Operator's Guide

Where security is a concern - for example, where systems may be left

connected to the internet for any significant period - you may wish to
change the password. In this case, you should also use secure HTTP

to access the web interface rather than the more common http. To do
this, prefix the URL to the device with the https: protocol specifier

rather than http:. For example, if you can access your system as
http://192.168.0.1, you can also use https://192.168.0.1 

and this will prevent your new password from being retrieved by
eavesdroppers.

There is much information available on-line for choosing a strong

password, for example:

http://tinyurl.com/strongpws

.

Selecting “Passwords” from the “Tools” menu takes you to a screen
from which you can change the password used for both command-line

access and for the web interface.

Currently, the only user configured on a CMG-EAM is root. The

password is changed immediately but the built-in web-server can
continue to use the old password for some time after a change. If this

is a problem, the web service can be restarted from the Services page
(see section 13.2.4 on page 181) by clicking the “Restart” button for the

“httpd” service.

To change the password from the command line, issue the command
passwd: You will be prompted twice for the desired new password:

eam2010 ~ # passwd

New password:

Repeat:

Password changed.

eam2010 ~ #

November 2010
