    NAME
         tcpdmatch - tcp wrapper oracle
    
    SYNOPSYS
         tcpdmatch [-d] [-i inet_conf] daemon client
    
         tcpdmatch [-d] [-i inet_conf] daemon[@server] [user@]client
    
    DESCRIPTION
         tcpdmatch predicts  how  the  tcp  wrapper  would  handle  a
         specific request for service.  Examples are given below.
    
         The program examines the tcpd access control tables (default
         /etc/hosts.allow and /etc/hosts.deny) and prints its conclu-
         sion.  For maximal accuracy, it extracts additional informa-
         tion from your inetd or tlid network configuration file.
    
         When tcpdmatch finds a match in the access  control  tables,
         it identifies the matched rule. In addition, it displays the
         optional shell commands or options in a pretty-printed  for-
         mat;  this makes it easier for you to spot any discrepancies
         between what you want and what the program understands.
    
    ARGUMENTS
         The following two arguments are always required:
    
         daemon
              A daemon process name. Typically, the last component of
              a daemon executable pathname.
    
         client
              A host name or network address, or one of the `unknown'
              or `paranoid' wildcard patterns.
    
              When a client host name is specified, tcpdmatch gives a
              prediction for each address listed for that client.
    
              When a client address is specified, tcpdmatch  predicts
              what tcpd would do when client name lookup fails.
    
         Optional information specified with the daemon@server form:
    
         server
              A host name or network address, or one of the `unknown'
              or  `paranoid'  wildcard  patterns.  The default server
              name is `unknown'.
    
         Optional information specified with the user@client form:
    
         user A client user identifier. Typically, a login name or  a
              numeric userid.  The default user name is `unknown'.
    
    OPTIONS
         -d   Examine hosts.allow and hosts.deny files in the current
              directory instead of the default ones.
    
         -i inet_conf
              Specify this option when tcpdmatch is  unable  to  find
              your  inetd.conf  or  tlid.conf  network  configuration
              file, or when you suspect that  the  program  uses  the
              wrong one.
    
    EXAMPLES
         To predict how tcpd would handle a telnet request  from  the
         local system:
    
              tcpdmatch in.telnetd localhost
    
         The same request, pretending that hostname lookup failed:
    
              tcpdmatch in.telnetd 127.0.0.1
    
         To predict what tcpd would do when the client name does  not
         match the client address:
    
              tcpdmatch in.telnetd paranoid
    
         On some systems, daemon  names  have  no  `in.'  prefix,  or
         tcpdmatch  may need some help to locate the inetd configura-
         tion file.
    
    FILES
         The default locations of the tcpd access control tables are:
    
         /etc/hosts.allow
         /etc/hosts.deny
