need help running a shell program on startup as root in a terminal

bolter40k · 08-04-2010, 11:36 AM

Hi,

I am running Linux Mint 9

I play xbox live and run it through my laptops wireless network connection so i dont have to pay 100 dollars for the usb wireless adapter for the xbox. In windows 7 this is easy to configure so that when i turn my laptop on and then xbox it automatically connects. I wrote a program that enables ip forwarding it is written as follows

Code:

#!/bin/bash -e
ifconfig eth0 up
ifconfig eth0 192.168.2.0
echo "1" > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -o wlan0 -s 192.168.2.0/24 -j MASQUERADE

but when i run it as root nothing happens and my xbox wont connect to live. But when i manually type in these commands after su to root it works

also my startup file is rc.local as ive read an in it ive written the path to my program so it will be run how can i tell it is being run and how do i tell it to run as root?

Code:

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
/home/dylan/xboxlive.sh

thanks, bolter40k

May be it's because bash -e exits right after a command returns a non-zero value.

It will run as root. If you are really suspecting that rc.local is not being run, try echoing something from there, like echo hello > /tmp/hello .

Does your script work if you run it from a terminal, as root, after the computer is fully booted? If so, then may be your desktop environment (which, I guess, starts up after rc.local) is messing up your card settings.

well for some reason my script doesnt work when run by itself (right click>open as admin) doesnt seem to work at all
I cant seem to figure out where i went wrong especially considering when i enter these commands in myself it always works

What are the permissions of your script?

What if you run it like this:

Code:

cd
su
./xboxlive.sh

May be your DE is messing with the card? What does /sbin/ifconfig output look like after you boot?
