ssh -L localport:localhost:remoteport username@hostip

e.g. ssh -L 9000:localhost:36839 azureuser@52.186.170.39

You can then access the website on your local machine on this url http://localhost:9000

If you need to use a private key file, then do

ssh -i ./path-to-private-key-file -L localport:localhost:remoteport username@hostname

Enable systemd in WSL 2

NOTE: If you have Windows 11 there is now an official way to do this in WSL 2, use it if possible - see MS post here (WINDOWS 11 ONLY)

This guide will enable systemd to run as normal under WSL 2. This will enable services like microk8s, docker and many more to just work during a WSL session. Note: this was tested on Windows 10 Build 2004, running Ubuntu 20.04 LTS in WSL 2.

• To enable systemd under WSL we require a tool called systemd-genie

• Copy the contents of install-sg.sh to a new file /tmp/install-sg.sh:

zentala

function formatBytes(bytes,decimals) {
   if(bytes == 0) return '0 Bytes';
   var k = 1024,
       dm = decimals || 2,
       sizes = ['Bytes', 'KB', 'MB', 'GB', 'TB', 'PB', 'EB', 'ZB', 'YB'],
       i = Math.floor(Math.log(bytes) / Math.log(k));
   return parseFloat((bytes / Math.pow(k, i)).toFixed(dm)) + ' ' + sizes[i];
}

// Usage:

mehedicsit

<?php
Give me one record
$queryFilms = "SELECT filmName, filmDescription FROM movies WHERE filmID = 10";
$resultFilms = $mysqli->query($queryFilms);
$rowFilms = $resultFilms->fetch_assoc();
// then to output
echo "<p>{$rowFilms['filmName']}</p>";
