Booting from a tar file

Hi
I have to install a new version on a AP and i just downloaded a .tar file from Cisco.
My question is, can i boot directly from that tar file?
I never tryied this and before doing something wrong i want to be sure it will work. I read somewhere that maybe i have to uncompress the file firt but the AP seems it doesn't have this option.
Any help will be great, thanks

What files do you have in your flash memory? Can you list them on here.
Is the AP still accessible over the network?
Did you load the .tar file directly onto the AP?
If so then it will not boot with this file. a .tar file is the Cisco equivalent of a ZIP file. Before you can use it you need to "unzip" it. The problem is that the AP doesn't have enough memory to hold the .tar file and the unzipped files. Your best bet may be to copy the .bin file from one of your other access points onto this AP to get it to boot, then use the command in my original post. I've used this command on 130 AP1200s without a single problem.

Extracting file from a TAR file with java.util.zip.* classes

Is there a way to extract files from a .TAR file using the java.util.zip.* classes?
I tried in some ways but I get the following error:
java.util.zip.ZipException: error in opening zip file
at java.util.zip.ZipFile.<init>(ZipFile.java127)
at java.util.zip.ZipFile.<init>(ZipFile.java92)
Thank you

download the tar.jar from the above link and use the sample program below
import com.ice.tar.*;

Attempting to Boot From, no configuration file found

I started digging out some of these older desktops and the first one has me stumped.
HP d3225 Minitower XP Pro
When I insert usb I get this message: No default or usb configuration directory found. Can someone advise please?
Thanks in advance!!

Does this happen only when the USB devices are inserted and is the PC booted or are you trying to boot from USB?

Making .tar.gz from .tar file in linux

i had a doubt as to how to create a .tar.gz file from a .tar file in linux as i wanted to take the back-up of the export of Oracle. Please, help in solving the doubt.
regards

It's the gzip command:
http://linux.about.com/od/commands/l/blcmdl1_gzip.htm
Also note that Oracle Database 10g provides the new UTL_COMPRESS
package to compress and uncompress data, with the compressed output compatible with the output of the familiar GZIP and GUNZIP compression utilities.
Hope this helps. . .

Optical drive trashed and MB Pro will not boot from USB image

Hello,
New here but I have searched and tried all I know to get this MBP working right again. My disk drive is trashed and has been for some time now, this is why I have a bootable version of Snow Leopard on an 8G flash drive. When my MBP began acting funny recently and I went to disk utility to verify permissions and the disk. Both failed = must boot from disk to repair, thus my issue. For some reason by MBP will not boot from the usb image I have used previously??? Pressing C or Option during startup does not work. If I press Option, I only get the harddrive option, C yields nothing and the computer boots normally.
Please!! let me know how / what you would do to resolve this. I don't understand why I have previously been able to boot from this same file on the same drive previously to repair my disk / permissions but cannot do so now. FWIW, I tried placing the file (OSX) on my external HDD to boot from, this did not work either (USB HDD).
Thank you in advance for your input!!

It isn't clear what you mean about your HD being trashed or which disk (HD or USB drive) you are trying to repair, but either way you need to start up from your Snow Leopard installer DVD & instead of installing anything go to the Utilities menu & run Disk Utility from there to repair either or both of the disks.

Read TAr File - JavaTar

Hi, i am new to ICE (javatar) library to read files from a tar file.
I have a tar file with a lot of file inside
for example
example-file.tar
insidefil1.xml
insidefile2.pdf
and i need to read each of one file into an individuals InputStreams (for exmaple to parse the xml file). But i not allowed to decompress this tar to a temporary folder. How can i do it ? i see no exist anymore the copyContent in the tarEntry
     public List readFiles(InputStream io) throws IOException{
          List l = new ArrayList();
           TarInputStream tin = new TarInputStream(io);
           TarEntry tarEntry = null;
          while((tarEntry = tin.getNextEntry())!= null){
                 //Here i want to read ech file inside the parent tar file
               System.out.println(tarEntry.toString());

Susan you will need to install the complete device pack. The reason being its not just firmware, the device pack contains all files needed to add the support for new phones. You will need to install the device pack on all nodes and reboot the cluster.
Follow below instructions from readme:
http://www.cisco.com/web/software/282074299/119109/cmterm-devicepack8.5.1_17133-1_Release_Notes.pdf
Please also note when you apply device pack it will update firmware of all devices. There are ways to stop that, just search this community if you dont want to let that happen.

Need help booting from DMG file without DVD drive

okay so i have 6 computers with me right now. i need to use one that has a dvd drive to install it on a comp that doesnt via firewire.
1- macbook with superdrive and os 10.5 (cant even open tiger install because its a new macbook
2-iBook g4 with DVD drive BUT the firewire port is broken
3-iBook g3 (one that needs tiger but only has a cd drive)
4-ibook g3 (without dvd drive)
5-powerbook g4 with dvd drive and firewire (for some reason will not read the tiger discs i just burned, even though ive already used them on the ibook g4
6-mac pro with firewire and dvd drive, but the dvd drive is broken.
so seems to me, every computer i have has a weakness for exactly what i need. what i need to know now is if i can boot the powerbook g4 from a DMG file of tiger install disc 1 and install is to the target ibook through firewire. if you have any suggestions on what i should try with the supplies mentioned above, please inform me. thanks!

what i need to know now is if i can boot the powerbook g4 from a DMG file of tiger install disc 1 and install is to the target ibook through firewire.
You can't unless the PowerBook is running Mac OS X Server, in which case the NetInstall feature can be used.

Grey Screen, won't boot from usb. Only have a PC to create a boot USB. How can I reinstall OSX with a .dmg file?

I recently recieved a macbook that I was told was broken. She didn't know what was wrong with it, but she told me I could keep it if I wanted to get it working again. Its http://support.apple.com/kb/sp579 this model. I got the laptop to power on, but the apple logo and the spinning wheel under it kept spinning forever. So with me and my "Amazing" knowledge of Macs, I thought it would be best to reformat the drive on my PC via sata cable to FAT32 (which I was told is a format that mac devices can read/write on) and install OSX from usb. So I have a .dmg file and used TransMac to format the usb and make the usb drive bootable with the .dmg.
I formatted the drive to FAT32 and plugged it into my macbook and I get a folder and a question mark blinking on the screen. After looking at some forums online, I found that the error occurs when you don't have the correct filesystem to boot or something along those lines. So I try rebooting the computer while holding C, to boot from an external device (such as USB). Nothing. Again the folder and question mark blink on the screen. I look at some other boot option keys and try all of them. Shift for recovery mode, D for apple hardware test, Control, option, P, and R for resetting NVRAM and PRAM. Everything! The only things that differ slightly are when I press Option for startup manager, N for NetBoot and Option+N for internet default boot image. When I press N and Option+N, I get a blinking globe for about 5-10 seconds and then the folder and ? blink again. When I hold Option for the startup manager, I get a white screen and my curser, which I can move around the screen, but there is nothing to click on, its just white.
Currently I have a USB flash drive plugged into the macbook with a .dmg OSX installer on it via TransMac and for some reason, my macbook doesn't want to try to load it. Either I have the wrong file format for the installer, or my macbook is having problems. I read that the hard drive may be the problem, except I can use it on my PC so I know that it works fine.
If anyone has any information about how to fix this, or any ideas. Please let me know! I would very much like to get this macbook going again.

The correct format for Mac OS X is not FAT-32.
As the computer shipped with an install-restore disc DVD set that could be used to start the computer as an emergency disc and use the Utilities on the Installer, without running the Installer itself, to format, attempt repair, and perform a few different system installs or reinstalls, this is where the correct format would come from.
Was there documentation to confirm the build year and model information, such as to refer you to the product page link you posted above?
If accurate, that MacBook shipped with this custom grey
install-restore DVD version of Snow Leopard:
Original OS
Mac OS X 10.6.1 (10A2047)
Maximum OS
Latest release of OS X
AirDrop
Supported
Hardware Test
AHT 3A181
And to be able to restore the basic OS X to that level, official replacement discs for that computer should be ordered from AppleCare; to facilitiate obtaining correct ones, you should find the product serial number. There likely would be a fee involved. The replacement disc set may have a different number than the one in the information box above, but would match the hardware series by Apple standards. And a replacement disc may not have the original extra applications that shipped with the computer when new. Those original discs are part of the retail computer, an essential part number, like the power adapter, and should be included with the computer even after an OS X upgrade, since they allow basic access without using the internet.
The remainder of the Snow Leopard 10.6(.8) would be a download Software Update Combo v 10.6.8, either direct from Apple servers or through the computer's running Software Update. Once the computer is up to date in Snow Leopard, 10.6.8, then one could visit the Mac App Store, App Store, and iTunes Store; from the Mac App Store, and you could check/get the latest upgrade to Mac OS X, 10.9.2. An Apple ID is required to access.
The computer may not support Mavericks 10.9.2, or may be able to, but could use an upgrade of RAM capacity.
If your model and build year series info is correct:
Maximum Memory
8.0 GB (Actual) 4.0 GB (Apple)
Memory Slots
2 - 204-pin PC3-8500 (1066MHz) DDR3 SO-DIMM
For more information see the database download http://mactracker.ca
and also compare specs with macbook models at everymac.com.
The newer OS X systems that can use a Recovery HD partition on the hard disk drive, can start from there to repair their hard disk drive, and reformat the section where the Mac OS X runs, and reinstall that. Since there is no likelihood of that still being on the drive once it was FAT-32 reformatted, it will not be present to assist in attempts to reformat the drive; if the computer had been upgraded past Snow Leopard 10.6, to a later system that would have used the recovery partition, or the later internet recovery system. That goes to Apple Servers to use OS X Utilities and reinstall the system, helpful for computers without optical drives or system media. Your MacBook with 10.6.8 installed, then had to access the Mac App Store, to get 10.7.5, 10.8.5, or 10.9.x
Identify your Mac lookup by model number or serial number:
https://www.powerbookmedic.com/identify-mac-serial.php
Anyway, the hardware in the computer may need some inspection, troubleshooting, and maybe repair; but the original DVD install-restore disc has an Apple Hardware Test on it, for that series build model macbook. That could help in troubleshooting some aspects of the computer. Could be the hard disk drive failed; or if someone tried to upgrade the RAM, the system may not have worked correctly. Hard to say how it was messed up, at this stage. There are several possible causes.
Hopefully you can get the correct disc set from AppleCare.
You can call Support number, or use Contact Support page.
Good luck & happy computing!

Won't boot from install discs after deleting some system files

I've been looking through the forum and haven't found an answer to my problem - maybe someone can help me out.
I have an aluminum Powerbook G4, 1.67, 1.5 RAM, 10.4.11. I was experiencing the problem with FCE capturing video for about 5 minutes and then freezing, and I read some threads here about how this can be fixed by returning to Quicktime 7.2 and installing it with Pacifist. I did this, but first tried to delete my previous Quicktime version files, and obviously I deleted some system files in the process. That's how my new problem started.
Programs now that do not open - Preview, iTunes, iMovie, FCE, Yahoo, Mail, and Microsoft Messenger. I no longer have my date/time/battery level/airport/bluetooth indicators in my toolbar. The Spotlight icon flashes, but will not open. Also, when opening the System Preferences pane, it opens just for a second or two and then crashes and closes. Safari, airport, and Word all work, though, and I still can access internet.
I tried to re-install OS 10.4 from my black install disc. The computer reads the disc, but after I click the installer icon and then "restart," the computer fails to completely reboot. The disc spins in the drive, I get the Apple, the indicator, and then the screen goes to blue and the disc soon stops spinning. Nothing happens after that. I've tried rebooting by holding down the C key but the same happens. When I hold down the option key, I get to the point where I can choose to boot from the install disc, and then the same thing happens - the blue screen and nothing more. Booting with the shift key held down doesn't work either.
I did just have a repair by Apple - my adaptor plug sparked when inserting it into the outlet, and I had to have the logic board replaced. But the computer seemed to be working fine when I got it back, except for the FCE issue first mentioned. Looks like my good intentions have done me in.
The install disc is about three years old, and is in good condition. It's been in the garage, so could heat or cold affect the readability of the disc?
Does anyone have any suggestions on how I can boot from my install disc and get a fresh install of my OS?

Hi bboross,
Tough without a Tiger Disk, but try fsck...
To use fsck, you must run it from the command line. Unlike using your mouse to open an application to do something, you'll need to type a text command at the prompt (#) to tell fsck what to do. The Terminal application (/Applications/Utilities) and single-user mode are two examples of command-line interfaces in which you can type such commands. To use fsck:
1. Start up your computer in single-user mode to reach the command line. Hold CMD+s keys down at bootup. Note: If necessary, perform a forced restart as described in the Emergency Troubleshooting Handbook that came with your computer. On desktop computers, you can do this by pressing the reset/interrupt button (if there is one) or holding down the power button for several seconds. On portable computers, simultaneously press the Command-Control-power keys. If your portable computer doesn't restart with this method, you may need to reset the Power Manager.
2. At the command-line prompt, type /sbin/fsck -fy
(space between fsck and -fy important)
3. Press Return. fsck will go through five "phases" and then return information about your disk's use and fragmentation. Once it finishes, it'll display this message if no issue is found: ** The volume (nameofvolume) appears to be OK  If fsck found issues and has altered, repaired, or fixed anything, it will display this message: *** FILE SYSTEM WAS MODIFIED ***   Important: If this message appears, repeat the fsck command you typed in step 2 until fsck tells you that your volume appears to be OK (first-pass repairs may uncover additional issues, so this is a normal thing to do).
4. When fsck reports that your volume is OK, type reboot at the prompt and then press Return.
http://docs.info.apple.com/article.html?artnum=106214
Then Safe Boot , (holding Shift key down at bootup), & use Disk Utility from there to Repair Permissions, reboot once more.

Hyper-V 2012 R2 Gen 2 VM failed to boot from SCSI DVD drive using ISO image file

Hello:
I'm having a problem trying to install Windows 8.1 Professional on a new Gen 2 VM. I created a new Gen 2 VM using Hyper-V Manager running on Windows Server 2012 R2 and then told it to boot off DVD drive which pionts to the ISO file that I copied to the E:
drive. The ISO file mounted in the virtual DVD drive is the Windows 8.1 Professional x64 VL ISO that I downloaded off of TechNet. When I start up the VM to install the OS, I receive this error:
"Synthetic SCSI Controller (Instance ID 7512B228-F7BC-4DD8-B4F4-72A5B042C2E9): Failed to Power on with Error 'The file or directory is corrupted and unreadable.' (0x80070570). (Virtual machine ID 4195A398-3531-4A34-8588-D1FC3F3DD2D4)"
Basically the SCSI controller can't read the ISO file. However, the IDE controller on a Gen1 VM can read and boot from the ISO just fine. Has anyone else run into this problem? Is there a way to resolve this issue and allow me to boot the ISO from a SCSI
controller?
Or is there a bug with the Hyper-V SCSI controller that makes it unable to boot from ISOs properly?
-JP

Hi JP,
In addition , please try :
1. copy the ISO to an not shared local folder or drive
2. uncheck the "enable secure boot" in VM settings .
If the issue still persists , maybe you can try to down load a new ISO file then try to boot again .
Hope it helps

I'd like to carry my system, applications and files on a portable Thunderbolt ssd drive and boot from it. I have a Mac Pro in the office, iMac at home

I'd like to carry my system, applications and files on a portable Thunderbolt ssd drive and boot from it. I have a Mac Pro in the office, iMac at home, a MacBook Air for when I'm on the road, all with TB. Can a single external TB drive boot all three hardware configurations successfully? I've been told that differences in hardware configurations between the systems make this impossible. Is this correct?

Piece or peace of cake really though.
A quick install on new hard drive or SSD or 10K and less than an hour to move everything over properly.
YOU looked for a quick fix and found none and all the brick walls.
It is not days of work to do a clean install and migrate.
There are few if any apps that need to be freshly installed either though there are updates needed for them to be compliant, any driver or plugin also and that is done ahead of time with research.
And your backup or clone of your system is taken care of - you leave the old system boot drive 'as is' untouched.
Also, better strategy to move most all your home folder (except for its own ~/Library) to ANOTHER disk drive and not on t he system drive at all.
As for applications on its own drive or 3rd party, beeen there done that, even SSD or 15K SCSI - no benefit in performance or organization.

Disk repair failed how can I back up my files when I can't boot from the start up disk

When disk repair fails, and I can't boot from the hard drive how can I get to my files to back them up. I have a seagate 1 TB connected to the USB port.

SG300-28 How update boot from file rfb - version 1.3.5.06

I download to my switch SG300-28 new firmware version 1.3.5.58 I package zip i found two file:
sx300_fw-13558.ros - this is the firmware
sx300_boot-13506.rfb this is the boot code
I upgrade firmware by WEBGUI swicth. ADMINISTRATION>FILE MANAGEMENT>UPGRADE/BACKUP FIRMWARE/LANGUAGE
But i dont know how i can upgrade BOOT from WEBGUI or other... Please help me a tell my how-step by step.

Hello.-
After reading release notes and some experiences in this forum, I am really worried about upgrading a SG300 firmware 1.1.2.0 to version 1.3.5.58. Release Notes points out that you have to update the boot loader before the firmware. However some users report that they had to reconfigure the switche after the upgrade.
My concern are.
- Is it necesary to boot the switche after upgrading the boot loader ?. This is not going to be a problem with the old firmware?.
- Can I apply the confirguration backup after the firmware upgrade or is necesary to reset to factory default and do it from scratch ?.
Thanks.

Seperate out User related files from Syste related files for boot disc

I have a primary drive with the default Mac set up of System files, Application files and User files.
I want to end up with the System files, Application folder etc but not the User folder directory on a standalone drive that I can boot from.
I have copied the System related files (not the user files) to a new drive. However the drive containing the system files is not recognisable as a boot drive.
Is it possible to make it a boot drive.
The ultimate aim is to set up a SSD drive for the System and programs without having to do a major re install of the OS and applications.

Copy everything under /Users to another drive.
You can use CCC to do that or you can do it manually.
Clone everything but user account folders. Make sure you have a bootable system. Some rerun Combo update as part of refresh when moving the system.
Actually clean install of OS X takes minutes, and Setup Assistant will ask what you want to import off your WORKING system.
Leave a small user folder ~/Library and empty all the other files on your system drive.
Keep your default drive as is for a week to serve as backup.
