Ditto for me. * Why does this modem have port 513 open? I can connect to it, but haven't yet succeeded in getting it to do anything useful, and I don't know what's listening, but it worries me, particularly as it's open on the HFC side too, which potentially exposes customers on the same network to each other's modems. Indeed, I can connect to port 513 on 60 modems in the same subnet as mine. This might possibly be due to lack of filtering by the ISP, since my test connections to those other modems were going via my default gateway. Alternatively, perhaps I am deceived and all these connections are being routed to a spy box somewhere, maybe in an attempt to prevent customers from using rlogin =). Somehow, that idea scares me even more.
