Re: [NNagain] The rise and fall of the 90's telecom bubble
I started my TCP life (moving from broadcast engineering) back in about '94ish. I was in Yakima, WA and took care of the 9 working modems for Wolfe.net after being on connected.com and teleport.com (Portland, OR). My girlfriend (later my wife), who I met online via the unix talk command got hired with me by Wolfe and moved to Seattle. We worked with them for a few years during the dial-up days and moved on to one of their customers where we had massive growth and 2.5Gb/s of pipe in 1998 (yes, it was pr0n.) Then I went to AMZN and got their first netblock after haggling with ARIN at a BOF at NANOG 19 in Atlanta. See back then, AMZN could only justify a /22 since we were just a website. Many years later I landed in corporate aerospace and will likely die here at my keyboard. Anyway, now when the youngins ask me technical TCP/IP questions I like to start off with, "Well, back when we were building the Internet..."

Gee Chris, that's kind of an asinine response. Erik took the time to let

have time in my job to just go surfing around google.com to see what is
there. His mail took me about 2 minutes to read and now I know that such
info exists.

We've been using this tool since we're a LEAN company, but it actually is a good way to assign tasks/projects and delegate tasks so everyone can see what is going on. Managers can move cards to your active lane or ask why a task/project has stalled. I'm not sure what exactly you are looking for but as a team management tool, this has mostly worked for us for the last 3-4 years.

Re: DataCenter color-coding cabling schema
I know at Clearwire data centers we used gray for network, blue for management and orange for RS-232 console. At least for the initial build. Later re-work or additions were whatever the tech had on hand ;) They also had labels on each end of each wire showing the path through the system, sometimes up to six lines. It did make it easy to bring up a data center and find cabling errors. To see the system last more than a year or two up upgrades would take some strong rules and oversight. I think it would be worth it if your management system can keep the religion. -- Joe Hamelin, W7COM, Tulalip, WA, +1 (360) 474-7474 On Sat, Mar 12, 2016 at 11:11 AM, Yardiel Fuentes wrote: > Hello Nanog-ers, > > Have any of you had the option or; conversely, do you know of “best > practices" or “common standards”, to color code physical cabling for your > connections in DataCenters for Base-T and FX connections?

The two MX sites are connected via third party MPLS. The problem is when one MX site loses Internet connectivity the sending MTA may take up to 4 hours to resend and hopefully the DNS coin toss gives it the address of the site that is still connected. (Read as: French ISPs don't seem as robust as I'm use to in the US.) Since our mail traffic is international something like anycast would be nice. Now the other problem is we don't have an ASN or do external BGP ourselves. And not that it matters in a network sense, but this is a Domino mail system.

Anycast provider for SMTP?
I have a mail system where there are two MX hosts, one in the US and one in Europe. Both have a DNS MX record metric of 10 so a bastardized round-robin takes place. This does not work so well when one site goes down. My solution will be to place a load balancer in a hosting site (virtual, of course) and have it provide HA. But what about HA for the LB? At first glance anycasting would seem to be a great idea but there is a problem of broken sessions when routes change.

They distributed way they monitor would greatly reduce bandwidth overhead. http://assimproj.org The Assimilation Project is designed to discover and monitor infrastructure, services, and dependencies on a network of potentially unlimited size, without significant growth in centralized resources. The work of discovery and monitoring is delegated uniformly in tiny pieces to the various machines in a network-aware topology - minimizing network overhead and being naturally geographically sensitive. The two main ideas are: - distribute discovery throughout the network, doing most discovery locally - distribute the monitoring as broadly as possible in a network-aware fashion. - use autoconfiguration and zero-network-footprint discovery techniques to monitor most resources automatically. during the initial installation and during ongoing system addition and maintenance. -- Joe Hamelin, W7COM, Tulalip, WA, 360-474-7474

Is it just WAPs that you are worried about or any rouge device at the remote sites? If you're doing medical data then I would think that any non-company device would be suspect. If that is the case then ARP scraping is the better way. Basically you need an inventory of what is at the sites. This you should already have and if you don't, that is your first step. A bit of perl and expect scripting would get you a long way to your goal. Like I mentioned before, if you don't have the time/talent to script the task, call out for a coder-for-hire.

Kind of an ARP tripwire. Sure you'll have to take the time with early runs to hunt down non-company owned MACs but that is going to be a lot cheaper than managing a 130 site roll-out. Even if you did put RF monitoring equipment in each site you would still have to monitor and manage it. Either way, you'll be getting a current inventory of devices. From what I read, he wants to detect non-company equipment on his network. It's just WiFi that is the main problem. Even just watching the DHCP leases, which I assume the little Cisco router is providing, will catch most of the rouge devices. Get someone that knows networking and perl on the task for a month. If they don't have the local talent there are a lot of people that would love to take the contract, considering most of it could be done remotely. Jonathan stated that they have health data on the network and only company issued devices are allowed. I would suggest to him that he inventory the equipment via MAC address (I'm guessing that it's mostly standard issue stuff that would be easy to recognize) and then lock down unused ports and setup up monitoring. If a new MAC appears on the network, then it better have been sent there by IT. -- Joe Hamelin, W7COM, Tulalip, WA, 360-474-7474

Brother PT-1400 P-Touch Handheld Labeler ($90ish) is nice in that it will do three lines and also do "flags" (double print) to tag wires with. Batteries last a good while, and fits in the hand nicely. Good for field work and fairly rugged. Main downside is lack of a qwerty keypad.

Or that most ADSL lines have about 20% ATM cell "tax" on them. I did get caught up on a speed test today. I was turning up a GBLX 100Mb circuit. I got the /30 and all the pings were good to the router. I then pinged some known hosts in the Westin (about a block away where GBLX's router was) and saw some not so nice ping times. I then ran a speedtest and only got about 2Mb/s. Come to find out that this was going to be an MPLS path to the company's California office. Since it hadn't been setup fully the router had found some path through it's management network to ping the world through the tester's DSL line on the other side. So, know the path you are testing. -- Joe Hamelin, W7COM, Tulalip, WA, 360-474-7474

They do come with a static IP address if you request (and pay?) for it. They can come from the shared mobile IP range (RFC 2002) so that you can keep the static IP as you move between tower sites. You can also get them "piped" right in to your net via a VPN, although I suspect that is only affordable for a very large install base. Real world 3G bandwidth is about 1Mb/s down and 300Kb/s down. RTT (ping) is around 185ms to a local IXP (which kinda sucks for terminal support, but still better than a POTS modem.) -- Joe Hamelin, W7COM, Tulalip, WA, 360-474-7474

Now I'm going to have to look at the current gethostbyname(3) and see what happens if we ever get a tld that is a decimal number under 255.

I remember tales from when there was an eight character limit. But that was back when you didn't have to pay for them and they assigned you a class-c block automatically. Of course it took six weeks to register because there was only one person running the registry. -- Joe Hamelin, W7COM, Tulalip, WA, 360-474-7474

Re: How to begin making my own ISP?
When we needed an ISP in Yakima back in '95 we found a rich guy in Seattle, got him to hire an old SunOS geek and an illegal Englishman, and a very small space on the 19th floor of the Westin. Then we talked him into putting his first POP in Yakima where he would have immediate paying customers. He was tired of using broken UUCP email for his trading company. That was our "hook". That ISP founded what is now SIX, so not all was lost. j...@wolfe.net -- Joe Hamelin, W7COM, Tulalip, WA, 360-474-7474 On Fri, Sep 16, 2011 at 6:41 PM, Ben McGinnes wrote: > On 17/09/11 7:34 AM, Charles N Wyble wrote: > > On 09/16/2011 04:28 PM, hass...@hushmail.com wrote: > >> On Fri, 16 Sep 2011 16:02:39 -0400 Markus > >> wrote: > >> > >> I didn't receive any such email, sorry.

Re: Tampa small colo recs?
The switch & data (or whatever they are called now, Equinox or something) space is nice, good manager. You'd have to go for a whole rack or cage though. You'd have wikipedia as a neighbor too. I put 40+ racks in there for Clearwire. They are in the building with the big lizard on the side downtown Tampa, 10th floor if I recall. -- Joe Hamelin, W7COM, Tulalip, WA, 360-474-7474 On Thu, Sep 1, 2011 at 5:50 PM, Jay Ashworth wrote: > Anyone got any opinions on small colo rental in Tampa; anywhere from 8RU to > a > half-rack?
