Axel download manager for dreambox (dm800)

Filed under: DreamBox — Tags: , , , , — admin @ 4:57 pm

From Axel Project official site :

Axel tries to accelerate HTTP/FTP downloading process by using multiple connections for one file. It can use multiple mirrors for a download. Axel has no dependencies and is lightweight, so it might be useful as a wget clone on byte-critical systems.

I found a working compiled version of axel download manager for my dm800.
You can download it from here : Click here to download axel mipsel
First decompress the zip file then put it in /usr/bin folder of your dreambox and make it executable and enjoy 🙂

How to install nano on your dreambox

Filed under: DreamBox — Tags: , , , — admin @ 2:50 am

The bundled vi package with dreambox really sucks ! and I am a big fan of nano text editor , as always I was disappointed to find a rebuilt nano package in Gemini or even dreamboxupdate repos , so I searched the net and wonderfully found a nano package which works with my dm800 😀
instruction to install nano :

cd /sbin
mv mipsel-nano_2.0 nano
chmod +x nano

Set date,time and timezone on dreambox (dm800)

Filed under: DreamBox — Tags: , , , , — admin @ 6:49 pm

You can set the time and date on dm800 by following command :

date -s YYYY.MM.DD-hh:mm:ss

YYYY is Year
MM is Month
DD is Day
hh is Hour (0-24)
mm is Minute
ss is Second

for changing the timezone , first get a file list of cities by following command :

ls /usr/share/zoneinfo/

choose your city or nearest city to you , then use the following command to change the timezone ( replace YOUR_CITY with your chosen city ) :

ln -sf /usr/share/zoneinfo/YOUR_CITY /etc/localtime

How to setup a PPPOE connection on your dreambox

Filed under: DreamBox — Tags: , , , — admin @ 3:58 pm

Setting up a PPPOE connection on my dm800 was one of the hardest challenges I’ve ever had , I wonder why there is no documentation about it on the net ! I guess I am the first one documenting it in the world 🙂
In this article we will install PPPOE on my dm800 box , I have Gemini 4.6 installed on it now. a “uname -a” command give the following output :

root@dm800:/etc# uname -a
Linux dm800 2.6.12-5.1-brcmstb-dm800 #1 Wed Mar 11 20:59:15 CET 2009 7401c0-nand unknown

first we need to install several kernel modules on our dreambox :

ipkg install kernel-module-slhc
ipkg install kernel-module-ppp-generic
ipkg install kernel-module-pppox
ipkg install kernel-module-pppoe

then we need to install PPP and PPPOE package , I don’t know why they are not available in default repo of Gemini image , but after a lot of search I found them in repo , so next step is to download and install them :

cd /tmp
ipkg install ppp_2.4.3-r2_mipsel.ipk
ipkg install ppp-oe_2.4.3-r2_mipsel.ipk

after installing all of required packages , we need to load the required kernel modules into memory.
so run the following commands :

depmod -a
modprobe pppoe

now we should have all required kernel modules loaded :

root@dm800:/etc/init.d# lsmod
Module                  Size  Used by    Tainted: P
pppoe 12416 0 - Live 0xc01ed000
pppox 2864 1 pppoe, Live 0xc01a8000
ppp_generic 29792 2 pppoe,pppox, Live 0xc01b3000
slhc 7552 1 ppp_generic, Live 0xc01a5000

Please note pppoe kernel module is loaded now.

OK , now we are ready to go and connect our PPPOE connection , to do this simply run the following command ( change USERNAME & PASSWORD in following command to your own PPPOE username and password ) :

pppd plugin eth0 user USERNAME password PASSWORD noauth defaultroute replacedefaultroute persist maxfail 0

thats it 🙂 if you have done everything correctly now , you should be connected now.
to disconnect from your PPPOE connection , simply run the following command :

killall pppd

Troubeshooting :
Sometimes I noticed , pppoe module doesnt get loaded (by command “modprobe pppoe”) with an error message while I had all required modules installed , after a lot of tries and errors I found out a reinstall of ppp_2.4.3-r2_mipsel.ipk resolves the issue , may be it is a bug.
After you have pppoe loaded in memory and checked it by “lsmod” command , if your connection still does not work , you can debug it by running syslog daemon and adding a “debug” option to the end of “pppd” command as follows :

pppd plugin eth0 user USERNAME password PASSWORD noauth defaultroute replacedefaultroute persist maxfail 0 debug

now you can go to “/var/log/” folder and check messages file. any errors or problems should be reported there , I suggest you to open another telnet or ssh to your dreambox and run the following commands :

cd /var/log/
tail -f messages

and now run the pppd , you can simultaneously see all debug messages.
