Re: Scans Observed by Officer Friendly

One of the reasons I was so reluctant in going along with an online
database, not only being that spoofed ip's are going to fuzz up that
database, but the fact that scans, and attacks are indeed soooo prevalent
that I have yet to run into an ISP that does much more then sendout a
'canned response' to such activities.  There was a very short time that I
not only logged each offense, I would send logs and every little bit of
crap that I could to the abuse depts of these places.  There was only one
time that I got not only swift interdiction in such BS going on out here,
and was kept fully informed of the results of their investigation and the
resultant loss of acctounts to the offenders.  Of course, this was not do
to a mere probing, but a fullfledged DOS.  Damn, if I were to lodge
complaints about mere port scans, I'd perhaps be doing so 5-6 times a day,
on a slow one.  We still suffer hte occasional smurf, and do lodge
complaints of that magnitude, and still, recieve only 'canned replies'.
And since smurfs so well hide to offenders, even when one knows for a fact
where they orriginate, due to other activities, you'll find that the ISP's
are quick to 'chuckle' and just turn their heads away.

Good luck,

Ron DuFresne

I appreciate everyone's feedback regarding this observed scan. When I
wrote, I was confused by a DNS failure, apparently temporary, such that
nslookup didn't successfully resolve the address.

I have written to abuse () rr com and included the *full* logs. What I got
back was an automated response that effectively says thank-you, now go
away... which may be all that I can expect. We (at Syracuse) DO follow
through and "smack" people but I can't say that we always respond to the
original complaint with any follow through.

So how open is TimeWarner going to be to figuring out who had that
address at the time that you (don't) note and going out and smacking
someone upside the head? 

Quoting Randy Grimshaw (rgrimsha () mailbox syr edu):

Where would the address 24.93.46.49 be comming from?

Is this an annoyance or a masqerade?

My 'Officer' noticed BO_PING sweep and BO_FILEFIND attempts on Friday
night and Sunday night.
