Fwd: Intel's Management Technology is indeed vulnerable

by Douglas Ray

Firmware remote vulnerability in Intel business products -------- Forwarded Message -------- Subject: Intel's Management Technology is indeed vulnerable Date: Tue, 2 May 2017 19:49:54 +0200 (CEST) From: I love OpenBSD <lampshade(a)poczta.fm> To: misc(a)openbsd.org INTEL-SA-00075 There is an escalation of privilege vulnerability in Intel® Active Management Technology (AMT), Intel® Standard Manageability (ISM), and Intel® Small Business Technology versions firmware versions 6.x, 7.x, 8.x 9.x, 10.x, 11.0, 11.5, and 11.6 that can allow an unprivileged attacker to gain control of the manageability features provided by these products.

Uniti wireless

by Russell Coker

https://unitiwireless.com/ I just got a connection with Uniti wireless. It's only been running for a few hours but it seems good and it's delivering the advertised speed for upload (576KB/s is 4.6Mb/s and a good approximation to the advertised 5Mb). For download I've got 1.2MB/s from the US which is 9.8MB/s, that's quite a bit less than the advertised 25MB/s but still a reasonable speed and a lot faster than my ADSL, I haven't yet tested what speed I can get with multiple downloads at the same time. For comparison I can only get 800KB/s when downloading from Internode servers via ADSL. My ADSL connection is giving an average ping time of 46ms to my server in Melbourne and a best ping time of 33ms. Uniti is giving an average of 14ms and best of 9ms. I don't know how much of that is due to low Uniti ping times and how much is due to connectivity issues where my server is located. It could be that the company hosting my server is connected to Uniti or a company that peers with them. As Uniti runs everything it's all their issue so if something breaks and you don't have the thing of your ISP calling Telstra and Telstra taking their time to fix it. Having recently gone through this I wanted to get away from it in future. https://unitiwireless.com/plans/business-plans/ The above link is for their business plans that are about $30 per month more expensive than the home plans. The business plans all come with a static IP address. I'll probably recommend them to my clients. I chose a home plan for my home, but I know some of you like having a static IP at home and might want to pay an extra $30 per month for it (which is still cheaper than Internode ADSL). -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

Maximum optical-fibre data transfer rates was Re: NBN Cabling responsibilities and CSG

It seems to me part of the problem has been that optical-fibre has always been compared with; alternatives like ADSL over copper, cell-phone wireless on the basis of current data transfer rates, which are good, but not 'disruptive' ie around 100Mb/s. The message which NBN failed to convey, was that fibre has vastly more potential. They should have been marketing that potential, so that politicians like Malcom Turnbull, who regardless of his financial prowess is a technology, dumb-cluck; got the message. For example it took me little time to find : "Earlier this year, global telecoms company Alcatel-Lucent claims to have set a new fibre optic world record with an impressive 31 Tbit/s data transfer over a single fibre cable, overtaking the previous record of 26 Tbit/s set by The Karlsruhe Institute of Technology (KIT) in May 2011, by a team of German, UK and Swiss scientists." at :https://www.warwicknet.com/blog/how-fast-can-fibre-optic-go Now this seems to be a more modern fibre-optic cable from that the NBN is laying, but we should have heard about potential data-tranfere rates (DTR) for the cable the NBN is laying, if they had any imagination. Just off the top of my head I would expect cell-phone DTR to be tied to the frequency of the carrier wave but the frequency of that wave sets the cell size. So to double the cell-phone DTR you need a technology that doubles the frequency and in consequence halves the cell size and quadruples the number of towers. Where as for NBN fibre (up to some limit), the DTR can be increased by orders of magnitude; without costs other than the sending and recieving technology. regards Rohan McLeod

Regards last nights meeting, my presentation

by David Turk

For all that saw my phone pin, I have sent a global MIB style mind wipe, so by now you're wondering why the heck I'm telling you this. Rest assured you still should remember friends and family, however if you don't I defer to... Did you read the terms and conditions of my presentation? No, well Southpark has this message for you! https://youtu.be/FZ23kosLFec
