What is SSH?
Secure Shell or SSH is a network protocol that allows data to be exchanged using a secure channel between two networked devices. SSH was designed as a replacement for Telnet and other insecure remote shells, which send information, notably passwords, in plaintext, leaving them open for interception. The encryption used by SSH provides confidentiality and integrity of data over an insecure network.
Who can use SSH?
Members on our Website Hosting services can use SSH. We recommend that you only use SSH if you already have knowledge of UNIX.
Customers on our Classic hosting plan cannot use SSH.
If you have Website Hosting and would like to use SSH, please contact Cruzio and ask us to activate SSH for your domain.
How do I access my domain through SSH?
Be sure you back up your website before making any changes you can not easily recover from.
In order to view files, you need to use the same FTP login and password as your Administration login and password. You cannot use different FTP and Administration logins and passwords. When logging in, use the following command:
ssh adminlogin@domain.com
…replacing adminlogin with your administration login and domain.com with your domain name. When the server asks for a password, enter your FTP password.
Recommended SSH clients:
Windows: Putty
Mac OS X: Terminal (included in Mac OS X, in the Utilities folder)
