Hallo @all

ich habe auf meinem Server mit SYN_RECV attacken zu kämpfen.
Laut netstat -tapen schlagen diese auf auf tcp6 auf.
Nur bin ich der Meinung, das ich IPv6 nicht aktiv habe.
Es sind auch andere tcp6 Verbindungen offen.
Z.B.

Code:

tcp6       0      0 :::22                   :::*                    LISTEN
tcp6       0      0 :::443                  :::*                    LISTEN
tcp6       0      0 :::443                  :::*                    LISTEN
tcp6       0      0 :::111                  :::*                    LISTEN
tcp6       0      0 :::80                   :::*                    LISTEN
tcp6       0      0 :::80                   :::*                    LISTEN


Wie geht das? Was könnte ich übersehen haben?
Wie kann ich IPv6 endgültig sperren?


Code:

ip addr show | grep inet6


Zeigt nichts an.
