You probably need to disable this code in sys/kern/kern_exec.c temporarily: /* * Turn off syscall tracing for set-id programs, except for * root. */ if (p->p_tracep && suser(p->p_ucred, &p->p_acflag)) { p->p_traceflag = 0; vrele(p->p_tracep); p->p_tracep = NULL; } -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
