Socket issue

[kjakman]

Hi,

I have been struggling with the error:

ERR [socket_sendto( /var/run/zm/zms-101732s.sock ) failed: No such file or directory],

for two days, and eventually gave up on the smaller server, and did a fresh of install of 1.29 on a fresh Ubuntu 16.04 with 4GB memory, as per
wiki.zoneminder.com/Ubuntu_Server_16.04_64-bit_with_Zoneminder_1.29.0_the_easy_way

It briefly worked (I could see a live stream from my Foscam FI9853EP), but now the error is back, and I did not change anything in the meantime.

I'm completely stumped. Turned off UFW just in case. Added 8GB swap.

My PATH_ZMS is /zm/cgi-bin/nph-zms
My zoneminder.conf is

Code: Select all

ScriptAlias /zm/cgi-bin "/usr/lib/zoneminder/cgi-bin"
<Directory "/usr/lib/zoneminder/cgi-bin">
    Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
    AllowOverride All
    Require all granted
</Directory>

Alias /zm /usr/share/zoneminder/www
<Directory /usr/share/zoneminder/www>
  php_flag register_globals off

  <IfModule mod_dir.c>
    DirectoryIndex index.php
  </IfModule>
</Directory>

<Directory /usr/share/zoneminder/www/api>
  AllowOverride All
</Directory>

In the system log, I see:

(Yes, the camera username/password is correct)

I see sockets appearing and disappearing, but still get the error, and no live stream.

Code: Select all

root@zm:/var/log# ls -l /var/run/zm
srwxr-xr-x 1 www-data www-data 0 May 31 14:51 zmdc.sock
-rw-r--r-- 1 www-data www-data 4 May 31 14:51 zm.pid
-rw-r--r-- 1 www-data root     0 May 31 15:24 zms-080394s.sock

My camera settings are good, I did briefly see the live stream.
I've started and stopped the service (starting zoneminder first, then apache)

I've read all the documentation and forums I could find, but completely stuck. Any input is much appreciated.

Socket sendto errors are not an indication that something is wrong in your system. I see them all the time when several are viewing montage at the same time. Restart your web browser or refresh the browser window. I have my users set up on Firefox with an add on called Refresh Every that I have set to refresh the window every 5 minutes.

So, for the most part you can ignore socket sendto errors if everything else is working. And you may be better off upgrading to ZM 1.30.4.

Thank you for your reply. It is an issue however, because I cannot see the video stream.
I started out with 1.30.4 on the first server with less memory, same issue, which is why I tried a fresh install with 1.29
I just upgraded to 1.30.4 on the new server, still no stream visible, with this in the log:

CGI is enabled in apache and check the PATH_ZMS is set correctly.

I've tried with two other cameras following exact instructions as per wiki, same issue.
Not sure how to troubleshoot further...

Thanks, Kjetil

Update: I saw "Error, unable to authenticate user" when using zmNinja, and changed AUTH_RELAY to "none"
as per github.com/ZoneMinder/ZoneMinder/issues/1552

Not sure if it's related, but atm the stream is working in zmNinja as well as all browers simultaneously (Chrome, Safari, FF)

Thanks, Kjetil
