Network Access

There are 3 main network services for you to interact with OpenDSP:

• SSH
• VNC
• Samba File Share

Some networks with DHCP integrated with DNS services can act as DDNS to dinamicly setup the correct ip address grabbed by opendsp to respond to the host name opendsp.

$ ping opendsp

So if for any reason when you connect your raspberry to your network via ethernet cable and you could not ping opendsp host is because your network are not able to do DDNS. Instead, you need to grab the IP Address of your machine by booting connected on a hdmi display and check on the top bar of interface for the IP.

There are a DHCP client listenning on ethernet interface that will catch an IP address dinamicly. If he could not find any DHCP server on his way, it will fallback to the 192.168.2.100/16 address.

All the network services are accessed using the same user and their share the same password credentials:

Credentials

• Username: opendsp (default)
• Password: opendspd (default)

SSH

Secure Shell - SSH is a cryptographic network protocol for operating network services securely over an unsecured network.[1] Typical applications include remote command-line, login, and remote command execution, but any network service can be secured with SSH.

There are many ways to connect via SSH:

• Windows: Putty
• Linux and Mac:

you@your-computer:~$ ssh opendsp@opendsp  

VNC

Virtual Network Computing - VNC is a graphical desktop-sharing system that uses the Remote Frame Buffer protocol (RFB) to remotely control another computer. It transmits the keyboard and mouse events from one computer to another, relaying the graphical-screen updates back in the other direction, over a network.

There are many SFTP programs out there:

• Windows: TightVNC
• Mac: TigerVNC
• Linux: Remmina

This is a network accessible display, used as a way to free up the Native display in case will needed it for projections or presentations.

If you need help to find your OpenDSP on the network please check Network page.

You can also access the GUI interface from different devices, you mobile phone, a tablet, smart tv, laptop or a PC.

By default opendsp boots with this virtual display on. But you can tweek the config to turn it off by default if you dont need it - it helps to avoid cpu consumption waste.

Web Virtual Display

In case you don't have a VNC client, or don't want to download and install one, you can access via web using noVNC integrated into OpenDSP by default. Just open you web browser and follow the your OpenDSP ip address or network name:

http://opendsp

Samba File Share

Samba is a software suite that allows you to access file systems over the network. Naturally both your PC and Pi will need to be connected to the same network via Ethernet or Wifi in order to successfully transfer your files.

• if on windows type \\OPENDSP into the computer folder. You can also replace OPENDSP with your OpenDSP IP address

• if on MAC OS X open finder, select "Go" menu and "Connect to Server". Type smb://opendsp and hit "Connect".
