Summary: 5.4 snmptrap/trapsess send notifications to port 161
Initial Comment:
snmptrap from net-snmp 5.4 and 5.5.dev defaults to sending traps on port 161.
Example:
% snmptrap -d -v2c -c public localhost 1024 1.2.3.4
Sending 64 bytes to UDP: [127.0.0.1]:161

This patch is applied to the 5.4.x and main development branches, so it is
apart of all 5.4.1 prereleases and anything later than that on the 5.4
branch.
It is also part of the trunk.

Thanks for the patch! It has been applied to the 5.4.x
code branch and the main development tree, and will
appear in future releases of the Net-SNMP package.

Found out that the trapsess directive also contained the bug.
Thanks to Ricardo Marin Vinuesa for the test case.
Updated the patch to handle that case as well.
Description of changes from the previous version:
agent/agent_trap.c
Use snmp_add instead of snmp_open in order to get the right application
type.
File Added: patch

The patch depends on patch #1653670, if that one isn't added as well this
fix won't correct the problem properly.
Description of the changes:
apps/snmptrap.c:
Do not depend on NETSNMP_DS_LIB_DEFAULT_PORT for setting of the port that
should be used, use snmp_add and netsnmp_transport_open_client to open a
transport using the right application instead.
apps/snmptrapd.c:
Do not assume that every transport uses :162 for trap reception, instead
use the unmodified user input as argument to
netsnmp_transport_open_server.
snmplib/snmpUDPDomain.c:
snmplib/snmpUDPIPv6Domain.c:
Change the priority of targets so that NETSNMP_DS_LIB_DEFAULT_PORT is
better than the default target from the application lookup.
snmplib/snmp_api.c:
Remove the setting of NETSNMP_DS_LIB_DEFAULT_PORT in _init_snmp as it
isn't needed any more and, given the priority change, would render the
default target from application lookup useless.

I use the command
patch -p0 < /tmp/patch
to apply the patch
Further I have found that the patch contained a minor error so I have
uploaded a new version (the old one had an unrelated change to
agent/agent_trap.c that removed an unused variable).
Oh yes, tanders, this bug doesn't affect trapsess configs since that
doesn't use the DS_LIB_DEFAULT_PORT mechanism to select the port.

For completeness, the problem is believed to also affect "trapsess"
configs and the like.

I have noticed that the a and b patch together didn't produce the right
result as I had managed to misapply one of them. The attached patch is a
combintion of them that also solves the misapplied chunk.
File Added: patch

The problem with patch a is that snmptrap -d -v2c -c public
--defTarget='snmptrap udp :55555' localhost 1024 1.2.3.4 still sends on
port 162 and not on 55555 as expected.
This is due to problem a) and the following patch solves it but is not in
and by itself enough to solve the original problem - both patches are
needed for that!
File Added: b

This patch is enough to solve the symptom and problem b) but problem a)
still remains.

The problems here is that
a) snmp_open assumes that the transport domain should be "snmp" while
"snmptrap"
is correct for trap sending
b) NETSNMP_DS_LIB_DEFAULT_PORT is given lower priority than the result
from the
domain lookup
