Subject: ip_conntrack vs netstat


> Hello,
>
> When comparing the output of /proc/net/ip_conntrack with the "netstat"
> command, I'm seeing a few established connections in ip_conntrack that are

> But if this was the case there should be some connections to unknown hosts
> showing in ip_conntrack as well so I should be able to rule out that

> Now for my question:
> Can anyone confirm that ip_conntrack can show "ghost" connections like
