At a recent large (last 6 months) trade show, the show network saw a bunch infected systems pop up at once. The problem was tracked (fairly quickly) to machines brought up by a vendor in their booth that lacked a number of recent Microsoft Windows Critical Updates. I can't say who the vendor was, but they REALLY should have been the FIRST to install any patches. If this happens, what hope do we have for "normal" users. -- R.

>buy a 1U, put it in a colo center (should cost you about $50/month) and >proxy all your outbound mail from there. stop thinking of broadband as >anything other than a lastmile protocol between your house and your own >piece of the internet core. This is darn good advice. And to expand on it further, it is time to stop thinking of Simple Mail Transport Protocol (SMTP) as the way for everybody to send email. For some strange reason we have managed to develop two protocols for end users to use in talking to their mail service provider (POP and IMAP) but neither of them allow the end user to send email. One would think that an authenticated session with an email service provider would be the natural protocol to use for injecting end user email into the system. Imagine a world in which only ISPs run SMTP servers which only talk directly to other servers with which they have an offline relationship. A world in which everybody hands over their email to an ISP for onward delivery in order to get it into the system. A world in which it is virtually impossible to send anonymous or forged email without the cooperation of an ISP. To get to this world we have to stop trying to fix the SPAM problem. Instead, we have to fix the email architecture problems which have created the environment in which SPAM can thrive. A new architecture might not prevent SPAM but if it makes spamming hard to do and has rate limits that make it very hard to do high volumes of unauthorized email then most people will not care about the small volume of SPAM. We need to start with an Email Service Consortium with a code of email server practices in which the larger ISPs agree to stop accepting SMTP connections from anyone who is not in the consortium or a customer. This will get everyone implementing a set of well-known and consistent controls. We need to add email sending capability to both POP and IMAP so that eventually we can all block port 25 entirely from broadband/dialup edges. And we need to reinstate the use of SMTP relays in order for smaller ISPs to have access to the core of the email system. --Michael Dillon

IPSEC server at NANOG30 (fwd)
by Susan Harris 09 Feb '04

09 Feb '04

Hi everyone - here's a note from Duane Wessels, who handles many of our critical services at NANOG meetings (DNS, DHCP, caching, etc.) If you're interested in beta testing and would like to talk FTF, he's wearing a really really bright orange T-shirt and sitting in the front of the ballroom. ---------- Forwarded message ---------- Date: Mon, 9 Feb 2004 14:52:00 -0700 (MST) From: Duane Wessels <wessels(a)packet-pushers.com> Hi, We are experimenting with an IPSEC service that NANOG attendees may be interested in using to encrypt and secure their wireless traffic during the meeting. We have an IPSEC server on the meeting network and are looking for a few beta testers to try it out. We can currently work only with Linux and *BSD systems. In order to use the IPSEC server with Linux, you must have FreeS/WAN and iptables installed. BSD users should have isakmpd installed. If you'd like to try it out, or have any qwestions, please send a message to Duane Wessels, wessels at packet-pushers.com.

Hardening a control plane
by Frank P. Troy 09 Feb '04

09 Feb '04

Hey Folks, I'm looking for information on various core network architectures that could harden a control plane or prevent/isolate the propagation of say a malformed packet/control plane issue. I know that a part of the problem can be solved with edge filtering, ebgp, defense in depth and MD5 auth, but I am looking for a solution that might involve multi-level IS-IS. Any pointers would be a help. Thanks Frank -- ========================= Frank P. Troy frank(a)troy-networks.com =========================

What I retain from your very good post is that if _you_ are having trouble resisting the siren song, there is nothing to do for the typical non-technical CEO, as all they care about is feature and ease of use. Microsoft may be crap, but as long as the users are screaming for it, no problemo. After you've shown them that they can have their email, calendaring, contacts, etc in their cell phone, that their administrative assistant can manage it from the office, and that it fits in their shirt pocket and is updated quasi real-time, the sale is over. Real story: A month ago I had a non-technical customer that used her windoze cell phone to open a critical m$ word file from the basement of capitol hill. One can whine all they want about Outlook, if one does not provide a solution that looks as good IN THE USER'S MIND, one will continue so see Outlook being the dominant app and Windows being the dominant OS.
