OT? experience with time warner telecom?
by Matt Hess 16 Jul '04

16 Jul '04

Apologies if this is off topic but we are looking at time warner telecom for an upstream connection and I would like to get some info as to people's experience with this group.. good or bad. Off-list is fine.. especially if this is indeed OT.

as path filtering -- cisco implementation
by Philip Lavine 16 Jul '04

16 Jul '04

Is inbound as-path filtering an efficient way of preventing routes from entering your bgp table? How come the filtered routes still show up in the bgp table and not in the routing table? What is hit on the CPU? __________________________________ Do you Yahoo!? New and Improved Yahoo! Mail - Send 10MB messages! http://promotions.yahoo.com/new_mail

There is some private FTP server use in the US as well; it is difficult to measure the bandwidth it uses, as it often involves encryption and therefore is inventoried as miscellaneous traffic by probes. I am not a hardcore file swapper, but like everyone else I granted access to my FTP to a few buddies. However, it works only over VPN: no static IP and no encryption, no FTP (there also is an unwritten clause about red wine). I believe that Europeans tend to underestimate American private FTP usage (and vice-versa) because it is more difficult for someone from the other side of the pond to penetrate the relatively private circles of private FTP file sharing. > With proliferation of 10 meg ethernet (full duplex) connections > for residential use in (especially) northern europe and in asia, > users are more likely to serve content to other users around the > world. Note that 10meg Ethernet full-duplex is becoming available in the US as well. Where I live (Sacramento, California) we have this: http://personal.surewest.com/internet/highspeed10mb.php Note that they cap the service at 40 GB/mo, which still is ~40 movies, more than I can watch :-) > My interpretation of this is that p2p networks are quite > intelligent in using the available bandwidth, and that > Copyright holders only solution is a "content crunch" due > to providers limiting their users upload potential due to > heavy usage, such as capping the amount of bandwidth > allowed per month or alike. I agree, but see above: a 40GB/mo cap is not something that I care about. Granted, I'm not a hardcore file swapper but 40GB/mo are more than enough for most including myself. As shown here: http://arneill-py.sacramento.ca.us/mrtg/192.168.222.1_et0_0.html My usage last month was 2 GB and the average over the last 20 months was 8GB/mo. And I do share some files. > Petri Helenius wrote: > If you leave BitTorrent out, which is probably the fastest > growing protocol out there, the statistics are missing about > one third of the bits moved. BitTorrent is a third of p2p traffic in Sweden? Wow. In the US it is a small blip on the radar. My reading about the big five is as follows: +------------+-----------------+---------------------------------------+ ! Protocol ! Typical client ! Comments ! +------------+-----------------+---------------------------------------+ ! FastTrack ! Kazaa ! Declines everywhere. Privacy concerns ! ! ! ! are killing it in the US. ! +------------+-----------------+---------------------------------------+ ! WinMX ! Winmx ! Stable client, stable market share. ! ! ! ! Fit for MP3s, not for warez or movies ! +------------+-----------------+---------------------------------------+ ! Gnutella ! various, a mess ! Doomed to disappear sooner or later. ! +------------+-----------------+---------------------------------------+ ! eDonkey ! mostly eMule ! Fastest rising in the US (at the ! ! ! now ! expense of FastTrack, mostly). There ! ! ! ! are more than one client but it's not ! ! ! ! a mess like Gnutella. Fit for large ! ! ! ! files, for MP3s initial queing has ! ! ! ! pushed lots of users back to WinMX ! +------------+-----------------+---------------------------------------+ ! BitTorrent ! BitTorrent ! New; reported fit both for large ! ! ! ! files and MP3s however privacy ! ! ! ! concerns are as high as Kazaa and the ! ! ! ! interface is not nearly as polished ! ! ! ! as WinMX or eMule. Too early to call. ! +------------+-----------------+---------------------------------------+ Crystal ball reading: Gnutella will disappear. WinMX and eDonkey will eventually eat FastTrack (numerous swappers use both WinMX and eMule); BitTorrent is an outsider. Regional differences between Western Europe and North America will blend; Asia/Pacific too early to make predictions. Michel.

Here's a small question that might take a big answer. Is there any open source tools that can help organize and facilitate "Network Change Processes"? If not, what are some of the tools you reccomend using to organize and coordinate moves, adds and changes?

Most of the lastest versions appear to install themselves using the ByteCode Verifier vulnerability in the Microsoft Virtual Machine. Fully patched systems don't get the stuff installed. I'm sure the authors are working on newer injection methods.... Though the blame might be placed on Microsoft for having a flaw in their code, this wasn't part of any IE feature. You can read more about this exploitable bug (not feature) at http://www.microsoft.com/technet/security/bulletin/MS03-011.mspx >I do not blame MS, but what about spyware on MAC-s - is it so easy >to write and install spyware there? I don't really want to get into the argument of why people choose microsoft products to attack, but if someone was going to choose a product to attack, from which they were going to try and make the most money/impact off of, do you think they would choose the product with the largest user base? I think that's the case here. It would be a poor business decision not to, and these people are definetly out to make as much money as they can off of these exploits. >This is 100% legal at this point (and even if it is not legal, >who bored about it outside of USA? No anyone!). It really shouldn't be legal. It is someone gaining unauthorized access to computer systems and altering data on those machines. Not to mention that people are profiting from these intrusions. -Brian

> I don't know of any capped service over here, nobody dares take the first > step. Not 10 Mbps but: Telenor, the largest Norwegian service provider, capped their ADSL customers at a ridiculously low 1 Gbyte/month for a while. Presumably they lost sufficient business to other (uncapped) providers that they noticed - the cap has now been removed. Steinar Haug, Nethelp consulting, sthaug(a)nethelp.no

Re: Controls are ineffective without user cooperation

...and security, access-controls, etc. have to have a transparency and ease-of-use factor such that legitimate users don't actively attempt to bypass it themselves. :-) - ferg -- Sean Donelan <sean(a)donelan.com> wrote: Donn S. Parker pointed out controls are ineffective without user cooperation. According to an AT&T sponsored survey, 78% of executives admitted to opening attachments from unknown senders in the last year, 29% used their own name or birthday as a "secure" password, 17% accessed the company network in a public place and didn't log out, 9% informally shared a network password with someone outside of the company. http://www.att.com/news/item/0,1847,13137,00.html The survey included relatively few people, 254 executives from Europe, North America ans Asia-Pacific regions. -- "Fergie", a.k.a.
