Calling Comcast Postmaster or whomever actually is responsible for Comcast RBL maintenance
by Chris Stebner 03 Dec '09

03 Dec '09

For over a month now I've been fighting with Comcast Customer Security Assurance regarding a simple BlackList issue. Apparently there is some disconnect between internal applications and their ability to report BlackList status accurately and the 'actual' BlackList rule-set. Supposedly the ticket has been escalated to 'admin' and 'engineering' multiple times to no avail. Currently we are waiting for engineering again to examine the issue. The block is owned by us, a facilities based CLEC in business for over 10 years. The /24 in question is used for business T1's. If anyone has any contacts, ideas or the power to resolve the issue I'd be elated to hear from you. Thank you all for your time, Chris Stebner 970-403-0102

AT&T SMTP Admin contact?
by Brad Laue 03 Dec '09

03 Dec '09

Hi all, Would I be able to get an AT&T mail administrator to contact me off-list? We've recently moved our mailservers to a new IP address range, and the standard CGI forms haven't produced any progress for us in over a week now. Unfortunately this affects dozens of hosted clients... The CGI form at http://wn.att.net/cgi-bin/block_admin.cgi has also got a dead link at the bottom, which shakes my confidence in its level of maintenance a little. Thanks in advance, -- Regards, Brad Laue Systems Administrator, Inftek Hosting 1-888-44-SYNCD http://www.getsyncd.com (888) 44-SYNCD (888-447-9623) x702

New European IXP customer tool
by Serge Radovcic 03 Dec '09

03 Dec '09

Just wanted to announce that we published a handy little tool for those either already, or interested in, peering at an European IXP(s). The Euro-IX ASN filter allows one to make use of our IXP database that contains more than 4.800 ASNs that peer at IXPs around Europe. You can see which ASNs peer where and what the overlap is between multiple IXPs and, well more....just try it out and see. https://www.euro-ix.net/member/m/asnfilter All feedback is welcome Serge Euro-ix

What are people supposed to do with that info? For instance some ISPs or Freemail providers give their customers the possibility to use SPF as a value added service to decide if "senders domain" should be dropped in theirs suspicious-folders or not . I also learned that SPF is qualified for senders reputation : http://www.ceas.cc/2006/19.pdf > Spamassassin assigns it a score of 0.6 but that is low enough it really > doesn't have much since it doesn't assign any negative points for > SPF_PASS. > > (And before anybody asks, yes ~all is what we want, and no you can't > ask us > > to try -all instead, unless we're allowed to send you all the > helpdesk calls > > about misconfigured migratory laptops".. ;) > I certainly understand that you may not be able to lock down your > domain.

Flash Media Servers as Open Proxies
by Marshall Eubanks 03 Dec '09

03 Dec '09

I recently found out that the Adobe Flash Media Server (FMS) can operate "out of the box" as an open proxy, enabling other people to steal server resources and bandwidth. Furthermore, I also found that there is an ecosystem of pirates taking advantage of this "feature" to illegally stream sports events (and maybe other stuff as well). Each event uses multiple (stolen) servers and can amount to thousands of streams and Gbps of consumed bandwidth. I believe but am not 100% sure that there are similar problems with Window Media Servers. I would like to hear (off-list) from people who have experience fighting this so that we could maybe pool techniques. I will try to write this up further later. Regards Marshall Eubanks

Comcast outage in central NJ
by Jeffrey Negro 03 Dec '09

03 Dec '09

There appears to be a Comcast outage in central NJ, more specifically in the South Brunswick area. Comcast appears to be aware of the outage as per the message I got when I called them. Anyone hear any details on the issue, or an ETA for repair yet? Jeffrey
