    The real 'programmer tool' is nc(1)

    A telnet substitute using this:

    telnet has been deprecated all over the place because it is horribly insecure. There are mush better ways to connect to a remote machine,
    starting with ssh.

    That too, though finding anyone who willingly has a relent port open is
    very rare anymore.


    Straight from nc's manpage:

    'The nc (or netcat) utility is used for just about anything under the
    sun involving TCP or UDP. It can open TCP connections, send UDP
    packets, listen on arbitrary TCP and UDP ports, do port scanning, and
    deal with both IPv4 and IPv6. Unlike telnet(1), nc scripts nicely, and separates error messages onto standard error instead of sending them to standard output, as telnet(1) does with some.'

    If one has been touch typing

    telnet host.slt.TLD 22
    telnet host.slt.TLD 25
    telnet host.slt.TLD 587
    telnet host.slt.TLD 80

    for several decades, even

    nc host.slt.TLD 22

    does not come easy, let alone

    openssl s_client -connect host.slt.TLD :22

    The deprecation is satisfied by blocking port 23 (at least incoming)
    on the firewall.
