Now that I think about it, I think I was seeing something like this back in
March, before my systems got hacked. I just thought it was bad information,
or chewed up headers or something like that. As a matter of fact, looking
through my logs reveals a very similar pattern around the 22nd of April
(that's as far back as my logs go).
As a tangent to that, I'm seeing quite a few entries in my portsentry logs
about attempts to access port 111, which is the sunrpc port, which I think
is tied to portmapper. <dumbquestion> What is portmapper, and why would I
want it running? </dumbquestion>

I've seen the following in my log files. I'm wondering if it's an attempt at
a
buffer overflow. Has anyone else seen this?
