FUBAR after last update - Arch

[Onion]

Hi

I have had no end of problems lately with updating my system and Zoneminder breaking but after the last update it is totally broken and I can not fix it.

I was on version 1.30 and I got this error after the update.

Code: Select all

Sep 28 12:44:06 arch zmwatch[1541]: ERR [Can't open memory map file '/dev/shm/zm.mmap.1': Permission denied] Sep 28 12:44:06 arch zmwatch[1541]: INF [Restarting capture daemon for Monitor-1, shared data not valid] Sep 28 12:44:06 arch zmdc[952]: INF ['zmc -m 1' starting at 18/09/28 12:44:06, pid = 3240] Sep 28 12:44:06 arch zmdc[3240]: INF ['zmc -m 1' started at 18/09/28 12:44:06] Sep 28 12:44:06 arch zmdc[952]: ERR ['zmc -m 1' exited abnormally, exit status 127] Sep 28 12:44:16 arch zmwatch[1541]: ERR [Can't open memory map file '/dev/shm/zm.mmap.1': Permission denied] Sep 28 12:44:16 arch zmwatch[1541]: INF [Restarting capture daemon for Monitor-1, shared data not valid] Sep 28 12:44:16 arch zmdc[3251]: INF ['zmc -m 1' started at 18/09/28 12:44:16] Sep 28 12:44:16 arch zmdc[952]: INF ['zmc -m 1' starting at 18/09/28 12:44:16, pid = 3251] Sep 28 12:44:16 arch zmdc[952]: ERR ['zmc -m 1' exited abnormally, exit status 127]

I then tried a clean install using 1.32, fresh install PHP and running under Nginx, removed apache.
Same error:-

Code: Select all

2018-09-30 21:20:31 zmwatch 21857 ERR Memory map file '/dev/shm/zm.mmap.1' does not exist. zmc might not be running. zmwatch.pl
2018-09-30 21:20:27 zmdc 21797 ERR 'zmc -m 1' exited abnormally, exit status 127 zmdc.pl

I only updated the system to get this error, I did not change anything in my camera, zoneminder php, apache. here is a list of the packages which were updated:

Anybody have a clue what has happened?

Many thanks

Norally zm runs are the user that apache runs as, which is often www-data or apache on redhat based distros.

Since you are running nginx that may be something you need to be aware of.

In any event, zmc and the other perl scripts need to be able to create and access files at /dev/shm

[Onion]

Thanks iconnor for your reply

I had a look at the Arch guide for both Apache and Nginx and see both users are http.

I can create files in /dev/shm as user http

Code: Select all

ian@arch:/dev/shm$ l
-rw-r--r-- 1 http http    0 Oct  1 16:23 zonemindertest.txt

Apache was working but stopped after the Linux update something has busted it and I have no idea what im looking for.

Is there any clues to what this actually means is there a debug mode I can use to find out?

Code: Select all

zmwatch 21857 ERR Memory map file '/dev/shm/zm.mmap.1' does not exist. zmc might not be running. zmwatch.pl

Hey,

I can't help but ask, did you upgrade on your own or have you used the new PKGBUILD I've posted in the AUR page's comments?

If the former, then make sure that ZoneMinder itself is launched as user 'http' by systemd (or whatever means you use to launch it) and then verify that when ZoneMinder is running there is actually a file /dev/shm/zm.mmap.1 and that it has the correct permissions, i.e. http:http.

If the latter, and judging by the second error you posted (ERR 'zmc -m 1' exited abnormally, exit status 127 zmdc.pl) this seems to be the case, then this is simply a ZoneMinder bug. See here:

https://github.com/ZoneMinder/zoneminder/issues/2184

The fix (a workaround really) has already been upstreamed and will probably be included in the next ZoneMinder release (1.32.1). In the meantime you can apply the fix yourself by editing the file '/usr/bin/zmdc.pl' and changing line 485 from

'my $fd = 0;'

to

'my $fd = 3;'

I found the problem with /dev/shm I ran the zmc -m 1 as user http and found libidn was the issue.

I fixed that but now I see no image in the monitor page, but it intermittently says it is capturing but there is no streaming display , just lots of "ERR Unable to send packet at frame 1667: Resource temporarily unavailable, continuing zm_ffmpeg_camera.cpp"

2018-10-01 19:41:42 zmc_m1 2818 ERR Unable to send packet at frame *: Resource temporarily unavailable, continuing zm_ffmpeg_camera.cpp 240

I changed the file/usr/bin/zmdc.pl but no fix for streaming in ZM, I can make a movie using

ffmpeg -i "rtsp://un:pws@***.***.*.**:***/h264Preview_01_main" -vframes 1000 out.avi

[Nocifer]

What was the problem with libidn and how did you end up fixing it? And this new error about packet frames, have you encountered it before? I'm asking because I was able to fix the /dev/shm/ issue by simply changing that line in /usr/bin/zmdc.pl, and now ZoneMinder works correctly. Perhaps messing around with libidn broke something else?

[Onion]

I think there was a problem from running update must have been interupted as after I reinstalled libidn the /dev/shm error went away and I could start zmc -m 1 as http.

Now I got rid of the "ERR Unable to send packet at frame *: Resource temporarily unavailable, continuing zm_ffmpeg_camera.cpp 240"

I changed the band width to medium and that made them go away.

I cannot get the monitor to display the stream and I have no errors!!!

I am guessing this is pointing towards the nginx config file?

This is in /etc/nginx/sites-enabled/zoneminder.conf
server {
listen 8095;
server_name localhost;

root /srv/zoneminder/www;

location /cache {
gzip off;

root /var/lib/zoneminder;

}
}

Is there a command line I can run to see the stream from zmc?

[Onion]

I can view the stream from zms in vlc with

http://localhost:8095/cgi-bin/nph-zms?m ... uffer=1000


So thats good just need to work out why zoneminder is not displaying the stream?

[Nocifer]

The AUR package has just been updated. Please upgrade to the latest version and see if your issues are resolved.

No didnt fix it, no image in monitor just lots of errors as before
