Windows Server 2003 is approaching EOL.

Why are businesses so hesitant to deploy the latest version of Windows, whether client or server?

Can a sysadmin explain precisely what the risks of deploying Windows 8.1 or Windows Server 2012 R2 are?

@Bob not fair ! :P

@Bob It being up or down doesn't make any difference yannow

There's uhm nothing there :D

DragonLord

Assume the cost of deployment is not an issue (e.g. Software Assurance allows for the free upgrade)

Journeyman Geek

Change is hard. Essentially when you need to switch OSes, you need to test if every single piece of software you use works together,

And often there's a ton of custom shit

And guy who wrote it moved to another company, quit to become a trappist monk, or got nibbled to death by ducks.

@HackToHell the rest of the server is important, though

they replaced the blade, then I had to go an edit the persisted MAC addresses so it could associate eth0 with the new NIC

There's still people out there relying on IE5 (or older!) because some decade-old webapp won't work with anything else and the company that wrote it disappeared that same decade ago.

This is enabled by default on Windows Server

Not that it's hugely useful in a client environment, but it provides added information that can be used to diagnose issues starting up, shutting down, or signing in or out.

A: Can hibernating the computer damage the RAM?

Hibernation will not damage your computer's RAM. When you place your computer into hibernation, any RAM in use is compressed and stored onto disk. When you turn your computer back on, the compressed RAM image is loaded and normal operation resumes. As with most devices requiring a non-trivial a...

DRAM is refreshed continuously during system operation, so there's no way hibernation will damage the RAM.

Oliver Salzburg

> But to say that writing data from HDD to RAM can burst your RAM is the same as if somebody says that driving Ferari with a horse speed can burst Ferari engine. It can't because RAM is much faster

wat

Bob

@DragonLord Ben Voigt actually mentioned that in a since-deleted comment.

And it's a comment on the question, too...

Computers usually use DRAM so it seems unlikely as the DRAM is constantly refreshed. I means that whole RAM is read and written to about 15 times per second. So it would seem likely that any other read/write would have negligible effect on lifetime. Assume you would hibernate/resume only for 15 minutes each time - you would get 13500 writes of whole memory due to refreshes and 1 due to resume. — Maciej Piechotka 3 hours ago

But, yea, most of the answers are terrible.

Ben Richards

Heya

Hah, I wonder where that person's friend got that idea

DragonLord

And yet, those other answers are STILL getting voted up.

Ben Richards

Well then vote the others down?

I'm going to do something weird. I'm editing an answer to fix it... and then downvote it? It just feels wrong.

That Ferrari one. I get the point, but he worded it horribly.

But it's still wrong.

So anyone here very familiar with SMB/Samba performance?

A friend of mine is having an issue with performance between a Samba server running Debian and clients running Windows (8.1 or 7, tried both) and OSX.

Apparently the Windows client is incredibly slow vs the Mac.

He wrote a benchmark program to test it and I ran it against my NFS (which runs Linux, I'm pretty sure) on my Windows laptop and got similarly abysmal performance readings.

Wondering if anyone knows why and how to alleviate that?

Since it's a Samba server, it is CIFS/SMB1. Initially I thought it could've been a difference between Windows falling back to 1.5 dialect and Mac maybe using 2 or something, but the server only supports CIFS so that can't be it.

Oliver Salzburg

@BenRichards That sounds familiar... from a nightmare project

Ben Richards

19:45

@OliverSalzburg Oh?

I'll give you my numbers, and his...

Oliver Salzburg

We didn't have performance problems, just a myriad of other problems

Ben Richards

His test measures how fast it can get a directory list of the remote folder. I got (over 2 runs) 15 files/second.

That's from a Windows 8.1 laptop.

These are his numbers:
Here is the updated list:
File inodes read per second:
Native: 11214
Mac: 1297
Win7: 73
Win8: 14

Oliver Salzburg

Relating to the different SMB implementations in different versions of OSX, the inability to store OSX filesystem metadata on the host and general access privilege corruptions (people writing files and then instantly losing access to them)

Ben Richards

(Native being I guess he ran it on the server itself)

Ah

That performance disparity is way too huge to be simply due to random network conditions.

Oliver Salzburg

I agree

Bob

19:48

> SMB1 also has a compounding mechanism — known as AndX — to compound multiple actions, but Microsoft clients rarely use AndX.

Oliver Salzburg

Are you sure this is related to Samba though? As in, did you check alternate routes (FTP) to the same resource?

Bob

@BenRichards No. Update it.

Samba 4.1 supports SMB3.

Ben Richards

It does?

Bob

Samba 3.6 supports SMB2.

Ben Richards

I'm going to have to ask him what version of samba he's using. I probably was looking old documentation online

Bob

19:49

If you're running something older and forcing a fallback to SMB1, well, that's really your fault.

Ben Richards

He's on Debian so it's probably the default package. It wasn't originally built with samba in mind, but rather NFS and rsync

Bob

Might also be good to check if there's some other discrepancy forcing the MS clients to fall back.

OS X is SMB2, apparently.

Ben Richards

Yeah, I know OSX is

I'll let them know that newer versions of samba support SMB2 and 3

They didn't realize this

Bob

Win7 doesn't support SMB3, keep that in mind - but SMB2 is already a significant improvement.

Ben Richards

Yeah

Bob

19:51

Samba 3.6 was late 2011.

Ben Richards

I asked him to find out what dialect he was using from Windows though. Mine was communicating via SMB1.5

But he has a proper server, mine is just a NAS I bought from D-Link.

Oliver Salzburg

Does the SMB functional level dictate throughput?

Bob

If he's running Squeeze, well that's early 2011.

Ben Richards

SMB1 is notoriously more chatty. 2 is markedly more efficient.

Bob

@OliverSalzburg SMB2 is far less chatty than SMB1. Less round-trips, supports pipelining, etc..

Ben Richards

19:52

Though I'm not sure if that's the whole story.

Oliver Salzburg

@Bob Ah, good to know

Ben Richards

Because Windows should support SMB2, and we still have Mac being faster than Windows.

Bob

Keep in mind that original SMB (1) was designed circa 1990.

SMB2 was 2006.

In 1990, no one cared if networked file access was slow - you were lucky to have a network at all.

Oliver Salzburg

@BenRichards Just FYI, in the nightmare project, the client moved to Windows Server as a host in the end and all problems magically resolved themselves :P

Ben Richards

@OliverSalzburg Well SMB is a Microsoft thing. I'd hope so :)

@Bob Apparently SMB1 protocol was reverse engineered as well?

It was proprietary

Oliver Salzburg

19:54

I have literally never seen a Samba setup that was a convincing alternative to a Windows system, and I failed myself to produce one :(

Bob

@BenRichards There isn't a SMB1.5...

Ben Richards

Well...

It says the dialect is 1.5

Whatever that means, then :P

social.technet.microsoft.com/Forums/windowsserver/en-US/…

Hmm

openelec.tv/forum/69-network/…

Bob

@BenRichards A dialect of SMB1, but still technically following that spec.

Ben Richards

The post there says it isn't documented anywhere but MSFT did have multiple iterations of the SMB1 dialect.

nods

Anyways

Bob

@BenRichards blogs.technet.com/b/josebda/archive/2013/10/02/…

> Dialect 1.5 is a valid SMB 1 dialect and many implementations (including older versions of Windows) use it.

You see, we released many Windows versions that supported SMB1 over the years, but I did not spend any time on the blog to detail the many 1.x dialects...

We started on this last night

Me last night on twitter with him:

> unless it is just windows picking crappy default settings which isn't unheard of :P

So it could be that? ;)

Bob

20:03

@BenRichards More like Samba picking crappy default settings :P

MS probably tunes Windows clients with Windows servers in mind.

And that makes sense.

Ben Richards

What would the Samba server have to do with how the Windows client chooses to communicate?

The Mac is much faster with the same server.

Bob

I have no idea how Samba is tuned by default or what options you have, but logically they probably should have gone for maximum compatibility with Windows where possible.

Ben Richards

In that case, wouldn't the Mac have similarly abysmal performance numbers?

Bob

@BenRichards Because if the Windows client is optimised for different conditions to the Samba server, then you won't get max throughput.

Ben Richards

Because it's the same server.

Oh that's what you mean. Yeah, I understand that.

Bob

20:05

This is all speculation, of course.

Ben Richards

That's actually what I suspected. That's why I was trying to get into the nitty gritty about how the Samba server is configured and how the Mac was differently than Windows.

Without access to the machines though, I can only go as fast as my friend can on twitter :P

He's probably an hour drive from me, or more.

I ran it against my NAS, which does SMB1, from my Win 8.1 laptop and from two runs, got an average speed of 15 files/sec which matches his experience on his hardware.

So we wonder if it's something different between how the Mac and Windows are configured as SMB clients.

He is probably running Samba 3, pre SMB2 support, but no confirmation yet

OK, he's using Samba 3. Windows 7 and 8 require a turn-down on authentication, down to 40-bit, I believe, in the Network and Sharing Center -> Advanced Sharing Settings

Also, get a dump of the config file - testparm -s

Ben Richards

Would that affect performance? Or just visibility?

Canadian Luke

Take a look in the [global] section, and paste it somewhere

Ben Richards

20:47

Because he can see it fine

config file on the server?

Canadian Luke

I recall issues with lookups, each time

Yup

Ben Richards

Ok, I'll have to ask him to do so. I think he's at work right now.

Canadian Luke

Alright, no problem. I won't be available after 4:30pm PDT... Well, I will, but on my cell and with limited response time

Ben Richards

@CanadianLuke Ok. We were debugging this after 10PM EST last night anyway. :)

Canadian Luke

I got my kid tonight, so computer time is limited once I'm off work

Ben Richards

20:50

Understood

it's actually me and another friend (who built him the server in the first place) who are helping him out. The intended configuration though was NFS/rsync, but he decided to give Samba a try I guess :)

It's for backups, IIRC

Bob

@BenRichards @CanadianLuke looks like the encryption strength would cause problems earlier in the process => unixgr.com/windows-7-sp1-and-samba

Canadian Luke

Well, for ease of use, Samba is the way to go... Once it's set up properly, if you're using Windows clients

Ben Richards

Well, it's Mac and Windows as clients. :) I can actually try the authentication thing on my laptop here, since I was getting similar performance numbers as him with my NAS, which I believe runs off Linux as well, anyway.

Canadian Luke

OK, let me know. There's also a reg hack for connecting to Samba as a domain controller, but I don't believe that would be needed. Is the Mac connecting via smb:// or another protocol?

Ben Richards

Does that setting only enable the lower bit encryption and not disable 128-bit encryption?

Canadian Luke

20:55

I don't know, I can't read encrypted data ;)

Ben Richards

Ah :P

allquixotic

we need to get @Thensa in here to tell us the details on the encrypted data then

Ben Richards

Dang, we're going to have a full on task force on this problem, hah

@CanadianLuke The Mac is using SMB as well, afaik.

Unless you mean smb over http or some such tomfoolery?

Canadian Luke

Nope, regular SMB. Mounted on the desktop as a Volume, or mounted with the mount command, it shouldn't matter

Ben Richards

Ah, yeah, he said that he's doing SMB from Mac and Windows.
