zmtrigger.pl configuration

[coinageboy]

Hi,

I am trying to use external trigger from Axis 211A to zmtrigger.pl runing Ubuntu server 64 12.04.

zmtrigger.pl is running but the Axis camera test to connect shows following error:

Connection failed:
502 Bad Gateway
The CGI was not CGI/1.1 compliant.

I tried to connect from another machine using telnet, port 6802 and it connects fine.

Also, zmtrigger.pl sometimes exits with following message:

variable is not a string at /usr/share/perl5/ZoneMinder/Memory/Mapped.pm line 109.

Any ideas??

You have to compile zm without mmap...thats work for me.

Did you solved you problem about ZM closing the connection via Telnet after some minutes connected?

Still observing the behaviour of this bug.

When I log into the port 6802, the telnet session dies after +/- 10 minutes. After a few retries, the system refuses to accept a new login...

Because of this problem my Zoneminder is missing major events - the TCP server probably crashes when the cameras and sensors start hitting. It restarts later, but the major event is lost..

I am polishing my Perl skills as I intend to figure it out.

If anybody tried to debug zmtrigger.pl, I am all ears to hear about it...

I'm not experienced in ZM or Linux. How can i do that?
In the instructions i followed to install zoneminder i have these steps involving mmap:

Code: Select all

######################
#Install Perl Modules#
######################

perl -MCPAN -e shell

install CPAN

exit

perl -MCPAN -e shell

install YAML PHP::Serialization Module::Load X10::ActiveHome

install Sys::Mmap

exit

It's needed to remove anything? Or just compile zoneminder without it?

AND

Code: Select all

#####################
##Install Zoneminder#
#####################

cd /usr/src && wget http://www2.zoneminder.com/downloads/ZoneMinder-1.24.2.tar.gz

tar -xvzf ZoneMinder-1.24.2.tar.gz

cd /usr/src/ZoneMinder-1.24.2/src && nano zm_utils.cpp

#Insert the following line after other includes,then Ctrl-o to save, Ctrl-x to exit nano
#include <cstdio>

cd /usr/src/ZoneMinder-1.24.2 && \ 
./configure --with-webdir=/var/www/zm --with-cgidir=/usr/lib/cgi-bin \
ZM_DB_HOST=localhost ZM_DB_NAME=zm ZM_DB_USER=zmuser \
ZM_DB_PASS=zmpass ZM_SSL_LIB=openssl --enable-debug=no \
--with-webgroup=www-data --with-webuser=www-data --enable-mmap CPPFLAGS="-D__STDC_CONSTANT_MACROS ${CPPFLAGS}"

autoconf

aclocal

automake

make

mysql -u root -p < db/zm_create.sql
#Password that is requested is Mysql root password that was entered during install, not your ubuntu password.

mysql -u root -p

grant select,insert,update,delete on zm.* to 'zmuser'@localhost identified by 'zmpass';

quit

make install

I remove "--enable-mmap", right?

I have zoneminder already installed, so i can do this step again without any uninstallation?

Thank you.

Problem solved. Now zmtrigger works correctly with telnet input strings.

Just reinstalled Zoneminder without mmap.

It was just needed to change the command used to install ZM when appears "--enable-mmap" to "--enable-mmap=no".

Before re-installed ZM, I needed to drop the zm.sql database (via webmin). I did a backup and restore.

I am glad to see that someone figured this one out.

I still consider this problem a MAJOR BUG in Zoneminder.

[sj3fk3]

I totally agree.. This is a MAJOR BUG!

After a couple of triggers I get:

$ /usr/bin/zmtrigger.pl
variable is not a string at /usr/share/perl/5.14.2/ZoneMinder/Memory/Mapped.pm line 113.

For those who are using my zoneminder ppa, and update to libsys-mmap-perl is there which should fix the problem. All others should reference upstream
