Hi,
I'm facing a problem when executing a walk operation to get a single
value. I'm using snmp4j 2.0.2. I've tried with the main provided in jar
but I've the same result.
What am I doing wrong ?
Here what I receive when I use the snmpwalk :
lobj:$ snmpwalk -v 2c -c public 10.67.219.49 1.3.6.1.2.1.1.3.0
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (363840427) 42 days,
2:40:04.27
If I execute the same operation with SnmpRequest.java, I receive this
:
lobj@:$ java -cp ../lib/snmp4j-2.0.2.jar:../lib/log4j-1.2.16.jar
org.snmp4j.tools.console.SnmpRequest -Ow -c public -v 2c 10.67.219.49
