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)
