After my article SSH - Launch a terminal on your session without having to authenticate yourself, it was obvious that, next to the ssh and scp commands, I forgot the sftp one.
In this article, we'll explore how to start a SFTP connection to a remote server; from the command line.
In the second section, we'll also learn how to configure the sftp connection to use a proxy server.
Imagine that you regularly need to connect to your Linux server: you need to launch a tool such as Putty, you need to enter your login, password, etc. and carry out various operations before you can access the terminal.
If your password isn't saved in Putty's configuration, you'll have to launch another tool like a password vault; in short, it's annoying.
In this article, we'll look at how to authenticate once and for all on the server using an SSH key.
There are plenty articles on the Internet but I didn't find the one that allowed me, without an impressive amount of trial and error, to find the solution.
So here's another article to add to the long list: how to access a private project stored at Github when creating a Docker image. In other words, the SSH key is not stored in the image. Docker will just use your key when executing the project recovery layer (the one containing the git clone instruction) and will not keep track of the key afterwards.
In a previous article, I've explained how to run a static HTML site in seconds.
The result was a site running on your computer; using http. Let's go one step further and learn how to configure Docker to use https i.e. SSL and encryption.
In this article, you'll learn how to use Apache, nginx and PHP on your machine and be able to start https://localhost.
A few days ago, I've updated my Putty configuration to set the default font-size to 12; no more 10.
Today, by starting Putty, whatever on which server I wish to join, I got the No supported authentication methods available followed by, in my case (server sent: publickey, gssapi-keyex, gssapi-with-mic, keyboard-interactive) fatal error.
I've only understand the origin of the problem by looking at the window caption: Putty tries to connect to a server other than the one I want. Why? And, ah, ok, last time I've modified my settings I was working on that server so, the solution should come from: how can I reset my Putty settings?
Using SSH instead of HTTPS to connect to Github is more secure. Indeed, SSH relies on public-key cryptography. This makes unauthorized access much harder compared to a password, which can be stolen through phishing or brute-force attacks. Also, HTTPS transmits your username and password (encrypted) over the network, which can be intercepted in a Man-in-the-Middle (MITM) attack. SSH doesn't transmit passwords after the initial setup.
Let's see how to add a SSH key and, from now, being able to work with Github like using the git@ protocol with git clone.
