LCOM::Lab2 - Configuration

9. Configuring your Program

Your program invokes functions that are privileged. Thus, before you can run it, you need to add a file named lab2 to the /etc/system.conf.d/ directory to grant your program the necessary permissions.

Unless you use privileged functions that are not really necessary, the following entry is enough:

service lab2
{
        system
                DEVIO
                IRQCTL
                ;
        ipc
                SYSTEM
                rs
                vm
                pm
                vfs
                ;
        io
                40:4      # i8254 ports
                61        # port for speaker control
                ;               
        irq
                0         # TIMER 0 IRQ 
                ;       
        uid     0               
                ;
};

You can find this file in file lab2/conf/lab2 of the archive with Lab2 directory tree.

IMP. Remember that you must be root to write to /etc/system.conf.d/
