live veiw YES on localhost, NO on others

[zd59]

Hello!

My config:
Zoneminder-1.30 on Debian stretch ( 4.8.0-2-amd64 #1 SMP Debian 4.8.11-1 (2016-12-02) x86_64 GNU/Linux)
Apache/2.4.25

The problem:
All works on localhost, whrere all is installed. I can watch live video and events video in Firefox, none in Konquerror.
The problem is, that live video can not play on other computers on LAN, but events video plays OK. Tried Firefox on Linux (slackware) and Firefox & internet Explorer on Windows. Internet Explorer give me a Java app security approval window, and after click to run I get "Java.net.UnknownHostException:HOSTNAME" error in the place of a video window. The same case is on my Android phone (live or event video not working).

I Cambozolla.jar is at right place with right permissions (0755)
PATH_ZMS = /zm/cgi-bin/nph-zms which is in zoneminder.conf:

MPEG_LIVE_FORMAT = tested mpg mpeg wmv asf avi mov swf 3gp mp4
WEB_H_CAN_STREAM = tested Auto, yes, none

Loglevels:

log window in zoneminder gui console & logs in /var/log/apache2 show no signs of errors.

Must point out, that none of the browsers (Firefox or IE) warns about any missing plugins.
Any idea, what to try?

regards to Zoneminder developers & comunity, incredible work done!

Check the Apache /etc/apache2/sites-enabled directory that you have a correct virtual host configuration to allow Apache to serve the ZM streams by setting the right permissions for the /cgi-bin when accessed via LAN or Internet and not just localhost.

Also checked again: no lines regarding video stream error/warning in apache2 error.log access.log or zoneminder log screen.
The only sign of video watch request was in /var/log/apache2/access.log:
10.200.200.10 - - [19/Jan/2017:09:48:51 +0100] "GET /zm/index.php?view=watch&mid=2 HTTP/1.1" 200 2532 "http://10.200.200.20/zm/index.php" "Mozilla/5.0 (Windows NT 10.0; WOW64; rv:50.0) Gecko/20100101 Firefox/50.0"

The apache2 LogLevel warn
The system log (/var/log/system) also logs (LOG_LEVEL_SYSLOG = INFO) and there is no sign of any warning or error. Just Capturing and Analysing lines.

What bothers me the most is the fact, that I can watch events video and NOT live video. What is the difference between both, if I set the same settings in options -> images in Zoneminder console settings?

Regards!

I think you are "stretching" things a bit trying to get a development version to work. However, I am in process of loading up Stretch to see what I can come up with. Stay tuned...

[rockedge]

try using this in /etc/apache2/sites-enabled 000-default.conf -> ../sites-available/000-default.conf

Code: Select all

DocumentRoot /var/www/html
AddHandler cgi-script .cgi .pl
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined

Since it works with localhost it could be that /cgi-bin is not configured to be accessible via network.
Or in your PATHS config in ZM Options is not set to the correct /cgi-bin
It could be that it is using the wrong alias /cgi-bin..... you have two.

Code: Select all

ScriptAlias /zm/cgi-bin "/usr/lib/zoneminder/cgi-bin"
ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/

Well, my test install works just fine. I did not set up a desktop version and did the bulk of the Zoneminder install from Putty on a Windows PC. I suspect you used a desktop install which may contain a firewall that is causing your issues.

Here are the basic steps I used:
Debian 9 LAMP Zoneminder

net install CD install only web server, SSH server and standard system utilities from tasksel


Login and become root

Install additional LAMP components

apt install apache2 php mysql-server php-mysql

Install Zoneminder

apt-get install zoneminder


Create Zoneminder database in MySQL (Note: this also creates the default Zoneminder user and permissions in MySQL)

mysql -uroot -p < /usr/share/zoneminder/db/zm_create.sql

mysql -uroot -p -e "grant all on zm.* to 'zmuser'@localhost identified by 'zmpass';"

mysqladmin -uroot -p reload

Set permissions of /etc/zm/zm.conf to root:www-data 740

chmod 740 /etc/zm/zm.conf

chown root:www-data /etc/zm/zm.conf

Enable Zoneminder service to start at boot

systemctl enable zoneminder.service

Add www-data to the sudo group (to enable use of local video devices)

adduser www-data video

Start Zoneminder

systemctl start zoneminder.service

Check to see that Zoneminder is running

systemctl status zoneminder.service

Enable CGI and Zoneminder configuration in Apache.

a2enmod cgi

a2enmod rewrite

a2enconf zoneminder
Add timezone to PHP

nano /etc/php/7.0/apache2/php.ini

Search for [Date] (Ctrl + w then type Date and press Enter) and make changes as follows for your time zone

[Date]
; Defines the default timezone used by the date functions
; http://php.net/date.timezone
date.timezone = America/New_York

Ctrl+o Enter to save

CTRL+x to exit

Restart Apache

service apache2 restart

[bbunge]

Had to make an addition to my procedure to get the API to work. See:

https://wiki.zoneminder.com/Debian_9_64 ... e_Easy_Way

try using this in /etc/apache2/sites-enabled 000-default.conf -> ../sites-available/000-default.conf

Thank you rockedge for the tips.
Changes you suggested did not helped.
I do not have any firewall on the server nor on client - home LAN clean, firewall on the WAN router only.
After applying your suggestions and restarting apache2 & zoneminder, I found some errors in zoneminder log regarding streaming.
Maybe this is the key.

and many more swap files. I think, they were created on sucessfull live view on localhost only. Today I checked, were not created on remote access.

Thank you for your time.
Regarding above, have you any new advice?

Regrads!

reinstall Debian and use the new instructions on the WIKI for Debian 9

Hello again!

Discovered very strange behaviour, and so a partial solution to the problem described at my first post.
The member of this post "Basketcase" on Tue Oct 18, 2016 8:41 am posted:
viewtopic.php?f=36&t=25382&p=97008&hili ... eam#p97008
Between the lines I found out, that CGI script, that is responsible for a streaming a live video works coorectly only when in the browser the URL for the zoneminder is its name. When you write IP instead of a name, there is no live video stream.
As I do not have a DNS at home, I had always written IP (http://10.200.200.200/zm).
As the problem is mentioned in the post above, I set a line in a host file (10.200.200.200 video-surveillance) on remote computer, then in Firefox http://video-surveillance/zm, and miraculously now I can watch live video from camera.
In the servers option in zoneminder there must be a line with a server name, in my case "video-surveillance", and user authentication in zoneminder must be OFF.

Hope that one of the developers will read this post, to correct this misbehavior. At this point I can not watch live video on Android, as host file is not accesible.

Greetings to all.

[zd59]

Hi!

Developers: no answers for the above?
Simple question: why no live video, if Zoneminder is addressed by IP instead of its name in web browser?
No home DNS, so if hosts file "resolve" IP to name, then live video works in browser. This can not be done on Android without rooting it. So no solution for Android.

Regards.

[rockedge]

I still think you need to configure the web server correctly. The line you wrote

I set a line in a host file (10.200.200.200 video-surveillance) on remote computer

leads me to believe you configured the virtual users block incorrectly. Or you are using the multi-server options? Because it is confusing as to what is going wrong as you describe it.

[SteveGilvarry]

Zd59 I will try and replicate, to confirm http://localhost works but http://xxx.xxx.xxx.xxx doesn't? I normally only use the IP and don't have a localhost GUI. On my phone at the moment but I assume all your apache conf is above, if not can you add it.
Thanks
Steve

Hello!

I attached apache2.conf - the same as installed by corresponding Debian 8 package and (if) changed by zoneminder 1.30 installation/configuration.
Rem: .txt at the end as forum do not accept attacments ending ".conf"

Pointing out, that this machine is dedicated to ZM and no other packages were installed to spoil Apache or else.

Unless you have multiple servers it should be blank. I am concerned you have turned all the knobs and dials now so getting you back to a default configuration, which with Firefox should work fine. I don't promise anything works on IE. Might be an idea to start over and don't change anything not in BBunge's wiki guide.
