New Antminer S17 Pro arrived today and plugged it in. It boots up, I can access the web UI, I set my pool, and I set it to "Low Power" mode for testing. After hitting apply, the fans spin up -- similar to the S9 -- and I'm expecting to start hashing about 30 seconds later. Instead, after about 60-70 seconds, the red "Fault" light on the machine starts blinking. Fans keep spinning, web UI still works fine, but it's not hashing. I've verified that it has an internet connection using the network diagnostics tool in the Antminer Web UI. And the pool isn't down because I have other S9s hashing on it right now.

If I put it in "sleep mode", the fault light turns off -- although it still isn't hashing. Trying to set it to Low or Normal power mode causes the blinking again about 60-70 seconds.

I captured the entire kernel log here: https://gist.github.com/tjwebb/8f75822baf28f346110ffca359790364. I don't see any obvious failures there, but any insight is appreciated.

Around the internet, I see considerable interest in mining through a VPN to protect one's privacy. For example, it's reasonable that you may not want unencrypted mining traffic to be observable by your ISP or others outside your home network. But there are some common concerns:

- Increased latency between miner and pool
- Increased costs/complexity of running your own VPN
- Unsure of the correct way to implement a VPN solution to guarantee security

If a mining pool had a low-latency VPN attached to the same network as the stratum server and full node, what is the level of interest in mining with a pool that supported this?

I got the same email. Seems legit. LOL

Also, excuse me while I move all my coin out of coinbase...

The US dollar is the world's reserve currency. If everyone starts "dumping" it, what are they going to trade if for? bars of gold? bitcoin? The reality is that if the dollar becomes suddenly worthless, so does just about everything else, including your life to anyone with a gun who wants your stuff.

> why is it ok for a group of people calling themselves the government to force everyone to buy their services?

If you are in a country that allows you to vote, then you are the government. In most countries, you are free to leave. You can go to a country that doesn't collect taxes. Somalia, for example.

At the end of the day, if you know where your single point of failure/entry is, it is that point that you should secure to whatever degree is feasible in your situation. Web servers unfortunately have tons of attack vectors available.

Yea that's what I thought. You should only ever open the cgminer API to a particular IP address that you control or trust. Otherwise, someone with a port-scanner can find your miner and take control of it.

Awesome. I think we're building some similar stuff, let me know if you'd like to collaborate. Make sure to file issues if you run into them. I'm actively maintaining this project, so I'll make sure to fix them as soon as possible.

Arithmetic isn't subject to someone's opinion. It is hard to generate bottom-line profits with mining *in the short term*, and that's even if you're very good. You need very cheap electricity, and enough capital to invest in the best hardware. Mining might be profitable for some, and unprofitable for others.

But long-term, mining is an investment in the transaction volume of the bitcoin network, not in your machine's ability to out-pace the electricity/difficulty/hasrate trifecta. Difficulty could be 10x what it is now, but if transaction volume is 1000x higher, then even those old Antminer S1's might be profitable again.

Mining is a long-term bet on the transaction volume of the bitcoin economy. The large players are poised to benefit over time as the transaction fees paid to miners rises with transaction volume. Short term, you're just happy to break even on electricity. But If you have the capital to burn while you wait for the tipping point of transaction volume, it'll be worth the wait.

You will never mine even 0.0001 BTC with a graphics card or CPU.

If you're just experimenting, you can get an older ASIC machine on ebay for cheap.

Cool, but I'd expect the power efficiency to be better. I guess the main benefit is decreased noise?

0.0000 is not valid JSON at all, for anything. It should just read 0.0.

My workaround is here, so you can see: https://github.com/hashware/node-cgminer-api/blob/master/lib/client.js#L105. I have to manually replace "nan" with 0, otherwise JSON.parse() fails.

Crazy unicode character showing up in cgminer "stats()" response: https://github.com/hashware/node-cgminer-api/issues/10#issuecomment-59324280

Maybe its a Antminer thing, but cgminer shouldn't let invalid JSON be returned.

Is this good advice? What's keeping someone else from taking control of the miner?
