zfs mirror change block size without going offline

Got pretty old physical machine which is hard to put offline for long time or rebuild. It is under FreeBSD 9, and uses zfs to store data (including system).

Don’t know why, but it confured the way that system pool status says:

        NAME        STATE     READ WRITE CKSUM
        zroot       ONLINE       0     0     0
          mirror-0  ONLINE       0     0     0
            ada0p2  ONLINE       0     0     0  block size: 512B configured, 4096B native
            ada1p2  ONLINE       0     0     0  block size: 512B configured, 4096B native

I don’t like this block size warning so I think if I can remove one disk from zroot, then add it again with new block size? But the align set on pool, not on disk, right?

Dut to fact it is quite undesirable to offline the machine for long time I try not to do send/recieve scheme, by the way.

Please advice!

Importing a private key (paper wallet) to Bitcoin Core client, while offline, is not actually importing

Trying to import a paper wallet to bitcoin core, while not having a fully synced node.
I’ve used:
importprivkey 1Lblablablablabla “MyLabel” false
It returns “null”, which I understand means successful import.

But then when I use dumpprivkey with the associated public address, it says there is no private key associated with the address.
I also look in the GUI and can’t find any clue as to where that private key has been imported.

So basically the wallet is not giving me errors of failed import, but also not actually importing the private key.
What should I do?

How to – Installing Workflow manager 1.0 CU2 refresh without connecting to internet – offline install

Whats the procedure of installing the workflow manager 1.0 CU2 REFRESH version on my SP 2013 SP1 environment on my server thats having Win 2012 R2 OS.

I tried to run the s/ws that are pre-requisites for the wf manager cu2 refresh and kept it in my D: drive. whenever i tried to run those s/ws , it will directly connect to internet and download using the web platform installer 5.0 and download those pre-requisites.

Is there any step by step procedure using the powershell using the EXEs placed in the d drive and install WFManager CU2 REFRESH ?

my company doesnt allow me to download and install using the web PI.They wont allow direct online install of s/w to my desktops or servers.

licensing – Strategies for migrating node-locked, offline license data?

I have a piece of software which I would like to grant node-locked licenses for. The acquired license files will sit locally on licensed computers and should not require an internet connection to validate (but will require an internet connection to acquire). The software will validate the license file using common techniques involving comparing the machine’s hardware ID to the license data…usual stuff not relevant here. The license itself should be perpetual (until de-activated).

The question I can’t figure out is how to allow customers to transfer their license to another machine. Let’s say they have a valid license data file on machine A. I provide a tool or web portal which allows them to transfer their license to machine B. The tool loads up and does X, which tells the license server to free up a license, allowing them to download a new license file for machine B. When the process completes, machine A no longer has a valid license and machine B is licensed. The transfer is complete.

The mystery involves what X could be. How do I de-activate a license file without the user simply being able to restore the license file afterwards, thereby circumventing my transfer process? A naive approach to X would be to simply delete the local license file and then inform the server that the license file no longer exists on machine A. But what is preventing the user from saving/restoring a prior backup? Having licenses expire and thus require renewal could prevent old licenses from being re-used for too long, but the ideal solution would only require a single activation per license, until de-activation for transfer.

This seems like a solved problem, because I know of several large companies which allow node-locked license transfers like this…but I have no idea how they’re doing it. Is there a clever way to ensure that users cannot simply restore license file data on de-activated machines?

icloud – How to force Books to keep local files offline?

I have many PDF and epub books that I have manually added to my Books library. However, when I try to open them, many times they have to be downloaded from iCloud because somehow they were uploaded behind the scenes and deleted from the local drive. How can I prevent this from happening? I haven’t found anything in the settings allowing me to do this. I want to keep syncing on because I want the books to also show in my mobile devices, but I don’t want the books to be removed from the local drive when they’re uploaded to iCloud. I want to always be able to access them offline on my laptop. Is this possible?

c# – Aplicação .NET online + Offline

É o seguinte, há hoje alguma forma ou ferramenta que permita gravar os dados em um banco offline caso a internet do cliente caia? Vou explicar melhor, a minha aplicação é Web, feita em .Net, roda totalmente do Browser e a princípio, vai gravar tudo no banco online, mas e se a conexão do cliente cair? Eu precisaria que esses dados fossem gravados na máquina do cliente localmente, para quando a conexão voltasse, todos essa informação armazenada localmente fosse lançada no banco de dados online. O que vocês acham?

Obrigado.

dism – Install “Media Feature Pack” on Windows 2009 (20H2) – OFFLINE

I am trying to figure out if it’s possible to install the Windows Media Feature Pack on a Windows 10 N computer, build 20H2 whilst being offline.

For versions of Windows 1903 and below you could download the Media Feature Pack as an .msu file and install onto a PC without it being connected to the Internet.
https://www.microsoft.com/en-us/software-download/mediafeaturepack

From build 1909 onwards you are required to install the Media Feature Pack from Settings > Apps > Apps and Features > Optional Features > Add a Feature.
https://support.microsoft.com/en-us/topic/media-feature-pack-for-windows-10-n-november-2019-aaf0e378-8828-78d9-b91d-e378f82f252c

I thought the feature may have been included as part of the Feature On Demand (FOD) ISO, but the Media Feature Pack is not listed in the following article.
https://docs.microsoft.com/en-us/windows-hardware/manufacture/desktop/features-on-demand-non-language-fod

I also tried setting “The Specify settings for optional component installation and component repair” policy on the client, and as described in the URL below configured the “Alternate source file path” to point to a Windows 10 (non-N) WIM file.
https://docs.microsoft.com/en-us/windows/deployment/update/fod-and-lang-packs

Optional component installation GPO

I have also tried to install using Powershell, pointing to the content from the FOD ISO and a Windows SXS folder from a non-N version of Windows.

  Add-WindowsCapability -Name Media.MediaFeaturePack~~~~0.0.1.0 -Online -LimitAccess -Source \ServerShare$FOD

  Add-WindowsCapability -Name Media.MediaFeaturePack~~~~0.0.1.0 -Online -LimitAccess -Source \ServerShare$WinSXS

Please can somebody help me understand if this is in fact possible and if so how to do it.

Any help greatly appreciated.

c# – Offline user authentication

The pen testers suggested using a token system where the user authenticates with the server and it stores a token in the local database which would be used while offline, but I don’t see how this solves the decompiling issue. Surely this could be bypassed in the same way?

Right, you could make a modified version that ignores the token.


Is my only option to tell the customer that if they want the application to be secure, then it can’t work offline?

I don’t know what secure means for the customer. Remember that your the customer is somebody who has the right to access anyway. Thus modifying the client to get access is probably not an issue. Less secure for the customer? Only to the extend that the customer does not know what they are doing. You can say in end user agreement that they lose support if they do it, and you are not liable for damages.

Next, consider a third party getting access to the machine of the costumer and modifying the client… Well, you can say that protecting the machine from physical access is their responsibility, and again you are not liable for damages.

I believe, instead, we should be talking about somebody who is not the customer getting an illegal copy and modifying it to get access. But that is not security of the customer anymore.


Thus, let us make it harder for a third party who got a copy to get access. Yes, the token helps in that case, but not really. If all that the client needs to work is contained in it, then it is a matter of invalidating the right conditional in the code.

I want to mention something stronger than the token idea: You would make custom packages cipher. The key to decipher them will be derived from a hash of the password (you may add other ingredients to the dish, such as activation date, user name, salt and pepper to taste). These packages will be necessary to work, downloaded from the server, and decipher locally.

Note that a malicious customer might be able to repackage them to create a version of the client that does not require this steps to work. Albeit much harder that the case that just requires to invalidate a check somewhere in the client code. And also, this requires a valid customer, not a random person who got a copy.

Of course, once these copies are online anybody would be able to use them. For that, only online authentication works.
