AFPD(8)

Name
afpd — 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.

Signals
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.
