Tutorials and How-tos/Access Server via SSH
As with any Linux-based server, you can manage Bubba by establishing an SSH connection to it from another machine (e.g., your netbook or desktop computer). Bubba comes with an SSH server installed and enabled by default, so the only thing you need to do is to enable an SSH connection for a specific user account. To do this, switch to the Administration interface, navigate to the Users section, and press the Edit button next to the desired user. Tick the Shell login check box, and press Update button.
Next, you need to install an SSH client on your machine. If you're running Windows, you might want to give PuTTY or [KiTTY] a try. Linux users don't have to install anything -- you can establish an SSH connection from the terminal.
To establish an SSH connection to Bubba using PyTTY, launch it and enter the IP address of your Bubba server in the Host Name field. Select the SSH option in the Connection type section and press Open. Enter then your user name and password.
On Linux, launch terminal and use the following command to establish an SSH connection to the server (replace USER with your actual user name and IPADDRESS with the IP address of the Bubba server):
ssh USER@IPADDRESS
Logged in via ssh
Now you have a prompt in the Linux shell, with user privileges. You may need root privileges to access some files, to get that, type su and use excito as password. Again, note that this gives full access to the entire file system, you now have the power to mess the entire installation up, requiring a full re-install. Be careful.
Examples
Here are some basic examples.
To edit the Debian sources file, type:
nano /etc/apt/sources.list
To view the mail error messages, type:
cat /var/log/mail.err
WinSCP
For windows users that are a bit uncomfortable with navigating in the SSH console and dealing with the various Linux commands the WinSCP application is a killer.
It provides intuitive tree-navigation and comes with internal text editor.
