安裝nxserver

yum install freenx


使用的key:

/etc/nxserver/client.id_dsa.key

xp - 用指令來改使用者密碼

指令：net user username password

ex:
net user abc 123
此指令會把abc這個使用者的密碼改成123


如果想用net user新增、刪除使者也可以

net user abc /add
新增abc這個使用者

net user abc /del
刪除abc這個使用者

madwifi - error message

在安裝madwifi的時候　如果遇到設定kernelpath的問題

可以去抓kernel-devel的rpm下來安裝　然後再裝madwifi就好了


錯誤訊息：please set KERNELPATH. Stop.

然後安裝rpm：kernel-devel-2.6.25-14.fc9.i686　(以fedora9為例)

iwpriv

Locking to a Specific Mode
To lock the card to a specific mode, use:

iwpriv ath0 mode 11a To lock to 11a only.
iwpriv ath0 mode 11b To lock to 11b only.
iwpriv ath0 mode 11g To lock to 11g only.
iwpriv ath0 mode 0 (default) autoselect mode.


Changing Authentication Mode.

Use:
iwpriv ath0 authmode 1 To use open authentication.
iwpriv ath0 authmode 2 To use shared key authentication.
iwpriv ath0 authmode 3 To use 802.1x authentication.

讓linux使用者在特定時間才能登入

簡單說就是利用crontab和usermod這兩個東西

原理：

定時把某個使用者的shell改成 /sbin/nologin
這樣他就不能登入了

然後在特定時間把shel改成 /bin/bash
這樣就可以正常登入了

---------------------------------------

製作方式：　(好像怪怪的XD)

用 crontab -e 進去編輯

假如我要星期一下午5點開啟帳號　晚上11點關閉
0 17 * * 1 usermod userABC -s /bin/bash
0 23 * * 1 usermod userABC -s /sbin/nologin

這樣應該就可以了　= =+

可是我還沒有實際去做　等做完再說　XD

看起來應該是沒問題啦　科科

Fedora 的 網路連線

在終端機打NetworkManager　右上方的工具列會多一個圖示 (注意大小寫)

按下去之後　就會出現可以連線到哪裡的選項
用來連無線網路很方便　= =+

而且可以直接連到有加密的AP　他會自動叫你輸入密碼
就跟在XP下連無線網路一樣方便　XDD

安裝：
yum install NetworkManager

Fedora 7 - install gcc 3

yum install compat-gcc-34 compat-gcc-34-c++

設定預設閘道

有時候 default gateway 會變成不是你要的那個

打 ip route show 可以查詢

如果要把192.168.0.1設成default gateway　可以打這個指令

route add default gw 192.168.0.1

查詢ftp的登入紀錄

不知道為什麼　vsftp的log一直沒東西　囧

後來轉去查詢系統紀錄

發現log裡的messages裡面有一些紀錄

打less messages｜grep ftp就可以看跟ftp相關的紀錄

記得把｜改回半形的字　上面那個指令是全形的｜
