Anyone here from Orbitz?
by Andy Ringsmuth 28 Oct '15

28 Oct '15

Any chance someone on the list from Orbitz? Car rentals are suddenly impossible to book. It seems there’s a session timeout set to essentially zero. Selecting a vehicle returns this URL: http://www.orbitz.com/shop/home?errorId=3207 And an error of “We’ve noticed you’ve been away from this page for a while and your session has timed out. Please try again.” ---- Andy Ringsmuth andy(a)newslink.com News Link – Manager Travel, Technology & Facilities 2201 Winthrop Rd., Lincoln, NE 68502-4158 (402) 475-6397 (402) 304-0083 cellular

Re: *tap tap* is this thing on?

The reason they are the big boys is because they don't fund such operations. They see money before what you call obligations. Right or wrong they will sell a product if they think they can make it work. Making it work is all subjective. You say it means handling abuse complaints while they say it means the client being connected and able to ping the world. ------Original Message------ From: Rich Kulawiec Sender: NANOG To: nanog(a)nanog.org Subject: Re: *tap tap* is this thing on?

That excuse only works for so long. 1. It's not hard. It's far easier for large providers than small ones, although many of them flat-out lie and claim the opposite. 2. Whatever happened to "never build what you can't control?" If you can't stop your operation from emitting abuse, you should shut it down. Immediately. That's what professionals do. 3. Large providers pretend to be "leaders", but are among the worst in terms of actually leading by example. Just try getting a response from them via postmaster@ or abuse@. Of course these large operations should individually answer *every* message to those addresses promptly, 24x7, and initiate immediate investigation/remediation on *every* complaint. That's baseline operational competence 101, and given their enormous financial and personnel resources, it would require only a tiny amount of resources. But they don't -- and everyone else pays the price for it. ---rsk Regards, Dovid

IPligence?

Anyone have a contact for Ipligence, looks like a company out of Spain that does geoip database work. They have some issues with their database, and can't find a way to get in contact with them. They don't answer their support e-mails. Thanks, [DennisBurgessSignature] www.linktechs.net<http://www.linktechs.net/> - 314-735-0270 x103 - dmburgess(a)linktechs.net<mailto:dmburgess@linktechs.net>

[Discussion] MTU mismatch and impact of data-plane traffic
by Mohamed Kamal 27 Oct '15

27 Oct '15

Suppose you have the below network topology, where PE is connected to P1, P1 is connected to P2 and P2 is connected to GW, all through 1G links. [PE]-1500------------1500-[P1]-1600------------1600-[P2]-1500------------1600-[GW] The numbers represent the MTU values configured in the following order; PE's egress interface to P1, P1 ingress interface, P1 egress interface, P2 ingress, P2 egress and eventually GW ingress. Q1: What do you think would be the impact in terms of data-plane traffic (HTTP/s browsing, Video streaming etc), traversing this network, in the direction from the Internet and going to the PE router? My answer is: If there is a client running Win7 on a machine trying to access a web server out there, the TCP MSS would be adjusted to around 1260-1460 bytes depending on the Operating System's MTU value. Hypothetically, the first packet from the web server destined to the client would be 1460-bytes and will reach the ingress interface of the GW. The GW would receive it in the input_buffer of the ingress interface, strip off the Ethernet header, and move it to the output buffer of the egress interface whose MTU is 1600. Since the largest MSS is 1460, and there is always a one-to-one mapping between segments received from the TCP module and the packets constructed in the IP module, I believe that the largest IP packet would be 1480. GW would cram the Ethernet frame with the 1480-bytes of IP payload data and send it to the P2, which would in the other end, pass it on its way. Q2: However, what about larger MSS sizes? example; above 1500? and larges chunks of payload from a connectionless protocols that don't exchange MSS? UDP for example? or Google's QUIC (which is HTTP over UDP)? -- Mohamed Kamal
