[Keith] Welcome to the Mind Of Root. I'm Keith Albright
[Rich] and I'm Rich Niemeier.
[Steve] and I'm Steve Murawski.
[Keith] This is Episode 68 recorded on September 23rd, 2008.
Chit-Chat - What's going on with you?
[Steve]
- I've been getting caught back up after being out of town for a bit. I was at the Wisconsin Department of Justice Crime Information Bureau Tech Conference. There was some pretty good sessions there, but one thing I really came away with is to centralize as much of your user accounts as you can.. Managing multiple user lists is just begging for trouble.
[Rich]
[Keith]
- I got out of the office for two days. Mimosa had a free training on eDiscovery and their email archiving solution. Rich would have loved it.
- I'm starting to believe in Karma. Or maybe I've been watching too much 'My Name Is Earl". I won software then sat in traffic.

This show is brought to you by Idera where you can get free tools –
not one, but FOUR free tools for SQL Server!! Check them out at
http://www.idera.com/FreeTools. You'll find cool free tools for SQL Server
performance monitoring, backups, permissions and more….all designed to
help you manage your SQL world. While you're there, don't forget to
download a free 14-day trial of any of Idera's award winning
enterprise products -- including SQL diagnostic manager. Our friends at
Idera are helping you manage your Windows world!
[KEITH]Have you guys tried any of the utilities? I downloaded the SQLSafeCMD? command line utility. Very fast. I'm still testing it. I've done the backups, but need to test the restore. Compression is very good. It compressed a 1 GB DB down to 300Mb and I saved it across my VPN to a remote server. My goal is to script my critical DB's to do this nightly. It's more flexible than the native SQL backup as it will only let you backup to local attached storage, not a network drive.

- Take control of your career in face of IT layoffs [KEITH]
-It's the economy stupid! Just kidding, but the state of the economy and financial sector has been the catalyst for wanting to do the peer resume review, etc.
-Item 3 - Brush up your resume. I said it last week and it still holds. Remember the peer resume review.
- Untangle for Windows [STEVE]
-Gateway server/device option using a number of open source and other applications
-New version runs on Windows desktop and uses ARP spoofing to route all traffic on the network through it.
- Ethernet Cable Segment Length and Related Topics [KEITH]
-Disclaimer:Some of the construction terms may vary by region.
-Ethernet spec is 100 Meters (328 feet). You'll hear 300 ft. commonly and this is typical of a horizontal run between your patch panel and wall jack. The device to device overall length is 328 ft.
-Why not the full 328, because you have to leave some leeway for the patch cables at the workstation and the patch panel to connect to the devices.
-Can I go over 328 ft? Yes, you can and in some cases without much penalty. Over distance you run the risk of late collisions. To understand that, let's give a brief overview on CSMA/CD and collision domains (hubs vs. switches)
-Since the collision detect algorithm knows the max amount of time for a frame to reach the other end (based off 328) if it hasn't received a confirmation that the frame was recieved, it attempts to retransmit. When it starts transmitting and then receives the late word of success, a collision (late collision) results.
-Since these will be more frequent, you are not utilizing your transmission capacity efficiently and will experience reduced throughput.
-Hubs vs. switches. In a hub, all ports are part of the same collision domain. In a switch, each individual port is it's own collision domain between the two devices. So, when CSMA/CD listens to transmit on a hub, it can hear everybody. On a switch, it listens per port. This is why switches are inherently faster. They also allow for full-duplex connections.
-So how do I know how long my cable runs are? Easiest way, is to use a network tool with TDR capabilities. It won't be exact 100% of the time, but will guide you in know if your cable length is too long. Some switches have this feature built into the port. I'm trying to remember which vendor I used that had this (Might have been 3Com)
-I won't claim to know how TDR works. I just know that it puts a signal on the wire and based on the known qualities of the medium, it takes what is received back and is able to calculate the distance.
-Decision Input Requested: -EQ with Characters
-I love this about the
PowerShell team. They are looking not only to the MVP's and internal folks for input, but since this could be a major breaking change for a number of scripts that are out there, they are asking for the communities input on this issue. If you are a
PowerShell user, you owe it to yourself to read the blog post and offer your opinion.
-This was a blog post that came about from Jeff Hicks appearance on the
PowerScripting Podcast. He makes a few points about why people might not adopt
PowerShell. I think the list is excellent and I tried to address a few of these concerns in my presentation to the LOPSA group.
4. Not asking for help

- Terminal Services for Small Environments [STEVE]
-Greg Shields over at Concentrated Technology is starting a 52 part series (weekly on Tuesdays) about Terminal Services for the smaller environments. I'll be keeping an eye on this, as I think Terminal Services might be something I can use to centralize deployment of software and resources.
- What should I load? [KEITH]
-I've got a brand new copy of Windows Vista Ultimate burning up my grubby little hands and an AMD 64-bit dual-core. What should I load? 32-bit or 64-Bit?
-I'd like to use my TV Tuner that I never got running with
MythTV? to see if I can get Media Center going, but not a show-stopper if drivers not for 64-bit.
-I've made the statement in the past that Vista should have just been 64-bit and I'm tempted to just eat my own dog food, but I'd like to hear any compelling reasons not to.

Listener Feedback
From listener....Brian
I am all for the Resume swapping suggested.
[KEITH] Brian also dropped a story on the Best Tech Implementation, so check that out as well. Thanks Brian.
I'd like to hear from more people before I try to pull this together. Let use know if you want to participate and I'll figure out a process.
From listener....Vincent
I just wanted to say I listen and love the show. I never write in to the podcasts that I listen to. Though after "in the trenches" ended I thought I should write in once and a while.
[KEITH] You know, I was thinking about that recently. I'm always asking for feedback but I rarely write in to other shows I listen to. I should try to get better at that.
