@scottalanmiller Nice. Have fun.

Thanks. Can't wait.

Now drinking some 12 year old Flor de Caña. Yum. Just straight on the rocks.

Normally, if you're going this extreme, I would expect to see $5k+

Actually I see a lot of people put just regular systems in fancy cases.

In that case - this case would SUCK! a normal fan on the CPU and GPU would be so loud in a case like this.

/snark Don't you mean that would SUCK and BLOW? /end snark

You forgot squeeze and burn. 🙂

An entire risk that exists only for closed source.

I hope on of the products is Microsoft Teams so they can fix the glaring functional issues with it...

Is Teams really a product though? I think of it more as a service... I mean I know they have clients for desktop and mobile... but the web version definitely feels more like a service.

I did a 2-day conference over Teams last week. It actually went very well.

It has improved a lot. It's still trails other solutions, but what from MS doesn't. It's at least starting to catch up with the level of behind that most of the rest of the MS ecosystem is.

@DustinB3403 said in Oracle Linux Installation and performance seems insanely bad:

@Obsolesce CentOS as a product is dead, the alternatives are RHEL or CentOS Stream.

CentOS Stream is a totally different thing. Not what people consider alternatives. It is an alternative in the same way that Ubuntu or Windows is.

The real alternatives that are drop in replacements that work exactly the same and cost the same are Oracle Linux, AlamLinux and Rocky Linux.

@scottalanmiller said in IPv6 New Deadline for Adoption:

At this point 2148 feels a little ambitious.

I'm hoping there's quantum communications by then. Thinking IP will be around then still I think is an under-estimation.

Perhaps TCP/QP 😄

If I meet my demise in the near future, I know my RHCSA practice session videos will live on. 🙂

And that some university might list you as faculty and sell your as the professor to their students!

We could call it something like The Office. Haha

iPhone 8 and 6Plus we could definitely use here!

Family or office?

Family. My wife currently has a 7, my daughter a 6+ and my dad a 5S. So while not a huge step up, they'd be a nice improvement and we could retire the 5S.

When working to support 911 systems we used half rack on wheels. Most very small county PSAP are to small to have a full anchored rack. They could be pushed back when access wasn’t needed, and of course out when needed.

Since emergency calls where being handled by these things, they of course had to be secure.

ETA: hate typing on the phone,....

Okay, what's the point in interviewing someone if you're not considering hiring them or offering a job? to see if they're a good fit, right?

@flaxking said in Azure or 0365?:

I'd say there's probably more roles out there to move up into. Companies may be using Microsoft 365, but could be using other providers for their cloud infrastructure. They might also expect their cloud engineers to know multiple platforms. I had experience creating highly available environments on-premise before breaking into Azure.

This is a good point. The number of M365 jobs out there probably outnumbers Azure jobs. And the M365 jobs typically need just one skill, whereas a typical Azure job will require many. And one is a logical step from helpdesk, and one is a total focus change.

@scottalanmiller said in Streaming music for office (or anywhere):

that's broadcast, doesn't apply to streaming.

When looking at the copyright issues of broadcasting (playing over speakers or display devices) streaming content for public viewing/listening in your office or restaurant, streaming is considered the same as a television or radio broadcast . So the copyright laws regarding playing TV or radio in your office also apply to streaming content.

Example: I have an IPv4 network, and you have an IPv4 network, and we want to talk to each other. But there's no IPv4 network between us. We need to tunnel our networks somehow through whatever is between us so that we can network to each other. That in between network could be anything, NetBEUI, IPX/SPX, IPv6, whatever. As long as we tunnel through it, our IPv4 networks can see each other (but not the network inbetween).

Also, the Destination for recordings is the Plex Server and its storage, so none of the recordings (that the kids have) are ever stored on the HD.

What is the best way to secure the most vulnerable attack vector for a network?

Choices:

A] Remove unneeded services running on the servers
B] Provide end-user awareness training for office staff
C] Update all antivirus definitions on workstations and servers
D] Use biometrics and SSO for authentication

Hey First Question - Thanks Scott

My first instinct D]Use biometrics and SSO for Authentication

The key words in the question is "most vulnerable attack vector" so IMHO, D] would incorrect.

Well People would be the most vulnerable

so B?

Correct, B. @scottalanmiller will have to confirm though.

I thought that too, but then I thought that was too easy and that he probably was meaning something else .

The test SHOULD be too easy. If you really know the material, and are paying attention to the reading (because the questions are designed to not let you skim them), it should feel pretty obvious a lot of the time.

@brandon220 said in Windows and NFS:

@Pete-S The locking is also what I was referring to. I will most likely set the share up for both and do some testing.

There should be locking from the filesystem so that either Samba or NFS has the file at any given moment. It's the filesystem's job to make sure that two processes can't access any given file at the same time. That the processes are NFS or Samba shouldn't matter. NFS or SMB can have another partial lock on top of that, for sure. But that should be on top of the file level lock.

That is an incorrect assumption. Read this: https://en.wikipedia.org/wiki/File_locking

Which part? I read the part of NFS, but that doesn't seem to apply. That would cause problems, but not corruption problems, right?

Just that comparing windows and *nix you see that there are different file locking mechanisms in play. That is what could cause corruption. Samba has to support Windows mechanisms while it's file system is residing on unix.

For instance from Samba 3.0 documentation (for historical context only):

Record locking semantics under UNIX are very different from record locking under Windows. Versions of Samba before 2.2 have tried to use the native fcntl() UNIX system call to implement proper record locking between different Samba clients. This cannot be fully correct for several reasons. The simplest is that a Windows client is allowed to lock a byte range up to 2^32 or 2^64, depending on the client OS. The UNIX locking only supports byte ranges up to 2^31. So it is not possible to correctly satisfy a lock request above 2^31. There are many more differences, too many to be listed here.

Samba 2.2 and above implement record locking completely independently of the underlying UNIX system. If a byte-range lock that the client requests happens to fall into the range of 0 to 2^31, Samba hands this request down to the UNIX system. No other locks can be seen by UNIX, anyway.

That's very complex. But it sounds like Samba is just... not locking the file and hoping for the best?
