routing sniffed traffic
by Patrick Arguello 08 Oct '04

08 Oct '04

In my datacenter, I have three Gig links coming in that I am sniffing using passive taps. What I want to do is feed these links into a layer 3 switch so that I can have them sent to different packet analysis boxes by destination address or packet types or ports. What should I look for in a switch for such a use -- something that can take in sniffed traffic on fiber gig links and parcel them out to different servers on copper gig links based on routing rules. Please email me your recommendation or suggestion directly and I will summarize what I find out for the list. Thanks, Patrick A. __________________________________ Do you Yahoo!? Y!

short Botnet list and Cashing in on DoS
by J. Oquendo 07 Oct '04

07 Oct '04

I've been slowly compiling a list of known botnets should anyone care to filter, or check them in your netblocks if someone in your range is passing off garbage, etc. Information has been passed from others admins having to deal with these pest. Care to pass on a host that you're seeing I'll post it for others to see as well. Perhaps when I have spare time, I may or may not throw up something where admins can check, add, hosts they're seeing. Don't know if I want my connection getting toasted for doing so, but it could be something informative, a-la spamhaus. Bothaus anyone? http://www.infiltrated.net/sdbot-irc-servers.txt ------------- Virus writers seek cash from chaos By John Leyden The Register http://www.theregister.co.uk/2004/10/06/vxers_cash_in/ Last month Trend Micro, the anti-virus firm, recorded a six-fold increase in malware compared to September 2003. It detected 1,485 new items of malware last month, compared to 250 new types of malicious code in the same period last year. ... Trend also records the emergence of the first JPEG virus in September, and notes that the most damaging variant of the Sasser worm - Sasser-B - is still prevalent four months after its first appearance in the wild. ------------- =+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+ J.

follow-on of maintenance survey
by Zhen Wu 07 Oct '04

07 Oct '04

Several hours ago, I post a survey request on the list. First, if it disturb some people, please accept my sincere apology. Second, I'd like to summarize the responses, because I think it might be interesting to some people. I got about 30 responses, which is not a big size. Most people said that they do the planned maintenance during weekday midnight. Two reasons for this. First, it's the time window that will cause the least interference of network usage; Second, it's a better time to get hold of other people (customers, vendors) than weekend if necessary. For some small or critical problems, people just fix it immediately. Some people also mentioned that they would like to major maintenance during weekend. Third, I will explain our research (routing instability) and hypothesis, which motivate this email survey. Your sharing of insight will be very helpful and appreciated. Because it's pretty long, I put the description in the end. Finally, we still warmly welcome your survey response. Thanks! Zhen ----------------------------------------------------- In the academic research society, some people argue that there is correlation between network usage and Internet routing instability (of BGP). A research done in 1996 revealed daily and weekly routing instability pattern. During the day time Internet exhibits significantly higher instability, while in the midnight we see much less instability activity. Similarly, during weekend there are much less routing instability. We revisited this study, because we believe Internet has changed a lot since 1996. We use data from public BGP archives like Oregon RouteViews. Our new results still display pretty strong daily pattern, with higher instabilities during 6AM and 6PM (PST). However, we observe less obvious weekly pattern compared to 1996. Our visual comparisons are also confirmed by more rigorous statistics method: spectrum analysis (using Fourier Transform). Meanwhile, Internet traffic still display strong weekly and diurnal patterns. So if we believe the correlation between network usage and routing instability, why we didn't see less instability during weekend? That's why I send out previous survey email to see whether people do a lot of maintenance during weekend, which might contribute to some of the instabilities observed during weekend. From current survey, my hypothesis seems not to be true. Any discussion, insight, or critique are extremely welcomed!

MPLS Book Recommendation

survey of maintenance time
by Zhen Wu 07 Oct '04

07 Oct '04

Dear administrators: I am a PhD student from Univ of Oregon. We are studying the characteristics of Internet routing instability. I have a very simple survey for the administrators. Do you mostly do the system maintenances during the weekend in order NOT to interfere network usage during weekdays? Here I mean maintenances like change routes, replace devices, change configurations... The more response, the better :) Your cooperations are greatly appreciated! Zhen Wu

CWDM Test Gear
by Deepak Jain 07 Oct '04

07 Oct '04

(If there is enough interest I will summarize to the list, or privately amongst the interested). Can anyone recommend a few relatively simple-to-use pieces of test equipment one could use to test say: a) the presense of a lambda [or multiple ones] in the CWDM range on a piece of metro fiber, b) the color of each lambda, c) other cool things. If the signal is there, the SFP can give us most of this info. The idea is that for set up, testing, repair of a working system I'm looking for a couple of out-of-band items that are relatively trivial. I don't want to deploy an OTDR test kit at every POP if I can avoid it. suggestions are appreciated! Thanks, Deepak Jain AiNET

spanned traffic routing
by Patrick Arguello 07 Oct '04

07 Oct '04

How can one take spanned packets from a mirroing port and use a L3 switch to "classify" and route it to different servers. Would it be the same if the packets were coming from passive taps? Worry I have is if the L3 switch ports would drop the spanned packets because the ports usually cannot be set to promiscuous mode. (Hopefully the L3 device that can do what I want ought not to be expensive.) Pls correspond directly with me Thanks! - Patrick A. --------------------------------- Do you Yahoo!? vote.yahoo.com - Register online to vote today!
