Setup CURL for MinGW
# Setup CURL libraries for MinGW
- Install msys2
- Open msys2 shell
- cd curl-x.xx.x folder (cd C:/ ...)
- run configuration command:
./configure --prefix=/usr/local --with-ssl--build=x86_64-w64-mingw32 CPPFLAGS="-I/usr/local/include" LDFLAGS="-L/usr/local/lib"
- build curl:
make install-strip
# gcc example:
gcc curl_test.c -o curl_test -DCURL_STATICLIB -lcurl -I"C:\MinGW\include" -L"C:\MinGW\lib"
Setup dotnet
# Download and install:
https://www.microsoft.com/net/download
# List available project types:
dotnet new
# Create new project:
dotnet new webapi -o AspNetCoreWebTest
# Build
dotnet build
# Run
dotnet .\bin\Debug\netcoreapp2.1\AspNetCoreWebTest.dll
Powershell run linux commands
# Download plink.exe
https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html
# Run commands on linux machine
.\plink root@192.168.1.35 cat /home/root/testfile.txt
# Give a command list to execute on linux machine
# With -m parameter you can give the the ssh server a list of commands, instead of opening a new shell.
# Create command.txt and put linux commands to it
# Run command
.\plink root@192.168.1.35 -i ..\ssh\private.ppk -m "command.txt" -t
# -x enable X11 forwarding
# -X disable X11 forwarding
# -v verbose output
Setup vnc
# New putty connection:
hostname 192.168.10.38
Connection -> Data -> Auto-login username -> root
Connection -> SSH -> Auth -> Private-key -> PUTTYGEN_GENERATED_KEY_HERE
Connection -> SSH -> X11 -> tick 'Enable X11 forwarding'
Sessions -> save
-> Open new ssh connection with Putty
## On linux:
# Install tightvncserver
sudo apt-get install tightvncserver
# Run vncserver ( take a not on what is the vncserver number, it should show up when the command is run)
vncserver
# Set password
# To kill the server
vncserver -kill :# ( #- number is shown when vncserver is started )
## In PUTTY:
# Setup tunneling
Connection -> SSH -> tunnels -> Source port: 5900
Connection -> SSH -> tunnels -> Destination port: localhost:5901 ( last number should be the same number that vncserver showed up when starting it )
Add
Sessions -> save
# Open x11 connection from PUTTY
# Install tightvnc viewer
# Open new vnc connection
-> server: localhost
# This will be on as long as x11 Putty window is open

Check checksum
Check signatures
# Setup on Windows
1. Download gpg4win
2. Check gpg4win signature
certutil -hashfile gpg4win-3.1.7.exe SHA256
certutil -hashfile gpg4win-3.1.7.exe MD5
3. Install gpg4win
4. Refresh environment variables of the command prompt
refreshenv
5. Download the file which we are checking the signatures from:
curl -o https://some_file
6. Download the signature creators public key and import to gpg4win
curl -o some_file.pub
gpg --import some_file.pub
7. Download signature
curl -o some_file.sig
8. Finally check the signature
gpg --verify file_to_check.zip.sig file_to_check.zip
9. Verify the output:
gpg: Signature made 09/06/18 00:01:57 FLE Summer Time
gpg: using RSA key F48B339EE7ADC266
gpg: Good signature from "Göran Krampe (getcanoe.io) <goran.krampe@gmail.com>" [unknown]
gpg: WARNING: This key is not certified with a trusted signature!
