Where did sbcglobal.net go?

Does anyone know if SBC/PacBell dropped the sbcglobal.net domain name? Since late yesterday, it's been gone from the root nameservers..... $ dig @a.gtld-servers.net -t ns sbcbglobal.net ; <<>> DiG 9.2.0 <<>> @a.gtld-servers.net -t ns sbcbglobal.net ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 28110 ;; flags: qr aa rd; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 0 ;; QUESTION SECTION: ;sbcbglobal.net.

NSI's primary MX mail servers aren't functioning. We've had problems sending mail since approx. 1800 EST yesterday. We've tested from 4 seperate physical networks all seem to be using alter.net to reach NSI. I tried calling but can't reach anyone with a clue. Len

Routing problem
by Arturo Lev Servin Niembro 11 May '02

11 May '02

Hi, I have a strange question because this is not very common. Lets asume the following scenario to simplify it: net A -- RTA --- RT1-ISP1 --- IP Cloud --- RT2-ISP1 -- RTB -- net b --- RT1-ISP2 --- IP cloud --- RT2-ISP2 -- RTA and RTB are in differents ASs. ISP1 is preferred via BGP (local preference). Sometimes we lost reachability between net A and net B but we can stiil see the routes trough ISP1, so the BGP can not converge to ISP2. The problem is because the ISP1 have troubles with their IP-MPLS network, so, sometime they lost traffic. Do you now about some trick that can be used to know that the path to net b is not good despite the route is still in RTA? I was thinking to force the loopback from ISP1 to be learned in RTA to some route learned from RTB, but how. I think that if I make a tunnel interface it would still depend from BGP to work and BGP depend form tunnel, so it would not work. Any idea that do not imply to change ISP1 nor use ISP2 as default? Thanks in Advance, -as

OT: Changing NIC handle info
by Jason Lewis 11 May '02

11 May '02

I can't find info on network solutions website for changing info for my NIC handle? What is the deal? I figured I would send an empty messages to hostmaster(a)networksolutions.com and get some info, but the email it send back is full of dead links. For the life of me, I can't find and info on where all the templates are. Anyone still using the templates? jas

Re: Earthlink SMTP for Mobile Users
by Crist J. Clark 10 May '02

I was stuck in a dial-up-only hell for a few months and used quite a bit of Earthlink dial-up. I during that time, I did a variety of tinkering of the email headers (like masquerading envelopes). It sure didn't seem to me that Earthlink cared at all what domain was in the return path. Their SMTP servers would relay _anything_ provided you're source IP was in their IP-space. So, AFAIK, you can do whatever you want with respect to outgoing mail (any source domain in the envelope or headers that you want) and Earthlink's SMTP servers will relay it. Not that I didn't get annoyed with the blocking from time to time. Sometimes I wanted to talk directly to a remote SMTP server with telnet to debug a client's setup or see if they were the open relay I was getting SPAM from. IIRC, you get ICMP admin-prohibited messages back when you try to connect to port 25. But I probably have to say that I think Earthlink is doing the right thing, IMHO. Aren't the other big US dial-up providers doing this kind of thing? I assumed they all were. Despite the continuous rise in total SPAM levels, don't see very much SPAM from the US mega-huge dial-ups anymore. -- Crist J.

Earthlink SMTP for Mobile Users
by Cutler, James R 10 May '02

10 May '02

Jim, Yes, SMTP settings will to have to be changed to match whatever service, different from Earthlink.net, that you happen to use. As an outlook user, I simply created multiple profiles which referred to the same local mail store. This technique even works with the VPN to the corporate Exchange system. I just click the correct shortcut (alias) to activate the correct configuration for my connection status. My experience with Earthlink.net using several domains has been quite positive. My understanding is that Earthlink can support this because the subscriber connection itself is authenticated, giving the required traceback to the end user for UCE policy enforcement.

Thank you! One clarification: Can these users relay through that host, using SMTP AUTH, from anywhere, or only from within your network? I observe, for instance, that the instructions for Outlook 2000 (Windows) does not have them check "my [outgoing SMTP] server requires authentication". If the former, great! I'll inform my affected customers. If the latter, they'll have to fool with settings as they move around -- which you no doubt already know is asking too much of 99% of the population. :-)

Effects of de-peering... (was RE: ratios)
by James Smith 10 May '02

10 May '02

>> >> I apologize in advance, I'm a total newbie...so what did you have to do? > >Build resilience into his single homed, single point of failure >non-redundant network. > >Steve > ============================================= Maybe it is possible he made a business decision based on the long term costs involved with multihoming/redundancy vs. the loss of near total reachability. He may have come to the conclusion that the probability of that scenario occuring was not sufficient reason to multihome. His call. I think we all assume that our provider "guarantees" us some sort of "total reachability". Near as I can figure, they do not. Therefore, you buy a pipe into their network based on percieved and actual connectivity and hope that the situation remains static at best. Does ANY provider give a "reachability" guarantee? James H.
