As far as I understand, source code is not distributed with Sothether, and you cannot re-compile or port to other machine.
Ntop (N2N) is Open Source, and you can re-compile.
我只試過最簡單的 bridge 方法。
1. client side 要一部機裝 bridge 版本。做bridge的機要手動set static IP。設定好server資料就得。
2. client side router 要 disable DHCP。
做齊以上兩件事所有其它駁去client side router 的設備都會拎到 server side IP。(做bridge的機除外,所以我買多部RPi做bridge)
