Comments on: Firestarter Firewall for your Ubuntu Desktop

For one if this Firewall is going to be supported or used in Ubuntu than it should be configured to auto start with boot in the installation of Firestarter.

Relating all to users in previous posts and than having new users reading the posts will do nothing but totally confuse them. Even Linux operating systems need a firewall but having a firewall which requires a user to start it each time they boot or reboot is inane. I use both openSUSE and Ubuntu and openSUSE installs a firewall on installation of the operating system so why cannot Ubuntu do this? What good is Firestarter if it does not install with a auto start up at boot??

I should have added that the following simple script:

fileName=$(ifconfig -v ppp0 |grep “inet addr” |cut -d: -f 2 |cut -c 1-15 )
touch /home/zapper/Desktop/$fileName

adds a file named by my ip-address to the desktop on UBUNTU 8.0.4.

Firestarter won’t start when I use a ppp0 to GPRS connection, which is my only alternative here in the Andes mountains. I am not happy with an open connection and no firewall.

Errmsg: “Failed to start the firewall
The device ppp0 os not ready.”

Does Firestarter use netmanager, which has a known bu re. ppp0?

Is there a work-around?

try doing this:

export EDITOR=gedit && sudo visudo

Now you need to add the following line in /etc/sudoers file

#ruchi ALL= NOPASSWD: /usr/sbin/firestarter

Replace “ruchi” by your the name of the user or the group which can use sudo and do the modification.

Now you can test this using the following procedure

sudo - K

gksu /usr/sbin/firestarter

When it try to open it should not prompt for password

but i’m still prompted for the password.
(this worked for me)

I hope the following might be of interest:

I just installed feisty on a box, installed firestarter, ran the gui and added some stuff to be blocked etc and I clicked the “ip address is assigned via dhcp”. The firewall works fine until I reboot - after reboot there is no protection at all.

Now, it seems like firestarter created a file

/etc/dhclient-exit-hooks

just containing just the line

sh /etc/init.d/firestarter start

However, it seems like ubuntu is configured to look for this file in /etc/dhcp3 (I’m not quite sure about this) *or* to look for executables in /etc/dhcp3/dhclient-exit-hooks.d/ (I think it will run them all after dhclient obtains an ip.)

Anyway, here is a FIX to get a persistent (firestarter configured) firewall to be activated after reboot (i.e., when getting ip via dhcp):

Rename

/etc/dhclient-exit-hooks

/etc/dhcp3/dhclient-exit-hooks.d/firestarter

and then make it executable (using chmod +x).

Is this is a bug in ubuntu?

There seems to be a bug in /etc/sudoers. Use this link, it worked for me.

Try this as your session command:
gksu /usr/sbin/firestarter

Keep up the good work. =)

From my understanding firestarter should start up as a service no?

I was trying as root. Just tried to run it as normal user, without the sudo, and now a popup tells me I must have administrative privileges…

Another question is, can I make firestarter run at boot for all users of my pc, even if they’re not in the admin group?

All hints and ideas appreciated.

are you trying to run this program as normal user or root

sometimes if you are trying to run as root you will get this error.

I’ve search all over the ubuntu forums and search engines for the way to start firestarter at boot, all with identical instructions, but right after editing the /etc/sudoers file, and testing it, I get this message in the terminal:

Xlib: connection to “:0.0″ refused by server
Xlib: No protocol specified

(firestarter:5803): Gtk-WARNING **: cannot open display:

the numbers after “firestarter:” change at random when trying it again, still I don’t know what that means. Any ideas to get this working?

I’m using ubuntu edgy and firestarter 1.0.3
