Did you setup the Neo_cli with rpc as the guide "NEO-CLI Node Deployment"? would you please show the the net state via "netstat -apn" in you ubuntu?

[timmetje21]

thx for helping! when i submit the command dotnet neo-cli.dll /rpc, its seem to be working fine but when i use the command 'show node' its giving me: neo> show state Height: 0/4477/42000, Nodes: 0

output after using 'netstat -apn'

while using /rpc launch the neo-cli there will be one socket listening the port 20332(neo testnet， mainnet is 10332) such as: `$ netstat -apn|grep 10332

(Not all processes could be identified, non-owned process info will not be shown, you would have to be root to see it all.)

tcp 0 0 0.0.0.0:10332 0.0.0.0:* LISTEN 3475/dotnet `

so would you please try again? submit the command "dotnet neo-cli.dll /rpc", then launch another terminate to submit netstate, if still not find the 20332, try disable the firewall using "ufw disable", if it worked , maybe you will wait the neo sync the block, `neo> show state

Height: 0/1231166/1231166, Nodes: 3`

[timmetje21]

hi sir, thanks for the respond again, I have rebooted ubuntu, went through all the steps again. when i use the command netstat -apn, i can clearly see its connection altho not port 20332?

very strange, it still seems the RPC service not startup, would you please show me the neo-cli configure file and submit the command history to show me the result? thanks

[timmetje21]

sir, it is possible from a virtual machine right? here u go tim@tim-VirtualBox:~$ cd Downloads/neo-cli tim@tim-VirtualBox:~/Downloads/neo-cli$ dotnet neo-cli.dll /rpg NEO-CLI Version: 2.7.1.0

here tim@tim-VirtualBox:/Downloads/neo-cli$ dotnet neo-cli.dll /rpg it should be rpc not rpg

[timmetje21]

ur the man....gosh i feel....bad....

[malcolmturnballs]

If you're doing this on Windows, you need to replace the contents of config.json with config.testnet.json. The instructions saying you don't have to, but I think it's only applicable to Ubuntu.

How long does this part take? I've been waiting up to 10 minutes now and nothing has moved.

[pigxo]

you can get the off-line data from http://static.neo.org/client/chain.acc.zip, then unzip it into TestChain folder

[timmetje21]

I managed to setup the wallet, thx for the help. Altho i kept getting an error 'Failed building wheel for scrypt', not only me but there were others aswel. I have fixed it by apt-get install libssl-dev

Not sure if this error is common, if it does it should be included in the trinity user guide!

[timmetje21]

@malcolmturnballs i have made an user friendly guide. https://medium.com/@timajax5/user-friendly-tutorial-setting-up-trinity-service-node-deployment-with-ubuntu-16-04-34d566077dcc Not sure if its any helpfull but for the not-so-tech people could be helpfull

[malcolmturnballs]

On Windows: Had this step running for hours - still nothing :( The results of show state: Height: 0/1244133/1244133, Nodes: 10

Got this error when I stopped running Neo: requests.exceptions.ConnectionError: HTTPConnectionPool(host='localhost', port=2 0332): Max retries exceeded with url: / (Caused by NewConnectionError('<urllib3. connection.HTTPConnection object at 0x041BE3F0>: Failed to establish a new conne ction: [WinError 10061] No connection could be made because the target machine a ctively refused it',))

[timmetje21]

Mmm looks like the same error i had, u sure u run the /rpc command?

[malcolmturnballs]

yeah definitely with 'show state', is it okay that one of the numbers are still showing 0? (0 / 1244133 / 1244133)
