Hi

As we have one application in which it creates files with user& group as ownership "nobody", due to that there are issues in overwriting the same file.

Can anybody suggest how we can prevent this ownership assignment as "nobody"


Thanks

So, the application is running as user nobody. It creates files. Those files then are owned by nobody. nobody's primary group is nobody. so the group ownership is nobody. This also means that you have a directory that is writable by nobody (or, likely 777 which is writable by anybody).

The contradiction here is that you have an application you don't trust and run as nobody, yet you have a directory that you have set up to allow anyone to write to. You need to lock all of that down a bit.

Typically, if an application is running like that you want to know about it, and user nobody kind of hides it. Create a user for that application. Then if that application needs a log file or something to write to, create the log file for it and set the permissions so it can write to it. Don't have it world writable.
