easy help, also to whom who are almost newbies with Dreambox and Linux scripts and programming.

First of all, here’s all the needed tools:

- Crimson Editor, a well made Linux-Unix editor usable from Windows, you can download it from its homepage, it is freeware: http://www.crimsoneditor.com/

- A FTP program for Windows,, LeapFTP is the best for me.
You can find it on http://www.leapware.com/

- The necessary tools for unpacking and repacking cramfs images on the dreambox, uncramfs, mkcramfs and mksquashfs, included the two scripts that make easy the call to these executables from command line: undreamboxfs and mkdreamboxfs (this last one was modified by me and included as “mkdb”, I will explain later why this script needed to be modified).

- The original archive of the emulator Newcamd Cardserver 5.05: “newcamd-v5.05.zip”

- The original firmware 1.07.4 by DreamMultimedia, rel107_4.img

- A hard disk or an Usb Stick mounted into dreambox (hard disk is faster and better to use).

IMPORTANT-Where to find all necessay files?:

To make easy the search for files, I inserted the original Newcamd 5.05 archive, plus all the needed scripts and commands, plus the necessary lib for the new image, plus this document in Adobe Acrobat format, in other words all necessary files (only excluded LeapFTP, Crimson Editor, and rel107_4.img) are presento into the attached archive
HOW-TO INSTALL NEWCAMD FROM SCRATCH (DOC).zip
You'll find it at the end of this online doc.

Let’s begin our work, first by creating an image development environment into dreambox:

- Open a Telnet session from Windows:
Click on “start” button and select “Execute”
Into the text box write telnet <ip.of.my.dream> (in example: “telnet 192.168.0.24”)
When the command prompt window opens, input username and password, normally the default root and dreambox.
- Once logged in, type cd hdd [enter] if you have the hard disk mounted into your dreambox, or cd /mnt/usb [enter] if you have only the usb stick (note: using hard disk is far better).
From now, I will no more write the text [enter], the “enter” key on the keyboard has as ever to be pressed after evrery command line written in bold characters.
- Create a temporary directory for working: mkdir temp , and enter into it with cd temp
- Copy with your FTP program all the necessary tools into this temp directory (you will find all these tools, listed above, into the “cramfs tools” directory presento into this how-to…doc archive):
uncramfs, mksquashfs, mkcramfs, undreamboxfs, mkdb
After the transfer, go to Telnet window and give the permission to run to all of these copied files, you can enter a single command line for all: chmod 755 *
All files are now executables.
- Then do the transfer of the original rel107_4.img image on which we will work into this same temp directory. As ever, use your FTP program to do it..

Unpacking the original image into a folder:

- From Telnet window, type the command line ./undreamboxfs rel107_4.img newimg
This statement, will execute the tool uncramfs called by the script undreamboxfs, and it will uncramfs (expand) the original image into a directory called “newimg”, by creating it into our temp working folder.
- Go back to FTP program, give a refresh of the window, and enter into the new unpacked image’s directory “newimg”

Preparing original image for installing Newcamd:

- The folder that we will use for modifying the image is the var_init folder.
- From Telnet, enter into this directory with: cd newimg/var_init
You’ll see that some directories are already present into var_init, but we need to create some more, then let’s go on….
- Now create the missing directories that we will use for Newcamd installing:
mkdir bin
mkdir lib
mkdir keys
mkdir scce
- Go to the FTP program, enter into lib directory (the one present into var_init), and copy into it the file libcrypto.so.0 , a library functions file that is needed by Newcamd to run (and needed also by many other dreambox emus).
You will find this library into the “lib” directory of this downloaded how-to….doc archive.
- Now unzip the included original “newcamd-v5.05.zip” archive into a folder on your Windows desktop.

- Let’s now begin to copy all the needed Newcamd executable files, from the unpacked Windows folder to the dreambox.

> Important: remember that the working directory into dreambox is the “var_init” directory. Be sure to have it selected and open in the transfer window of your FTP program.

- Copy the following files from the Newcamd archive main directory to the dreambox, into the folder scce:
The files to be copied are: ecmoverride, keylist, mappings, ppua, priority, rsakeylist, tpscrypt
Copy also all the files present into “nagrafiles” directory of Newcamd archive again into the folder scce on dreambox.

- Let’s talk now of bin folder: into this folder we will insert all the emulator’s executables.. As you can notice by looking into Newcamd archive, this emulator has been made for running on various systems and different CPUs, so the first thing to do is to find out which files are to be used, then rename them and then copy them into dreambox.
The right files to use with dreambox are the PowerPC executables, as the dreambox is provided with this CPU.
Let’s begin to rename and copy:
1) rename the file newcamd.ppc to newcamd (remove the extension .ppc), and then copy it into bin folder on dreambox.
2) from directory “camdcmd”: rename camdcmd.ppc to camdcmd and copy it into bin
3) from directory “cardserver”: rename betad.dream to betad; then rename cardserver.dream to cardserver; and then rename dcd.dream to dcd, and finally copy all of them into bin
4) from directory “cardspider”: rename cardspider.ppc to cardspider and copy it into bin
5) from directory “radegast”: rename radegast.ppc to radegast and copy it into bin
At last, from Telnet, go into the directory bin (cd bin) and type the command chmod 755 * for giving permission to run to all these files just copied.

Configuring the files newcamd.conf and cardserv.cfg

- Now we have to configure the emulator’s configuration files, that after will be copied into the tuxbox/config directory (always inside into thevar_init folder).
But first we have to write and/or change some lines into them, using Crimson Editor.

Let’s begin with newcamd.conf that you’ll find into the main archive directory of Newcamd.
Modify the following entries in the file (the other unlisted entries must be leaved unchanged).
Change their default values to the values shown below:

Code:

DEMUX_API = 2
BOX_TYPE = DM7000
CONTROL_WORD_DEVICE = CA
PMT_UPDATE_WATCH = no
DISABLE_CAM = yes
OSD = none

This last entry (OSD), should be set to “none” if you don’t want to see the popup message every time you change channel.
The other values must be set as listed above for the use of Newcamd on Dreambox DM7000.

Instead, the next two lines are to be ADDED later in the conf file, near to the end of the file, in the section where you will read “Cardserver list” (these are the parameters needed by newcamd for connecting to the card reader’s server, for properly reading smart card’s data):

Code:

CWS = dreambox 10000 root dreambox 01 02 03 04 05 06 07 08 09 10 11 12 13 14 net cardserver
CWS = dreambox 10001 root dreambox 01 02 03 04 05 06 07 08 09 10 11 12 13 14 net cardserver

At this point, you are done with newcamd.conf, save it and copy it into the folder tuxbox/config (always remember: we are always working into the same parent directory var_init).

Now configure the cardserv.cfg (find it into “cardserver” folder of the Newcamd archive), do the following modifies:

Leave unchanged all the top part of the file, go to the bottom of it until you see these three text lines:

Code:

#
# Example
#

Now DELETE all the rest of the file, from these lines to the end.
Then add the following lines to the end of the file, by copying and pasting from here, already edited by me.
By doing this, we will set in cardserv.cfg the same connecting parameters we already input on newcamd.conf.
These parameters allow the emulator to connect to the cardserver, to share the data read from the card and necessary for descrambling the watched channel.
As you can read, both of the card readers are enabled on dreambox, and all EMM are unblocked, as the relative entries EMM-* are all set to “yes”.
You can do a copy&paste from here to the file cardserv.cfg , putting these lines were was the delete ones.

Code:

DESKEY = 01 02 03 04 05 06 07 08 09 10 11 12 13 14
SERVER_NAME = cardserver
DEBUG_PORT = 14000
ADMIN_PORT = 14001
ENTITLEMENT_PORT = 14002
ADMIN_PASSWORD = secret 00 00 00 00 00 00 00 00 00 00 00 00 00 00
USER = root dreambox net dreambox 12000
#
# upper card slot
#
SERIAL_PORT = 0
TCP_PORT = 10000
EMM-G = yes
EMM-S = yes
EMM-U = yes
SPECIAL_FEATURES = yes
#
# lower card slot
#
SERIAL_PORT = 1
TCP_PORT = 10001
EMM-G = yes
EMM-S = yes
EMM-U = yes
SPECIAL_FEATURES = yes

Done! Save now this file and FTP it to dreambox into the same folder of the other config file:
tuxbox/config.

Let’s now modify the startup file of the firmware for starting the new emu at boot

Now we have all files inserted and configured, so we must tell to the image to start Newcamd 5.05 automatically at boot.
The file we need to modify is the famous rcS, this file is found into /etc/init.d/ folder, on image’s main directory (not in “var_init”, but in root).
Open it with Crimson, and go to the end of the file where you can see the loop that launches and checks Enigma.
The first list shown below is the original 107.4 loop, that runs the only emu actually present on an original image: the “dccamd” emu.
This emu is coded by DreamMultimedia, and allows to decode the well-known hardcore channel, owned by DMM itself, by using their original DreamCrypt smart cards.
____________________________

ORIGINAL LOOP

Code:

touch /tmp/.enigma
while [ -e /tmp/.enigma ]
do
    dccamd
    /bin/enigma
    ret=$?
    echo "enigma returned with "$ret
    case $ret in
        0)
            echo "Shutdown"
            rm /tmp/.enigma
            /sbin/halt
            ;;
        2)
            echo "Restart"
            ;;
	3)	    
	    echo "Reboot Flash"
	    killall -9 dccamd
	    rm /tmp/.enigma
	    umount /var
	    umount /hdd
	    sleep 2
	    /tmp/reboot
	    ;;
        *)
            echo "Reboot"
	    rm /tmp/.enigma
	    /sbin/reboot
            ;;
    esac
    killall -9 dccamd
done

exit 0

____________________________

Here’s instead the modified one, for starting Newcamd 5.05 automatically at boot.
As you can see, the “dccamd” emu disappeared, and now are present the calls first for “cardserver”, that initializes the dreambox’s smart card readers and opens the server for communication, and then the call to “newcamd” which is the real emu, that installs in memory as a client of cardserver.
Delete the old loop (all the above lines), and substitute them with the new loop listed below:

MODIFIED LOOP FOR NEWCAMD 5.05

Code:

touch /tmp/.enigma
while [ -e /tmp/.enigma ]
do
    rm -rf /var/tmp/camd.socket
    /var/bin/cardserver
    /var/bin/newcamd
    /bin/enigma
    ret=$?
    echo "enigma returned with "$ret
    case $ret in
        0)
            echo "Shutdown"
            killall -9 newcamd
            killall -9 cardserver
            rm /tmp/.enigma
            /sbin/halt
            ;;
        2)
            echo "Restart"
            ;;
	3)	    
	    echo "Reboot Flash"
	    killall -9 newcamd
	    killall -9 cardserver
   	    rm /tmp/.enigma
	    umount /var
	    umount /hdd
	    sleep 2
	    /tmp/reboot
	    ;;
        *)
            echo "Reboot"
	    killall -9 newcamd
	    killall -9 cardserver
	    rm /tmp/.enigma
	    /sbin/reboot
            ;;
    esac
    killall -9 newcamd
    killall -9 cardserver
done

exit 0

When done, save it as ever and copy it overwriting the old one in /etc/init.d/rcS
IMPORTANT: be sure that this file has permissions to run (755).
If not, the dreambox will hang at boot with black screen and empty display on its panel.

Last step: rebuild the final image!

Awesome! We are now ready to rebuild the cramfs image and install it in multiboot on usb stick or hard disk.

This is the last step for creating the cramfs archive with the image, as ever with the standard extension *.img

Go to Telnet window, and go back to thefirst created temp directory where we have the tools for rebuilding the image (mkcramfs, mksquashfs, mkdb).

It’s very easy, simply enter the command line:

./mkdb newimg 107_4+newcamd.img

This will rebuild the image with the name “107_4+newcamd.img” , of course you can change that name with your preferred one.
I said at the beginning of this document that a modify was needed for mkdreamboxfs script.
This because the standard script does not allow to generate an image that is bigger than standard cramfs partition, in other words you cannot build an image for multiboot install with the standard unmodified mkdreamboxfs script.
So I modified some lines into the script, and saved and included it into the tools directory with the name mkdb.
Use it as described above to generate this 107_4 plus Newcamd image.
At the end of the rebuild (this will take up to 2-3 minutes) you will find the new creaed image into the temp folder, copy it to your windows desktop, and……

YOU ARE DONE!
All to do is to open FlashWizard

and install your image in multiboot on usb stick or hard disk…..
Have fun!!
