fresh simplenas image on a Banana Pi. (wheezy) Everything wirks and is updated, omv2.2.4

Installing this plugin works and it shows in the sidebar. But I cant access any tabs in the CUPS webinterface or add a printer over omv. Example Error-log for the admin page: ​D [22/May/2016:21:54:16 +0200] [CGI] Started /usr/lib/cups/cgi-bin/admin.cgi (PID 10550) I [22/May/2016:21:54:16 +0200] Started "/usr/lib/cups/cgi-bin/admin.cgi" (pid=10550) D [22/May/2016:21:54:16 +0200] cupsdSendCommand: 14 file=15 D [22/May/2016:21:54:16 +0200] PID 10550 (/usr/lib/cups/cgi-bin/admin.cgi) stopped with status 113 (Permission denied) D [22/May/2016:21:54:16 +0200] cupsdWriteClient: 14 Closing because Keep-Alive disabled

It seems there is a permission issue. CUPsd is started as root, most cups files are 755 and owned by root, root is member of the lpadmin group.

If i change the permissions to 777, the web interface says "not found" and the log tells me that the permissions are unseure...

I can reproduce it everytime.

You need to tell us how you can reproduce it because from my testing I can't find any issue.

fightforlife commented 8 years ago
  1. Fresh installation of simplesNas image: http://simplenas.com/download/banana-pi-m1 (which is wheezy with omv, used it long time before without problems.)
  2. apt-get upgrade, verifiying everything works.
  3. installing cups pugin, activating plugin. Always the same permission error on Cups Webend

Which permissions should this file have? /usr/lib/cups/cgi-bin/admin.cgi

All other plugins and functions are working just fine....

It at least works on an amd64 system. From what I gather that sounds more like a cups package problem than a bug in the plugin. The correct permissions are that the file is owned by root and has 755 permissions.

@ryecoaaron I don't own a Banana Pi so I can't reproduce it, maybe you've got any ideas?

I would agree that this is a package issue with the BPi. I don't own one either but we have a lot of issues with the BPi. Pretty sure this doesn't happen on the RPi so I rule out the plugin and arm architectures as the issue.

Thank you very much for your answers, i tried to reach the developer of the bpi image, but so far no answer, I will probably try a standard debian wheezy image without omv. If CUPS works there I know its an image problem. If it doesnt it is a cups package problem. I will let you know, thanks again.

There's nothing we can do if we can't reproduce it. I'm not much for pure guessing.
