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 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'.

Maintenance Commands                               TCPDMATCH(1M)

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 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
