Cuando tenemos un bloqueo por IPtables debido a muchos intentos de logins err\u00f3neos, podemos remover el bloqueo ingresando por ssh a nuestro servidor, con el siguiente comando veremos las reglas, incluidas las IP bloqueadas y el servicio asociado, en este ejemplo la IP 192.168.70.15 bloque\u00f3 intentos de FTP<\/p>\n
iptables -L -n<\/p>\n
ahora identificamos la l\u00ednea del bloqueo, que ser\u00eda as\u00ed:<\/p>\n
iptables -D fail2ban-pureftpd -s 192.168.70.15 -j DROP<\/p>\n
y luego verificamos si se elimin\u00f3 con el mismo comando de listado<\/p>\n
iptables -L -n<\/p>\n
M\u00e1s que un gran tutorial, es una ayuda memoria.<\/p>\n
