Hi,
I am trying to setup traps for snmpv3. I am cross-compiling for a system
running arm. I build with the following options
./configure --prefix=/usr --without-check --host=arm-none-linux-gnueabi
--with-mib-modules="mibII if-mib disman/event notification"
--enable-mini-agent --with-perl-modules=no --disable-embedded-perl
--without-rpm --with-default-snmp-version=3 --disable-snmpv1
--disable-snmpv2c
--with-sys-contact=root@localhost--with-sys-location=unknown
--with-logfile=/var/log/snmpd.log
--with-persistent-directory=/var/net-snmp --disable-manuals
--disable-scripts
Any comments regarding my configuration options would be very much
appreciated, my goal is to have a lightweight snmpd but with enough of the
options set to cover the most basic stuff. Anyway after building net-snmp I
have installed it on the target and I am currently trying to make the
coldStart trap to work but without any success.
My snmptrapd.conf
createUser -e 0x80001f88808c18d3f7b0000 trapuser MD5 administrator DES
rootpasswd
snmpTrapdAddr udp:127.0.0.1:162
authuser log trapuser
and my /etc/snmp/snmpd.conf
syslocation "Sitting on the Dock of the Bay"
syscontact m...@example.org
agentAddress udp:161
trapsess -v 3 -e 0x80001f88808c18d3f7b0000 -u trapuser -a MD5 -A
administrator -l authPriv -x DES -X rootpasswd udp:127.0.0.1:162
#authtrapenable 1
iquerySecName defaultuser
#linkUpDownNotifications yes
and my /var/net-snmp/snmpd.conf
createUser defaultuser MD5 "administrator" DES rootpasswd
and my /usr/share/snmpd.conf
rouser defaultuser
*I am using the same configuration files except from the engineID's on the
host and there the trap coldStart work.*
*

I have built net-snmp on the host with the following options
./configure --with-logfile=/home/userA/Workspace/snmp/var/log/snmpd.log
--with-persistent-directory=/home/userAi/Workspace/snmp/var/net-snmp
--prefix=/home/userAi/Workspace/snmp/usr --without-check
--with-mib-modules="mibII if-mib disman/event notification"
--enable-mini-agent --with-perl-modules=no --disable-embedded-perl
--without-rpm --with-default-snmp-version=3 --disable-snmpv1
--disable-snmpv2c
--with-sys-contact=root@localhost--with-sys-location=unknown
--disable-manuals --disable-scripts
When starting snmpd on the target on the target system I get the following
output
$> snmpd -Dtrap -f -Le
registered debug token trap, 1
Log handling defined - disabling stderr
trap: freeing trap sessions
trap: send_trap 0 0 SNMPv2-SMI::enterprises.8072.3.2.10
NET-SNMP version 5.7.2
Received TERM or STOP signal... shutting down...
trap: send_trap 6 2 SNMPv2-SMI::enterprises.8072.4
trap: freeing trap sessions
$>
If I then start the snmpd on the host system with the same options I get
the following output
$> sudo snmpd -Dtrap -f -Le -c /home/userA/Workspace/snmp/conf/snmpd.conf
registered debug token trap, 1
Log handling defined - disabling stderr
trap: freeing trap sessions
trap: adding callback trap sink (0x929570)
trapsess: adding to trap table
trap: send_trap 0 0 SNMPv2-SMI::enterprises.8072.3.2.10
trap: sending trap type=167, version=3
NET-SNMP version 5.7.2
^CReceived TERM or STOP signal... shutting down...
trap: send_trap 6 2 SNMPv2-SMI::enterprises.8072.4
trap: sending trap type=167, version=3
trap: freeing trap sessions
$>
I thought I would get the same output since both are built with the same
options? One thing that I notice is that on the host where the traps work I
get the output
trap: adding callback trap sink (0x929570)
which I don't get on the target system. Also if I run the command
snmptrap -e 0x80001f88808c18d3f7b0000 -v 3 -u trapuser -a MD5
-A administrator -l authNoPriv localhost 42 coldStart.0
it works. Any thoughts on how I can debug this problem would be very much
appreciated.
