How to show opened ports on my desktop (widgets)

**sowhat123456789a** · September 18th, 2009

I look for kde-look.org but I could not find anythink about it. I want to see on my KDE (4.x) desktop the ports which are opened. If there is no a widget I can do it with conky or screenlets ?
There is any widget like "active ports" software on windows? Can you help me?

Thank you!

do you mean network ports? some display like this command?

Code:

lsof -i

I don't know of any widgets that can do this specifically, but the STDIN plasma widget can display the output of any terminal command. So it can show the output of the above command. See here:

netstat -tapn and sudo lsof -i is nice idea but they stop after 10 seconds from terminal. I want to see them always updated.

Have you actually tried that plasma widget I suggested?

you can set it to update as often as you want. I set the timer for 10 seconds and use this command:

Code:

kdesudo -i question -c "lsof -i"

I had not saw your meesage sorry...

I try to install STDIN plasma widget but I could not

First i gave these commands :
mkdir build
cd build
and than :
cmake .. -DCMAKE_INSTALL_PREFIX=`kde4-config --prefix`
but this give me an error :
-- The CXX compiler identification is unknown
CMake Error: your CXX compiler: "CMAKE_CXX_COMPILER-NOTFOUND" was not found.Please set CMAKE_CXX_COMPILER to a valid compiler path or name.

Also when I write your second commnand on terminal, it gives me the results after 10 seconds and than stops (as always).

you need to install a compiler

Code:

sudo apt-get install build-essential

i think there are also kde-specific dev packages required. cmake will notify you of this if you try running it again after installing build-essential. I've attached a deb package I built from svn a few months ago, which you could use instead of compiling your own. It's a 32-bit checkinstall build, so won't work if you're running 64-bit.
