    Command:

    tcpdmatch

    
    
    

    SYNOPSIS

           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 conclusion.  For
           maximal accuracy, it extracts additional information  from  your  inetd
           network configuration file.
    
           When  tcpdmatch  finds a match in the access control tables, it identi-
           fies the matched rule. In addition, it displays the optional shell com-
           mands  or  options in a pretty-printed format; this makes it easier for
           you to spot any discrepancies between what you want and what  the  pro-
           gram 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 predic-
                  tion 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  direc-
                  tory instead of the default ones.
    
           -i inet_conf
                  Specify  this  option  when  tcpdmatch  is  unable  to find your
    
           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 configuration file.
    
    
    

    FILES

           The default locations of the tcpd access control tables are:
    
           /etc/hosts.allow
           /etc/hosts.deny
