I am trying to use https://github.com/kesar/ethereum-php on the back-end of my web site.
I followed a tutorial http://iotbl.blogspot.ca/2017/03/setting-up-private-ethereum-testnet.html to set up two local chains on Ubuntu Server 16.04.
This is what geth version prints:
Geth Version: 1.8.2-stable Git Commit: b8b9f7f4476a30a0aaf6077daade6ae77f969960 Architecture: amd64 Protocol Versions: [63 62] Network Id: 1 Go Version: go1.9.4 Operating System: linux GOPATH= GOROOT=/usr/lib/go-1.9
This is how I start the chains:
geth --nodiscover --verbosity 9 --networkid 50000 --port 50000 --datadir Chain01/ console
geth --nodiscover --verbosity 9 --networkid 50000 --port 50001 –datadir Chain02/ console
I am able to add a peer inside terminal for chain2 and command
net.peerCount displays 1 as expected.
With that working I tried to go through https://github.com/kesar/ethereum-php/blob/master/README.md and ran into a timeout. This is my PHP code:
$client = new EthereumClient('http://127.0.0.1:50000'); $iBlockNum = $client->eth()->blockNumber() ;
This is what I see in the geth’s log:
TRACE[03-08|15:56:06] Accepted connection addr=127.0.0.1:43610 TRACE[03-08|15:56:11] Failed RLPx handshake addr=127.0.0.1:43610 conn=inbound err="read tcp 127.0.0.1:50000->127.0.0.1:43610: i/o timeout" TRACE[03-08|15:56:11] Setting up connection failed id=0000000000000000 err="read tcp 127.0.0.1:50000->127.0.0.1:43610: i/o timeout"
This is what wireshark shows as being sent from port 43610 to port 50000:
but port 50000 does not reply.
One other detail I am debugging in Eclipse oxygen. Not sure whether it can affect the interaction.
Another thing: the php code above works fine when I connect to http://truffleframework.com/ganache/.
