Hi,
I'm new in this forum and in that environment.
I'm searching some solution to data acquisition 8 channels of audio. Firstly, I want to try to read the audio PC card and view that data. Can you help me how I can start this acquisition?
I don't know how I can do it.
Thanks,

Yesterday I ran into a oddity that might be handy for some folks.
Recently a SCADA system PC crashed on me, one which we purchased fully integrated and with no documentation. I bought a new Win7 box to replace it, recovered the hard drive, and copied all the files I thought looked related to the SCADA system. I called the manufacturer, but they refused to talk to me, and insisted that the licensing and configuration had to be done by the company that integrated the thing for us. After much haggling, I finally got that outfit to consent to 30 minutes of telephone support.
In the course of setting things up, one of the tasks required was to add a System DSN used to establish ODBC connections to the .mdb database used by the SCADA product, so I opened up the usual ODBC Sources applet in Control Panel. Surprisingly, only SQL Server was installed and available for use - no other drivers were listed. I've never seen that in a Windows system before.
After much gnashing of teeth and rending of clothing, the support guy stumbled on a link somewhere that suggested running an obscure program located at C:\Windows\SysWOW64\odbcad32.exe. I don't know where he found it, but running it produces a ODBC Sources applet identical to the one reached through Control Panel, but containing all the usual sources. From that point on, it was an easy setup, but I would never in many years have found that ridiculous hidden tool.
No I have to wonder, what other missing functionality is hidden in this folder? Any other hints?

I remember reading an article about it a few years back. There were some more examples besides ODBC that was hidden the same way, can't remember which ones though.
It seems that when Microsoft drops support for a product (in this case ODBC) they don't actually drop it immediately, they just make it "invisible" for developers so that they won't use it for new products. But they remain available, with some tweaking, for a couple of versions so that they don't lose sales to people in exactly your situation.

Ahh, that's the 32 bit ODBC manager. Basically, on a 64 bit machine, you can have 64 bit and 32 bit ODBC drivers installed. The normal place to look for the drivers is in the 32 bit version, but the actual ODBC applet that runs is the 64 bit one. This is why I have a shortcut to odbcad32 on my desktop.

Thanks! Handy information to have, especially with so many Access-based products still out there. Fortunately, no one is still running any of my Paradox stuff anymore.

Can someone help me to interpret what's going on here?
My Junk Mail folder is filling up rapidly with email rejection notices. This has been going on sporadically for a couple of weeks, with a flurry of several hundred such messages, then a trickle, then none for a day or two before it starts again. A typical message is:
This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:

The only constant is the reference to "bosxxxxxxx.eigbox.net" in the middle portion of the message header. Everything else in the message changes at random, and the IP addresses associated with my email address don't match anything I've ever used. What is doing this, and which server is compromised? Should I notify the admin for the eigbox.net domain that this is going on, or is that being spoofed, too?
My concern here is that some of the dumber blacklist algorithms might block me widely because they use the spoofed email address instead of examining the IP address. This small flood is a sign to me of a much larger iceberg melting (global warming, perhaps?) with only the tip showing up in my mailbox. Should I be concerned?

Hey Roger,
It looks like someone in northern Spain is sending out bulk e-mails and the Yahoo server is rejecting them. The mails are most likely originating from an innocent individual infected with a botnet mailer.
There is a little more to it than that... based on the mail header you posted... it appears that the mail server at bosauthsmtp01.eigbox.net is a misconfigured mail server. It looks like the assigned ip block where the mail server lives is 38.113.1.0/24 and is owned by 'Endurance International Group' according to the records[^]. The registered AS number for that IP block is AS29873[^] and you could attempt to contact them. In my experience... nobody every responds to abuse complaints unless there is a warrant attached.
The reason nobody responds to complaints probably has something to do with the fact that poor little Brian appears to be responsible for 79,461[^] domains within that ip range. And thats just one of the 51 ip blocks he appears to be responsible for.
Roger Wright wrote: Should I be concerned?
There isn't much you can do about it... the SMTP protocols were not very well designed and the protocol allows spoofing. It is up to the mail server software to prevent this. Your ISP or web hosting provider should be diligent with keeping the mail servers properly configured.
By the way you should probably remove your rawright.net[^] e-mail address from the mail header you posted. But because you left it there... I was able to determine that your domain name rawright.net at 66.96.146.82 is on the 66.96.128.0/18 ip block[^] which poor little Brian is responsible for[^]. I hope you don't mind... I hacked, probed and prodded your box a little bit... and it appears to be running IIS/6.0 on windows server.
Some thoughts:
I was able to connect to your rawright.net SMTP port 25 and forge my origin domain. The SMTP server did not complain. A well configured an e-mail server will perform a reverse DNS here and make sure my IP address matches the domain from the HELO command. I connected multiple times and each time I was routed through a different *.eigbox.net smtp authorization server. It looks like your service provider is using some sort of round robin BGP/GLBP routing.
I spent a few minutes manually testing your mail server via raw TCP socket but always recieved the error: 550 bosauthsmtp: Host x.x.x.x: No unauthenticated relaying permitted (I used all of the tricks I know about and was unable to trick the server into allowing me to relay mail. This is what we want). So maybe its already fixed. But maybe it is not fixed... if you look closely at the mail header you posted... it says the spam came via ESMTPSA which means the spam was sent over an encrypted TLS[^]. Although I would probably continue testing via TLSWrap[^]... I think I'll not test any further. It may be that their plain text SMTP server is well protected... but the encrypted SMTP is vulnerable.
Anyway we could speculate about this all day... but the best person to handle this would be a systems administrator from your rawright.net hosting provider.
Best Wishes,
-David Delaune

I thought I'd removed all those references. 
I'm quite impressed by the amount of information you were able to glean. FYI, I don't control the SMTP server - webhost4life.com does that. Perhaps it's time for another move, painful as the last one was.

I am coming from the business side rather than from the IT side, but I have been asked to solve a business problem that I think is totally common nowadays, and I hope you can help me with some system admin solutions.
I need to know if my idea will work and it would be very helpful if you could point out some problems areas that I need to consider.
We are a large international organization with a Microsoft infrastructure and about 200 staff who travel frequently. They typically use laptops we provide, but also they want to use their own devices (Bring Your Own Device = BYOD) such as iPads, Macintosh laptops, smartphones, Android tablets, you name it.
What I would like to say to our staff is this:
"Your work computer will be a laptop that you can take home with you or take abroad on your travels.
When you receive this computer it will come with a set of standard software installed, including anti-virus software. Thereafter you have admin rights over this laptop, you are completely responsible for everything on this computer, including backups, just as if it were your personal property. When you leave our organization, you turn your computer in.
"You store your work on your own computer, so you are responsible for backups. If you finish something that should be shared with your colleagues, you upload it to our corporate intranet online, and you let people know it’s there.
"When you come to the office, you will be able to plug your laptop into a docking station with a large-screen monitor and a keyboard. You can log into our network on your office computer, but not on any personal device.
"If you want to access the Internet or printers with any device other than your office laptop you can do so wirelessly."
What do you experienced System Administrators think of this approach. I know our staff would love me for it because they have some big problems with the security of our network, because they can't BYOD, they can install personal software on their laptops, getting software updates is a big hassle with the IT department, etc.
Thanks in advance for your help!

And I suspect your IT department and company lawyers would hate you. IT security is a very serious business and in any corporate organisation it is important to keep good control in order to protect your financial and intellectual property. If you open up your corporate network so people can hook their own systems into it whenever they like, then you are likely to face some serious issues. However many promises people make and however many rules you ask them to follow, the system will be abused.
My advice, don't do it.

Depends on the network setup. At the customer site I work at, the wireless and office network are 2 distinct and separate connections to the Internet. When connected to the wireless there is no connectivity to the servers available unless you connect in via the VPN or have a Domain connected laptop that uses Direct Access to connect in from anywhere.
If the Wireless and Wired network are all running off the same Internet connection and internal network, then like you say, runaway.

In addition to our desktops we employ this setup for our laptop users. This is becoming more common as the power and memory capabilities increasingly are cheaper.

Again this is a great idea, but I would advise using some form of encryption. Bitlocker works well, but it depends on what OS you're currently using. They're are other software based encryption programs to use w/leagcy OS'. This still can create an issue as the user almost never do backups or willingly run AV scans. As long as you're using Active Directory you could push out Forefront and do Bitlocker key recovery. They still download willy-nilly programs like RegReviver and what not, but this gives you a stance on giving them an ultimatim. Either you behave with it, or we'll just re-image it when you screw it up. This tends to stop a lot of the BS downloaders, but not all of them.

We do this as well and it works very well, as it exists on an external network. This can present some issues too if you're in a building close to other businesses or the public I guess. We're fortunate to be "out-of-town", but I think this would still be an answer for the BYOD'ers.
Something worth reading, albeit it's invincible!

I just tried using Remote Desktop Connection today, accessing important apps on my desktop from my laptop, and it works great. But that was between rooms, using my home workgroup and the desktop computer name as the target, connecting over the wireless LAN. Now I want to go to the next level, and do the same over the Internet. The MS instruction fall a little short of covering that configuration. Here's my setup:
Internet -> cable modem/router -> Cisco/Linksys E4200 wireless router -> Wired connection to desktop, wireless to laptop.
The only routable IP address in the lot is the WAN address on the E4200, which is bridged from the cable modem. It's dynamic, and that could be a problem, but it wouldn't be too difficult to write a service on my website to allow me to look up the current IP address anytime I'm travelling. It hasn't changed in a couple of years, so that's not an immediate concern. What is a concern is that I don't know how to configure the laptop to connect to the home IP address, nor what ports and services I need to enable on the router to move RDC traffic from the router to the desktop, and back to the laptop in my hotel 300 miles away.
Can someone point me to the information I need to accomplish this?

Services like dyndns.org allow you to get your IP address from a name, thus you can do a ping your-computer-name.dyndns.org.
To get from the internet into your private home network, you must configure port forwarding on the router.

Thanks... I found a website with instructions. There wasn't a whole lot of info from MS about which ports and protocols to enable, but the site gives a few clues.

Roger, port 3389 is what you want for RDP but I would not want to open that up on my router and expose my network to the internet.
I'd seriously look at getting a little, low power, low heat output box, put a Linux Distro on it and SSH to the Linux Box (reasonably locked down) and SSH Tunnel through it to the Windows Boxen, Routers, Website stuff like your USB HDD.
I reckon you could easily work it out, but I could happily help you through, even give you a call on a landlne (if you have one) cause I can call you Yanks for free except for mobiles.
