Ubuntu Manpage: afpd — Apple Filing Protocol daemon

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 main afpd process are propagated to the children, so all
will be affected.

SIGTERM

Clean exit. Propagates from master to childs.

SIGQUIT

Send this to the master afpd, it will exit leaving all children running! Can be used to implement
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 /tmp/afpd.PID.XXXXXX. 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.
