APF (Advanced Policy Firewall) este un sistem de firewall สำหรับ ลินเวกซ์, bazat pe iptables (netfilter).
Atunci cand APF-ul a blocat accesul la server mai multor IP-uri, exista doua variante ca sa puteti scoate aceste limitari. Prima varianta ar fi comanda directa din consola (sau prin ssh) prin care puteti scoate pe rand IP-urile blocate. Puteti face acest lucru prin comanda:
apf -u 117.41.182.209ที่ไหน “117.41.182.209” este IP-ul care o fost blocat de APF. Mesajul rezultat in urma comenzii va fi:
apf(7931): {trust} removed 117.41.182.209 from trust systemIn cazul in care este un numar mare de IP-uri blocate, metoda de mai sus ne-ar lua ceva timp pana le-am elimina pe toate. Pentru a sterge toate IP-urile, va trebui sa curatam fisierul in care sunt stocate IP-urile blocate. Adica fisierul deny_hosts.rules จาก /etc/apf -
Pentru a realiza acest lucru, stergem fisierul deny_host.rules si restartam serviciul apf. Comenzile de mai jos:
rm -rf /etc/apf/deny_host.rules
/etc/init.d/apf restart
Acum au fost sterse toate IP-urile blocate de APF si serviciul repornit. In cazul in care doriti recuperarea listei de IP-uri blocate de APF, deschideti fisierul deny_hosts.rules.back-
