Hi,
First of all, NET-SNMP's snmpwalk and the SNMP
GETBULK operation are two totally different things.
GETRBULK is similar to GETNEXT. Thus if you provide
an instance OID (ends with .0) you will not get
the instance but its successor (if available).
snmpwalk works very differently and it is not worth the
time trying to compare it with GETBULK.
Best regards,
Frank

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
