[help] wannabe miner

[siggie]

hello to all,
after a while my btc matured enough and I can now afford to start mining 

I just have some doubts I hope you can help me clarify.

I plan to get an AvalonMiner 741 used, since the price is very appealing.

I need a static IP to mine right? I plan to get the NoIp service and use a router with openwrt or ddwrt.

Do I need a normal internet connection or can I use a 4G router like this one, that as lan and wlan ports too and comes with openwrt?

The avalon miner has a raspberry as a controller, is it possible to make it run through tor? This is the only topic I found
https://bitcoin.stackexchange.com/questions/3608/pool-mining-through-the-tor-network
I really would like to torify, or is a vpn enough?

I am still researching a lot, but these are the questions the puzzle me the most.

You do not need a static IP to mine and since the network traffic that is generated by a miner is not really that much, a 4G router should work fine. I am not sure why you would want to use the TOR network, that could potentially be problematic due to latency issues and such. You don't need a VPN either unless you need to access your miner remotely. If you are managing the miner remotely, having a static IP would make life easier for you.

thanks for the reply,

I was thinking to use TOR, because I am used to use it for pretty much anything I do on the net.  Plus I read here
https://bitcoin.stackexchange.com/questions/3608/pool-mining-through-the-tor-network
this:

mostly something that came up during a conversation I had with my academic supervisor - he likes pointing out all possible exploits that could happen in relation to Bitcoin and one of them was attacking miners based on their IPs. So I figured out I'd investigate possible obfuscation of the addresses.

is just a paranoid person, or it could actually happens?

Here Satoshi stated that is not possible to connect the ip to the wallet
https://bitcointalk.org/index.php?topic=8.msg34#msg34
but is it possible to connect the IP to the miner? I want to mine for fun atm, but what if the country I live in in 10 years wakes up and tell me: you bought a miner, you should have earned this, now pay me. Where I live is not unlikely that something like this happens. I do not want to avoid taxes, if it turns out I can make a profit while helping the bitcoin network, then I'll gladly expand to business level, but I just want to avoid possible future problems.

There is no sole proprietorship where I live, opening a business costs at the lowest level 4000usd of taxes per years even if you do not earn anything so is not like I really have a choice here.

I would like to have remote access to the miners so I'll go with a vpn + static ip

I really believe too that cryptocurrency can help change the world for the better, like internet did, so I am very happy after years of lurking to have the chance of mining.

Miners can and will be attacked if they have direct connections to the Internet. You need to put the miner behind a firewall and have the public IP on the firewall and the miner on a private IP behind the firewall. This will protect it against potential threats. You can then use a VPN to the firewall to remotely manage the miner. I do not recommend using TOR - too much latency and potential for problems.

Good luck with your project. I am glad to help if I can.

thanks for the suggestions,
I'll drop the TOR idea then.

Do you think that the firewall of openwrt or dd-wrt is enough? Should I look for something else?

Can I ask what do you use?

Anyway I'll document my progresses here for the next geek with the same problems.

[SGMPhil]

Just about any good firewall will do, personally I use a Sophos XG firewall - works great and has good VPN support. If you have a spare computer with 2 ethernet ports on it, you can build one using the "home" version (link below) of the software at no cost. Otherwise, you can always buy a hardware appliance but that costs money and you have to license the software. Sophos makes a great platform and it is very secure.

thank you!!!

Of course I can not give you merit but I'll tip you once I start mining. Sound fair to me.

Yesterday I looked into a RPI router, I'll leave the links here if anyone is interested.

Bitcoin has so much potential, I really would like to see how they would do all the bribery and illegal trafficking on a public blockchain and the best part of this technology is that like the internet could shape this world for the better pretty fast.
