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'm still running Sync!! But have a mystic... however, I guess I need to fix
my QWK so I'm trying not to make a bunch of posts... my messages dont have a QWK tagline.

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 onlñy. 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! :)
