Even if it is too late when someone else logs in as root on your server, it is good to know that NOW is the time to get working on your security.

To setup email notification, login to your server as root.
Edit .bashrc

editor .bashrc

add the following line at the end, changing “ServerName” to the hostname of your server and “email@thisaddress.com” to your own email address.

echo 'ALERT - Root Shell Access (ServerName) on:' `date` `who` | mail -s "Alert: Root Access from `who | cut -d"(" -f2 | cut -d")" -f1`" email@thisaddress.com

!NOTE! - Take notice of the ` in the code block. Sometimes when copying code from a webpage, these small characters will mess up when pasted.

Save and exit your .bashrc.

Next time someone, hopefully you, logs on as root, you will get an email about this.

This can be done for any user, you only have to make sure that the user can email out from your server.

Which one is your favourite? something similar to putty?

I am using Cyberduck, was wondering if there is any better alternatives?

[Guide] Linking VS Code to a VPS file system

Started a new blog with technical articles about linux, servers etc & I reckon the initial post might be of interest to you guys: You can hook a fullblown IDE - Visual Studio Code - into a VPS remotely via SSH.

Why do you need this in your life? Because it's a text editor on steroids with endless extensions available for docker, yaml, python etc plus all the creature comforts of a IDE.

e.g. Docker extension

Step by step on how to achieve this magic:

SSH Tunneling on MrVM NAT VPS Continuation from old forum

milkboy — Tue, 19 Nov 2019 08:29:15 +0000

Continuation of this forum post

TL;DR I want to reverse ssh tunnel port on an IPv4 assigned port.
But all local internal IP port is closed ( except SSH port).
i forwarded PC FTP port to any port.
On localhost (127.0.0.1:any-port) can connect, port scanning shows opened.
On Internal IP (172.1ww.xx.yy:any-port). connection refused, port scanning shows closed.

I port forward to my assign ports. still no dice.

any ideas what i need to do?
