Edit the new configuration file to suit your network and system needs.

Boot Script

[Note]

Note

The NAS server cannot run simultaneously with other sound servers, such as MAS or JACK.

Install the /etc/rc.d/init.d/nas init script included in the blfs-bootscripts-20060910 package. 

make install-nas

The init script uses a default prefix of /usr/X11R6. If you've installed the X Window System into any other prefix, execute the following command, replacing <PREFIX> with the installation prefix of the X Window System. 

sed -i 's@/usr/X11R6@<PREFIX>@' /etc/rc.d/init.d/nas

The init script uses a default parameter to allow access to all hosts on the network. Review the nasd man page for other available parameters if you need to modify the script.
