Settings
Setting
Configuring the
local SNMP server
To Address
Defines the user and domain names of the recipient.
To use email for paging, use the email address for the recipient’s
pager gateway account (for example, myacct100@skytel.com). The
pager gateway generates the page.
Note: The recipient’s pager must be able to use text-based
messaging.
Send via
Lets you choose one of the following methods for routing email:
• Send email through the Environmental Monitoring Unit’s SMTP
server. Selecting Local SMTP Server, which is the recommended
option, ensures that the email is sent before the unit’s 20-second
timeout, and, if necessary, is retried several times.
• Send email directly to the recipient’s remote SMTP server. If you
select the Recipient’s SMTP Server option, and the remote SMTP
server is busy, the timeout may prevent some email from being sent,
With this option, the management card tries to send the email only
once.
When the recipient uses the Environmental Monitoring Unit’s SMTP
server, this setting has no effect.
Email
Generation
Enables (by default) or disables sending email to the defined
recipient.
When you select the Local SNMP Server option for the Send via setting,
you must do one of the following:
•
•
Testing Email
Description
Make sure that forwarding is enabled at that server so that the
server can route email to external SMTP servers.
Note: Always see your SMTP-server administrator before
changing the configuration of your SMTP server.
Set up a special email account for the Environmental Monitoring
Unit. This account then forwards the Email to an external email
account.
In the Web interface, use the Email Test option to send a test email
message to a configured recipient.

Configuring and Using Email Notification
Configuring SMTP and DNS Settings
Requirements for
using SMTP
To use the Simple Mail Transfer Protocol (SMTP) to send email when an
event occurs, you must define the following settings:
•
•
•
The IP address of the Domain Name Service (DNS) server.
The DNS name of the SMTP server and the From Address
settings for SMTP.
The email addresses for a maximum of four recipients.
Note: To page an email recipient who uses a text-based pager
gateway, see the description of the To Address setting
in Settings on page 21.
DNS server
To enable the Environmental Monitoring Unit to send email messages,
you must use the TCP/IP & DNS option (Web interface) or DNS option
(Control Console) in the Network menu to identify the Domain Name
Service (DNS) server by its IP address.
If the unit does not receive a response from the DNS server within five
seconds, email cannot be sent. Therefore, use a DNS server on the
same segment as the unit or on a nearby segment (but not across a
WAN).
After you define the DNS server’s IP address, verify that DNS is working
correctly by entering the DNS name of a computer on your network to
obtain the IP address for that DNS name.
SMTP settings
The Email option in the Network menu accesses the following SMTP
settings:
Setting
Description
SMTP Server
The DNS name of the SMTP server.
From Address
The contents of the From field in the email messages sent by
the Environmental Monitoring Unit.

Security Features

security features
As a network device that passes information across the network, the
Environmental Monitoring Unit is subject to the same exposure as
other devices on the network.
Use the information in this section to plan and implement the security
features appropriate for your environment.
Port assignments
If a Telnet, FTP, or Web server uses a non-standard port, a user must
specify the port when using the client interface, such as a Web
browser. The non-standard port address becomes an extra
“password,” hiding the server to provide an additional level of security.
The TCP ports for which the Telnet, FTP, and Web servers listen are
initially set at the standard “well known ports” for the protocols.To hide
the interfaces, use any port numbers from 5000 to 65535.
For an example of how to access a client interface for which the port is
non-standard, see Access to the Web interface on page 3.
User names,
passwords,
community names
All user names, passwords, and community names for SNMP are
transferred over the network as plain text. A user who is capable of
monitoring the network traffic can determine the user names and
passwords required to log into the Environmental Monitoring Unit’s
Control Console or Web interface as an Administrator or Device
Manager. This security limitation of the protocols affects any device
using Telnet, a Web server, or an SNMP version 1 agent.

Security
Authentication
Authentication
versus encryption
The Environmental Monitoring Unit controls access by providing basic
authentication through user names, passwords, and IP addresses, but
provides no type of encryption. These basic security features are
sufficient for most environments, in which sensitive data is not being
transferred. To ensure that data and communication between the
Environmental Monitoring Unit and the client interfaces, such as Telnet
and the Web browser, cannot be captured, you can provide a greater
level of security by enabling MD5 authentication for the Web interface.
See MD5 authentication (Web interface) on this page.
MD5
authentication
(Web interface)
The Web interface option for MD5 authentication enables a higher level
of access security than the basic HTTP authentication scheme. The
MD5 scheme is similar to CHAP and PAP remote access protocols.
Enabling MD5 implements the following security features:
•
•
•
The Web server requests a user name and a password phrase
(distinct from the password). The user name and password
phrase are not transmitted over the network, as they are in
basic authentication. Instead, a Java login applet combines the
user name, password phrase, and a unique session challenge
number to calculate an MD5 hash number. Only the hash
number is returned to the server to verify that the user has the
correct login information; MD5 authentication does not reveal
the login information.
In addition to the login authentication, each form post for
configuration or control operations is authenticated with a
unique challenge and hash response.
After the authentication login, subsequent page access is
restricted by IP addresses and a hidden session cookie. (You
must have cookies enabled in your browser.) Pages are
transmitted in their plain-text form, with no encryption.
If you use MD5 authentication, which is available only for the Web
interface, disable the less secure interfaces, including Telnet, FTP, and
SNMP. For SNMP, you can disable write-only access so that read
access and trap facilities are still available. For additional information on
MD5 authentication, see RFC document #1321 at the Web site of the
Internet Engineering Task Force. For CHAP, see RFC document #1994.
Firewalls
Although MD5 authentication provides a much higher level of security
than the plain-text access methods, complete protection from security
breaches is almost impossible to achieve. Well-configured firewalls are
an essential element in an overall security scheme.

The NMS IP filters allow access
from designated IP addresses.
• 159.215.12.1 allows only the
NMS with that IP address to
have access.
• 159.215.12.255 allows
access for any NMS on the
159.215.12 segment.
• 159.215.255.255 allows
access for any NMS on the
159.215 segment.
• 159.255.255.255 allows
access for any NMS on the
159 segment.
• 0.0.0.0 or 255.255.255.255
allows access for any NMS.
Only the Administrator account
has access.
In basic HTTP authentication
mode, the user name and
password are transmitted base64 encoded (with no
encryption). MD5 authentication
mode uses a user name and
password phrase.
