Run a script automatically upon user login?

FastFeet · 05-21-2009, 02:14 AM

I am running Mythbuntu 9.04. I am using a Dlink DWA-130 USB WiFi adapter. In order to use it I need to run the following script as root/sudo. Is it possible to run this script automatically (root/sudo) upon my automatically loging in to my user account?

Here is the Script:

Code:

#!/bin/bash

# Select NIC type
card=RTL8192u

SYSTEM=`uname -r|cut -d. -f1,2`

if [ $SYSTEM = 2.4 ]
then
cd ieee80211
insmod ieee80211_crypt-rsl.o
insmod crypto-rsl.o
insmod michael_mic-rsl.o
insmod aes-rsl.o
insmod ieee80211_crypt_wep-rsl.o
insmod ieee80211_crypt_tkip-rsl.o
insmod ieee80211_crypt_ccmp-rsl.o
insmod ieee80211-rsl.o

#insmod 
case "$card" in
        "RTL8192u")
        cd ../HAL/rtl8192u;
	insmod r8192_usb.o;;
        "RTL8190p")
        cd ../HAL/rtl8192;
        insmod r8190_pci.o;;
        "RTL8192e")
        cd ../HAL/rtl8192;
        insmod r8192_pci.o;;
        *)
        echo "Unknown NIC type"
	;;
esac

else
cd ieee80211/
insmod ieee80211_crypt-rsl.ko
insmod ieee80211_crypt_wep-rsl.ko
insmod ieee80211_crypt_tkip-rsl.ko
insmod ieee80211_crypt_ccmp-rsl.ko
insmod ieee80211-rsl.ko

#insmod
case "$card" in
        "RTL8192u")
        cd ../HAL/rtl8192u;
	insmod r8192_usb.ko;;
        "RTL8190p")
        cd ../HAL/rtl8192;
        insmod r8190_pci.ko;;
        "RTL8192e")
        cd ../HAL/rtl8192;
        insmod r8192_pci.ko;;
        *)
        echo "Unknown NIC type"
	;;
esac
fi

cd ../..
ifconfig wlan0 up

Can't you put the script in
/etc/rc.local ?

No, I have not had any luck with doing that.

I have copied the script to /etc/init.d/ and made it executable. Then I did a "sudo update-rc.d wlan0up 100 2 3 4 5 ." and then rebooted. No luck.

However if I run the script after fully logging in I have no problems. At that point Network-Manager and everthing else is fully loaded. So I assume I need a way to automatically launch the script once I am fully logged in, which is set to happen automatically. It is a Myth-Box after all. I was really hoping someone might have some incite on to how to run the script automatically once netowrk manager was fully loaded or something.

USB Wireless for Linux is so painful!

Thanks for any help you can offer,

You can put the script in your .bash_profile to run when you first log in, even if the login is automatic.

To prevent the script from running with successive logins, you can have it check to see if it is already running, or restrict the script to run only when logged in to a particular console, etc.

For example:

Code:

if [ -z "$DISPLAY" ] && [ $(tty) == /dev/tty1 ]; then
flux
fi

In this case, a user is automatically logged in via tty1 upon boot up, and a fluxbox session is begun.

cheers,
