How to turn anything into a router

https://nbailey.ca/post/router/
Fortunately, you can make a router out of basically anything resembling a computer. I’ve used a linux powered mini-pc as my own router for many years, and have posted a few times before about how to make linux routers and firewalls in that time. It’s been rock solid stable, and the only issue I’ve had over the years was wearing out a $20 mSATA drive. While I use Debian typically, Alpine linux probably works just as well, perhaps better if you’re familiar with it. As long as the device runs Linux well and has a couple USB ports, you’re good to go. Mini-PCs, desktop PCs, SBCs, rackmount servers, old laptops, or purpose built devices will all work.

Cheap, overkill Amiga network adapter - blog.jmp.no

http://jmp.no/blog/cheap-overkill-amiga-network-adapter
Since the Raspberry Pi was just sitting there, and the Amiga lacked (*) a network adapter - why not just connect the dots and get something up and running? I did, and it worked. Here's a quick writeup on what I did - if anyone's interested I can write a more detailed post with all the information I have.

HoRNDIS: USB tethering driver for Mac OS X | Joshua Wise's domain

http://joshuawise.com/horndis
HoRNDIS (pronounce: “horrendous”) is a driver for Mac OS X that allows you to use your Android phone's native USB tethering mode to get Internet access. It is known to work with Mac OS X versions 10.6.8 (Snow Leopard) through 10.9 (Mavericks – see notes below), and has been tested on a wide variety of phones. Although you should be careful with all drivers that you install on your computer, HoRNDIS has been tested at least well enough for the author (and many others) to run full time on their own personal computers.

Stop Sharing Your Files When You Travel

http://www.readwriteweb.com/hack/2011/11/stop-sharing-your-files-when-y.php
I have been on the road a lot in the past several months, and one thing I keep seeing is that folks are over-sharing. I am not talking about putting up those ribald pictures on your Facebook account, or forwarding those questionable email "jokes." But literally sharing your computer's data files across the hotel (and some airports too). Here is what my Mac Finder looks like at a Hilton that I was at earlier in the week (you can see that I am connected to several of my fellow travelers' PCs):

Port Map and TCMPortMapper

http://www.codingmonkeys.de/portmap/index.html
Did you ever feel the urge to map your networking ports using your Airport Basestation or a UPNP router? Did you ever want your application to be reachable from the internet, even in a home networking setup? Don't despair anymore. Port Map and TCMPortMapper are here!

UPnP PortMapper Homepage

http://upnp-portmapper.sourceforge.net
The UPnP PortMapper is an easy to use program that manages the port mappings (port forwarding) of a UPnP enabled internet gateway device (router) in the local network. You can easily view, add and remove port mappings.

Duplicated Virtual Machines Have Same IP Address (View topic) • virtualbox.org

http://forum.virtualbox.org/viewtopic.php?f=8&p=149855
"Ok, that Ubuntu issue is a known problem. It saves the assignment of MAC ethX using an udev rule. Have a look at /etc/udev/rules.d and you will find a file 70-persistent-net.rules there. You can savely remove this file. This file is auto-generated by /lib/udev/rules.d/75-persistent-net-generator.rules. You can remove that file as well. From now on, the guest will no longer store the assignment between the MAC and ethX interface."

SubSpace: Documents

http://sharvil.nanavati.net/projects/subspace/documents.html
"This page contains links to documents that I have written regarding SubSpace and Continuum. Some documents go into the details like offsets of key data structures that I found in a specific executable while others are descriptive, high-level documents. There might even be some documents that don't make much sense. Those were just scrap documents I wrote to keep track of bits of information as I was going through the assembly so they're not formatted for presentation. They make sense to me and if there's enough interest, I could be convinced to clean them up a bit. "

"Lets say you want to use POP from your local machine to a remote machine, but don't have an SSL aware email client. What you can do is to have your machine talk to stunnel on the local machine, who then encrypts the packets and sends them another stunnel running on the remote machine, which forwards them in clear text to the POP server on that machine.

Is a Perfect Storm Forming For Distributed Social Networking?

"Maybe it's better to host your own. That's the thinking coming from a growing number of early technology adopters as service after service goes down, sells out or otherwise frustrates the users who have published their content online only to see the tools they use become broken or less desirable.

Meraki Releases World’s First Solar-Powered WiFi Device : CleanTechnica

http://cleantechnica.com/2008/12/05/meraki-releases-worlds-first-solar-powered-wifi-device
"Yesterday, wireless networking provider Meraki started shipping the world’s first solar-powered WiFi mesh device. Meraki’s groundbreaking energy-independent device is powered by a single solar panel and solar-charged battery. Since the unit requires no grid-derived energy, it can be set up in areas lacking power suppliesWith a price range of $848 to $1,497, Meraki’s set-up isn’t exactly cheap. It is, however, cheaper than most other outdoor wireless network installations. The most expensive item in outdoor wireless networks is often the electrical cabling installation— a step that isn’t necessary for the Meraki unit since it uses a solar-powered battery."

Secret Geek A-Team Hacks Back, Defends Worldwide Web

"Or, for the sheer geeky joy of it, he could reroute all of .com into his laptop, the digital equivalent of channeling the Mississippi into a bathtub. It was a moment hackers around the world dream of—a tool that could give them unimaginable power. But maybe it was best simply to close his laptop and forget it. He could pretend he hadn't just stumbled over a skeleton key to the Net. Life would certainly be less complicated. If he stole money, he'd risk prison. If he told the world, he'd be the messenger of doom, potentially triggering a collapse of Web-based commerce."

Step By Step: Set Up Universal Ad Blocking Through Your Router

http://lifehacker.com/5060053/set-up-universal-ad-blocking-through-your-router
"If you've turned your $60 router into a user-friendly super-router with open-source firmware Tomato, you already know that Tomato can boost your Wi-Fi signal, track bandwidth usage, and set Quality of Service rules with ease. But if you're a big fan of Adblock Plus—the most popular Firefox extension among Lifehacker readers—you can save yourself an extension installation and universally block ads across your entire home network by adding a custom script to your Tomato firmware."

EarthLink IPv6 in the Home

http://www.research.earthlink.net/ipv6
"The firmware rework enables the WRT54G to a) acquire a publicly routeable /64 IPv6 prefix, b) provide IPv6 addresses from that prefix to hosts on the home network, and c) route IPv6 home network traffic to the greater IPv6 Internet."
