RE: IPv6 and snmptrapd not processing traps

Once I changed the args to "udp:162 udp6:162" it works fine. The difference is the space rather than a comma. Also, ::1/loopback is wrong.

Subject: [E] RE: IPv6 and snmptrapd not processing traps


I've been working with Kevin on this issue and I have more detailed information.



I've been testing IPv6 traps and I am confused about how the trap is being received and processed, compared to IPv4 traps (I suspect there is a bug).

Here is an ipv4 trap that was spooled to /var/spool/snmptt/

1460708637
localhost.localdomain
UDP: [127.0.0.1]:41908->[127.0.0.1]:162
DISMAN-EVENT-MIB::sysUpTimeInstance 0:0:38:59.38
SNMPv2-MIB::snmpTrapOID.0 NET-SNMP-EXAMPLES-MIB::netSnmpExampleHeartbeatNotification
NET-SNMP-EXAMPLES-MIB::netSnmpExampleHeartbeatRate 123456

Here is an ipv6 trap that was spooled to /var/spool/snmptt/

1460708648
UDP/IPv6: [::1]:50618
UDP/IPv6: [::1]:50618
DISMAN-EVENT-MIB::sysUpTimeInstance 0:0:39:10.94
SNMPv2-MIB::snmpTrapOID.0 NET-SNMP-EXAMPLES-MIB::netSnmpExampleHeartbeatNotification
NET-SNMP-EXAMPLES-MIB::netSnmpExampleHeartbeatRate 123456


The confusion lies with the 2nd and 3rd line of the trap.

On an IPv4 trap, the 2nd line is:

localhost.localdomain

This is the host that sent the trap (for testing purposes I sent it to myself).
I sent it to 127.0.0.1, and it was translated to localhost.localdomain.
This is the normal behaviour.

On an IPv6 trap, the 2nd line is:

UDP/IPv6: [::1]:50618

This is my first problem.
I believe it should be:
::1
and if dns resolution was working, then it would have resolved to something like localhost6.localdomain6.


On an IPv4 trap, the 3rd line is:

UDP: [127.0.0.1]:41908->[127.0.0.1]:162

It shows me it was received via UDP, what address/port sent it and the destination address/port.
This is the normal behaviour.

On an IPv6 trap, the 3rd line is:

UDP/IPv6: [::1]:50618

This is my second problem. I beleive it should be:

UDP/IPv6: [::1]:50618->[::1]:162


I believe this is an issue with net-snmp due to observation of the (debug) logging.

I start snmptrapd with the following command:

snmptrapd -DALL -f -Lo udp:162 udp6:162 -c /etc/snmp/snmptrapd.conf

In another ssh session I execute the following commands:

snmptrap -v 2c -c public 127.0.0.1 '' NET-SNMP-EXAMPLES-MIB::netSnmpExampleHeartbeatNotification netSnmpExampleHeartbeatRate i 123456

snmptrap -v 2c -c public ::1 '' NET-SNMP-EXAMPLES-MIB::netSnmpExampleHeartbeatNotification netSnmpExampleHeartbeatRate i 123456

Which generates lots of logging information on the screen. I think these lines of out show what's going on:

IPv4

IPv6

I edited the file snmpIPv6BaseDomain.c and found lines 114-116 (which are part of netsnmp_udp6_fmtaddr)

snprintf(tmp, sizeof(tmp), "%s: [%s%s]:%hu", prefix,
                 inet_ntop(AF_INET6, (void *) &(to->sin6_addr), addr,
                           INET6_ADDRSTRLEN), scope_id, ntohs(to->sin6_port));

If I change them to:

snprintf(tmp, sizeof(tmp), "%s%s",
                 inet_ntop(AF_INET6, (void *) &(to->sin6_addr), addr,
                           INET6_ADDRSTRLEN), scope_id);

Then the second line in the trap changes to:

::1

But it also changes the third line to the same thing, whereas it should be as I described above.


At this point I know I've reached as far as my skills can let me progress.

I do believe there is a bug in the output of lines 2 and 3 of IPv6 traps, if I am mistaken please explain why.
As far as I would assume, the output of an IPv6 trap should follow the same format as an IPv4 trap.


Here are the specific testing details.
