DSL Operators Mailing List?

2018-01-07 Thread Mike Hammett
Is there a good mailing list for DSL operators? A cursory search really only came up with DSL Reports, which is far from what I'm looking for. - Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP

Spectre/Meltdown impact on network devices

Hello, I'm curious to hear the impact on network devices of this new hardware flaws that everybody talk about. Yes, the Meltdown/Spectre flaws. I know that some Arista devices seem to use AMD chips and some say that they might be immune to one of these vulnerability. Still, it's possible to spawn

I have a customer on a ps3, and he can't seem to connect to the psn. Keeps getting the 80710016 error. If there is anyone that can help me troubleshoot this issue, that would be great.

I will be on site with the customer tomorrow to do packet captures. It may be a weak wireless signal(he claims). I also saw such a report, and changed his IP to one of our known good IPs, and the issue persists. We are running over PPPoE, so packet size is diminished from 1500 to 1492. I have DMZed

AFAIK, Meltdown/Spectre require access to some proper programming language and ability to run attacker own code. If underprivileged user can't spawn shell on device or run some python code - i guess you are safe. I guess people need to push support of vendors, for equipment who has programming

Blockchain and Networking

Hi, Do folks on this list see blockchain technology making inroads into the networking? I can see blockchain being used to secure the SDN environment where blockchain will allow encrypted data transfers between nodes (ones hosting different applications, the SDN controller, the data plane devices)
