Federal plans for Internet simulation and assessment
by Fred Heutte 04 Dec '01

04 Dec '01

Declan McCullogh has a number of interesting references in his current Politech note. Excerpts are shown below. The concern for improved security and resilience is commendable, the immediate focus on vendors cramming down patches on users is, erm, debatable. http://www.politechbot.com/p-02875.html -------- As part of its efforts to beef up homeland security, the federal government will set up a national center for infrastructure simulation and analysis in January, said Richard Clarke, chairman of President Bush (news - web sites)'s Critical Infrastructure Protection Board. ``The center will create, if you will, an acupuncture map of the country, so that if there is a fire in a railroad tunnel in Baltimore, we know the Internet slows down in Chicago,'' Clarke told a gathering of high-tech executives at the Business Software Alliance's first Global Tech Summit .. Clarke also appealed to the private sector, which controls the vast majority of the Internet's infrastructure, to beef up its security practices as well. ``We need to decide that IT security functionality will be built into what we do. It's not an afterthought anymore,'' he said. Software products should be shipped with security settings at their highest level, he said, and high-speed Internet providers should require individual users to install ''firewalls'' to protect against damaging viruses. Software companies should not just make ``patches'' available to fix vulnerabilities in their products, but automatically update users' software for them, he said. ``It's not beyond the wit of this industry to figure out a way of forcing down these patches,'' he said. http://dailynews.yahoo.com/h/nm/20011204/wr/tech_security_dc_1.html

RE: interesting CAR related crashes in 12.0(14)S

Are the GigE cards single port or 3 port. I jave had issues with packetloss on the 3 port GigE cards on my GSRs.

I understand the point of image/damage control, thought at this time what I am interested is not a reply from Cisco along the lines of "please send the 'sh tech'". Rather I am interested in hearing from people who are using GSRs in non-lab environments about similiar issues since I happen to have a hunch that should I not get that background information myself, I would have a problem convincing people that the issue had even been there... So, returning to my original question... Does anyone know of "interesting" crashes related to CAR on GSRs running IOS release close to what I have described... (Since during the past tests the same router in the same setup with the same IOS ran just fine when it was applying same type of rate-limiting to 3x as much traffic on a different sub-interface) Thanks, Alex > > Thanks, > rodney > > On Mon, Dec 03, 2001 at 07:00:05PM -0500, alex(a)yuriev.com wrote: > > > > > > Hello, > > Does anyone know of any "interesting" bugs that are triggered on > > GSRs with CAR active running 12.0(14)S, preferably S3?

Not at this time, unfortunately, but as plans proceed you can expect for peering to begin. -mark "The information transmitted is intended only for the person or entity to which it is addressed and may contain confidential and/or privileged material.

@home -> Charter will show up as: 22665, 22521, 19115, 19157, 22269, 22291, 20115, there might be a couple more as time goes by.

The Tables Have Turned For PSI And Peering

I think this is ironic, considering the history of what PSI has done to de-peer with multiple companies. ;-) Rachel > ---------- Forwarded message ---------- > Date: Mon, 03 Dec 2001 16:01:03 -0500 > From: Nikki Mashack <mashackn(a)psi.com> > Subject: peering > > Hello, > > > My name is Nikki Mashack and I'm with PSINet.

AT&T @Home customers - what AS are you moving into?
by dani-post＠roisman.com 03 Dec '01

03 Dec '01

For those of you who have had your connection switch from AT&T @Home to AT&T Broadband, would you mind providing a sample prefix (or at least destination AS) that you're now in? @home (AS6172) played a significant traffic role on my network, and I want to make sure I'm prepared for any potential shift as customers are moved off that backbone. Thanks, - Dani

I've had no problems, apparently some people are on AT&T @Home, while others are on AT&T Broadband, I am an AT&T Broadband customer, some of my friends (Atlanta, Seattle) are AT&T @Home customers who no longer have access, AT&T claims that everyone who lost access lastnight will be online with AT&T Broadband within ~10 days.
