Figure 3-3. Typical NIPR/S Output Using Telnet
The “+” indicates the IP has been added to the list. A “-“ would indicate the IP has been
removed from the list. This would occur, for example, if the communication link to that node
was removed due to a power shutdown or other disruption.
9.3 Accessing Nodes Locally
Nodes can be accessed locally through the serial link. The required hardware is as follows:
• Terminal with serial interface and terminal software such as Tera-Term Pro or
Hyperlink.
• RS-232 cable 9 pin D shell male to male type.
• Adapter for the Digivance CXD CPU low profile I/O connector (DB-9F to RJ-11).
Once the link is made, run the terminal software. If a login prompt is not already available in
the terminal window, hit enter a few times to bring it up. Then follow a normal login
procedure.
9.4 Accessing Nodes via TCP/IP
To perform some installation maintenance activities, the network operator will need to log into
Digivance CXD nodes. Each node runs a daemon for Telnet, File Transfer Protocol (FTP), and
Virtual Network Connections (VNC). Depending on the LAN’s DNS configuration, a user
may or may not be able to use hostnames (instead of literal IP addresses) when accessing
Digivance CXD nodes. Nodes can always be accessed by IP address. The three access types
are available for Windows and Unix strains.
There are two default user accounts that come standard in the Digivance CXD network. The
“operator” account has access to the Digivance CXD binaries and is used for regular
maintenance. The “root” account has full access privileges to the entire file system. In
addition, the “operator” account has “sudo” privileges, which may be modified by the network
operator to tailor operator access. To learn more about “sudo”, log onto any Linux operating
system and type “man sudo” at the prompt. Note that, among other privileges, a “root” user
can create more user accounts on each node.
