server端：
安裝
/usr/ports/net/rsync
/usr/local/etc/rsyncd.conf
[My_Pictures]
path = /home/www/pictures
comment = public pictures
auth users = notexist
secrets file = /usr/local/etc/rsyncd.secrets
read only = no
incoming chmod = Dugo=rwx,Fu=rw,Fgo=r
P.S. chmod只能用這方式敘述的樣子，D、F分別代表資料夾和檔案，u、g、o依序是持有者、持有群組跟其他，rwx就是剩下的權限敘述
Client端Task：
“C:\Program Files\cwRsync\bin\rsync.exe” -vr –progress –password-file=rsync.txt “/cygdrive/c/Documents and Settings/NotExist/My Documents/My Pictures/” notexist@hq.tdcpf.org::My_Pictures
