Hi,
i am trying to receive snmp traps generated by relayd and send via snmpd to
a host running net-snmp snmptrapd.
there i only get the error
Cannot find TrapOID in TRAP2 PDU
config:
# ------------OpenBSD 4.5 snmpd.conf: -------------
listen_addr="127.0.0.1"
# Restrict daemon to listen on localhost only
listen on $listen_addr
# Specify a number of trap receivers
trap receiver linuxsnmpserver
#trap receiver localhost
trap community secret
# Adjust the local system information
system contact "foo"
system description "Powered by OpenBSD"
system location "just here"
system services 74
# ------------ ends -------------
# --------------- net-snmp snmptrapd.conf: --------------
authCommunity log,execute secret
traphandle default /usr/sbin/snmptrapfmthdlr
# ------------ ends -------------
i tried with snmptrapd versions
NET-SNMP version 5.4.2.1 (on OpenBSD)
NET-SNMP version 5.4.1 (on Linux)
both with the same result:
snmptrapd[1360]: truncating signed value to 32 bits (1)
snmptrapd[1360]: Cannot find TrapOID in TRAP2 PDU
when started with debugging output
the result of a relayd host down event looks like this:
# snmptrapd -f -Le -d 127.0.0.1
NET-SNMP version 5.4.2.1

The snmptrapd can receive traps generated with the Net-SNMP snmptrap
programme:
snmptrap -v 2c -c secret localhost "" OPENBSD-BASE-MIB::localTest \
SNMPv2-MIB::sysLocation.0 s "Just here"
