Re: [tor-relays] Again: abuse email for non-exit relay (masergy)

[ronqtorrelays@xxxxxxxxxx]

I got a *bunch* (harassment-level) of telephone calls from my ISP similar to this. They refused to do anything by email, and wouldn't tell me anything more about the supposed port-scanning attacks. They just kept asking me to "make sure Windows and my router firmware were up to date." (No Windows, no router.) They kept saying that I was port-scanning a machine in the 10.x address space. When I finally got someone who knew enough to know that wasn't a routable address, they *still* couldn't tell me anything about the nature of the complaint. I finally had to threaten legal action, at which point they *still* refused to disclose anything about the complaint, but at least stopped calling me. The *hours* on the phone revealed only two things: the complaint was originating from somewhere in the Chicago (US) area, and the "port" I was "scanning" was always 9002.

My relay was also a non-exit. Needless to say, I was monitoring my network traffic and there was no "port scanning" going on. My best guess is that some kindergartener in a sysadmin suit (or incompetent security suite vendor, if that's not redundant) configured a firewall to automatically report accesses via port 9002 as port scanning and they have a relay behind said firewall.

As much as I would have welcomed the opportunity to educate and assist the operator of this misconfigured security system, my ISP would never divulge any contact information.

Just a data point.
