NAME

iftab − network interface configuration file

SYNOPSIS

/etc/ftab

DESCRIPTION

/etc/rc.net reads /etc/iftab to determine what configuration commands are to be applied to the machine’s network interfaces.  Each line in /etc/iftab is a rule beginning with an interface pattern followed by a protocol/address family and a set of parameters passed to /etc/ifconfig or  the command line to execute.  Each interface present on the machine will be matched against the interface patterns in this file and the first one found for each unique protocol/address familiy will be executed. 

The interface name can use asterisks (∗) to match any substring.  The protocol/address family can be any string.  The rest of the line will be passed to /etc/ifconfig unless it is preceeded by an exclamation point (!). An excalmation point indicates that the rest of line will be executed as a command, and the variable $if refers to the interface name to be configured. 

An interface name of “-1-” will match the primary interface. 

An argument string of “-HOSTCONFIG-” will redirect /etc/rc.net to get the network configuration from the /etc/hostconfig file. 

To disable an interface, enter a line with the name of the interface and an action of “!false” (or any command that is a no-op).
