The skywire network has under gone some updates! That means it’s time to update your miners. Here is my quick and easy guide on how to get ready for the new testnet.

Currently the easiest way to get back online is to re-flash the microSD cards on your Pis and then update your node keys in your whitelist application.

As of writing this, there are a couple problems with the updating procedure. Later versions of Windows (7 and 10 confirmed) cannot flash the SD cards with Skyflash, so it is recommended to use a third party application such as BalenaEtcher. Also, the new discovery address is currently not accepting new connections, so you may not be able to get back online at this moment. I will post an update as things progress.

Skyflash:

Windows: https://github.com/skycoin/skyflash/releases/download/Skyflash-v0.0.6/Skyflash_Skyflash-v0.0.6_windows_amd64.exe

OSX: https://github.com/skycoin/skyflash/releases/download/Skyflash-v0.0.6/Skyflash_Skyflash-v0.0.6_osx.tgz

Linux: https://github.com/skycoin/skyflash/releases/download/Skyflash-v0.0.6/Skyflash_Skyflash-v0.0.6_linux_amd64.gz

I will be running Windows 7 to update my nodes.

Step 1

Download your version of Skyflash from the correct link above. Make sure you have at least 18gb of storage available, as you will need space to save the images that will be flashed onto the microSD cards.

Double click the executable to open Skyflash.

Click Download to download a copy of Skybian.

Once that is done, you should see the tool like below.

If your router is configured for the previous official images or built by Crypto Kings, you can use the Skyminer defaults. If you need to make networking changes, you can do that all in Skyflash by unchecking Use the Skyminer’s defaults.

Once you are happy with the network settings, click Build the images.

It will prompt you if the default directory is an good install location. This is where you need at least 16GB of space to store the image files.

When you are happy with the location, click okay and Skyflash will start building your images.

If you are running Linux or OSX, you should be able to use Skyflash to flash the images onto your microSD cards. Under Windows we will be using BalenaEtcher.

Step 2

Download BalenaEtcher

Install the program and start it.

Click Select image and navigate to your Skybian image files. Select the Skybian-manager.img file and click open.

First, turn your skyminer off. Then, take the first( or Top) microSD card out of the Pi and and plug it into your computer. You may have a laptop with a media hub, a dedicated USB microSD card reader, or if you have an SD card slot you can get a microSD to SD card adapter. Even a digital camera with a microSD card will work, just plug the card into your camera and the camera into your computer.

A microSD to SD card adapter

BalenaEtcher should detect the drive when you plug it in. Double check it is the correct drive, as any data on the selected drive WILL be lost in the flashing process.

Finally click Flash!

BalenaEtcher will flash the microSD card with the selected image and then validate it at the end.

When it is complete you will see the following screen.

Unplug your microSD card and plug it back into the Skyminer.

Click Flash Another and begin the entire process again, working your way through the Skybian image files and your microSD cards. I like to only remove 1 microSD card at a time and flash it so I don’t lose track.

Because we have only changed the files on the microSD cards, if you have set-up a bookmark to the old manager page, it should still work for the new one! If not, you can check Step 6 of my DIY Skyminer Build Guide which describes how to set that up.

Step 3

When you navigate to the Skyminer Manager page, it should prompt you for a password.

The default password is:

1234

It will then ask you to create a new password, and then re-login using it.

Once that is done you should see something like this.

If you are missing nodes in the list, first thing to try is delete your cache/cookies/site data. This can be done by going into your browser settings, Privacy/Security settings and deleting your cache. NOTE: You can delete the cache just for the manager page if you search for it in the list.

Give the miner 5–10 minutes to boot all nodes, delete the cache and check again. You should see all nodes online.

If you are missing nodes, you can use the manager terminal or a computer terminal to login to the missing node using SSH.

Usage:

ssh root@IP_ADDRESS

Password for the default skybian images is :

skybian

Useful commands when troubleshooting:

ps aux | grep node → Shows if node process is running

ps aux | grep manager → Shows if manager process is running

ping IP_ADDRESS → Checks to see if another Pi is online in the network

You are almost done!

You still need to update your node keys in your whitelist application.

Step 4

Navigate to whitelist.skycoin.com

Login with your e-mail and password.

Click the edit button to the right of your miner (the pencil).

NOTE: Your node key list may not load immediately, just give it a minute and it will populate.

Click the X’s beside each of your old node keys to delete them.

At the top of the node list click the + to add a node.

Go back to your manager page and click on the first node.

Click on the Public Key and it will copy it to your clipboard.

Paste this into your Nodes list for Node 1.

Click the + sign at the top to add another Node and repeat the same steps with the next node Public Key.

Once you have added all 8 node keys, double check them. When you are satisfied, click the Submit button at the bottom of the list and you’re done!

Currently the Skycoin discovery address is not accepting new connections. So when viewing an individual node, if you click on the Discovery button, it should display the new testnet address:

testnet.skywire.skycoin.com:5999-028ec969bdeb92a1991bb19c948645ac8150468a6919113061899051409de3f243

If it also says your Node is not discovered, be patient and wait for an update from the Skywire team. You can get the latest updates on Telegram, via the Skywire PSA channel https://t.me/SkywirePSA
