Download SD-Card content - my workaround solution
« on: February 23, 2014, 02:42:08 AM »

This has been bugging me for sometime. Only yesterday I found out about the telnet access and tried to figure out how to start a FTP service from it but no joy, as the busybox doesn't have the inetd module for a simple FTP access.
So I started meddling with its HTTP server (lighttpd) and noticed everytime I change its configuration, the service init script actually rewrites the conf. file  :-\
My workaround was, to start another lighttpd server on a different port which will show the content of the SD card
and download specified directory using wget.

My camera address is 10.0.0.20

1. enable telnet server
http://10.0.0.20/cgi/admin/telnetd.cgi?command=on

2. login to cam's busybox
telnet 10.0.0.20
user: root
password: admin

3. create a new lighttpd configuration file to run on a different port (i chose port 3000)
vi /etc/lighttpd/light.conf
(press i for text insertion)
server.document-root = "/mnt/usb/dcs-942l/"
server.port = 3000
dir-listing.activate = "enable"
press esc
type :wq and enter to write the file and exit

notice - "/mnt/usb/dcs-942l" i believe is the default sd directory which is created when formatting the sd card the standard way. make sure it's the same name on your camera by typing
ls /mnt/usb

4. start the extra lighttpd daemon:
lighttpd -f /etc/lighttpd/light.conf -m /lib
you should get a message that the server started successfully.

5. exit telnet (by exit command) and browse to your newly created web server at
http://10.0.0.20:3000
you should see a list of all the directories on the SD card.

6. download a directory
i'm running Linux so I used wget, I'm sure there are other options for Windows
or you could use wget for windows http://downloads.sourceforge.net/gnuwin32/wget-1.11.4-1-setup.exe

wget -r -l2 --no-parent -A.avi http://10.0.0.20:3000/20140222/
r stands for recursive,
l stands for directory level,
-A.avi will download only AVI files
and the http address is an example of a certain date i downloaded,
you can get the exact http address required, from your web browser by right clicking on a directory  and copy link address.

There you have it. Wget will download all video files from the directory .

don't forget to close the telnet access
http://10.0.0.20/cgi/admin/telnetd.cgi?command=off

restarting the camera will close the extra lighttpd server, i don't think it's a good idea to add it to its startup script.

Thanks for the steps. I like this. But is there a way to password-protect "http://10.0.0.20:3000/"?

yes, I improved the light.conf  file since . here's the new one:

Code: [Select]
server.modules += ( "mod_auth" )
server.document-root = "/mnt/usb/dcs-942l/"
server.port = 3001
ssl.engine = "enable"
ssl.pemfile                = "/tmp/server.pem"                       
ssl.cipher-list                    = "RC4-MD5 RC4-SHA AES128-SHA AES256-SHA DHE-RSA-AES128-SHA DHE-RSA-AES256-SHA"
auth.backend                            = "htdigest"                           
auth.backend.htdigest.userfile = "/tmp/lighttpd-htdigest.user"   
auth.require = (
        "/" =>
        (
                "method" => "basic",
                "realm" => "DCS-942L",
                "require" => "user=admin"
        )
)
dir-listing.activate = "enable"

it will only accept the admin password.
the server now listens on https port 3001
to start the sever use

lighttpd_ssl -f /mnt/usb/dcs-942l/light.conf -m /lib

i noticed that after every camera restart the file would get erased so now i'm storing it on the sd card .

also, my wget command now is

wget -r -l2 --no-parent -A.avi --http-user=admin --http-password=password --no-check-certificate https://10.0.0.20:3001/20140227

1. enable telnet server
http://10.0.0.20/cgi/admin/telnetd.cgi?command=on

Telnet access has been removed in V2.11.04 23 :-(

Glad you got it working. Seems the telnet was removed from V2.xx FW.
