RE: Hotmail blackholing certain IP ranges ?

2007-04-25 Thread Gabriel Kuri

I've had the same issue with hotmail when email originates from
208.127.57.0/24. any mail sent from a server within that netblock is
properly accepted by hotmail, given a queue id, but disappears and is
never delivered.

if anyone from hotmail has a clue as to what's going on, it would be
appreciated.

thanks much ...

 Subject: Hotmail blackholing certain IP ranges ?
 
 
 Does anyone have a clue why hotmail is appearantly blocking 
 certain IP ranges ?
 
 I provided a new server for a customer in his own IP subnet which is 
 a part of a /20 we announce, but for some reason all mail sent to 
 @hotmail.com addresses disappears.
 
 He has another server in a /24 we announce which is still part of 
 another network and that works like a charm.
 
 None of our subnets are blacklisted in any spamfilter I can find, so 
 i'm a bit puzzeled on what's up here.
 
 If any hotmail netadmin is reading this list, can you please check if 
 81.26.212.0/26 is blocked in any way (It's part of 81.26.208.0/20 
 originating from AS39556)
 
 According to the mailserver logs all the mail is properly accepted by 
 the hotmail relays, never to be seen again after that.

swamp space reachability

2005-05-13 Thread Gabriel Cain

Hi all.
I have a bit of an issue.  A while ago, I was issued 204.8.0.0/22 from ARIN 
(under ipv4 policy, 4.2.1.5 - the minimum allocation for multihomed 
networks).  I've just gotten around to announcing it to migrate off of my PA 
space.  In testing, I've determined that a number of networks are 
blackholing my traffic.  I've started attempting to contact the various 
networks that appear to be blocking my traffic, but that's not going 
particularly fast.

My question:  Has anyone else who has received a small allocation from ARIN 
had this happen to them?

If you'd like to look and see if you see my announcement, I'm announcing 
204.8.0.0/22, as well as the four /24s that make it up (the deagg is 
temporary and to see if it helps, I'm well aware that aggregating is 
preferred).  My AS is 30233.

Thanks!
Gabriel
P.S. To those of you who will be at NANOG 34 this Sunday, I look forward to 
meeting you guys.

It has helped me a lot.

Same here...   We saw all our AIM clients go down for about five minutes. 
Traceroutes showed lots of apparent troubles in atdn.net, also coming from

Is anyone seeing issues with AOL CNN ?

Your analogy is flawed.  The problem is, most people don't realize that:

Unique AS

2003-07-13 Thread Adonaylo, Gabriel

Hello All,

First of all, forgive my English writting please!

I work for an Internet Carrier in Argentina which is in process of
reorganizing its regional operations. We are also serving in other
countries in South America.
 
We currently have one AS per country and we are looking forward to
migrate to a unique AS for all the organizations.
 
Could anyone describe pros and cons of having a unique AS for this
kind of networks rather than having one AS for each country. Regardless of
the cons, we are facing migration process anytime soon, so I would
appreciate very much to get more pros than cons to include in my papers
which are almost finished!

I would also be glad if you share your experience about this migration
process. That is the real value of your answers.
 
Thanks for your time.
 
Regards, Gabriel.

Cross country networks, and data replication... Questions... :-)

2003-01-16 Thread Gabriel


Hello all.

--- Where we are ---

Currently, I've got a single site, colocated on the East Coast. 
Currently, I've got two NetApps at that site, one serving as a 
mailspool, the other serving as a location for web documents.  This 
system works via NFS to a fair number of mail and web servers, and it's 
running happily.

--- Where I'm going ---

What I seek is some help on implementing a second site, and the link 
between the two.  The sites will be more or less the same in terms of 
the equipment in them, or so I hope.

I want to be able to have the changes made at one site replicated to the 
other site transparently.  That is, if I update a file at site A, I want 
to be able to see the changes at Site B in a reasonable period of time 
(i.e., short), and without having to manually move data around.   I 
specifically want to do this for allow both sites to offer the same 
mailspool, so that customers can check their mail at either site.

I am in the planning phase of bringing up a second site, and at this
site, there will be more web servers, and more mail servers.  There will
also be an additional netapp for each of mail and www.

Between the pair of mail netapps (and to a lesser degree, the www
netapps), I want them to replicate changes to the other one.  That is,
if a file is removed on Mail.NetApp A, it should also disappear on
Mail.NetApp B.  And if a file is created on netapp B, it should also
come into existance on netapp A.  Bidirectional updates.

My current setup consists of Linux and FreeBSD systems, and F740 NetApps.

And yes, there is a lot of pressure to stay with the NetApps.

Any hints, or advice will be much appreciated.

Thanks in advance,
Gabriel

IWon/Excite mail admin...

2002-12-18 Thread Gabriel


Hello all,

I've been trying (rather unsuccessfully) to get a hold of iwon/excite. 
They're blocking my mail servers (safepages.com domain), and I'd like to 
talk to them about it.

My question:

Does anyone have a NOC or mail admin contact for Excite/Iwon that they 
would be willing to share?

(And to reciprocate, if anyone has been getting spam from my domain, I'd 
love to talk about it so I can shut down offending user.)

Thanks.
