Today I was sitting around and by chance happened to notice that my machine had traffic of ~5 kB/s (up and down), but I was not doing anything to initiate this. So I checked the network connections:
Code:
njl@dvorak:~$ netstat -tup
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)
Active Internet connections (w/o servers)

And there I found some mysterious SSH connections to appsrv2.masternursery.com on various ports. I then killed the SSH processes and the network traffic stopped.
What is going on?
(Debian etch, linux 2.6.18, KDE, etc etc)
