Interesting looking at the logs I see my computer
go out and request mail from a pop 3 account and it SHOWS my password? is it
supposed to do that??? This tool could be dangerous in the wrong
hands..

I also notice now that I am scanning again that
48% of my traffic is ARP traffic coming from my router does that not seem a
little high??
Why would it need to ARP so many times isn't
there an ARP cache in the router to allow it to not request so many times?
Right now just in a 2 min scan there was over 2100 requests?
Thanks

That will obviously be much better. However, I still would
hesitate to allow my provider complete control over my router. I have
quite a few "Tweaked" routers, we run wccp, cef and a few other things that
I need to know are running correctly. Just my .02, Not being a smart
ass or anything.

Well that is true if I had a Cisco router I
would be able to do that but megapath gave me this cheesy Siemens router
and they did not install any kind of firewall software installed so I cant
make any rules in it or I would have done this long ago. The attack
stopped so I am not to worried anymore.. but you are right with the new
managed router from AT&T I will request certain IP schemes to be
blocked..

It is not really your providers problem. If you are an ISP,
you need to know how to manage your router. That is not meant to
be a slam or anything, but if you have traffic coming into your network,
you need to know where it is from and how to manage
it.

I don't have ping.exe in there?? I also
tried ICMP I am calling my provider to block both their class C blocks
from ever getting to me. My partner went to go pay them a visit OHH
man I feel sorry for them HE IS PISSED!

On your Win2K box, go to 'Services' and
look for ping.exe.

Well it does not appear to be the
mail linux box as much as it is the dns server win 2000 what's
strange is I can physically unplug the cable from the box and the
outgoing traffic stops yet the incoming is still going??? I unplug
the wan and it goes away..

If you are running an old linux box that
you don't have a root password for, that means it is more than
likely out of date as far as patches go. That means it
could possibly be "Rooted" and that is not a good thing!!!
There are alot of DNS DDOS attachs out there, I would download
ethereal and watch the traffic VERY closely for a couple of
hours.

I have Brilan bandwidth control
and for kicks I put my servers behind it and just yesterday I
noticed that I have a steady 250kbps up and down on my DNS and
my mail server I unplug the Lan connection to my T-1 and the
problem goes away so I know it is not my wireless customers? I
did a sweep and found nor worms on my 2000 machine I do have
Linux 6.4 machine that I don't know root so cant run any kind
of scan but it appears that it is coming from the WWW? how can
I tell what IP or where this is coming from its almost like a
DNS??? things are functioning normal but a little slow since
this is taking some of the bandwidth?? can or would my ISP
(megapath) be able to tell where it is coming
from???
I have a strange feeling the WAR
has started between me and the competition since they
threatened to do something for their 3 customers jumping ship
and coming to me because of their poor service!
I have TCP IP Dump but cant
really see any thing specific to those IP
addresses??
