Glossary
Glossary-2
the IP address of a load host (usually itself), and the name of the download file.
The dumb node needs only know its own hardware address, as this is what the
BOOTP server uses to decide whether it can help the node and what
information to provide.
BOOTP implementations usually have a configuration file (such as
/usr/etc/bootptab) that lists the hardware and IP addresses of BOOTP clients,
as well as the download file they should use. Most TCP/IP hosts can act as
servers if BOOTP replies have been enabled. See your local documentation
(man pages) for specific information.
console
The terminal used to configure the Server at boot time. When the Server first
powers up and cannot access a load file, a console is enabled on Port 1 to let
the manager set up the Server. This console port is the only port that is
operational at boot time. After the Server is running normally, the Server will
send diagnostic and error messages to this port.
See the Set/Define Server Console command for more information.
dialback
A security feature that ensures people do not log into usernames or Server ports
that they shouldn’t have access to. When dialback is enabled on a port, the user
is prompted for a username. If that username is not in the dialback table, the
port is logged out and Server access is denied. If it is in the table, the port is
logged out and the Server sends a command to the serial port (and presumably
the attached modem) to try to reconnect the user. The command is commonly
a modem command used to dial a particular phone number, thus verifying that
the user is accessing the server from the proper place.
DHCP
Dynamic Host Control Protocol. DHCP allows nodes on the network to lease
IP addresses from a DHCP server. If the node has been configured to query a
DHCP server, the node will receive a temporary IP address each time it boots.
When a node is no longer using the IP address, it goes back into the pool of
available IP addresses for the next query.
domain name
A text name appended to a host name to form a unique host name across
internets. Very loosely, it is a text name corresponding to the network portion
of an IP address. For example, IP address 192.0.1.150 might correspond to host
“alex.ctcorp.com;” if the hostname is “alex,” the domain name is
“ctcorp.com.” The domain name on the Server is used for nameserving, when
a host might be known only by its full name (including domain name).
download
The transfer of a file or information from one network node to another.
Generally it refers to transferring a file from a “big” node, such as a computer,
to a “small” node, such as a terminal server or printer. Because the Server code
is downloaded (as opposed to being stored permanently in the device’s ROM),
the code can be upgraded easily.
Fast Ethernet
High-speed Ethernet. See 100BASE-T.
flash ROM
See ROM.
