The settings from host.conf may be overridden using a number
|
|
of environment variables. These are
|
|
<dl>
|
|
<dt> RESOLV HOST CONF <dd>This specifies a file to be read instead of
|
|
/etc/host.conf.
|

|
|
|
|
<dt> RESOLV SERV ORDER <dd>Overrides the order option given in host.conf. Services are given as hosts, bind, and nis, separated by a space,
|
|
comma, colon, or semicolon.
|
|
|
|
|
|
<dt> RESOLV SPOOF CHECK <dd>Determines the measures taken against spoofing. It is
|
|
completely disabled by off. The values warn and warn off
|
|

|
|
logging facility as defined in host.conf.
|

|
|
