Dnotify patch (Recommended): http://www.linuxfromscratch.org/patches/blfs/5.1/fam-2.7.0-dnotify-1.patch
Install FAM by running the following commands:
patch -Np1 -i ../fam-2.7.0-dnotify-1.patch &&
autoreconf -f -i &&
./configure --prefix=/usr --sysconfdir=/etc &&
make &&
make install
patch -Np1 -i ../fam-2.7.0-dnotify-1.patch: This patch enables FAM to use the Linux kernel dnotify mechanism to inform the calling process of file modifications, rather than polling the file system for modifications.
autoreconf -f -i This command is necessary since the dnotify patch affects the configure.ac and Makefile.am.
Configuring the file alteration monitor.
If you use inetd, add the FAM entry to /etc/inetd.conf with the following command:
echo "sgi_fam/1-2 stream rpc/tcp wait root /usr/sbin/famd fam" >> /etc/inetd.conf
If you use xinetd, add an entry to /etc/xinetd.conf with the following command (be sure the "nogroup" group exists):
cat >> /etc/xinetd.conf << "EOF" # description: FAM - file alteration monitor service sgi_fam { type = RPC UNLISTED socket_type = stream user = root group = nogroup server = /usr/sbin/famd wait = yes protocol = tcp rpc_version = 2 rpc_number = 391002 } EOF
If you do not have any inetd daemon installed and have no wish to install one, you can also start fam during system startup by installing /etc/rc.d/init.d/fam init script included in the blfs-bootscripts-5.1 package.
make install-fam
The FAM package contains the famd executable and libfam libraries.
