LibNetBlock



LibNetBlock (LIBrary for Blocking Network access) is a library which partially (read below for limitations) ensures that no program under its control can use the network. LibNetBlock does this by intercepting calls to some C library functions and replacing them by its own substitutes.

Requirements for compiling:

Type ./configure to configure the library for your system.

If you want to enable the public interface of LibNetBlock, configure the library with ./configure --enable-public-interface.

The public interface is compatible with SWIG, so you can make native bindings to LibNetBlock for any supported language.

LibNetBlock allows some programs to be banned (not allowed to run under LibNetBlock, because they might need accesss to the network). One banning file is always supported - ${sysconfdir}/libnetblock.progban (${sysconfdir} is /usr/local/etc unless set otherwise during configure).

If you want to disable additional banning files pointed to by environment variables, configure the library with ./configure --enable-environment=no

If you want to disable additional banning files in users' home directories, configure the library with ./configure --enable-user-files=no

Type make to compile the library.

Documentation comes complied (and can be copied right away), but can be changed and recompiled, if you have the makeinfo program (texinfo package).

Type make install to install the library. Read the docs on how to make the library running.

Type info libnetblock (after installation) or info doc/libnetblock.info (before installation) to get help.

RPM dependencies:

THE LIBRARY HAS BEEN TESTED, BUT IT MAY NOW OR LATER CONTAIN ERRORS, WHICH MAY LEAD TO INCORRECT PROGRAM BEHAVIOUR. READ THE LICENSE FOR A WARRANTY (THERE IS NONE).
