Salut à tous,
J’ai un petit problème pour un script que j’essaye d’améliorer. j’ai ajouter des options à mon script via un ‘case’ pour que cela fasse plus propre, mais je me rend compte que l’options du nom de communauté de la commande ‘snmpwalk’ que j’invoque dans mon script est vide.
j’ai par ailleurs remarqué lorsque j’utilise la commande que le nom de communauté est toujours vide (e.g. ps -ax):
/usr/bin/snmpwalk -v 2c -c ip_address .1.3.6.1.4.1.334.72.1.1.2Est-ce lié ?
De plus j’ai beau chercher je ne trouve pas de script bash sur le net qui utiliserai “snmpwalk”, y’a bien la solution d’écrire tout en Perl mais ceci est mon premier gros script et je métrise encore moins le Perl.
Enfin je post à tout hasard si jamais quelqu’un a déjà rencontré le problème.

fiMerci de vos lecture 
p.s.: La variable $CHECK qui pointe vers le programme check_lnmp_Mibs.sh est juste un script qui lance une requête snmpwalk sur l’OIDs Lotus et l’envoi vers un fichier
p.s. 2: Si vous avez des avis ou remarque je suis toutes ouies ^^
