• Python help...

    From paulie420@VERT/BEERS20 to All on Tuesday, September 01, 2020 16:43:00
    I am working on a Raspberry Pi Zero project. Using a 1941 Phil
    co Predictatelevision, that I fully refurbished, I want to c
    reate some python code toplay a random video with a digital
    touch sensor module.The digital touch sensory module
    is a bit different from a push button,because you can set it
    by some wood or small metal area and push a 'button'that do
    esn't appear to be there. Thats important, because I don't want to
    modify this antique in any way...Ok, so anyway... I have pyth
    on randomizing the files... I have it usingomxplayer to play
    a video... but then python/the linux box just sits therewit
    h the video player - not waiting for the next button press until the
    videois completely over. I thought I could u
    se subprocess.Popen instead of os.system, but I haven'tfigur
    ed out if that it true - nor the correct syntax to doso.
    Anyone wanna look at my code and see if they can help? Again, the s
    etup is Raspberry Pi Zero holds videos... I want the pythons
    cript to wait for a button (digtal input device) press, play a random
    videoand then play another random video if I press the butt
    on again. (I know, too,that I'll have to put some kill proce
    ss code in there... but I figured I'dget to that after I fig
    ured out how to wait for next button press prior tovideo end
    ing...) Heres my current code:-----fro
    m gpiozero import DigitalInputDevicefrom time import sleep
    import osimport randomimport subprocessbutton
    = DigitalInputDevice(21)while True:# Setup Ran
    don VideosvideoPath = "/home/pi/Videos/"vide
    oList = os.listdir(videoPath)random.shuffle(videoList)
    for video in videoList:target = os.path.join(videoPath, vide
    o)# Wait for button pressprint("Waiting for butt
    on press to start video.")button.wait_for_active()
    os.system('omxplayer --aspect-mode stretch "{}" >/dev/null'.form at(target))#subprocess.Popen('omxplayer --acpect-mode
    stretch "{}" >/dev/null'.format(target))#The
    subprocess was my idea that would let python continue listening... b
    ut #didnt work YET. The os.system does play a video... just
    waits there before#listening again for a button press.

    Not sure what editor you're using... but all the ANSi code intermingled
    makes it nearly impossible to actually read through on a non-terminal.

    I do run both; American Pi is @ AmericanPiBBS.com and 20 For Beers is @ 20ForBeers.com:1337 ...

    Guess I should have stated such; point was that I must have the QWK settings messed up for the Mystic BBS cause Digital Man says I was missing a QWK tag line or kludge line... and another poster said my messages had tons of extra character garbage.

    So I have been trying not to post much - and need to go iron that out so my Mystic BBS posted posts come thru normal. :/

    I've been doing a lot of work with NGINX and reverse proxying
    HTTP/HTTPS. If there were a way to reverse proxy SSH, I'd love it -
    throw a ton of different BBSes behind a proxy and sort them out by
    hostname.

    Nothing so easy as inspecting a Host header and making it all totally seamless for the user, as far as I know.

    I'm vaguely imagining a custom SSH server which is used for encryption but not authentication. The user connects with eg. 'target_bbs@multi.bbs.host', no password required. The server knows what 'target_bbs' is and proxies between it and the client. From there, as far as the user is concerned, their BBS session flows as it would've done had they telnetted in.

    The 'server' in the above scenario could be a small piece of custom software (which I think would be easy to write). Or Synchronet could do that job in a slightly hacky way (some special user accounts, a hack of the logon script, and telgate).

    Actually authenticating the user via SSH and then handing them off to the target BBS without requiring additional login would depend on capabilities of the target software. I suspect this would be inconsistent and annoying.

    Anyway, just some musings.

    You can probably do that with stock software already.

    Create a user account in your proxy machine for every BBS you want to reverse proxy for. Then configure such user to be capable of connecting to each target BBS only. This way if the client does synchronetclone@proxymachine.org, user "synchronetclone" is called up and inmediatelly connects to the "SinchronetClone" BBS.

    It is not exactly transparent, I know.

    I have looked into OpenBSD's relayd but it does not look like it has that function.

    Unfortunately that's not possible. You can proxy TCP traffic, but nginx can't terminate the encryption for SSH, nor can HAProxy, fabio, or any other reverse proxy system.

    I just set up a reverse NGINX proxy on a dual-64 core EPYC (7742) server this week. We had it handling about 70,000 SSL connections per second (real world traffic) while only running around 45% CPU usage, with SMT (AMD's version of hyperthreading) turned off.

    at that point we ran out of SSL traffic to throw at it.

    Probably could with client keys and credential forwarding... you can
    also do a reverse proxy over a websocket, but that would something on
    the client to handle that aspect.

    Would love it if syncterm supported wss+PROT and/or ws+PROT so you could
    do rlogin/telnet/ssh over a websocket connection. Of course that messes
    with the IP detected on the backing server/service.

    If all it does is reverse-proxy, may also want to take a look at Caddy
    v2, and see if you get more throughput.

    We use some nginx modules as well. I'd have to dig through Caddy and see if there's anything similar.

    I'm more worried about the Linux kernel limitations than anything else.

    I guess we'll see how it goes! :)
