Netbooting and NetInstalling Problems
Hello All!
I have a problem, I have created an image off of a known to be working (I am using it now) install from my personal computer to boot off of for computer problems. But, when testing it out my computer would startup, display the rotating globe, then, where the apple is going to come up, a large black box appears and the progress wheel freezes.
I tried a NetInstall off of the Tiger Install disc and when booting off of it, the computer does the rotating globe, the apple appears then the computer completely shuts down.
How did you create the image? And as with any other service, DNS needs to be configured correctly for Netboot/Netinstall to function reliably.

Lion NetBoot and NetInstall causing kernel panic
I'm trying to get NetBoot and NetInstall working on a recently set up a new Mac Mini with OS X Lion Server.
We previously had Snow Leopard server and moved the existing images onto the Lion Server. However, when trying to boot off either image the machines kernel panic.
Have tried creating new images, but with the same result.
Anyone with similar issues who have managed to fix it?Thanks for your reply. I will try what you suggest and also read through the troubleshooting tips you linked to. Cheers!
I do have have some furher information about the problem.
Definitely some strange behaviour here - I'll try to explain is as well as I can.
Started out activating one NetInstall image of Lion 10.7.2 (did not have 10.7.3 on hand). When testing with my MacBook Pro (17-inch, Mid 2009) currently runing Lion (came with Snow Leopard), I got a kernel panic. However, when choosing the NetInstall image as startup disk via System Prefrences, it boots up fine via this image.
After a while I also added a Snow Leopard NetInstall image (newly created on one of our machines still running Snow Leopard). With the Lion set to be the default netboot image. When booting my machine into startup manager, then pressing 'N' to see netboot images, I only get one additional icon (despite there being two enabled images) with the server IP underneath. When selecting that icon, the machine boots up with the Snow Leopard installer (despite Lion being set as the default).
Trying the same with an iMac without a hard drive, this iMac would have come with Snow Leopard preinstalled, shows me both NetInstall images in startup manager, but I get a kernel panic when trying to boot off the Snow Leopard image - not the Lion image. Selecting the Lion image as startup disk while booted from the SL image results in a successful boot from the Lion image.
To recap:
On MacBook Pro
Startup manager, Lion boot = kernel panic
Startup manager, SL boot = success
Startup disk chooser, Lion boot = success
Startup disk chooser, SL boot = success
On iMac
Startup manager, Lion boot = success
Startup manager, SL boot = kernel panic
Startup disk chooser, Lion boot = success
Startup disk chooser, SL boot = success
The above is true when sharing the images both over NFS and HTTP. -
10.5 Server hosting 10.4 netboot and netinstall images
It appears that 10.5 Server can only host 10.5 netboot and netinstall images, at least according to the documentation that accompanies System Image Utility. Does anyone know of a workaround? I have 10.5 Server on our office Xserve, but only have one 10.5 client and most of the computers we have can't run 10.5 anyway. I had a 10.4.x netinstall image and netboot image set up under 10.4 Server that worked beautifully, but apparently Apple seems to want to FORCE people to upgrade, which really angers me.
Does anyone know a workaround that would allow me to continue using a 10.4 netinstall image and netboot image as hosted by 10.5 Server?I've not tried making any new images with the System Image Util yet but our old 10.4 images stayed on the server when I upgraded it from 10.4 to 10.5 and the images still work.
Did you upgrade the NetBoot server from 10.4 or did you do a clean install? I just had to uncheck the images and check them again and restart NetBoot!
Luckily we're about to go up to 10.5 on all the machines here! -
Netinstall Problem - clients cannot see boot image
Hi all,
I really want to be more efficient at deploying images out to the more than 100 Macs I am in charge of in my job. So, I've been researching all my options, and finally decided to just jump in and build an image to deploy!
I was pleasantly surprised at how easy instaDMG was to work with, and though I don't expect it to go smoothly, would really like to try out deploying my image to a machine for the first time. I realize that I can't do this until I boot said machine from an alternate OS source than the one that runs the hard drive of the Mac. So, I attempted and somewhat successfully created a netinstall image.
I have been unable to boot the Mac on my network that I want to try deploying to from the netinstall image I created and put on my server. I have researched and tried everything I can find, but I am totally at a loss now about how to make this Mac recognize on bootup that there is something for it to grab on the network. All I get is the flashing world at start up, and then after a few minutes of that it gives up and boots from its hard drive.
Please help me! How can I make this thing work?
Here is what I have tried:
I created the netinstall image and placed it in the /Library/NetBoot/NetBootSP0 folder that was created when I activated a NetBoot server.
I set up the NetBoot and NetBoot Client sharepoints for access, and even created an additional new user called "image" (nonadministrative) for later authentication.
I also tried telling these two sharepoints to automount, thinking maybe that was the problem.
It is entirely possible that some of the settings I chose to use during set up of any of these things were wrong, though I tried to follow instructions I had from numerous places as carefully as I could. The problem is, I am not a networking person, and really am a biologist by trade - the computer stuff is an aside, and a self-taught sort of thing.
Can someone help me trouble shoot my issue here?
Thanks much in advance!Hi
+"Could that be the problem? If so, how do I fix it?"+
Apart from the advice Brian has offered you should be aware of some general information regarding the Service itself. The Service does not work wirelessly. There needs to be a DHCP Service running somewhere on the same network. Clients 'discover' the Service using DHCP, BDSP, BootP and TFTP. The DHCP Service does not have to be on the Server itself. Netboot does not traverse subnets easily. If you don't have the facility to traverse subnets (ie: switches capable of providing an IP Helper address for the NetBoot Server itself) then you will need to either (a) place a NetBoot Server at each subnet or (b) use Routers or VLANS to route/relay appropriate traffic for each subnet.
+"You mention an IP Helper. Is this something in my server software that I have already?"+
No
+"Or an additional downloaded program?"+
No
An IP Helper Address is configured in your switch (if capable) as already mentioned. You could approach this another way? Configure the DHCP Service to hand out IP addresses to your mac clients that are within the same subnet as your NetBoot Server. Or you could look at it another way and re-assign your NetBoot Server's IP Address to be one that is part of the same range as your clients. Obviously it needs to be an address that is not within the Clients' DHCP Pool.

Explains what an IP Helper Address is.

NetBoot and Multiple DHCP Servers
Hey everyone,
We have a NetBoot machine running here at my school (where I work). It was working like a champ until a couple of weeks ago when our network got upgraded and there are now 2 DHCP servers on our network. That, for some reason, is totally screwing up our NetBooting process.
Here's what I think is happening, and maybe someone can tell me if I right or wrong. NetBoot (or BSDP protocol) is a "broadcast" protocol. (That means it's always just floating around out there on the network. ) NetBoot (BSDP) protocol gets injected into the DHCP stream, and any machine that gets DHCP can get BSDP, and essentially NetBoot.
The problem is with BSDP. BSDP protocol wants to have all of it's "broadcasts" come from the same server. So when we had 1 DHCP server, everything was fine, because client machines would get their whole NetBoot process from one machine... all of the BSDP broadcasts were coming from our 1 DHCP server.
Now, we have 2 DHCP servers. What happens is, a client will get some of it's BSDP broadcasts from one DHCP server, and some from another... which it does not like at all.
I recently read somewhere that it is possible to somehow make one of our DHCP servers the "authoritative" server, to which all of the clients will go to get their NetBooting info.
Does this sound in any way right? Are we on the right track ? Has anyone seen this before? Any help would be greatly appreciated. Thanks a million.
MikeNow, we have 2 DHCP servers. What happens is, a
a client will get some of it's BSDP broadcasts from
one DHCP server, and some from another... which it
does not like at all.
Not unless your new DHCP server is also a NetBoot server and is set to provide NetBoot services. BSDP and DHCP are not the same thing. If what you were saying were true, it wouldn't be possible to have DHCP and NetBoot offered by different servers.
It IS possible, however, that the two DHCP servers are causing problems by both servicing DHCP requests for the same clients. If you've got multiple DHCP servers on the same subnet (or your router's configured to pass DHCP requests between subnets), you should make sure that only one of the DHCP servers answers requests from any given client. In our world, our Novell server is the default DHCP server on our subnet, but I keep a list of excluded MAC addresses on that server so that my Macintosh clients don't get addresses from it. On the Mac OS X server, I'm careful to limit my address ranges only to those machines which have static address maps in NetInfo. That way, our servers coexist, but they don't overlap.
It's not clear from your message whether your previously solitary DHCP server was your Mac OS X server, or whether one of the two DHCP servers is that box. But whatever the servers are, it might be helpful to turn off one of them to see if the same problem occurs (assuming you can, without major network disruptions). If that's not possible, can you talk to your network admins to see if there's some way to isolate your clients and one of the servers--in other words, see if there's some way to keep DHCP servers from responding to the same requests.
There may be any number of other reasons why this problem has cropped up. You may need to dust off a hub and a copy of Ethereal or EtherPeek to sniff what's happening on the network. You might also try NetBooting in verbose mode, to see where the process craps out. IIRC, there'a decent guide for this kind of troubleshooting over at Bombich's site (www.bombich.com).
Good luck.

Greetings,
I set up NetBoot on a 10.6 mini server with the intention of using the feature to image clients as well as to use diskutil for disk diagnostic and repair.
I have no trouble booting into my NetBoot image. However, when I attempt to image the booted client's internal HD, I am unable to get the HD to unmount. If I force an unmount then the applications on the NetBoot image will not function correctly. It would seem that there is a lock on the internal volume. Dragging it to the trash or doing an unmountDisk yields a disk in use error.
I am wondering if perhaps I have a corrupted shadow file, or otherwise perhaps I should re-create my boot image?
Thanks for anything you care to offer.********* SOLVED *********
First I would like to thank everybody who thought about this issue. I see a lot of you were looking at it. You may have recently noticed some latency on your internet connection. That was me searching for an answer!
OK, here it is:
Launch your "Server Admin" utility.
Select your Server Name below "Available Servers" in the left hand column.
Select the "Access" icon at the top of the window.
Select the "for selected services below:" radio button on top of the list of services.
Select "AFP" in the services list.
Make sure the *Allow all users and groups* radio button is selected under the "Services" tab.
Click the "Save" button.
The problem I experienced was caused by that setting *Allow all users and groups*, being set to "Allow only users and groups below", which was currently unpopulated, empty.
That former setting caused the "Diskless" NetBoot setting to fail, as the afp share hosting the shadow file on the server failed to mount on the NetBooted client, resulting in the afp error: "SACL membership failure for user netboot101". The local disk was therefore unable to be unmounted and the shadow file was forced to be hosted on the local disk, rather than the afp share on the server- which is the normal process for diskless NetBooting.
You could most likely populate a group in there and change the setting back, but for the time being I am happy that I am now able to NetBoot and Image a NetBooted computer. -
I need to set up a Netboot server on the same network as an MS Windows Deployment Services(WDS).
The problem is we only have one DHCP server. I wanted to know if I assign a static IP to one of the NICs on the xserver to a different IP subent could I point the Mac machines to that netboot server with out DHCP. I have never setup a netboot server so I don't fully understand how it works. My understanding is Mac machines will use DHCP to find the netboot server. Any suggestions will help.
The basic problem is I need to run Netboot and WDS on the same physical network. I am open to any suggestions on getting it to work.DHCP needs to be enabled for Netboot to work, but if you disable all the DHCP subnets in "Server Admin > DHCP > Settings," the Mac DHCP service will start and run, but won't actually issue any IP's, and thus shouldn't interfere with your 3rd party DHCP server.

Question
I am not able to launch FF everytime i try to open it, it says FF has to submit a crash report,and restore yr tabs. I even tried doing that and the report was submitted too, but still FF did not start, and the problem still persists, please help me solve this issue
'''(in English)'''Hi Danny,
Per my understanding that you can't get the expect result by using the expression "=Count(Fields!TICKET_STATUS.Value=4) " to count the the TICKET_STATUS which value is 4, the result will returns the count of all the TICKET_STATUS values(206)
but not 180, right?
I have tested on my local environment and can reproduce the issue, the issue caused by you are using the count() function in the incorrect way, please modify the expression as below and have a test:
=COUNT(IIF(Fields!TICKET_STATUS.Value=4 ,1,Nothing))
or
=SUM(IIF(Fields!TICKET_STATUS=4,1,0))
If you still have any problem, please feel free to ask.

BOSD, Battery issues and Heating problem after iOS 8 upgrade
i have upgraded my iPad mini to iOS 8. Ever since I upgraded to iOS 8 am facing blue screen issues and heating problem as well. This is really frustrating even the patch iOS 8.0.2 dint solve the problem. Are you guys listening our complaints. When will you fixing it.
The same thing happened to me on my 2012 Subaru Outback. I'm not sure this will help you since you have a Honda, but I'm posting this just in case.
I paired the audio on my car with my iPhone 6. However, when I turned the car off and back on again, the iPhone would not pair automatically. I had to manually connect the iPhone with the car. Turns out there are two separate bluetooth pairings on my car: one for phone which allows up to 5 devices and one for audio which allows only one device. So I did the second bluetooth pairing for the phone (had already done the audio), and that fixed it. YMMV -

I am making code to try to make a game and my problem is that my code
will not let it change the hit everytime so im getting the first guy to hit 1 then next hits 8 and so on and always repeats.
Another problem is that I would like it to attack with out me telling it how much times to attack. I am using Object oriented programming.
Here is the code for my objects:

double bD = floor(1.3 + (eS/10) + (aB/80) + ((eS*aB)/640)); // my base damage

done = rint(fH - fA);
System.out.println("You hit" +done);
}Here is the main code that writes what the objects do:
class fight {
public static void main(String[] args) {
self instance1 = new self();
rockCrab instance2 = new rockCrab();
instance2.health = instance2.health - instance1.done;
System.out.println("You hit: " +instance1.done);
System.out.println("rockCrabs health: " + instance2.health);
instance1.health = instance1.health - instance2.done;
System.out.println("RockCrab hit: " +instance2.done);
System.out.println("rockCrabs health: " + instance1.health);
instance2.health = instance2.health - instance1.done;
System.out.println("You hit: " +instance1.done);
System.out.println("rockCrabs health: " + instance2.health);
instance1.health = instance1.health - instance2.done;
System.out.println("RockCrab hit: " +instance2.done);
System.out.println("rockCrabs health: " + instance1.health);
instance2.health = instance2.health - instance1.done;
System.out.println("You hit: " +instance1.done);
System.out.println("rockCrabs health: " + instance2.health);
instance1.health = instance1.health - instance2.done;
System.out.println("RockCrab hit: " +instance2.done);
System.out.println("rockCrabs health: " + instance1.health);
instance2.health = instance2.health - instance1.done;
System.out.println("You hit: " +instance1.done);
System.out.println("rockCrabs health: " + instance2.health);
instance1.health = instance1.health - instance2.done;
System.out.println("RockCrab hit: " +instance2.done);
System.out.println("rockCrabs health: " + instance1.health);
}when the code is run it says something like this:
you hit 1
RockCrabs health is 9
RockCrab hit 7
your health is 38
you hit 1
RockCrabs health is 8
RockCrab hit 7
your health is 31
you hit 1
RockCrabs health is 7
RockCrab hit 7
your health is 24
you hit 1
RockCrabs health is 6
RockCrab hit 7
your health is 17
my point is whatever some one hits it always repeats that
my expected output would have to be something like
you hit 1
RockCrabs health is 9
RockCrab hit 9
your health is 37
you hit 3
RockCrabs health is 6
RockCrab hit 4
your health is 33
you hit 2
RockCrabs health is 4
RockCrab hit 7
your health is 26
you hit 3
RockCrabs health is 1
RockCrab hit 6
your health is 20

A rather odd and annoying problem has recently been occuring on my MBP. A couple days ago my remote (after working without fail for over a year now) suddenly stopped working. Yesterday night and this morning it started working again but after a while it stopped again. I've read dozens of support articles which haven't really helped because there seems to be another problem.
Most articles have stated that there is an option to disable the IR receiver in the "security" window under system preferences. When the IR and remote are not working this option disappears but when they are working the option is present. I have also tried replacing the battery without any result.
I am now thinking that it might have something to do with heat buildup because it is mainly occuring after the laptop has been on for about a half hour, so I am going to try to borrow someone's fan.
If anyone has any suggestions to solve this I would appreciate it if you could help. Thanks!

LG Ally text message and gps problems
hello. ive been with verizon for about 10 years maybe. ive been overall happy with the service and customer service. but the prices should be alot lower.lol. i started out with the motorolas then switched to the lg phones. only problem with the motorola was the speakers. not loud enough. could never hear the phone ring. the lgs usually suffer from the same problem.
i had a few phone problems but nothing like this lg ally. im on my second one and about to be my 3rd one in about 3 months. 1st phone i had every problem under the sun. this phone i am suffering from text message problems and gps problems. i suffer from what everyone else has problems with. the messages wont send. they will eventually lock up. it will show the envelope with the red explanation point ( i think thats the graphic). then usually everytime when i sent a text the texts will close. it will send then bounce back and show up as a draft and i have to resend it and wait for it to go thru. finally the last problem with the texts. when i send a text a phone number from my contacts shows up and freezes on the screen. its in white text with a black background. its the same number every time. it stays on the screen until i restart or pull my battery out.
gps. when i open up google gps that comes with the phone i make sure the gps is on... when the directions are found and the map pops up 9 out of 10 times it just keeps saying searching for gps. the turn by turn never is found. the 1 time it does it takes a good 10 minutes to be found. atleast on my first one ally the gps did work 8 out of 10 times. it just took a good 5-10 minutes for gps to be found and show turn by turn.
anyone else have these problems? where you able to fix them or did you need to get a new phone? the 2.1 update was supposed to fix problems. i think they just made it worse. the ally is supposed to have 2.2 froyo. where is it. is it ever going to get it. i got this phone because i like the lgs and the keyboard. also the sales representative on the phone was giving the lg ally rave reviews. why couldnt he say dont buy this go with a motorola droid. this phone is the biggest junk ever madeI do apologize you are having trouble with your device I looked in our information system on the LG Ally in reguards to issues you are having it states if you have the Free Droid Security anti virus protection application down loaded it will cause the phone to lock up or freeze. Check and make sure you do not have the application on your device. Check you GPS settings and make sure correct. Go to Settings; Location & Security; make sure GPS is on wireless network. If this does not fix issue you can try doing a Master Reset on your device. Make sure your contacts are saved in your G-mail account or through Back Up Assistance.
Master Reset/Soft Reset:
Factory Reset option 1
From the main screen, touch menu tab
Touch Settings
Touch Privacy
Touch Factory Data reset
Touch Reset Phone
Warning: This will erase all data from your phone, including:
Your Google account
System and application data and settings
Downloaded Applications
It will not erase: Current System software and bundled applications; SD Card files, such as music or Photos
Factory Reset option 2 - Warning this will reset device back to original factory settings.
Turn off the phone
Press and hold "home" + "end" + "volume up or down" keys together for a few seconds when the device is power off
Once device displays boot information, release keys.
Soft Reset
Press the Power key.
Touch Power off.
Touch OK.
Press the Power key to power on the device.
or
Remove battery cover, remove battery and reinstall.Also there is a new update for LG Ally it will be the Froyo 2.2 but there is not release date available at this time it will post on your device when available. Hope this Helps. Leslie -
