San Jose UUT?
by Mark Kent 22 Nov '07

22 Nov '07

Looking to fill the NANOG US Thanksgiving void (as a Canadian in the USA, I have some spare time): In San Jose, an upstream is charging us this 5% tax: http://www2.csjfinance.org/UUT.asp I think it's bogus, because the tax "applies to intrastate telephone communications only" and, consistent with the long-standing FCC 128 tariff, Internet circuits are regarded has being interstate and not intrastate. But the upstream says: >> Our tax advisors at Deloitte have confirmed that we are required to >> charge the San Jose User Utility Tax shown on your invoice. >> The Internet Tax Freedom Act exemption is not applicable to our >> services as this exemption is for internet access only, not >> bandwidth usage. I think the last sentence is not relevant, but even if it is relevant, is it correct? I note that wikipedia says: >> This law bars federal, state and local governments from taxing >> Internet access and from imposing discriminatory Internet-only >> taxes such as bit taxes, BANDWIDTH TAXES, and email taxes. I know, IANAL, YANAL, Wiki is not a lawyer... but I figure someone else must have previously dealt with this (or something very close). Thanks, -mark

Reflection Attack- 69.80.239.50
by mack 20 Nov '07

20 Nov '07

I apologize if this is off topic. Currently the IP 69.80.239.50 is the victim of a reflection attack. Many operators may be seeing what appears to be a syn attack generated by this IP. These are actually spoofed packet hitting an open port designed to generate a syn-ack packet at the victim server. This attack was originally a standard syn attack which has lasted since the 13th. On Saturday the 17th we moved the victim server to a new ip behind a firewall. Yesterday, Monday the 19th at approximately 3PM the attack changed to a reflection attack of greatly increased magnitude. We have rate limited syn-ack packets hitting the firewall to reduce backscatter of reset packets. Anyone seeing a stream of packets that appears to be improperly sourced from 69.80.239.50 is asked to contact us if they believe they can help us track back the perpetrators. Any assistance that can be rendered is appreciated. This includes direction to another forum that may be able to offer assistance. As there are approximately 102,000 reflectors being used please do not contact us unless you can help us trace this back or provide substantial assistance. We are currently overwhelmed by abuse complaints this has generated. The attack has now doubled in size and may be considerably more than 102k reflectors. ---- LR Mack McBride Network Administrator Alpha Red, Inc.

Network Solutions domain transfer lock policy?
by Deepak Jain 20 Nov '07

20 Nov '07

I just became aware of an SOP at Network solutions. On a contact change to a domain, they automatically transfer lock the domain for 60 days. I am aware of ICANN-approved behaviors like 60 days lock on new or transfered registrations. This is a new curve ball and seems a little out-of-the-spirit of ICANN regulations (last I saw them). Is anyone aware of this as a kosher activity and is anyone aware of any other registrars doing it? Keep in mind, these are legitimate contact changes and not suspicious in anyway. Thanks in advance, DJ

VLANs
by Rodney Joffe 19 Nov '07

19 Nov '07

Are any of you operators utilizing VLANs to/with your transit providers in order to isolate traffic types or services, and/or to assist in traffic shaping before it hits your transit connections (isolating the effects of DDoS's)? Would you be prepared to share experiences, do's/don'ts, gotcha's etc? Off-line responses would be fine, obviously - I don't want to add to any of the current noise.

AOL Postmaster issues
by Drew Weaver 19 Nov '07

19 Nov '07

I have a question which has been unanswerable by normal channels, I will post it here hopefully someone else has run into it and I will not waste too much of anyone's time with it. Our abuse department has been receiving e-mails daily with our feedback loop with AOL about e-mails which were 'supposedly' sent about a year ago. Does this mean that A) the message was sent almost year ago but was not read and marked as spam until today? Or b) the "abuser" is changing the date on the mail server which is messing with their means of reporting it in their feedback loops? (the second one doesn't seem likely, but if it is the case we would like to kick this guy off of our network...) (shouldn't they have some limit on how long they will allow people to report spam?) Below is the header and part of the message we're getting from AOL... From: scomp(a)aol.net [mailto:scomp@aol.net] Posted At: Thursday, November 15, 2007 3:17 PM Posted To: Microsoft Office Outlook Embedded Message Conversation: Email Feedback Report for IP -ip address removed.. why not? -- Subject: Email Feedback Report for IP -ip address removed.. why not? -- This is an email abuse report for an email message received from IP address -ip address removed.. why not? --on Sat, 30 Dec 2006 15:22:02 -0500 Thanks in advanced if any list members know, or if anyone from AOL sees this. Sorry to anyone who sees this as a waste of their time.. -Drew
