Run locally without internet connection

[roughpandaz]

@avahowell This package require Ants to connect through the public internet.

Is there a way to run this locally without any internet connections? Currently, I get the error no UPnP-enabled gateway found, which seems to be a result of this configuration.

If not, is there any options for running a local testnet just to play with the sia API?

Thanks in advance.

I've got it running locally but get the error message:

However, it seems to be mining and creating blocks. Full output below.

Additionally, how should I get this to run on AWS? I run the file with the command

go run sia-antfarm/main.go sia-antfarm/antfarm.go sia-antfarm/ant.go -config nebulous-configs/basic-renter-host.json

However, I get this output, even though I opened the specific ports and enabled outgoing and incoming TCP connections.

Hi @RongxinZhang,

no UPnP-enabled gateway found

this is more of a warning than an error. Sia will try to automatically forward the ports it needs, and it also uses UPnP to discover its external IP address if necessary. AWS (and most VPSs) don't sit behind a UPnP-enabled gateway, but their ports will be open so it's a non-issue. In the case of a local router, you can forward the ports manually and it should work fine.

2018/05/25 11:58:10 error clearing upnp ports for ant: goupnp: SOAP request got HTTP 500 Internal Server Error: ...NoSuchEntryInArray

this is another benign warning that you can ignore. It means that Sia tried to un-forward a port, but the port wasn't forwarded in the first place. Unfortunately UPnP is one of the worst protocols ever designed, so the error message is both extremely verbose and minimally helpful.

error creating antfarm: exec: "siad": executable file not found in $PATH

The antfarm uses whatever version of siad you installed. So you need to make sure you build siad before running the antfarm.

@lukechampine Ahh ok, that's helpful!

@lukechampine Regarding setting up a contract locally. After running the test net, I am able to ping the network using localhost:9980 to post a job via CURL

# post contract
curl -i -A "Sia-Agent" -X POST "localhost:9980/renter?funds=1000000000000000000000000000&period=4320"
# reponse
HTTP/1.1 204 No Content
Date: Sat, 26 May 2018 16:56:16 GMT

However, no miner seems to accept the contract. As a result I get the message

# post file
curl -i -A "Sia-Agent" -X POST localhost:9980/renter/upload/qux/bar.txt?source=/Users/roguepanda/Desktop/webdraft4c.jpg

# response
HTTP/1.1 500 Internal Server Error

{"message":"upload failed: not enough contracts to upload file: got 0, needed 1"}

This is my config:

{
    "antconfigs":
    [
        {
            "jobs": [
                "gateway"
            ]
        },
        {
            "jobs": [
                "host"
            ],
            "desiredcurrency": 100000
        },
        {
            "Name": "renter",
            "jobs": [
                "renter"
            ],
            "desiredcurrency": 100000
        },
        {
            "apiaddr": "127.0.0.1:9980",
            "jobs": [
                "gateway",
                "miner"
            ]
        }
    ],
    "autoconnect": true
}

Bump to this. I'm also able to setup an Ant farm locally, but more than half the time contracts will never form. Blocks are being mined though, and I'm also able to mine blocks myself.

Is there a way to force or speed up contract creation?

[roughpandaz]

@acejam can you connect to the host's API and ping the /host route.

If the host's connectabilitystatus = false, then in the renter's host_db, this specific host's acceptingcontract = false. Then it is not possible to create a contract.

Basically, it looks like if you don't have a static IP which allows for incoming and outgoing connections then the renter will not form contracts with hosts.

If this is not the case, please correct me as this is what I have discovered so far.
