connexion TELNET EN PHP vers CISCO
Posté : 09 août 2012, 10:58
bonjour je bosse actuelement sur un projet universitaire qui est de recuperer un chaine de carractère d'une requette TELNET en PHP sur un cisco Catalyst 2960 24 ports et Catalyst 5500 series.
voici mon programme.
PHPCiscoTelnet.php
et la page de test
test.php
alors voila pour les IOS j'ai bien un affichage de la requete "show mac-address-table"
mais quand je passe sur un CATOS comme le Catalyst 5500 avec la requete "show cam dynamic"
la je n'ai rien qui s'affiche
pouvez vous m'aider????
merci d'avance

alors voila pour les IOS j'ai bien un affichage de la requete "show mac-address-table"
mais quand je passe sur un CATOS comme le Catalyst 5500 avec la requete "show cam dynamic"
la je n'ai rien qui s'affiche
pouvez vous m'aider????
