Apple Filing Protocol daemon

Synopsis

afpd [-d] [-F configfile]

afpd [-v | -V | -h]

Description

afpd provides an Apple Filing Protocol (AFP) interface to the Unix file system. It is normally started at boot time by netatalk(8).

afp.conf is the configuration file used by afpd to determine the behavior and configuration of a file server.

Options

-d: Do not disassociate daemon from terminal.
-v: Print version information and exit.
-V: Print verbose information and exit.
-h: Print help and exit.
-F configfile: Specifies the configuration file to use.

To shut down a user's afpd process it is recommended that SIGKILL (-9) NOT be used, except as a last resort, as this may leave the CNID database in an inconsistent state. The safe way to terminate an afpd is to send it a SIGTERM (-15) signal and wait for it to die on its own.

SIGTERM and SIGUSR1 signals that are sent to the parent afpd process are propagated to the children, so all processes will be affected.

SIGTERM: Clean exit. Propagates from parent to children.
SIGQUIT: Sending this to the parent afpd will cause it to exit, but leaving all children running! This can be used to implement an AFP service without downtime.
SIGHUP: Sending a SIGHUP to afpd will cause it to reload its configuration files.
SIGINT: Sending a SIGINT to a child afpd enables max_debug logging for this process. The log is sent to the file afpd.PID.XXXXXX in the system tmp directory. Sending another SIGINT will revert to the original log settings.
SIGUSR1: The afpd process will send the message "The server is going down for maintenance." to the client and shut itself down in 5 minutes. New connections are not allowed. If this is sent to a child afpd, the other children are not affected. However, the main process will still exit, disabling all new connections.
SIGUSR2: The afpd process will look in the message directory configured at build time for a file named message.pid. For each one found, a the contents will be sent as a message to the associated AFP client. The file is removed after the message is sent. This should only be sent to a child afpd.
