Sweet 16 for Morris Worm....
by Fergie (Paul Ferguson) 05 Nov '04

05 Nov '04

Just ran across a reminder that at around midnight on Nov. 2, 1988, the Morris worm was released. Happy belated 16th birthday. :-) - ferg -- "Fergie", a.k.a. Paul Ferguson Engineering Architecture for the Internet fergdawg(a)netzero.net or fergdawg(a)sbcglobal.net

BitTorrent is 35% of traffic ?
by Deepak Jain 05 Nov '04

05 Nov '04

http://in.tech.yahoo.com/041103/137/2ho4i.html According to Reuters, BT is more traffic than web/other forms of traffic? I'm thinking the sampling methodology here might be a little skewed. Then again, I could be biased. Any other facts that would support this? DJ

Light Reading: PIX Source Code For Sale
by frank＠dticonsulting.com 05 Nov '04

05 Nov '04

Black Market Offers Cisco's PIX [Firewall Source Code] NOVEMBER 05, 2004 Source code for Cisco Systems Inc.'s (Nasdaq: CSCO - message board) PIX firewall is up for sale. Too bad it's not Cisco doing the selling. An underground group known as the Source Code Collective is offering PIX version 6.3.1 for $24,000, according to a newsletter posted by the group to Usenet on Halloween. Little is known about SCC. The group debuted in July with an offer to sell source code from Enterasys Networks Inc.'s (NYSE: ETS - message board) Dragon Intrusion Defense System for $16,000 as well as Napster server and client source code for $10,000. Those prices have since gone up to $19,200 and $12,000, according to the recent newsletter. Those aren't the only companies in SCC's sights. The newsletter claims the group has virtual reams of source code to sell, but a full list is only available to previous buyers. "If you are requesting something from a Fortune 100 company, there is a good chance that we might already have it," the newsletter says. SCC even takes requests, supposedly assigning a team of hackers to retrieve source code for a price. The newsletters are posted by someone calling himself "Larry Hobbles" with an email address registered to a South African domain. SCC originally did its selling through a Web site registered to a Ukrainian domain -- they're a very cosmopolitan crew -- but had to drop that business model, citing concerns from customers. SCC now communicates with customers through email and Usenet only. To allay concerns of authenticity, SCC is willing to sell its code in chunks, allowing the customer to verify that the product appears genuine before purchasing the whole thing. The PIX sale is Cisco's second significant source-code scandal this year. In May, hackers claimed to have stolen the code for one version of the company's Internetwork Operating System (IOS) and posted part of the bounty on a Russian Web site. A British man was arrested in September, but few other details of the investigation have emerged. (See Cisco's IOS Code 'Compromised' and Cisco Code Hacker Arrested .)

RE: BitTorrent is 35% of traffic ?
by Matt Ryan 05 Nov '04

05 Nov '04

Cachelogic put appliances into the network that both monitor traffic (semi-deep packet inspection) and also cache P2P content to take the load of your network. While I don't think they made the figures up it's worth bearing in mind they are selling a 'solution' to the problem they highlight. For the record we have seen P2P traffic over 50% of our bandwidth utilisation - if bittorrent is the largest proportion then it could reach 35% of total bandwidth.

OT: looking for a contact at US .mil

I realize some may believe this is not of a very high priority, but I believe it is important. I apologize for going off-topic. There seems to be a network misconfiguration over at .mil which our intrusion detection systems caught. We are getting SNMP requests from them (their network is 147.238.0.0/16 and ours is 147.237.0.0/16. I suppose somebody probably typed a 7 where they should have typed an 8). I've done quite a bit to try and contact somebody over there - I even got somebody to talk to me on the phone in 4 distinct occasions and considering their whois information is outdated to the extreme - I am pretty proud. Yet the traffic continues. It doesn't really bother our network, but hey, this ain't right. I tried contacting them through some private contact as well.. but I figure that somebody over there who *cares* probably should see this raised flag. I appreciate your help, Gadi Evron.

Low latency forwarding failure detection
by John Kristoff 04 Nov '04

04 Nov '04

Not receiving any response for over a week after posting this query to cisco-nsp I thought perhaps folks here might have some input. In my scenario, Cisco is the likely gear involved, but even if people have vendor neutral feedback about this I'd be interesting in hearing it. From: John Kristoff <jtk(a)northwestern.edu> To: cisco-nsp(a)puck.nether.net Subject: Low latency forwarding failure detection Date: Tue, 26 Oct 2004 17:14:57 -0500 X-Mailer: Sylpheed-Claws 0.9.12 (GTK+ 1.2.10; i686-pc-linux-gnu) I've got a situation where something like HSRP seems appropriate for a redundant default gateway configuration. However, this application will want very low latency in finding and using the alternative gateway. Note, while the hosts have two NICs, they are both on the same subnet with one interface the default source and sink as long as it has link. I don't get to change this behavior. Default HSRP failure detection time however is likely not quick enough to bring a standby interface up to get traffic moving again. I see that HSRP provides for hello and hold times in milliseconds. I have a few questions for people who may have had a need to get very low latency recovery of links and routers. Have you used HSRP to do this? On a typical local ethernet (gig) LAN configuration, what sorts of latencies and packet loss have you seen during a failure event? I'm cco-familiar with GLBP. It appears to have essentially the same timing knobs with the ability to actively load balance traffic. Is my assumption that some traffic will not experience any packet loss if it is not using the failed path correct? For anyone who has used this, was the added complexity of this protocol worth it? As a general question... are people looking at implementing BFD? <http://www.ietf.org/html.charters/bfd-charter.html> Here I'm draft-familiar with what this is and I believe some vendors have code for it, but I've yet to try it. I believe the spec is held up for security and IESG review. This work looks very useful for some related applications going forward. For this crowd, is this deployable and useful for minimizing forwarding failure time? This doesn't appear to be on the roadmap for HSRP/GLBP from what I can tell, but perhaps that would a worthwhile application of BFD? Are there other things people are doing (besides plain old load sharing) to get very low latency failover? John
