8.31: Can I use perl to run a telnet or ftp session?

    Try the Net::FTP, TCP::Client, and Net::Telnet modules (available from
    CPAN). http://www.cpan.org/scripts/netstuff/telnet.emul.shar will also
    help for emulating the telnet protocol, but Net::Telnet is quite
    probably easier to use..

    If all you want to do is pretend to be telnet but don't need the initial
    telnet handshaking, then the standard dual-process approach will

        use IO::Socket;             # new in 5.004
        $handle = IO::Socket::INET->new('www.perl.com:80')
                || die "can't connect to port 80 on www.perl.com: $!";
        if (fork()) {               # XXX: undef means failure
            print while <STDIN>;    # everything from stdin to socket
        } else {
            print while <$handle>;  # everything from socket to stdout
        close $handle;
