OIDENTD_MASQ.CONF(5) oidentd User Manual OIDENTD_MASQ.CONF(5)
NAME
oidentd_masq.conf - oidentd NAT configuration file
DESCRIPTION
If NAT support is enabled with the --masquerade option, oidentd reads
the /usr/local/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".
