[16:39:41] openhabian@openhab:~$

This happens even after a ‘fix permissions’ in openhabian-config

here are the ls -la


[16:51:55] openhabian@openhab:~$ ls -la /usr/share/firemotd/data
total 12
drwxr-xr-x 2 root root 4096 Oct 10 05:58 .
drwxr-xr-x 6 root root 4096 Oct  8 23:29 ..

[16:52:16] openhabian@openhab:~$ ls -la /usr/share/firemotd     
total 24
drwxr-xr-x   6 root root 4096 Oct  8 23:29 .

drwxr-xr-x   2 root root 4096 Oct  9 11:03 themes
[16:52:35] openhabian@openhab:~$

which I see is root:root. Shouldn’t it be openhabian:openhabian? or openhabian:openhab? or root:openhabian? or some other iteration?

if so, should this correction be in the ‘fix permissions’? (not a criticism, just a question)

Thanks

This is a FireaMotD issue. For to a recent change to that third party software, the openhabian user needs permission to write to /usr/share/firemotd/data. I’m not sure why they do that as it’s pretty unusual. But they do, do you either need to chown that folder so openhabian owns it or chmod it so all users can work to it.

FireMotD is a third party software so openhab-cli isn’t going to addresses this.

ok. thought something like that. I’d have probably put the changeable data in /var/lib/firemotd or something like that. But whatever.

Here’s the fix I put in, for whatever it’s worth:

(EDITED on 2019 Oct 15 to only affect the /usr/share/firemotd/data subdirectory, since that’s the only subdirectory that is actually written to.)

[16:52:35] openhabian@openhab:~$ sudo -s
[17:34:46] root@openhab:/home/openhabian# find /usr/share/firemotd/data -type d -exec setfacl -m d:g::rwx,g::rwx,d:g:openhabian:rwx,g:openhabian:rwx {} \;
[17:36:11] root@openhab:/home/openhabian# find /usr/share/firemotd/data -type f -exec setfacl -m g::rw,g:openhabian:rw {} \;
[17:37:05] root@openhab:/home/openhabian# find /usr/share/firemotd/data -type d -exec chmod g+s {} \;
[17:37:41] root@openhab:/home/openhabian#

cheers
