NAME

if.ignore − data base of ignored network interfaces

DESCRIPTION

The if.ignore file allows a system administrator to specify network interfaces that should be ignored by certain network applications.  Use of this file is determined by the individual application.  This file is referenced by the ifignore library function. 

Each line of the file has the following format:

interface [ server ] [ server ] . . . 

Items are separated by any number of blanks and/or tab characters.  server names should be the device or service alias as it appears in the /etc/services file.  The server names are optional and specify network services which should ignore the given interface.  If no server names are supplied on a particular line, the corresponding interface should be ignored by all network services (which consult this file). 

EXAMPLES

The following example illustrates how the if.ignore file might be used:

sl0     who   timed
sl1     router
ppp0

No rwhod or timed packets should be broadcast over the sl0 or ppp0 interfaces.  Likewise, no routed packets should be broadcast over the sl1 or ppp0 interfaces.  Furthermore, the ifignore() library function will return a non-zero value for all services requiring the ppp0 interface and it will return zero for any interfaces other than ppp0, sl0, or sl1.
