chnamsv Command

Purpose

Changes TCP/IP-based name service configuration on a host.

Syntax

chnamsv [ -a"Attribute=Value ..." | -A FileName ]

Description

The chnamsv high-level command changes a TCP/IP-based name service configuration on a host. The command changes the /etc/resolv.conf file only. The command does not change the name server database.

If you change the name service configuration for a client, the chnamsv command calls the namerslv low-level command to change the resolv.conf configuration file appropriately.

You can use the Web-based System Manager Network application (wsm network fast path) run this command. You could also use the System Management Interface Tool (SMIT) smit namerslv fast path to run this command.

Flags

-A FileName

Specifies name of file containing the named server initialization information.

-a"Attribute=Value..."

Specifies a list of attributes and their corresponding values to be used for updating the named server initialization files in the database.

Attributes can be either of the following:

domain: The domain name of the changed named server

nameserver: The Internet address of the changed name server

Examples

To update the named server initialization files, enter the command in the following format:
```
chnamsv   -a"domain=austin.century.com   nameserver=192.9.200.1"
```
In this example the domain name and name server address are updated. The previous domain and name server are overwritten.
To update name server initialization files according to information in another file, enter the command in the following format:
```
chnamsv   -A   namsv.file
```
In this example, the file that contains the updated information is namsv.file.

Files

/etc/resolv.conf

Contains DOMAIN name server information for local resolver routines.
