A few minutes ago I noticed the activity lights on my switch were blinking like mad. I knew that there was nothing I was doing that should cause the network activity, so I checked my processes to see if someone had connected to my httpd/ftpd and was downloading something. Nothing there. So I ran a `netstat -f inet` and saw that there was a TCP connection to cookies.cmpnet.com in the FIN_WAIT_1 state. I launched a program from ports called "trafshow" and saw that my machine was actively transfering data with cookies.cmpnet.com, so I checked netstat again, but still only one connection to cookies.cmpnet.com in the FIN_WAIT_1 state. This network activity went on for about 5 minutes on my DSL connection - many megabytes must have been transfered. I've since found that it appears to be something related to Opera, but even killing Opera didn't kill the rogue TCP connection. This brings me to my question: is there any way, through a shell, to kill a socket that apparently has no proccess associated with it?...It seems that this scenario should never happen? I can reproduce this problem simply by reloading the questionable page in Opera. Any ideas, thoughts? By the way I'm running 4.6 Stable cvsuped and built about a week ago -also, Opera for Linux v6.01.
