comment OpenWrt: Find neighbors knowing their MAC address
As OpenMesh puts it, I think you want a DHCP reservation. support.open-mesh.com/knowledgebase/130/…

comment OpenWrt: Find neighbors knowing their MAC address
This is kind of hard to understand. The standard way would be to assign either a fixed IP, and/or a DNS hostname to the camera. If your vendor doesn't support that, you should probably give up - either because they're too stupid, or they genuinely can't support it at the moment because of whatever this mesh stuff is doing. Standard OpenWrt allows configuring fixed IPs for a given MAC (and then you can also add a DNS hostname for the IP if you want).

comment Accent error on OpenWrt 12.09?
Bug reproduced here too. Locale isn't installed by default. There are no LC_ or LANGvariables on the router either. My workstation locale is en_GB.utf8. At a guess, there was no "accent handling" at all before, but now ls has been improved not to dump 8-bit characters to a terminal with unknown locale. Or maybe it's a true regression in the ssh server (dropbear).

comment Why yum resolve dl.google.com to an IPv6 address?
@LiuYan刘研, that explanation about Yum's behaviour seems quite useful to me. It would be nice to have it as an answer - I would upvote it :). I expect there are more scenarios where google.com IPs would be inaccessible, beyond the content filtering applied by one particular nation.

comment Why do most distributions chain UEFI and grub?
I don't care about the EULA per se, but however fast Windows 8 boots, it's hardly a convenient boot menu.

comment Why do most distributions chain UEFI and grub?
This question should be put off-hold, since the hold reason given is wrong. The question does have a simple uncontestable answer: UEFI does not provide a boot menu. Some implementations do. Some don't, because in order to reach their target boot time for Windows 8, the BIOS does not even initialize input devices. Let alone wait to see if the user presses a key. So you'd have to go through Windows to get to Linux, or vice versa. The former works on some systems, but I doubt the spec guarantees it. The latter doesn't work (you can enter UEFI setup from GRUB, but not from Linux).

comment How to configure Unbound to use DNSSEC?
[Unbound: Howto enable DNSSEC [2011]](unbound.net/documentation/howto_anchor.html). But the Fedora package already does this (in the default config). So it might be you removed a line like auto-trust-anchor-file: "/var/lib/unbound/root.key" which the package provided as the default config. If that's the case then just put that line back, run sudo -u unbound unbound-anchor, and then it will work :-).

"BTW" - Manpage says you can set verbose: 3 to get per-query information into the log. Or start by finding what the failing domain is and then running dig manually to see the result code.

Where did you get unbound from? I'm wondering if you're lacking the public keys...

BTW because your local DNS cache is failing to resolve the server used for StackOverflow's CSS. Install Firebug on Firefox and look at the HTTP tab.

comment Using multiple NICs for faster internet?
This method can't work with two internet connections. It could only help if you had one fast internet connection, and two strangely slow local links.

Sorry, it's not possible to solve this question. We're trying to explain why :-). See Johnny's comment.

comment Windows 8 ask for repair when launched from grub
Note the "drivemap" error is a GRUB error. It's due to a bug where your grub.cfg is created with grub-pc (BIOS) commands, when it should only have grub-efi commands. It's a pity boot-repair didn't work for you - it seems to have helped other people with the same problem.

comment search fitting ipv6 address for MAC-Address in neighbours
The default shows both IP6 and IP4, so using -6 doesn't affect my test (makes it easier to read though :-). There's nothing in the RFC section that adds a requirement to send to all-nodes (think how "chatty" that would get!). If you want to find out your neighbors you need to send more packets, like that ping6 command does. It's easy to be misled by the grandiose name Neighbor Advertisement, but that's only really used as a unicast reply to a Solicitation. (Outside of scenarios like IP4 gratuitous ARP‌​s).

comment search fitting ipv6 address for MAC-Address in neighbours
I tried it and I don't know what you're talking about. "ip neigh show" -> no ipv6 addresses. "ping6 ff02::1%wlan0" followed by "ip neigh show" -> my neighbour's ipv6 shows up. Perhaps you could link the RFC section that explains how you think hosts broadcast^Wmulticast to local ipv6 hosts their existence using NDP. My understanding of NDP is basically ARP ported up from ethernet to IPv6 local link, it doesn't add any amazing feature from whole cloth...

comment search fitting ipv6 address for MAC-Address in neighbours
To be slightly more explicit: those commands don't send new NDP packets. They show the table of neighbours which have been recently contacted (which the kernel resolved with NDP previously). So you still need to contact them first... I'm not sure if the broadcast ping command shown in the question works for that, because you'll only be receiving IP packets from the neighbours, not sending them? Unless the neighbour's NDP then triggers a mutual discovery process? (It also assumes your neighbours respond to pings on the broadcast address).
