  • Stopping DUMB terminal access

    From Pilotcab@1:103/705 to All on Tue Sep 13 20:07:58 2022
    Hi all

    I know this is probably going to cause a few stains on the underwear of some people, but is it possible to
    just drop any connections that com ein as "dumb terminals" ??

    or maybe even those that don't receive telnet commands...

    BEFORE ANYONE ASKS....... yes i blocked the usual suspects... chicoms, ruscoms, et al but im still getting a few hits from over her ein the states etc.


    Any help appreciated

    Set [login] inactivity_hangup=1 in your ctrl/modopts.ini and dumb terminals will be disconnected in one second of inactivity.

    Or you could add a couple lines to your exec/login.js file:
    if(client.protocol == "Raw")
    bbs.hangup();

    inactivity.

    This has helped a lot.

    bbs.hangup();

    not sure where to put this :D i put it right after where it checks for ansi/petscii etc and would d/c right away, so right now i've put it in the block where it cuts the timeout. which seems to work.

    Would it hurt to have both??

    i started with the first one and it effectively killed all the logins..

    now i have the second one after the bit where it changes the inactivity timeout:

    <line 29> log(LOG_NOTICE, "terminal not detected, reducing inactivity hang-up timeout to " + console.inactivity_hangup + " seconds");

    that way it changes it then dumps them... but i also finally added some GEO-IP blocks so it blocks most of them straight off, then the ones from the US get hung up on.

    I wouldn't make either change myself. I'm happy to serve legacy/retro clients that may not do ANSI or Telnet (e.g. C64 clients).

    Figured I'd chime in here.

    I've had a few users that love their "retro" gear (amigas, commodores, custom "8088" emulators, etc.), and some of them wind up connecting as "RAW". So you could possibly dump legitimate users by hanging up on any dumb terminals.

    OK, I can remove them...right now, I am limiting max concurrent
    connections to 1, but if they don't get past Lord Blackfair's
    CAPTCHA, they won't get in.

    that is a good point and one i never thought of (not that anyone but me "calls" my bbs anyway :D).

    OK, I can remove them...right now, I am limiting max concurrent connections to 1, but if they don't get past Lord Blackfair's
    CAPTCHA, they won't get in.

    I went back to another way of doing it and just geoblocking the countries in iptables.

    I still get a couple through from the US, but the persistant ones i just manually block :D
