Notes: Great Firewall of China

[dukejones]

So, my artist friend is in China, and he wants to share another WebGL-rendered 3D world over IPFS.

ipfs daemon
ERRO[00:01:02:000] mdns lookup error: failed to bind to any unicast udp port  module=mdns

Most likely the Great Firewall is blocking the DHT connections? Any suggestions?

@dukedorje that error is just about local dns, it's not supported in all networks. try running

> ipfs swarm peers

Since we are at this:

1) We should set up some nodes with frequently white-listed TCP ports as bootstrap nodes to bypass simple firewalls. 5223 for example (previously jabber now also apple push) is a great candidate IMHO.

2) What is the status of relay between ip4 and ip6?

yeah, running a node on 443 and/or 80 would be nice too.

I'll have him try that! Gonna check out some more writings on IPFS to get a firmer technical grounding. Anywhere you'd suggest to start for learning about the IPFS DHT and how swarming works?

@dukedorje that error doesnt mean that things dont work. He should still be able to share content just fine, have him check the output of the command ipfs swarm peers and make sure hes connected to a bunch of people.

I am in PRC. Everything is working fine. IPFS can penetrate the GFW.
