Re: More problem with snmpv3 and traps:

Hi,

Some more information regarding my problems with traps. When running the
following command on the host computor I get som more output

>$./snmpd -Dtrap -Dtrapsess -DsnmpNotifyTable -Dsend_notifications  -f -Le
registered debug token trap, 1
registered debug token trapsess, 1
registered debug token snmpNotifyTable, 1
registered debug token send_notifications, 1
Log handling defined - disabling stderr
snmpNotifyTable: initializing...  snmpNotifyTable: done.
trap: freeing trap sessions
trap: adding callback trap sink (0xd4d630)
trapsess: adding to trap table
snmpNotifyTable: adding data...  snmpNotifyTable: registered an entry
snmpNotifyTable: done.
snmpNotifyTable: storing data...  snmpNotifyTable: done.
trap: send_trap 0 0 SNMPv2-SMI::enterprises.8072.3.2.10
send_notifications: starting: pdu=0xd5ff40, vars=0xd604e0
send_notifications: checking filters...
send_notifications:   no matching profile
trap: sending trap type=167, version=3
send_notifications: sent 1 notifications
NET-SNMP version 5.7.2

When running the same command on the target I get the following output

 $> ./snmpd -Dtrap -Dtrapsess -DsnmpNotifyTable -Dsend_notific
ations  -f -Le
registered debug token trap, 1
registered debug token trapsess, 1
registered debug token snmpNotifyTable, 1
registered debug token send_notifications, 1
Log handling defined - disabling stderr
snmpNotifyTable: initializing...  snmpNotifyTable: done.
trap: freeing trap sessions
snmpNotifyTable: storing data...  snmpNotifyTable: done.
trap: send_trap 0 0 SNMPv2-SMI::enterprises.8072.3.2.10
send_notifications: starting: pdu=0x80788, vars=0xc24b8
send_notifications: sent 0 notifications
NET-SNMP version 5.7.2

clearly on the target the trap is not sent. Any help regarding this are
appreciated. I am using the same config flags when building for the host
and the target and it's the same configuration files.
