If you want to run Geekbench 4 on a linux server, this is how to install and run it.
Note that you need to have a working internet connection on the server.
You can run it as root or as any other user.

Let's start from the home directory and put the files there.
cd

Download the files from geekbench.com:
(change version number if needed for latest version)
wget http://cdn.geekbench.com/Geekbench-4.3.3-Linux.tar.gz

Extract the downloaded files:
tar -zxvf Geekbench-4.3.3-Linux.tar.gz

Go to the extracted folder:
cd Geekbench-4.3.3-Linux

Run the test in tryout mode, results are uploaded automatically:
./geekbench_x86_64

After a few minutes the test is completed and you'll see a link to a webpage which is unique for each test.

Upload succeeded. Visit the following link and view your results online:
https://browser.geekbench.com/v4/cpu/1234567

Just enter the link in any browser and you'll see the results of the test.

@dbeato said in NVMe and RAID?:

One of the first Dell Servers with Hotswap NVME was the R7415 so yeah
https://www.dell.com/en-us/work/shop/povw/poweredge-r7415

Not sure what others have seen.

The newer ones have a 5 in the model number, so R7515, R6515 etc.
That's the ones you want to buy. AMD Epyc 2 Rome CPUs.

Dual sockets models are R7525, R6525 etc.

And to make this complete: 6 is 1U and 7 is 2U. R7515, R6515 etc.

@jasgot said in Macbook Air for College:

Daughter wants a Mac laptop for college. Any suggestions?

Yes, take her to the store and buy the one she wants.

Buying an Apple product is not a technical issue that needs to be figured out. It's an emotional issue. Like a Gucci bag.

If you have a RAID controller with 8 ports, you can connect up to 8 SAS/SATA drives directly to the RAID controller. That's fine but if you for instance have a server with say 36 drive bays you would need a 36 port RAID controller. Those are hard or maybe even impossible to find.

Well, here is where the SAS expander comes into play. It will work somewhat like a network switch but for SAS/SATA ports.

The SAS expander IC can be integrated directly on the backplane of the drive bays or it can be a standalone card or PCIe card. These are often used when you have more than 8 drive bays and even more so when you have 16 or more drive bays.

It allows you to expand the number of drives the RAID controller is able to connect to. It's transparent to the user because the RAID cards have integrated support for SAS expanders. This is also true of HBAs (Host Bus Adapters).

The only drawback is that the maximum transfer rate is, as always, limited by the PCIe link to the RAID controller card but also by the SAS connections from the RAID controller to the SAS expander. In real life though these bottlenecks are seldom bottlenecks as it's uncommon to read from all drives at the same time and drives are also often slower, especially when using HDDs.

SAS expanders are also used heavily in external JBOD chassis which are expander chassis for drive bays that you connect to a server so you can attach more drives than fits in the standard enclosure, aka Direct Attached Storage DAS. In that case the SAS expander sits inside the JBOD chassis.

@hobbit666 said in How to Secure a Website at Home:

Why not GitHub or GitLab for free?

That was part of the etc
Also I thought GitHub was more for storing scripts and opensource stuff.

It's not generic hosting of websites as you don't have control like you would on a normal webserver.

It's simplified hosting and the github/gitlab pages was initially intended to complement the projects on there. So it would be easy to make a html website from the git repositories, for instance for documentation.

Since you can store any files on gitlab/github you could of course also use the pages for any type of static website.

Here is how to get started in the simplest way possible:
https://guides.github.com/features/pages/

Good to know about WoeUSB.

If you have windows available, rufus is an easy tool to make bootable USB drives.
Doesn't need to be installed and it's fast.
https://rufus.akeo.ie/

But in all honesty it's very easy to make a bootable windows installer USB drive manually. Just make a primary bootable FAT32 partition on the USB drive and copy the files from the ISO onto it. Done.

You can copy more files onto the drive, for instance drivers or other software. If you do that, it makes sense to make a dd image of the entire thing when you're done. That way you can easily write a new USB drive with your custom files on it.

First, ransomware is big business run by organized crime. I think about 19 billion dollar per year industry.

Everything can be compromised in different ways. There is just no way to protect your data 100% and to think otherwise is just naive.

We have chosen to go with tape as our last line of defense. Once you take it offline there is no way it can be remotely compromised. We believe that is enough to be able to recover from most attacks and the cost is reasonable.

Integrity of files

If you want to check the integrity of a bunch of files you can do it with md5deep, which can be thought of as a recursive version of md5sum. It was initially designed for forensic work.

If a file has the same hash as another file they are identical. If you save the md5 hash of a file and later recheck it, you can be sure the file hasn't been changed, corrupted or tampered with.

Installation on Debian

You'll find it in the package md5deep.

apt install md5deep

Inside the package you'll also find sha256deep and some other good stuff. Use sha256deep instead if you want to use sha256 hash. It's better and actually more secure than md5 but might be slower. You use it in the exact the same way though.

Besides linux it's also available on other OSs such as Windows, MacOS. You can build it from source too. https://github.com/jessek/hashdeep

Create MD5 signatures

md5deep -rl /check_this_dir/* > files.md5

This will create a text file (files.md5) with the md5 hash of all files (*) in the "/check_this_dir" directory.

Check MD5 signatures

md5deep -rlX files.md5 /check_this_dir/*

It will return the files that don't match. So if any file has been changed, it will show up.

Common Options

-r is to go into subdirectories as well
-l is to use local paths instead of absolute paths
-X is to do check the signatures

-e is if you want to see the progress while it's working.

Find more info on basic usage with examples here:
http://md5deep.sourceforge.net/start-md5deep.html#basic

Example

Let's check that our files in /boot and it's sub-directories stays intact.

First let's create an md5 file that we will compare with.

md5deep -r /boot/ > boot.md5

Let's verify the files have not been tampered with.

md5deep -rX boot.md5 /boot/ 

If a file or several files has been changed it will return the file and the new hash (exit code 1).
If all is good it will not return anything (exit code 0).

Maybe stop using USB drives for things they aren't designed for?

It looks like we've been down this road before.
https://mangolassi.it/topic/20070/so-xen-server-gave-me-an-error-what-do-i-do

A small SSD would do better. Something with write endurance and something that is designed to attached 24/7 in a hot environment.

If you don't have drive bays or don't want to waste them, use satadom.

Maybe I'm alone but on the top of my list:

1. Only use Microsoft as a last resort when all other options have been explored.
2. If you get paid by the hour disregard #1.

@Pete-S said in Ubuntu Ethernet before WiFi:

So I would look at:

changing the NIC the software binds to (configuration files?)

A quick search seems to indicate that Minecraft Server have config file called server.properties .

Inside that there is a setting called server-ip.

Set that to the static IP of the computer's IP on the LAN and I'm guessing it will bind to your LAN port every time.

@hobbit666 said in Ubuntu Ethernet before WiFi:

Question,
Is there a way of getting Ubuntu to delay start the WiFi until fully booted?
But keep the ethernet as is.

I have a laptop I'm setting up, but the software I'm installing binds the port to the first nic it sees (minecraft) which always seems to be the WiFi. I want it running on the ethernet but then allow WiFi to connect so I can remote admin it over WiFi (ethernet is on different network)

I would look at differently.

The problem is not wifi, it's the fact that the software binds to the wrong NIC.
To me it's very odd that it selects wifi to bind to, since normally LAN would be the first NIC.

So I would look at:

• changing the NIC the software binds to (configuration files?)
• changing NIC names
• changing NIC enumeration order

OnlyOffice is a pretty nice alternative to MS Office. If they had an email client that would definitely be a huge plus for their product.

An email client? When would that be useful? All business email products have their own clients when needed and use web interfaces for most things (including offline handling.) Generally email clients as standalone things aren't considered a good thing (think the disaster that is Outlook.) I think no one offers one because no one should want it.
What are you looking to do with an email client? What's the use case?
I know lots of people still use Outlook because users are addicted to it. But if you are going to leave Outlook, you'd not move them to another fat client, but to the modern interfaces everyone offers.

Outlook is so much better when using the PWA version, even with it you should be getting rid of the fat client!

Not for someone who has multiple email addresses. Having to constantly click back and forth to change the user account is not ideal.

Don't have that problem with my web client. That functionality is built in.

I use Thunderbird becuase I have few email accounts, and I do not like a single web client I use(d). I do not like Gmail nor online Outlook.
I did not even knew that they support multiple accounts.
Can you name some web clients that you like, and that support multiple accounts?

(btw - I hate emails as a communication tool)

Yeah, email in Thunderbird is superior to any web client, especially when using multiple accounts or trying to do advanced stuff.

Problem is that email takes up too much time. So for common users it's better to have one account only, wean them off from email in general and migrate them to the web client or mobile app. The simpler, the better.

BTW, we use Zoho and you can integrate other imap/pop3 mailboxes as well.

Last time I tried it though I found some bugs and I haven't checked if they've fixed them yet.

@Dashrender said in Restrict access to parent folder but allow child folder access:

It's not just a list of all extensions, it's broken out into areas and departments, etc.

Yes, I imagine that would be the case for most companies.

The thing is that it would be helpful to have a system to manage it. Different companies, departments, persons or function will have different needs but a good system should be able to accommodate most of those needs with a minimal amount of work.

Integration between different system is what is need to avoid doing the same work in multiple places. The whole point of having things in a system instead of manually doing it, is to save time and provide organization and when possible automation.

I don't see a problem replacing files with better system on the technical level. But actually finding system that can get the job done without going with bespoke solutions can be tough. And bespoke software isn't cost effective in a lot of cases.

I think a paper copy only works until you're more than a page. We're still at a single page.

I think you can keep it going for quite some time - if you wanted to.

A long time ago I worked at a company that printed their own little phone book with all the internal extensions and numbers. It had maybe 30 pages or so.

@WrCombs said in Application error -:

So being told this is a windows issue, but I'm not sure how.

I've been beating my head against my desk with this for weeks now.
any advice would be appreciated.

In dotnet applications developers can build their applications against different version of .net.

As we know, the gazzilion .NET versions is a mess. So to alleviate the mess the application have config files with redirect bindings so you can decide which version of .net the application should use - even if it was intended for another version.

Since you don't have 4.0 you can try and redirect to 4.8 instead.

However you can also install 3.5 on Windows 11 and redirect to that, which I think maybe has a higher probability of succeeding. Since 3.5 is backwards compatible with 2.x and 3.x applications and it looks like your application originally required version 2.x.

There is actually a good chance that just installing 3.5 will solve your problem, because there are automatic redirects going on as well. (But undo your changes to the config file).

@Dashrender said in Restrict access to parent folder but allow child folder access:

@Pete-S said in Restrict access to parent folder but allow child folder access:

Basically what @scottalanmiller said above. Avoid "files". Let application handle the information in an organized way where the user are not going to be working with files. Only systems and sysadmins would have to think about "files".

I love the thought process here - but getting users to give up files is like pulling teeth.
Policies and Proceedures - docx/PDF - could be replaced with Wiki
Phone lists - docx/PDF - could be replaced with wiki - but people demand to print it out for faster access.
reports pulled from ERP - xlsx - what? to a custom app?
new employee paperwork - docx/pdf - HR system

Yeah, that is the problem. It's hard to find applications that can replace manual work. And most importantly, make it easier than it is to do it manually.

For example, phone numbers and lists should be pulled from databases, not wikis. I mean basically everybody today have their smartphones filled with contacts that they use to call someone. And they can't recall a single phone number because they never need to. They're all in a database.

But to automatically get the phone numbers people need into the phones they use (cell, voip, etc) isn't always so easy.

So you'd want a system that contains a database with all contacts in the company and has web access. It can integrate with whatever PBX you use and sync to whatever else phone you need contact info on. Also being able to set up "favorites" and use that info to automatically program shortcuts/BLFs on phones and sidecars for 1-button access. And also print lists of phone numbers if you need it on paper.

Does this system exist? I don't know. I've seen systems that can do bits and pieces of it but lack the overall vision.
But a lot of companies with more than a handful of employees needs something like it.

Hmm, now I'm thinking I probably should have installed Windows 11 instead...

Well, maybe not, I don't actually run it on anything else.

OK, turned out that there are actually two Education versions:

• Windows 10 Pro Education (based on Professional)
• Windows 10 Education (based on Enterprise)

Perhaps Education based on the Enterprise version is only for volume keys and Education Pro is what you get when you buy a computer that comes pre-installed with the Education license. I don't know.

Anyways, I managed to reinstall Windows 10 using the standard download media from Microsoft:
https://www.microsoft.com/en-us/software-download/windows10

Installation didn't find the product key in the BIOS so I had to install without a product key and select "Windows 10 Pro Education".

After completing the installation I wanted to active Windows. It wouldn't do this by itself.

So to activate I needed the product key in the BIOS. To get that you run:
wmic path SoftwareLicensingService get OA3xOriginalProductKey

Then I entered that key into the activation which worked perfectly.

You can probably apply the same approach to reinstall different Windows version when you have a OEM license on the hardware - especially when you have wiped or installed a new drive and you have no installation or recovery media at hand.

I have a couple of laptops that has been wiped completely and needs to be reinstalled.

I think they're OEM licensed for Windows 10 Education because they have the stickers. Is that the same installation image as Enterprise?

According to Microsoft, the Education edition is Enterprise with different defaults.
