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.
