NAME

Net::Netcat - A wrapper class for nc Swiss army knife of networking

DESCRIPTION

A simple interface for using netcat command line utility. You can run TCP, UDP or UNIX domain servers and clients.

SYNOPSIS

use Net::Netcat;

my $nc = Net::Netcat->new('/usr/bin/nc');

my $result = $nc->exec(); croak $nc->errstr unless $result;

$nc->exec();

$nc->options{ '-s' => 'source IP', '-p' => 'source port', };

$nc->exec()

        # All options in OpenBSD netcat
        ipv4only            => '-4',
        ipv6only            => '-6',
        staylistening       => '-k',
        listenmode          => '-l',
        nodns               => '-n',
        randomports         => '-r',
        md5sign             => '-S',
        rfc854telnet        => '-y',
        unixsocket          => '-U',
        udpsocket           => '-u',
        verbose             => '-v',
        scanmode            => '-z',
        tcprecvbuff         => '-I length',
        tcpsendbuff         => '-O length',
        delaypkt            => '-i interval',
        sourceport          => '-p source_port',
        sourceip            => '-s source',
        toskeyword          => '-T tos',
        timeout             => '-w timeout',
        port                => '-port port',
        dest                => '-dest destination_to_connect_to'

        $nc->options{'-v' => 1,'-4' => 1, '-l' => 1, 'port' => 2300};
        $nc->exec();

METHODS

new('/usr/bin/nc')

        Contructs Net::Netcat object.It takes a path of netcat command.
        You can omit this argument and this module searches netcat command within PATH environment variable.

        I tested and developed this on OpenBSD 5.2 netcat. This is
substantially different from Linux netcat. So kindly sene me bug
reports.

        There seems to be a bug in netcat with UNIX domain sockets and
the verbose flag. So don't use that combo. Usually you have to
terminate the command with the Ctrl-C keyboard interrupt signal. You
could also redirect the output to a file if desired.

options( @options )

        Specify netcat command options directly

execute()

        Executes netcat command with specified options.

exec()

An alias of execute()

stdout()

        Get netcat command output to stdout.

stderr()

        Get netcat command output to stderr.

        Specify output file name and output options.

        Avaiable options are:

destination

        The destination IP address to connect to or in case of UNIX
domain sockets the destination socket file to connect to

port

        The port to connect to
