To the members of the MIT community:
We are writing to inform you of plans to upgrade the MIT campus network, and in particular to upgrade MIT to the next generation of Internet addressing. (Please note that no action is required on your part.)
Machines on the Internet are identified by addresses. The current addressing scheme, called IPv4, was specified around 1980, and allowed for about 4 billion addresses. That seemed enough at the time, which was before local area networks, personal computers and the like, but the Internet research community recognized around 1990 that this supply of addresses was inadequate, and put in place a plan to replace the IPv4 addresses with a new address format, called IPv6. IPv6 uses a 128-bit address scheme and is capable of 340 undecillion addresses (340 times 10^36, or 340 trillion trillion trillion possible IP addresses). This stock of addresses allows great flexibility in how addresses are assigned to hosts, for example allowing every host to use a range of addresses to
#It's not directly mentioned in the documentation on how to do this, so here you go. This command will tunnel everything including DNS: | |

Starting with 1.12 in July 2016, Docker Swarm Mode is a built-in solution with built-in key/value store. Easier to get started, and fewer ports to configure.
ℹ️ Please note this research is from 2016 when Opera has first added their browser "VPN", even before the "Chinese deal" was closed. They have since introduced some real VPN apps but this below is not about them.
🕵️ Some folks also like to use this article to show a proof that the Opera browser is a spyware or that Opera sells all your data to 3rd parties or something like that. This article here doesn't say anything like that.
When setting up (that's immediately when user enables it in settings) Opera VPN sends few API requests to https://api.surfeasy.com to obtain credentials and proxy IPs, see below, also see The Oprah Proxy.
The browser then talks to a proxy de0.opera-proxy.net
(when VPN location is set to Germany), it's IP address can only be resolved from within Opera when VPN is on, it's 185.108.219.42
(or similar, see below). It's an HTTP/S proxy which requires auth.

# 1) Install binary as described in no-ip.com's source file (assuming results in /usr/local/bin) | |
# 2) Run sudo /usr/local/bin/noip2 -C to generate configuration file | |
# 3) Copy this file noip2.service to /etc/systemd/system/ | |
# 4) Execute `sudo systemctl daemon-reload` | |
# 5) Execute `sudo systemctl enable noip2` | |
# 6) Execute `sudo systemctl start noip2` |
Make sure the if
value is correct! If doing this over SSH then open a TMUX session first... or else...

NOTE: You might not want to compress the image. It just means you have to uncompress it later to mount it. If you're planning to access the data soon, or frequently, don't compress it.
Save it in the same directory as the compressed image so later on if you decide you want to mount or extract data from the image you can see the partition structure without having to decompress the whole image. There might be some other ways to mount a compressed image.
