[NOTE: I am biased toward this one, for some personal reasons ;)] I would highly recommend you to read some of the papers of the gold certified SANS people - start here: http://www.giac.org/certified_professionals/listing/gcia_100_781.php 2. Another option is getting Richard Bejtlich's books "Intrusion Detection ..." & "Extrusion Detection ..." and getting some ideas from that material. Regards, [another] Stefan
[OT] Connexion {Was: Re: [routing-wg]BGP Update Report}
Just wondering this, myself. I travel fairly frequently between US and Europe, and Lufthansa was recently my choice, exclusively because of this service. Perhaps with the interdiction of computing devices on board (have not travelled since the UK incident, so I am not sure if the new rules of flying naked affect all flights?!?) there won't - obviously - be much of a need for an Internet connection ...

As many have mentioned here, TIA/EIA-942 is a good starting point. There are a couple of good Data Centers books out there, also (a visit to your local Borders or B&N could allow for an interesting afternoon browsing). I have personally had positive experience with some docs and advice from some folks with expertise in cable management and data centers infrastructure: http://www.panduit.com/enabling_technologies/091903.asp HTH, Stefan
Re: OT: Good list for VoIP
I've had some decent success with other lists from this site: http://isp-lists.isp-planet.com/about/ so you may want to try their VoIP one. I cannot personally endorse that specific one, though, as I am not a subscriber.
