want to embed as objects in the portal object reference. Typically, in a
redundant system, this list includes the fail-over IP address of the other
3-DNS unit in the redundant system.
This option prompts you to set the portal to use IP addresses instead of DNS
names. If the portal is set to use IP addresses, the 3-DNS Controller does not
have to do a DNS lookup.
In addition to these settings, you can change the following iControl portal
settings:
• The security mode of the portal. You can allow the portal to handle
non-secure requests.
• The name of the portal object reference file.
• The portal PID file name.
Configuring RSH
This option is available only in the menu after you create the initial software
configuration. Use this option to configure the remote shell (rshd) server.
This utility prompts you for an IP address from which administrators may
access the 3-DNS Controller. You can use wildcard characters (*) to include
all addresses from a specific part of the network. This utility also prompts
you to create a support account for access by technical support.
If inetd is not currently configured, this utility configures inetd for the
remote shell server (rshd). If the service port for rsh is closed, this utility
opens the service port to permit rsh connections to the system.
Configuring Telnet
Use this option to configure the Telnet server only on a 3-DNS Controller.
The Setup utility prompts you to configure each service independently. This
allows you to enable Telnet.
The utility prompts you for a configuration address for each service from
which administrators may access the 3-DNS Controller. You can use
wildcard characters (*) to include all addresses from a specific part of the
network. This utility also prompts you to create a support account for access
by technical support.
If inetd is not currently configured, this utility configures inetd for the
requested services. If the ports for Telnet are closed, this utility opens the
ports to permit Telnet connections to the 3-DNS Controller.
Configuring FTP
Use this option to configure FTP on the 3-DNS Controller. The Setup utility
prompts you for an IP address from which administrators may access the
3-DNS Controller with FTP. You can use wildcard characters (*) to include
all addresses from a specific part of the network. This utility also prompts
you to create a support account for access by technical support.
