Wuerth VPN – plattformuebergreifende Tray-App (PyQt6).
|
||||
|
||||
Baut das VPN rootlos auf (openconnect + ocproxy als SOCKS5) und startet einen
|
||||
dedizierten Browser, der per PAC nur die internen Hosts ueber das VPN schickt
|
||||
und alles andere direkt. Start/Stop ueber das Tray-Icon.
|
||||
|
||||
macOS/Linux: lauffaehig. Windows: rootloser ocproxy-Pfad noch zu verifizieren.
|
||||
|
||||
Abhaengigkeiten:
|
||||
pip3 install PyQt6 --break-system-packages
|
||||
openconnect + ocproxy auf dem PATH (macOS: brew install openconnect ocproxy)
