[Int-area] Fwd: New Version Notification for draft-welzl-icmp-text-middleboxes-00.txt
Dear all, We just posted the draft below. Not knowing which other group would fit, we're sending it here. We're really transport people and at least I am newbie to this group... very curious to hear your thoughts: - completely idiotic? - exactly what the world has been waiting for? ... I guess it can only be one of the two above :-) If the chairs think that this makes sense to discuss in Prague, we'll be there, and I'd be happy to do a supershort presentation, but let us first hear what you think. It's a short and easy read, we promise that! :-) Thanks!

The text message is sent towards a destination but meant to be read by administrators of middleboxes along the path to the destination. The goal is to improve the user's experience with simple middlebox cooperation. Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.

ignoring for a second the question of information leakage which is apparently intentional in this case; an icmp message is unlikley to hash onto the same path that the offending/failed flow would have been on in many networks. While I can think perhaps more illustrative examples of uses for a free form txt field (DMARC for example). the notion that freeform txt messages with no source authetication should end up in a ticketing system in an actionable fashion seems extrodinarily unlikely.

When you say middlebox you're opening up the set that includes NATs, and that means any message that isn't to the same address/port pair isn't likely traverse the same path. So *at best* this might be able to contact the first middlebox it encounters, but how useful would that be with that limitation? (I'm also ignoring the fact that most middleboxes don't want to admit they exist, so this might be only providing another way for them to ignore you) Joe ___ Int-area mailing list Int-area@ietf.org https://www.ietf.org/mailman/listinfo/int-area

It's a short and easy read, we promise that! :-) Since you are requesting an ICMPv6 codepoint, I think 6man would be a better venue for this work if it progresses. As for the draft itself, I have a few thoughts. * It is unclear how the plaintext message ripples up to the administrator. Some clarity about this would be very useful. * What about DoS attacks? There is no rate-limiting? * Need to specify type128 for IANA * A +1 for Joel's and Joe's comments Thanks Suresh ___ Int-area mailing list Int-area@ietf.org https://www.ietf.org/mailman/listinfo/int-area
