Site update: Let’s encrypt!

Let’s Encrypt for Windows 10

Step by step:
1. VirtualBox install ubuntu linux
2. Install certbot
3. 利用 certbot 產生 cert
我是用 “http 驗證” , 要上傳驗證檔案到 web site 到指定目錄並修改 web.config.
certbot -d "" --manual --preferred-challenges http certonly
4. cert pem 轉為 pfx (要輸入 password)
openssl pkcs12 -export -out /tmp/certificate.pfx -inkey privkey.pem -in cert.pem -certfile chain.pem
5. 在 IIS 設定 pfx
6. Done!

How To: Ubiquiti NanoBeam as WIFI access point

1. 設定你的 Notebook / PC 的 network card 為固定 IP address (我選了 )
2. 連接你的 Notebook / PC 的 network card 到 NanoBeam.
3. Web login , user name / password: ubnt
4. Web :Ubiquiti Logo – airMax – Disable.
5. Web :Wireless : Wireless Mode : Access Point, DFS -Disable , Change SSID , Wireless Security – WPA2-AES,WPA Authentication – PSK. (有些手機只可用 20M bandwidth, 否則看到 SSID 但連不上)

1. 設定你的 Notebook / PC 的 network card 為固定 IP address (我選了 )


windows command prompt :(找出 network card name)
Windows IP Configuration
Ethernet adapter Local Area Connection :

(network card name = Local Area Connection)

windows command prompt :(設定你的network card 為固定 IP address)
netsh interface ip set address name=”Local Area Connection” static

windows command prompt :(之後復元 setting)
netsh interface ip set address name=”Local Area Connection” dhcp

4. Web :Ubiquiti Logo – airMax – Disable.



可坐高鐵+巴士, 台北車站<->高鐵桃園站 , 高鐵桃園站巴士<->機場.
全程1小時, 勝在不用怕塞車/天氣不好.

1.可在台北車站地面東三門, 背向高鐵售票處有電梯直達月台, 同時有工作人員人工驗票.
要準備2小時以上的時間到機場, 不然會有上不了機的危險.

1. 很近火車站的Hotel 是首選
2. 台北火車站置物箱, 可隨時利用, 但放大型行李有困難.
3. 台北車站行李託運中心, 開放時間08:00 ~20:00, 1件 $70/天, 人工作業.
台北車站地面東三門 / 捷運台北車站站出口M2(較近, 有電梯)
