IOS Vulnerability
by Arron Scott 16 Jul '03

16 Jul '03

As mentioned by Joe, Cisco has just announced a vulnerability that affects all versions of IOS, on any device, switches and routers. In the first instance, it is important to note that there are currently NO known exploitations of this vulnerability, and we are announcing it after building and preparing the appropriate fixes for all current platforms. Fixes have been made available regardless of whether your routers are under a maintentance support contract or not. The following URL also defines how to build Access-lists that can protect you from this vulnerability. http://www.cisco.com/warp/public/707/cisco-sa-20030717-blocked.shtml Do not panic, if you need more detail, feel free to give me a ring. If you can find an opportunity we would recommend an upgrade, but this is out of caution rather than need. Hope this helps to clarify the situation Arron Scott Cisco NZ *********************************************************************** Arron Scott (CCIE #4099) Phone: +64-9-3551951 Systems Engineer Mobile: +64-21-883163 Cisco New Zealand mailto:ascott(a)cisco.com http://www.cisco.com ***********************************************************************

Cisco Security Advisory: Cisco IOS Interface Blocked by IPv4 Packet
by Cisco Systems Product Security Incident Response Team 16 Jul '03

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Cisco Security Advisory: Cisco IOS Interface Blocked by IPv4 Packet Revision 1.0 ============ For Public Release 2003 July 17 at 0:00 UTC (GMT) - -------------------------------------------------------------------------- Please provide your feedback on this document. - -------------------------------------------------------------------------- Contents ======== Summary Affected Products Details Impact Software Versions and Fixes Obtaining Fixed Software Workarounds Exploitation and Public Announcements Status of This Notice: INTERIM Distribution Revision History Cisco Security Procedures - -------------------------------------------------------------------------- Summary ======= Cisco routers and switches running Cisco IOS® software and configured to process Internet Protocol version 4 (IPv4) packets are vulnerable to a Denial of Service (DoS) attack. A rare sequence of crafted IPv4 packets sent directly to the device may cause the input interface to stop processing traffic once the input queue is full. No authentication is required to process the inbound packet. Processing of IPv4 packets is enabled by default. Devices running only IP version 6 (IPv6) are not affected. A workaround is available. Cisco has made software available, free of charge, to correct the problem. This advisory is available at http://www.cisco.com/warp/public/707/cisco-sa-20030717-blocked.shtml. Affected Products ================= This issue affects all Cisco devices running Cisco IOS software and configured to process Internet Protocol version 4 (IPv4) packets. Cisco devices which do not run Cisco IOS software are not affected. Devices which run only Internet Protocol version 6 (IPv6) are not affected. Details ======= Cisco routers are configured to process and accept Internet Protocol version 4 (IPv4) packets by default. A rare, specially crafted sequence of IPv4 packets which is handled by the processor on a Cisco IOS device may force the device to incorrectly flag the input queue on an interface as full, which will cause the router to stop processing inbound traffic on that interface. This can cause routing protocols to drop due to dead timers. On Ethernet interfaces, Address Resolution Protocol (ARP) times out after a default time of four hours, and no traffic can be processed. The device must be rebooted to clear the input queue on the interface, and will not reload without user intervention. The attack may be repeated on all interfaces causing the router to be remotely inaccessible. A workaround is available, and is documented in the Workarounds section. The following two Cisco vulnerabilities are documented in DDTS. CSCea02355 ( registered customers only) affects all Cisco routers running Cisco IOS software. CSCdz71127 ( registered customers only) was introduced by an earlier code revision. Any version of software which has the fix for CSCdx02283 ( registered customers only) is vulnerable. Registered customers can find more details using the Bug Toolkit at http://www.cisco.com/cgi-bin/Support/Bugtool/launch_bugtool.pl ( registered customers only) . To identify a blocked input interface, use the show interfaces command and look for the Input Queue line. If the current size (in this case, 76) is larger than the maximum size (75), the input queue is blocked. Router#show interface ethernet 0/0 Ethernet0/0 is up, line protocol is up Hardware is AmdP2, address is 0050.500e.f1e0 (bia 0050.500e.f1e0) Internet address is 172.16.1.9/24 MTU 1500 bytes, BW 10000 Kbit, DLY 1000 usec, rely 255/255, load 1/255 Encapsulation ARPA, loopback not set, keepalive set (10 sec) ARP type: ARPA, ARP Timeout 04:00:00 Last input 00:00:41, output 00:00:07, output hang never Last clearing of "show interface" counters 00:07:18 Input queue: 76/75/1091/0 (size/max/drops/flushes); Total output drops: 0 ^^^^^^^^^^^^^^ ---> blocked Impact ====== A device receiving these specifically crafted IPv4 packets will force the inbound interface to stop processing traffic. The device may stop processing packets destined to the router, including routing protocol packets and ARP packets. No alarms will be triggered, nor will the router reload to correct itself. This issue can affect all Cisco devices running Cisco IOS software. This vulnerability may be exercised repeatedly resulting in loss of availability until a workaround has been applied or the device has been upgraded to a fixed version of code. Software Versions and Fixes =========================== Each row of the table describes a release train and the platforms or products for which it is intended. If a given release train is vulnerable, then the earliest possible releases that contain the fix and the anticipated date of availability for each are listed in the Rebuild, Interim, and Maintenance columns. In some cases, no rebuild of a particular release is planned; this is marked with the label "Not scheduled." A device running any release in the given train that is earlier than the release in a specific column (less than the earliest fixed release) is known to be vulnerable, and it should be upgraded at least to the indicated release or a later version (greater than the earliest fixed release label). When selecting a release, keep in mind the following definitions: * Maintenance Most heavily tested and highly recommended release of any label in a given row of the table. * Rebuild Constructed from the previous maintenance or major release in the same train, it contains the fix for a specific vulnerability. Although it receives less testing, it contains only the minimal changes necessary to effect the repair. Cisco has made available several rebuilds of mainline trains to address this vulnerability, but strongly recommends running only the latest maintenance release on mainline trains. * Interim Built at regular intervals between maintenance releases and receives less testing. Interims should be selected only if there is no other suitable release that addresses the vulnerability, and interim images should be upgraded to the next available maintenance release as soon as possible. Interim releases are not available through manufacturing, and usually they are not available for customer download from CCO without prior arrangement with the Cisco Technical Assistance Center (TAC). In all cases, customers should exercise caution to be certain the devices to be upgraded contain sufficient memory and that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, contact the Cisco TAC for assistance, as shown in the section following this table. +------------------------------------------------------------------------+ |Train |Description of |Availability of Fixed Releases | | |Image or Platform| | |------------------------+-----------------------------------------------+ | 11.x based releases | Rebuild |Interim| Maintenance | |------------------------+-------------+-------+-------------------------+ |11.1CA| |11.1(36)CA4**| | | |------+-----------------+-------------+-------+-------------------------+ |11.2 | |11.2(26e)** | | | |------+-----------------+-------------+-------+-------------------------+ |11.2P | |11.2(26)P5** | | | |------+-----------------+-----------------------------------------------+ |11.3 | |Not scheduled | |------+-----------------+-----------------------------------------------+ |11.3T | |Not scheduled | |------------------------+-----------------------------------------------+ |12.0 based releases |Rebuild |Interim|Maintenance | |------------------------+-------------+-------+-------------------------+ | |General | | | | |12.0 |Deployment | | |12.0(26) | | |release for all | | | | | |platforms | | | | |------+-----------------+-----------------------------------------------+ |12.0DA|xDSL support: |Migrate to 12.2DA; 12.2(10)DA2 - Aug-15-2003, | | |6100, 6200 |12.2(12)DA3 - Aug-22-2003: Engineering | | | |Specials available on request. | |------+-----------------+-----------------------------------------------+ |12.0DB|Early Deployment |Migrate to 12.3(1a) | | |6400 UAC for NSP | | |------+-----------------+-----------------------------------------------+ |12.0DC|Early Deployment |Migrate to 12.3(1a) | | |6400 UAC for NRP | | |------+-----------------+-----------------------------------------------+ | | |12.0(24)S2 | | | | | |12.0(23)S3 | | | | | |12.0(22)S5 | | | | | |12.0(21)S7 | | | | | |12.0(19)S4 | | | | |Core/ISP support:|12.0(18)S7 | | | |12.0S |GSR, RSP, c7200, |12.0(17)S7 | |12.0(25)S | | |c10k |12.0(16)S10 | | | | | |12.0(15)S7 | | | | | |12.0(14)S8 | | | | | |12.0(13)S8 | | | | | |12.0(12)S4 | | | | | |12.0(10)S8 | | | |------+-----------------+-----------------------------------------------+ |12.0SC|Cable/broadband |Migrate to 12.1(19)EC | | |ISP: ubr7200 | | |------+-----------------+-----------------------------------------------+ |12.0SL|100000 ESR:c10k |Migrate to 12.0(23)S3, **12.0(17)SL9 - | | | |Jul-15-2003 | |------+-----------------+-----------------------------------------------+ |12.0SP|Early Deployment |Migrate to 12.0(22)S5 | |------+-----------------+-----------------------------------------------+ | |Early Deployment |12.0(21)ST7 | | | |12.0ST|release for Core/|12.0(20)ST6 | | | | |ISP support: GSR,|12.0(19)ST6 | | | | |RSP, c7200 |12.0(17)ST8 | | | |------+-----------------+-----------------------------------------------+ |12.0SX|Early Deployment |Migrate to 12.0(22)S5 | |------+-----------------+-----------------------------------------------+ |12.0SY|Early Deployment |Migrate to 12.0(23)S3 | |------+-----------------+-----------------------------------------------+ |12.0SZ|Early Deployment |Migrate to 12.0(23)S3 | |------+-----------------+-----------------------------------------------+ |12.0T |Early Deployment |12.0(7)T3** | | | |------+-----------------+-------------+-------+-------------------------+ | |85xx ls1010 | | |12.0(26)W5(28) | | |-----------------+-------------+-------+-------------------------+ | |c5atm |12.0(24)W5 | | | | | |(26a) | | | | |-----------------+-------------+-------+-------------------------+ | |Cat4232 and |12.0(25)W5 | | | | |Cat2948G-L3 |(27) | | | |12.0W5|-----------------+-------------+-------+-------------------------+ | |C6MSM,C5rsfc, |Engineering | | | | |C5rsm, |Special | | | | | |available on | | | | | |request | | | | |-----------------+-------------+-------+-------------------------+ | |C3620, C3640, | | | | | |C4500, C7200, RSP| | | | |------+-----------------+-------------+-------+-------------------------+ |12.0WC|Early deployment |12.0(05)WC8 | | | | |2900XL-LRE,2900XL| | | | | |/3500XL; 2950 | | | | | |release | | | | |------+-----------------+-------------+-------+-------------------------+ |12.0WT|Early deployment |Engineering | | | | |Catalyst |Special | | | | |switches: |Available | | | | |cat4840g, |upon request | | | |------+-----------------+-----------------------------------------------+ |12.0X |Shortlived Early |All 12.0X(any letter) releases have migrated to| |(l) |Deployment |either 12.0T or 12.1 unless otherwise | | |Releases |documented in the X release technical notes | | | |pertaining to the specific release.

Please contact the Cisco TAC and request the specific images you need posted. Obtaining Fixed Software ======================== Customers with contracts should obtain upgraded software free of charge through their regular update channels. For most customers, this means that upgrades should be obtained through the Software Center on the Cisco worldwide website at http://www.cisco.com/tacpage/sw-center/sw-ios.html. Customers whose Cisco products are provided or maintained through prior or existing agreement with third-party support organizations such as Cisco Partners, authorized resellers, or service providers should contact that support organization for assistance with obtaining the free software upgrade(s). Customers who purchase direct from Cisco but who do not hold a Cisco service contract and customers who purchase through third-party vendors but are unsuccessful at obtaining fixed software through their point of sale should get their upgrades by contacting the Cisco Technical Assistance Center (TAC). TAC contacts are as follows. * +1 800 553 2447 (toll free from within North America) * +1 408 526 7209 (toll call from anywhere in the world) * e-mail: tac(a)cisco.com Please have your product serial number available and give the URL of this notice as evidence of your entitlement to a free upgrade. Free upgrades for non-contract customers must be requested through the TAC. Please do not contact either "psirt(a)cisco.com" or "security-alert(a)cisco.com" for software upgrades. See http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml for additional TAC contact information, including special localized telephone numbers, instructions, and e-mail addresses for use in various languages. Workarounds =========== AFTER APPLYING THE WORKAROUND the input queue depth may be raised with the hold-queue <new value> in interface command -- the default size is 75. This will allow traffic flow on the interface until the device can be reloaded. Cisco recommends that all IOS devices which process IPv4 packets be configured to block traffic directed to the router from any unauthorized source with the use of Access Control Lists (ACLs). This can be done at multiple locations, and it is recommended that you review all methods and use the combination which fits your network best. Legitimate traffic is defined as management protocols such as telnet, snmp or ssh, and configured routing protocols from explicitly allowed peers. All other traffic destined to the device should be blocked at the input interface. Traffic entering the network should also be carefully evaluated and filtered at the network edge if destined to an infrastructure device. Although network service providers must often allow unknown traffic to transit their network, it is not necessary to allow that same traffic destined to their network infrastructure. Several white papers have been written to assist in deploying these recommended security best practices. ACLs can have performance impact on certain platforms, so care should be taken when applying the recommended workarounds. Receive ACLs For distributed platforms, receive path access lists may be an option starting in Cisco IOS software versions 12.0(21)S2 for the c12000 and 12.0 (24)S for the c7500. The receive access lists protect the device from harmful traffic before the traffic can impact the route processor. The CPU load is distributed to the line card processors and helps mitigate load on the main route processor. The white paper entitled "GSR: Receive Access Control Lists" will help you identify and allow legitimate traffic to your device and deny all unwanted packets: http://www.cisco.com/warp/customer/707/racl.html Infrastructure ACLs Although it is often difficult to block traffic transiting your network, it is possible to identify traffic which should never be allowed to target your infrastructure devices and block that traffic at the border of your network. The white paper entitled "GSR: Receive Access Control Lists" presents guidelines and recommended deployment techniques for infrastructure protection ACLs: http://www.cisco.com/warp/customer/707/iacl.html Transit ACLs The two techniques described above protect infrastructure devices. This IP protocol ACL can also be used to filter transit traffic passing through a network. The ACL will need to permit all protocols used by end users, not just those destined to routers. Since end users can run a wide array of protocols, often unexpected or uncommon protocols, these protocol requirements must be well understood prior to deploying this ACL. The provided list is not a complete list of permissible protocols. This access-list is applied inbound on edge facing interfaces. For complete protection this access-list needs to be implemented on the edge router. For basic TCP,UDP and ICMP, the following ACL will provide protection: access-list 101 permit tcp any any access-list 101 permit udp any any !! GRE tunnel if required access-list 101 permit gre any any !! IPSec ESP if required access-list 101 permit esp any any !! IPSec AH if required access-list 101 permit ah any any access-list 101 permit icmp any any access-list 101 deny ip any any The last statement of the Transit ACL should be a deny any any for IP traffic. Prior to deploying ACLs that filter transit traffic, a classification ACL can be used to help identify required permit statements. A classification ACL is an ACL that permits a series of protocols. Displaying access-list entry hit counters helps determine required protocols: entries with zero packets counted are likely not required. Classification access-lists are detailed in the above link for infrastructure access-lists. Exploitation and Public Announcements ===================================== The Cisco PSIRT is not aware of any public announcements or malicious use of the vulnerabilities described in this advisory. If PSIRT becomes aware of any sign of public announcement of the crafted packet, or there is any sign of exploitation of this vulnerability, a follow-up announcement will be sent to our standard distribution list immediately with further details to assist network administrators in mitigation.

by Geoff Cant 16 Jul '03

16 Jul '03

Hi there, I'd like to thank the organisers and all the nznog people who attended NetForum2003 for being really interesting and friendly - I had a great time. Despite being one of the few students there (I was from Massey PN) everyone was amiable and great to talk to. I'd especially like to thank Joe Abbley for his immensely interesting and funny BGP presentations, and Barry Greene and Evi Nemeth for their informative (and scary - 98% rubbish at root-servers) sessions. Thanks very much guys, much looking forward to NetForum 2004 -- Geoff Cant <geoffrey.cant.1(a)uni.massey.ac.nz> (I hope the above didn't sound too gushy, but I really did have a great time :)

RE: [nznog] IPv6
by Chris Hellberg 15 Jul '03

15 Jul '03

when I was running the v6ix in Wellington I was running EBGP sessions with most people who had connections; seemed to work well when I had a bunch of open-souce software mirrors which were v6-accessible and people had routes that went straight to the IX. There was also tunnel to the 6bone at Merit, for those who wanted to have a nosey at the 6bone routing table, although there were some 2000::/24 prefixes on the 6bone. I've talked to Si at Citylink about getting a PI peering block for WIX and APE, but it wasn't a huge priority. I used addresses from a freenet allocation and carved up a /64 in to a bunch of /126s and used them as point-to-point links. Not the best solution in the world, but worked for the purpose. -----Original Message----- From: perry(a)deeper.co.nz [mailto:perry(a)deeper.co.nz] Sent: Wednesday, 16 July 2003 21:43 To: Joe Abley Cc: nznog(a)list.waikato.ac.nz Subject: Re: [nznog] IPv6 -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 > You can't plumb tunnels right now, today? Or is the problem that > there's just no local place to plumb a tunnel to? > > (see http://ipv6tb.he.net/ for a tunnel broker run by clueful people in > the US). ahh, but tunnels to the US mean that you have the irritating problem that pinging someone on the same ISP as you can give you up to 3,000ms of latency as it transits from here to the US and back again. You have issues when they are overloaded, or down. You have issues if the internet between here and there decides that packets should be routed via darkest peru. IPv6 was designed to work in the situation where you have to bridge large IPv4 clouds. A much better solution for people in New Zealand is to use 6to4 addressing, especially if you're on the end of ADSL or similar and don't have native transport. 6to4 addressing means that whatever device(s) have non-RFC1918 IPv4 addresses can have a /48 assigned to them. 2003:<high two octets of IPv4 address>:<low two octets of IPv4 address>::/48. To route to another 2002::/16 address over IPv4 you just take the packet, encapsulate it in IPv4, and send it to the embedded IPv4 address. Linux and FreeBSD both support this. Latency to other 6to4 addresses is about the same as IPv4, avoiding the entire US round trip. To talk from a 6to4 address to a non-6to4 IPv6 address you route via ::192.88.99.1 which is an AnyCast address. Unfortunately, last time I looked the nearest 192.88.99.1 AnyCast announcement appeared to be in Germany. Is there any chance of someone putting forward 6to4 anycast gateway in the APE and/or the WIX? Of course the problem here is that probably 50% of it's traffic will be international. In an unrelated note, the MetaNet has been used by several people in NZ who are interested in playing around with more interesting networks without breaking things that people pay to use. We use it for peering IPv6 without having to go via the US and we'd be interested in organising IPv6 tunnels with like minded people (either using wand, gre, or 6in4 tunnels) Unfortunately the MetaNet wouldn't handle multicast very well (or we'd be having a good tinker with it) Resources: * http://www.wlug.org.nz/DancingPenguin (A IPv6 enabled website in New Zealand which is useful for testing with) * http://www.wlug.org.nz/IPv6LessonsLearnt (For some random things we've discovered about IPv6 the hard way, so you don't have to) * http://www.wlug.org.nz/6to4 (Information about 6to4 under Linux) * http://www.wlug.org.nz/IPv6 (Information about IPv6 on the wiki) * http://www.nevada.net.nz/~pmurray/6to4.html (6to4 under FreeBSD) If you want to chat about it, we're usually hanging around in #wlug on Undernet. irc://undernet/%23wlug - -- <f00Dave> Look, rejects, this is #OpenGL, not #GEEKSEX. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.2 (GNU/Linux) Comment: Only when you are sure they have you, can you stop being paranoid iD8DBQE/FQ0TcAgRpy8z8UQRAhadAJ4gAGn+YRABqt6A7X58K73hBQPNugCgy3ie 05qO9xRxAXyaG1K5EElVfAY= =+lkH -----END PGP SIGNATURE----- _______________________________________________ Nznog mailing list Nznog(a)list.waikato.ac.nz http://list.waikato.ac.nz/mailman/listinfo/nznog ------------------------------------------------------------------------------ "This communication, including any attachments, is confidential.

New Zealand regulatory bodies are trying to put us more in line with the US FCC standards. So I should not see to much of a problem,. 5.8 & 5.3ghz are virtually self managed by users as it is.

Although the 802.16a stuff is pricey at the moment (they're talking US$1,000 for customer "modems") it could be very interesting for providers looking to bypass the local loop stranglehold. Not just for the rurals, in other words. Here's hoping someone else than Walkers will try to deploy in Auckland. I wonder if there are any radio frequency spectrum issues here though? Redline's AN-50 looks like it delivers the same performance -- 72Mbps, up to 80km range... only 49Mbps "at the Ethernet level" though. -- Juha Saarinen

Hi Roger, Just a quick word of thanks for a most enjoyable couple of days in Auckland during the NetForum conference. Please pass on my thanks to Sue and all the others who worked hard to make it happen this year. I would also like to thank all those who contributed their time by giving presentations during the Thursday and Friday I was there. I didn't catch all the presentations, but the ones I did see were great. BTW, on the flight back to Wellington, I attempted to get into the cockpit and show the pilot what I had learned from the Flight Sim. presentation, but was promptly refused :) Thanks again, Tim DISCLAIMER: The content of this email is confidential and may contain legally privileged information intended only for the individual or entity named above.

ISC F root nameserver node live at APE
by Joe Abley 11 Jul '03

11 Jul '03

APE Peering People, Internet Software Consortium has a node of the F root nameserver at the APE in Auckland. Networks connected to the APE can gain access to this node by peering with it across the exchange, as follows: APE addresses: 192.203.154.98, 192.203.154.99 AS number: 23710 NOC phone: +1 650 423 1310 INOC DBA: 3557 NOC e-mail: noc(a)isc.org The APE path to F will also be available through the APE route servers. Networks peering locally with F gain lower transport latency and increased path diversity to the F root nameserver, which helps make the DNS as a whole more reliable. ISC operates an open peering policy. To set up a session please send e-mail to peering(a)isc.org. The F root nameserver node in Auckland advertises the single prefix 192.5.5.0/24 to peers which covers the address of f.root-servers.net. For further details of the general routing policy for F, together with a summary of remote F-root nodes deployed at other exchange points, see: http://www.isc.org/peering/ A representation of the policy for the F-Root node in Auckland is present in the IRR. The Auckland F root nameserver node was made possible by Juniper Networks, TelstraClear, FX Networks and 2day.com. Joe

legal threats from DE Technologies re web commerce
by Robert Hunt 09 Jul '03

09 Jul '03

James & Wells NZ Barristers and Solicitors (http://www.jaws.co.nz) are acting for DE Technologies ( http://www.detechnologies.com ) DE Technologies are described at http://www.globetechnology.com/servlet/GAMArticleHTMLTemplate?tf=globetechn… as "a tiny company in Montreal" and the patent as "a computer implemented process for carrying out an international commercial transaction." I hope this is not seen as off topic. I am at a loss to say whether this is an absurdity or a significant worry, but my firm has recently received a legal fax from James & Wells claiming we are infringing DE Technologies recently acquired NZ Patent. In what looks like a mass produced demand they appear to require that we "discuss" obtaining a license for three years for US $25,000 plus 1.15% of our and our customers' transactions, if we wish to continue hosting web sites that take international orders. The NZ version of the patent was obtained earlier this year. Curiously the target of their attention happens to be a website of ours that does not do actual orders itself but is just a portal, hence my guess that this is part of an broad initial salvo in an attempt to create the "pay up and avoid litigation" response. I want to make contact with other operations who have received a license and royalty demand under NZ Patent 505284 for large sums of money if they wish to continue using basic international web shopping practices. We can probably deflect the particular letter we have received, however if the barristers involved are keen to search out sites that do have some chance of coming under the patent then they should find a virtual cornucopia, as they traverse the sites of your customers and ours. Supposing they succeed in upholding their patent then their requirements would claim a significant percentage of overheads of net traders looking to continue having international ordering/transaction capabilities. Obviously I am sorely disappointed that the NZ Patent Office is granting patents of this kind, and am reviewing both political and legal options for raising this issue in the public eye. Alongside Microsoft's moves to patent .Net APIs we are of course, seeing some serious challenges to developer freedoms, and end user's integration choices, if the arena of intellectual patents is not balanced with concern for open standards in at least some of the world. Well that is off topic now I am sure... I am happy to set up a list for discussing this issue if anyone else is interested, let me know or point me to a pre-existing nz list on this matter. Oh and I'll let you know when I have a patent on the process of running an online charity auction to save ISPs sued by patent attorney's.. :) regards Robert -- Robert Hunt phone +64-3-3645888 Managing Director fax +64-3-3645828 Plain Communications roberth(a)plain.co.nz

Which brings me back to where I started -- with a bit of relaxation of the "I must see it NOW" requirement (in the order of a few seconds/minutes) and good client software/hardware, you can turn a bunch of not-quite-synchronous viewings into synchronous events. And thus snatch a multicast win, out of the jaws of a watch-now unicast defeat. This is both with "live" things -- which I agree aren't that common -- and also "near release time" viewings of things which aren't live (where you can expect that something which is recently released, and popular, is most likely to be wanted nearer the release time than later, in some sort of half-bell-curve type model). >Its just as the size of "live" viewer base gets smaller, and bandwidth >higher, multicasting doesn't seem worth the effort. Well I've seen approximately three orders of magnitude (powers of 10) drop in the cost of bandwidth/traffic over the last 10 years or so, and it's still at least two to three orders of magnitude away from the point where I'd be willing to say the "cost" of getting multicasting going isn't worth the value of the saved bandwidth. Generally like RAM space, harddrive space, etc, the uses will expand to fill all the available bandwidth, so using it inefficiently isn't exactly desireable. >If I stream an event for say 10 viewers, why should the rest of the >NZ net get it sent to them without asking for it. Umm, that's not how multicasting works (indeed it's the key difference between multicasting and broadcasting). But I think you know that already. Ewen

Apparently at least one spammer actually claimed to have used Mark's changes list as a source, which is presumably why the interium action was to ask for it to be taken down. As Steven Heath noted, there is a mention in the June Registrar newsletter; and it will be in the minutes from the June NZOC meeting which should be up RSN I'm told (apparently they were overlooked for a while in amongst everything else going on and now just need to be reviewed by NZOC for accuracy). And there should be some sort of call-for-comments coming out relatively soon (sometime in July?). >Is it doing any harm or is it because it isn't published by DNC and so >not sanctioned? Actually as I remember it Mark's site was one of the few that made it onto the original blessed list of those who could still do zone transfers when restrictions were put in place (a couple of years back). AFAICT it's merely the "source of addresses for spam" problem which makes it an issue, rather than "not run by the DNC". Ewen

RE: [nznog] Multicast status in New Zealand
by Michael Sutton 08 Jul '03

Point of Technical peturbance Multicast is much more efficient. The data does not flood to every router in New Zealand. Actual data, just like unicast, only routes to those branches of the network where there is actual demand at that instance in time. If there is no downstream client application (player) requesting the data feed, no data will be sent to that location. The only data held by routers is information about the identity of the upstream multicast source, if there is client request. If the demand was only in Wellington the multicast data would not leave Wellington. When someone joins in Auckland then the data would flow to Auckland and no-where-else... When the Auckland users ceases the session data transfer would be pruned back to Wellington while the multicast session continues.

RE: [nznog] Multicast status in New Zealand

I agree with your take on the issue, Ewen... Further, it is surely in the "National Interest" that multicast be in active operational capability today for the "Public Internet" so that in the event of a future national crisis such as a SARS, Foot and Mouth, Small Pox or when a similar situation occurs the facility can be used to its best technical advantage. It is then important to: communicate, instruct & train, professionals and the public - while reducing close personnel contact. Multicast can be used to provide "low cost" high quality content injection which of itself does not cause degradation of New Zealand network performance at any location during a strategic performance window. Alternatives such as Consumer Digital Satellite TV would cost, at list prices, significant dollars to open up spot channels for a period of days || weeks || months, and in such circumstances the Ministries available discretionary funds would be under severe pressure, and therefore may be excluded as a viable option. However, multicast would help, as the cost of 48hours digital satellite television broadcast might equate to the cost of one years multicast distribution @ 300kbs. During the SARs containment emergency, Beijing and other locations in China closed schools and other education institutions and made children stay home. Their schools used telephones and the Public Internet to conduct distance learning. What would happen in New Zealand if all schools in Auckland and other city locations closed. Multicast was also used to connect SARS support hubs in Asia. Therefore prior to such an emergency, operational multicast services today would enable strategic content provider organisations to distribute current operational materials for capture and/or real-time display and be prepared and confident that such a system can be relied on as a front-line communication capability. So... reliable operation today ensures access when Noah needs an Ark... Nobody will try to implement it the day a Balloon goes UP... Hope you are all having a great conference... Is Joe warbling now...

The problem, IMHO, is not the broadcasting, or the channels, themselves. It's how people make use of them. Broadcasting is a fairly efficient technique to get information to a whole bunch of people in one go (for them to use now or later). Channels are an efficient way to know which broadcast to listen to for what things. I simply don't buy the argument that says that because the "must watch it when it screens, must watch what they want to show" model of broadcast channels is bad (which I definitely agree with -- I haven't even had a TV for 5+ years), that means that all the components of it (broadcasting, channels, etc) are totally without merit. To get, vaguely, back on topic -- multicasting is just "broadcasting with focus" -- if you like it's a more efficient form of broadcasting for a medium which can handle sending only to interested parties (eg, a packet switched network like the Internet, as opposed to a frequency division "network" like radio waves). >[Spoonfeeding, etc] >This is what makes me leery of attempts to make the Internet a better >broadcast medium than it already isn't.

I don't recall suggesting that you should. >Hey you have 10 minutes now and would like to catch up with what he said last >Monday (when you were on the phone, remember). So why can't you click in >now and view it ? Your argument seems to be "viewers must be able to view it __NOW__(tm)" and hence we must use unicast for everything in order that everyone can have their whim satisifed at an instants notice (and provide all the bandwidth from source to (multiple) sink(s) to make this possible). My argument is that there's a fair chunk of evidence that says that people would be willing to wait 1, 2, 5, 10, 30, or even 60 seconds for something to start (maybe even longer if it's a sizeable time investment to watch it all and the waiting time can be used productively -- eg, getting that beer out of the fridge before settling down to watch the game), especially given a proper cost/benefit tradeoff ("would you pay 5 times as much to be able to have it start within half a second instead of within 5 seconds"?). And that by adding that relaxing condition it's both quite feasible, and quite benefical, to use multicast at least for the more popular things, especially where the multicast VDCs is set up "on demand" with just a short "setup time" to pull in other potential viewers. Think of it as the difference between everyone just crossing the road when they feel like it, and traffic lights (or at very least waiting for the same gap in the traffic). The big reason that it's beneficial in the popular-to-(re)view situation is that there're more people wanting to view something than there are 5-second, 10-second, 30-second, 60-second, whatever start periods. So you can achieve an N:M reduction in the number of VDC you need originating from the source, for only the price of a bit of management infrastructure (request-a-start-soon), and a slightly slip from the "I wanna watch it now! Now! Now! Mommy, make it go!" instant satisfaction. >Multicast is great for synchronous events like TRADITIONAL tv. I just don't >see that continuing. It's good for things other than traditional TV too. Especially where there's (significantly) more than one person wanting to watch something at the "same" time. Which is a surprisingly common case for "current" events. (Speech replays, sports replays, recent movie releases, etc.) Oh, and I quite agree with Joe's comment that caching at the edge can achieve quite remarkable things in turning "watch now or miss it" into "watch when you feel like it". (And even better, if those with suitable broadcast channels would actually get a clue and use the "down" time to spool out things people might want to watch during the week (eg, "this week's hot new movies"). But "video recorders are bad, we must do everything to defeat the use of video recorders". Furrfu.) Ewen

You can probably get around it using the argument that subsection (2) makes any access at all legal as long as you were given permission to do something first; "(1) Every one is liable to imprisonment for a term not exceeding 2 years who intentionally accesses, directly or indirectly, any computer system without authorisation, knowing that he or she is not authorised to access that computer system, or being reckless as to whether or not he or she is authorised to access that computer system.

Chris The setup of the Multicast Network Border Peering is not hard. The content provider who injects the multicast is protected from unicast server cost overruns, while client customers pay for all their bandwidth and data received. If the tariff is based on bytes then multicast would generate ISP revenue for the network that delivers it to the client. In so far as content providers using multicast: As someone who has concurrently delivered live Radio New Zealand BBC World, XtraMsn Music Channels as well as Compaq || Hewlett Packard and Ministry of Health Live events, all of these content streams, where possible, used dial-in multicast for the Xtra network and would have used multicast via adsl for all events if possible.

Abuse desk responses
by Steve Phillips 07 Jul '03

07 Jul '03

Has anyone else here had problems with NZ ISP abuse complaint responses ? mainly in response to SPAM reports where they refuse to do anything until they get blacklisted but also covering network abuse (DOS type scenario's and the like) ? It appears that abuse complains are more and more regularly falling on deaf ears where the person/team handling the abuse desk seems more concerned with pointing out how it is not their problem than actually trying to educate their end users as to correct practices. This does not appear to be restricted to smaller ISP's either as the main offender (though not limited to) in this case appears to be paradise. -- Steve.

Voting closes on the 14th July. I am standing as a Candidate for Councillor on a platform to encourage IP4 multicast peering and service to users of the public Internet in New Zealand. There is significant effort within InternetNZ to encourage NGI and IP6, however, this can not provide immediate public access to multicast services. If elected I will make every effort to encourage implementation of multicast services via public networks.

Who is the NZOC? NZOC == New Zealand (DNS) Oversight Committee, which is the committee in InternetNZ which "oversees" the Domain Name Commissioner's office. I wasn't aware that they were (still) conducting a review (again), and Mark's "changes" list seems (at first glance) to be consistent with the existing zone transfer policies. I know that Mark updated those scripts recently ('cause I prompted him to do so, since some links were out of date including the ones for whois) -- maybe it just picked up a copy of a "in progress" version of the script generating the changes file? >I guess lots of people doing the same thing would be bad, but this page has >been around for yonks. As I understand it, that was the main reason (in an earlier interation of setting zone transfer restrictions) for allowing Mark's scripts to keep going -- it was one point where people could look for changes, rather than everyone doing their own zone transfers.

Conference Attendance
by Simon Lyall 06 Jul '03

06 Jul '03

A quick question but are the sessions being recorded and available for later download? I've noticed a couple of sessions I'm interested in opposite each other and also had queries from people at ihug not attending (who said they like watching nanog recorded sessions). I got feedback from a couple of people (one attending, one not) after my requested on Thursday. Both said that the conference is "mainly being a chance to sit in a room with other engineers and sort out new fun stuff." The one who wasn't going said there wern't enough sessions they were interested in (or more directly related to their work) to convince their boss to let them have time off and/or pay for them. "So what would work consider worthwhile? More bleeding edge technology stuff, new product things, more seriously detailed technology discussions (eg a panel about QoS and the various algorithms used and why, might be something that'd attract the Telco types).

Net4U Thread
by Donald Neal 03 Jul '03

03 Jul '03

The current (or immediately past?) thread dealing with Net4U contains some postings which are clearly within this list's acceptable use policy, and some which are not. In brief, postings which discuss operational or technical issues - and an ISP using spam to advertise does look to me like one of those - are in. Postings containing "character assassination or lack of respect for other participants" are out. Whether they cause deformation or not. For myself, I'd like to see no further additions to the thread unless they come from people who have something new and relevant to say. - Donald Neal ex cathedra, or something Donald Neal | Doctor: Did you see what I didn't see?

Sahil said to me, as well as publically on the site that the "auditor's" report would be made available publically on the website. After a number of months I saw him again, and casually asked, whats up with that auditor's report, and he shrugged it off, as if to say "that was a joke". Secondly Sahil obviously did know about it, so shrugging it off as his staff's fault is amusing in the least

19" Cases.....
by Roger De Salis 03 Jul '03

03 Jul '03

I have built two self assembly 19" cases, simply designed to be a simple as possible, and extremely low cost. Unit One, 2.5RU (ie the same height as a standard PCI card.) 450mm deep. Accepts standard power supply, any ATX board (full, mini, micro). Combos are Std CDROM + Floppy + 6 drives OR up to 10 disk drives without CDROM/Floppy Assembly. No risers. One case fan (included). Unit Two, Same Height as standard ATX power supply 90mm, 2RU, 275mm deep. Accepts micro ATX board only. Accepts Standard ATX power supply. Accepts laptop 1/3high floppy and CDROM (which I can supply if required) $169 for CD, $79 for floppy. Accepts 1/2 high PCI Cards only. No risers Unit Two currently supports 1 x 3.5" DD and 3 x 2.5"DD. Production version will likely be modded to accept 2 x 3.5"DD and 2 x 2.5" DD ========================================================== Removable 19" Rack wings on both. Mounting combinations are: Flush front, recess 50mm, centre pillar mount, or reverse mount, and 50mm recessed reversed. The intention is to place a full shelf underneath the base unit, then I would not have any qualms about 4-5 racked up on top of each other. There is currently no provision for slides, but if someone was desperate..... Henry Ford Colour scheme. NZ$260+GST complete with PSU, wiring assembly pwr/hdd assy, screws. Netforum Special NZ$230+GST. I'll have three units on show at the Waipuna next week if someone wants to look/dicuss. The second small unit was intended to complement Cisco 2600 in a rack, but also be the right size for home stereo with silent PSU and 2.5"DDs, so if you want to buy your own power supply, knock $35 off the price. Further discounts for quantity (ie 4up.) If you want to buy just the metalwork, and make up your own, happy to oblige... Basically I run them as telephone controllers, log servers etc etc, with a Duron 1300, MSI 6787 board with LAN on-board, single drive and CD for approx $700, rack mounted with a 2 year warranty on everything. About 14 day delivery. I'll include a couple of JPEG's later this morning.

Net4U's earlier actions
by Sahil Gupta - NET4U LIMITED 02 Jul '03

02 Jul '03

Hi, Firstly, I'd like to apologise for actions made earlier during the day with respect to a mailout to a certain group of ISP's. I wasnt thinking clearly when I thought to add a few more addresses to the mailout to existing contacts. My bad, wont be repeated. As Richard has suggested, if anyone has any concerns or issues that need addressing, please contact us off-list. Just for those that were concerned, issues with abuse(a)net4u.co.nz have now been resolved. Once again, my apologies for the drama here in NZNOG.

You have some valid points here. The whole thing is quite disappointing, and for many, quite frustrating. This abuse(a)net4u is also becoming a sore point, and clearly there has been an issue with this address. I can only chase up as much as was passed on to me. There are a number of other recommended tasks which were to be carried out but have not :( Please contact me off-list with more details, and I will be happy to deal with things. As I said, I'm sill helping Net4U (Unpaid I might add) here and there when I am not involved with my regular clients. If anyone else is reading this and has ANY issues with Net4U that have been ignored, please feel free to contact me off-list or directly on 021409987, and I will to my best to deal with things. This is not the place for this nonsense, so lets get all this off-list, contact me, and lets get everyone happy. If no one has any other abuse they want to throw this way, perhaps we can move back to other interesting threads such as Multicast which I enjoyed following? How about why ISP's should/shouldn't be able to control assignment of IP addresses on ADSL Starter? Anyone have any views on this? Cheers, Richard. -----Original Message----- From: Dave Howes [mailto:mish(a)doomx.net] Sent: Thursday, 3 July 2003 6:49 p.m. To: nznog(a)list.waikato.ac.nz Subject: Re: [nznog] APE Peering I think we should all take a good look at ourselves, and the motivation behind the pettiness that from time to time, makes me wonder just how many children play on this list, and how many people are here to get work/business done. Lets just get on with our work please everyone. Each time the topic of Net4u has come up I've resisted posting as previously the entire situation was already at boiling point, but suggesting people are here to play when they're obviously just frustrated by actions that they see as detremental and disrespectful to other New Zealand Network Operators really rubs me the wrong way. Net4u does seem to be operating in a more legal fashion than before but they're still not admin friendly by any stretch of the imagination. I've received spam from net4u customers to domains I previously managed, I contacted Net4u to advise them of this ( abuse(a)net4u.co.nz) but have never received any response. I was also informed of a 'hole' in their security through which anyone can log into the net4u network and gain free ADSL service by use of an 'admin' account, I emailed the administrator of net4u to advise of this but despite sending two emails I never received a response and (I just tested) the hole still seems to be wide open. I'm glad you see the spam from Net4u as a bad thing as even though the operators of Net4u are (reasonably) new to the game, in this 'net enabled' age even the newest player has no excuse for thinking that unsolicited commercial email to a soa address is a good idea, the same goes for their previous dubious actions. You can feel free to view comments like these as 'pettiness' but I for one am glad to be informed of the actions (or inaction) of New Zealand ISPs even if the observations are at times coloured by external factors. -- Regards, Dave Howes.

LOL - Tis so odd.....
by Michael Hallager 02 Jul '03

02 Jul '03

Richard's entire post looks clearly like a Sahil marketing effort: COPY We have made a brief report which is not for public viewing, but which has identified a small number of issues on the Net4U network (which were quickly rectified) that were as a result of previous employees. We found nothing that was causing deliberate loss of bandwidth to any other party. We did not fully complete the work due to budget restraints, however we did cover most of the important aspects. Some of our recommendations have been implemented, and sadly others have not been done, but Net4U are operating somewhat better than they were. /COPY YEAH RIGHT. We all have the MP3 of Sahil BOASTING about taking bandwidth. How do you reconcile that with your above claim? I think we would all like the answer. Sahil also ropes his friends into fronting for him, including doing the following actions, both people have admitted that Sahil got them to contact me: 1) Sending me an abusive email 2) Contacting me to rent several thousand dollars worth of equipment that I would never loan to Sahil. COPY > I can assure you the bandwidth offered by Net4U in that "distributed" > email is legitimate, and I should warn you that continued accusations > and alligations are a direct attack against me and my company, which > left Net4U operating legally and above board, and there is no > justification for this blatant deformation. /COPY Don't like the heat, get out of the fire. You knew full well what you were getting into when you associated yourself with Net4u by doing this contracting job. COPY It doesn't take much for everyone to see that some of you are making an issue simply because it's Sahil and Net4U, and because you were a reject at school who was picked on and bullied, and now have a psychological disorder resulting in you playing out the role of your boyhood deamon from school, dishing out what you received. /COPY OK, whatever. I have a small **** or a demon or whatever (This is starting to sound like whacky religious stuff). How did you KNOW??? Michael Hallager Managing Director Networkstuff / Comsolve
