Moving Domains

Moving domains is a messy process. It requires changing urls and settings up messy changes. Here are three quick documents to make that process simpler before you go scouring the web,. Keep in mind these guides are specifically for WordPress users.

If you are using a webserver like Nginx, you can setup 301 Redirects from your old domain as follows, edit /etc/nginx/conf.d/youroldwebsite.conf

Otherwise just add the following to your .htaccess file, somewhere in that file

Finally login to Google Webmaster console, go to Search Console, click on your website, go to the top right “gear” -> Change of address and select the new website that you added in the search console. This will help to redirect all traffic from your old website to your new website.

Uninstall go-ethereum on Centos 7 / Linux

To uninstall go-ethereum

run the following, first start by deleting the huge blockchain off your server:



Delete the Data Directory

  • Mac:
  • Linux:
  • Windows:

Make sure you delete it recursively! Meaning make sure the keystore folder under ~/.ethereum is deleted as well so your wallet data is deleted so no one can steal. Likewise make sure you have backup of it on your local machine to receive and transfer funds.

Next let’s delete the previous symbolic link we made during installation
Here is my previous symbolic link:
ln -s /go-ethereum/build/bin/geth /usr/local/bin/geth

First unlink it:


Then delete the rest of the installation here:



How to Mine Ethereum on centOS 7

Mining on centos7 seems to be a labor and existing guides are outdated or hard to find. Here is one updated and written for our times. Keep in mind, using this will consume 10s of GB of disk space, this is because the whole block chain, has to be downloaded.

Make sure you have git installed:
yum install git
git clone
cd go-ethereum
make geth
The full command to start geth will look something like this
/go-ethereum/build/bin/geth account list

Use a symbolic link so you can use geth without the long filepath
ln -s /go-ethereum/build/bin/geth /usr/local/bin/geth

The command below should now work
geth account list

It will not return any result because you don’t have any accounts created or imported. If you don’t have a ethereum address, then you can create a new one by typing geth account new

If you do have an account already create a new file and paste the unencrypted private key like so as shown below:

Create a new file named “pass”
touch pass

Edit that file, you can use any editor, i use the editor nano
nano pass
paste the unencrypted key, Ctrl+X to save and exit it.

Now have geth import that file with its key
geth account import pass

Now make sure that account is imported:
geth account list

Protect the unencrypted pass file, don’t ever let anyone touch it or lose it
chmod 700 pass
Chmod prevents other users from using it or seeing it.

Then start mining:
geth –mine –minerthreads=2

Now I recommend installing screen and running it in a screen so you can use the terminal for other business or run geth in the background using the & flag.

For screen
yum install screen

Then mine and hold ctrl + A + D, this will detach the screen but keep it open

You can return to that screen session by typing
screen -r

That’s it!

Split-Tunnel Cisco AnyConnect Secure Mobility Client & IBM AT&T Global Network Client VPN

So you have Cisco AnyConnect Secure Mobility Client and IBM AT&T Global Network Client VPN and you need to use both? Well have no fear, you can use both. In your windows, right click the Cisco AnyConnect Secure Mobility Client, then “Open AnyConnect”, from there click on the gear on the left side in the GUI to open up settings. In the Settings dialog menu, go to Preferences tab and check “Allow local (LAN) access when using VPN (if configured). This close the dialogue, disconnect from both VPN and reconnect to Cisco AnyConnect then IBM VPN and you should be able to use both.
