Permissions problem

[jmcgee]

I have PVR1, acting as file server and mythbackend, with internal drive mounted at /mnt/media3
I also have acerrevo acting as mythfrontend. I log onto each as user name mythuser.

MythTv can't delete files, and I'm assuming this is because of permissions.


mythuser@PVR1:/mnt/media3/myth/recordings$ id mythuser
uid=1001(mythuser) gid=125(mythtv) groups=125(mythtv),4(adm),20(dialout),21(fax),24(c drom),25(floppy),26(tape),29(audio),30(dip),44(vid eo),46(plugdev),105(scanner),107(fuse),109(lpadmin ),115(admin),121(netdev),127(sambashare)



mythuser@acerrevo:/mnt/media3$ id mythuser
uid=1001(mythuser) gid=1001(mythuser) groups=1001(mythuser),4(adm),20(dialout),21(fax),2 4(cdrom),25(floppy),26(tape),29(audio),30(dip),44( video),46(plugdev),104(fuse),112(netdev),119(admin ),121(nopasswdlogin),122(sambashare),123(mythtv)

I brute forced the solution earlier with chmod 777, but I want to get it right.

My guess is the GID needs to match, and maybe UID?

So on the client (acerrevo) to try and match the gid to the server, I did


mythuser@acerrevo:/mnt/media3$ groupmod --gid 125 123
groupmod: group '123' does not exist


what am I missing?

Right click on a file and see who the owner is and who can change content. Also try removing a file with sudo using the terminal

sudo rm <file path/file name>

ShadowVegan; Hi !
As an observation, neither of your ends have "sudo" access. For reference, mine:

sysop@1304mini:~$ iduid=1000(sysop) gid=1000(sysop) groups=1000(sysop),4(adm),24(cdrom),27(sudo),29(au dio),30(dip),46(plugdev),108(lpadmin),109(sambasha re)
sysop@1304mini:~$
27(sudo); do you need to add that user to the sudo group ?


just a thought

[steeldriver]

as well as needing to do the groupmod from a 'sudo' account, you will probably need to give the actual target group name (mythtv), rather than its current gid i.e.


sudo groupmod -gid 125 mythtv

e.g.



$ sudo groupadd --system mythtv
$
$ getent group mythtv
mythtv:x:999:
$
$ sudo groupmod -g 127 999
groupmod: group '999' does not exist
$
$ sudo groupmod -g 127 mythtv
$ getent group mythtv
mythtv:x:127:
$


Obviously the gid 125 needs to be available on the acerrevo machine (it wasn't on mine - which is why I used 127 above)
