Hi There :)

We are having some major issues over the past week when forwarding
mail to xtra. Mainly:

- delivery temporarily suspended: connect to mta.xtra.co.nz
- connect to mta.xtra.co.nz[210.54.141.1]: server dropped connection
without sending the initial SMTP greeting

Has anyone seen any of these issues and knows anything about them?

I just trying to contact XTRA's administrators, but no response. I
have had a good response back from the corporate side of XTRA, which
is assuring.

Regards and Thanks,

Simon

I've been seeing similar issues, such as

2006-12-07 14:13:36 1Gs4Fp-0000gi-Vv SMTP error from remote mail server
after initial connection: host mta.xtra.co.nz [210.54.141.1]: 421
Service not available

2006-12-07 14:13:36 1Gs4Fq-0000hO-Ut mta.xtra.co.nz [210.54.141.1]
Connection refused

2006-12-07 12:03:52 1Gs4YH-0002YT-Qz mx1.xtra.co.nz [210.54.141.1]
Connection reset by peer

2006-12-07 12:34:26 1Gs4Ll-00049D-Hg Remote host mx1.xtra.co.nz
[210.54.141.1] closed connection in response to initial connection

I haven't bothered to question why as it isn't posing a problem for us, yet.

Checking my logs for today I've had the same issue since midnight and
probably yesterday too:
2006-12-07 12:19:26 1Gs4kg-000GHZ-KO Remote host mta.xtra.co.nz
[210.54.141.1] closed connection in response to initial connection

The company my partner works for has their domain and email with Xtra and
they've been having email issues for the last 48 or so hrs, every 4-8 hrs
email trickles through.

So IMHO i'd say there is a problem xtra wide.

Barry

Yes. I do a bit of mail to Xtra each day, and notice that roughly 1 in 6
connection attempts are refused.

I originally noticed that this happened when sending a `newsletter' type
email (solicited opt-in) out last Tuesday (I think), so wrote it off as
some kind of anti-spam thing.

I notice that when I telnet (tried just now) to mta.xtra.co.nz on port
25 it refuses roughly 1 in 6 times.

What is the response from the corporate side? You mention that it is
`good', but yet you still feel a need to `escalate' to the list?

Has anyone seen any of these issues and knows anything about them?
We are also seeing issues since late November. I emailed
***@xtra from elsewhere on 1 December, with no response so far.

Typical log:
Dec 7 14:19:26 skinner postfix/smtp[19226]: connect to mta.xtra.co.nz
[210.54.141.1]: server dropped connection without sending the initial
greeting (port 25)

Typical telnet:
$ telnet mta.xtra.co.nz 25
Trying 210.54.141.1...
Connected to mta.xtra.co.nz.
Escape character is '^]'.
Connection closed by foreign host.
$

The above is the most common behaviour, but apparently the connection
does stay open properly from time to time (I had to send a bunch in a
row to get this):

Dec 7 14:28:34 skinner postfix/smtp[19322]: 187FFA9EF2B:
to=<***@xtra.co.nz>, relay=mta.xtra.co.nz[210.54.141.1],
delay=27, status=bounced (host mta.xtra.co.nz[210.54.141.1] said: 550
Invalid recipient: <***@xtra.co.nz> (in reply to RCPT TO
command))

We also sometimes get "421 Service not available" before it drops the
connection, and sometimes we even get connection refused. But when
we're really lucky:

220 mta01.xtra.co.nz ESMTP server ready Thu, 7 Dec 2006 14:41:34 +1300
220 mta06.xtra.co.nz ESMTP server ready Thu, 7 Dec 2006 14:43:01 +1300

So, yeah, it looks like something might be up.

It's been a problem over the last week (maybe more). Xtra email
server(s) at the ip you mention refusing connections, or the last one I
had a few minutes ago was 421 Service not available.

I placed a call with Xtra's "Complex Technical Support" a few days ago
and they told me that due to the volume of spam they are receiving they
have reduced the number of concurrent incoming connections that the
servers are allowing.

While I think of it, Network Operators who are VoIP capable may wish to
use the INOC-DBA service.

http://www.pch.net/inoc-dba/

We're on it and wishing there were more NZ operators who were. We could
then ring each other and talk about beer.

i would say autonomous networks who are IP capable, with decent OS+
soft phones too can join the fun.

Hi,

I'm possibly about to sign up to the INOC-DBA service, but just wanted to
clarify (as we are setting up an Asterisk server for SIP and PSTN calls) how
would the directory service be set up to call other autonomous systems?
Would it be using an ENUM like DNS service?

Eg:

enum.conf:
---
[general]
search => e164.arpa
search => inoc-dba.dns.server
---
Sounds like an excelent way for NOC staff to easily contact others via
ASN's.

Regards,

Nick Larsen

No, it's even simpler than that. The ASN is the phone number - so
you simply send a call to ***@your-inoc-dba-sip-peer.

https://www.pch.net/inoc-dba/docs/asterisk-inoc-mini-howto.txt is a
pretty good start. Give me a buzz off list if anything doesn't make
sense to you.

Cheers,
Jonny.

A slightly more detailed howto also exists.
https://www.pch.net/inoc-dba/docs/asterisk-inoc-howto.txt

As for directory service, we have a rather crude xml based directory
service. the URL for the directory is
http://www.pch.net/inoc-dba/xml-directory/index.php

thanks

Given that Gaurab is (I believe?) coming out to NZNOG in January, would
a presentation/tutorial on using INOC DBA be worthwhile then?

I think it would. I've been contemplating doing one in the past along
the lines of:

. A live demo of inoc-dba in action
. The unpacking and live configuration of an IP phone from DSE (radio
shack for those overseas) onto the inoc-dba network.
. URL with configs for cisco/linksys/grandstream phones
. An example of how to configure the trixbox live CD to connect.

We've had powerpoints about inoc in the past and while interesting -
they don't get people to actually do it.

If you can show people that in less than 5 mins - you can configure a
phone you just bought, to be able to talk to the other NOC people in the
country, then it's worth it.

I'm willing to help with the physicals if Gaurab wants to do the talking.

Yes, Happy to get it done at NZNOG. no problems. I can bring over the
WiFi sip phone as well, to add to the fun.

For past few years, at APRICOT and SANOG, we have put an INOC DBA
phone near the conference NOC area, both as a way to talk to other
NOCs as well as demonstration of the system. Something like that
would be good idea for NZNOG as well.

I think finding hardware wont' be an big issue at all.

thanks

This is exactly what I am seeing also. I think this is affecting so
many folks now that it's about time Ted or someone else from Xtra
explained what's going on.

This is exactly what I am seeing also. I think this is affecting so
many folks now that it's about time Ted or someone else from Xtra
explained what's going on.
Since 0630 this morning my MTA has logged 142 failed connection attempts
similar to this:

Dec 9 12:44:00 maverick qmail: 1165621440.510720 delivery 6790: deferral:
Connected_to_210.54.141.1_but_connection_died._(#4.4.2)/

In comparison, I have logged 18 successful deliveries.

By my calculations that means that Xtra are deferring more than 85% of
inbound mail connections.

However, to their credit, their "MOTD" such as it is @
http://xtra.co.nz/help was updated very shortly after James's post - so at
least theyre acknowledging the issue.
That said, walking back through my logs over the last week, that error has
been popping up very often....

I walked back through my mail logs and the first occurrance was around
0210hrs on November 27th.

Two weeks?

Why is it when it was happening to IHUG the Media / general public were
over them like a rash, but when its telecom people seem to take it.

I just wonder if its because people are so used to being shafted by
Telecom they cant be bothered complaining because they know it will get
them no where.

Arr.. god bless the Telecommunications Amendment Act that was passed..

Perhaps it's because people have acquired the habit of not using
their ISPs for e-mail, and are instead using gmail/hotmail/yahoo/
whatever.

I struggle to think of any of my non-technical friends or relatives
that use IMAP or POP for mail with their ISP's servers, for example.
Most of them seem to use Yahoo! through a browser.

(Come to think of it, none of my technical friends use their ISP's
mail servers either. They either run their own, or they use mine :-)

In that context, an inability to exchange packets with the rest of
the world is a far more serious problem than even a long-standing
problem with an ISP's mail platform.

There may be some element of customers being resigned to a "best-effort"
service, but I see that Auntie Hairoiled picked up on the story:
