Firewall in Ubuntu 8.04 live boot?

win_to_lin_migrant · 05-18-2009, 09:25 AM

Is there a firewall in Ubuntu 8.04 live boot? If so does it run in live boot? TIA

Code:

sudo iptables -L

.. will give you your answer.

Thanks but I don’t have it booted right now and I was hoping someone here might have a simple yes or no answer to one or both of my questions.

Sorry no. Live booted Ubuntu 8.04 gave unhelpful reply to unhelpful command as in:

Code:

Unknown arg '-l'

Still waiting for simple yes or no answers to simple questions in my OP from anyone who knows. TIA

"Unhelpful command"? I think not.

Did you go to primary school?

Did you ever learn that there is a difference between CAPITALS and lower case?

Linux gave you the answer to your problem: "Unknown arg '-l'"

That means that it doesn't understand the "minus lower-case-"ell"" you gave it.

Try again.

You are getting answers, but it seems you cannot read or understand them.

If you have a removable drive, firestarter may be loaded prior, and run from the drive when mounted.

I've done it, and it's easy...USB key, deb 32 or 64 bit pkg, then just pop it in. THEN hook up.

IMO one disadvantage of a CLI as opposed to a GUI it that human beings can make typos that result in errors.

Even with proper case the output of that command is just as unhelpful as before especially considering that all I ever asked for were simple yes or no answers to my questions. Sigh.

I don’t think it’s realistic to expect help from you considering your level of hostility towards me. Thanks but no thanks.

Thanks but I don’t want a firewall. I wanted to know if the default Ubuntu 8.04 in live boot already has one running.

"Spoonfeeding" people is tedious. You are expected to be able to do a little research for yourself. I gave you the right pointer, but here goes:

Code:

tgar@vaio:~$ sudo iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination
tgar@vaio:~$

1] The above means that iptables is installed and ready to use, but as there are no policies Listed, it is not doing anything. Ie you have a firewall, but as it has no policies, you might as well not have one.

2] If any policies are listed, then you do have a firewall, of sorts, which may or may not be doing what you want it to. This depends very much on the policies you have defined.

Code:

tgar@vaio:~$ sudo iptables -L
sudo: iptables -L: command not found
tgar@vaio:~$

3] The above means that iptables is not installed so you cannot have a firewall until you install and configure iptables

So, to summarise:

1] => "No"
2] => "Maybe, it depends on your iptables policies"
3] => "No"

Nobody asked you too, I certainly didn’t.

If that means I would have been better off not asking you a simple question then I agree. In point of fact I asked “anyone” and “someone”, not you specifically.

You’re a day late and a dollar short but I see you do know how to give a simple yes or no answer, or at least two out of three.

If you expect me to show appreciation after you harangue and insult me you’re dreaming. In future do us both a favor and keep your cryptic replies to yourself. Too bad there isn’t a “NO Thank You” button, I would add one to your count.
