Netatalk 4.5.0
Filesystem Change Events
Netatalk includes a filesystem change event (FCE) mechanism that allows afpd processes to notify interested listeners about certain filesystem events via UDP network datagrams.
This feature is disabled by default. To enable it, set the fce listener option in afp.conf to the hostname or IP address of the host that should listen for FCE events.
Netatalk distributes a simple FCE listener application called fce_listen. It prints any UDP datagrams received from the AFP server. Its source code also serves as documentation for the format of the UDP packets.
FCE v1
The supported FCE v1 events are:
-
file modification (fmod)
-
file deletion (fdel)
-
directory deletion (ddel)
-
file creation (fcre)
-
directory creation (dcre)
FCE v2
FCE v2 events provide additional context such as the user who performed the action. FCE v2 also adds the following events:
-
file moving (fmov)
-
directory moving (dmov)
-
user login (login)
-
user logout (logout)
