DISPLAY環境變量格式如下host:NumA.NumB，host指Xserver所在的主機主機名或者ip地址，圖形將顯示在這一機器上，可以是啟動了圖形界面的Linux/Unix機器，也可以是安裝了Exceed 、X-Deep/32等Windows平台運行的Xserver的Windows機器。
如果Host為空白，則表示Xserver運行於本機，並且圖形程序（Xclient）使用unix socket方式連接到Xserver，而不是TCP方式。使用unix socket方式連接時則表示連接的unix socket的路徑，如果為0，則表示連接到/tmp/.X11-unix/X0
如果Host非為空白, 使用TCP方式連接時，NumA為連接的端口減去6000的值，如果NumA為0，則表示連接到6000端口；
NumA + 6000 = tcp port #
NumB則幾乎總是0。
---------------------------- 進階 ------------------------------------------------------------------------
如果使用su username或者su - username切換到別的用戶,並且使用命令
export DISPLAY=:0.0
設置DISPLAY環境變量,運行圖形程序(如xclock)時會收到如下錯誤:
Xlib: connection to ":0.0"refused by server
Xlib: No protocol specified
Error: Can't open display: :0.0
這是因為Xserver默認情況下不允許別的用戶的圖形程序的圖形顯示在當前屏幕上.如果需要別的用戶的圖形顯示在當前屏幕上,則應以當前登陸的用戶,也就是切換身份前的用戶執行如下命令
xhost +
這個命令將允許別的用戶啟動的圖形程序將圖形顯示在當前屏幕上.
在2台Linux機器之間,如果設置服務器端配置文件/etc/ssh/sshd_config中包含：
X11Forwarding no
客戶端配置文件/etc/ssh/ssh_config包含：
ForwardX11 yes
則從客戶端ssh到服務器端后會自動設置DISPLAY環境變量,允許在服務器端執行的圖形程序將圖形顯示在客戶端上.在服務器上查看環境變量顯示如下(這個結果不同的時候並不相同)
DISPLAY=localhost:10.0
在客戶機上用netstat -lnp可以看到有程序監聽了6010端口
tcp 0 0 127.0.0.1:6010 0.0.0.0:* LISTEN 4827/1
如果希望允許遠程機器上的圖形程序將圖形顯示在本地機器的Xserver上,除了要設置遠端機器的DISPLAY環境變量以外,還需要設置本地機器的Xserver監聽相應的TCP端口.而現在的Linux系統出於安全的考慮,默認情況下不再監聽TCP端口.可通過修改/etc/X11/xinit/xserverrc文件,將
exec /usr/bin/X11/X -dpi 100 -nolistentcp
修改為
exec /usr/bin/ X11/X -dpi 100
允許在直接使用startx啟動圖形時啟動對TCP端口的監聽.
修改/etc/kde3/kdm/kdmrc,將
ServerArgsLocal=-nolisten tcp
修改為
ServerArgsLocal=
允許kdm作為顯示管理器時,啟動會話時監聽相應的TCP端口.
修改/etc/gdm/gdm.conf,在[Security]一節增加
DisallowTCP=false
或者在登陸窗口選擇"Options" -> "Configure Login Manager..."的Security頁面,取消"DenyTCP connections to Xserver",允許gdm作為顯示管理器時,啟動會話時監聽相應的TCP端口.
--------------------------------------------------------------------------------------------------------
xhost
xhost是用來控制X server訪問權限的。
通常當你從hostA登陸到hostB上運行hostB上的應用程序時，
做為應用程序來說，hostA是client,但是作為圖形來說，
是在hostA上顯示的，需要使用hostA的Xserver,所以hostA是
server.因此在登陸到hostB前，需要在hostA上運行xhost +
來使其它用戶能夠訪問hostA的Xserver.
xhost +是使所有用戶都能訪問Xserver.
xhost + ip使ip上的用戶能夠訪問Xserver.
xhost + nis:user@domain使domain上的nis用戶user能夠訪問
xhost + inet:user@domain使domain上的inet用戶能夠訪

Debian Buster --- net-tools will be deprecated in favor of iproute2
Here is a summary of the net-tools commands, together with their iproute2 equivalent:
| legacy net-tools commands | iproute2 replacement commands |
|---|---|
| arp | ip n (ip neighbor) |
| ifconfig | ip a (ip addr), ip link, ip -s (ip -stats) |
| iptunnel | ip tunnel |
| nameif | ip link |
| netstat | ss, ip route (for netstat -r), ip -s link (for netstat -i), ip maddr (for netstat -g) |
| route | ip r (ip route) |

LENOVO T410 with Debian Buster and XFCE
1. modify /etc/apt/sources.list : add contrib and non-free
2. install intel wifi driver : firmware-iwlwifi
3. Install nvidia driver : install/run nvidia-detect, install nvidia-legacy-340xx-driver
4. Whenever I lock my screen, it goes full black and does not respond either to moving the cursor or pressing keys from the keyboard.
2. install intel wifi driver : firmware-iwlwifi
3. Install nvidia driver : install/run nvidia-detect, install nvidia-legacy-340xx-driver
4. Whenever I lock my screen, it goes full black and does not respond either to moving the cursor or pressing keys from the keyboard.
After searching for a while, I found the solution in the Arch Wiki.
The solution is pretty simple. Just create a text file named 20-intel.conf in the /etc/X11/xorg.conf.d/ directory path (you may have to create directory xorg.conf.d if it does not exist) and paste the following in it:
Section "Device"
Identifier "Nvidia Card"
Driver "nvidia"
VendorName "NVIDIA Corporation"
BoardName "NVS 3100M"
EndSection
Now save the file and reboot your Debian Xfce system.
Screen black problem after locking the screen in Xfce should be solved by now.
5. How to enable my keyboard's volume keys in XFCE?
- Right click a panel -> Panel submenu -> Add New Items...
- Add an instance of PulseAudio Plugin
- Right click the icon that just appeared in your panel and click "Properties". Make sure "Enable keyboard shortcuts for volume control" is enabled.
You may have to install the PulseAudio Plugin first. In Debian and Debian-based distributions, the package is called xfce4-pulseaudio-plugin.

LENOVO T410
After installing my Lenovo T410 to Windows 10, Windows 10 can not find the driver for the PCI Serial Port.
VEN_8086&DEV_3B67&SUBSYS_216217AA&REV_06\3&b1bfb68&0&B3
It need "Intel Management Engine Interface 6.2 and Serial Over LAN (SOL) Driver".

GImageX --- 修改 windows PE 檔 xxx.wim
感覺蠻好用的
Youtube 教學
官網
使用案例
wimlib：一個開源的類似imagex的處理wim神器，（由於imagex最新版識別不了wimboot和esd鏡像，早已經被微軟拋棄）沒有Dism的各種限制支持ESD直接導出為wimboot鏡像或常規壓縮的鏡像。
類似的軟件, 還有 wimtool, 但還是推薦使用 GImageX

購買 2吋 SPI LCD 176*220 驅動=iLi9225 全彩65K +SPI(TF型 SD卡)+SPI FLASH
目前的認知:
1. 此版的 VCC 工作電壓為 3.3V, 不可施加 5V 電源, 否則有燒毀之虞
2. MCU (Arduino/nano) 3.3V 驅動能力通常不足, 需要額外單獨供應 3.3V 電源
3. 除 VCC 外的接腳是否可接受 Arduino (nano) 5V 位準, 尚未測試. 但應可與 Raspberry Pi (3.3V) 直接連接使用
有很多兼容 3.3V/5V 的類似產品可供選擇 (此次買錯了?...但賣家服務真的很好) ===============================================
PCB上的 SD(TF卡)(支援格式:FAT32 最大容量16GB ???)
此螢幕適用於 電壓=3.3V 的MCU 來驅動 2.5V 或 5V 都不適合 螢幕驅動IC是使用 ILI9225 驅動
若遇到5V的MCU, 例如: NANO開發板, 其3.3V驅動能力不足, 需額外供應 3.3V 電源
實驗記錄:
實際使用 : NANO開發板 上的 3.3V 驅動能力不足電壓會低於 3.1V
實際使用 :下載器 CP2102 模組內建 的3.3V 可以提供 足夠的驅動能力(100mA) OK電壓能維持 3.29V
實際使用 :WIFI模組 ESP32 內建1117-3.3 的3.3V 可以提供 足夠的驅動能力(100mA) OK電壓能維持 3.20V
另外:
用DCDC 供應 3.3V 外掛電源的時後 若 NANO開發板 要與 PC 聯接 (其傳輸線是MINI USB ) 插入後 5V腳位的電壓 會拉高到 3.65V 左右 (這個電壓 LCD 還能工作 電流消耗=250mA) 若過 4.5V LCD 就無法顯示 (螢幕會全白) 不過 通常這裡電壓會小於 4.5V (因為MINI USB傳輸線內阻很大 壓降很大)(實測約 3.6V左右)
(若有影響NANO與PC之間資料傳輸 可於資料下載時 先將LCD的外掛電源DCDC 輸出電壓=3.3V 與 NANO分開)
外掛DCDC=3.3V當總電源 將LCD與NANO的VCC 都用3.3V
=============================================================
右邊腳位:
1=VCC:電源3.3V輸入連到(MCU)(STM32)Arduino板的+5VDC或+3.3VDC引腳上 並將原本MCU+5V改成3.3V 系統

8=SDA :(DIN或MOSI)(主機輸出從機輸入)是SPI主機輸出從機輸入引腳用於將數據從MCU發送到TFT
9=A0 :(D/C或DC或RS) 是TFT SPI數據或命令的選腳
10=RST :(或RESET或RES) 是TFT重置腳LOW= 重置
11=CS :TFT_CS 是TFT 選擇腳
============================================================
左邊腳位: (單獨使用 左邊SPI時 需供應3.3V 電源 電源來自 右邊腳的 1=VCC :3.3V 系統 2~3=GND :GND引腳)
1=SD_CS :是選TF 記憶體
2=MOSI :(DIN或SDA)(主出從入)是SPI主機輸出從機輸入引腳，用於將數據從MCU發送到SD卡
3=MISO :(DO或SDO)(主入從出)是SPI主機輸入從機輸出引腳，用於將數據從SD卡發送到MCU
4=SCL :(SCK或SCLK或CLK)=(串行時脈)是SPI時脈輸入引腳
5=F_CS :(SPI_FLASH的選擇或 FLASH_CS)是選擇 FLASH記憶體
實驗記事:
若 MCU 資源夠 或有2個 SPI 介面以上 (或是 有2顆 MCU 分別使用 不同的 SPI介面) 時 可以將 左 右的 信號 分開使用(此PCB 左邊跟右邊的 SPI信號線 是獨立拉出來應用的) 您買 這塊SPI 模組 可以 說是 物超所值 買到賺到
若 MCU 資源不夠 只1個 SPI 介面的時候 時 可以將
左邊的 : 2=MOSI 跟 右邊的: 8=SDA 相並聯
(是SPI主機輸出從機輸入引腳 用於 將數據從MCU發送到指定的 從機)
左邊的 : 4=SCL 跟 右邊的: 7=CLK 相並聯
(是SPI同步主機產生的數據傳輸的時鐘脈衝 是SPI時脈輸入引腳)
可以省下 MCU 2隻SPI的 IO 腳 (也就是 1顆MCU控制 3個 SPI介面模組)
=============================================================
原本預留 SPI FLASH : 使用者 可以自行購買 記憶體來 擴充(IC 自己焊)
目前出貨 都會幫您焊好 16MB的S PI FLASH (空記憶體) (可以當字庫也可以 自行應用)
1=CS :(LOW有效)(強制上拉10K歐姆到VCC)
2=MOSI :(數據資料IO)(強制上拉10K歐姆到VCC)
3=WP :(防寫保護) (LOW有效) (已拉到VCC = 強制可以寫)
4=GND :(共地)
5=MISO :(數據資料IO)(強制上拉10K歐姆到VCC)
6=SCL :(CLK SPI 串列時脈)(跟SD TF卡 共用時脈 2者之間 串聯電阻500歐姆)
7=HOLD :(鎖定) (LOW有效) (已拉到VCC = 強制不鎖定)
8=VCC :(共用VCC=3.3V)

Difference between NetBIOS and SMB
source : Difference between NetBIOS and SMB
1. Are both services necessary? If not, are there any benefits over running a single service?
Depending on your operating system and environment, both services are not necessary.
SMB (Server Message Block)
Server Message Block, the modern dialect of which is known as Common Internet File System, operates as an application-layer network protocol mainly used for providing shared access to files, printers, serial ports, and miscellaneous communications between nodes on a network. ...The Server Message Block protocol can run on top of the Session (and lower) network layers in several ways:
- directly over TCP, port 445
- via the NetBIOS API, which in turn can run on several transports:
- on UDP ports 137, 138 & TCP ports 137, 139 – see NetBIOS over TCP/IP
- on several legacy protocols such as NBF (incorrectly referred to as NetBEUI).
On Windows, SMB can run directly over TCP/IP without the need for NetBIOS over TCP/IP. This will use, as you point out, port
445.
Generally speaking, on other systems, you'll find services and applications using port
139. This, basically speaking, means that SMB is running with NetBIOS over TCP/IP, where, stack-wise, SMB is on top of NetBIOS if you are to imagine it with the OSI model.
Here's a visualization from Richard Sharpe, from samba.org.
Here's a slightly tweaked version to illustrate how you can imagine this on a Windows-based system.
1.a If they are both necessary, are there any benefits?
The only "benefit" -- it's not really a benefit, as much as a requirement -- is that with SMB over NBT (NetBIOS over TCP/IP), you'll actually be able to communicate with a greater deal of implementations of SMB.
2. What information/service does netbios-ssn and microsoft-dsprovide?
*My quick guess is that while
netbios-ssn simply provides the NetBIOS API, including NBT (NetBIOS over TCP/IP) via port 139. On the other hand, microsoft-ds provides the direct hostingof SMB via port 445.*With Windows 2000 Microsoft felt that this can be improved. They added the port 445 for the same service. On port 445 SMB runs directly over TCP. The only difference is that the client skips the NetBIOS session (saves one round trip) then negotiates, authenticates, mounts etc.Check the properties of your network card. Somewhere in the Advanced IP Settings is a checkbox "Enable NetBIOS over TCP". Activate it and your computer uses port 139. Deactivate the option and the system wants to use 445....
- Port 139:
SMB -> NetBIOS -> TCP- Port 445:
SMB -> .... -> TCP
3. What is the relationship between SMB and NetBIOS; are they seperate, does one rely upon the other?
SMB does rely on NetBIOS for communication with devices that do not support direct hosting of SMB over TCP/IP.
NetBIOS is completely independent from SMB. It is an API that SMB, and other technologies can use, so NetBIOS has no dependency to SMB.
NetBIOS (Network Basic System)
... It provides services related to the session layer of the OSI model allowing applications on separate computers to communicate over a local area network. As strictly an API, NetBIOS is not a networking protocol. ...... In modern networks, NetBIOS normally runs over TCP/IP via the NetBIOS over TCP/IP (NBT) protocol. This results in each computer in the network having both an IP address and a NetBIOS name corresponding to a (possibly different) host name. ...
As you can see, the relationship would be
Application -> SMB -> NetBIOS -> (TCP/IP, others).
