Whats the difference between WebRTC and libp2p?

Asked 2022-Mar-16 at 19:49

I'm trying to build a p2p terminal sharing utility where PCs behind a NAT can share their terminals to other PCs behind a NAT through the public internet. (both PCs are on different private network basically). Another requirement is to provide a web based terminal as well ( and hence webrtc seems useful ) .Came across two promising solutions - webrtc and libp2p. But what is the fundamental difference between the two?

PS: ssh Tag might be misleading here. But on a broad level, all I'm trying to do is a make-believe SSH into a system that does not have a public IP

WebRTC is a low-level Browser API for P2P communication between browsers. See MDN documentation or Wikipedia article for high-level introduction and history.
libp2p is a library written in JS, NodeJS, Go, Rust (with more in the way) that implements Peer to Peer communication based on IPFS. From what I see it uses WebRTC and WebSockets in Browser.

I solved this by blowing away everything in my /vendor dir, and .gitignoring it. This forced GitHub actions to redownload everything. Not sure if this was the most efficient solution, but worked for me!

You're working with YAML so take care about the indentation since it's really important.

Since you're declaring initContainers, on the first level you define Containers; but you included the following on that level:

Unfunny story - my example presented in the question is correct - but there is a bug in rust-libp2p which breaks the interoperability with go-libp2p. See https://github.com/libp2p/rust-libp2p/pull/2309 for details

libp2p node gives Error: connect ECONNREFUSED

From outside the docker I can connect to the node by using p2p addr: /ip4/127.0.0.1/tcp/3333/p2p/Q… so I know the libp2p node is up and listening and docker-proxy is connecting to the container on that port.

ANSWER

Answered 2021-Aug-19 at 08:06

When creating the libp2p node the ip address must be 0.0.0.0 instead of 127.0.0.0 or the real server's ip.

Then, when trying to remotely reach the libp2p node, the ip has to be that of the server (the one that ping your-domain.com returns)

Imo 80% of development pain comes from too simple examples in the "documentation"

Substrate 3.0 "on_runtime_upgrade" function does not work

I want to try "Runtime Upgrade" and "Storage Migration". I tried by steps as following,but "on_runtime_upgrade" function did not work. Unable to verify that the "on_runtime_upgrade" function is called. The implemented debug log is not output.

Download "substrate-node-template 3.0".
Compile it.
I ran the node with the following command. "target/release/node-template --dev -l runtime = debug".
Implement "on_runtime_upgrade" in "palet-template".The program I tried "substrate-node-template/pallets/template/lib.rs" is listed below.
Compile it by "cargo build --release -p node-template-runtime" command.
Upload "node_template_runtime.compact.wasm" by using "sudo" & "setcode" command.
I checked the execution log of the node, but I couldn't check the log set to "on_runtime_upgrade".
