Your searching 'A' records which are not used for mail. Try MX records instead. Oh well... Mark, I'm going to reply to DH support, asking them to call you directly. In the meantime, can you telnet to mx1.postal.mail.dreamhost.net:25 and post what happens? _____________________

Okay, catching up with this thread:
Our ISP doesn't block traceroute; in fact, I don't know of many high-end ISPs who do. Just makes debugging harder, and the bad guys can map your network anyway. I can't establish a connection to mx1.postal.mail.dreamhost.net:25. This is almost certainly an IP block or router hiccough. Anyway, the whois contact information for dreamhost lists a phone number that goes straight to an answering machine. I'll leave a message, but I'm not confident that it'll get checked. |

blah blah blah I think if you bothered reading between the lines you would have realised that I pointed out there was an MX record. Just not an A record. Some systems don't work with email when no A record exists on the host name. Not a lot, but some. |

Just makes debugging harder, and the bad guys can map your network anyway. try traceroute microsoft.com traceroute yahoo.com traceroute ebay.com traceroute msn.com etc etc Everyone blocks traceroute. And so do you: Here's a traceroute from www.net.berkeley.edu to ns0.lindenlab.com http://www.net.berkeley.edu/cgi-bin/traceroute?ns0.lindenlab.com |

Here's an example of Ipswitch mail smtpd:
With the ip of the SMTP client: Query DNS for PTR record of ip (reverse lookup) Does the PTR record exist? No: reject mail. Does the PTR record refer to the HELO / EHLO hostname? No: reject mail. Does the ip address's "PTR hostname" have an A record?? No: reject mail. Does the ip address's "PTR hostname" have an MX record?? No: reject mail. http://bind8nt.meiway.com/itsaDNSmess.cfm |

The point is: set an A record for LSL.SECONDLIFE.COM

And so do you: Here's a traceroute from www.net.berkeley.edu to ns0.lindenlab.com http://www.net.berkeley.edu/cgi-bin/traceroute?ns0.lindenlab.com We're talking past each other. There are two types of traceroute. One uses UDP packets on high ports to generate ICMP Port closed responses, another just uses ICMP. On the Linux traceroute I have available, traceroute -I uses ICMP. I should have been more clear; that's the one that I usually use (actually, I usually use mtr, but you get the idea). But you're right, ebay, microsoft, and msn block both. It's their network and they can block ICMP if they want, but we chose not to since it makes debugging more difficult and doesn't actually help you very much. |

This is really becoming a problem. I have products that I can't release because of this. Mark, is there a status? Or do I need to find another web host and get off of Dreamhost?

I've had the same thought (leaving Dreamhost) but that raises the question of what to do the next time something like this happens. I'd hate to spend a lot of time (and more than a little money) moving all my domains and databases and crap to some other host, only to have this happen again. I totally agree. I really really don't want to have to go through the hassle and expense. But we are at 2 weeks of downtime here. I have to do something. I have one whole product line totally defunct. I am at wits end on this. And I think we have all been very patient so far. _____________________

Perhaps all the SL'ers whom host on Dreamhost should act in unison, just to draw more attention to this whole problem. I know of there is at least 38 SL'ers whom at least at one point had an account - I am sure there is more than that in total.

I'm a Dreamhost user. So far I have sat back through this episode, thinking it would be taken care of fairly quickly. I can see now thats not happening.
I signed up for their special a year ago with the crowd. They have been the best inexpensive web host I have ever used. They are totally responsive to my issues. They have added worthwhile upgraded features to my account every month I have been a member. Their documentation is awesome. My plan is a hundred times better than when I paid my initial $9.95, without me paying even another dime. I just re-signed with them for 2 years in advance. I highly suggest everyone who needs web hosting use them. In short they are the company I wish SL was. Dreamhost is providing the back end services to many SL scripters that Linden Lab should be providing themselves, and at a very affordable price. We are using this service because Linden Lab won't or can't offer it. You should be making superhuman efforts to fix any broken communications between Dreamhost and SL grid. If you need any information or assistance please feel free to contact me. _____________________

sapphire, perhaps you can start adding email addresses to the Trouble Ticket?
hiro dot pendragon at gmail dot com - and I will pull my hosting and badmouth them to friends if they can't resolve this. _____________________

I'm forwarding the DreamHost tech's latest traceroute to [email]noc@pnap.net[/email] to see if they have any ideas. If I don't get an answer I will try [email]noc@internap.com[/email]. (Mark, sorry if you are already talking to them about the issue.) Maybe that will help bring this outage to an end.

It is actually Hun's ticket. But why don't we try this? Everybody that is affected send an email to [email]support@dreamhost.com[/email] copying [email]support@secondlife.com[/email]. Subject: I have lost all communications between Dreamhost and Linden Labs Body: Approximately 2 weeks ago I lost all ability to communicate between dreamhost.com and lindenlab.com. The ticket # 1148608 has been opened with Dreamhost in reference to this. Mark Linden at Linden Labs has been working this from their side. Could you please let me know the status of this outage and what steps are being taken to resolve it? _____________________

Hello, Internap has received the following concern from a customer of yours that does not appear to be related to a problem with your Internap connectivity (routing or filtering). They request that you please confirm that you are not filtering their source address range, or confirm that you can reach their source, and respond back to their contact. In their trace below, the next responding hop would be from your LAN. If you have any questions or concerns please address them to [email]noc@internap.com[/email], or give us a call at one of the numbers below. Thank you, -mike _____________________________________________________________________ Mike Buschmann EMAIL: [email]noc@internap.com[/email] NOC Engineer PHONE: (206) 256-9500 / Network Operations Center (877) 843-4662 US Internap Network Services 00800-468-37627 UK It seems like either that border router is dropping outbound traffic to DreamHost, or DreamHost has some router that is dropping inbound traffic from Linden Lab. _____________________

Either that or they're just doing a UDP traceroute and not an ICMP one as Mark explained above.
border1.ge2-1-bbnet2.sfo002.pnap.net drops UDP tracroute packets, which is the default traceroute on linux You need to go tracroute -I in order to do an ICMP traceroute. |

This is the latest from Brian at DreamHost, a response to my request to call LL:
Hello, I only got a voicemail. There's not too much that we can do, as the block seems to be on their side. We don't block anything on this end. If you need anything else, please let us know. Thanks! Brian _____________________
