Hi, Can someone please help, Everytime i enter "sudo service fr24feed status" the following shows with green circle, looks good, however when i enter "fr24feed status" i have errors within the readout, and every 5 seconds a audible error ping is produced when ssh into raspberry pi 2 from my windows 7 pc using putty. I installed using the fr24 image. I am not sure if mlat works, but know that data is fed to the fr24 servers and is active. But what is causing these errors. Any help/clarification would be greatly appreciated.

Thank You
