Configuration of TCP/IP

Edit online

After the TCP/IP software is installed on your system, you are ready to begin configuring your system.

Many TCP/IP configuration tasks can be performed in more than one way, either by:

  • Using the System Management Interface Tool (SMIT)
  • Editing a file format
  • Issuing a command at the shell prompt.

For example, the rc.net shell script performs required minimum host configuration for TCP/IP during the system startup process (the rc.net script is run by the configuration manager program during the second boot phase). By using SMIT to perform the host configuration, the rc.net file is configured automatically.

Alternatively, you can configure the /etc/rc.bsdnet file using a standard text editor. With this method, you can specify the traditional UNIX TCP/IP configuration commands such as ifconfig, hostname, and route. If using the file edit method, you must enter smit configtcp fast path and then select BSD Style rc Configuration. See List of TCP/IP Programming References in Communications Programming Concepts for information about TCP/IP files and file formats.

A few tasks, such as configuring a name server, cannot be done using SMIT.
