No eth0 device required to activate Matlab software
So, MathWorks requires a local Host-ID in order to use their Matlab software. According to their docs this is how you find the Host-ID, but such steps did not work for me.
https://www.mathworks.com/support/activ … ogethostid
Also, when I attempt to start Matlab with a license file using what I thought to be the correct Host-ID I just get this error:
License checkout failed.
License Manager Error -9
The hostid of your computer (000000000000) does not match the hostid of the license file
(0024be323423).
Troubleshoot this issue by visiting:
http://www.mathworks.com/support/lme/R2012a/9
Diagnostic Information:
Feature: SR_MATLAB
License path: /home/branden/.matlab/R2012a_licenses:/home/branden/Programs/matlab/licenses/license.dat:/home/brand
en/Programs/matlab/licenses/license.lic
Licensing error: -9,57.
Which says my Host-ID is all zeros?
If I attempt and use the Matlab Installer's automatic activation it will fail for this very reason (Host-ID being found as 000000000000).
Error -2,007: Unable to activate your machine. The activation process cannot detect a
valid Host ID which utilizes a currently supported naming convention. Please refer to the
following solution ID, to help resolve this issue: 1-661QJD
I think this problem has to do with not actually having any "eth0" that is expected by matlab according to:
http://www.mathworks.com/matlabcentral/ … th0-device
For instance:
[branden@localhost net]$ ls /sys/class/net/
enp8s0 lo wlp6s0

This is what you seek if you want an eth0: https://wiki.archlinux.org/index.php/Ne … Interfaces
Or crack open the thing that generates the Host ID (assuming it's not compiled) and replace eth0 with (probably) enp0s23 or whatever you NIC name is.
I saw that in my research but was worried that actually changing the name of the device would cause other cascading issues. Will this be the case?
Also, being quite new to Arch Linux, I do not have anything in /etc/udev/rules.d/
Do I just create the file 10-network.rules from the link you posted?
This solution worked perfectly.

My problem I worked updated iPhone 3 gs (ios4) to version (ios6), and when operating the device required to activate the phone and therefore appears to me aftermarket says (IMEI 01 216 300 555 018 3 ) ICCCID unknown.
There is no network
I hope that I showed you my problemThat's a critical failure. It can not be fixed. It is usually the result of jailbreaking or hacking the phone to unlock it.

Create persistent dummy eth0 device
I run the proprietary MATLAB software which checks a license file against the mac address of eth0 in an attempt to prevent piracy. The switch to consistent network device naming means I no longer have a eth0 network adapter. Piecing together information I have gather from various forums has lead me to
modprobe dummy
ip l set dev dummy0 name eth0
ip link set dev eth0 address xx:xx:xx:xx:xx:xx
I guess the first question is, is this the best way to do it in Arch? The second question is how do I make this persistent across reboots? I understand how to load the module (I think): I am planning on creating a file in /etc/modules-load.d/dummy.conf with the contents dummy to take care of the module loading. To set the name would it be reasonable to do create something like /etc/systemd/system/dummy.service
[Unit]
Description=Create dummy network interface
[Service]
Type=oneshot
ExecStart=/usr/sbin/ip l set dev dummy0 name eth0
ExecStart=/usr/sbin/ip link set dev eth0 address xx:xx:xx:xx:xx:xx
RemainAfterExit=yes
[Install]
WantedBy=multi-user.target
Note I stole the above from https://wiki.archlinux.org/index.php/Sy … cuous_mode and do not understand the RemainAfterExit and WantedBy parts ...
How do I make sure this waits for the dummy kernel module to finish loading?
Last edited by daniel_shub (2013-04-29 18:44:16)Does predictable net naming actually benefit you? If you're only using one network device, the answer is no, and you can quite safely turn it off. Creating a dummy interface for one dumb piece of proprietary software is a lot sillier IMO.

'Remote' app requirements are stated as "software version 3.1.3 or later". I am running 4.2.1 and when I try to download it says 4.3 required.
OK, I understand that new versions make use of facilities that come with new versions of IOS, but there is/was a version that runs on 3.1.3 and therefore, I assume 4.2.1. Where can I get the (old) version that runs on my IOS?
The app store seems to ignore all legacy equipment owners, and want me to spend loadsa money to get the latest shiny toy. It probably makes business sense, but I dislike companies that take that approach. This is my first venture into smart phones, and I like the IOS interface, but I'm not sure I can afford the maintenance.The app store seems to ignore all legacy equipment owners, and want me to spend loadsa money to get the latest shiny toy. It probably makes business sense, but I dislike companies that take that approach.
This is standard for Apple. While there is little official mention of the software support lifespan for equipment, typical support has been about 4-5 years for computers. It strikes me that newer items, especially mobile devices, are not built as sturdily nor do they have the hardware upgrade capabilities required to keep up with newer systems. When we bought an iPhone 4S we were told by the person in the store we'd probably be looking at a newer model in two years. The iPhone 3G could be anywhere from 2 to 4 years old, putting it well into.
As for app availability, Apple typically pulls old software versions from its site when new versions appear. If it is a non-Apple app then I guess it is up to the vendor. It is indeed tiresome but it is not at all unusual. Since I only ever run used Macs, I download current versions even though my computer won't run them, stick them on a hard drive, then I have them when I upgrade to a newer used computer. If you run older equipment you have to learn a different mode of operation to exist with the Apple 'new and innovative' but 'forget about the old' philosophy. -
I tried to export photos from iMac to iPad using a USB flash drive. The photos are on the drive but when I plug it into the iPad, the iPad says the device requires too much power. Any ideas of what type of USB flash drive I should use?
You can transfer photos outside of iTunes. I do it all the time. THat said, i have a 50/50 success rate with them. I'd avoid sandisk and kingston, their bundled software triggers the 'too much power' warning.
I've had mixed luck with lexar, some work, some don't.
I did have good luck with an older 4 gig geek squad one.
Look for drives without software on them, without bright LED lights and I haven't gotten any larger than 4 gig to work, but that may just be me.
For a less troublesome way? h onestly, I use a SD card that I've formatted with the DCIM folder. I've never had one of them trigger the 'too much power' warning. Just make sure they're not SDXC. those don't work. -

IPad Air - The connected device requires too much power.
When connecting my iDJ Live II to my new iPad Air I receive the following message:
Cannot Use Device
Numark iDJ Live II: The connected device requires too much power.
The iPad Air is running iOS 7.0.4, I also have an iPhone 5S, iPad Mini and iPad 2 all running latest iOS 7.0.4 and this dj controller runs on all these models. I know about the 20mA output limit on these other devices but they all still work why not the iPad Air? What has changed?
I am very disappointed with this restriction as the only reason I bought the iPad Air was for the better processing power and 128gb storage to fit all my music on there to use this dj controller with djay 2 and vjay. Now I have spent $900 on something I can not use as intended.
Please any help would be appreciated.
Thanks
AdamTry giving your iPad a reset. See if it can clear up the error or if it repeats. Hold down the sleep and home keys until it reboots then try again.
How does this device plug in? Via the lightning connector or the USB part of the camera kit? If it's USB then sometimes a powered USB hub can help with the power issues.
If it's lightning then the issue could be related to something that came with iOS7. Due to so many unauthorized lightning cables, iOS7 activated software that looks for a code broadcast by the chip in the lightning connector. Authorized manufacturers have codes that the software sees, unauthorized ones don't. Usually people using unauthorized cables get a specific message, however it could be possible that this new part of the software is affecting other things connected to the lightning port.
Have you looked on djay's site to see if others are having issues or if they have fixes? -
you are running the latest version of iTunes, have no other USB devices attached, have no security software installed, and are directly connected to your ISP source, simply restarting the computer and the iOS device can clear up certain issues that could prevent you from restoring. After restarting the computer and iOS device, attempt to restore again.
How big is your library? I would recommend the following troubleshooting steps:
- Backup your library. Always a good idea before messing with things.
- Create a new library. Refer to this article for details: http://support.apple.com/kb/HT1589. This won't delete your old library, you're just creating a new empty one. Also refer to this article to get back to your old library later.
- Add a few albums into this new library. Not everything, just a small sampling, as a test.
- Activate Match on this new library. You shouldn't have to re-pay, it should just say "Add Computer" or similar.
- At this point, Match should run again. With just a few albums it should complete in just a few minutes.
If iTunes doesn't crash at this point, then likely there's something about your original library that Match doesn't like - what that is I don't know, but at least you'll know it's not your PC. If iTunes still crashes, then if could be a number of other things, but probably not your library. My next suggestion (if you haven't already done this) is to uninstall / reinstall iTunes. If that doesn't work, then my next ideas you won't like. -
Required to Activate iPad After Rebooting
Has anyone recently rebooted their iPad, then have a request to enter Apple ID and password to reactivate iPad? I received the following message prior to the passcode screen:
"Activate iPad. This iPad is currently linked to an Apple ID (my Apple ID abbreviated). Sign in with the Apple ID that was used to set up this iPad." Spaces for Apple ID and Password were provided. Then a link to "Activation Help" was given, which I clicked. It said:
"A password is required to activate this device because its owner has used Find My iPhone to link it to their Apple ID.
If this is your device, enter the Apple ID and password you used to set up iCloud.
If you were given this device or purchased it second-hand, you will need to contact the original owner to have them remove this device from their account. Additional information can be found at: support.apple.com/kb/TS4515."
I went to this website on my PC . . . no such website exists.
I sense this is a malware attack to shake me down for money to unlock my device. Has anyone else had this happen? I'm planning to go to the local Apple Store this afternoon for advice.
Thanks.The page does exist, it's just that it's now been renamed (that's the original name, Apple have been renaming their troubleshooting and help pages) : Find My iPhone Activation Lock: Removing a device from a previous owner’s account - Apple Support (my browser redirects me to the new page from http://support.apple.com/kb/TS4515 ).
What do you mean by 'rebooted' your iPad ? If you reset it back to factory defaults, or restored to a backup, then you will see the activation lock screen asking for the id and password that you were using in Settings > iCloud on the iPad (and if you had Find My iPad enabled), it's a theft deterrent. If you type in your id and password the iPad should reactivate.

Requirements to activate an iPhone 4S
When the iPhone 5S came out, a family member upgraded from a 4S to a 5S. At least, I think that's what happened. Anyway, what I remember was they went to the AT&T or Apple store to pickup the new phone. Took it home, migrate to the new phone. When they wiped the old iPhone 4S and upgraded the software (I think it's still running iOS 6), it was stuck not being able to activate.
My brother took it to the Apple store, who proceeded to say it was broken, but was eligible for $$ in a a trade-in to buy a new 5S. They said the phone must not be communicating with he Apple servers.
This was over a year ago now. And I want to get this to one of our kids. Does a 4S require an activate sim card to be able to activate? If I perform the AT&T unlock process, will it activate without any sim or with an inactive AT&T sim?In iTunes it gives the error:
Your request couldn’t be processed.
We’re sorry, but there was an error processing your request. Please try again later.
On the iPhone doing activation over WiFi, it says:
Could not activate phone
Your iPhone could not be activated because the activation server is temporarily unavailable. Try connecting your iPhone to iTunes to activate it, or try again in a couple of minutes. -
My PC serves the minimum requirements described in the kinect page, but when installing the device, the software says that the computer does not meet the minimum requirements and therefore will not work with efficiency. Alternatively, theorize buy a new
computer.
Which PC is recommended by Microsoft that ACTUALLY meet the requirements to work with software development for kinect for windows?Getting a definitive answer from Microsoft will be difficult as to my understanding, requirements are still subject to change; and unless it's their brand of PC I doubt they will give free advertisement to buy a specific make/model.
There are other threads where people discuss specific machines that work with the Kinect V2.
The only compatibility problems I've had with getting it to work are: It has to be run Windows 8; It has to have a compatible USB 3.0; The 'Compatible' USB 3.0 requirement seems to be the most difficult. -

From within Photoshop Elements, when I try to open Editor, a box opens that states I must activate the software. I registered and activated the software last year. When I click to activate, I get a message that I am not connected to the internet. I am connected. How do I get Editor to work?
You would get the redemption code, or perhaps even the serial number, from whomever you purchased the software from, apparently Amazon, so talk to them. This wouldn’t be the first time they’ve sold something that didn’t have all the numbers needed to license it.
A redemption code is something that is usually on the inner disc packaging if you purchase the media in a box, and there is a barcode on the outside of the packaging that must be scanned at the checkout register to activate the hidden inner code so you can redeem it at home on that website. This is what happens if you buy PSE from a brick-and-mortar store like Best Buy. I don’t’ know what happens if you purchase the downloaded version as I have never done that.
A redemption code is 24-digits of letters and numbers that you enter into a website to get a serial number, once and only once. The serial number of only 24-digits, no letters, is what you enter into the software during the install or when you run it and it asks if you want to register or run in a trial mode—whatever the exact phrasing is.
In any case it sounds like you don’t have either a redemption code or serial number—although perhaps something is listed on the purchase confirmation or your account online at Amazon or even in an e-mail from Amazon. -
