DSL inventor's latest science project: terabit speeds over copper
Wednesday, 10 May 2017 12:56

John Cioffi, known as the “father of DSL”, reckons we're nowhere near the limit of copper transmission speed, delivering a presentation claiming Terabit performance is feasible.

Feasible with a bunch of caveats, that is, the two most important of which are “if research delivers on theory”, and “if it can be standardised”.

The basis of Cioffi's proposal in this PDF presentation is that at high enough frequencies, signals in copper behave differently to at low frequencies.

At the kinds of frequencies we use for today's DSL, the signal is carried by the movement of electrons in the wires. If, however,

Son of Sonoff
Saturday, 13 May 2017 22:00

We’ve covered the Sonoff a few times–a very inexpensive box with an ESP8266, a power supply, and an AC relay along with a way to tap into a power cord. Very inexpensive means $5 or $6. The supplied software will work with several systems (including, recently, Alexa). But what self-respecting hacker wants to run the stock firmware on something with an ESP8266 inside?

[Tzapu] certainly didn’t. But he also knew he didn’t want to start from scratch every time he wanted to deploy a switch. So he built SonoffBoilerplate and put the code on GitHub. The code manages taking configuration …read more

A switch with just 49 ns latency? What strange magic is this?
Thursday, 27 April 2017 13:57

Australian company Exablaze has released a switch with claimed latency of just 49 nanoseconds.

The ExaLINK Fusion FastMux is designed for those who can't wait for data to make it through a box, especially high-frequency traders but also HPC types.

The device isn't a switch to rank with the likes of Cisco or Arista, because it's not designed to carry traffic from one port to any other. Instead, it aims to move data from its 15 incoming ports into a single outgoing port, or the reverse.

That goal means the device doesn't have to bother about layer 3 and that,

Fistful of flaws blow away SolarWinds network appliances
Thursday, 27 April 2017 13:03

Admins of SolarWinds system management systems can block out a biggish chunk of their diaries to implement a bunch of serious patches.

There are five bugs of varying seriousness in the company's Log and Event Manager appliance discovered by KoreLogic and posted to Full Disclosure.

Four of the bugs depend on an attacker accessing the appliance's SSH shell and logging in as cmc , if the admin has left that user's default password – password – in place.

First, there's a sudo path that's a privilege escalation vector : an attacker only needs a bit of directory traversal to execute

FTP becoming Forgotten Transfer Protocol as Debian turns it off
Thursday, 27 April 2017 10:57

Debian is shutting down its public File Transfer Protocol (FTP) services, because hardly anybody uses them any more and they're hard to operate and maintain.

The project has told world+dog that come November 1st, 2017, ftp://ftp.debian.org and ftp://security.debian.org will cease operations.

The reasons are pretty simple: Debian contributor Cédric Boutillier says “FTP servers have no support for caching or acceleration”, which probably means Debian has to throw more hardware at FTP than is sensible. He also notes that most software implementations "have stagnated and are awkward to use and configure...the protocol is inefficient and requires adding awkward kludges to firewalls

HPE kills off its entire OpenSDN line, pulls plug on customer demos
Thursday, 27 April 2017 08:13

Exclusive Hewlett Packard Enterprise has quietly axed its OpenSDN suite, effective immediately.

Its sales staff have been instructed to shut down customer demos and proof-of-concept installations. IT buyers will be told to try other gear if they want to evaluate and roll out software-defined networking.

HPE workers have also been instructed to pretty much keep the move a secret, with no public announcements, and to simply tell customers and partners the tech giant has "discontinued development of HPE OpenSDN" if they ask what's happening.

This is according to an internal memo seen today by The Register , which declares HPE
