my Dns is resolving ip address, I carried out your suggestion to test the dns and the Dns work fine.
when I disabled tcp wrappers in /etc/inetd.conf
I was able to ftp from anywhere and no warning message in syslog
but with tcp wrappers enable in /etc/inetd.conf
that is
ftp stream tcp6 nowait root /usr/local/bin/tcpd /usr/sbin/in.ftpd -l
then ftp from my LAN does not work hence error message in syslog

REDIR(1) General Commands Manual REDIR(1)
NAME
redir - redirect tcp connections
SYNOPSIS
redir [--laddr=incoming.ip.address] [--caddr=host] [--debug] [--syslog] [--name=str] [--timeout=n] [--bind_addr=my.other.ip.address] [--ftp=type]
[--transproxy] [--connect=host:port] --lport=port --cport=port [--bufsize=n] [--max_bandwidth=n] [--random_wait=n] [--wait_in_out=n]
redir --inetd [--caddr=host] [--debug] [--syslog] [--name=str] [--timeout=n] [--ftp=type] [--transproxy] [--connect=host:port] --cport=port
[--bufsize=n] [--max_bandwidth=n] [--random_wait=n] [--wait_in_out=n]
DESCRIPTION
Redir redirects tcp connections coming in to a local port to a specified address/port combination.
It may be run either from inetd or as a standalone daemon. Depending on how redir was compiled, not all options may be available.
OPTIONS
--lport
Specifies port to listen for connections on (when not running from inetd)
--laddr
IP address to bind to when listening for connections (when not running from inetd)
--cport
Specifies port to connect to.
--caddr
Specifies remote host to connect to. (localhost if omitted)
--inetd
Run as a process started from inetd, with the connection passed as stdin and stdout on startup.
--debug
Write debug output to stderr or syslog.
--name Specify program name to be used for TCP wrapper checks and syslog logging.
--timeout
Timeout and close the connection after n seconds of inactivity.
--syslog
Log information to syslog.
--bind_addr
Forces redir to pick a specific address/interface to bind to when it listens for incoming connections.
--ftp When using redir for an FTP server, this will cause redir to also redirect ftp connections. Type should be specified as
either "port", "pasv", or "both", to specify what type of FTP connection to handle. Note that --transproxy often makes one
or the other (generally port) undesirable.
--transproxy
On a linux system with transparent proxying enabled, causes redir to make connections appear as if they had come from their
true origin. (see /usr/share/doc/redir/transproxy.txt)
--connect
Redirects connections through an HTTP proxy which supports the CONNECT command. Specify the address and port of the proxy
using --caddr and --cport. --connect requires the hostname and port which the HTTP proxy will be asked to connect to.
--bufsize n
Set the bufsize (defaut 4096) in bytes. Can be used combined with --max_bandwidth or --random_wait to simulate a slow con-
nection.
--max_bandwidth n
Reduce the bandwidth to be no more than n bits/sec. The algorithme is basic, the goal is to simulate a slow connection, so
there is no pic acceptance.
--random_wait n
Wait between 0 and 2 x n milliseconds before each "packet". A "packet" is a bloc of data read in one time by redir. A
"packet" size is always less than the bufsize (see also --bufsize).
--wait_in_out n
Apply --max_bandwidth and --random_wait for input if n=1, output if n=2 and both if n=3.
