Outgoing TCP connections from VM have very low firewall state idle timeout -- how do you adjust?

When I create a TCP connection from a VM to the internet, if I'm idle for more than a few minutes (say a SSH session), the TCP flow is torn down by some AZURE networking element in between.
Incoming connections from the internet in don't seem to be affected.
I assume this is an Azure firewall timeout somewhere.
Is there any way to raise this?

Hi,
Thanks for posting here.
Here are some suggestions:
[1] - You can make sure the TCP connection is not idle. To keep your TCP connection active you can keeping sending some data before 60 seconds passes. This could be done via chunked transfer encoding; send something or you can just send blank lines to keep
the connection active.
[2] - If you are using WCF based application please have a look at below link:
Reference:
http://code.msdn.microsoft.com/WCF-Azure-NetTCP-Keep-Alive-09f50fd9
[3] - If you are using TCP Sockets then you can also try ServicePointManager.SetTcpKeepAlive(true, 30000, 30000) might be used to do this. TCP Keep-Alive packets will keep the connection from your client to the load balancer open during a long-running HTTP
request. For example if you’re using .NET WebRequest objects in your client you would set ServicePointManager.SetTcpKeepAlive(…) appropriately.

Hope this helps you.

New iOS 7 is very difficult to see screens. How can you adjust contrast?

I upgraded my iPhone to iOS 7. How can I improve the contrast on all the screens and apps. Most screens are all white or very light with smaller text and I can barely see anything, especially when out in the sun. Is there a setting to change or a way to improve the contrast?

Settings -> General-> Accessibility -> Increase Contrast
You can also turn on the setting for Bold Text. Those two options should help at least somewhat.

IDT High Definition Audio CODEC v. 6.10.6395.0 Upon installation I have very low audio output

IDT High Definition Audio CODEC v. 6.10.6395.0. 5/21/ 2012
Upon installation I have very low audio output! Screen Shot Screen Shot 2
I have tried:
un-installing and reinstalling the drivers.
Installed the original drivers via HP's website sp53222 for my particular model. HP Pavilion HPE h8-1070t
Any suggestions? would be greatly appreciated. It would appear IDT who I also emailed and they never responded is responsible for a codec pack that is not fully functional with this motherboard.

Did you access the Catalyst Control Center in programs and look at the latest updates for your graphics card and make sure you didn't download the audio drivers they self install and are checked automatically each time you attempt an update for the card.
Did you right click on the speaker in the system tray and go into recodring devices make sure everything is setup propper there sometimes they too can change.
I'm familiar with cakewalk but never used it on Win7 its been many years since I played around with that. If you are using the onboard audio card and it has worked before and not now if I were in your situtation I would attempt to reisntall the dirvers via device manager they do sometimes become corrupt especially if you picked up any malware that was removed by your antivirus software due to the drivers and malware both reside inwindows\system32.
After the reisntall of the drivers if the issue is not resolved I would upgrade the audio card with a PCIe x1 component such as:
Creative Labs SB1040 PCI Express Sound Blaster X-Fi Xtreme Audio Sound Card
http://www.amazon.com/Creative-Labs-SB1040-Express-Blaster/dp/B000W7PNZI/ref=sr_1_1?ie=UTF8&qid=1357...
After I paid for a real soundcard with Recording: 24-bit/96kHz and Sound Output Mode - 7.1 and bypassed my onboard audiocard I never had any issues again. My onbaord worked too in the begining for certain things than stopped mysteryously and the reinstallation became ineffective after a while so I decided the money for the tower was invested mainly in the CPU i7 the RAM and HDD.
*** Note if you did install the audio drivers for the graphics card you will have to change the onboard audio in the BIOS from automattic to enabled. Otherwise you will have no sound at all. So never take the audio drivers for the graphics card unless you need them for DVR recording or something. The PCIe audio cards are never effected by this however only the onboard audio. Another reason onboard is a cheap way to go and HP bundles it as cheap as it can my friend.
Good Luck again!

Hi Roger:
Thanks for the reply. I think I figured out the problem. Apple has confused (at least in my mind) the different IDs that people can have. In the iCloud settings, they use the term Apple ID and not iCloud ID. I guess there really is no such thing as an iCloud ID. There are Apple IDs with various attributes. This is not clearly explained or easy to see (how could I look up to see if my Apple ID is associated with iTunes for example?).
I created, what I thought were iCloud IDs for each family member, but we all use my Apple ID for iTunes.
One other question - why does the syncing of Notes using iCloud require an @me.com email account. That makes no sense to me.
Thanks for your help!

I Have 100's if songs on my iTunes Mac Pro that have the available to download icon. How do you get them all to download?

Open the iTunes Store. From the music section of the store, click on the "Purchased" link on the right side about halfway down.
Click on the "Not in My Library" tab toward the top.
Finally, click "Download All" in the lower right.

Want to connect an older Amplifier to AEX. Input data is 200mV for the amp. When I connect sound level is very low. What is output on AEX?

Want to connect an older amplifier to AEX. Input (AUX)data is 200mV. The soundlevel is very low. What is output from AEX? Phono input is 2,5mV and gives too high soundlevel as well as a strange sound(Isuppose some preamp is there)
Anyone to give some good ideas?

The analog output of the AirPort Express is approximately the same as a CD player. It is definitely compatible with a millivolt input. Don't use a phono input.
Make sure the master volume in iTunes is at its maximum setting. Remote speakers can have their own volume setting in iTunes, so check that also:
Try another audio cable.

Hi helpers I have very old MacBook 10.5.8 please could you tell me what operating system I should get to be able fully use my laptop as i cant use it properly anymore and doesnt connect with my Iphones etc thanks

Hi helpers I have very old MacBook Mac OS X 10.5.8 please could you tell me what operating system I should get to be able fully use my laptop as i cant use it properly anymore and doesnt connect with my Iphones etc thanks

Josejanko,
You don't supply much info other than your machine is old, so here is some info for you to check thru.
Before doing anything you should have a back up, preferably 2, in the event something goes wrong.
You would have to start by upgrading to Snow Leopard, you would need to buy the disk for about $20 here http://store.apple.com/us/product/MC573Z/A/mac-os-x-106-snow-leopard
Check the the requirements to see if your machine meets them.
You would then need to run the 10.6.8 v1.1 combo update to get it to 10.6.8 Mac OS X 10.6.8 Update Combo v1.1
You can then access the APP STORE and possibly upgrade to to further OSX.
You may have applications that will not be compatible with any thing past Snow Leopard, you can check those here Upgrading to 10.7 and above, don't forget Rosetta!
http://roaringapps.com/apps
Office 2008 will not work with anything newer than Snow Leopard for an wxample
You may be able to upgrade to Lion or MT Lion or Yosemite, depending on your machine, from the APP STORE.
OS X Lion - Technical Specifications Lion

Hope this helps you

HT1751 I've read at least ten articles and I still have some unanswered questions. 1. How do you get several libraries on an external disk back into one spot on Itunes? Will it take up space on the Mac osx that I have very little space on?

I have several itunes libraries after moving them and losing them, and recreating new ones. How do I get them all back together? I have a Macboook Pro OSX 10.6. My newest library is currently being directed to an external drive. I have files that I moved around improperly and don't know where they all go now. I'm pretty good with it all if someone can explain. Nothing I've read explains how to find your lost libraries on an external drive and put them into one place.
If you have it on an external drive and do not have the space on the hard drive can you still do the library/organize/consolidate feature and have files available without the external drive attatched? I just don't know how I will get all the files into itunes without taking up a bunch of space.
Thank you so much!

I'm confused as to why you would need or even want multiple iTunes libraries... but that's not really relevant.
It certainly is possible to have the iTunes library reside entirely on an external drive.
The organize/consolidate feature will work with an external drive but the drive must be connected. How would you expect this to work without the drive connected? iTunes cannot magically move files to consolodate them on a drive that's not connected.
I"m not really certain what you mean by "get them all back together". iTunes libraries are not "together". If you've got multiple libraries they are seperate...there is simply no other way to make that happen.
Realistically, if this hasn't helped, it's going to be up to you to explain why you have/need multiple iTunes libaries so that we can offer specific details on how to resolve the issue and possibly a better solution.

How do you permanently delete apps from all your mac products (MacBook Pro, iPad, iPhone), how do you permanently delete apps from all your mac products (MacBook Pro, iPad, iPhone)

how do you permanently delete apps from all your mac products (MacBook Pro, iPad, iPhone)

They are not taking up storage space. Apple knows you installed them at one time (="purchased", whether you paid money or not), and merely keeps a list so that if you wish to reinstall any of them on this or a future device, you can. This is useful if maybe you deleted them due to space constraints, and now have a device with more memory and wish to reinstall.
It's also useful for taking a trip down Memory Lane looking at all the useless apps you installed once then immediately deleted once you realized they were total garbage ...
