SHOW CONFIGURATION

Displays the information in the configuration database. This database, read by the TCP/IP Services startup procedure, holds information to:

Configure the lower-layer protocols, including dynamic routing.
Configure and enable the Internet interfaces.
Configure the services you want enabled when TCP/IP Services starts up.
Configure the BIND resolver.
Configure the BIND server, including the default domain.
Configure SMTP.
Configure SNMP.
Configure TIME.
Map file systems.

Because the SET CONFIGURATION commands do not take effect until the next time TCP/IP Services starts up, the SHOW CONFIGURATION command might not display the current settings for the running software. For example, the information you see from SHOW CONFIGURATION PROTOCOL might differ from the SHOW PROTOCOL /PARAMETERS output.
Related commands: All SET CONFIGURATION commands

Format

SHOW CONFIGURATION { component | ENABLE SERVICE [service] | START ROUTING }

START ROUTING
Required if you do not specify component or ENABLE SERVICE.
Shows whether or not routing is configured to start running by the TCP/IP Services startup procedure.

Qualifiers

/COMMON
Optional. Default: Node specific.
Valid only with SHOW CONFIGURATION ENABLE SERVICE.
Displays the information in the configuration database for the clusterwide enabling or disabling of services.
/FULL
Optional. The default is to give a brief listing of the information.

/OUTPUT=file
Optional. Default: Screen display.
Writes output to the specified file.

SHOW HOST

Displays information from the hosts database.

Related commands: SET HOST

Format

SHOW HOST [ host ]
[ /ADDRESS=IP_address ]
[ /DOMAIN=domain ]
[ /LOCAL ]
[ /OUTPUT=file ]
[ /SERVER=server ]

restrictions

Requires read access to the hosts database.

Parameters

host
Optional. Default: All hosts.
All alias names for the specified host are displayed.

If a host has more than one IP address and you specify the name, all its addresses and aliases are displayed.
If a host has multiple IP addresses and you specify an alias that is defined on multiple IP addresses, only the first IP address and aliases are displayed.
If you do not specifiy the host parameter or if you use a wildcard, all hosts from the local and BIND databases are displayed.
If you use a wildcard to complete a host name, no BIND information is displayed.
If you specify a host, entries are displayed first from the local hosts database, if they exist; otherwise, entries from the BIND database are displayed, if they exist.

Qualifiers

/ADDRESS=IP_address
Optional. Default: None.
Allows you to select a host by IP address.

If a host has more than one IP address and you specify the name, all IP addresses and aliases for the host are displayed.
If a host has multiple IP addresses and you specify an alias that is defined on multiple IP addresses, only the first IP address and aliases are displayed.
Recommended: Use the host parameter instead of this qualifier.

/DOMAIN=domain
Optional. Default: Name service domain.
Domain to be used by the local host. However, the definition of the domain name is valid only during the execution of the current SHOW HOST command. The BIND request is sent to the specified domain.
/LOCAL
Optional.
Limits name-to-address lookups to the local hosts database.
/OUTPUT=file
Optional. Default: Screen display.
Specifies a file for the output of the SHOW HOST command.
/SERVER=server
Optional. Default: Name server list.
BIND servers to be used. The definition of the server name list is valid only during the execution of the current SHOW HOST command. The request is sent to the specified server.
The list is ordered by request preference. For example, the initial request is sent to the first host in the list. If that host is unavailable, the request is sent to the second host in the list, and so on.
You can specify a maximum of three servers.

Examples

TCPIP> SHOW HOST /LOCAL
