Internet slow in Ubuntu 10.04---Firewall Issue?


I am currently using Release Ubuntu 10.04 (lucid)
Kernel Linux 2.6.32.24-generic
Gnome 2.30.2

My question is: How can I tell if my fire wall is on? The reason I asked this is because My internet is running really slow and choppy.....I have 3.5MBPS but I feel like its Dial-up. I have a New Lap top with 1gig-mem,1.6 processor and 320gig Hd. All your help is very APPRECIATED.

If you type `iptables -L` using sudo or as root, and it shows a bunch of chains & tables filled with stuff, then your iptables firewall is active (assuming you use iptables, which you probably are, but if not, please tell us what sort of firewall it is).

One thing I'd check is whether or not you have IPv6 enabled in your browser and/or in your kernel, and if so, then disable it if you are not needing it.

If I may, I'd also recommend a more suitable title for your thread, something like "Firewall problem? Internet speed slow in Ubuntu 10.04.", as your current title is not really indicative of the issue - I thought it had to do with the game

Assuming that Ubuntu has a firewall, there will be a control panel somewhere in the menus. Regardless, a firewall will block certain sites or domains, but I don't think it will cause a general slowdown.

Try a speed test using something like Speakeasy: http://www.speakeasy.net/speedtest/

What is your connection?---eg DSL, cable, etc.?

Does the slowdown occur at a specific time of day?

The issue isn't whether I like the title or not; the issue is how much exposure your thread/question will get from LQ members reading the title. Someone reading a title "Need for Speed" who can help with your issue, may not bother reading the thread because they think the thread is going to be about the video game, the result being that someone who may have been able to help you, now will not.

I made the suggestion in your interest; it's entirely up to you to leave it or change it.

pappabear@pappabear-laptop:~$ iptables -L
FATAL: Error inserting ip_tables (/lib/modules/2.6.32-24-generic/kernel/net/ipv4/netfilter/ip_tables.ko): Operation not permitted
iptables v1.4.4: can't initialize iptables table `filter': Permission denied (you must be root)
Perhaps iptables or your kernel needs to be upgraded.

That's not getting you off to a good start here!!

The advice from GrapefruiTgirl was to run as root or use "sudo" (In Ubuntu, it's the latter.)

You did not answer my questions/suggestions.

I'll change the title....

Having the title that actually reflects the problem will result in more people looking at the thread and helping.

Doesn't ubuntu come with Firestarter installed?

Chances are what you are seeing can be fixed by disabling ipv6.

You know............... I wasn't trying to get a bunch of DRAMA from this thread. I'm Sorry if people got upset. I just wanted help from other Linux users. I didn't reply to pixellany's post because the answer was in my original thread. I am an avid user of Debian Linux non-Gui and DSL but have not messed with Ubuntu's firewall until now. Thanks for all your help this post is done with!


No hard feelings.

No hard feelings at all -- what would be life without a little DRAMA now and then

You mention the answer is in your "original thread" - perhaps you could provide a link here to that thread, and if this one is now solved, mark it [SOLVED] using the Thread Tools link near the top of the page.

Happy internetting!

No hard feelings.
As suggested by GrapefruiTgirl, you should not assume that someone has read you other threads---you need to provide a link.

Common courtesy dictates responding to people's questions even if you think they somehow should have know the answer.

Ditto "no hard feelings"---Good Luck to you.
