Ubuntu :: How To Turn Firewall
Jul 19, 2009
How to turn OFF firewall. But how and ever, I noticed unlike the other distros ubuntu has a specific driver for my graphic card PNY nvidia GeForce under gnome system administration.
As soon as I selected that I lost my network connection. I did some trouble shooting and am concluding it has to be software setting to do with ubuntu more than likely some sort of firewall.
I was not able to ping anything. I could not even get my router's browser.
The very act of setting up the graphic must have thrown off the router settings.
I booted into the dual boot windows setup on the same system and WAS able to log into router ( no firewall installed ). True to enough, the router password and username were taken off. Now I can get a network with windows but the ubuntu that is on my hard drive still wont connect.
I can also use ubuntu live dvd to log in to network.
I have checked gnomes system authorizations but have not found anything helpful.
I have setup a static ip in /etc/network/interfaces and name server in /etc/resolv.conf
If this was windows I would reset tcp/ip but don't how this is done in Linux.

I suspect this is an initial configuration bug. All firewall logs seem to be going to all
three files. That causes a lot of clutter in the log files, and makes it difficult to see whether there are any serious problems being logged.

I am learning to setup firewall in my home for that i have selected four system(sys1,sys2....sys4) for testing .I have configured sys2 to act as a firewall with two NIC. sys3 and sys4 are inside the firewall . sys1 is not connected to firewall for testing purpose.
the IP assignments are follows :
sys1 : ( fedora, not connected to firewall i am thinking, But i am not sure )
IP : 192.168.2.1 ,
gateway : blank
dns1 : blank
dns2 : blank
sys2 firewall ,IPTABLES )
code....
what happened is that sys1(not connected to firewall) can ssh to sys4(connected,inside firewall),since the rules are written not to ssh form sys1 to sys4..
then I came to know whatever the request I give, It directly goes as sys1 --> sys4. Not as sys1-----> sys2(firewall)---> sys4 .and the firewall is not filtering and processing anything for both inbound and outbound (i think it's my mistake some where). the requests are directly going inside without firewall.

And when it ask me about plugin I give the path to it. (the 3.9.2 version of the plugin, because Ubuntu 9.04 has the 3.9.2 version of hplip)

I'm trying to build firewall on Debian with 'Firewall Builder'. But it won't let me compile and run unless one interface is set as management. There are two interfaces on my computer: 'eth0' and 'lo'
I don't want to be able to configure firewall remotely, so could I use 'lo' as 'management interface'?

On Windows I use software called SpeedFan to turn off a fan that does a whole lot of noise but has no effect on system temperature.
How do I go about turning it off on Ubuntu (Lucid Lynx)? Wine does not support this program.

My ubuntu 10.04 doesnt want to turn off my PC (desktop) when I click turn off in the menu. I get no message, and I get no signs of higher system activity. This happens with turning off, rebooting, logging off user. However I can do it from terminal with admin rights.

What is the best (by best I mean most secure) firewall. I have had this urge since I went to a site which said it had a gnomenu icon, however google chrome said something which I didn't read i just killed chrome very quickly however it had a big red X and a red background so I guess it couldn't be good.

With 9.04UNR it was possible to turn off the touchpad in the mouse control but it doesn't appear to be there in in 10.04. Is that still possible with 10.04? If so, where do I look for it?

When I mistype a name of an executable program in terminal, ubuntu tries to search for similar programs in packages and then suggests names. This takes time, slowing down work and entirely useless for me. How to turn this feature off?
I personally can't even find a reason for implementing this feature and rather making it turned on by default. If someone needs a tool, he/she can search through packages.

my laptop is an Acer5920G with an NVIDIA GeForce8600m GS video card. I am running Lucid Lynx on it. My problem is that I don't know how to turn the screen backlighting on - my screen seems to be on energy saving mode, i.e. quite dark. I somehow managed to turn the backlight back on the other day, but I have no idea how - and it went back to non-backlit mode a few days later. What should I do?

Wi-fi adapter is switched-off only in Windows or BIOS, and there is nothing built-in NetworkManager not able to do, put the different eee applets - not a solution either. It is worth Netbook Remix 10.10, asus eee 1001ha. All other shortcuts work fine (sorry for my english)

When I boot it takes about 5 seconds for the firewire device (fw0) to load. I don't use firewire and I would like to disable it to help improve my boot time. My BIOS doesn't have an option to turn it off. Is there a way I can turn it off in Ubuntu?

I just installed ubuntu studio and it looks better than ever. I have an ice1712 soundcard and I have NEVER had it work on ANY linux distribution that used pulseaudio (I'm guessing that this problem has been around for at least two years) so I proceeded with my usual way of fixing things which is to just get rid of pulseaudio. Well it worked like a charm, uninstall pulseaudio, reboot and there's my sound. Here is my problem, I went to >system >preferences >sound to turn of the system sounds. I get a message, "waiting for sound system to respond" Does anyone know how I can make these sounds go away. I'm happy to try anything.

The title says it all: my computer won't resume my current session after I suspend it. Nothing works, and I have to turn off the computer and start it again in order to log in.
P.S.: I'm using the latest version of ubuntu (11.04)
P.S. II: I turn the pc off by hold the power buton for 3 - 5 secs.
P.D. III: If I tap the power button, I can hear the pc start working, but the desktop stays blanked out.
