SSH Into Docker Container
Secure Shell (SSH) is a widely supported protocol used for remotely making administrative connections to another computer on the network. It enables individuals to access a different computer and run commands through a terminal as if they were physically with the system. SSH is invaluable for system administrators, developers, and network engineers. In this article, we will explore two methods to SSH into Docker containers and discuss best practices for managing SSH within Docker environments.
Accessing Remote Servers with SSH ProxyJump and Jump Hosts
Introduction In practice, it is often impossible to establish a direct SSH connection with a remote server because of different network segmentation policies, firewall limitations, or extremely strict security measures at the organisation’s end. This is where Jump Hosts, commonly referred to as bastion hosts, fill the gap by providing means to connect two or more network segments. Together with SSH’s ProxyJump feature, they offer a secure way to connect to servers that otherwise cannot be reached.
SCP vs SFTP
When it comes to transferring files between systems securely over a network, two commonly used protocols are SCP (Secure Copy Protocol) and SFTP (SSH File Transfer Protocol). While both are built on the foundation of SSH (Secure Shell) and ensure secure data transfers, they differ significantly in functionality, use cases, and efficiency. This article dives into the key differences between SCP and SFTP, their advantages, limitations, and which one you should use depending on your specific requirements.
