[SNMP4J] Problem with SNMP V3 MD5/DES

Tue Dec 7 01:36:26 CET 2004

Hi Frank,

Thanks for the promptly reply.

The command I gave is like "java SnmpRequest -x DES -X password -D DEBUG -p GETNEXT  -v 3 -a MD5 -A password -u jackie 192.168.151.55 1.3.6.1.2.1". Is it possible to have 2 instances of SNMPs in this case? (I run it in command line and one at once.)

I downladed it 2 weeks ago and the "change.txt" contains this line "[2004-10-13] Version 1.0.3a:". Therefore, I think I am using the latest version.

Thanks

--Jackie

Hi Jackie,

Are you using the latest SNMP4J version?
 From the log it seems that the time synchronization fails. This can be caused by two managers (Snmp instances) using the same engine ID.

Best regards,
Frank
