Solaris 建立 Anonymous FTP Server

　　加入以下资料在 /etc/passwd ，这个例子选择 /export/ftp 作为 anonymous ftp area。设定为不能看见 Shell 的內容 /nosuchshell。

　　ftp:x:30000:30000:Anonymous FTP:/export/ftp:/nosuchshell

　　加入以下资料在 /etc/shadow

　　ftp:NP:6445::::::

　　以下shell script用來设定anonymous ftp area

　　把以下內容放入 /etc/ftpanonymous

　　#!/bin/sh

　　# script to setup anonymous ftp area

　　#

　　# verify you are root

　　/usr/bin/id | grep -w ’uid=0’ >/dev/null 2>&1
