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 wget http://downloads.nas-central.org/LS2_MIPSel/Packages/mipsel-nano_2.0 mv mipsel-nano_2.0 nano chmod +x nano
I am creating this post mostly for my own reference in future , the scenario is that my ISP gives me a free PPPOE username and password with unlimited traffic to download between 3am-7am and I didn’t want to keep my desktop PC up and running on midnights , so I thought I can make my dreambox which is always on an automatic midnight super downloader and after 24 hours of work , I accomplished it.
1.Create a file named “dl” containing the commands to download files in /media/sda (where flash disk is mounted) , format of file is :
wget -q -c "ftp://user:pass@ftphost/filename1" & wget -q -c "ftp://user:pass@ftphost/filename2" & ....
2.make it executable :
chmod +x /media/sda/dl
3.edit /etc/ppp/ip-up and add the following to the end of file :
cd /media/sda /media/sda/dl echo "`date` : PPPD IP-UP" >> /media/sda/dl.log
4.edit /etc/ppp/ip-down and add the following to the end of file :
killall wget echo "`date` : PPPD IP-DOWN" >> /media/sda/dl.log
ip-up is automatically called when PPP connection is established. it starts all downloads automatically.
ip-down is automatically called when PPP connection is disconnected. it stops all downloads automatically.
5.Create monitor-pppd in /media/sda and put the following inside it ( also make it executable ) :
if [ ! -e "/proc/sys/net/ipv4/conf/ppp0" ];
then
echo "`date` : restarting pppd" >> /media/sda/dl.log
killall pppd
pppd plugin rp-pppoe.so eth0 user USERNAME password PASSWORD noauth defaultroute replacedefaultroute
fi
6.create a cron job by creating a file named root inside /etc/cron/crontabs folder and paste the following inside it :
* 3,4,5,6 * * * /media/sda/monitor-pppd
and restart the cron daemon by calling :
/usr/script/crond_script.sh restart
the cron daemon will establish the PPPOE connection automatically and monitor-ppd will monitor it.
don’t forget the time should be synchronized and timezone should be set correctly.
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
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 dreamboxupdate.com repo , so next step is to download and install them :
cd /tmp wget http://dreamboxupdate.com/opendreambox/1.5/dm800/feed-rel_27/ppp_2.4.3-r2_mipsel.ipk wget http://dreamboxupdate.com/opendreambox/1.5/dm800/feed-rel_27/ppp-oe_2.4.3-r2_mipsel.ipk 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 rp-pppoe.so 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 :
syslogd pppd plugin rp-pppoe.so 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.
Open livezilla/_config/config.inc.php file.
Search for $CONFIG[“gl_c_param”] in the file and comment or remove the line.
All Done 🙂
