    This article describes how Apple Files Services starts under Mac OS X Server.

DISCUSSION

    The startup process for the AppleFileServer begins with AdminWebServer. AdminWebServer is started at boot by inetd if the server is configured for AppleFileServer. The configuration is checked and AdminWebServer started with the script '/etc/startup/1600_AppleShare' which checks for the configuration in hostconfig as well as NetInfo.

    cat /etc/startup/1600_AppleShare
    #!/bin/sh

    . /etc/rc.common

    CheckForNetwork

    if [ "${NETWORKUP}" = "-NO-" ]; then exit; fi

    ##
    # Start the AFP Server
    ##
    if [ "${AFPSERVER:=-NO-}" = "-YES-" ]; then
    ConsoleMessage "Starting AppleShare server"

    echo "Starting the AdminWebServer server"
    /usr/sbin/AdminWebServerctl start
    fi

    If AppleFileServer's NetInfo property is set to start AppleFileServer at startup, the AdminWebServer server starts a single process of AppleFileServer (the "parent process") which does not serve files. That single parent process generates the second process (the "child process") which actually performs the file serving.

    ps ax |grep AppleF
    632 ?  I     0:00 AppleFileServer /tmp/afpserver_PIPE
    639 ?  S     0:00 AppleFileServer /tmp/afpserver_PIPE

    ps al 632
    F  UID   PID  PPID CP PRI BASE VSIZE RSIZE WCHAN STAT TT  TIME COMMAND
    4    0   632     1  0  10   10 6.19M  368K     0  I   ?   0:00
    AppleFileServer /tmp/afpserver_PIPE

    ps al 639
    F  UID   PID  PPID CP PRI BASE VSIZE RSIZE WCHAN STAT TT  TIME COMMAND
    4    0   639   632  0  10   10 38.6M 2.05M     0  S   ?   0:00
    AppleFileServer /tmp/afpserver_PIPE

    To administer the AppleFileServer, the AdminWebServer server is used again. Connecting to the server on port 311 (http://servername:311) connects to the AdminWebServer server (using a FastCGI). The settings added by AdminWebServer, along with other configuration settings for the AppleFileServer, are stored in the NetInfo database.
