RE: Effects of traffic shaping ICMP (&c.)
by Martin, Christian 02 Dec '98

02 Dec '98

You could implement priority queueing to this end, but the effects could be disastrous on buffers. At this time, the best way to defend against smurf and UDP floods is via access-lists with fast-packet drop.

Winter NANOG meeting
by Susan R. Harris 02 Dec '98

02 Dec '98

Hello everyone - registration is now open for the next NANOG meeting, to be held January 31- February 2 in Denver: http://www.nanog.org/mtg-9901/ Hope you can join us! Just a reminder that slides and RealMedia recordings from the Atlanta NANOG are available here: http://www.nanog.org/mtg-9811/agen1198.html We are still looking for a sponsor for the upcoming spring NANOG (NANOG 16). If you're interested in hosting the meeting, please send e-mail to nanog-support(a)nanog.org. Also, we welcome equipment and break sponsors for the Denver NANOG. If you are interesting in loaning equipment (hubs, caches, wireless), or sponsoring a break, please send e-mail to nanog-support(a)nanog.org. --Susan R. Harris

Re: identify hostname
by Dean Anderson 02 Dec '98

True enough. But it would cut out most of the the problems with really small customers (such as the /30's which were mentioned ;-) Sure there are some cases that are hard or impossible to account for, but it would be helpful for ISP's to take a stance that "here's your address space. Unless you tell us otherwise, we assume its not subnetted, and we will block your broadcast addresse. If you subnet or otherwise change your broadcast address, you will need to notify us" I guess what I'm saying is that for many, the default is to do nothing. The default should be different where possible. --Dean >That works fine as long as you either manage your customers' equipment or >your customers don't subnet blocks you give them.

Windows TweakDUN issue..
by bcurnow 02 Dec '98

02 Dec '98

In regards to the topic, is there a _technical_ discussion, perhaps written by someone here, on what is broken in Win9x that makes these kinds of software useful? I find it disturbing to read that MS makes 576 the default in 98, while still seeming to produce an ack for every packet on TCP. I think being able to single handedly reduce the number of packets sent by 25% should have been a high priority for them. Instead they choose to triple it. Or am I in need of a higher RFC exposure? ----------------- Brian Curnow ----------------

This has all been discussed before. A US Attorney has spoken. The Congress has spoken. They both said you are wrong.

BBBZZZTTT yourself. Blocking email is an interception under the ECPA (18 USC 2511 et al). It has been reported here previously that 1) The ECPA was amended to apply to email. 2) A US attorney has stated that ISP's who define their service to include mail filtering for their customers implicitly have their customers permission to do so, as required under the ECPA. Those who don't have permission would be in violation of the ECPA were they to block email. So as twisted as his writing and perhaps his thinking is, Bob is essentially right on that. You, as usual, are unequivocalably wrong. Perhaps you also can quit wasting our bandwidth. --Dean >*BBBZZZZTTT*, wrong answer,thank you for playing. Prevention of email >delivery is not interception. Nor is there reading of your private email, >or any of the other horrible crimes against humanity that so many envision. > Unlike the USPS, if you don't like your ISP's email policies, you are free >to go elsewhere. Your argument has no basis in legal, moral or ethical >theory. > ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Plain Aviation, Inc dean(a)av8.com LAN/WAN/UNIX/NT/TCPIP http://www.av8.com ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
