#17 Program - Unknown TCP

v1.0 (example)


Let me first say THANKS for this program really nice!

I hope this project is going to continue on for some time...

Since there's isn't Little Snitch for Linux this is the next best thing!

Ok, when I ran 0.8.0 it says 'root unknown TCP' and I'm assuming this isn't a bug since this only supports IPv4 and when using WiFi that has IPv6 built in, then this is the typical response back, saying the TCP is unknown?

I also have VMware installed showing two adapters; vmnet1 & vmnet8 showing inet6 as well...

Since IPv4 is only supported and I'm assuming again that since these adapters have IPv6 support that Nethogs reports this, then hopefully you can remove this from a newer version so it's not showing this?

Here's a screen shot, it's 0.7.0, but 0.8.0 does the same;

    Sorry I should of just put up a screen shot of 0.8.0 because I saw a problem with the window;


    Where I put a small 'DOT' below 'Total' on the lower left, part of the section for some reasons comes sticks down...

    Thanks again...

    I think IPv6 traffic is simply ignored and doesn't show up at all.

    The 'unknown TCP' line is normal: it collects all TCP traffic that we were unable to relate to any actual process.

    Well should it be able to relate this to some process or it just can't?

    Having it say Unknown seems kind of strange, like we don't know what is going on, also it seems scary like we have something going on that we do not know anything about.

    Maybe this can be changed in the future, so the end-user doesn't feel lost/uncertain about what is going on...

    I hope you understand what I mean? To say to me, 'unknown' is like saying I don't know and since people are using this as a type of security tool, it's also like saying I don't know what is going on...

    I improved this a bit and when using CVS you should really not be seeing anything else than '0' traffic for the 'unknown TCP' process. It might disappear completely in the future.

    Actually, IPV6 traffic is not ignored, we can look up the source code.

    I think I need several days to check the code. So if I know how to deal, I will tell you
