If the
console server
has been configured with distributed Nagios monitoring enabled, then you will also be presented with Nagios Settings
options to enable nominated services on the Host to be monitored (refer to
Chapter 10—Nagios Integration
).
Click Apply. This will create the new Host and also create a new Managed Device (with the same name).
5.5 Trusted Networks
The Trusted Networks facility gives you an option to nominate specific IP addresses where users (
Administrators
and
Users
) must be located
to access
console server
serial ports.
Select Serial & Network: Trusted Networks. To add a new trusted network, select Add Rule.
Figure 5-18. Trusted networks screen.
Select the Accessible Port(s) that the new rule is to be applied to.
Then, enter the Network Address of the subnet to be permitted access.
Then, specify the range of addresses that are to be permitted by entering a Network Mask for that permitted IP range,
for example:
To permit all the users located with a particular Class C network (for example, 204.15.5.0) connection to the nominated port then you would
add the following Trusted Network New Rule:
Network Address
204.15.5.0
Network Mask
255.255.255.0
If you want to permit only the one user who is located at a specific IP address (for example, 204.15.5.13 say) to connect:
Network Address
204.15.5.0
Network Mask
255.255.255.255
If, however, you want to allow all the users operating from within a specific range of IP addresses (for example, any of the thirty addresses
from 204.15.5.129 to 204.15.5.158) to be permitted connection to the nominated port:
Host /Subnet Address
204.15.5.128
Subnet Mask
255.255.255.224
Click Apply.
.
NOTE: The above Trusted Networks will limit
Users
and
Administrators
access to the console serial ports. They do not restrict access to the
console server
itself or to attached hosts. To change the default settings for this access, you will to need to edit the
IPtables
rules
as described in
Chapter 15—Advanced Configuration.
