Bevor ich hier nen ticket eröffne kurze information zu "linux.sh" des Gw6-Clients unter freetz
Änderungen:
Änderungen:
- Der Parameter für entfernen von IFs / Adressen wurde angepasst
- Das Script gibt nun bei startfehlern von "radvd" Konfigurationsparameter aus um eventuell den radvd-Daemon selber zu Konfigurieren)
- Es wird nun überprüft ob die datei "radvd-conf" (von gw6c) existiert, bevor er gestartet wird -> Config-infos werden dann ausgegeben...
- Gestript (Kommentare entfernt) sparte 1 KB! XD
