    Introduction The DASDEC II is a 2U rack mounted unit built with the latest digital PC computer technology. It is an embedded PC platform. The front of the DASDEC II, pictured below, provides a very simple face for a very sophisticated platform. The DASDEC II exposes the PC motherboard connectors and single PCI slot in the rear of the unit.

A second network interface can also be configured with a static or DHCP address. The second network interface will only be enabled if the correct hardware is installed.
  • Page 31 The primary network interface on the DASDEC II defaults to a static IP address of 192.168.0.200. This is a commonly used, non-public IP address for LAN based appliance hardware. This value is meant to be changed. The default IP netmask is 255.255.0.0. No default DNS or gateway is configured. If the gateway is selected, it defaults to 192.168.0.1.

  • Page 35: Security: Server Network Security Configuration

    DASDEC II's public/private key pair must be "authorized" on the remote platform. Authorization usually is achieved by copying the public key into a file on the remote host. The DASDEC II uses the open source package OpenSSH for SSH features. This package has a file called "authorized_keys2" under /root/.ssh/ to hold the authorized public keys from remote platforms.

    EAS NET operates by sending optional audio, optional text translations, and an EAS event notification file from a DASDEC II to a remote device over a LAN or WAN. There are some differences depending upon the chosen EAS NET protocol. SSH STDIN Only does not offer sending of digital audio WAV files or text translations.
  • Page 94 This is used primarily to provide live EAN/EAT audio from EAS NET send to an EAS NET client device (including another DASDEC II). The stream is not an MPEG transport stream. It is an http audio stream. Remote clients must actively load the URL for the stream in order to play it.
