       oidentd_masq.conf - oidentd IP masquerading/NAT configuration file.


       If  you are using IP masquerading or NAT, oidentd can optionally return
       a username for connections from other machines.  Support  for  this  is
       specified  by  calling  oidentd  with  the  -m  (or --masq) flag and by
       creating an /etc/oidentd_masq.conf file.

       oidentd can also forward requests for an IP masqueraded  connection  to
       the  machine  from which connection originates by way of the -f option.
       This will only work if the host to which the connection is forwarded is
       running oidentd with the -P (proxy) flag, or if the host’s ident daemon
       will return a valid reply regardless of the input supplied by  and  the
       address of the host requesting the info (some ident daemons for windows
       do this, maybe others).


       <IP Address|Hostname>[/<Mask>] <Ident Response> <System Type>

       The first field contains the IP address or the hostname  of  a  machine
       that  IP  masquerades  through  the machine on which oidentd runs.  The
       mask parameter can be either a network mask or a mask in CIDR notation.
       A mask of 24 is equivalent to, a mask of 16 is equivalent
       to, etc.

       The second field specifies the  reply  that  oidentd  will  return  for
       lookups  to  the  host  matching  the IP address specified in the first

       The third field specifies the operating system the machine matching the
       first parameter is running.
