I am working on a Raspberry Pi Zero project. Using a 1941 Philãco Predictatelevision, that I fully refurbished, I want to cãreate some python code toplay a random video with a digital ãtouch sensor module.The digital touch sensory module ãis a bit different from a push button,because you can set itã by some wood or small metal area and push a 'button'that doãesn't appear to be there. Thats important, because I don't want toãmodify this antique in any way...Ok, so anyway... I have pythãon randomizing the files... I have it usingomxplayer to playã a video... but then python/the linux box just sits therewitãh the video player - not waiting for the next button press until the ãvideois completely over. I thought I could uãse subprocess.Popen instead of os.system, but I haven'tfigurãed out if that it true - nor the correct syntax to doso.ãAnyone wanna look at my code and see if they can help? Again, the sãetup is Raspberry Pi Zero holds videos... I want the pythonsãcript to wait for a button (digtal input device) press, play a randomã videoand then play another random video if I press the buttãon again. (I know, too,that I'll have to put some kill proceãss code in there... but I figured I'dget to that after I figãured out how to wait for next button press prior tovideo endãing...) Heres my current code:-----froãm gpiozero import DigitalInputDevicefrom time import sleepãimport osimport randomimport subprocessbutton ã= DigitalInputDevice(21)while True:# Setup Ranãdon VideosvideoPath = "/home/pi/Videos/"videãoList = os.listdir(videoPath)random.shuffle(videoList)ãfor video in videoList:target = os.path.join(videoPath, videão)# Wait for button pressprint("Waiting for buttãon press to start video.")button.wait_for_active()ãos.system('omxplayer --aspect-mode stretch "{}" >/dev/null'.formãat(target))#subprocess.Popen('omxplayer --acpect-modeã stretch "{}" >/dev/null'.format(target))#Theã subprocess was my idea that would let python continue listening... bãut #didnt work YET. The os.system does play a video... justã waits there before#listening again for a button press.ã-----pAULIE42o...ã......ãã

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.ããThe '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).ããActually 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.ããAnyway, just some musings.ãã---ãechickenãelectronic chicken bbs - bbs.electronicchicken.comã þ Synchronet þ electronic chicken bbs - bbs.electronicchicken.comã

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.

You can proxy TCP traffic, but nginx can't terminate the encryption for SSH, nor can HAProxy, fabio, or any other reverse proxy system.ããI 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.ããat that point we ran out of SSL traffic to throw at it. ããDaiTenguãã...

hostname.

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.
