Ubuntu Security :: Difference In The Output Of A Port Scan Using Zenmap On The Same System With UFW Turned Off And Then With It Turned On

Feb 16, 2010

This is the difference in the output of a port scan using Zenmap on the same system with UFW turned off and then with it turned on. It is obvious that UFW works.

Ubuntu Networking :: Wireless Switch Can't Be Turned On Again After Being Turned Off

Feb 2, 2010

The wireless connection works fine. The wireless switch automatically turns itself on every time I start the computer. However, after turning it off, I can't ever turn it on again unless I restart the computer. And because of this, the wireless connection is disabled until the next time I start the computer.I don't think this is a hardware problem because the switch can be turned on and off, although not in the way I expect.

I'm using ubuntu 9.10 on an Acer Aspire 4740G. The command [lspci | grep Network] shows Atheros Communications Inc. AR928X Wireless Network Adapter (PCI-Express) (rev 01). the [rfkill list] command shows (when the switch is on)

0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no

and, as expected, shows (when the switch is turned off)

0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes

I just want to be able to turn the switch on or off at any time I want as long as the computer is still on.

Debian :: Monitor / Video Output Turned Off In Wheezy?

Apr 2, 2015

Fairly new to debian and linux and general. I have an install of debian wheezy (to run LinuxCNC). I went in the graphical interface to the 'monitor' section and changed the screen resolution. I had two monitors, one labeled monitor and another (I think) Lenovo Monitor.

There was a check box in the screen monitor window that said something like, "Don't use this display." I figured it might turn off the lenovo and default to the generic monitor listed. I clicked it and my monitor turned OFF!! I tried another monitor (Dell in this case) and same thing, no video output.

I asked on the LinuxCNC forum and googled, but I just dont' seem to be able to figure out what or how to get to the solution.

I have been able to Ctrl-Alt-F1 to open a terminal. But, I can't find any the right files and found that the xrandr command 'should' work, but doesn't.

Whenever I issued the xrandr command (other than man xrandr), I get "Can't Open Display"

I did find two outputs VGA1 and LVDS1 in this file /var/log/Xorg.0.log and this coincides with what I saw in the monitor window. These are the 'output' types and if the xrandr command worked I'd issue something like : xrandr --ouptut LVDS1 --auto

I read about xorg.conf, but I could not find any xorg.conf files in the etc/X11 folder. In some of the info I found, the xorg.conf was replaced in this or a recent version of Debian by something else and confuses me.

One person had a similar issue and he got to this directory: $HOME/.e/e/config/standard" and found files such as:
"e_randr.cfg" plus "e_randr.1.cfg" thru "e_randr.9.cfg"

But, I can't get to that folder. How to turn on my monitor display?

Ubuntu Security :: Way To Make Sure That Samba Is Turned Off On Laptop?

Sep 26, 2010

I have Ubuntu 10.04 installed on my laptop which is wirelessly connected to the router. I have a PC which is Windows XP that is connected wired to the router.Now - I understand that Ubuntu is secure out of the box and so there is no need to worry about configurations. However, a past couple of updates in Ubuntu and I am seeing updates for Samba.I understand that Samba is used for file transfer between Windows and Linux.

Is Samba turned off by defult when Ubuntu is installed - despite having a WinXP computer connected to the router? Is there any way to make sure that Samba is turned off on my Ubuntu laptop?I don't want to transfer any files between my laptop and WinXP. If Samba is enabled, then a Firewall is needed to be configured (I assume), and to me that is sort of pointless with Ubuntu.For arguments sake, if Samba was enabled on my Ubuntu laptop - what would happen to my security?

Ubuntu :: NIC Not Turned Off On System Shutdown / Sort It?

Feb 26, 2010

It appears I've got some strange driver problem.. When I shut down this computer, the NIC apparently doesn't go off. The LEDs next to the ethernet socket keep blinking, so does the LED on my ethernet switch.

I don't have this problem when using XP, only Karmic. That leads me to think that there's something wrong with the network driver. My NIC is on-board, the ASUS M3A32-MVP. According to System Info this is the Marvell 88E8056 PCI-E.
It seems like ASUS doesn't have the drivers on their website (anymore), because their website search returns empty handed. Also the motherboard product page doesn't appear to know it.

Anyone have any tips / ideas? I'm just unplugging the machine before turning it off now... as it appears to be disturbing the rest of my network

Fedora Security :: The DNS Server Discloses The Remote Host Name - Can This Be Turned Off

Jun 15, 2010

We recently had a vulnerability scan done on our network and one of the vulnerabilities was that the dns server discloses the remote host name when using hostname.bind.

Is there any way that we can stop this from happening? Our name server is a Fedora 11 machine.

Security :: Turned The Router Off And On Again A Few Minutes Later Initially The Light Was Still Blinking Abnormally?

Mar 31, 2010

Not doubt this sounds alarmist, and perhaps it is... anyway, earlier tonight my mum complained that her home network connection wasn't working. After complaining about Windows and running a virus scan, I returned to my laptop, only to find my Ubuntu 10.04 was having the same problem. Then I noticed the wireless connection light (next to send and receive, which always blinks anyway) was constantly flashing, as if transmitting data, even though neither of us was connected, of course. I turned the router off and on again a few minutes later. Initially the light was still blinking abnormally, but I could now access the internet, as could mum, so I ignored it.

Later on, while the virus scan on mum's computer was running, Windows notified her she was running out of hard drive space - normally about 30GB of the 51GB HD is used on her laptop, but suddenly 50GB had been used. I also noticed my 275GB Ubuntu partition had 235GB free (although total size of files on disk was 128TB - a bug perhaps?), i.e. 40GB used, which seems pretty large for a rather fresh install and a handful of documents!Currently, everything's normal where my router's concerned (no blinking lights except for my browsing), and my Lucid partition is still showing 235GB free (strangely, mum's laptop now shows 46GB used instead of 50GB). So, what do we make of all this? Were our computers hacked for storage space?

Debian Installation :: System Booting Process Stops Halfway - Job Control Turned Off (initramfs)

Jun 4, 2015

Although I'm a linux user, I don't know much about the whole booting process myself. I normally have a friend that I can consult when things don't go the way I expected. But here's the thing: he updated my computer and went away. And of course I can't reach him and I really need it to work. And moreover, I want to be able to sole things myself.

The booting process stops halfway. The last thing it says is: can't access tty: job control turned off (initramfs) ...

Ubuntu :: Update Turned 10.04 Into A Doorstop?

Jun 6, 2010

I am kinda fed up with the a**holes who provide updates, whathaveyou. I just want to have a machine that works. And I am spending more bloody time fixing stupid problems on this system than I ever did in 20 years of using Windows. Yeah, go ahead and say that I flame. I sure as hell do when I'm mad as hell with those that purport to say that Ubuntu is for everyone.

So here is the problem I allowed an auto update to go ahead on my mums's machine (952 files of it, and received this error on reboot: There is a problem with the configuration server (/usr/lib/libgconf2-4/gconf-sanity-check-2 exited with status 256) There was also a fatal error an the mail notification module and also a gnome power management fault (can't remember the exact wording). This caused the system to fail to boot into any operational mode.

I have tried all sorts of things like pressing the SHIFT key to access the menu for previous installs (didn't work either), trying to edit the /temp folder permissions using 1777 chmod (the person failed to say though HOW to do that, as do most posts that also FAIL to tell the exact steps of doing something) which I could not do even when I got to the folder using a 10.04 boot CD as it said 'You do not have permission to change these values'. Really stupid to be locked out of a machine that no one else but my mum and me use at home. (Don't you people get that this is just STUPIDITY or plain old ARROGANCE on the part of the developers/programmers to treat us like dumbasses?). We should have the option to lock ourselves out of our own machines in the setup screen.

Anyway, can anyone see themselves getting past my angry post and actually providing some pointers? And another reason for the anger is that I DO NOT HAVE TIME FOR THIS sort of stuff to be happening all the time. I have just come out of installing Hplip-3.10.5-1 (which was NOT available as a bona fide upgrade so had to get it direct from Debian) to get an HP 3310 printer going which took two days or more. Before that it was trying to get a Canon MP130 to work, and the woes go on. Been thinking of ditching this Ubuntu but have emails etc on it that would take just too much work to get off/backup and start from scratch.

Ubuntu :: No Sound With ACPI Turned Off

Jul 8, 2011

I am running Ubuntu 8.04 (it's discontinued, I know) in an ASUS laptop. I'd had to turn ACPI off, otherwise, it would not start. I could update the BIOS, to correct this problem, but on this laptop that's not doable. Without ACPI, sound is turned off too (which is a pity). If I update to the latest Ubuntu, will this problem persist?

Ubuntu Multimedia :: Start Pulseaudio With Gdm Turned Off?

Dec 3, 2010

I'm having trouble getting pulseaudio to start without gdm/X11.

Briefly, I have a Via C7VCM mini itx system running Ubuntu 9.04
32 bit desktop that I want to run as a timed audio recorder for
a public radio station. The machine's limited in memory and
can't handle more recent installations of Ubuntu, 9.04's sufficient
for my needs.

I'm porting some old code that worked
under Red Hat 7.3. I want the ability to run X11, but normally
gdm/X11 will be disabled. The audio commands I need are aumix,
arecord and sox/play.

When I log in under X11, pulseaudio starts up and everything code...

Fedora :: Desktop Effects Turned Off?

Nov 20, 2010

After I updated to KDE 4.5.3 in Fedora 13 I've had 2 things stop starting up when I boot up. They were working fine before the KDE update.

The first is desktop effects. I turn it on, but once I reboot then desktop effects are disabled again. When I turn them on I get a KWin message that it has been turned off by another application. How can I find out which application that is and why?

The second is Yakuake, which I want to start automatically when I boot up. I don't see where I can set it up to start automatically (and I don't remember how I did it before, or if it was automatic when I installed it).

UPDATE: I just found the autostart configuration and added Yakuake. It worked, now it runs whenever I start.

Software :: Turned Off By Itself - Suspect Over Heating?

Aug 27, 2010

I have an office workstatation that I installed with linux and ran a 8-core job. It is expected that the job to finish in 6 days but then it stopped after 2 days. The reason is that when I came to office this morning the workstation is completely turned off for some reason. Since the air-conditioner is turned off in the office overnight, I suspect the temperature is too high for the cpu. Is there a script to output the temperature to a file periodically so that I can pinpoint the exact cause of the shutdown ?

Ubuntu :: Xubuntu Scrambled Screen After Compositing Turned On

Apr 28, 2010

I turned on screen compositing in xubuntu 9.1 and that scrambled the screen and now I can't read the screen. How do I undo that change? If I alt-ctr-F2 that goes to the command line. Then restartx goes back to the scrambled screen. Why does xubuntu recovery mode not offer any option to redo the video. Sorry, I assumed Xubuntu would ask for a confirmation like 'click yes if you can still see the screen' before allowing a change that can toast the system.

Also I tried:

metacity --replace returns Window manager error: Unable to open X display

xfwm4 --replace returns (xfwm4:145: Gtk-WARNING **: cannot open display
