Recent Thoughts About The Edge of My Network
In recent weeks I’ve been accumulating some thoughts about the edge of networks, and the edge of my home office network in particular.
This all started last month where there was an Ars Technica article describing how someone found a backdoor that allowed an evil-doer to gain admin access to a common consumer combination DSL Modem/router/Wifi AP. The author initially proved the exploit by hacking his Linksys WAG200G wireless gateway.
The article describes how he published the script used to run the exploit. That allowed others to try the exploit against various makes/models of consumer hardware. It thus came to light that the same trick works against various products from Linksys and Netgear, amongst others.
Selecting hardware appropriate for a particular Asterisk installation has been a topic of discussion ever since the emergence of Asterisk. This typically centers around choosing hardware to handle n users or x concurrent calls. Often the focus is on how to scale up to the greatest number of users for a given server. However, there can be different but related considerations as we consider ever smaller applications.
