Camera shows no picture. Socket does not exist

Post by jannnfe »

Hello,
I'm trying to get my new camera with Zoneminder to run for days. I already have as much as everything I have found on the internet to get zoneminder to run.
I have installed zone minder like this: https://wiki.zoneminder.com/Ubuntu_Serv ... e_easy_way

The camera settings think I am right in zoneminder. It is the Wanscam JW0011 camera and with another service the camera with the same settings shows a picture.

I'm not sure if the connection to cgi-bin is correct in my system. I have however also still no possibility found this out.
I have already changed the PATH_ZMS to /zm/cgi-bin/nph-zms

In ZoneMinder log i get this errors:

Code: Select all

Socket /var/run/zm/zms-337020s.sock does not exist. This file is created by zms, and since it does not exist, either zms did not run, or zms exited early. Please check your zms logs and ensure that CGI is enabled in apache and check that the PATH_ZMS is set correctly. Make sure that ZM is actually recording. If you are trying to view a live stream and the capture process (zmc) is not running then zms will exit. Please go to http://zoneminder.readthedocs.io/en/latest/faq.html#why-can-t-i-see-streamed-images-when-i-can-see-stills-in-the-zone-window-etc for more information

Code: Select all

Unable to get response, disconnecting

But on the other hand I get these messages in the log. So actually it should work?

Code: Select all

Garagentuer: 1000 - Capturing at 23.26 fps
Garagentuer: 2000 - Capturing at 22.73 fps
This is my zoneminder.conf in apache2:

Code: Select all

# Remember to enable cgi mod (i.e. "a2enmod cgi").
 ScriptAlias /zm/cgi-bin "/usr/lib/zoneminder/cgi-bin"
<Directory "/usr/lib/zoneminder/cgi-bin">
    Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
    AllowOverride All
    Require all granted
</Directory>

Alias /zm /usr/share/zoneminder/www
<Directory /usr/share/zoneminder/www>
  Options -Indexes +FollowSymLinks
  <IfModule mod_dir.c>
    DirectoryIndex index.php
  </IfModule>
</Directory>

<Directory /usr/share/zoneminder/www/api>
    AllowOverride All
</Directory>

I have already done a2enmod cgi and its saying its running
I hope someone can help me to bring my camera to run.
Thanks!

Look in either

/var/log/apache/error_log or /var/log/httpd/error_log

whichever you have, and see what error is showing up when you call nph-zms.

That should be a hint what isn't configured correctly -- which is usually what this is.

Not quite. 'Client denied by server config' is the important sentence there, and it means that your Apache configuration is messed up somehow.

in my servers (ubuntu and debian), usually i do this:
cd /usr/lib/cgi-bin
ln -s /usr/lib/zoneminder/cgi-bin/zms zms
ln -s /usr/lib/zoneminder/cgi-bin/zms nph-zms

This will link zoneminder cgi to apache cgi.
Remember to set correct permissions with chmod!

I get this:

Code: Select all

nph-zms
root@homeserver:/usr/lib/cgi-bin# ln -s /usr/lib/zoneminder/cgi-bin/zms zms

nph-zms  zms
The ln -s /usr/lib/zoneminder/cgi-bin/zms nph-zms failed.
And what are the right permissions to set?
Thanks! :)

Hi all,
I have found this on another board.

https://bugs.launchpad.net/ubuntu/+sour ... ug/1159361

I have the same issue as you. It seems that the problem is the authentification.
I have set the AUTH_RELAY to <none> in OPTIONS > SYSTEM and it works.
The question is ZM secure whith this configuration ?

If you followed the install instructions in the WIKI to the letter you should have a working Zoneminder. Mis one step and your system will be toast!

As for the camera setup you should use ffmpeg with modern cameras. Get the video to show in VLC, note the access string and reported resolution, transfer those settings to Zonemimder and voila! Your system will work!!!

You may be ahead to reinstall Ubuntu server or minimal system then do Zoneminder by the numbers again. Add LAMP from tasksel at initial install or afterwards and it will configure itself to work. Try not to waste time with obscure changes recommended by other web sites. I run these installs often to insure they work!

Edit: I just noticed a well meaning person made some changes to the WIKI instructions. I've undone their changes but am unable to test the install as my test computers have not arrived back home from an unsuccessful family move. Hope to be able to get you firm info by the weekend.

Thanks for your reply.
I followed this instructions to install my camera: https://wiki.zoneminder.com/Wanscam_FR4020A2_Out

But i think i find the problem of not getting a video stream and for the error.
When I open the View Window of my camera in zoneminder and i right click on the video element and open it in a new tab i get this message:

Code: Select all

Forbidden
You don't have permission to access /zoneminder/cgi-bin/nph-zms on this server.
I found that same problem here but i can't figure out what i have to do to fix the permission problem

Jannnfe: "/zoneminder/" is an unusual thing to see in that pathname; it's customarily /zm/.

Did you pick /zoneminder/ in your install on purpose?

In my /etc/apache2/conf-enabled/zoneminder.conf i now have this Alias:
ScriptAlias /zm/cgi-bin "/usr/lib/zoneminder/cgi-bin"

And my PATH_ZMS is now /zm/cgi-bin/nph-zms but same permission Problem as described above.
I get also in the log no error message, except when I open the window in which the stream of the camera should run.

Check the filesystem permissions all the way along the path to
