URL network utils

Petite collection utile pour avoir des infos diverses:

en-têtes serveur
informations du certificat SSL
résolutions DNS
whois, ping, traceroute…

Ça passe par exec() pour utiliser curl, openssl, nslookup, dig, ping, traceroute et whois. Faut juste s'assurer que le système sur lequel tourne le script dispose bien de ces outils.

NB: il n'y a aucune sécurité basique (échappement et contrôle d'entrée, antiflood..) donc à ne pas laisser en accès public.
