KASSIBER(1) General Commands Manual KASSIBER(1) NAME kassiber -- Inject an executable from the FreeBSD host into a jail SYNOPSIS kassiber [-h] [-a] [-A] [-n] [-r rtld] [-p path] [-l lib] [-j jail] [-c chroot] cmd [arg ...] DESCRIPTION The kassiber command opens the runtime loader and an executable, loads the required libraries, attaches itself to a jail and/or chroot direc- tory before executing the loaded command. The following options are available: -h Print the usage message and exit. -a Infer the required libraries using the runtime loader's tracing support. Put inferred libraries before manually specified li- braries. -A Infer the required libraries using the runtime loader's tracing support. Put inferred libraries after manually specified li- braries. -n Don't infer the required libraries. Only manually specified li- braries will be loaded. -r rtld Override the the default runtime loader path. -l lib Manually specify a library to preload. Can be specified more than once. -j jail Specify the jail to attach to. The command attaches to the jail before it chroots itself. -c chroot Set the chroot directory path. The command chroots itself after it attached to the jail. CAVEATS Many programs rely on access to further files besides just their linked libraries so will be unable to function usefully from within the jail. EXIT STATUS The kassiber command exits with EX_NOINPUT, EX_OSERR, or EX_CONFIG on errors otherwise it replaces itself with the invoked executable.
