I have Ubuntu server 12.04 installed, so I have no GUI. When I do the command ifconfig, I cannot find my internal IP address. It says inet addr: 127.0.0.1.

Here is the output of ifconfig -a:

eth0   link encap:Ethernet  HWaddr 00:06:4f:4a:66:f0
    BROADCAST MULTICAST  MTU:1500  Metric:1
    RX packets:0 errors:0 dropped:0 overruns:0 frame:0
    TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
    collisions:0 txqueuelen:1000

    RX packets:0 errors:0 dropped:0 overruns:0 frame:0

lo     Link encap:Local Loopback
    inet addr 127.0.0.1  Mask:255.0.0.0
    inet6 addr:  ::1/128 Scope:Host

    collisions:0 txqueuelen:0
    RX bytes:143896 (143.b KB)  TX bytes:143896 (143.8 KB)

here are the contents of etc/network/interfaces:

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet dhcp

If someone could edit this for me, the contents of etc/network/interfaces should be on separate lines.

The output of host askubuntu.com was:

;; connection timed out; no servers could be reached.

I set up owncloud and webmin a few months ago and was using them for a month with no problems. I think the power went off one day 2 months ago and I never turned the server back on until yesterday. I haven't done anything that would have affected the internet setup So i'm not sure why it doesn't work anymore. As far as my network topology goes, I have a pci-e network card for the pc. The ethernet line goes from the network card to a switch, and then to a modem/router from there.

I recently installed Ubuntu Server edition 13.10 (Saucy Salamander). But I have run into a bit of problem.

At the end of the installation, it asks about several extra packages whether you want them or not, like OpenSSH server and virtual machine host. Here's what I'm looking at:

Now, my problem is that I can't remember if I have checked the "virtual machine host" checkbox. How do I check if my server has the corresponding packages?

What packages come with the virtual machine host?

How do I edit an invalid sudoers file? It throws the below error and it's not allowing me to edit again to fix it.

Here is what happens:

$ sudo visudo
>>> /etc/sudoers: syntax error near line 28 <<<
sudo: parse error in /etc/sudoers near line 28
sudo: no valid sudoers sources found, quitting

I have a project with lots of hidden folders / files in it. I want to create a zip-archive of it, but in the archive shouldn't be any hidden folders / files. If files in a hidden folder are not hidden, they should also not be included.

I know that I can create a zip archive of a directory like this:

zip -r zipfile.zip directory

I also know that I can exclude files with the -x option, so I thought this might work:

zip -r zipfile.zip directory -x .*

It didn't work. All hidden directories were still in the zip-file.

I'm trying to create a zip file from a folder and I'd like to exclude the .git sub-folder from the resulting zip file.

I have gone to the parent folder of the one I want to zip (called bitvolution) and I'm doing:

zip -r bitvolution.zip bitvolution -x ".git"

But it doesn't exclude the .git sub-folder.

I've tried various combinations, -x .git*, -x \.git/*, -x .git/\*, -x \.git/\*. I've also tried using the full path for the exclude argument... but just didn't get there.
