Sounds like a few people out there had a rough few days. I found this linked at the top of the paradise homepage. http://www2.paradise.net.nz/security_update/news.html Security Update Security issue - email and web hosting A small number of Paradise.net customers may have have experienced email delays and web-hosting problems on Thursday January 20th and Friday January 21st. Early Thursday morning some Paradise email was delayed. Our security people detected a security threat and disconnected a server to preserve the integrity of Paradise.net. This server will be reconnected shortly and backlogged email should be delivered this afternoon (Friday January 21). As part of our security precautions we also disconnected hardware which hosts Paradise web pages. We have been working round the clock to ensure the hardware can be reconnected with no risk to Paradise.net or Paradise users. We expect to restore web pages this evening. We know that an external party has attempted to interfere with Paradise.net. This attempt was picked up and immediate steps were taken to avoid any further impact on Paradise.net customers. Please accept our apologies for any inconvenience these very necessary steps have caused. Our approach, as always, is to take firm steps to preserve the security of Paradise.net and protect our customers. the team at Paradise.net -- Simon J.

Notification of NZRR Database changes
by NZRR Database Notifications 20 Jan '05

Dear Colleague, This is to notify you that some object(s) in NZRR database which you either maintain or are listed as to-be-notified have been added, deleted or changed. These objects are used to configure the various NZIX route servers (http://nzix.net/) so you can expect the relevant servers to be reloaded in the near future. The reloading of the servers is staggered over a period of time so that if you are peering with both servers at an exchange, you can maintain at least one BGP session at all times and consequently a full set of routes. The update causing these changes had the following mail headers: - From: Andy Linton <asjl(a)citylink.co.nz> - Cc: - Subject: - Date: Fri, 21 Jan 2005 13:15:27 +1300 (NZDT) - Msg-Id: <Pine.LNX.4.58.0501211313160.7621(a)jennings.citylink.co.nz> NZRR Database Notification Department --- OBJECT BELOW DELETED: route-set: AS9439:RS-ROUTES:AS23959 descr: Route set advertised to WIX by Catalyst-IT - AS23959 members: 202.49.159.0/24^24-29, 202.46.190.0/24^24-29, 202.20.6.0/24^24-29, 203.167.212.32/29, 203.167.247.160/29, 202.7.4.64/29 admin-c: RPA1-NZRR tech-c: RPA1-NZRR notify: rpsl-admin(a)nzix.net notify: nznog(a)list.waikato.ac.nz notify: andrew(a)catalyst.net.nz mnt-by: MAINT-NZRR-NZ changed: rpsl-admin(a)nzix.net 20040120 changed: rpsl-admin(a)nzix.net 20040628 source: NZRR

Technically, you can still be pass traffic to the client's endpoint, although the path selected may not be optimal. What can cause issues is if you then start creating routing policies on your route reflectors based on AS-path, especially if you don't have a direct peer with both of the providers that are carrying that customer's traffic. With multiple peering points, you can end up backhauling the traffic over your own links because the routing decisions passed via your IGP are no longer necessarily optimal e.g. I may wish to pass a 10Mbit stream from a Wellington customer to somewhere else in Wellington, via another provider, but the route reflectors see that destination as having a shorter AS path via Auckland. We don't have a destination AS that a metric can be applied to. We can of course apply different costs to the WAN links (and should have done), but the fine-grained control of traffic isn't achievable because the router can't be given much to go on. Policy routing and tagging is an option, but relies on the destination site, who is not necessarily a customer of ours, informing us of changes in their topology so our rules can be updated. APNIC have always been very good when it comes to getting ASN's; I've always found the justification of additional address space to be an ordeal though :-) In my opinion, it would be far more preferable if APNIC allocated an ASN when a customer was given an independent address assignment. After all, the reason that most want independantly allocated space is to multihome... Cheers, Gordon

National BGP routing
by Gordon Smith 18 Jan '05

18 Jan '05

I'm sure I can't be the only one that notices the BGP inconsistancies in their route tables.... Seeing the latest NZRR update prompted me to check the BGP tables again... We do not and will not accept route advertisements containing private AS numbers from our peers. The reason we don't is the same reason we don't route RFC1918 space externally... If a customer has their own address space and wants to multi-home, they should also have their own AS. Advertising up private AS numbers that should really remain within the network isn't a solution. Inconsistant AS-paths are bad enough, without creating additional problems... At least we're only seeing 5 class C's being advertised at the APE with inconsistant AS-paths at the moment. Perhaps BGP routing could be a topic for discussion at NZNOG 2005? Cheers, Gordon

Xtra in the SpamHaus SBL
by Peter Macaulay 17 Jan '05

17 Jan '05

I don't know if anyone from Xtra reads this list - trying to get through to anyone who has even an iota of understanding about this type of thing by phone appears to be almost impossible. Xtra has managed to get itself into the SBL realtime blocklist - http://www.spamhaus.org/sbl/sbl.lasso?query=SBL22816 It appears that someone objected to some promotional material sent out by the "House of Travel" travel agent group and has ended up blocking them; this means that one of Xtra's MX (mail exchanger) servers is now blocked by anyone who uses the SBL as a spam filter. If anyone knows anyone at Xtra who can do something about this, could you pass this message on? It's probably inconveniencing a reasonably large number of people. The NZNOG list would be a good place to post this too, I suppose, but I'm not a subscriber.

(OT) Getting to NZNOG '05
by Jeremy Naylor 16 Jan '05

16 Jan '05

Hey guys, For people who want to know about how to get to the NZNOG '05 conference, you might want to catch the Overlander train that Tranz Scenic run. There's 2 every day (1 from Wellington - Auckland & 1 from Auckland - Wellington). You can get more info about these trains if you want to on Tranz Scenic's web site, at: http://www.tranzscenic.co.nz/services/overlander.aspx Hope this helps. Thanks, -- Jeremy Naylor p: +64 21 374 689 e: jeremy.naylor(a)r2.co.nz w: http://www.r2.co.nz/~jeremy w: http://e-living.wellington.net.nz -- No virus found in this outgoing message.
