Re: Czasowe reguły iptables

To naprawdę dobra wiadomość :D.
Możesz z resztą ubić wszystkie połączenia, bo prawdopodobnie wiszą w regułach zawierających RELATED,ESTABLISHED, dlatego nie znikają od razu.


Trzeba by tylko wszystkie reguły dotyczące kontroli stanu pakietu objąć takimi samymi warunkami, jak INPUT i OUTPUT, czyli jest z tym trochę dodatkowej zabawy.

Przy czym nie ma różnicy, czy w skrypcie Crona, czy regułami w FW, bo sytuacja z nawiązanymi i kontynuowanymi połączeniami w obu przypadkach będzie wyglądała identycznie.

W demokracji każdy naród ma taką władzę, na jaką zasługuje ;)

Re: Czasowe reguły iptables

Ja nieco przerobiłem swój skrypt iptables i ostatecznie to wygląda tak:

Kod:

    iptables -t filter -A INPUT -m conntrack --ctstate RELATED,ESTABLISHED,NEW -m mark --mark 5 -j time-p2p
    iptables -t filter -A INPUT -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT
        ...

    iptables -t filter -A OUTPUT -m conntrack --ctstate ESTABLISHED,RELATE,NEW -m cgroup --cgroup 5 -j time-p2p
    iptables -t filter -A OUTPUT -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT
        ...
