Install FAM by running the following commands:
Note: You will get warnings about make install being unable to merge entries in /etc/rpc. These can be ignored, along with any IMON or inetd.conf warnings, as we will be configuring these files after installation.
patch -Np1 -i ../fam-2.6.10-dnotify.patch && libtoolize --force && aclocal && automake --add-missing && autoconf && ./configure --prefix=/usr --sysconfdir=/etc && make && make install |
patch -Np1 -i ../fam-dnotify.patch: This patch causes FAM to use the Linux kernel dnotify mechanism to inform the calling process of file modifications, rather than polling the file system for modifications.
libtoolize --force aclocal automake --add-missing autoconf |
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/bin/fam 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"
