Chapter 11 Management System Setup

Console and Telnet Setup

Settings on the Console/Telnet Page

The Console/Telnet Setup page contains the following settings:

•Baud Rate—The rate of data transmission expressed in bits per second. Select a baud rate from 110 to 115,200, depending on the capability of the computer you use to open the access point management system.

•Parity—An error-detecting process based on the addition of a parity bit to make the total number of bits Odd or Even. The default setting, None, uses no parity bit.

•Data Bits—The default setting is 8.

•Stop Bits—The default setting is 1.

•Flow Control—Defines the way that information is sent between pieces of equipment to prevent loss of data when too much information arrives at the same time on one device. The default setting is None.

•Terminal Type—The preferred setting is ANSI, which offers graphic features such as reverse video buttons and underlined links. Not all terminal emulators support ANSI, so the default setting is Teletype.

•Columns—Defines the width of the terminal emulator display within the range of 64 characters to 132 characters. Adjust the value to get the optimum display for your terminal emulator.

•Lines—Defines the height of the terminal emulator display within the range of 16 characters to 50 characters. Adjust the value to get the optimum display for your terminal emulator.

•Enable Telnet—The default setting is Yes. Select No to prevent Telnet access to the management system.

Using Secure Shell

Secure Shell (SSH) is a program that provides a cryptographically secure alternative to or replacement for Telnet that is considered the standard protocol for remote logins. SSH runs in the Application Layer of the TCP/IP stack. SSH provides a secure connection over the Internet providing strong user authentication. SSH protects the privacy of transmitted data (such as passwords, binary data, and administrative commands) by encrypting it.

SSH clients make SSH relatively easy to use and are available on most computers including those that run Windows or a type of UNIX. SSH clients are also available on some hand-held devices.

SSH on the access point is enabled by default. When user manager is enabled, SSH uses the same usernames and passwords established by the user manager.

Newer computers have the SSH client installed. If your computer does not have the SSH client installed, you must procure and install it before you can proceed. You can download the latest SSH client from the following site:

http://ssh.com/

After you have downloaded and installed the client on your computer, make sure you can browse to the access point. Then launch your your SSH client and make the connection to the access point through it.
