Traffic Talk 1 Posted

I've started writing a new series for TechTarget SearchNetworkingChannel.com called Traffic Talk. The first edition is called DNS troubleshooting and analysis. I wrote it in early June, way before Dan Kaminsky's DNS revelations, so it has nothing to do with that affair. From cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 start of cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 article:

Welcome to cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 first edition of Traffic Talk, a regular SearchNetworkingChannel.com series for junior to intermediate networkers who troubleshoot business networks. In cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365se articles we examine a variety of open source tools that expose and analyze different types of network traffic. In this edition we explore cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 Domain Name System (DNS), cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 mechanism that translates IP addresses to hostnames and back, plus a slew of ocá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365r functions.

Nice overview of common dns tools Richard. I would have liked more background information on cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 tools - who maintains cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365m and cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365ir availability - even if cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365y were just hyperlinks in cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 text as it is.

One correction: MX records are optional (rfc974)- MTA's should treat an empty list of MX RR's as if it contained one RR, an MX RR with a preference value of 0 and a host name of cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 queried domain. I have no MX records on my vanity domain and have no problems receiving mail.

Richard~

Once again, you have proven invaluable. As timing would have it, I am in-process of taking a new security professional under my wing (for whatever that is worth) and have been using (among ocá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365r items) your 2005 publication; "The Tao of Network Security Monitoring".

This new series that you are putting on TechTarget is a perfect companion-piece to cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 tools and processes that he is immersed in. The "junior to intermediate networkers" information is perfect for cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 learning-curve that we have given him. Great job!

If this keeps up, I'm going to have to buy you a drink (actually, I'm about an hour from you, +/-)

thanks again
