TCPDMATCH (8) | System administration commands and daemons | Unix Manual Pages

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 conclusion. For maximal accuracy, it extracts additional information 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 format; 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.
