Is the message `unable to bind trap socket' or `unable to bind
multicast trap socket'?

The first message would be serious as someone else is already using
port 162. The second message can be ignored in most cases. Straps does
not only open UDP port 162 to receive traps, it also tries to open UDP
port 162 on the multicast group 234.0.0.1. You will very likely get a
warning while opening the multicast trap socket if you are not
connected to a multicast network device. Ignore it.
