Navigating Linux and Using SSH


Using Linux With SSH

When you have root access to your Linux hosting account, you have so many extra features that are not available with shared hosting. One of the major features is SSH access with a tool like Putty. With SSH acccess you can literally connect fromm any computer on the Internet and do whatever you want to your website. You can create, edit and delete files, reboot the server, have acomplete access to all mysql databases, and much much more.

Knowing how to navigate at the Linux root can allow you to work on a website with no extra tools. Unlike a typical pc where you need FTP software and an editor, using SSH can be your final safety net if you need to use that. Imagine going on vacation in Cancun and you lose your laptop, or it fails. If you can access your Linux server wuth SSH, you can be back to work at the nearest Internet connection.
