Startup script access right

fhleung · 07-23-2007, 02:50 AM

I put iptables script in /init.d in ubuntu and update the runlevel with
update-rc.d filename defaults
The script with system command iptables inside.

1 how can I start up the script when non-root users login? Now the things can not procede when user and password entered.

2 how can I login as root to delete the script file? I can not login from the default menu session. Can I login from failsafe text mode? Using installation disk seems not help.

Thank you for help.

Lets get this clear, you put the iptables commands for your firewall in a script (lets call it firewall.sh) mhich you moved to the directory /etc/init.d so the command to start your firewall would be

sudo /etc/init.d/firewall.sh

If this is correct, then you need to add the line:

/etc/init.d/firewall.sh

...to the bottom of your /etc/rc.local file. Then it will start at boot every time regardless of the user.

Thank you for the help Simon,

The firewall.sh file in /etc/init.d/ and also in /etc/rcX.d
I could add the path to the bottom of /etc/rc.local file.

My question should be, what is the update run level update-rc.d for

No... you add the filename and path to that file. Not the whole file!

And take it out of all those rcX.d directories... it don't belong there.

You gotta boot to a rescue image from the grub menu. If that dosn't work, use the live CD.

Note: you shouldn't use a root account in ubuntu anyway.
(Surely the root login gets as far as the password too?)

I put my iptables script and executed inside the rc.local

When I run the rc.local script, either in
etc/init.d/rc.local and /etc/rc.local

there were
Permission denied and
Permission denied (you must be root) messages.
