Zone setup - no image

liderbugzm · Post by **liderbugzm** » Sun Nov 26, 2006 5:27 pm

Linux FC-4. Camera & events are working. I can watch an event. However when I click on Zones the window pops up - blank (broken img). If I copy an image from the events dir to cam-Zones.jpg - 'then' I have a image and can define an area (I think). This is not what I read in the Manual. It seems to, well ... automagicly appear.
A pointer or two please.

Tks

check your logs its usually a permission problem on the images folder

liderbugzm · Post by **liderbugzm** » Sun Nov 26, 2006 5:43 pm

Permissions on the image subdir are 777. Also if I see ".../zm_manual/images/console2.png" right the camera name is a link - except on my page, it's just the name
10. deck1 Modect /dev/video1 (2) 12
Not sure how to show as links but "deck1" ... ain't.

thanks

As root - command line
/usr/local/bin/zmdc.pl check returns "running" as apache - stopped
and when zm_funcs.php:daemonCheck runs zmdc.pl check the line
my $server_up = connect ( CLIENT, $saddr ); returns 1, operation not permitted.
If I set the return in zm_func to "running" my camera name becomes a link. I can pop up the monitor window. I haven't been able to google or forum the ans. I've checked permissions, env. Drawing a blank.

I'm getting the same problem... any ideas?

Manwe · Post by **Manwe** » Tue Nov 28, 2006 2:46 am

additionally I've found an error in the zmdc.log file:

28/11/06 03:30:12 008921 zmdc[501].ERR ['zmc -m 1' exited abnormally, exit status 255]

that's the only error I have found in all logs.

Here's one problem I'm tracking. I start ZM, wait a few seconds then click
on one of the "zone" links and up pops the window - empty.
I added this (line 262 in zm_monitor)
Debug( 1, ( "1. %x %d %o %d", (config.shm_key&0xffffff00)|id, shm_size, IPC_CREAT|0700, errno ));
just after the shmget . The following is the DBout.
Notice the line I've marked <<< calling a zmu sans monitor.

Going to be late to work - more later.

Errno 13 is permission denied. Can you check using ipcs -m that your shared memory has not been created by root or anything like that?

In zm_html_view_zones.php right off the bat the code does:
...... exec ("zmu -m $mid -z") >>>>>> NOT!

I can do exec ("ls /etc") and it returns a list a mile long, date, echo HelloWorld
FINE. zmu - nothing. I can put exec (zmu in a tst.php script and run it (http:127../tst.php) works great.

The $@^!#$ thing won't run from within zm_html_view_zones.php. I've tried php:SafeMode, Unsafemode - HELP!!!!!!! Out of ideas. Forehead bleeding..........

http...tst.php - zmu does not run - again everthing else does

also in zm_funcs.php: function daemonCheck gets "stopped". If I run it from the command line, "running" ??? Something in ENV ???

SELinux SELinux SELinux SELinux SELinux SELinux

I had to run "system-config-securitylevel" and tell it Don't worry about httpd"

I now have 206W1-Zones.jpg in zm/images.

ave huge headache.

php.net : exec : 3d post

So the reason exec ("ls") etc works and exec ("zmu") doesn't is because zmu is using sockets and SELinux checks for http pages using sockets and says "Not today!". Turning off HTTP in the selinux.conf seems to leave a security hole. Maybe one of these days we can say CheckHTTP, except: zma, zmb ,mzc, ...

Thanks for letting us know. It may be worth adding this to the FAQ I think, though it doesn't get asked very often as such. But obviously is a big pain when it happens. I just automatically disable selinux on any box I get, which is probably a bad habit.

Thought: FAQ's need ... faq:FC4, faq:Ubunta, faq:MS(ucks) [just kidd'n just kidd'n]

Also I posted the question at

The ans, Yup, thats the way it works.
