activecm/passer: Passive service locator, a python sniffer that identifies servers, clients, names and much more
Passer can work off a live packet capture or from a pcap file (command line parameter, see examples below). It reports live services and clients, ethernet cards on the lan, dns entries, operating systems, and routers - all passively!

Every Linux networking tool I know
Do you ever feel like there are like 50 different linux networking tools that all do different things and it’s impossible to keep track? That’s because there are about 10 billion linux networking tools. This isn’t even including web/dns servers like apache / nginx / unbound, just regular command line tools! So I made this fun poster with a super short description of each one, in the hopes that it’ll help you keep track and maybe find some new tools to learn about.

GitHub - Microsoft/ethr: Ethr is a Network Performance Measurement Tool for TCP, UDP & HTTP.
Ethr takes inspiration from existing open source network performance tools and builds upon those ideas. It is very similar to iPerf3 for bandwidth measurements for TCP. iPerf3 has many more options for doing bandwidth measurements such as throttled testing, richer feature set, while Ethr has support for multiple threads, the ability to scale to 1024 or even higher connections, multiple clients to a single server etc. It is similar to latte on Windows or sockperf on Linux for doing latency measurements.

Ethr is natively cross platform, thanks to golang, as compared to compiling via an abstraction layer like cygwin that may limit functionality.

Errata Security: TCP/IP, Sockets, and SIGPIPE
There is a spectre haunting the Internet -- the spectre of SIGPIPE errors. It's a bug in the original design of Unix networking from 1981 that is perpetuated by college textbooks, which teach students to ignore it. As a consequence, sometimes software unexpectedly crashes. This is particularly acute on industrial and medical networks, where security professionals can't run port/security scans for fear of crashing critical devices.

Building and scaling the Fastly network, part 1: Fighting the FIB
This post is the first in a series detailing the evolution of network software at Fastly. We’re unique amongst our peers in that from inception, we’ve always viewed networking as an integral part of our product rather than a cost center. We rarely share what we do with the wider networking community however, in part because we borrow far more from classic systems theory than contemporary networking practice.

QOTD: Are You Ready For Showroom Neutrality? - The Truth About Cars
Think of the benefits to the public if every dealer was treated as a utility. You could get a Ferrari delivered to you in Peoria, or a Tesla in rural Alabama. The dealers might not like it, and some of the manufacturers might not like it, but the same was true of Comcast and Verizon during the Net Neutrality period. Most people don’t have all the dealerships near them. Why should they be penalized for a monopolistic lack of common infrastructure?

Or maybe something seems wrong to you about that. Can you articulate it logically? Or will the tide of American business continue to turn in the favor of the oligarch disrupters, regardless of its impact on local business?

​Comcast vs. Netflix: Is this really about Net neutrality? - CNET
Netflix could fix this problem in one of two ways. It could pay for a fire hose connection instead of taking the garden hose connection that it can get through a standard peering relationship with Comcast. The large connection would accommodate the Netflix traffic. The other option is to distribute its traffic more evenly among other CDNs that are delivering traffic to Comcast. In this case, the video traffic could get onto the Comcast network via the many garden hoses already connected to the Comcast network.

World’s Fastest Broadband at $20 Per Home - Bits Blog -
Cable executives have given several reasons for why many cable systems in the United States are going very slowly in upgrading to Docsis 3. There’s little competition in areas not served by Verizon’s FiOS system, which soon will offer 50 Mbps service. And some argue there isn’t that much demand for super-high speed.

Mr. Fries added another: Fear. Other cable operators, he said, are concerned that not only will prices fall, but that the super-fast service will encourage customers to watch video on the Web and drop their cable service.

The industry is worried that by offering 100 Mbps, they are opening Pandora’s box, he said. Everyone will be able to get video on the Internet, and then competition will bring the price for the broadband down from $80 to $60 to $40.
