![]() ![]() For experienced engineers, though, that’s not that big of a deal, it’s just that people need to get used to such things before working with them. No GUI – the work with data over SSH is pretty dull, really: it’s all commands and issuing technical instructions to a server without any interface, and for some, not having a clear and concise GUI is a really big turn-off. Sounds like a hassle, doesn’t it? Now imagine that you didn’t have any technical knowledge in the first place – how complex would it all be? Before embarking on their SSH journey, people must know how to generate SSH keys, then copy the SSH keys over to the server they’re going to access, know what SSH key they’re going to use to access a server, what server are they going to access, and does the server support SSH connections in the first place. Technical knowledge – the first and foremost problem of SSH is that it requires quite a bit of technical knowledge to operate and to get to work correctly. In other words, the concept of SSH is secure communication, but SSH also has a couple of downsides that must be considered: Security and SSH – the DownsidesĪs you might have understood, the core concept of SSH is the communication of two servers in an encrypted manner. However SSH tunnels are being used, their core premise remains the same – they provide people with a way to securely access their most precious data: a simple image would illustrate the concept of an SSH tunnel (8080, 22, and 80 are ports) – in this case, server #1 reaches the server #3 through server #2 (note that the port with which server #2 is accessed is no longer 8080 or 80 – it’s 22 meaning it has been accessed through SSH): Many companies use SSH, and the use case of SSH tunnels varies from company to company – some companies use SSH to access internal data to support their marketing, software engineering, security, or other efforts, some use SSH tunnels for interviews to grant people access to remote Amazon AWS servers for them to work with data to complete a task and provide a report on what they‘ve accomplished, some use them for other tasks. In simple terms, a SSH tunnel is a method of working with data over SSH – short for a Secure Socket Shell (also sometimes called Secure Shell.) SSH is a way to securely access a server over an unsecured network. Whatever the case, SSH tunneling is a method of working with data remotely via an SSH connection – and SSH is also commonly used as a method to create secure tunnels between different servers. Many developers know SSH tunnels inside out – many times they’re a prerequisite to working remotely, and sometimes they’re a necessity to complete work with websites, applications, or databases supporting them. In most cases, SSH is fast, easy to setup, and easy to use, but it’s not without it’s drawbacks. SSH tunnels are a well-known measure to securely forward connections to a remote machine. ![]()
