It's not a question of clue, but of history. How many CS grads are exposed to the details of the development of the Internet and Information Technology? Many of us know of Jon Postel because we experienced and appreciated his work for the Internet when he was alive. Ditto Richard Stevens. Now I ask you: how many students would delve into history that deeply? How many universities/colleges/trade schools would include that information in their curriculum? Moving on...Larry Wall -- I'm finding that the new generation of people don't use Perl any more, instead favoring Python for some reason. Indeed, my current job's management insists I learn Python, even though Perl has much more support for Cisco equipment as part of CPAN. So, given that bias, it wouldn't be surprising that the up-and-coming wouldn't know who invented a tool they don't use. Guido van Rossum, they know, maybe. People exposed only to Windows may or may not know about Paul Vixie's contributions to our world -- again, it's history that would be arcane for those who never dabbled in Unix or Unix-like systems, or didn't follow Internet politics. (Yes, BIND is implemented on Windows systems -- I consult to an ISP who suffers through the pain caused by the decision to do so -- but using a piece of software and knowing the history of that software are two different things, particularly when a person isn't doing DNS admin full-time.) If your goal is to play Gotcha!, you need to go farther afield. What is ARPAnet, and what role did it play in the development of the Internet? What is XNS? What is ThickNet? ThinNet? Expand and explain CTS, RTS, CD/DCD, MR, TR, RC, TC. What is V.35? HSSI? ITU? T1 and E1, and what is the difference? And so on through ISO level 1. Who was Thomas Watson? Who was Hollerith...and how did his invention trace its origins to silk tapestry? What problem was Hollerith trying to solve? Who is (were) Ken Olson and Harlan Anderson? Throw in Ada Lovelace and Grace Hopper. What is the significance of a 30 centimeter piece of twisted-pair wire, which Admiral Hopper would hand out at lectures? What is COBOL? (And I'm not referring to the planet Kobol that is part of the Battlestar Galactia universe.) Who were Ken Thompson, Brian Kernighan, Dennis Ritchie, and Phillip Plauger? Bill Joy? And so on, and so on, second star to the right and straight on 'till morning... Here's the topper: who was (is) Al Gore, and what part did he play in the birth of the Internet as we know it today? Try not to howl as some of the answers you will get.

RE: Verizon FiOS outbound mail TLS problem - Superpages people here?
We had a similar issue around November last year where an upgrade on our PostFix MTA to a current version of OpenSSL, which has Mandatory TLS enabled for certain recipient domains, suddenly started generating the same errors with just one recipient domain. We eventually figured out that the problem was they were running an outdated version of the AsyncOS on their Cisco IronPorts. Firmware versions prior to 8.02 had several problems with TLS and one of them was an inability to interoperate with senders who used a newer version of OpenSSL. Their IronPort logs in fact showed a TLS connection was established when it wasn't. (We had switched them to Opportunistic TLS to be able to send emails but their logs still showed TLS while a PCAP showed clear text SMTP.) As soon as that company updated their IronPorts to a v8.5 variant the problem went away. They would not tell us what version they used to run but did confirm it was prior to v8.02. Interestingly, www.checktls.com said they were OK. The admins at Check TLS confirmed that, at that time (the end of 2014), they were running a version of OpenSSL on their website that was still compatible with the older AsyncOS version.

RE: Verizon FiOS outbound mail TLS problem - Superpages people here?
Oh, and the way we narrowed it down was somewhat oblique. Because their logs said a TLS connection was established we had a hard time convincing them it wasn't. They were convinced it was us who was broke. We had to send them a PCAP and then they ran one and got the same results. We were communicating via their IronPort secure email system and I noticed that the Cisco copyright notice on their messages was from 2012. That put me on the path to look at the Cisco release notes. Once I pointed out that they seemed to be a bit behind and there were fixes in later versions, the conversation went in a different direction. :-) From: sixsigm...@hotmail.com To: bl...@ispn.net; nanog@nanog.org Subject: RE: Verizon FiOS outbound mail TLS problem - Superpages people here?

Digitalocean and recent issues
Hello. I work with digitalocean droplets or virtual machines for my home business. While great for running cheap websites and server applications, I have noticed recently that I keep getting issues with my other VPN droplet I setup. Firstly, I kept getting blocked by google, it claims automated queries. I don't browse google too often.. Also had an issue with outbound mail on another droplet. Now I'm blocked by... Pizzahut.com Can't order a pizza over my VPN. One might think that there is some virus, but I assure you, there is not, Ive ran tcpdum captures and realtime captures for wireshark, I don't notice any other traffic other then the traffic I initiate by browsing, or doing a few search terms. And I've always paid for my pizza order! Is any one else experiencing issues like this? is there something I'm missing, I have no idea but the pizzahut thing has got me very irked.

Folks, It's just a piece of paper in my opinion. A person either knows their stuff or they don't. Less than 5min on a phone screen and I will know if they bought their certification(s) or earned them. Sadly, I've spoken to far too many who give some validation to Jared's comment. I'm wondering how many proctors have been paid off or if people are buying fake id's for smart people and paying them to sit for the tests posing as them. John Fraizer --Sent from my Android phone.

Kind of a cack-handed way of doing MTR, but surprising to find that it's been around since NT. New option for some of the troubleshooting from client boxen. Guess you had to buy into some of that MS certification stuff.

Tunable SFP
Anyone know if tunable SFPs exist? I've googled around on this, but only found fixed wave-length SFPs. Or of a tunable SFP+ that can operate in SFP port as 1G? Frank
