mjpg-streamer web page authentication

Forum: Linux
puma 
Hi,

I've installed successfully my mjpg-streamer server and it's working fine
right now. However, I'm using the default web page and I want to have an
authentication for some protection in case i'll access it from public. How
can I apply the authentication? 

Thanks,
Puma

Hello,

You just have to add option to output_http module:

-o "output_http.so -w ./www -c UsErNaMe:SeCrEt"

Hi Vladimir,

I tried to add the option (see below command line), but didn't make it
through wherein the webpage still doesn't have an authentication. Please
advise.

[root@FriendlyARM mjpg-streamer]# ./start_uvc_yuv.sh -o "output_http.so -w
./www -c UsErNaMe:SeCrEt"

MJPG Streamer Version.: 2.0
 i: Using V4L2 device.: /dev/video0

Hello,

you are trying to specify parameters to shell script, instead you have to 
modify it in a text editor, or launch mjpg_streamer manually:

LD_LIBRARY_PATH="$(pwd)" ./mjpg_streamer -o "output_http.so -w ./www -c
UsErNaMe:SeCrEt" -i "input_uvc.so -y"

Hi Vladimir,

I did a manual launch and the webpage displayed an authentication for
username and password, but it didn't accept my account. I also tried the
root, but didn't make through. BTW, is the username and password which I
created in mini2440? Should be right? What is the default username and
password (if any)? Please advise.

Thanks,
Puma

Hello,


when you launch mjpg_streamer with password enabled, you should see
something like this:

 o: www-folder-path...: ./www/
 o: HTTP TCP port.....: 8080
 o: username:password.: UsErNaMe:SeCrEt
 o: commands..........: enabled

Navigating to the webpabge of the mjpg_streamer then shows the dialog to
enter username and password. Entering UsErNaMe as username and SeCrEt then
works. So, if you want to set custom username and password - replace
UsErNaMe:SeCrEt in the command line with something else.

Hi Vladimir,

It's great! The authentication is working well now with my own username and
password settings.

One thing I suggest to add to automate the mjpg-streamer is to have it
activated during booting in the mini2440. I mean, there is no need to type
and re-type the syntax (e.g.LD_LIBRARY_PATH="$(pwd)" ./mjpg_streamer -o
"output_http.so -w ./www -c
UsErNaMe:SeCrEt" -i "input_uvc.so -y") every time rebooting process is
being made in the mini2440. Or perhaps you have already done that in your
mini2440. If so, would you mind to share it or give me some ideas on how to
do it. I remember, in other linux system (e.g., DSL) the way to do is to
insert the syntax (e.g., /opt/lampp/lamp start) to file /opt/bootlocal.sh.
Please advise.

Thanks,

Hello,

just add this line to /etc/init.d/rcS and don't forget to add '&' at the
end.

Hi Vladimir,

On my first attempt, I tried to add the line to /etc/init.d/rcS without the
path as shown below inside the rcS file.

rcS
-----------------------------------------------------------------------
LD_LIBRARY_PATH="$(pwd)" ./mjpg_streamer -o "output_http.so -w ./www -c
UsErNaMe:SeCrEt" -i "input_uvc.so -y" "&"
-----------------------------------------------------------------------

I got an error message " /etc/init.d/rcS: line 69: ./mjpg_streamer: not
found" during re-booting.

On my second attempt, I put the path and add the line to /etc/init.d/rcS

rcS
------------------------------------------------------------------------
/home/puma/mjpg-streamer LD_LIBRARY_PATH="$(pwd)" ./mjpg_streamer -o
"output_http.so -w ./www -c UsErNaMe:SeCrEt" -i "input_uvc.so -y" "&"
------------------------------------------------------------------------
but this time a got a permission denied during booting.

/etc/init.d/rcS: line 69: /home/puma/mjpg-streamer: Permission denied

I gave permission chmod 777 to /home/puma/mjpg-streamer, but still a
permission denied prompted. Power down/up the mini2440 didn't make it
through. Please advise.

Thanks,
Puma

Hello,

you have to specify the full paths to the mjpg-streamer, i,e add following
line:

LD_LIBRARY_PATH=/home/puma/  /home/puma/mjpg-streamer -o
"output_http.so -w /home/puma/www -c UsErNaMe:SeCrEt" -i "input_uvc.so -y"

Hi Vladimir,

I haven't tried yet the latest info you provided as shown above since I was
a bit busy with the other set-up on the 2 USB cam. Anyway, I'll get to you
once I have done it probably tonight when I get back home.

I have another query on the same topic, but this time the user can be able
to change the password at the remote pc (client side) and not at the server
side as I did it before. Please advise.

Thanks,
Puma

Hi Vladimir,

I would like to know how can I change the password at the remote pc (client
side) instead at the server side?

Thanks,
Puma

>how can I change the password at the remote pc

you can :
1. login to mini2440 using telnet, and change the password
2. login to mini2440 using ssh, and change the password
3. take the source code of mjpg-streamer and add this functionality , it is
here: http://code.google.com/p/mjpg-streamer-mini2440/source/checkout 
or here (original): http://sourceforge.net/projects/mjpg-streamer/develop

Hi Vladimir,

Thanks to your reply and valuable information. I'll check that out and let
you know the result.

I guess I need to elaborate more on my query on changing the password at
the remote pc. What I mean is, the client at the remote pc can able to
change the password using "any internet browser" without login to the
telnet/ssh. Assuming the client doesn't have any technical knowledge on the
linux or windows system.

Thanks,
Puma
