sunnyone / synouidmod Goto Github PK

Hi,

Thanks for this tool !
Purchased a DS920+ to replace a very old ReadyNAS.

I've managed to compile and run your tool on DS920+, after backing up the synosdk folder.
I've managed to change the UID of my user to keep it the same as various other systems to be able to use NFS without the need for UID mappers etc.

However, changing the UID to less than 1000 makes it disappear from the Synology web UI.
For the moment i have therefore changed it back.

Do you know if there is a way to patch also the web UI to be able to show and configure users even if you changed them to something below 1000 ?

Or do you know of another workaround ?

Cheers.

Hi @sunnyone ,

I needed to change a UID temporarily after updating to 6.2.4 to be able to change something in the UI, but the synouidmod tool no longer seems to work in 6.2.4.

romain@nas:[/opt/builds/synouidmod/build]$ sudo ./synouidmod romain 1026 100
Database opened successfully
User 'ROMAIN' has been found: username=romain, uid=500, gid=100
Modifying 'romain' to uid=1026, gid=100
Update failed

It worked fine back in december on DSM 6.2.3.

I rebuilt the tool on 6.2.4 thinking it might have to be rebuilt on top of the updated version of the dependencies, but didn't work as well. I'm not familiar with the synology SDK unfortunately. Do you know what the issue could be ?

Thanks,
Romain.

Hello @sunnyone,

I've been able to successfully compile synouidmod (Target: DSM 6.2, Plattform apollolake).

However, synouidmod doesn't seem to work.

No matter which user I pass as an argument, the errror is always User XYZ is not found

command

void@nas:/volume1/test$ sudo ./synouidmod plex
User 'plex' is not found.

/etc/shadow

plex:$XXXXXXXX/:17690:0:99999:7:::

Am I doing something wrong or is this a bug?

synouidmod seems not work with DSM newest 6.23

The Error message is:
-ash: ./synouidmod: cannot execute binary file: Exec format error

Please take a look.

Hello again @sunnyone,

I found another problem: The changes made by synouidmod are not persistent.
If you reboot DSM, all changes are lost.

admin@vdsm:/volume1/workspace$ sudo ./synouidmod test 10123 10234
Database opened successfully
User 'test' has been found: username=test, uid=1026, gid=100
Modifying 'youtrack' to uid=10123, gid=10234
Update successfull

# reboot ...

admin@vdsm:/volume1/workspace$ sudo ./synouidmod test
Database opened successfully
User 'TEST1' has been found: username=test, uid=1026, gid=100
No modifications applied to database

Is there something we can do or is synouidmod working as intended?
In the latter case my solution would be to create a script and execute it after every start of DSM

update

id -u USERNAME (which reads /etc/passwd) doesn't work too. Take a look at this please:

admin@vdsm:/volume1/workspace# ./synouidmod test 9000 100
Database opened successfully
User 'TEST' has been found: username=test, uid=1026, gid=100
Modifying 'test' to uid=9000, gid=100
Update successfull

admin@vdsm:/volume1/workspace# ./synouidmod test
Database opened successfully
User 'TEST' has been found: username=test, uid=9000, gid=100
No modifications applied to database

adim@vdsm:/volume1/workspace# id -u test
1026
