使用這台nas想要使用的功能及遇到的情況

1。怎麼使用 ssh 功能

在DSM管理介面上的控制台 > 終端機，

就可以使用ssh登入操作，root密碼等於admin


2。怎麼在這台架dns server

DSM 版本為 3.1，它內鍵已有bind這個套件了，路徑在 /usr/syno/named/，裡面有個 S05dns.sh 程式，

將它放到/usr/syno/etc/rc.d，可以讓bind開機時執行，或者可以先 ./S05dns.sh start 打開bind dns 服務功能

我要啟動 ntop時，/etc/init.d/ntop start 出現

                                                           [失敗]

解決方式是: 編輯/etc/init.d/ntop

在 start() 的地方

將
    daemon $prog -d -L @/etc/ntop.conf
改為
    daemon $prog @/etc/ntop.conf

也就是去掉 -d -L

我有一個主機，主機板是 p5ql-e，它的網卡是 Atheros 1000M Ethernet Network Driver

當我在使用drbl+clonezilla，於pxe開進clonezilla後，出現如下圖問題

有可能是這個網路卡不被drbl 的kernel支援(非os的kernel)

我拿 atheros 的 linux driver去編譯

os 的 kernel 現在為 2.6.18-238.12.1.el5

也在/lib/modules/2.6.18-238.12.1.el5/kernel/drivers/net/atl1e/看到我剛編譯的模組 (alt1e.ko)

Server 端建置

環境 

CentOS 5.6 x64

OpenVPN 2.2.0

預設的yum庫沒有openvpn

所以我要用 dar rpm

rpm -ivh http://apt.sw.be/redhat/el5/en/x86_64/rpmforge/RPMS//rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm

安裝 OpenVPN

yum install openvpn

OpenVPN本身提供一個小型的KEY的管理工具，它是建構在openssl底下的，套件裝好後，在/usr/share/doc/openvpnXXX目錄下就會有easy-rsa目錄

環境:
。CentOS 5.6 x64
。Samba 3.x

摸擬:
。兩個使用者(cross,cross2)，可以讀寫自已的家目錄
。cross  能讀寫 cross2 的家目錄
。cross2 只能讀 cross 的家目錄
。多一個 /data 目錄，可以給cross2讀而已，cross可以讀寫

先新增這兩個user，並把他們放到同一個群組裡去

groupadd ssorc
useradd -G ssorc cross -s /sbin/nologin
useradd -G ssorc cross2 -s /sbin/nologin

新增帳號後的權限狀態

如果你跟我一樣安裝了 virtualbox 4.0.8的話，會發現子機無法使用usb

我上網找了許久，完全沒有解答 (就算我加裝了 extension pack也不行)

不過在新版的 4.0.10 已修正了這個問題，我也更新了，且真的可以使用usb了，可喜可賀!!

官網發佈的訊息如下
