Andy, wonderful to hear from you. And thanks for your method of getting snmp
traps into Hobbit. It is a bit of a feather in my cap that I can do so. My
boss is anxious to get rid of our highly priced NetCool monitoring package,
but we needed to be able to monitor traps, at least from our F5 devices.

Yes, I looked again at the code and realized that I was mistaken, and have
already apologized to Henrik for having the temerity to suggest that there
might be a bug in his code.

Yes, but that was sometime ago. Maybe before I made some other corrections
to get things working. I'm tempted to just down a server to cause a trap.

Yes, I've seen that. In order to get things to work, I've had to make
/etc/host file entries and make sure that the sending devices are configured
to send their traps via certain interfaces so that the IP address will
correspond to the host file address.
