Role of a DNS Server
As Internet communications are carried out on the basis of IP addresses,
appropriate DNS server settings are required for mapping domain names
(host names) to corresponding IP addresses, or the Dominion PX may fail
to connect to the given host.
Therefore, DNS server settings are important for LDAP authentication.
With appropriate DNS settings, the Dominion PX can resolve the LDAP
server's name to an IP address for establishing a connection. If the
SSL
encryption is enabled, the DNS server settings become critical since only
fully qualified domain name can be used for specifying the LDAP server.
For information on LDAP authentication, see Setting Up LDAP
Authentication (on page 128).
Modifying the Network Service Settings
The Dominion PX supports these network communication services:
HTTPS, HTTP, Telnet and SSH.
HTTPS and HTTP enable the access to the web interface, and Telnet and
SSH enable the access to the
command line interface (see " Using the
Command Line Interface " on page 230).
By default, SSH is enabled, Telnet is disabled, and all TCP ports for
supported services are set to standard ports. You can change default
settings if necessary.
Note: Telnet access is disabled by default because it communicates
openly and is thus insecure.
In addition, the Dominion PX also supports the SNMP protocol.
Changing the HTTP(S) Settings
HTTPS uses Secure Sockets Layer (SSL) technology to encrypt all traffic
to and from the Dominion PX device so it is a more secure protocol than
HTTP.
By default, any access to the Dominion PX device via HTTP is
automatically redirected to HTTPS. See
Forcing HTTPS Encryption (on
page 110).
To change the HTTP or HTTPS port settings:
1. Choose Device Settings > Network Services > HTTP. The HTTP
Settings dialog appears.
2. To use a different port for HTTP or HTTPS, type a new port number in
the corresponding field. Valid range is 1 to 65535.
Warning: Different network services cannot share the same TCP port.
