ZM 1.23.3 and Ubuntu 8.10

wisekki · Post by **wisekki** » Sun Jan 25, 2009 10:32 am

So is it really true that ZM doesn't work with Ubuntu 8.10?

I've tried everything, compiled from source, installed from repository and every goddamn time I get errors about shared memory not being valid and so on...

So is there anybody who has zm running on intrepid? I've even switched from 64bit to 32bit but that didn't help at all...

Or is this all result of v4l2 drivers? If so then nobody's running zm with default configuration of 8.10?

Hello.

ZoneMinder works fine on Ubuntu 8.10, be it 64bit or 32bit, source or package.
I am putting together a wiki entry for this exact setup, which you can find at http://www.zoneminder.com/wiki/index.php/Ubuntu_8.10.

Hope this helps.

Geez finally someone

Can you please tell me a little bit how you did it? I did a fresh Ubuntu 8.10 install and then I installed zoneminder from package, started it and added one monitor.

What kind of camera setup are you using? usb-cams or some hightech? And you're not getting these shared memory errors/warnings?

Can you see your "zm-memory-key" with ipcs?

Thnx already for your answers

Hey there, no problem.

I am using a fresh Ubuntu 8.10 64 Bit Minimal Server install. If you are using 32bit and / or the standard server install, it shouldn't matter.

I am 8 640x480 24bit color analog cameras on my most recent build, with 2x 4 port bttv cards.

Code: Select all

root@tpp-camera:/var/log# cat /etc/modprobe.d/bttv
options i2c-algo-bit bit_test=1
options bttv card=102,102,102,102,102,102,102,102

I have also 16 IP cameras on another build.

I only get shared memory errors until I up the shared memory size:

Code: Select all

root@tpp-camera:/var/log# tail /etc/sysctl.conf
kernel.shmall = 268424446
kernel.shmmax = 268424446
vm.swappiness = 90        #ignore this
vm.dirty_background_ratio = 3        #ignore this
root@tpp-camera:/var/log#

Code: Select all

root@tpp-camera:/var/log# ipcs -m

8 segments for 8 cameras. yay.

Specifically, what kind of problems are you having?
On my servers (on which I install ZM from source), all ZM related files and directories are owned by www-data (the apache2 user). This includes the binary files (/usr/bin/zm*) , the files in /var/lib/cgi-bin, the conf file and any files in /usr/share/zoneminder. (My paths are different, but they should be right for your system.) I am not sure how Ubuntu sets up permissions for a packaged install...

Thnx for the quick reply. I'm using 4 usb-cams, all of them logitechs, using gspca_zc3xx and gspca_main modules. These cams work perfectly with mplayer...

When I add the first camera I simply get this:

Code: Select all

zmwatch[11094].ERR [Can't get shared memory id '7a6d0001', 1: No such file or directory]
zmwatch[11094].INF [Restarting capture daemon for Koti1, shared memory not valid]

And it keeps repeating that all day long

ZM says that ZM_SHM_KEY is 0x7a6d0000.. so it should be right... I've no key print for zm in shared memory segments...

I've set shmall and shmmax to:

Code: Select all

kernel.shmall = 134217728
kernel.shmmax = 134217728

I'm kinda lost here.. with ubuntu 8.04 zm worked like a wet dream

Post by **kylejohnson** » Tue Jan 27, 2009 7:44 pm

I think I got that error when zoneminder was running as the root user. After changing the owner of the binaries to www-data and restarting the service, things started working.

What user is ZM running as?

Code: Select all

ps axu | grep zm

wisekki · Post by **wisekki** » Tue Jan 27, 2009 8:05 pm

It's running as www-data...

Post by **kylejohnson** » Tue Jan 27, 2009 8:18 pm

Reading over a few other posts:
1: Did you ever start ZM as root? Do you have any .sock files in /tmp that are owned by root?
2: Did you start ZM from /etc/init.d, or from the web interface? Try killing all the zoneminder processes, and then starting from the web interface.
3: Are there any errors in zmdc.log?
tail -f /tmp/zm*
Also check you messages log as you might find something more discriptive there. /var/log/messages
4: Where is nph-zms and zms installed at? Either /usr/lib/cgi-bin or /usr/share/zoneminder?[/list]

wisekki · Post by **wisekki** » Tue Jan 27, 2009 8:39 pm

Again thnx for trying to help me.. I really appriciate it

I've tried with root and www-data and i've deleted everything from /tmp.. killed everything so ps axu doesn't show anything and i've started zm from /etc/init.d and from the web interface.. Every time the same error:

Code: Select all

01/27/09 22:31:19.238487 zmwatch[12504].INF ['zmc -d /dev/video0' starting at 09/01/27 22:31:19, pid = 12623]
01/27/09 22:31:19.238704 zmwatch[12504].ERR [Can't get shared memory id '7a6d0002', 2: No such file or directory]
01/27/09 22:31:19.238762 zmwatch[12504].INF [Restarting capture daemon for Koti2, shared memory not valid]

nph-zms and zms are at /usr/lib/cgi-bin/

Okay I have some extra errors at syslog now after fiddling with the system:

Code: Select all

Jan 27 22:36:46 router zmc_dvideo0[13305]: ERR [Sync failure for frame 1 buffer 2(1): Invalid argument]
Jan 27 22:36:46 router zmc_dvideo0[13305]: ERR [Failed to post-capture monitor 0]

Jan 27 22:36:47 router kernel: [192286.059743] zc3xx: probe 2wr ov vga 0x0000

And before that it said permission denied /dev/video0 so I just chmodded them to 777

Post by **kylejohnson** » Tue Jan 27, 2009 8:46 pm

I added www-data to the video group to get around the permission denied errors.

Can you query your cameras doing zmu -q -v --device /dev/video0? I think the syntax is right!

Also, not sure if it matters, but by which user are your zm binaries owned?

wisekki · Post by **wisekki** » Tue Jan 27, 2009 8:52 pm

hehe okay how do I add www-data to the video group? (this is just a sideq.

Code: Select all

zmu -q -v --device /dev/video0

And my cams work with mplayer or xawtv... using v4l2..

ZM binaries are owned by root.

Post by **kylejohnson** » Tue Jan 27, 2009 11:58 pm

sudo usermod -a -G video www-data] might do you.

I _vaguely_ recall that when changing the owner of my binaries from root to www-data, and then restarting the processes, shared memory started working.

wisekki · Post by **wisekki** » Wed Jan 28, 2009 5:12 am

Yea I think shared memory is no longer the prob here. Now it's something like:

Code: Select all

Jan 28 07:08:15 router kernel: [222973.700432] zc3xx: probe 2wr ov vga 0x0000
Jan 28 07:08:16 router zmc_dvideo0[22418]: ERR [Sync failure for frame 1 buffer 2(1): Invalid argument]

Jan 28 07:08:22 router zms[22438]: ERR [Got signal (Floating point exception), crashing]

Again I have no idea what so ever

Hopefully you or someone knows what to do

Well those errors don't look good, and a google search returns nothing... Hopefully another member has seen these and can help you, because I can't!

wisekki · Post by **wisekki** » Wed Jan 28, 2009 3:44 pm

I know man i know

And I've fiddled with zm and ubuntu 8.10 since ubuntu's release.. it just refuses to work
