comment How should I start MongoDB on a NUMA machine?
to set zone_reclaim_mode, simply add this to /etc/sysctl.conf: vm.zone_reclaim_mode = 0, then on system boot this will be applied. IMHO this is better as it is a well-known mechanism for setting kernel parameters.

comment Cannot resolve dns on 12.10 install
Thanks!the routes look OK, but the !H in your traceroute output means a "host unreachable". 10.0.0.28 is your local IP address and what this means is you can't reach the router, even though the routes seem fine. Can you ping the router (10.0.0.1)?

comment Cannot resolve dns on 12.10 install
@Seth: sorry, but the routes look OK, he doesn't need a static route to 10.0.0.28 which is the local IP address. Also, the asterisks (*) signifying the 0.0.0.0 (default) network don't show because I asked him to use the -n switch to get faster output.

comment Cannot resolve dns on 12.10 install
Thanks, so as the below answer mentions this looks like a deeper network problem. Could you please post output of route -n and traceroute -n 8.8.8.8? This will show whether it's a problem with the local routing table or with the router which maybe can't reach the outside.

comment Cannot resolve dns on 12.10 install
Hey! sorry, to rule out a routing/networking problem, could you also paste output of the route command, and ping -c 10 8.8.8.8 to confirm whether you can reach Google's DNS? Thanks!

Hi! Could you please update your question adding the contents of /etc/resolv.conf, and also from running this on a terminal to see where it is trying to resolve? dig google.com

comment mmc0: error -110 whilst initialising SD card
Can you please indicate your laptop's make and model? also if you could run lspci -nn and lsusb and add the output to your post it would be useful. This helps determine which card reader you may have and whether there is a known problem with that model.

comment How can I update a tar.gz file?
I corrected the command to use "z". You're right, I was giving conflicting commands (e.g. -c for create and -x for extract). I also corrected it to use uncompressed tar files based on your error message. What fails in your command is that you're not saying which tar file to operate on. It should be tar -uf docs.tar Documents/

comment Setting a Static IP address - specific issues!
Thanks for the explanation. How are you connecting to the internet? DSL? cable modem? You can configure your home router to forward minecraft connections to your computer regardless of its internal IP address, but in order to get a static "public" ip address (the one you give your friends) you would need to speak to your ISP. An easier route is to set up dynamic DNS, this way you give people a name like "schtocker-minecraft.dyndns.org" which doesn't change. Read here: wikihow.com/Make-a-Personal-Minecraft-Server

man interfaces provides a very good reference on how to configure interfaces. It's a bit technical (not a tutorial!) but is very helpful.
