Uno de los inconvenientes que encontraba de Firestarter era que te obligaba a indicar por que interfaz\/dispositivo de red ten\u00edamos acceso a Internet para configurar correctamente el Firewall. En mi port\u00e1til esto es un inconveniente dado que dispongo (como la gran mayor\u00eda) de tarjeta ethernet y tarjeta wireless, por tanto no siempre utilizo la misma para conectarme en las diferentes redes que trabajo.<\/p>\n

Esta situaci\u00f3n provocaba que tuviese que acordarme de cambiar manualmente la configuraci\u00f3n de Firestarter. Sin embargo, ahora he encontrado una soluci\u00f3n en el foro de Ubuntu<\/a>. Se trata de crear un script que cambiar\u00e1 la configuraci\u00f3n de Firestarter de forma autom\u00e1tica cada vez que Network Manager se conecte a una red.<\/p>\n

Creamos el fichero ‘\/etc\/NetworkManager\/dispatcher.d\/firestarter’ con el siguiente contenido (no es el mismo script que el del foro, lo he mejorado un poco para que cambie tambi\u00e9n valores del gconf):<\/p>\n

\r\n#!\/bin\/sh -e\r\n# Script to dispatch NetworkManager events\r\n#\r\n# Runs firstarter with proper interface name  when NetworkManager fiddles with interfaces.\r\n#\r\n\r\nif [ -z \"$1\" ]; then\r\n    echo \"$0: called with no interface\" 1>&2\r\n    exit 1;\r\nfi\r\n\r\n# put interface name in quotes\r\nIFACE='\"'$1'\"'\r\n# extract currently set-up interface for firestarter from configuration file\r\nCONF_IFACE=`grep ^IF= \/etc\/firestarter\/configuration | sed 's\/IF=\/\/'`\r\n\r\n# Run the right scripts\r\ncase \"$2\" in\r\n    up)\r\n        # set interface in firestarter config file to $IFACE\r\n        # start firestarter\r\n        chmod +w \/etc\/firestarter\/configuration\r\n\r\n        # Internet interface\r\n        sed -i \"s\/^IF=$CONF_IFACE\/IF=$IFACE\/\" \/etc\/firestarter\/configuration\r\n        gconftool-2 --set -t string \/apps\/firestarter\/firewall\/ext_if $1\r\n\r\n        ## Optional\r\n        # Disable NAT (Shared Internet connection)\r\n        #sed -i \"s\/^NAT=\\\"on\\\"\/NAT=\\\"off\\\"\/\" \/etc\/firestarter\/configuration\r\n        #gconftool-2 --set -t boolean \/apps\/firestarter\/firewall\/nat false\r\n        #sed -i \"s\/^DHCP_SERVER=\\\"on\\\"\/DHCP_SERVER=\\\"off\\\"\/\" \/etc\/firestarter\/configuration\r\n        #gconftool-2 --set -t boolean \/apps\/firestarter\/firewall\/dhcp\/enable_server false\r\n\r\n        chmod -w \/etc\/firestarter\/configuration\r\n        firestarter --start\r\n        ;;\r\n    down)\r\n        # just stop firestarter, when interface is shut down\r\n        firestarter --stop\r\n        ;;\r\nesac\r\n<\/pre>\n
Y finalmente le damos permisos de ejecuci\u00f3n:<\/p>\n
\r\nchmod 755 \/etc\/NetworkManager\/dispatcher.d\/firestarter\r\n<\/pre>\n
Network Manager ejecuta todos los scripts del directorio ‘\/etc\/NetworkManager\/dispatcher.d\/’ cuando se conecta a una red y pasa como par\u00e1metros la interfaz o dispositivo de red que utiliza y si se ha conectado o desconectado.<\/p>\n","protected":false},"excerpt":{"rendered":"
