The pipe code has been drastically rewritten. Where is the child hanging? Look at the WCHAN message in a ps -alx output. Also, there's ktrace, this might help you to find out what system calls the child has already done. Finally, you can compile passwd with -g debugging symbols, and run gdb on it. gdb can now also attach to a running process, and will stop the process as soon as it attaches. -- 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. ;-)
