pppoe-start as user

Janusz11 · 09-29-2005, 03:19 PM

Can someone please tell me what I have to do so that I can start and stop my internet connection via "pppoe-start" and "pppoe-stop" as a normal user.

At the moment I can start and stop my internet connection only as root.

I don't know about running at as a normal user, but (in my mind) the easiest and safest method would be set up sudo to allow a normal user to run the commands.

So you would do

Code:

sudo pppoe-start

run 'visudo' to change the access rights for users in the /etc/sudoers file.

I have mine start at the machine start-up since it is unlimited anyway.

Here is how my /etc/rc.d/rc.pppoe looks like:

Code:

#!/bin/bash
#
case "$1" in
   'start')
      /usr/sbin/pppoe-start 
      /usr/sbin/pppoe-status ;;
   'stop')
      /usr/sbin/pppoe-stop 
      /usr/sbin/pppoe-status ;;
   'restart')
      /usr/sbin/pppoe-stop 
      /usr/sbin/pppoe-start
      /usr/sbin/pppoe-status ;;
   *)
      echo "usage $0 start|stop|restart" ;;
esac

And I insert the following into beginning of /etc/rc.d/rc.inet2

Code:

##
## Modified by carboncopy to startup ADSL
##
if [ -x /etc/rc.d/rc.adsl ]; then
    echo "Connecting to YOUR_ISP_NAME: pppoe-start"
    /etc/rc.d/rc.pppoe start
fi

Why did I set it up in /etc/rc.d/rc.inet2 because of this line:

Code:

# At this point, we are ready to talk to The World...

You could just include the few lines above into /etc/rc.d/rc.local instead. Probably the correct way of doing things.

Thanks for your help!

Unfortunately, putting meself into the sudoers file didn't help. I tried different combinations, like

Code:

 
ITS_ME ALL=NOPASSWD:/usr/sbin/pppoe-start
ITS_ME ALL=NOPASSWD:/usr/sbin/pppoe-stop

and

Code:

ITS_ME ALL=(ALL) /usr/sbin/pppoe-start
ITS_ME darkstar=(ALL) /usr/sbin/pppoe-start

The result is always the same: first I have to be at /usr/sbin so that the command "sudo pppoe-start" could even be recognised and then I get the following error message:

Code:

Sorry, user ITS_ME is not allowed to execute 'pppoe-start' as root on darkstar.

But your script carboncopy was of great help to me! I finally managed to get access to the internet without root privileges. And that's how I did it:

1. I created a script with parts of carboncopy's code called "adsl" at /usr/local/bin, which I made executable with sudo privileges

2. I made it executable by all users, but only editable by root:

Code:

chown root.root /usr/local/bin/adsl
chmod a+rx /usr/local/bin/adsl

3. Put the following line into /etc/sudoers:

Code:

 
%users ALL=(ALL) /usr/local/bin/adsl

And now I can start and stop my internet connection with "sudo adsl start" and "sudo adsl stop".
This is how the script looks like:

Code:

#!/bin/sh
# Script /usr/local/bin/adsl

SUDO="/usr/bin/sudo"

# start script by sudo when
# not started by root
if [ -x $SUDO -a $UID -ne 0 ]; then
    exec $SUDO $0 $*
fi

case "$1" in
   'start')
      /usr/sbin/pppoe-start ;;
   'stop')
      /usr/sbin/pppoe-stop ;;
   'restart')
      /usr/sbin/pppoe-stop
      /usr/sbin/pppoe-start ;;
   'status')
      /usr/sbin/pppoe-status ;;
   *)
      echo "usage: $0 start|stop|restart|status" ;;
esac

Thanks again!
