Ubuntu 24.04.4

installing VMwareWorkstation 17.6.4 - dialog appears:

... several modules must be compiled and loaded into the running kernel

But this stops, because ...

The kernel was built by: x86_64-linux-gnu-gcc-13 (Ubuntu 13.3.0-6ubuntu2~24.04) 13.3.0
You are using: gcc (Ubuntu 13.3.0-6ubuntu2~24.04.1) 13.3.0

How do I insert

x86_64-linux-gnu-gcc-13 (Ubuntu 13.3.0-6ubuntu2~24.04) 13.3.0

into my 24.04.4,

in order to compile the 2 modules vmmon and vmnet and load them into the running kernel?

I have a newly built computer, the gpu is a radeon 9070xt and the motherboard is an msi x870e-p wifi (bios is up to date). I am getting display from the gpu (hdmi is plugged into gpu) and the gpu's fans turn on when the computer is started but turn off as soon as the ubuntu log in screen appears. I dont really know what I am doing as far as terminal commands go, and for the most part I dont know what the any of the output information means, but the commands that Ive found from websearching all seem to show that the 9070xt is being recognized by the os. Further, I tried a couple diagnostic programs like the linux hardware probe and they all show that "its working". however the gpu is not visible to programs like Blender.

Ive been trying to figure this out for weeks but everything that I am finding says that ubuntu already has the drivers I need so I have no idea what Im supposed to do, Im hoping that there's someone out there with the patience to walk me through this.

I am typing this because i do not want to make a mistake during install, is the LUKS encryption worth it? I found a question where somebody wanted to enable LUKS post-install and turned out to need to reinstall ubuntu. What are pros and cons of LUKS? And can you disable it post-install? (The version i want to install is 24.04 LTS)

Edit: Editing this so it gets re-opened. I am going to be mostly using my laptop in house, but im very worried about malware, even if linux barely gets any. (windows habit)

I'm going to have a headless ubuntu 24.04 system which I need to set up a console on. Is it possible to somehow use a different laptop system (probably MS win 11) as a console by connecting their hdmi (or usb) ports? Its network address will probably be obtained via an isp's dhcp, so probably not fixed. The user will need high-res graphics.

I have created a bootable pendrive with Ubuntu 26.04 Daily build ISO.
Downloaded from here: https://cdimage.ubuntu.com/daily-live/current/
I have successfully booted Ubuntu system. I am even writing this post form my booted live pendrive.
Now I want to install the system.
I have desktop icon "Install Ubuntu 26.04 LTS" which when double clicked does not work. Nothing shows up.
I have also on the left side panel icon "Install RELEASE" which also doesn't work when clicked.

I have launched terminal and wanted to manually start installation process.

sudo snap run ubuntu-desktop-bootstrap

bin/bash: /snap/ubuntu-desktop-bootstrap/515/usr/lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.42' not found (required by /usr/lib/x86_64-linux-gnu/libtinfo.so.6)

When i check the glibc version, I seem to have correct one.

Has anyone tried to install the newest preliminary release?

I have an issue I am working with R, and using chrome, but only like 7 tabs, not more and got every couple of minute this error - Out of memory chrome - kiiling all processes number of processes in black screen..

And then it just logged out from my ubuntu..

I am not programmist, just tring to analyse some data not sure what this is and how to fix it.

I have found a lot of the same issues but not sure where to start and it's a scary thing to install or update something because I have a bad experience when this lead me to lose ubuntu and data on my laptop.

My ubuntu is pretty old - ubuntu 20.04

Google Chrome 130.0.6723.91

I want to install the Canon imageRUNNER 2425 driver in my system. I tried other options from YouTube and Ubuntu, but I could not get the printer driver installed successfully.

Many consumer network printers offer the possibility to share the inserted SD Card in a network. While the more advanced (business) printers allow to configure a remote directory where scans are written to, these consumer (or older?) devices often only allow sharing "their" SD card. I tried this on for different printers. For example a HP CM1312nfi and a Epson BX635FWD. Both devices offer sharing their SD card. For both Devices, a Windows client can directly access the share, here for example for the HP device: The windows client automatically detects a network share and I can read/write it:

However, if I try to access these shares from Ubuntu (Kubuntu 25.10 to be precise) the System alsways asks for credentials where there are none. If I use the samba integration into KDE/Dolphin, I can see the share, but it asks for username/password if I open it. If I use fstab to mount this with the following configuration:

//192.168.178.31/memory_card /media/lghp cifs user,noauto,vers=1.0,rw 2

It asks me for the password of my ubuntu user

If I try something like:

//192.168.178.31/memory_card /media/lghp cifs user,username="Guest",password="",sec=ntlmv2,nounix,vers=1.0,rw 2

It responds "Permission denied". When omitting the password option, it again asks for one. Are there any universal default credentials which are used by the windows machine? The HP device even states that it uses CIFS for sharing.

I am trying to access data ont old RAID drive (1 of 2 mirrored). Recognized by Ubuntu as /dev/sda with 4 partitions.

I am using mdadm package. What I did:

sudo mdadm --assemble --run /dev/md127 /dev/sda4
mdadm: /dev/md127 has been started with 1 drive (out of 2).

then

sudo mdadm -D /dev/md127
/dev/md127:

and

sudo mdadm -E /dev/md127
mdadm: No md superblock detected on /dev/md127.

next was

sudo mount -o ro /dev/md127 /mnt/disk2
mount: /mnt/disk2: wrong fs type, bad option, bad superblock on /dev/md127, missing codepage or helper program, or other error.

and there I am stuck. Tried to specify FS as ext2, ext3, ext4 - didn't work. Checked

sudo mdadm --examine --scan
ARRAY /dev/md127 UUID=84f20cfc:0d2045e1:e368bf24:bd0fce41

and nothing changes. What am I doing wrong????

P.S. RAID was built automaticaly in WD NAS without manual settings. It was 1 drive NAS so I don't get why it shows as RAID.

kvm_amd CPU x isn't AMD or Hygon?

This text appear early in the boot sequence.

Now this is not really causing any trouble, RIGHT NOW.
But I consider all similar messages to be a potential hazard to the stability of my machine.
Therefore I quite fiercely hunt them down, and "swat them out".
The more of these unwanted messages you have the greater potential for strange interference and malfunction.

These are apparently about virtualbox:

... but I have this on intel-based hardware,
an oldish i7-9750H-based Asus G731 laptop, with embedded GTX 1660 Ti.

I have:

in /etc/default/grub

No go.

$ sudo -i

Reboot... I still get a black screen with these boot messages:

Does anyone have any more ideas on how to actually get rid of this?

I’m preparing several Raspberry Pis that will all run Ubuntu Server. Since each device needs the same applications and initial configuration, I want to create a preconfigured image that I can flash onto any SD card. The only thing that should differ between devices is the Wi‑Fi configuration.

I need to be able to change the Wi‑Fi settings offline, while the SD card is mounted on another Linux system, before booting the Raspberry Pi. However, I can’t find any documentation on how to modify the Wi‑Fi configuration via Netplan without knowing the exact WLAN interface name or being able to run commands on the Pi itself.

It must be possible, though — for example, the Raspberry Pi Imager allows you to set Wi‑Fi credentials through its UI, and the system connects successfully on first boot.

Delete / empty trash “Bin” in file system, can you do it safely ? Bin 2690 items / X11 has black arrow ? I have never seen it till updating to 20.04 ? Help very much appreciated. Les

A recent auto-upgrade from 6.14.0-37 to 6.17.0-14 yields a kernel panic at boot: Unable to mount root fs Unknown Block (0,0)

To get the machine up I have to select 6.14.0-37 from the GRUB boot menu. I can no longer do a normal boot/reboot because GRUB auto boots the newest (bad) kernel. I want to remove 6.17.0-14 from the GRUB menu.

All the help articles I've found instruct how to remove old kernel versions. How do I remove the NEWEST kernel version and retain the oldest in GRUB?

DKMS issue relates to building the VirtulBox 7.0.16 kernel module

I recently installed 24.04.04 on my Lenovo Slim 7 14ILL10 (dual booting with Windows). Audio from my speakers and headphone jack did not work at all. I followed the below guide and installed Cirrus drivers. https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/2137115. My speakers now work.

Unfortunately my headphone jack still does not work. Interestingly, testing the headphone output through the Settings app shows sound packets "playing" through my headphones, but no noise at all.

Below is some information that may be helpful.

Edit - I included arecord -L. Hopefully this helps.

Edit 2 - I booted into Fedora. Both the speakers and headphone jack work without issue. Makes me think this is a Ubuntu or Debian specific issue.

Subsystem: Lenovo Device [17aa:3838].

This appears to be a recurring problem with no definitive answer: each time it comes up, a previous solution fails to work and a new answer is needed. I've lost track of how many questions and 'answers' I've read on this.

There must be many thousands of people who rely upon Virtualbox to run other Linux, and especially Windows, on Linux. And many will be on Ubuntu. So I don't understand why there isn't already a fix. I don't even know which update caused it. All of a sudden, VB can't start a virtual machine.

Would subscribing to Ubuntu Pro help?

Perhaps I got a 'phased' update, so most of the rest of you are oblivious of the problem?

NB, I've checked the BIOS: secure boot is DISABLED.

Below is some of what I've tried.

Edit 1, Edit 2, etc, are my responses to @heynnema's heroic efforts to find the solution for me. Our exchange (including help from @nobody) was moved by a moderator from Comments to Chat.

So, first try what it says in the error message:

I forgot to capture this before attempting to reinstall VB --- it's gone.

Tried to install a later version of VB direct from Oracle: failed.
Now I get: "Failed to acquire the VirtualBox COM object. The application will now terminate."

Yes, I know, I should have taken a more systematic approach. But it's difficult to write this on the machine you're trying to fix. Especially as some 'answers' have such enticing 'solutions'...

$ ll /usr/bin | grep gcc
lrwxrwxrwx  1 root root   23 Sep  4  2024 gcc-13 -> x86_64-linux-gnu-gcc-13*

So it would appear the warning about the compiler is a red herring.

Synaptic used to install virtualbox 7.0.16-dfsg-2ubuntu1.1
Synaptic also chose and installed virtualbox-dkms and virtualbox-qt

Virtualbox will run, but I'm back to the original problem.

Edit 6

Synaptic search for "linux-headers-generic":
Looks like the 6.8 headers are still installed.

Uninstall?

From HWE kernels in Ubuntu docs: "HWE (Hardware Enablement) kernels are only enabled on Ubuntu long-term support (LTS) releases...By default, Ubuntu Desktop installations of 24.04 default to tracking the HWE stack.".

sudo apt purge virtualbox-7.2 Appears to remove 7.0, then says, "Package virtualbox-7.2 which provides virtualbox is not installed" ! Did I use the wrong command?

@heynnema: "Install virtualbox-source and virtualbox-modules using Synaptic"

Synaptic shows virtualbox-source but no virtualbox-modules.

Install via Synaptic of virtualbox-source:

E: virtualbox-dkms: installed virtualbox-dkms package post-installation script subprocess returned error exit status 10

But Synaptic does show virtualbox-source as installed.

In the description of virtualbox-source: "The source is placed under /usr/src, and after decompression it can be built to produce a virtualbox-modules-KVERS providing "virtualbox-modules" package." So I shall proceed with the source install...

After install, there is /usr/src/virtualbox.tar.bz2.

Extracting that creates /usr/src/modules/virtualbox/, which contains:

Currently, I can copy, edit, move, etc. files using terminal so drive itself and permissions seem no problem, edit using nano, etc., but nautilus seems to just want to crash (like it's corrupt) so want to reinstall, not repair, it.

from terminal:

Desktop$ nautilus

Shouldn't that be Gsk.NglRenderer, not GskNglRenderer?

OK, Daniel T, I ran dpkg -V, but no /bin lines at all:

In lieu of using termnal on the desktop, would using the RECOVERY tool from grub and dropping into root be better way to uninstall, then reboot and again to the tool to root, to reinstall nautilus?

I can run Firefox, browse away, play things, etc., and all is fine until I try to attach a file to an email which tries to bring up a nautilus type window, or try to download/save a file which also tries to bring up a nautilus type window, then it'll try but ends up crashing Firefox during the attempt. I assume a piece of nautilus is what the browser uses - same with using something like LibreOffice - try to open a file which tries to bring up the window and that does similarly...

using "LIBGL_ALWAYS_SOFTWARE=1 nautilus", I noticed I can rename a file, but try to copy it, and the freeze/blink off-on/crash happen as the window pops up (with read only message at its bottom) for where to copy it to...

Maybe I have not found a way to get a good scan in Ubuntu. IMHO, a good scan file is high resolution and small. For the same resolution, smaller is better.

I scan documents almost exclusively. For example, nowadays I am scanning hard copy tax documents that arrive in the mail, as my accountant expects everything to be uploaded.

I have tried xsane, scanlite and scanpage, but the files are typically ginormous (bigger than a MB). Using Windows Fax and Scan in Windows 7, I set the resolution to 300 dpi and scanned an Ubuntu printer test printout. I get a nice looking image tiff that weighs in at 66 Kb.

You can see for yourself, download what I got here, filename:

Windows_Fax_n_Scan_ubuntu_print_test_2026-02-07.tiff

You can try it! Print a test page in your system settings, printers. Then scan it and compare what you got with what I got from Windows 7.

(I have not tried later Windows versions. I need Windows 7 for one application. I do not use Windows 7 for email or surfing.)

As suggested by Daniel T, in Ubuntu, I tried simple-scan on the same printer test printout. I set the resolution to 300 dpi and compression at max. I got a 143 Kb pdf (more than double the size of the Windows 7 scan). To my eye, the print is dark gray, not as black as in the tiff. You can download what I got here, filename:

simple-scan_text_300dpi_max_compress_2026-02-07.pdf

Again, if you like, you can try it and see for yourself.

Until I find a good way to scan in Ubuntu, I will be dual booting into Windows 7 when I need to scan. Is there a way to scan in Ubuntu that I have not discovered? If there is no way to get an equally small and crisp document scan in Ubuntu, I am hoping to get the attention of the developers of an Ubuntu scan app, hence challenging them to scan as good as Windows 7.

I am having a recurring problem (it sometimes fixes itself after a few days) that is quite annoying: my sound starts crackling (it seems the crackling comes from the jack area somehow), then some time later stops. When checking the settings, I can see the dreaded "dummy output". I tried quite a few things I saw online (and perhaps misconfigured some things in the way as I do not understand everything) to no avail.

Here is a bunch of information that I saw were shared in several threads. I have a dual boot Ubuntu - Windows.

Here are some screenshots:

• Pavucontrol shows dummy output.

  

• Alsamixer shows 2 graphic cards, I think.

  

• The Nvidia doesn't show much (four S/PDIF with no vertical bars).

  

• The Intel shows a vertical bar for PCM (and four S/PDIF with no vertical bars).

  

When I open Text Editor, it will open the last file. I wonder if I can modify the setting to disable it. If so, how can I do.

My System is Ubuntu 24.04.1 LTS Desktop. I don't know which version the text-editor is. But I just update it yesterday.

I am trying to get a GPU system load monitor to work in xfce4 panel. Is there any way to configure the current CPU system load monitor to reflect GPU usage? I know we can run a script in genmon generic monitor but I don't have the skills necessary to create the script.

I have an AMD GPU and currently use gpu-mon --gui for monitoring but would like to have something similar to the CPU monitor in the panel, preferably for GPU load and vram mem load.

Thanks

I want to make a launcher icon on the dock for VSCode under Ubuntu 20.04. I called it code.desktop and put it in .local/share/applications, then pinned it to the dock. However, when I click on it, I get two icons:

The desktop file looks like this:

[Desktop Entry]
X-SnapInstanceName=code
Name=Visual Studio Code
Comment=Code Editing. Redefined.
NoDisplay=false
GenericName=Text Editor
Exec=/snap/bin/code
Icon=/snap/code/49/meta/gui/com.visualstudio.code.png
Type=Application
StartupNotify=false
StartupWMClass=code
Categories=Utility;TextEditor;Development;IDE;
MimeType=text/plain;inode/directory;application/x-code-workspace;
Keywords=vscode;

What gives? I tried the instructions here but they seem to be either obsolete or not applicable to VS Code somehow. wmprop gives me "code", "Code" for the WMClass, and as you can see I've already set that as the StartupWMClass (and the filename of the desktop file, as someone else recommended at that link).

I'm struggling to connect my KVM virtual machine to the local network.

$ brctl show br0
bridge name    bridge id            STP enabled    interfaces
br0            8000.4c5262097e59    yes            enp0s31f6
                                                   vnet0

enp0s31f6 is the hosts' ethenet card and vnet0 that of the KVM guest.

On the host, I have full network connectivity. No problems.

On the vm, I have no network connectivity at all:

$ping 8.8.8.8
connect: Network is unreachable

So I'm trying to figure out what is worng. Already here, I'm puzzled because I thought that a bridge is the equivalent of a hardware switch and if this is so, how can one device plugged into the switch reach the network but not the other?

Let's look at their IP addresses:

$ ip a show enp0s31f6
2: enp0s31f6: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel master br0 state UP group default qlen 1000
    link/ether 4c:52:62:09:7e:59 brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.4/24 brd 192.168.1.255 scope global enp0s31f6
       valid_lft forever preferred_lft forever
$ ip a show vnet0
26: vnet0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel master br0 state UNKNOWN group default qlen 1000
    link/ether fe:54:00:f0:0e:f8 brd ff:ff:ff:ff:ff:ff
    inet6 fe80::fc54:ff:fef0:ef8/64 scope link 
       valid_lft forever preferred_lft forever

So, the host has an IP 192.168.1.4 but the vm doesn't (except for an IPv6, no idea why).

The host received it's IP from the DHCP server on the LAN:

So let's try to get one for the vm too:

It doesn't get one. :-(

So maybe the bridge is broken and the host still gets an IP because it is physically connected to the LAN? No, because the bridge itself does seem to talk the DHCP server too:

How do I continue from here?

(Feels like I have tried an checked just about everything, but I'm sparing you the information about that here as I'm now trying to systematically identify where I'm going wrong in the above steps.)

I am quite new to linux and have recently installed Ubunutu 18.04 LTS.

I am trying to install NASA GMAT (available at https://sourceforge.net/projects/gmat/). After downloading .tar.gz I extracted the archive and found a README file. The command line version of GMAT found in /bin of the file works perfectly fine.

However, when I try to run "./GMAT_Beta" I get the following error:

./GMAT_Beta./GMAT_Beta: error while loading shared libraries: libpng15.so.15: cannot open shared object file: No such file or directory

Now I have checked via Synaptics Package Manger and using apt command that I have libpng16-16 - installed version "1.6.34-1ubuntu.18.04.2".

I want to install libpng15 for GMAT to function. Can someone please guide me: 1. Where and how to install libpng15 from? 2. Will I have to remove the already installed version or can they co-exist together?

I am running Ubuntu 16.04

NetworkManager --version

returns 1.2.6

I am wanting to update to the lastest stable version (1.14.4) from here.

The install documentation says "the shell command './configure && make && make install' should configure, build, and install this package."

After much trial and error I managed to get ./configure to complete with out reporting any errors by installing the following packages:

apt-get install gtk-doc-tools libglib2.0-dev libudev-dev uuid-dev libnss3-dev ppp-dev libjansson-dev libcurl4-nss-dev libndp-dev libreadline-dev intltool

However when I run make I get:

mike@Ubuntu16:~/Downloads/NetworkManager-1.14.4$ make
make  all-recursive

Any help with this would be greatly appreciated.

I started my laptop Toshiba Satellite L755 as usual this morning for work, but suddenly I got into a login loop. After reading some tips here, I tried the shell login mode. After logging in using shell mode successfully, I restarted my laptop using power button forcefully. Because after logging in I couldn't do anything due to my screen keep flipping and change back to boot screen. I noticed there is a Nvidia driver loading line at the bottom. While the boot load screen like 3 seconds, it keeps logging in and same screen for infinite amount of time. After the forceful power button push, I started the laptop again. Now it logs in normally, but I think Ubuntu 18.04 is broken. I have attached a screenshot.

As you can see that, all the icons are big and there is no sidebar. Also, there is no application menu button anywhere on the screen. The theme changed to white color but it was total dark theme before. My system menu also changed. There were so many options available there.

I want to revert back to my old Ubuntu system. This would be a great loss if any files goes missing from my system folders like document or download. As, I cannot see some of my folders created inside the downloads folder.

I tried the Resetter also. I included one screenshot of my terminal with error messages. I need a solid repair solution.

Running Kubuntu 17.10.

I installed printer-driver-cups-pdf.

When I print from any application (native ones like Kate or others like Firefox), there is a default 'Print to file' printer and a 'PDF' printer like this:

I can select 'Print to file' printer and choose the filename and folder where to save the file.

But when I choose 'PDF' printer, it asks for nothing. It just shows a window as if it is sending pages to a printer. Then the window disappears. I am not able to get a screenshot of this window as it disappears pretty fast.

But where are the files? They are not in ~, ~/Downloads, /tmp or ~/Documents

1.Do you recomend using sudo apt-get upgrade command before installing Synaptic through terminal?

2.(in the future): Before uninstalling an old module version which was ACTIVE on this kernel, should i manually set it to inactive ? Or ubuntu does this by default with an OK exit in all cases?

3.please observe the 2 errors:

a. Error! Bad return status for module build on kernel
b. error processing package oem

4.whats worse: being a 3rd party, could not report the ,,serious problem”

below, I will post the output of my terminal. Is this normal ?

I'm trying to get an OpenStack Nova compute node running within a container to boot a server in a nested container.

Everything works fine until I ask Nova in the controller to boot the server. During the server boot process in the compute container, libvirt uses qemu-nbd to export the qcow2 disk image downloaded from OpenStack Glance as a previous step to launching the nested container. With the default lxc configuration qemu-nbd fails.

I've worked out the lxc.conf file to allow using qemu-nbd from within the container, but I must be missing something because even if the container activates the node /dev/nbd0 I can't see the /dev/nbd0p1 entry corresponding to the partition in the qcow2 disk image.

Here's the lxc.conf file for my Nova container:

# Template used to create this container: /usr/share/lxc/templates/lxc-download
# Parameters passed to the template: -d ubuntu -r trusty -a i386

# Added so certain functions (iptables, nova-compute, ...) work
lxc.mount.entry = /lib/modules/3.13.0-43-generic     /var/lib/lxc/compute/rootfs/lib/modules/3.13.0-43-generic none ro,bind 0 0

# Added so the compute node can run LXC VMs
lxc.mount.auto = cgroup

# Allow the container to mknod (needed by qemu-nbd...)
lxc.cgroup.devices.allow = c *:* m
lxc.cgroup.devices.allow = b *:* m

# Allow the container to use the host's nbd devices
lxc.cgroup.devices.allow = b 43:* rwm # Every nbd device in the host

It can be verified easily on the command line. Assuming we have the qcow disk image in /root/cirros-0.3.3-i386-disk.img:

root@compute:~# qemu-nbd -c /dev/nbd0 cirros-0.3.3-i386-disk.img -f qcow2
root@compute:~# ls -d /sys/class/block/nbd0p1
/sys/class/block/nbd0  /sys/class/block/ndb0p1
root@compute:~# ls /dev/nbd0*
/dev/nbd0

It seems the block device exists in the kernel, but the /dev/nbd0p1 device node has not been created. Anyone knows what am I missing in my container configuration?

P.S. I know OpenStack Nova by default doesn't work with container VMs, there are some changes I need to do in Nova code; but I need to overcome this hurdle first

I've just installed apache2 on my box, along with php5.

I can navigate to "localhost" and it works. But I can't access this webserver from another machine... or even locally using the IP address. Other posts such as Apache (and other services) work on localhost, but not IP address suggest firewall settings and also checking to make sure I'm listening not just on localhost but *80.

This is what I have in ports.conf:

me@mydev:/etc/apache2$ cat ports.conf 
# If you just change the port or add more ports here, you will likely also
# have to change the VirtualHost statement in
# /etc/apache2/sites-enabled/000-default.conf

Listen 80

<IfModule ssl_module>   Listen 443 </IfModule>

<IfModule mod_gnutls.c>     Listen 443 </IfModule>

# vim: syntax=apache ts=4 sw=4 sts=4 sr noet 

The default firewall doesn't seem to be enabled:

me@mydev:/etc/apache2$ sudo ufw status
[sudo] password for me: 
Status: inactive
me@mydev:/etc/apache2$ 

Just not sure what else I should check. Thanks.

EDIT 1

Results from IP tables query:

me@mydev:/etc/apache2$ sudo iptables -L
[sudo] password for me: 
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
me@mydev:/etc/apache2$

And I am able to successfully ping the box from different machines.
