Thanks to all who replied.

I feel that he may be a "good netizen" but is using the wrong approach.

I am going to filter the standard ports and go from there.

I did send him a another email questioning why he's running the scanner.

We had the same problem a few months ago, but in this case bring hundreds of

The solution was to filter in our main router the "standard" ports for
Netbus (12345) and BO (31337) both udp and tcp.

Then the only thing to resolve was our users disturbing between them, but
this is simpler because we know more or less each user profile and we can
act based upon that.

Hope this helps.

Subject: [NTISP] Opinion on Netbus/BO

My ISP has received 2 complaints from different people complaining that one
of my users is using netbus to attempt access to their systems. Both
complaints finger the same user different days though.

After the first complaint, I sent a notice to the user and this is the
response I got back. I am not that familiar with Netbus and want to know if
the customer sounds legit or is he blowing me off?

I've recieved the same messages myself and i have found that these
people are mistaking the netbus scanner in the script I use as an actual
attempt to connect with them. And i also get the complaints when i use
netbuster to protect myself from similar problems. I dont have any of
those types of programs nor do i have any use for them. I understand
your concern..I am sysop in a few chat rooms so i have to use some type
of protection from the people we have problems with. I've found that
most of the complaints i get are from people who simply just dont know
what they are seeing when they are scanned. I apolagize for any problems
that may arise from it .. but i do need to protect myself from those
programs also.
