Possible security issue

Folks, 

Been experimenting a bit with nc. As such, I've been seeing how it
connects from system to system. To that end, I started an Apache server
on my laptop (on Hardy Heron). After a bit, I ran the following command
to see if the nc from another system would show up.

netstat -atun 

Well, it didn't, but I soon got a bunch of entries similar to 

tcp  0  0 10.168.0.111:44535    xxx.yyy.zzz.aaa:80   ESTABLISHED

Where xxx.yyy.zzz.aaa are public addresses from places like FL and MA.
It's not like I have anything but the standard "It works" page on that
Apache server. 

And I have a pretty standard (though old) firewall on the router, with
port forwarding set up (for the most part) to some non-existent systems
on my local private IP net. My laptop is not one of them. 

So there's a weakness somewhere. I don't have MS running anywhere (at
the moment) Any suggestions on where I should look?

Thanks,
Mike

Just to follow-up, I tried some of the IP addresses from the remote
sites in my browser, and most of them go to fake Google home pages. I'm
guessing they're looking for other places for their phishes. The fake
Googles are pretty slick, even error pages from their IP addresses are
carefully done.

parallel processing cluster solution

I need to build a cluster for parallel processing (i.e. not high
availability). It will run MatLab and SPM. Is LinuxPMI a good solution? I am
naturally drawn to it because OpenMosix was cool, and I'm really leaning
toward open source. Thankfully, Linux has been mandated by the customer.

Any experience with Oracle GridEngine? It gets a mention in an email from
the customer. Either they know what they're doing, or they totally don't.
I've been meaning to build a cluster as a learning exercise for some time
now, but unfortunately I have never gotten around to it. So my hands-on
knowledge is lacking. I could use some backup for my argument that an open
source solution would be better than the Oracle product.

Um... I think that probably is Google.

PDP-8 emulator

FYI:

http://www.sparetimegizmos.com/Hardware/SBC6120-2.htm

Build your own PDP8e!   With blinky lights and boot loader
toggle switches!

It interfaces with an IDE laptop drive, so a 2GB drive
emulates a thousand 2 megabyte RK-05 disk packs.  Imagine,
an entire room of 1970s capability in the palm of your
hand!

With only 32k memory, it won't run Linux without a LOT
of swapping.  A challenge for hard core geeks.

KDE apps on Gnome

Fedora 11 x86_64, up to date, with Gnome desktop. 

Everything works, including the KDE apps that I have installed.
However, the window menu font in the KDE apps is too large - nearly
twice the size of the window menu font in other applications. By "window
font" I mean the font used for "File, Edit, View," and other
app-specific menus. The title bar is using the same font as other apps,
so the window manager (Metacity) appears to be doing its job. For some
reason the KDE apps are ignoring the Gnome settings for default
application menu font. 

I have looked everywhere for a control panel for KDE, but cannot find
it. Of course, why would there be a KDE control panel when I am using
Gnome? Maybe the installation of the KDE apps failed to add something
needed to control the KDE application menu display.

Any suggestions welcome.

On my centos box /usr/bin/kcontrol was provided by  kdebase.

Thanks. But it didn't work. I installed kdebase, but kcontrol was
apparently not included.

I searched in Yumex for "KDE, settings" which turned up some
possibilities, one of which was kdebase-workspace. But when I tried to
install it I got a message that it was "removing for dependencies"
several things, including ktorrent. Ktorrent is what I plan to replace
Vuze with, so that won't do. Ktorrent is also one of the KDE apps with
huge fonts. Then I looked more closely and realized it was also going
to remove kdebase-workspace. Apparently it was already installed.
(There is a bug in Yumex which makes it fail to display installed apps
in a different color.)

I tried several of the other possibilities yielded by the search, but
they were either already installed, or were tools to go the other
direction, that is, to make Gnome apps work correctly in KDE.

I also tried the KDE main page, where I found a link to KDE forums.

It also occurred to me to try "locate kcontrol." This yielded a couple
pages of files and folders. However, all appear to be help files or
icons. None seem to be a configuration tool.
