Here is a repost from a few days ago.
Hi Everyone,
I have some good news about the Supernode servant. We have our first update. The biggest news now is that the bandwidth has been lowered to 5Mbps.
I have some instructions.
1) Turn off your servant. Rename your servant folder you used to boot the servant until now to “Old Servant” or something like that.
2) Go into the servant folder and find a file called config.properties. Copy this and paste it unto your desktop. Next rename this file config-user.properties. (you will need this new config-user.properties file shortly)
3) Please download the new servant from
https://drive.google.com/folderview?id=0B_0Z9jDGHPxPVmdCVDFTT25CXzg&usp=sharing124) Unzip the folder. Open the servant folder and paste in the file you named config-user.properties.
5) Your NIS should be still running. If not, start it. And also you need to restart your servant. To start the servant double click on runservant.bat in the servant folder (In Mac or Linux navigate to the file in terminal and use the command sh startservant.sh). If it works you will see your terminal/command prompt window become active.
6) Lets now double check to see if your servant is working correctly. Please go to http://
:7880/nr/metaData, e.g. http://211.107.113.107:7880/nr/metaData4, in your browser. If everything is working okay, you can see something like
{
"application": "Servant",
"publicKey": "cd94cdcfde6878e093bc70e35b575dbe68095c69f73112e67559f71c1fb64c6e",
"version": "0.0.4-alpha"
}
7) If all went well you can now delete your old servant folder.
If you have any questions you can review the instructions at the top of this thread, or please just ask.
Thanks!
