And what's left of ANS (the backbone back in the day), and the CompuServe Network. The chain of acquisitions of good companies prior to the WCOM meltdown was stunning.

White House may make NSA the 'traffic cop' over U.S. computer networks

...and following up on my last post, it would appear that the U.S. gummint is at least taking some action wrt U.S. gummint networks: http://www.securityfocus.com/news/10494?ref=rss Not leaping to any conclusions here, but it would illustrate that, at the very least, someone has concluded that the info- security posture needs to be approached a bit more seriously. $.03, - ferg -- "Fergie", a.k.a.

I tested the reboot. I didn't see it. I agree in general and think that providers shouldn't block tftp, IMHO.

Was that a device trying to phone home and get it's configs? Cisco, Nortel, etc. phone home and get configs via tftp. Vonage doesn't need to phone home for config. The device is programmed (router) and it registers with the call manager. If you analyze the transactions it's about 89% SIP and 11% SDP. -M<

I was set on QUUest or UUQwest for the new name, too. Verizon wins the battle for MCI, pays < 7B. http://story.news.yahoo.com/news?tmpl=story&cid=1802&e=2&u=/washpost/2005021 4/ts_washpost/a22085_2005feb13 -- Martin Hannigan (c) 617-388-2663 VeriSign, Inc.

Simply google for "PS/ALI". That's a TDM product. http://www.e911institute.org/Roundtable%20and%20Tours/June%2024,%202004/VoIP %20E911%20Issues.pdf Page 9 offers a better description of the current E911 issues. It's a software problem. All Vonage does is map your 911 call at the PSAP to your local EMS. This is a 6/24 doc. It's slightly outdated. -M< > > John >

That would indicate that Vonage still doesn't have PS/ALI, at least in your friends market. That "special" process is Vonage determining the "default" PSAP in your area and routing your 911 call to the 7-digit number for that PSAP. With PS/ALI, Vonage wouldn't be doing the routing. They would hand the call off to the 911 Selective Router which would THEN hand the call off to the appropriate PSAP based on a DIG to get your ALI information. For those of you unfamiliar with how E911 works, and specifically, PS/ALI, take a look at: http://www.xo.com/products/smallgrowing/voice/local/psali/ Or... Simply google for "PS/ALI". John

Old McDonald Had a Pharm?!
by Daniel Golding 15 Feb '05

15 Feb '05

There have been a couple recent articles about a phenomenon allegedly known as "pharming", which people are supposedly worried about. This includes some combination of DNS cache poisoning and/or worm-powered URL rewriting. This may also be a form of "fear-driven marketing" by companies inventing solutions to "fix" the problem which may not exist. (Mac Anti-virus software, anyone? ;) Is anyone aware of actual "pharming" in the wild? Please reply off-list and I will summarize answers to the list. Thanks, -- Daniel Golding Network and Telecommunications Strategies Burton Group

Phishing Name Server?
by Fergie (Paul Ferguson) 15 Feb '05

15 Feb '05

The Internet Storm Center [http://isc.sans.org/diary.php] is reporting that: "The DNS server 'NS1.SPX2K.com' currently hosts the following domains CITIFINANCUPDATE.com, SAFE-KEYNET.com, WAMU4U.com, WAMUCORP.com which appear to be phishing related. The use of actual 'valid' domains like this opens up the possibility that they are used with SSL certificates. The whois info for these domains appears to be fake." Does anyone have any further information into this? - ferg -- "Fergie", a.k.a. Paul Ferguson Engineering Architecture for the Internet fergdawg(a)netzero.net or fergdawg(a)sbcglobal.net
