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

Current Perl documentation can be found at

Here is our local, out-dated (pre-5.6) version:

Try the Net::FTP, TCP::Client, and Net::Telnet modules (available from CPAN). 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 suffice:

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