ipx and apache (maybe OT, maybe hole)

Hi everyone! Maybe this one is off topic but I am not sure... We have a SuSE box acting as a webserver. Now I noticed during one of our regular nmaps that ipx ports is open. But: gw:/usr/src/linux # grep IPX .config # CONFIG_IPX is not set The other day I noticed somehting like rpc-sometime or similar. I immediately did stop all not 100% necessary processes and this one did vanish. Maybe this belongs to our tests with Sybase?! Any hint appreciated, Christian
