Stage 1 - Multi-hop payments

After having opened the channel between Charlie and Bob, mined the funding tx (I generated 3 block instead of just 1), created the invoice as Charlie, when I try to send the payment from Alice to Charlie I get the following error:

{
	"payment_error": "unable to find a path to destination",
	"payment_preimage": "",
	"payment_route": null
}

If I send a payment from Bob to Charlie, by having an open payment channel between them, the send payment works as expected.

Cannot run lnd in light client mode

I am going through the installation but cannot get lnd to run on neutrino.

How can I get this to work?

As the instruction says, this is the command I executed:

lnd --bitcoin.active --bitcoin.testnet --debuglevel=debug --neutrino.active --neutrino.connect=faucet.lightning.community

Here is my log:

lnd --bitcoin.active --bitcoin.testnet --debuglevel=debug --neutrino.active --neutrino.connect=faucet.lightning.community

2017-10-19 18:57:21.280 [WRN] LTND: open /home/t4sk/.lnd/lnd.conf: no such file or directory

roasbeef/btcd doesn't have a makefile

The installation documentation says when installing btcd, use make btcd, but that repository is missing a makefile. Are we suppose to use glide now instead of the make command?

[Installation] Tests fail because btcd not found

In the installation documentation, after installing lnd, it suggests to run the test via ...

go install; go test -v -p 1 $(go list ./... | grep -v  '/vendor/')

But these tests fail (multiple times) due to btcd not being installed yet (haven't reached that part of the installation docs yet). So it seems like an order of operations problem. If its agreeable, i can move the tests to later part of the documentation in a PR, if that makes sense to others.

=== RUN   TestFilteredChainView
--- FAIL: TestFilteredChainView (0.28s)
	interface_test.go:759: unable to set up mining node: exec: "btcd": executable file not found in $PATH
FAIL
exit status 1

I've confirmed that installing btcd does make the tests pass.

Here is the full output of running the tests on my machine.

go install; go test -v -p 1 $(go list ./... | grep -v  '/vendor/')                                                  ✓  15.55  10:07:42

Stage 1 - Payment channel is not switching when intermediaries of one channel doesn't have sufficient funds in multi-hop payment channel

Scenario: We were trying multi-hop payment from A to C
A opened a channel of 50000 satoshis with B (local balance: 40000, remote balance:0 with respect to A)
B opened a channel of 80000 satoshis with C (local balance: 70000, remote balance:0 with respect to B)
A opened a channel of 90000 satoshis with D (local balance: 80000, remote balance:0 with respect to A)
D opened a channel of 55000 satoshis with C (local balance: 45000, remote balance:0 with respect to D)
Available channels:
A -----> B ------>C
A -----> D ------>C
Now, C added an invoice of 20000 satoshis.
A----->D----->C channel was randomly selected for multi-hop payment
Balances was updated on A ------>D------->C
In A -----> D; A: 60000 and D: 20000
In D -----> C; D: 25000 and C: 20000

Again, C added an invoice of 30000

Expected result:
Now, channel A----->B----->C should be used to settle this payment because D doesn't have sufficient funds.

But we are getting this
{
"payment_error": "unable to route payment to destination: TemporaryChannelFailure",
"payment_preimage": "",
"payment_route": null
}

At the end there is link to stage 2 that is broken.

`make check` fails due to missing bitcoind daemon

This bug seems like a regression of #9

When running make check in the "Installing lnd" section of the installation documentation, i get some failures due to a missing executable, bitcoind.

=== RUN   TestFilteredChainView
--- FAIL: TestFilteredChainView (0.49s)
	interface_test.go:896: Testing 'bitcoind_zmq' implementation of FilteredChainView
	interface_test.go:901: unable to make chain view: exec: "bitcoind": executable file not found in $PATH

Stage 1: lnd flags need updating

In the commands starting alice, bob and charlie's nodes, several flags and their corresponding breakdowns need to be updated (rpclisten --> rpcport, restlisten --> restport, change btcd to bitcoin and AFAIK remove --bitcoin.node=btcd)

think it should be:
lnd --rpcport=10001 --listen=localhost:10011 --restport=8001 --datadir=test_data --logdir=test_log --debuglevel=info --no-macaroons --bitcoin.simnet --bitcoin.active --bitcoin.rpcuser=kek --bitcoin.rpcpass=kek

Question about using Jeykll vs Hugo

Hi there, just a stupid question: is there a reason why, even if you know golang so well, you used Jekll instead of Hugo as a website static generator?

Theme?

Hi!
Love your theme!where did you get the jekyll theme(I would like to use it for my website if it's alright for you guys)?

Stage 1 - Finish up the P2P network by connecting Bob to Charlie

Everything works until I submit the command to create the connection between Charlie and Bob:

charlie$ lncli-charlie connect <BOB_PUBKEY>@localhost:10012
[lncli] rpc error: code = OutOfRange desc = EOF

But if I reverse the connection as:

bob$ lncli-bob connect <CHARLIE_PUBKEY@localhost:10013

the connection can be establish and I can even request Bob's and Charlie's listpeers:

bob$ lncli-bob listpeers
{
    "peers": [
        {
            "pub_key": "02015fed2386ff28ad68499490a6fcec2b7550441a3e5ecf3008da23019c21b722",
            "peer_id": 1,
            "address": "127.0.0.1:57734",
            "bytes_sent": "539",
            "bytes_recv": "539",
            "sat_sent": "0",
            "sat_recv": "0",
            "inbound": false,
            "ping_time": "218"
        },
        {
            "pub_key": "030099902bed3d20b94650fba598e82baaa27344f65c889b3098a7e046b4adab5b",
            "peer_id": 2,
            "address": "127.0.0.1:10013",
            "bytes_sent": "201",
            "bytes_recv": "201",
            "sat_sent": "0",
            "sat_recv": "0",
            "inbound": true,
            "ping_time": "318"
        }
    ]
}

and

charlie$ lncli-charlie listpeers
{
    "peers": [
        {
            "pub_key": "037a644510a712e0eb82992989f2979cb6020aa55dac2129d7b52900eabd53cdfa",
            "peer_id": 1,
            "address": "127.0.0.1:57828",
            "bytes_sent": "253",
            "bytes_recv": "253",
            "sat_sent": "0",
            "sat_recv": "0",
            "inbound": false,
            "ping_time": "226"
        }
    ]
}

Stage 2 - Incompatibility with Stage 1

lncli-web requires --noencryptwallet boolean flag and certificates compatible with NodeJS/gRPC.

Wrong macaroonpath in the developer tutorial.

Background

In the developer tutorial on https://dev.lightning.community/tutorial/01-lncli/index.html in the section Working with lncli and authentication, the command to create and get info of a wallet has the wrong macaroon path. It has the path --macaroonpath=data/admin.macaroon instead of the right path: --macaroonpath=data/chain/bitcoin/simnet/admin.macaroon:

Your environment

version of lnd: 0.5.0 beta
which operating system (uname -a on *Nix): Ubuntu
version of btcd, bitcoind, or other backend: 0.12.0 beta

Steps to reproduce

Follow the tutorial on https://dev.lightning.community/tutorial/01-lncli/index.html. In detail the commands:
lncli --rpcserver=localhost:10001 --macaroonpath=data/admin.macaroon create
lncli --rpcserver=localhost:10001 --macaroonpath=data/admin.macaroon getinfo

Expected behaviour

Create Wallet
Get information about the lightning connection.

Actual behaviour

[lncli] unable to read macaroon path (check the network setting!): open data/admin.macaroon: no such file or directory

Notes

This issue is a duplicate of the one on the lnd repository: lightningnetwork/lnd#1891

btcd fails to run due to leveldb missing

I get to the following place in the documentation and a get the panic, which is outlined in Roasbeef/btcd#27.

btcd --testnet --txindex --rpcuser=cbarraford --rpcpass=password                                                  2 ↵

No where in the installation doc does it mention a requirement of leveldb needing to be installed. Is that a mistake of the documentation or did i compile something wrong on my local box?
