Hi,
I made a program (reading_room.tcl), with Sqlite running on Debian 9,
to control the books of a reading room.
I implemented an authentication system for common users and
administrator users in the reading_room.tcl program.
Now I want that any user logged in the Linux be able to run the
program reading_room.tcl, which will access the database (books.db)
But I want to protect the file books.db so that only the the program
reading_room.tcl can access the books.db file (to read or write). But
that no user could delete or write to the file books.db (only the
program reading_room.tcl)
Please, how can I configure the system to do that?
How to define the permissions?
Thanks,
Markos
If you have read, and used, this:
https://www.sqlite.org/src/doc/trunk/ext/userauth/user-auth.txt than you
should know the answer ;)
Otherwise set access permissions on the database (use: 'man chmod'
and/or 'man chown', to find out how to do that under Debian 9)
If a user has no right to modify the db, and tries to do an update, an
error is returned from sqlite:
sqlite> insert into User values(42);
Error: attempt to write a readonly database
