If you are setting up a crypto 3-DNS Controller that needs to communicate with non-crypto 3-DNS Controllers, you must enable the rsh and rcp tools on the crypto 3-DNS Controller. These are the standard communication and copying tools that non-crypto 3-DNS Controllers, BIG-IP Controllers, and EDGE-FX Caches use.
To enable RSH on a crypto 3-DNS Controller
Run the config_rshd script from the command line utility. The config_rshd script performs several essential steps to enable access for rsh and rcp. We strongly recommend that you use the script rather than doing this manually.
The type of system you have determines the options you have for remote command line administration:
If you are working with a crypto 3-DNS Controller, you can access the Mindterm SSH client through the web-based Configuration utility.
If you want to use a serial terminal (in addition to a standard console) with the 3-DNS Controller, you need only ensure that the serial terminal settings are as follows:
You can configure the 3-DNS Controller to send email notifications to you, or to other administrators, using the Sendmail utility. The 3-DNS Controller includes a sample Sendmail configuration file that you can use to start with, but you must customize the Sendmail setup for your network environment before you can use it.
Before you begin setting up Sendmail, you may need to look up the name of the mail exchanger for your domain. If you already know the name of the mail exchanger, refer to Setting up Sendmail, on page 4-3 , for details about setting up the sendmail daemon itself.
You can use the nslookup command on any workstation that is configured for lookup. Once you find the primary IP address for your domain, you can find the mail exchanger for your domain.
To find the mail exchanger for your domain
Default Server: <server name>
The returned information includes the name of the mail exchanger. For example, the sample information shown in Figure 4.1 lists bigip.net as the preferred mail exchanger.
bigip.net preference = 10, mail exchanger = mail.domain.com
bigip.net nameserver = ns1.bigip.net
bigip.net nameserver = ns2.bigip.net
bigip.net internet address = 192.168.112.1
ns1.bigip.net internet address = 192.168.112.2
ns2.bigip.net internet address = 192.168.112.3
When you set up Sendmail, you must edit three configuration files. Since the 3-DNS Controller does not accept email messages, you can use the crontab utility to purge unsent or returned messages and send them to yourself or another administrator.
