Protect Your Mining & Node Centos 7 Servers With Fail2Ban

So you just received a bunch of credits from a VPS provider and you want to start mining or simply host a node. A simple way to protect your new Centos 7 mining and/or node server is to install Fail2ban to prevent SSH brute force attacks to guess your root password. This article isn’t about top notch security and I realize that you can disable root login and/or disable password login. This is for those that simply want decent security while still maintaining root login with password. Continue reading “Protect Your Mining & Node Centos 7 Servers With Fail2Ban”

The Immaturity of Cryptocurrency Communities

Reddit is about the best place you can go to right now if you are interested in Cryptocurrency. If you have a coin you are interested in, chances are there is a subreddit dedicated to that coin where you can subscribe and ask questions.

The problem with a lot of these subreddits is the immaturity of the overall member base that submits content. I spend a lot of time in /new/ down voting pump and dump style posts, immature meme and misspellings trying to be cute (what the hell is this HODL shit anyways?)

Potcoin Wallet Not Syncing Solution

Edit: I no longer hold Potcoin due to lack of developer interest in maintaining a quality coin. The nodes that I have run have now been shut down. See this for more help:  https://www.reddit.com/r/potcoin/comments/75xpmi/cant_access_wallet_because_wallets_not_syncing_at/

As it sits now, when you download the Potcoin Wallet it will not sync. This seems to be an issue with the Potcoin peers.dat file that is installed with the Wallet. To get around this you can either update the peers.dat file itself or use the console to manually add nodes.

I run three Potcoin Nodes and they will remain up 24/7/365. So I will walk you through adding my nodes to your Wallet via the console. This is on a Windows machine but it should work with any wallet console.

Open your Wallet and then go to Help > Debug window.

In the Debug window click the Console tab and then enter the following commands, one at a time pressing enter after each:

  • addnode 45.33.29.45 add
  • addnode 139.162.4.29 add
  • addnode 172.104.102.113 add

It will look like this before and after:

 

After a few minutes your Potcoin Wallet should begin syncing with the rest of the nodes. If you found this helpful, consider a donation!
