compiling LPFW (Leopard Flower Personal Firewall) -> cannot execute binary file

booo123 · December 26, 2013, 10:33am

Hey,

I’ve been trying to compile LPFW for a while now without success, so I’m seeking for some help here
I downloaded the latest v.0.4 sources from Leopard Flower | Free System Administration software downloads at SourceForge.net and followed the Install instruction:

mkdir build
cd build
make -C …/ DESTDIR=pwd

Here the complete output:

Now, the compilation works fine but the lpfw binary is somehow not executable:

sudo: ./lpfw: command not found
boo@boopc:~/Downloads/lpfw-0.4-src/lpfw-0.4-src/build> chmod +x lpfw
boo@boopc:~/Downloads/lpfw-0.4-src/lpfw-0.4-src/build> sudo ./lpfw
./lpfw: ./lpfw: cannot execute binary file


boo@boopc:~/Downloads/lpfw-0.4-src/lpfw-0.4-src/build> file lpfw
lpfw: GCC precompiled header (version 014) for C

Unfortunately, I dont even know what exactly is the problem, so I really appreciate any help. Thanks in advance!

Are you aware that openSUSE has a firewall already? Is there any particular reason you need to install LPFW instead?

booo123 · December 26, 2013, 11:20am

Yes, I know that Opensuse has a firewall, but is there also the possibility of configuring (easily) per-application rules?

lpfw is not executable. Why don’t you show the results of ‘ls -l’? Be sure to wrap it in CODE tags.

Here it is:

It looks like you have a Python GUI and a CLI. Try ‘./lpfwpygui’.

booo123 · December 26, 2013, 12:01pm

I guess you are right, but I tried to follow the instructions:

SIMPLE CONFIGURATION:

Make sure lpfw,lpfwcli, and lpfwpygui are in the same folder

In a terminal window navigate into the folder where lpfw is located and launch “./lpfw” as root

In a terminal window of an X session navigate into the folder where lpfw is located and launch “./lpfwcli” or “./lpfwpygui” as a regular user (not root). You will see the frontend.

And the second point fails, or do I miss something?

chief_sealth · December 26, 2013, 12:18pm

I’m not clear on what this lpfw is. It’s identified by file as a header, but in the information you provide it should be an executable. I take it you’ve read the README and the INSTALL files? That should usually get you started.

booo123 · December 26, 2013, 12:23pm

Yes, I followed the INSTALL and README files. Is it possible that Its somehow related to the error which occurs when I execute the make command without root rights? Why is gcc unable to find the header file when not executed as root?

booo123 · December 26, 2013, 12:53pm

Thanks for your help!
I solved the problem. Somehow, all netfilter libraries have been installed like this:

/usr/include/libnfnetlink-1.0.1/libnfnetlink/*.h

But the headers themselves and also LPFW expects them to be in

/usr/include/libnfnetlink/*.h
so, I copied the folders directly into the include folder and then the compilation worked successfully with root rights and the resulting files where proper executables.
