有時候人不在電腦前，遇到一定需要用電腦處理的事情或許可以透過遠端桌面解決。但如果這些需要常駐的主機，電腦或者 NAS 因為停電或其他因素關機了，卻無法馬上返回家中開機，這時候如果能透過網路開機就顯得頗為便利。其實這種網路開機功能一般稱之為 WOL (Wake On LAN) 網路喚醒功能，藉由網路(一般為有線網路) 傳送一個特定格式的 WOL Magic 封包至支援的主機板及網卡，便可以遠端地開啟已經關機的主機或NAS了。
如果想要透過 WOL 來開機，你必須具備以下的條件
– 支援 WOL 的主機板 (現今的主機板幾乎都支援)
– 搭配支援 WOL 的網卡 (判斷方法即是網卡有沒有多一條 WOL 的供電線)
Coolstar has released a new beta version of Electra jailbreak toolkit for iOS 11 – iOS 11.1.2. The author also release the source code of the jailbreak toolkit on Github. I would like to try to find out how the toolkit work by building it on my own. So I wrote this guide for people (who may be a developer) can follow instructions and build Electra toolkit successfully.
The most important of all, before you start to read this guide, make sure you have the ability to handle the problem you meet. You are fully doing this at your own risk, I’m not responsible for any damage caused.
If you don’t know what this article is doing, you can download the released ipa on the author website resign by tools such as iResign and install it to your iPhone without building it youself.
