In an ad-hoc network, use encryption to prevent uninvited users from joining the network.
NOTE
SNMP Community Names
The SNMP community name allows management tools using SNMP to display or modify
Access Point parameters remotely. The Access Point supports a read/write community
name and a read-only community name.
By default, the Access Point uses public as the default read/write community name. This
allows any management tool using SNMP to access the Access Point and change
parameters. By changing the read/write community name, users must enter the correct
community name to modify the Access Point parameters.
The read-only community name allows the management tools to view but not change the
Access Point parameters. You can change the read-only name so that users must enter the
correct name before they can view the Access Point parameters.
Console Port
The RoamAbout console port has two security features:
•
You can configure the console port to require a password before users can access the
Installation Menu.
•
You can configure the console port to prevent any management system from using
SNMP to modify the encryption parameters.
Network Protocols
When you install a RoamAbout PC Card in a computer using a Windows operating system,
you may need to install and configure a set of networking protocols. The type of protocols
needed depends on the network operating system used within your LAN environment. The
most common protocols are:
•
IPX/SPX compatible protocols if your networking environment is using the Novell
NetWare network operating system.
•
NetBEUI if you want to use file and print sharing supported by Microsoft Client for
Microsoft Networks.
Broadcast and multicast messages are not encrypted.
