If you have questions about the output of this command, update your question to include the output. For TCP traffic, the Zscaler service drops all packets that match the rule. Consider running sudo netstat -tnp (the -p will show the process associated with each connection the sudo is necessary in order to see processes that aren't owner by your current user). Filters define the traffic information that you view in your Firewall Insight. There's not enough information here to make that determination. Logging of this sort of information is up to specific applications (e.g., for a web server you would probably have some sort of access log, while something like ssh will by default log to the system log). There isn't really a general answer to this question. But it merely maintains such a list without actually pairing, so there shouldn't be any security issues at this point. Kdeconnect, which scans for available devices to pair in a local network. ![]() Update: As per the suggestion of I found that these connections are established by If this indicates any possible insecurity, what should I do? Also, I have rebooted several times and these connections always seem to pop up automatically. Is this a sign of network attack? Since I don't remember using any service that would need a tcp connection from the same subnet. Where can I find the logs for these connections, e.g., who initialized the connections and how they are allowed/authorized (if this is the right word)? The other two unknown ip do come from the same subnet, but I have no idea why these connections are opened. Proto Recv-Q Send-Q Local Address Foreign Address State When doing some network security checks (on which I am an amateur) for my office PC, I discovered a few unknown tcp6 connections (with netstat -nt): Active Internet connections (w/o servers)
