TCP keepalive packets in wireshark
SUMMARY
I couldn't help but notice in Wireshark that my KDE Neon workstation and my
phone exchange 12 TCP keepalive packets per minute. Such a rate doesn't seem
reasonable at all and I am concerned that it drains my phone battery for no
good reason.
STEPS TO REPRODUCE
1. Pair KDE Connect on a workstation to a phone.
2. Start Wireshark on the workstation.
OBSERVED RESULT
12 TCP keepalive packets per minute between the workstation and the phone.
EXPECTED RESULT
No TCP keepalive packets. Or configurable TCP keepalive interval, with an
option to disable keepalive completely.
