Help is needed #3

Closed darkobg79 closed 9 months ago

darkobg79 commented 11 months ago

Greeting. The project is fantastic, congratulations.

I need help. I have an idea that I want to implement, but I can't.

In short, I want to run a service on one server (OS) that will create a VPN to Dahua servers and enable RTSP.

From the second computer, I want to access the IP address of the first computer and watch the stream created in this way.

I manage connect and the system creates a VPN. However, I can't watch the stream at all.

khoanguyen-3fc commented 11 months ago

It's great that you've explored the enhanced Rust implementation, and it seems our scenarios align.

Regarding the issue you're facing, please note that the tunnel is still in the process of establishing until you see the "Ready to connect!" message in the log.

Have you tried aborting and retrying the process multiple times? I've noticed my PoC still occasionally hangs in the middle of establishing, so this might be worth exploring.

darkobg79 commented 11 months ago

I never seen message "Ready to connect"... I will try again.

darkobg79 commented 11 months ago

As far as I can see, the last step does not pass: P2P handshake

darkobg79 commented 11 months ago

Can you try: 4L0A4AAPBQCAC1B ?

khoanguyen-3fc commented 11 months ago

I've checked and found that, for some reason, a direct connection to your device isn't possible. Instead, it has to use relay mode, which is not yet supported.

darkobg79 commented 11 months ago

Is there a plan to implement and support relay mode in next period? :)

khoanguyen-3fc commented 11 months ago

I've drafted an experimental relay mode in the feature/relay branch. You might want to give it a try.

Keep in mind that it's currently an experimental feature as part of a proof of concept, so more effort and help are needed to finalize it.

darkobg79 commented 11 months ago

It not working... I don't see Ready to connect...

khoanguyen-3fc commented 11 months ago

Did you specify -r / --relay option?

darkobg79 commented 11 months ago

You are a genius 🥇 👍

p2p-sys commented 11 months ago

Can you repeat this in a Python3 program?

khoanguyen-3fc commented 11 months ago

@darkobg79 I haven't successfully tested it yet. I'm only able to see half of the first frame, possibly because Easy4IPCloud Agent detects that my device can connect directly and stops relaying.

@p2p-sys I gave it a quick try, but unfortunately, it failed. The polling and non-async architecture of my Python script make it less flexible. Moving forward, I'll be focusing exclusively on Rust development, keeping the Python one only as a reference.

darkobg79 commented 11 months ago

@khoanguyen-3fc How can I send you the account to test? I can't create a temporary account, this is a shared account that we use.

khoanguyen-3fc commented 11 months ago

@darkobg79 For now, I won't need a testing account if you can confirm that this feature is working.

Can you provide more details on its reliability? Does it work consistently, run smoothly, and how long can you watch without issues? These issues may be related to the overall protocol finalizing that I'm working on, not specific to relay.

darkobg79 commented 10 months ago

@khoanguyen-3fc After the new changes, everything is much more stable. Before the changes, everything worked for up to one minute. Now I tested it only once, it works for about 5-6 minutes and then stops.
