I wonder what they think they're attacking?
In addition to a self written gopher server I also have a QOTD server accepting requests via TCP and UDP. I never mentioned it as I just put it out there to really see what would happen. I will occasionally see a request go by, but over the past two weeks, some people have really been hitting it hard via UDP:

There doesn't see to be much I can find about this,
other than a potential link to XBox Live,
but that doesn't
seem right.
It's hard to say.
So to see what might be happening,
I modified the QOTD program to record anything it receives via UDP.
That way,
I should be able to figure out if 38.21.240.153
is trying to attack something,
or if it really just wants an up-to-date quotes file.
