fam.conf - The File Alteration Monitor (FAM) configuration file

In addition to its command line options, famd's behavior can also be controlled through its configuration file. By default, this is /etc/fam.conf. The -c command line option can be used to specify an alternate file.

Configuration lines are in the format option=value. Lines beginning with # or ! are ignored. famd recognizes the following options:

insecure_compatibility

If set to true, this disables authentication and reduces access security as described under SECURITY below. This is false by default. Setting this option to true is the same as using the -C command line option.

untrusted_user

This is the user name or UID of the user account which famd will use for unauthenticated clients. If a file can't be stated by this user, famd will not tell unauthenticated clients about the file's existence. If an untrusted user is not given in the configuration file, famd will write an error message to the system log and terminate.

local_only

If set to true, famd will ignore requests from remote famds. This is false by default. Setting this option to true is the same as using the -L command line option. This option is ignored if famd is started by inetd.

idle_timeout

This is the time in seconds that famd will wait before exiting after its last client disconnects. The default is 5 seconds. This option is overridden by the -T command line option.

nfs_polling_interval

This is the interval in seconds between polling files over an NFS filesystem. The default is 6 seconds. This option is overridden by the -t command line option.

xtab_verification

If set to true, famd will check the list of exported filesystems when remote requests are received to verify that the requests fall on filesystems which are exported to the requesting hosts. This is true by default. If this option is set to false, famd will service remote requests without attempting to perform the verification. If the local_only configuration option or -L command line option is used, xtab_verification has no effect.

detect_readonly_filesystems

If set to true, famd will try to detect read-only filesystems. Such filesystems are assumed to never change. This is false by default. Setting this option to true is the same as using the -r command line option.
