SUMMARY I was looking at my machine's journal as one does when my eye caught this message repeated several times in the same second: Feb 15 21:57:53 ioniq kdeconnectd[2714]: kdeconnect.core: CompositeUploadJob::startListening() - Error opening a port in range 1739 - 1764 Checking the open ports, I find this: mdione@ioniq:~$ netstat -tpln | grep kdeconn tcp6 0 0 :::1716 :::* LISTEN 2714/kdeconnectd tcp6 0 0 :::1750 :::* LISTEN 2714/kdeconnectd tcp6 0 0 :::1751 :::* LISTEN 2714/kdeconnectd tcp6 0 0 :::1748 :::* LISTEN 2714/kdeconnectd tcp6 0 0 :::1749 :::* LISTEN 2714/kdeconnectd tcp6 0 0 :::1746 :::* LISTEN 2714/kdeconnectd tcp6 0 0 :::1747 :::* LISTEN 2714/kdeconnectd tcp6 0 0 :::1744 :::* LISTEN 2714/kdeconnectd tcp6 0 0 :::1745 :::* LISTEN 2714/kdeconnectd tcp6 0 0 :::1758 :::* LISTEN 2714/kdeconnectd tcp6 0 0 :::1759 :::* LISTEN 2714/kdeconnectd tcp6 0 0 :::1756 :::* LISTEN 2714/kdeconnectd tcp6 0 0 :::1757 :::* LISTEN 2714/kdeconnectd tcp6 0 0 :::1754 :::* LISTEN 2714/kdeconnectd tcp6 0 0 :::1755 :::* LISTEN 2714/kdeconnectd tcp6 0 0 :::1752 :::* LISTEN 2714/kdeconnectd tcp6 0 0 :::1753 :::* LISTEN 2714/kdeconnectd tcp6 0 0 :::1742 :::* LISTEN 2714/kdeconnectd tcp6 0 0 :::1743 :::* LISTEN 2714/kdeconnectd tcp6 0 0 :::1740 :::* LISTEN 2714/kdeconnectd tcp6 0 0 :::1741 :::* LISTEN 2714/kdeconnectd tcp6 0 0 :::1739 :::* LISTEN 2714/kdeconnectd tcp6 0 0 :::1764 :::* LISTEN 2714/kdeconnectd tcp6 0 0 :::1762 :::* LISTEN 2714/kdeconnectd tcp6 0 0 :::1763 :::* LISTEN 2714/kdeconnectd tcp6 0 0 :::1760 :::* LISTEN 2714/kdeconnectd tcp6 0 0 :::1761 :::* LISTEN 2714/kdeconnectd So there must be a bug where kdeconnect somehow opens multiple ports. STEPS TO REPRODUCE To be hones, all I can say is that kdeconnect has been running for days if not months. I almost never close my session or reboot the machine.
