Is my Relay@Home Working?

When your relay starts up the first thing it does is verify it’s database. It then starts sycronizing the blockchain with all the other relays on the network. If your relay has been powered off for a while it may take several hours to retrieve the blockchain history. While it is getting back in sync it will not be active on the network.

Check status on Public Peer List

Once your relay is syncronzied to the blockchain you can check for it to be listed on the public peer list.
If you see your IP address listed on this page then your relay should be operating correctly and helping with the security of the network!

The public IP address of your relay will be the address assigned to you by your internet service provider. You can find your your public IPv4 address by logging into your modem/router or by going to this site: https://www.whatismyip.com/what-is-my-public-ip-address/

Updating Software on Relay@Home

Regular software updates are important to ensure the security and performance of the blockchain you are supporting. Keeping your Relay up to date is very important.

At this time we have not created an automated remote update process due to the complexity of the blockchain and privacy issues. Blockchain upgrades are typically a straightforward and simple process.

Your will need to connect to your Relay using SSH protocol. I use Putty on windows for SSH access however Windows 10 now has a built in SSH client available via the windows command prompt. MACos and Linux have built in SSH clients as well.

The upgrade instructions below assumes you are familiar with SSH access however please contact us if you need instructions on how to do this.

SSH into your relay. Your computer needs to be on the same local network as your Relay. The firewall on the Relay blocks SSH access from outside of your local network.

Follow the upgrade instructions specific to your network:

ARK Upgrade

Change to core-ark folder
cd core-ark
Pull updated files from github
git pull
Rebuild. This will take several minutes
yarn setup
Restart relay process and open log file
pm2 restart all && pm2 logs

When the relay process starts up it must verify the existing database and several other tasks. This operation is very memory intensive and will likely take 10->25 minutes. The Pro Relay@Home version has faster memory and will complete this step much faster than the standard version.

When you get the message Blockchain 100% in sync, the relay is running with updated software and should be visible on the peer list. https://www.friendsoflittleyus.nl/ark-network-stats/

Compendia Upgrade

Download and update files. This will take several minutes to complete
ccontrol update core
Restart relay process and open log file
ccontrol restart relay && ccontrol logs

When the relay process starts up it must verify the existing database and several other tasks. This operation is very memory intensive and will likelytake a few minutes. The Compendia blockchain is much smaller than Ark and will startup much more quickly as there is less database to verify.

When you get the message Blockchain 100% in sync, the relay is running with updated software and should be visible on the peer list. https://www.friendsoflittleyus.nl/compendia-network-stats/
