Ap with controller question
Hi,
Given the setup where i have multiple APs (LWAPP) connected to a WLC and a radius server, whenever a host connects to say AP1, when authentication occurs on the radius server, would the radius communicate with the WLC directly or with the AP?
Sorry am a bit confused, i was just thinking that the only host i should have on the radius server should be the WLC.
Thanks.
Hi,
Radius server would communicate with WLC. Your thoughts are right, only WLC is to be added as AAA host in Radius server. There is no need to add APs.
For more information please take a look at : http://www.cisco.com/en/US/tech/tk722/tk809/technologies_configuration_example09186a0080665d18.shtml#c2

At startup see a folder with a question mark
At startup I see a folder with a question mark and the system will not boot. Loaded install disk but it can not find the hard drive?
Mac Said:
Additional steps
If your Mac still starts to a flashing question mark, follow the steps below. If any step resolves the issue, you don't need to continue to the next one.
Select your Mac OS X startup disk with Startup Manager by restarting and holding the Option key. After your Mac starts up, restart again to verify that the flashing question mark does not appear.
If the issue persists, insert your Mac OS X installation disc. Be sure to either use the disc that came with your Mac, or, if you installed a later Mac OS X version from disc, use the newer disc.
MacBook Air note: On a MacBook Air, there are two options for starting up from Mac OS X media: Either connect a MacBook Air SuperDrive to the MacBook Air via the USB port and restart the computer, holding down the C key during startup, or use Remote Install Mac OS X to startup from a system software DVD that's located on a partner computer. Once started up from Mac OS X media, skip to step 3.
Restart the computer, then hold the C key during startup.
From the Utilities menu, choose Disk Utility. Don't click Continue.
Select your Mac OS X disk (named "Macintosh HD" by default) in the left side of the Disk Utility window.
Click the First Aid tab.
Click Repair Disk to verify and repair any issues with your Mac OS X startup disk.
After repairing the disk, try to start up normally.
Important: If Disk Utility finds issues it cannot repair, you may need to back up as much of your data as possible (or use Time Machine to back up to a different disk), then erase the disk and reinstall Mac OS X. You should back up important files and data before erasing a drive. Erasing deletes everything on the hard disk (including things on your desktop). Also, you can install Mac OS X onto an external disk, start from the external disk, and use Migration Assistant to transfer items from your usual internal Mac OS X startup disk to the external disk, then erase the internal disk and reinstall Mac OS X.
If the issue persists, and Disk Utility didn't find any irreparable issues, quit Disk Utility, quit the Installer, select your disk when prompted, and restart.
If the issue continues, reset PRAM. Note: After resetting PRAM, if the computer starts up normally, reselect the startup disk in the Startup Disk preferences.
If none of these steps resolve the issue, start up from the Mac OS X Installation disc and reinstall Mac OS X.
if none of this works but you have to format the entire disk, which is not very fun forsomeone, and if you have important data on your disk that you need, how do you do?
yes I have a solution, but I do not recommend it unless you know what you're doing,
ask a technician who is this he will help you safely, otherwise send a pm to me.
first a little info about me, I'm IT technician then a couple of years and have never beena fan of the mac, and will probably not be there, because I think that off "giant optimized"systems have no security, personally, I want the mac to be release an update so it forcing / or remind the user to backup with time machine, so no I will not get me one of your machines, enough about that, I had a client who had this problem, (ps / something allhave to remember is that all customers are idiots and do not know what a computer realy are, that is why it remains "the rule 101"!
His desk was this apoblemet, and I am recommending not to open up his mac becausethis would guarantee his disappearance, he had also no backups at something so long story short, he was fu ***,,
However, he had all his business accounts on the computer and much much more, so hemade the choice to give me permission to open up the machine, I went through all theguides that were on the Internet and Disk Utility was not helpful at all, nor disk Wari disc to start up, even when I plug in the drive as an external drive on another mac wanted itabsolutely does not come up.
However, so when I connected the disk in a PC with Windows 7, install a program thatmade it possible to see the disk in my computer but could not go into it because then it said that there was something wrong, but then I thought for a bit spruce, windows can see all unknown hard disk format "RAW" guidelines for adding, then it's just to make a RAW backup (google it) and Woll! now i have a copy of all his data, would also like to point out that this may take time, so be patient.
[would also like to point out that if you choose to open the your mac, there is great risk that your warranty disappear, do so at your own risk!],
so if you really have to have a backup of data you need the following;
a PC whit windows
a Controller that convert SATA to USB
a program that makes creating a driver for HFS + disks
a back-up software for RAW drives
and last but certainly not least, patience.

I got a flashing folder with a question mark. I got a new hard drive and upgraded to 4 gigs and can't open anything or reload the operating system? Help? FYI: I have been using boot camp with windows 7 and started getting a kernal_data_Page_error and it would reboot windows, i was trying to do a chkdsk on the next reboot, but thats when i started getting this issue. I have put in a new hard drive and went from 2 gigs to 4. I can not get the computer to do anything, even the monitor does not show anything now????
Prep your new drive:
Drive Preparation
1. Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs,) then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
After formatting has completed quit DU and return to the installer. Install OS X. -
White Macbook has folder with a question mark inside when powered on.
My brother has a white macbook given to him from a friend and when it is powered on it shows a folder icon with a question mark in the inside flashing and it doesn't boot. He has sent me on a quest to get a power adapter and a new hard drive, He thinks the hard drive is fried. Does anyone know for sure if thats the case, I just don't want to buy all that stuff to figure out that the logic board is dead or something else irreplaceable. There is no backup disks, all I have is a replacement leopard disk from apple used for my mac mini.
If it is a retail Leopard disc--black with a giant purple X on it--then yes, you could use them, with a couple of caveats. One, it would technically be a violation of the license to use that install of Leopard on more than one computer, and terms of use on this forum forbid me from encouraging such an action. And two, depending on how old this used MacBook is, your install of Leopard may pre-date manufacture of the MacBook and, as a result, not be able to boot the MacBook anyway. However, judging by the info in your signature, that is probably not a problem.
If the disc for your Mini is gray and shipped with or was meant to ship with the Mini, then no, the disc will not work.
I still encourage you to get the system discs that came with the MacBook originally, as they have the Apple Hardware Test included, and, as I suggested above, running any OS (or other Apple software) on a Mac without the discs means technically it's an unlicensed copy. -
When I boot up my I get a grey screen with a flashing folder with a question mark
I was trying to set up a bootable Linux flash drive for another computer using UNetbootin and I accidentally selected an empty partition on my hard drive instead of the USB I was trying to use. It went through the install process, and I didn't realize it was on my computer rather than the USB. The computer worked fine, so I thought nothing of it.
Today, I go to mess with my computer and it is frozen at the login screen. I restart it, and now I just get a blinking folder with a question mark. I try to go into recovery, but it isn't there. Internet Recovery works fine, but when I go to use Disk Utility or to reinstall the OS it cannot find the internal Hard Disk.
What am I supposed to do here? I don't want to lose all my data.greenbil1
You can contact AppleCare to buy a replacement set of the oringinal Install discs for a nominal cost. You will need the serial number and a credit card to place the order. -
I tried googling several solutions, but so far nothing seems to work. Everytime i start up my laptop i press CMND+R to make it go to the repair disk utility but instead it takes me as if i have to install lion when i had Snow Leopard 10.6.8. When i do go to the repair disk utility, on the eft hand side shows two hardrives one is Untitled and another is Hitachi, i tried downloading snow leopard 10.6.8 onto a Re-writable disc using my windows computer. When i insterted it onto the disc drive it came out under SUPER DRIVE and everytime i double click on the CD it says something about attaching images/ I also forgot to mention that the MAC OSX 10.6.8 Update shows on the left hand side on the bottom in DMG format. I dont know what else to do, please help?

This is the firmware telling you it can't find a bootable OS X volume.
Usually to solve this all you do is hold the option key down on the built in keyboard while booting the computer, this enters Startup Manager and then you choose OS X to boot, then in System Preferences > Startup Disk you change it to the boot volume and it tells the firmware.

What you have is a 10.7 or 10.8 Recovery HD from when 10.7 or 10. was on the machine previously.
The Macintosh HD partition only was erased and 10.6 installed on it, without erasing the entire drive like what should have occured to remove the Recovery HD partition.
So you have a mucked up machine.
i tried downloading snow leopard 10.6.8 onto a Re-writable disc using my windows computer.
Well there goes your problem there, your downloading illegal copies of Snow Leopard from a untrusted location.
10.6 is not available for download, except from pirate sites. You likely have malware or a compromised system.
I dont know what else to do, please help?
What you need to do is call Apple via phone, tell them the make of your machine and order the appropriate 10.6 disks, they are inexpensive now. Some machines that came with 10.6.3+ origianlly need machine specific disks, other wise pre-10.6.3 Intel Macs can use the 10.6.3 white retail disks.
Once you have the disks, you need to backup your personal information off the computer to a external storage drive using the emergency quick copy method, then disconnect it to prevent mistakes.
Most commonly used backup methods
Next follow this proceedure and make sure to select the ENTIRE drive on the far left with the drive makers name and size, this will erase the entire drive, then install 10.6 from the disk
How to erase and install Snow Leopard 10.6
When finished setup the machine and log onto the Internet and use Software Update to get current on 10.6.8
Don't use pirated software, it's likely been compromised in some fashion. -
Since upgrading to Mavericks, 10.9.1, pictures that come attached to emails no longer display. There is only a blank space that after about 1 minute, has a small box with a question mark. Double clicking on the box will open the image in a separate window. It's very slow and tedious for multiple images. How can I go back to attached and displayed images? If I click on "Forward", the images appear instantly in the email to be forwarded.
Scott,
My problem seemed to fix itself. Or, by shutting down the computer one night, instead of putting it to sleep, may have reset something. Since updating to Mavericks, I always (or usually) let the computer sleep overnight or anytime I'm walking away from it. A few days ago, I was updating notes for my kids about how to find all my stuff and how to turn on my computer, so I wanted to rewrite the start-up procedures for the iMac, just in case they ever need to. Well, I shut it down one night so the following morning, I could write down each step. Lo and behold, the images, etc. are all there again! Solved, but I'm not sure why.

I keep getting the little blue box with the question mark
Hi
I have 10.6.7 system software and my safari is 5.0.4
I have called apple twice with this problem already but nothing has helped except for short times.
I have reset safari about one dozen times and when I do I reset the top 7 items and I've emptied the cache in addition just in case. I've also taken my safari preference plist out of my library and trashed it.
And I've run disk utilities many times and restarted my computer. Each thing I do will solve the problem for a short time, even up to a day or more (or less) but then it comes back. For instance on Facebook maybe 1/8th of the thumbnail images have the little blue boxes with the question marks but most don't. I can't figure it out. Sometimes even the iPAD safari gets them too but my firefox doesn't show them and neither does Safari on my eMac.
Yesterday the question marks even showed up in ONE mailing on all 3 computers with the question marks in the blue boxes (meaning my iMac, my eMac and my iPad) but then it just all resolved after a few hours. This does sound like possibly a server problem except today it's happening (in Safari again) only on this iMac in Safari (not firefox) and not on the other two devices.
One more thing, since they changed my radio on the roof for my wireless internet, the 5.8 phone cuts out the internet when I use it. The problem has gotten worse since they changed the radio to the same frequency as the phone, it's a much faster service than the 2.4 radio. I don't know if this is related or not.
Thank you,
Martha<Contact your ISP.
Is it possible, Carolyn, that this would mainly and almost always be only affecting the iMac and Safari in the iMac if it were a server issue? Right now Safari has more blue boxes with question marks than ever and the eMac and iPad have none. Firefox on the iMac has none also.
I should try a direct connection and by pass the router and see if that makes a difference.
I will contact them tomorrow but I want to get clear in my head first all the facts and possibilities.
Thanks!

How do I get rid of the flashing file with a question mark in it?
I wanted to start clean on my MacBook Pro osx 10.9.4. So I did the command r and erased what I thought was the right one. I restarted my computer and did the command r again and what came up was internet recovery. It can't find my internet because it's WEP and I don't know to change it to wpa. So I restarted my computer again and I didn't do the command r but just let it load itself to see what would happen and all I get is a flashing file with a question mark. I don't know what to do. Someone please help me.
Do you get this display?
If so, you have to select an Internet connection. Do not expect quick response time in this mode. All activities in this mode will be lengthy.

My mac book pro does not connect but shows an error message with a question mark on the screen.I took it to a retailer that said it was not reconizing the hard drive.He said i needed a new hard drive but it may be something else as well but he was sure a new hard drive would fix it.So putting faith in someone who deals with them i purchased a new hard drive to find it was still not working although he said the computer did know reconize the hard drive and i may have to send it away to get it checked .After already paying 120 pounds for a new hard drive and they wanting another 80.00 pounds to diagnose it i am a little sceptical.
That's why i am interested on anyone's help.Welcome to the Apple Support Communities
I think that your Mac detects your hard disk, but the problem is that your new hard disk doesn't contain any operating system, so your Mac doesn't find any bootable partition and you see a question mark.
If your Mac came with DVDs, insert the Mac OS X Install DVD and hold the C key while your Mac is starting. Then, just install Mac OS X. If the hard disk isn't prepared to install Mac OS X, you will have to erase it using "Mac OS Extended (Journaled)". See > http://pondini.org/OSX/DU1.html
