Linux w/o checking TCP sequence numbers
by Steve Francis 01 Sep '04

01 Sep '04

Not really the right forum for this, but the kindo f thing nanog'ers know: Is there a way to make Linux ignore TCP sequence numbers? My goal is to be able to have a test network with servers that a point real traffic at, mirrored off the live network. Of course, only the live servers will be responding with the SYN-ACKs, etc. The test servers replies won't make it out. So when the client replies, sequence numbers would be wrong on the test servers, and they'd kill the connection. However, I've been told there is a way to make Linux ignore the sequence numbers, and assume the packet is good. I can't find anything on google with all the thousands of patches to Linux about tcp sequence numbers, so anyone have any clues? Thanks

noc/mail admin contact for hotmail.com?

I need to get in touch with RP at hotmail, tried abuse(a)hotmail.com, which is only for consumers of hotmail, as it needs to reference a hotmail account. I tried msnhst(a)microsoft.com, but have received no response. Is there a more appropriate known address? This has to do with blocking mail at the server level. Reply off-list as preferred.

I have heard they're asking ISP's not to mirror it (and any other mirrors), and have shut down bittorrent downloads. That's understandable as they would be blamed if someone downloaded a compromised version (strange how they didn't mind Sp1 mirroring...).

Already got mine and it went nice and smooth as far as I can tell. Kudos to MS. Has anyone noticed a real impact on the internet, traffic wise, related to XP2? I'd suspect that some of the tier1's may see the traffic? Maybe not? -M -----Original Message----- From: owner-nanog(a)merit.edu [mailto:owner-nanog@merit.edu]On Behalf Of Sean Donelan Sent: Wednesday, September 01, 2004 7:00 AM To: nanog(a)merit.edu Subject: XP SP2 other than windows update On Wed, 1 Sep 2004, David A.

Expect them to use the opportunity to try to sell you some upgrades or security software. You can order a Free CD on the Microsoft web site. Although it says 4-6 weeks, people report they are getting a CD in the mail in about a week. There has been talk about Microsoft XP SP2 CD's being distribued through various consumer and business electronics stores. But I haven't seen any yet.

Every IT professional I know has had SP2 available three different ways for two weeks: 1) Somewhere on a server for support staff to begin to experiment with and for a small set of guinea pig users to install. 2) On a CD made after the download. On my CD I also have SP1 for Office 2003. Part of being an IT professional includes maintaining an updated set of CDs carried at all times. 3) On a slipstreamed install CD for new installs. Optionally, 4a) On an SP2 image on a RIS server 4b) On a ghost images The final SP2 has been available on M$ site even for people that don't have an MSDN subscription. Anyone that wants to call themselves an "IT professional" _does_ download and try major updates _before_ they are made available to end users, period. Michel.

Akamai or not, microsoft is overwhelmed by the demand for SP2, and today is giving the message listed below on windowsupdate: Download and install it now - Currently not available We are currently experiencing a high level of demand for Windows XP Service Pack 2, so please check back later for availability. We apologize for any inconvenience. If you prefer to obtain SP2 another way, the easiest way to get Service Pack 2 is to turn on the Automatic Updates feature in Windows XP and it will be downloaded when you are connected to the Internet without you having to take any further action. So then I thought about getting it from the torrent at sp2torrent.com, but sadly microsoft has made them remove the torrent... -----Original Message----- From: Byron L.

To repeat: "If you make <currently legal > Internet thing> illegal in the US, I'll just move my > <currently legal Internet thing> OUTSIDE the US Borders and > give you the middle finger as a salute." I totally agree, but have you ever met politicians that are _not_ looking to get 1) votes 2) 'political bang for the buck' 3) useless hot air blown up someone's rear? All of these are part of the job description. > Dan Hollis wrote: > the cynic in me says that the senator is looking for our > arguments in favor of p2p, so that she knows exactly how > to argue against us and exactly how to write a bill to > hurt us the most.

Fortunately for you, legislation passed by incompetent and stupid people 1) rarely gets enforced 2) even when it does, the odds of being among the few ones nailed for using a NAT box on your residential home connection are lower than winning the lottery of being struck by lightning. Some pieces of legislation are useful (such as the junk fax law or the do-not-call list) and some other that are idiotic (such as what you mentioned). > Jeff Wheeler wrote: > Not that I have any idea of MS's software activation can > translate in to protection of CDs and DVDs and whatnot, > but it's something to think about (it's certainly better > than the current mechanisms: copy once and never again, > or copy only digital files that are of a degraded quality, > or only playable on certain players to prevent copying > via a computer, among I'm sure many others). I see no future here. All attempts to protect content have miserably failed so far, as there have enough people that have perfectly legitimate reasons to break the protection. Some examples: 1) DVD zoning (nothing easier to de-zone most DVD players). I have a perfectly legitimate reason to break this stupidity: I go to France and buy a French movie in French on DVD, I can't watch it back at home. Friends visit from Luxemburg and bring movies, we can't watch them either. Even if I wanted to buy these movies, I can't, as they have not been dubbed in English and are not available in Zone1 format. This pushes me to either de-zone my DVD player, DeCSS the disc, or use this 3 megabit broadband to download a copy. Stupid. 2) Make audio CD's unreadable in a computer so nobody can rip the .wav tracks to .mp3. Totally stupid: 2.a) Remember the last ones that tried (namely Sony)? Their protection scheme could be defeated in 2 seconds with a sharpie. I'm still laughing at it. Hara-kiri comes to mind. 2.b) Even if someone could prevent audio CDs to be read in a computer (see above) it takes only _one_ person to leak the files (as demonstrated some time ago by a Madonna record leaked days before it went to manufacturing). 2.c) Anyway, given the audio quality of standard gear today, a single digital.wav -> analog -> digital.mp3 pass is not going to degrade the audio quality enough to bother anybody. In other words: connect a good CD player to a PC with a good soundcard with a grounded gold-plated cable and rip to .mp3 from the analog input, nobody will know that it's not a direct CD audio track to .mp3 rip. 3. Finally, and although it is true that copyright infringement is very often associated with P2P, I found myself downloading a lot of .mp3 files that I actually own on LP, simply because it's faster to download the file than it is to rip it from the LP (I know because I tried: I actually have a few CDs that I ripped myself from the LP). I bought the 33 1/3 album, I am entitled to a backup on another media. Michel.

The Colombo district court ordered that the vessel, 'State of Nagaland' be held at the port where it is currently anchored until the case filed by Sri Lanka Telecom is heard on September 6. SLT, the island's main telecommunications provider said they want five million dollars in damages and that internet, international dialling and data services of 800,000 subscribers had been affected since yesterday. The ship is alleged to have dropped anchor and damaged the SEA-ME-WE III cable linking Sri Lanka to the internet backbone. Services will remain interrupted for at least another day or two until a repair ship carries out its work. 8<----------- snip ----------- - ferg -- "Fergie", a.k.a.
