Re: FC: Email a RoadRunner address, get scanned by their securitysystem]
I only find it humorous that a majority of the network probes against my network come from RoadRunner cable modems as it is, yet they want to add to it by having their own server run a probe... RR scans their own network far more intrusively than they scan outside mail senders and thwack their own users all the time, only of course nobody hears about that. As I've said elsewhere, most of a network's real mail comes from places that have sent mail before. If you get mail from a host that's never sent you mail before, it is far more likely to be a compromised relay or proxy sending spam than a legit mail server. Of course they test it. Put yourself in their shoes. They have a network with tens, probably hundreds of thousands of users, all with a swell high-speed connection, all under continuous attack by various sorts of malware. Most of the users are running Windows 98 or XP systems which are at least 30 critical security patches (that is to say, more than a month) out of date. Realistically, what would you do? -- John R.

But what we need is a way for 10/100 Mbps 1500 byte hosts to live with 1000 Mbps 9000 byte hosts on the same subnet. I thought IPv6 neighbor discovery supported this because ND can communicate the MTU between hosts on the same subnet, but unfortunately this is a subnet-wide MTU and not a per-host MTU, which is what we really need. A decade ago, when I designed SIPP Neighbor Discovery, it saved per destination maximum unfragmented datagram size in the route cache, and each I-Am-Here message Heard specified Maximum Receive Unit (MRU) per host. Thus, once upon a time, IPv6 had what you need. Unfortunately, the IPv6 group stripped out such innovative features. I stopped paying attention after the new editor stated something like it worked for ethernet, we really don't need any more than that. Well, we used IPv4 from '83, and designed SIPP (cum IPv6) in '93. IPv6 is a failure -- maybe it's time for this decade's design? Or maybe even some of the features some of us thought we needed a decade ago? -- William Allen Simpson Key fingerprint = 17 40 5E 67 15 6F 31 26 DD 0D B9 9B 6A 15 2C 32

Recent equipment in Asia uses a modified coax along the subway lines to leak EM into the tunnels. 100% reception is expected in most Asian metro/subway lines. That has provided some thought, such as providing 802.11b access on the subways. --
