NAME

   famd - The File Alteration Monitor (FAM) daemon

SYNOPSIS

   famd [-CdflLv] [-C conffile] [-p prog.vers] [-t period] [-T timeout]

DESCRIPTION

   FAM,  the File Alteration Monitor, is a subsystem that applications can
   use to be notified when specific files or directories are changed.   It
   is intended as a replacement for mechanisms such as poll and select.

   FAM  comes in two parts: famd, the daemon that listens for requests and
   provides notifications, and libfam a library that  client  applications
   can  use  to  communicate with FAM.  For further information on libfam,
   see the fam(3) manual page.

   famd is normally started by an Internet superserver such  as  inetd  or
   xinetd,  but  can  also be started independently.  Only one instance of
   famd can be run at a time.

   famd can be configured by editing  the  famd  configuration  file  (see
   fam.conf(5)  for further details) or by providing the following command
   line options:

OPTIONS

   -c conffile
          Read configuration information from conffile.

   -C     Run  in  backwards  compatibilty   mode.    This   is   disables
          authentication and is not recommended.

   -f     Run in the foreground.

   -v     Enable verbose messages.

   -d     Enable verbose messages and debug messages.

   -l     Disable polling of files on remote NFS servers.

   -L     Only accept connections from local clients.

   -r     Detect read-only filesystems.

   -p prog.vers
          Register  with the portmapper using the specifed RPC program and
          version numbers.

   -P port
          Bind to the specified TCP port instead of choosing at random.

   -t period
          Poll a remove NFS server every period  seconds  to  obtain  file
          updates if the remove server is not running famd.

   -T timeout
          Exit timeout seconds after the last client disconnects.  A value
          of 0 causes famd to run forever.

SECURITY

   famd never opens the files it's monitoring,  and  only  monitors  files
   that the client can stat.

FILES

   /etc/fam.conf
          Default famd configuration file.
