System Management Guide: Communications and Networks

Configuring TCP/IP

If you installed the Transmission Control Protocol/Internet Protocol (TCP/IP) and Network File System (NFS) software, you can configure your system to communicate over a network.

After you install TCP/IP and NFS software, use the Web-based System Manager, wsm, or the System Management Interface Tool (SMIT) fast path, smit tcpip, to configure your system. The online help guides you through the process.


The TCP/IP software must be installed. If you install TCP/IP software, you will have to install the TCP/IP Optional Support software product.

You must have root authority to configure TCP/IP.

Updating the Hosts List

A name server is a machine on your network that stores the names and addresses of all the network machines. The names are stored in a Hosts List. When one machine wants to communicate with another, it sends that machine name to the name server. The name server refers to the Hosts List and responds with the address of the machine name requested. Having a name server is an advantage because the Hosts List is stored and updated at one location, but is accessible to all machines on the network. This saves time and storage space.
