Emby Permissions on Ubuntu Server 20.04


Recommended Posts

Posted (edited)

Hi Guys 

I would some help cause I m struggling to get over this problem with Linux Permissions.

I recently Installed Ubuntu server 20.04 LTS, before Emby server was running on a Linux Mint without problems but due various reasons I moved to Ubuntu Serv. now.

The main issue is when I try to add the library on Emby server, going to the path /media/serv01/DB01/VIDEOTECA , I get stuck, Emby don't show anythings after /media/serv01/ and it back to the  main screen where you need to add the folder, it does the same with the network /path ,when actually that dir is shared on LAN too. if I do manually It say "could not find the path"

However I think its a permissions problem so I have followed couple guide to give emby user the read permission to read that folder but seems not work anyway.
I DON'T want to give write and Execute permissions to Emby user but only read would be enough for me and him :) I believe my mistake its somewhere about difference from folder and files SubDir ecc ecc.... you know linux ask you an Hight level of knowlodges and I dont have all of them, that why I,m asking help to someone who know more about permissions in linux and can push me on the rigth way to give read permissions to emby   
 
that what I ve done without any good result

 
serv01@nas-01:~$ sudo chmod 770 -R /media/serv01/DB01/VIDEOTECA/
serv01@nas-01:~$ sudo chown -R serv01:emby /media/serv01/DB01/VIDEOTECA



serv01@nas-01:~$ ls -l /media/serv01/DB01/VIDEOTECA/
total 44
drwxrwx---  3 serv01 emby  4096 May 15 11:28  Cartoons
drwxrwx---  2 serv01 emby  4096 Jun  5 16:13  Documentari
drwxrwx---  3 serv01 emby  4096 Jul  3 03:21  IPTV
drwxrwx---  5 serv01 emby 20480 Jun 15 13:36  Movies
drwxrwx--- 13 serv01 emby  4096 May 24 11:21 'Series TV'
drwxrwx---  2 serv01 emby  4096 May 24 11:21 'Ultimi Inseriti'
drwxrwx---  2 serv01 emby  4096 Jun  1 14:02 'Video Bambini'
serv01@nas-01:~$ 

if I m not get it wrong 770 shoud give rwx to the owner (7) rwx to the group (7) serv01 and no permission to the others (0) then If I m not wrong (d)rwxrwx d= directory 

leaving my confusion above ololo, I would to get a command which give to emby all reads permissions from /media/Serv01 (where emby seem to get stuck) to the files on subs directory so /media/serv01/DB01/VIDEOTECA/Movies/file.mkv


I have also just to try give the above commands from /media/serv01 

which is not a good idea give that to a not admin user 

so 


  serv01@nas-01:~$ sudo chmod 770 -R /media/serv01
serv01@nas-01:~$ sudo chown -R serv01:emby /media/serv01


serv01@nas-01:~$ ls -l /media/serv01

but it did't work anyway 

please give a slap to wake me up from this :) 




***also have add emby user to serv01 group or at least I ve tried 

that the output 



/etc/group:adm:x:4:syslog,serv01
/etc/group:cdrom:x:24:serv01
/etc/group:sudo:x:27:serv01
/etc/group:dip:x:30:serv01
/etc/group:plugdev:x:46:serv01
/etc/group:lxd:x:116:serv01
/etc/group:serv01:x:1000:emby
serv01@nas-01:~$

you need to add the emby user to the emby group if you want to set it up this way.

I tried what you said, hopefully... added Emby on emby group, and in case added emby user on serv01 group aswell 

that what I ve done and it is .... but still not works 

once I click from emby managing panel the folder /media/serv01/     doesn't show any contents

Generally, when you modify groups for a user in Linux, you need to logout and back in, or, reboot if it's more convenient. Yes, there are other ways, but, this is simplest. So, if you modified emby user, all processes with emby need to be stopped and logged out.

I didn't know that, however rebooting not help my problem :/

Try it as the emby user to see if you can spot the problem.

sudo su -s /bin/bash emby

Run "id" to verify session is emby now.

Navigate down your media path to test access. You have an ACL on /media/serv01 which might be part of the problem.

yeah you are right it cannot access to the folders after /media/serv01/

Try one at a time to see how far emby can go.

cd /media

cd serv01

The emby user might not have read permissions on /media/serv01. There's an ACL on that directory and it might be blocking emby.

See above. There are no signs of ACLs in the rest of your listings. Probably best to remove the ACL and let standard permissions take over.

setfacl -b /media/serv01
