I just made a clean install of Fedora 20 as a VM in VirtualBox. I set up the VM to use NAT as part of the network configuration in VirtualBox.  At first I could ping google.com, but could not browse using Firefox. And when I tried to execute yum update I got the following error:  Loaded plugins: langpacks, refresh-packagekit Error: Cannot retrieve metalink for repository: fedora/20/x86_64. Please verify its path and try again   Then I disabled IPv6 in the network settings, and I also disabled this option in Firefox. As a result I was able to browse using Firefox, but I still keep getting the error when doing yum update.  When I do URLGRABBER_DEBUG=1 yum check-update I get:  2013-12-20 11:33:35,612 attempt 1/10: https://mirrors.fedoraproject.org/metalink?repo=fedora-20&amp;arch=x86_64 2013-12-20 11:33:35,612 opening local file "/var/cache/yum/x86_64/20/fedora/metalink.xml.tmp" with mode wb * Adding handle: conn: 0x1c896d0 * Adding handle: send: 0 * Adding handle: recv: 0 * Curl_addHandleToPipeline: length: 1 * - Conn 9 (0x1c896d0) send_pipe: 1, recv_pipe: 0 * Could not resolve host: mirrors.fedoraproject.org * Closing connection 9 2013-12-20 11:33:45,169 exception: [Errno 14] curl#6 - "Could not resolve host: mirrors.fedoraproject.org" 2013-12-20 11:33:45,169 retrycode (14) not in list [-1, 2, 4, 5, 6, 7], re-raising Error: Cannot retrieve metalink for repository: fedora/20/x86_64.

I followed the suggestion of enabling the DNS proxy in NAT mode, but the same problem persists (I can still browse in Firefox, but yum cannot resolve the host mirrors.fedoraproject.org). Now the ifconfig commands shows this:  p2p1: flags=4163&lt;UP,BROADCAST,RUNNING,MULTICAST&gt;  mtu 1500         inet 10.0.2.15  netmask 255.255.255.0  broadcast 0.0.0.0         inet6 fe80::a00:27ff:fea4:a4c6  prefixlen 64  scopeid 0x20&lt;link&gt;         ether 08:00:27:a4:a4:c6  txqueuelen 1000  (Ethernet)         RX packets 723  bytes 695639 (679.3 KiB)         RX errors 0  dropped 0  overruns 0  frame 0         TX packets 628  bytes 77437 (75.6 KiB)         TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0         device interrupt 19  base 0xd020    An the cat /etc/resolv.conf shows this:  nameserver 10.0.2.3   And finally, I tried "Using the host's resolver as a DNS proxy in NAT mode" and the issue was finally fixed.
I am running a fresh install of Linux Mint Nadia (14). I am following the instructions on Vagrant  but have gotten stuck on the . It seems the Vagrant box cannot connect outside and so I can't install anything using either Chef or Puppet.  In the basic Vagrant resolve.conf contains nameserver 10.0.2.3. But with that set I can't ping us.archive.ubuntu.com.  If I change it to 8.8.8.8 then I can ping us.archive.ubuntu.com but it does not stay set, and after a reboot it changes back to 10.0.2.3 - so provisioning fails again.  Ideally I would like for 10.0.2.3 to work on my setup. Failing that I would like a way to permanently change resolv.conf so that I can do provisioning.

"There Is"/"There are" depends on plurality of the first list element or not? Hello [Comma?] John, I have a follow up question to this question:   My question is: when should you add a comma when starting a letter/email with     Hello John,      It was fun to see ...   I am pretty sure that a comma goes after the name, but lately I have seen several people (academics) write      Hello, John,       It was fun to see ...   with a comma after the Hello.  I am wondering when a comma there is appropriate.    I see this question  but I am wondering about the situation where you have a comma after the name also. I use this program in Windows that's one-box and searches all of my drives. By default it lists all files, everywhere, in a single list. Is there a Linux graphical utility that does this? Filling in new field in attribute table based on values of another field in ArcGIS Desktop? I have added a new field (Category) in an attribute table of a shapefile and I would like to fill it with numbers, 0 or 1, based on the numbers of another field (Calorific value) of the same attribute table.   That means that if the Calorific value is higher than 15, then I would like to fill in the corresponding cells of the (new) Category field with 1. If the Calorific value is less than 15, then the rest cells of the (new) Category field to be filled in with the number 0.   Is there a way to do this automatically rather than manually? When it comes to , I often read recommendations like "Use adb logcat to find some more details". Looking for a good way to backup all my apps including their data,  refers to adb backup and adb restore. In several places one can find ways to remotely do on an Android device with the use of , such as transferring files using adb push or adb pull, accessing the  via adb shell, and more. So ADB seems to be a good thing to have for an Android user.  But how to get this "ADB thingy" on my computer? Not being a developer, installing the entire  seems a bit overkill. Is there a more minimalistic approach available? How do you end with a single quote followed by a double quote? I have a paragraph as follows:  ``This is a quote. `Here is a quote within a quote.'''   But the formatting works out to be a double quote (") followed by a single quote (') instead of the other way around. How can I solve this problem? Setting page numbering on Word I have a word document. The first four pages are title and index. After that, the “Chapter 1” starts. I want page numbers to begin from the “Chapter 1” onwards only. The first 4 pages should not have any page number.  How do I achieve this? Understanding Bash's Read-a-File Command Substitution I am trying to understand how exactly Bash treats the following line:  $(&lt; "$FILE")   According to the Bash man page, this is equivalent to:  $(cat "$FILE")   and I can follow the line of reasoning for this second line. Bash performs variable expansion on $FILE, enters command substitution, passes the value of $FILE to cat, cat outputs the contents of $FILE to standard output, command substitution finishes by replacing the entire line with the standard output resulting from the command inside, and Bash attempts to execute it like a simple command.  However, for the first line I mentioned above, I understand it as: Bash performs variable substitution on $FILE, Bash opens $FILE for reading on standard input, somehow standard input is copied to standard output, command substitution finishes, and Bash attempts to execute the resulting standard output.  Can someone please explain to me how the contents of $FILE goes from stdin to stdout? 0 ram free on ICS It maby be weird, I want to make header and footer for every page including the first page of each chapter, how can I do this? Finite Sum $\sum\limits_{k=1}^{m-1}\frac{1}{\sin^2\frac{k\pi}{m}}$ OpenSSL remains vulnerable after update to 14.04 Most incarnations of The Hulk I've seen or read about state that he is as strong as he needs, basically meaning that there is no limit to how strong he can get.  Is there any canon regarding this? Have we seen the upper limit of the Hulk's strength? Is a Cauchy sequence - preserving (continuous) function is (uniformly) continuous? Let $(X,d)$ and $(Y,\rho)$ be metric spaces and $f:X\to Y$ be a function and suppose for any Cauchy sequence $(a_n)$ in $X$, $(f(a_n))$ is a Cauchy sequence in $Y$.  Is $f$ continuous?  Let $f$ be continuous, is it uniformly continuous? Deciphering the RSA encrypted message from three different public keys What are the ways to solve cubic equations? Cubic equations of the form $ax^3+bx^2+cx+d$ can be solved in various ways. Some are easy to easy to factor in a pair, for some the roots can be found out by trial-and-error, some are one-of-a-kind, some can be reduced to a quadratic equation. A compilation of all possible ways to solve cubic equations would be very helpful for students and learners. What is the difference between these two:     Suzuki was nearly close to go out of business just after the World War period.   Vs.     Suzuki was nearly close to going out of business just after the World War period.(from a video)   When talking about the past, do these two sentences different from each other? Like, if you use verbing(going) with infinitive(to) in the past, does it mean that there is another event happening? Or none. Is it possible to change the colors in the command prompt for the user@computer, as well as the the current directory and command parts of the prompt display?   I've already seen something like this done by OSX users, but I don't know how to do the same thing in gnome terminal (I can only change foreground and background colors).   It'd be very useful when, for example, trying to compile programs that have errors, since long, unformatted messages make it hard to distinguish which lines are commands and which are output.
