I've just stopped all pretty much all services except sshd on my server (Ubuntu Server 10.04), and when I run iftop I get output that looks like this:
12.5Kb 25.0Kb 37.5Kb 50.0Kb 62.5Kb

This is the first part (not the unix socket part) of the output of netstat -a:
Active Internet connections (servers and established)

What could all those strange connections on port 21095 be? And why would they not show up in netstat?? Any advice would be greatly appreciated.
