I have configure my /etc/sudoers, like that:

Cmnd_Alias QEMU=/sbin/ifconfig,/usr/sbin/brctl
admin   ALL=(ALL) ALL
admin   ALL=NOPASSWD:QEMU


So if someone run qemu, it will use sodu to run ifconfig and brctl.

my question is: when I configure no mattler like above or as bellow: 

#!/bin/sh
echo $* >> /tmp/qemu-ifup.$$
/sbin/ifconfig ${1##/*/} 0.0.0.0 promisc up
/usr/sbin/brctl addif bridge ${1##/*/}

the script will run when use root. But when not use root or sudo, the
script won't run. I don't know why. ( the script: 
"echo $* >> /tmp/qemu-ifup.$$"  can tell me whether the script was run)
