IP Address
192.0.0.192
This value is the Internet Protocol (IP) address of the
LAN/GPIB Gateway. The IP address is a required value and
is used for all IP and TCP/IP communications with the
LAN/GPIB Gateway.
The IP address is represented in dotted decimal notation
(for example,
154.140.222.201
). This number is not
assigned by Agilent. Rather, it is assigned by your designated
Network Administrator. The LAN/GPIB Gateway uses the
default IP address of
192.0.0.192
as a temporary IP
address until you configure a true IP address.
IP Allow List
*
(all allowed)
The IP allow list defines a list of computer systems that are
allowed to communicate with the LAN/GPIB Gateway. When a
computer system attempts to connect to the LAN/GPIB
Gateway, the Gateway checks the IP address of the computer
system requesting the connection against the list of IP
addresses that are allowed access to the LAN/GPIB Gateway.
The IP address(es) of the computer system(s) are represented
in dotted decimal notation, with each IP address separated by
a blank space. The maximum length of the allow list is 125
characters. Not specifying an allow list or specifying an allow
list value of
*
(the asterisk wild card character) allows
connections from all computer systems on the network.
An example IP allow list entry follows that lists the specific
IP addresses of two computer systems that are allowed to
communicate with the LAN/GPIB Gateway:
allow: 156.140.34.2 192.54.24.5
You can also use the asterisk wild card character (
*
) to
signify all IP addresses. For example, either of the following
entries allow all computer systems with IP addresses starting
with
156.1
40:
allow: 156.140.*.*
or
allow: 156.140.*
In addition, you can use a dash character (
-
) between
numbers to signify a range of IP addresses. For example:
allow: 156.140.34-48.2 192.54.24-37.*
