Hi All,
Thanks you very much in advance for your inputs.
I am getting the very peculiar issue, while using the net-snmp for testing
V3.
V3 authentication is failing during sending Traps as well as with SnmpWalk.
But the same issue is not observed with various other tools like
ireasoning,, mgsoft ...
Below are the details of the configuration and error messages I have
observed.
Please do the needful.
PS: Even sometimes with the same setup, V3 operations are getting success.
Server is used by me alone.
*Configuration:*
*snmptrapd.conf:*
createUser -e 0x80000F1500 testv3stuff MD5 test1234 DES test1234
authUser log,execute,net testv3stuff
authCommunity log,execute,net public
*Command For Starting the TrapDaemon: (NET-SNMP Version: 5.7.2)*
snmpwalk -v 3 -l authPriv -u testv3stuff -a MD5 -A test1234 -x DES -X
test1234 167.254.169.78:1611 .1.3.6
*Console Logs:*
