I have been struggling (and making progress) on installing ZM 1.36 on an OpenSuSE 15.4 system. I got my copy from a community maintained repo for OpenSuSE and strongly suspect that there were/are problems with how the integrators set up ZM. I could provide a list of problems I found and had to find a fix for, if interested.

I have managed to get ZM to come up, and even display images from my cameras, but only for a short period of time. ZM will suddenly stop (mostly when viewing a live stream from a camera, but not always.) and return to the login page. A couple of observations I have noted, from the log files -

The first odd thing I see is that the apache-error.log file is constantly reporting (every few seconds while I am logged in and using ZM) "Login successful ..." messages. This indicates that behind the scene, ZM is having troubles keeping me logged in, and apparently it's attempts to keep me logged in eventually soon fails, causing ZM to log me out, and dumps me back to the manual login screen.

Also in the apache-error.log file I am seeing a lot of this error, for which I do not have a solution yet. I have not found where I could get the file wp-login.php -

Code: Select all

apache-error.log:[Wed Jan 04 13:53:56.941447 2023] [php7:error] [pid 21536] [client 130.61.143.194:46276] script '/usr/share/zoneminder/www/wp-login.php' not found or unable to stat

The second thing of concern to me is that the zm service itself terminates quickly after starting it up. It seems to last long enough to spawn a lot of sub-processes -

Code: Select all

nova:/var/log/zm # systemctl stop zm
nova:/var/log/zm # systemctl start zm
Job for zm.service failed because the control process exited with error code.
See "systemctl status zm.service" and "journalctl -xeu zm.service" for details.

Jan 07 16:30:31 nova systemd[1]: Failed to start ZoneMinder Video Surveillance System.

I have not found a real reason why zm.service is failing to start other than it appears (from looking at the code in zmpkg.pl) that neither stopping or restarting the zm service changes the state from "RUNNING". And because zmpkg.pl thinks the zm service is already running, it reports an error when
it tries to start the zm service again.

ASIDE NOTE: zmpkg.pl is dropping the reason for returning an error (Already running), into the bit bucket. This is bad programming practice, it should be logged at least, better yet reported to the user visually.

The following shows that even though zm.service failed to start, it at least spawned off a lot of child processes before failing.

Any ideas on how to get the zm.service and ZoneMinder's gui to run reliably? Much appreciate any and all offers of help, thanks in advance....

Marc..

P.S. It is very aggravating to spend time writing up a complex email, such as this one, only to find that the web server has timed you out, forces you to re-log in, and then drops everything you had typed up, on the floor. The one thing I remember most, from my computer science classes many many years ago, is that the first cardinal rule of good programming practices, is to NEVER NEVER NEVER lose user data! This web interface badly violates that rule!

I especially like the bit where you want to ‘find’ the file that hackers keep looking for.

LOL! It took me awhile to grok what you were trying to say Magic919, I am not familiar with wp-login.php files, not a Word Press user and didn't know that this is the name of the standard login script for Word Press sites. So just was reporting anomalies that I am seeing. OK I will knock that one off my list of things to worry about, and set my grep and fail2ban filters accordingly. The rest of my issues, that I reported still stand and I am in need of help/solutions. Thanks for your input... Marc

You already had a response from Isaac on your previous thread.

Either use an OS with a known good package or wait for Isaac.

Posted: **Mon Jan 09, 2023 8:36 am**

Magic919 - Granted. I started a new thread for a couple of reasons, I have gotten past the ZM_PATH_SOCKS issue that Isaac helped me with, and I have managed to make progress on getting ZM up and running under OpenSuSE. Since I am at a new roadblock I thought I would report my current state and see if anyone could help me with (perhaps have experienced and found solutions for) the new errors I am seeing.

Asking me to switch to a different OS is a bit extreme. It would require a lot of effort to grok an different variant of Linux, and then switch all the other dependencies of programs and services I am running, into the new environment. I know Isaac means well when he offered to take a look at OpenSuSE but I also know that he will also have to grok a lot about a different Linux environment, one that he is not use to. So I am reporting my progress, and will continue to study and look for solutions on my own as well. I think it is the best use of my time to keep searching for answers, asking new questions, etc while Isaac, you and perhaps others can help me achieve my goal of getting ZM running properly under OpenSuSE. I appreciate Isaac is planning to explore one path, if he gets the spare time cycles to do so, in the meantime there are other paths for me to explore also. Thank you for your thoughts, Marc...

If you don't mind spending your time on it, fair enough.

I'd suggest you look at running it manually, on the commandline, rather than as a service. Might reveal useful clues.

Hopefully it's the current version and you are not hitting bugs that have been fixed.

The wp-login thing as you know is someone hitting your site and scanning it for vulnerabilities.

The logout problem I suspect is due to inconsistency between the time zone set at the system level (hence mysql level), and what is set in php. System and php have to agree about the time zone, or else login sessions expire either immediately or after an hour or whatever.

Thanks iconnor for taking the time to read and respond to my request for help, much appreciated!

As for time zone settings, the file /etc/php7/apache2/php.ini has the following definition

Code: Select all

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

and timedatectl shows -

Code: Select all

# timedatectl
Local time: Tue 2023-01-10 16:12:17 PST
Universal time: Wed 2023-01-11 00:12:17 UTC
RTC time: Wed 2023-01-11 00:12:17
Time zone: America/Los_Angeles (PST, -0800)
System clock synchronized: yes
NTP service: active
RTC in local TZ: no

It appears to me that these are showing PHP and my local system is using the same time zone... Marc....
