[Solved] Websockets ports

[gofterdom]

No I want to learn ! But I thought you wanted me to rewrite my project in Python and felt overwhelmed lol
I'm on it now !

[gofterdom]

By the way this will feel like the smallest step for you, but the html/js part of the website actually works now on heliohost ! even if the server doesn't 

[gofterdom]

Ok so :

 

I've followed all the steps to start and stop the bot, but i've replaced the .py bot by server.js (my server script, placed in root directory). I've added the same permissions. Is that what was expected ?

Unfortunately  citadel.helioho.st/bot_control/ only shows : 

Cannot GET /bot_control/

i've also tried the full adress :
console error : bot_control/:1 
            
            
           GET https://citadel.helioho.st/httpdocs/bot_control/ 404 (Not Found)

The tutorial said to check the bot logs but i cannot find them in the bot_control dir. There are logs in the log dir, but i don't know which ones are the bot one.

Am I on a wrong track ?

Ok i managed to find it by going directyly to https://citadel.helioho.st/bot_control/index.sh

but now it's giving me errors, that seems like it's expecting a python document and not a js document, the comments are not read as comment...

I THINK i managed to adapt the bash script to start the node.js server.js script using passenger, but it feels like there is not much i can do now, since ports are not open to me...

I don't know how to stop the node using passenger though. Can you please help me with the next steps ?

Passenger automatically kills your Node.js server after 5-10 minutes without any page hits. That's why I was recommending starting and stopping your websocket with the /bot_control/index.sh script if you want it to run for more than 5 minutes.

[gofterdom]

I have not been able to start and stop the websocket from the /bot_control/index.sh script, it is looking for the node install folder and i don't know where to indicate it.

it is looking in /usr/local/bin/node, but not finding it

Could you please tell me what i need to change in that bash script to make it work with node.js ?

In its initial state, it seemed to be looking for a python file only

apologies for taking your time, i have been trying all day

Instead of this

Try this

if [ "$QUERY_STRING" == "action=start" ]; then
    if [ $running -ne 0 ]; then
        echo "$bot_name is already running..."
    else
        echo "[$ts] Starting $bot_name." >> $pwd/$log_name
        /opt/plesk/node/22/bin/node /home/$main_domain/$bot_name >> $pwd/$log_name 2>&1 &
        echo "Starting $bot_name...<script>window.location.replace('/$control/');</script>"

thank you, it seems to work !

 

now i'm blocked by the port issue we discussed, but i'm guessing that's expected ? Only need the apache/nginx redirect that was mentioned in the FAQ ? Or am i forgetting something

Switch to another port other than 3000. Obviously someone else is using 3000.

[gofterdom]

I thought the whole point was that no port was available ;( that's why i didn't try further

I switched to 8080 and it works now indeed :

server.js is running. Stop
Current memory usage: 62.12 MB
Estimated 24 hour usage: 87.36 GB - Check Load

However on the main game itself :
 

network.js:3 WebSocket connection to 'wss://citadel.helioho.st/' failed:

	setupWebSocket	@	network.js:3
	(anonymous)	@	game.js:39

 

Is that where nginx/apache are needed ?

I've been able to stop the script as well

No external ports are available, and we don't open them in the firewall on Morty, Tommy, or Johnny. Internal ports are basically all available, but they can't be accessed remotely without proxying them through Apache or Nginx because the firewall blocks the direct connection. There are 65535 internal ports, and only a handful are in use by other users.

Right now Passenger is blocking access to everything on your domain, so we need to either add another subdomain to access /bot_control/ or you'll need to disable Passenger.

[gofterdom]

I am unsure if there is something else I can do from my side ? You said :

we need to either add another subdomain to access /bot_control/ or you'll need to disable Passenger.

I am down for either, but as I mentioned, I am lost. Is there a tutorial I can follow for any one of these options ? 

I'll be glad to stop bothering you, I just don't know what i'm supposed to do next

 

 

[Krydos]

Ok, let's leave Passenger on for your main domain so you can play around with that. I created 2 subdomains for you: wss.citadel.helioho.st which we'll use for your websocket, and control.citadel.helioho.st that we'll use for your start/stop/logs index.sh script. The new domains should start working in about 100 minutes or so. You can go ahead and move the .htaccess file and index.sh file from /home/citadel.helioho.st/httpdocs/bot_control/ to /home/citadel.helioho.st/control.citadel.helioho.st/ We'll work on this more when the domains are ready.

[gofterdom]

Thanks a lot ! I have moved the files. I am going to bed now but will carry on first thing tomorrow
