[NANOG-announce] Call for Volunteers -- NANOG Education Committee
by Steve Gibbard 29 Aug '12

29 Aug '12

(my apologies to those receiving a second copy of this. The first copy ran into a mail filtering issue and didn't go out to most of the list) At the Vancouver meeting in June, I presented a preliminary proposal for a NANOG education initiative, which would put together a NANOG-created educational program for junior (and possibly more advanced) network operators. There was broad support from the community, and now it's time to refine the idea and turn it into something that can be implemented. We are seeking volunteers to join the Education Committee and work on the final proposal and its implementation. Among the issues that need to be decided are: - What format should the classes have? - What subject matter should they cover, and what should the curriculum be? - Who should be teaching them -- volunteers from the community or paid instructors? - Where should the classes be taught? At NANOG venues before, after, or during the conferences? At independent sites at non-conference times? - Cost structures: What should the classes cost and what will be included? - Other sources of financial support: Tuition? Sponsorships? Donations? Subsidies from the NANOG conferences? - And all sorts of other issues The expected commitment from members of the Education Committee will be as follows: - Attend bi-weekly conference calls - Research issues as needed, and provide feedback to the group The goal will be to have a reasonably solid proposal in time for the October NANOG meeting, and a final proposal in time for the February meeting. If you are interested in volunteering for this committee, please contact me. Thanks, Steve Gibbard NANOG Board scg(a)newnog.org _______________________________________________ NANOG-announce mailing list NANOG-announce(a)nanog.org https://mailman.nanog.org/mailman/listinfo/nanog-announce

Thanks for the input Jon. I should note that is exactly what we are doing. The /24's are actually tagged with the advertise to customers, prepend to peers community.

No. I announce to Level3 our IP space and 2 subnets of each CIDR (i.e. /17 + 2 /18 subnets of that /17, etc.), but I use community tags (and other tricks) to mark the more specifics as advertise to [certain] L3 customers only, and let the less specifics out to the world. The only problems I've had with this have been when L3 peers have become customers, and one L3 customer doing something odd (never did find out what) that caused them to effectively null route our space until I kept them from seeing the more specifics (creative abuse of loop detection). Level3's prefix filter for your session should be built based on IRR data. If it's not doing what you want, you probably haven't setup the IRR data properly. ---------------------------------------------------------------------- Jon Lewis, MCP :) | I route Senior Network Engineer | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________

Bizarre (.bz) abuse report - are we alone?
by Jay Hennigan 28 Aug '12

28 Aug '12

OK, we're pretty vigilant about policing abusers on our network. This just showed up from "no-reply(a)abuse.bz". Please see my responses inline. Mail origin IP is from an ISP in the Netherlands. Some information redacted to protect the guilty. Is this type of thing typical these days and we're just lucky so far and behind the curve on the futility of trying to take action on reports of network abuse? -------- Original Message -------- Subject: Re: Illegal activity from 207.71.241.252 Date: Sun, 26 Aug 2012 19:13:39 -0700 From: Jay Hennigan <jay(a)west.net> To: [redacted] CC: [redacted] Sent to RIPE WHOIS contacts for mail origin IP [redacted].

This report isn't particularly helpful. In fact, it in itself is somewhat abusive of our time. First, I had to dig through the headers of the email to find a (hopefully) deliverable address to which I could respond. Second, these logs seem to be two attempts to visit a website within a very short period of time. Two tries each on TCP 80 and TCP 443. Hardly what most reasonable people would call a brute force attempt, port scan, etc. No typical exploit ports, no brute force hammering, just an attempt to connect to a web server, retried once for 80 and 443. Do you think it would be reasonable for us to query our customer and ask if someone there might have fat-fingered a web address on one of 70+ workstations yesterday, or that someone at any of tens of thousands of nameservers worldwide has fat-fingered the A record of some random website? This report appears to be robot-generated, and deliberately designed to make it difficult for a human to reply, being sent from a write-only mailbox. By masking the destination IP of a web request, you make it rather difficult to track it down in the event that it is indeed abusive in the first place. NOC personnel and resources are a finite resource. You appear to be robo-sending abuse reports that are: 1. Sent from a write-only mailbox 2. Containing logs deliberately modified to prevent tracking the abuse 3. Depicting activity that doesn't appear to be abusive Already, abuse departments at ISPs are generally shorthanded. This type of thing is even more likely to cause legitimate reports to be ignored. If you feel that this warrants further attention, please respond with a message that is: 1. Sent by a human being. 2. Has a deliverable reply address. 3. Demonstrates activity that indeed constitutes abuse. 4. Contains logs of the abuse sufficient for us to take action against our customer (such as the IP address being abused, or at least the subnet). > Here are our raw firewall logs, limited to 100 lines with timezone Central European Time.
