les 2 OS sont Ubuntu...
Je ne comprends tjs pas...
en ligne de commande via : snmpget -t 3 -r 0 -v 1 -c nomCommunaute ip 1.3.6.1.4.1.9.9.156.1.2.1.1.5.1
ça fonctionne dans les 2 OS!!!
Je ne comprends tjs pas pq le programme me lance un segmentation fault avant de rentrer dans le main...
Si quelqu'un a une idée?
Appeler 1 fonction dans main c
