BIG-IP Controller Configuration Utilities
Introducing the BIG-IP Controller configuration utilities
The BIG-IP Controller includes a number of configuration utilities. These utilities allow you to reconfigure portions of your installation after initial configuration.
The following configuration utilities are available on the BIG-IP Controller:
- config
This utility is also known as the First-Time Boot utility. This utility runs all the other utilities required to configure the BIG-IP Controller, most of the utilities in this list. - config_failover
Use this utility to prepare a new redundant system for the commands that synchronize redundant controllers. - reconfig-httpd
Use this utility to reconfigure the web server on the BIG-IP Controller. - config_telnetd
Use this utility to configure the Telnet and FTP daemons. - config_sshd
Use this utility to configure the SSH daemon. - config_rshd
Use this utility to configure the RSH daemon.
config
Description
This utility starts automatically the first time you boot up a BIG-IP Controller. The config utility, referred to as the First-Time Boot utility, is a wizard that walks you through a brief series of required configuration tasks. These tasks include defining a root password and configuring IP addresses for the interfaces. You can run the First-Time Boot utility to reconfigure a controller.
The First-Time Boot utility is organized into three phases: configure, confirm, and commit. Each phase walks you through a series of screens, presenting the information in the following order:
- Root password
- Host name
- Default route (typically a router's IP address)
- Time zone
- DNS proxying
- Interface settings for the each network interface
- Configuration for BIG-IP Controller redundant systems (fail-over IP address)
- IP address for remote administration
- Remote administration access for vendor support
- Settings for the BIG-IP web server
- Web server administration access for vendor support
When using the config utility, you first configure all of the required information, then you have the opportunity to confirm each individual setting or correct it if necessary, and finally your confirmed settings are committed and saved to the system. Note that the screens you see are tailored to the specific hardware and software configuration that you have.
If you have a stand-alone system, for example, the First-Time Boot utility skips the redundant system screens.
To run the First-Time Boot utility, type in the following command:
config
config_failover
Description
You must run the config_failover script on the second controller in a redundant system in order to share keys with the peer BIG-IP Controller.
The script prompts you for the root password of the other controller in the redundant system. After confirming your input, the config_failover script attempts to access the peer system and configure both systems to communicate with one another. This provides the secure communication channel the controllers use to exchange configuration data when you run the bigpipe configsync option, or use the Config Sync button in the Configuration utility.
To run the config_failover script, type the following command on the command line:
config_failover
reconfig-httpd
Description
Use the reconfig-httpd configuration utility to reconfigure the HTTPD server on a BIG-IP Controller.
This script prompts you for an IP address from which administrators can access the BIG-IP Controller through the BIG-IP web server. 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 the service port for the BIG-IP web server (httpd) is closed, this script automatically opens the service port to permit access to the BIG-IP web server.
To run the BIG-IP web server configuration utility, type the following command:
reconfig-httpd
config_telnetd
Description
Use the config_telnetd configuration script to configure the Telnet and FTP servers on a BIG-IP Controller. The script prompts you to configure each service independently. This allows you to enable Telnet but not FTP, for example.
The script prompts you for a configuration address for each service from which administrators may access the BIG-IP 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 script configures inetd for the requested services. If the ports for Telnet or FTP are closed, this script opens the ports to permit Telnet or FTP connections to the BIG-IP Controller.
To run the Telnet/FTP configuration utility, type in the following command:
config_telnetd
Note: Running config_telnetd again replaces the current configuration.
config_sshd
Description
Use this utility to configure the secure shell server (sshd) on a BIG-IP Controller. This utility prompts you for an IP address from which administrators may access the BIG-IP Controller with SSH. 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 the service port for SSH is closed, this script opens the service port to permit SSH connections to the BIG-IP Controller.
To run the secure shell configuration utility, type in the following command:
config_sshd
Note: Re-running config_sshd again replaces the current configuration.
config_rshd
Description
Use the config_rshd configuration utility to configure the remote shell (rshd) server on a BIG-IP Controller. This utility prompts you for an IP address from which administrators may access the BIG-IP 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 script 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 BIG-IP Controller.
To run the rsh configuration utility, type in the following command:
config_rshd
Note: Running config_rshd again replaces the current configuration.
