Execute EXEC or SHELL as a root
 

Hello, can i execute this line:

sudo ln -b /dev/ttyUSB0 /dev/ttyS0

From gambas in a virtual terminal/consol, without it ask me the root's password???

I tried like this:

EXEC ["sudo", "ln", "-b", "/dev/ttyUSB0 /dev/ttyS0"] WAIT

and this

SHELL "sudo ln -b /dev/ttyUSB0 /dev/ttyS0" WAIT

and it doesn't work.... plase someine Help ME!!! =)

sudo does not ask for the root password.

What did you define in /etc/sudoers?

1. YES! it asks password.

2. I tried everything =(
in /etc/sudoers i tried to give permision like this:

user_name ALL=(ALL) ALL

and also:

unser_name ALL = NOPASSWD:/dev/ttyUSB0 /dev/ttyS0

and it doesn't work..... Please HElp Me !!! =)

Good. Do you see any "Defaults targetpw" in the file?

This makes no sense, as you have to specify the granted command, i.e. /bin/ln, therein instead. But the first rule you mentioned should do already.

but not root's, it asks for the user password :P
