Closed csunny closed 6 years ago

csunny commented 6 years ago

Hello, I meet some mistake when i run multiple node.

Node A 

2018-11-30 17:38:32,641 - kademlia.network - INFO - Node 410271437375177868241350581552805887836623615468 listening on 0.0.0.0:8468

Did not received reply for msg id b'r+uBvXlcuyTQsB1WhRhEX7hzPxg=' within 5 seconds

when i run get and set I can connect A or B, but when i set a value in A, It can't get in the node B. I am confused, somebody can explain this to me ?

Can you attach the code you're running with exact steps to reproduce? I already see something suspicious - the third line of Node A's logs:

2018-11-30 17:38:40,002 - kademlia.protocol - INFO - never seen 127.0.0.1:8469 before, adding to router

Port 8469 isn't being listened to on Node A (port 8468) or Node B (1234) - so I suspect you had another node running before on 8469 and then turned it off - which is why it won't respond to a message.

@bmuller 👍 Yes， just as your say， I run multiple node test successfully. Thank you so much.
