Loading Dynamic Libraries

Some Linux API require the use of updated libraries. A common example is gethostbename command that is not thread safe. Attempting to run this with a old glibc while the network is down or with a null parameter will result in a segmentation fault. In order to see what libraries your executable is dependent upon use ldd executatble name. In order to make your executatable use an updated version of glibc, you might need to update your library path via export LD_LIBRARY_PATH=/lib/686
