You can use the following to identify also the services that use those ports and see if there is something suspicious:
Code:
netstat -tupl
You didn't say your distro, but from the listening ports and sockets of the netstat output, I guess you're running KDE on whatever distro it is, so it's normal to see various strange ports and/or port ranges open.
Please use "code tags," which become available when you click the "Go Advanced" button under the compose post window, when posting the output of terminal commands or posting text files.
As I get further reacquainted with Linux, I'll tend to feel better about unknowns and oddities that are in fact processes simply doing their jobs. I have gone ahead and installed Rkhunter - updated and added a tcp package that let's it see into hidden ports, etc. Fun stuff. Cheers.

Rep:
When I was first learning Linux I looked at everything thoroughly; log files, dmesg, printk, netstat, etc, just so I would know what a normal system looks like. You can also run 'unhide' every so often. Run every type of test. I've found systems with a hidden process corresponding to every visible process, basically controlled by a malware hypervisor.
