Introduction<\/h1>\n

Connect\u00e9 \u00e0 un wifi publique dont le firewall bloque de nombreux ports sortants, je me suis demand\u00e9 comment savoir si chacun d’eux est ouvert et ferm\u00e9.<\/p>\n

Le script<\/h1>\n

Voici le script que j’ai trouv\u00e9 et adapt\u00e9. Il fonctionne sur Mac et Linux.<\/p>\n

On lance le Terminal et on cr\u00e9e le fichier testports.sh<\/code> sur le Bureau :<\/p>\n

$ cd ~\/Desktop\/<\/pre>\n
$ nano testports.sh<\/pre>\n
On copies ces lignes dans le fichier :<\/p>\n
#!\/bin\/bash\r\n\r\nfor x in `seq 1 65535`; do\r\n\r\n    echo -ne \"$x \"\r\n    curl \"http:\/\/portquiz.net:$x\" \\\r\n      --connect-timeout 2 \\\r\n      --max-time 1 \\\r\n      -o \/dev\/null \\\r\n      -q >\/dev\/null 2>&1 \\\r\n        && echo 'open' \\\r\n        || echo 'closed'\r\n\r\ndone | tee ports.lst<\/pre>\n
On enregistre, on quitte et on rend le script ex\u00e9cutable<\/a> :<\/p>\n
$ chmod u+x testports.sh<\/pre>\n
On lance le script :<\/p>\n
$ .\/testports.sh<\/pre>\n
Tous les ports s’affichent un par un.
\nLorsque l’op\u00e9ration est termin\u00e9e, un fichier r\u00e9capitulatif est cr\u00e9\u00e9 sur le bureau : ports.lst<\/code>.<\/p>\n
Notes<\/h1>\n
Le script interroge le site http:\/\/portquiz.net<\/code> qui r\u00e9pond sur tous les ports.<\/p>\n
\"TestPorts-01\"<\/a><\/p>\n
Comme indiqu\u00e9 sur le site, les ports 21<\/code>, 22<\/code>, 25<\/code>, 445<\/code>, … ne r\u00e9pondent pas et sont interpr\u00e9t\u00e9s comme ferm\u00e9s par le script.<\/p>\n
