SSH
From Axentra
SSH is short for Secure SHell, and is a protocol for connecting remotely to another computer's command prompt. Your Axentra Server can allow SSH access, although it is disabled by default.

Uses
- The most basic use of SSH is, as mentioned, to access your Axentra Server's command prompt.
- The Axentra Sync software uses SSH to securely and quickly transfer data.
- The SFTP (Secure FTP) protocol uses SSH.
Warning
SSH access to your Server is only as secure as the weakest password on your Server. Never use obvious passwords for your accounts; for example, don't give your "admin" account a password of "admin". If you do not use SSH on your Server, you should turn it off.
Many malicious crackers run programs to attack remote computers on the internet via SSH. These programs will try thousands of username/password combinations every second until they are able to break in. Even if they don't get root access, they can still use your Server to start attacking other computers on the Internet.
Using SSH
Enabling SSH
Your Axentra Server has its SSH access disabled by default. To enable it, you will need to go to the Network Services screen in the admin area and turn ON "Secure shell access (ssh)". Be sure to click Apply or your change won't be saved.
Windows
You will need to download an SSH client program. Axentra suggests the program PuTTY, available at this address: [1] (http://www.chiark.greenend.org.uk/~sgtatham/putty/)
Once you have downloaded your client, run it. Enter your Axentra Server's domain name where it asks for your host name, and be sure to specify a SSH connection; it should be using port 22. (In PuTTY, there is an SSH radio button.) If it asks you for your username and password as well, enter them where prompted.
When you click Connect, you will probably see a key warning. If you are sure you've accessed the right Server, use the option to save the key to your client's record and continue connecting. Enter your username and password when prompted. Once you have successfully signed in via SSH, you will be shown your Server's command prompt.
Mac OS X
Open a new Finder window, and go to the Applications folder, then the Utilities folder. Run the Terminal program. Proceed with the Linux instructions found below.
Linux
Open a new terminal window. Type in the command ssh username@domainname, where username is your username on your Server, and domainname is the domain name of your Server. If this is your first time using SSH, you will see a key warning; type 'yes' to proceed. Then type your password, and you will be taken to your Server's command prompt.
