Does anybody have any experience with how much bandwidth you can realistically route through a 2610 before it starts to huff and puff? ie, Will it cope with 2x 2meg frame ccts running flat out - PWM "Hell, there are no rules here - we're trying to accomplish something!"

The original poster is aware of how blocking ICMP breaks things.

I was actually trying to query (obviously not successfully - well Joe got it!) why the routing to one of the resolved addresses for www.nbnz.co.nz is being dropped by Xtra on their border router @ APE. Secondly why the hell the traffic should go through Australia to get their in the first place.

CLEAR Net Tempest
by Neil 16 Aug '01

16 Aug '01

Hi All, Has anyone else had any problems with Clear's 802.11 wireless internet service (http://www.clear.net.nz/services/tempest.html) as a source of interference? They have just done a rollout in Rotorua and totally stoped 3 separate wireless networks that had been running together nicely for the past year or two. Clear have told me that Rotorua is the only place that this has happened in and are being very slow to do anything about it so if this has happened to you could you let me know.

Cisco pages about code Red.
by Roger De Salis 16 Aug '01

16 Aug '01

Apologies if you have seen this multiple times. It is a little more complete than previous posted items. - R Cisco Technical Assistance Center News Flash - August 16, 2001 http://www.cisco.com/tac -------------------------------------------- "Code Red" Worm Update ____________________________________________ Dear Cisco Customer, For the most up-to-date information on the "Code Red" worm, visit the Cisco TAC Web Site "'Code Red' Technical Tips" page. Be sure to check this page for new and updated documents. The "'Code Red' Technical Tips" page can be reached at: http://www.cisco.com/tac/newsflash/codered_tt_08162001.html ISSUES REGARDING THE "CODE RED" WORM There are three main issues to deal with regarding the "Code Red" worm: 1. The worm infects and replicates through a vulnerability in the Microsoft Internet Information Server (IIS). This creates an infection exposure for Cisco products that embed or run on IIS. This exposure can be dealt with by applying Microsoft patches to the IIS servers. These patches are available at: http://www.microsoft.com/technet/treeview/default.asp?url=/technet/security… 2. The earlier versions of the worm launched Denial of Service (DoS) attacks from the infected servers targeted at the White House Web Site. These DoS attacks can create high volumes of Internet-bound traffic. 3. The most recent variant of the worm creates high volumes of traffic on local networks, which may disrupt general network performance. The majority of the calls the Cisco TAC is receiving from customers are not due to Cisco products being infected by the worm; rather, many customers are experiencing the indirect impact that is caused by the messaging storms that occur because infected IIS servers are generating large amounts of network traffic while attempting to infect other IIS servers. This network traffic may cause networking equipment to become overloaded, which results in slow response, reloads, and other types of network equipment failures. Workarounds for the affected equipment, where applicable, are available at the "Cisco Security Advisory: 'Code Red' Worm" page, which can be found at: http://www.cisco.com/tac/newsflash/codered_secadvisory_08162001.html UNDERSTANDING THE "CODE RED" WORM A malicious self-replicating program known as the "Code Red" worm is targeted at systems running the Microsoft IIS. Several Cisco products are installed or provided on targeted systems. Additionally, the behavior of the worm can cause problems for other network devices. The following Cisco products are vulnerable to infection because they run affected versions of Microsoft IIS: * Cisco CallManager * Cisco Unity Server * Cisco uOne * Cisco ICS 7750 * Cisco Building Broadband Service Manager * Cisco IP/VC 3540 Application Server Other Cisco products may also be adversely affected by the "Code Red" worm. Please read "Cisco Security Advisory: 'Code Red' Worm" for further details. This advisory can be accessed at: http://www.cisco.com/tac/newsflash/codered_secadvisory_08162001.html All updates and workarounds are available under the "Featured Links" section of the Cisco TAC Web Home Page, which can be reached at: http://www.cisco.com/tac/newsflash/featured_links_08162001.html To access the documents directly, go to the "'Code Red' Technical Tips" page. This page can be reached at: http://www.cisco.com/tac/newsflash/codered_tt_08162001.html You can prevent the infection of servers and stop the spread of the worm by applying a Microsoft patch to vulnerable servers. This patch is available at: http://www.microsoft.com/technet/treeview/default.asp?url=/technet/security… Once infected, a system may require additional repair due to the damage caused by the worm. This is also documented on the Microsoft Web Site at: http://www.microsoft.com/technet/treeview/default.asp?url=/technet/itsoluti… ADDITIONAL RESOURCES The Cisco TAC Web Site "'Code Red' Technical Tips" page includes new and updated documents with details about how the worm virus impacts Cisco networks, and what you can do to protect your network. These additional resources include: * "Cisco Security Advisory: 'Code Red' Worm - Customer Impact" * "The Network-Based Application Recognition and Access Control Lists for Blocking the 'Code Red' Worm at Network Ingress Points" * "Dealing with 'mallocfail' and High CPU Utilization Resulting From the 'Code Red' Worm" * "How to Filter 'Code Red' on Cisco Cache and Content Engines" CISCO PRODUCT SECURITY INCIDENT PROCEDURES Complete information on reporting security vulnerabilities in Cisco products, obtaining assistance with security incidents, registering to receive security information from Cisco, and handling press inquiries regarding Cisco security notices is available at: http://www.cisco.com/tac/newsflash/prod_security_08162001.html Sincerely, Cisco TAC -- \_ Roger De Salis rdesalis(a)cisco.com </' Cisco Systems NZ Ltd +64 25 481 452 /) L8, ASB Tower, 2 Hunter St +64 4 496 9003 (/ Wellington, New Zealand roger(a)desalis.gen.nz ` By 2003, every home should have a Terabyte file server, a 10Mbps Internet Connection, a decent firewall and no M$ taxes. --------- To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog

early daylight saving
by Joe Abley 14 Aug '01

14 Aug '01

If daylight saving is brought forward this year, I guess we'd need a new 2001-only rule in the unix timezone database. The copy I have in my OpenBSD source tree says updates should get sent to tz(a)elsie.nci.nih.gov. Is there some standard government protocol for notifying changes in daylight-saving time to other relevant agencies, like IATA? Just interested :) Joe http://www.nzherald.co.nz/storydisplay.cfm?storyID=207726&thesection=news&t… Daylight saving idea to beat cuts 15.08.2001 By VERNON SMALL deputy political reporter An early start to daylight saving is possible if the electricity crisis deepens. The radical idea, coming as energy savings fall below the required 10 per cent, could cut power use by extending daylight into the evening peak time. A spokesman for Energy Minister Pete Hodgson said the minister had an open mind on the suggestion, put forward by one industry player. The proposal would be explored over the next two weeks, but Mr Hodgson would not say whose idea it was because the person had requested anonymity. A rough estimate by electricity market company M-Co showed an overall power reduction of 3.5 per cent in the first week of daylight saving last year. For the past three years, the reduction in the first week averaged 2 per cent. More important, in the first week of daylight saving, peak evening consumption, between 5 pm and 8 pm, dropped 7.5 per cent last year and an average of 5.5 per cent over the past three years. Peak morning demand, between 7 am and 9 am, fell by smaller amounts. "If you can keep it lighter later, the lights come on later and you save power," said M-Co's general manager of communications, Jane Tronson. Decreasing demand in peak times could also reduce potential price spikes. Act energy spokesman Gerry Eckhoff called for clocks to be put forward as early as September 1 rather than the due date of October 7. That would save power because people would eat dinner earlier and might use the barbecue instead of the electric stove, the MP said. "I guess if they sit down to dinner and watch the news at 5 pm instead of 6 pm it is still a wee bit warmer." Even a small amount of saving on lighting could accumulate across the country. There could be bigger savings in the North, where twilight lasts less time than in the South. But Federated Farmers energy spokesman Tom Lambie firmly rejected the suggestion. "We are in the busiest time of year in full flight with calving. The last thing people want to do is get up in the dark. The first daylight hours are precious for getting on with the job." A study in California, which has suffered rolling blackouts, found that daylight saving saved only small amounts of power but caused significant reductions in peak use. However, Mr Eckhoff said California had a big demand for power for air-conditioning rather than heating. The icy blast sweeping NZ from the south has caused another hiccup in the power-saving effort. Snowfalls and a cold southerly change meant savings dropped to 6.5 per cent on Monday. In the past seven days, average savings have been 9.4 per cent. However, M-Co admitted yesterday that the power saving figure published for Saturday was incorrect. The actual saving was 7.3 per cent, not 1.8 per cent as it reported. Meanwhile, one power company is trying to boost the everyone-pull-together power-saving message by offering yet another cash incentive - this time with a twist. Contact Energy, one of the four big electricity generators, which also has about 22 per cent of the retail market, will give up to $400,000 to worthy causes in regions where power consumption is cut by 10 per cent over the next month. Contact chief executive Stephen Barrett said regions must save at least 4 per cent to get any money. Those that missed the 10 per cent target but still made savings would be rewarded on a sliding scale. --------- To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog

Firewalling on Cisco router?
by PhoneNet 14 Aug '01

14 Aug '01

Can anyone give some suggestions on the best way to firewall a system using a Cisco router.... a friend on another list I'm on has been charged with moving a system .... some of the misfortunes he has been faced with so far are (Don't Laugh): 1.They had no list of thier machine names, 2. No IP addresses, 3. moved token ring to ethernet. 4. They had hubs, but no patch cables.... They get the Cisco router today and are moving tomorrow. Initally they will just use a very restrictive set of Cisco filters and NAT. It has bee nsuggested he use either Checkpoint or Cisco Pix, both standalone machines. Any comments?
