Using MSYS2 with Visual Studio Code is extremely easy now thanks to the Shell Launcher extension by Tyriar.

First, install the extension and reload Visual Studio Code.

Then, open the settings.json to edit your settings.

Add the field shellLauncher.shells.windows. I recommend using autocompletion here so that all the default shells are added.

You should having something like this now:

I have resolved this problem by setting terminal.integrated.env.windows

Here is the setting:

"terminal.integrated.shell.windows": "C:\\Program Files\\Git\\bin\\bash.exe",
"terminal.integrated.env.windows": {
    "LANG": "C.UTF-8"
}

  Download MSYS2 from this page (choose 32 or 64-bit according to what version of Windows you are going to use it on, not what kind of executables you want to build, both versions can build both 32 and 64-bit binaries).
  After the install completes, click on the newly created "MSYS2 Shell" option under either MSYS2 64-bit or MSYS2 32-bit in the Start menu. Update MSYS2 according to the wiki (although I just do a pacman -Syu, ignore all errors and close the window and open a new one, this is not recommended and you should do what the wiki page says).
Install a toolchain
a) for 32-bit:
  pacman -S mingw-w64-i686-gcc
b) for 64-bit:
  pacman -S mingw-w64-x86_64-gcc

Исходные данные: роутер имеет адрес 192.168.1.1, tor и i2pd подняты на 192.168.1.10 (если роутер достаточно мощный, можно поднять их прямо на нём, соответственно скорректировав адреса)

В LEDE для загрузки списка заблокированных доменов проще всего использовать поставляемую по умолчанию утилиту uclient-fetch. Необходимо лишь добавить ей поддержку SSL:

opkg update
opkg install libustream-mbedtls

Впрочем, вы можете использовать wget или curl, если предпочитаете. Особенности wget см. ниже.

How to automatically start ssh server on boot on Windows Subsystem for Linux

Microsoft partnered with Canonical to create Bash on Ubuntu on Windows, running through a technology called the Windows Subsystem for Linux. Below are instructions on how to set up the ssh server to run automatically at boot.

1. Edit the /etc/ssh/sshd_config file by running the command sudo vi /etc/ssh/sshd_config and do the following
   1. Change Port to 2222 (or any other port above 1000)
   2. Change PasswordAuthentication to yes. This can be changed back to no if ssh keys are setup.
2. Restart the ssh server:
   • sudo service ssh --full-restart
3. With this setup, the ssh server must be turned on every time you run Bash on Ubuntu on Windows, as by default it is off. Use this command to turn it on:
