NAME

       oidentd_masq.conf - oidentd NAT configuration file

DESCRIPTION

       If NAT support is enabled with the --masquerade option, oidentd reads the /etc/oidentd_masq.conf file to
       determine Ident responses to queries intended for other machines. It is also possible to forward queries
       to Ident servers on the hosts connecting through the machine oidentd runs on. For more information on
       forwarding, please see the --forward option in oidentd(8).

       The NAT configuration file contains one rule per line. Lines are read from top to bottom, and only the
       first matching rule is used. Lines starting with a number sign ("#") are ignored.

RULE FORMAT

       Rules must have the following form:

           host[/mask] response system-type

       The host field specifies the hostname or IP address of the host that owns the connection for which an
       Ident query was received. This host must be connecting through the machine oidentd runs on. The host may
       be specified as either an IP address or a hostname.

       If a network mask is specified using the mask field, the rule applies to all hosts in the given
       subnetwork. Network masks may be specified in dot notation (e.g., "255.255.192.0") or in CIDR notation
       (e.g., "18").

       The response field specifies the response to be sent when receiving a query for the specified host or
       subnetwork.

       The system-type field specifies the operating system to send alongside the Ident response. See the
       --other option in oidentd(8) for more information.

EXAMPLES

           # host[/mask]           response  system-type
           10.0.0.1                user1     UNIX
           server.internal         user2     UNIX-BSD
           10.0.0.0/24             user3     UNIX
           10.0.0.0/255.255.0.0    user4     UNKNOWN

       Note that the order of the rules is significant in this example. Due to lines being read from top to
       bottom, more specific rules must precede more general ones. For example, the rule for "10.0.0.1" would
       not match any connections if it were preceded by the more general "10.0.0.0/24".
