/usr/bin/tcpdmatch [-d] [-i inet_conf] daemon@[server]
[user@]client
The second syntax can be used when your server has more than one
address or name.
Where
“daemon” is a daemon process name.
“client” is a host name or network address, or one of the ‘unknown’ or
‘paranoid’ wildcard patterns.
Optional information specified with the “daemon@server” and
“user@client” forms:
“server” is a host name or network address, or one of the ‘unknown’
or ‘paranoid’ wildcard patterns. The default server name is
‘unknown’.
“user” is a client user identifier. Typically, it is a login name or a
numeric user id. The default user name is ‘unknown’.
The following example illustrates how tcpd would handle a ftp
request from a local system:
tcpdmatch ftpd localhost
Pretending that the hostname lookup fails, the same request would
be handled by tcpd as follows:
tcpdmatch ftpd 127.0.0.1
To predict what tcpd would do when the client name does not match
the client address:
tcpdmatch ftpd paranoid
NOTE Refer to tcpdmatch(1) man page for more information.
Refer to hosts_access(5) man page for more information on wildcard
patterns.
