OpenBSD 3.1 and ucd-snmp on sparc64

[Thorsten Steentjes <tst_(_at_)_guug_(_dot_)_de>]

Hello,

I'm trying to configure ucd-snmp-4.2.3 on my sparc64 running OpenBSD
3.1.
It seems that the snmpd is not able to resolve the IP address of the
host that sends the snmp query via UDP.
Here's what I see so far:

sun# tcpdump -n -i gem0 udp dst port 161
tcpdump: listening on gem0
17:59:59.618064 192.168.0.1.3278 > 192.168.0.12.161:  C=public
GetNextRequest(26) .1.3.6.1.2.1.1

So the OS on sun (192.168.0.12) know the IP address of the host that
sends the UDP packets (192.168.0.1)

But snmpd doesn't see the sending host, cause:

sun# /usr/local/sbin/snmpd -a -V -L
Connection from 0.0.0.0
Received SNMP packet(s) from 0.0.0.0
  GETNEXT message
      -- system
          >> system.sysDescr.0 = OpenBSD sun 3.1 GENERIC#0 sparc64

Everything works fine when snmpd listens on a TCP port and I do the
query via TCP. But that's not what I want. The same configuration works
with FreeBSD.

Any ideas?

Thanks
Thorsten
