Tools For Connecting To PC Systems Remotely

In the world of IT management, sometimes systems engineers need to be able to access computer systems remotely. This could be for a variety of reasons. For instance, an IT admin might need to log into a DHCP server to change its configuration. There are different remote tools for different types of jobs, though.

One of those tools is SSH. SSH stands for secure shell. It's kind of like a VPN where it creates a secure tunnel between two computers. Unlike a VPN, though, it doesn't allow access to the entire network – just the system it's connected to. SSH is commonly used to manage things like switches, routers, or Linux-based systems. SSH is commonly used for the command line environment, though in certain circumstances, it can pass GUIs through it as well.

Another option is remote desktop. The Remote Desktop Protocol is a Microsoft native protocol for remotely connecting from one Windows PC to another. It streams the desktop from the host computer through the network. Though RDP is primarily used for Windows systems, it can also be used with Linux, Mac OS, and Unix systems through 3rd party packages, too. Likewise, there are a variety of RDP client applications available for all major operating systems.

These are only two examples of tools used to remotely connect to other systems. There are many more. IT professionals will need to understand what tools are available and the differences between these tools to use the correct one for the job at hand.
