Configuring NAS

Config Files


Configuration Information

Create the NAS configuration file using the following command:

install -v -m644 /etc/nas/ /etc/nas/nasd.conf

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

Boot Script



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.
