Is there a way to toggle bluetooth and/or wifi on and off programatically in iOS?

- by Andy W

I am looking for an easy way to toggle both bluetooth and wifi between on and off states on iOS 4.x devices (iPhone and iPad). I am constantly toggling these functions as I move between different locations and usage scenarios, and right now it takes multiple taps and visits to the Settings App. I am looking to create a simple App, that lives on Springboard, that I can just tap and it will turn off the wifi if it's on, and vice versa, then immediately quit. Similarly with an App for toggling bluetooth’s state. I have the developer SDK, and am comfortable in Xcode and with iOS development, so am happy to write the required Xcode to create the App. I am just at a loss as to which API, private or not, has the required functionality to simply toggle the state of these facilities. Because this is scratching a very personal itch, I have no intent to try and sell the App or get it up on the App store, so conforming with App guidelines on API usage is a non-issue. What I don’t want to do is jailbreak the devices, as I want to keep the core software as shipped. Can anyone point me at some sample code or more info on achieving this goal, as my Google-fu is letting me down, and if the information is out there for 4.x devices I just can’t find it.

stop background of iphone webapp from responding to swipes

- by JoeS

I'm making a mobile version of my website, and trying to make it feel as native as possible on the iphone. However, any background areas of the page respond to swiping gestures such that you can shift the page partway off the screen. Specifically, if the user touches and swipes left, for example, the content shifts off the edge of the screen and one can see a gray background 'behind' the page. How can this be prevented? I'd like to have the page itself be 320x480 with scroll-swiping disabled (except on list elements that I choose). I have added the following meta tags to the top of the page: <meta name="viewport" content="width=320; height=480; initial-scale=1.0; maximum-scale=1.0; user-scalable=0;"/> <meta name="apple-mobile-web-app-capable" content="yes" /> <meta name="apple-mobile-web-app-status-bar-style" content="black" /> I've also tried the following as the event handler for the touchstart, touchmove, and touchend events of the body element: function cancelTouchEvent(e) { if (!e) var e = window.event; e.cancelBubble = true; if (e.stopPropagation) e.stopPropagation(); if (e.preventDefault) e.preventDefault(); return false; } It doesn't stop the swiping behavior, but does prevent clicks on all links on the page... Any help is much appreciated. Thanks!

Cannot access Class methods from previous windows form - C#

- by George

I am writing an app, still, where I need to test some devices every minute for 30 minutes. It made sense to use a timer set to kick off every 60 secs and do whats required in the event handler. However, I need the app to wait for the 30 mins until I have finished with the timer since the following code alters the state of the devices I am trying to monitor. I obviously don't want to use any form of loop to do this. I thought of using another windows form, since I also display the progress, which will simply kick off the timer and wait until its complete. The problem I am having with this is that I use a device Class and cant seem to get access to the methods in the device class from the 2nd (3rd actually - see below) windows form. I have an initial windows form where I get input from the user, then call the 2nd windows form where it work out which tests need to be done and which device classes need to be used, and then I want to call the 3rd windows form to handle the timer. I will have up to 6-7 device classes and so wanted to only instantiate them when actually requiring them, from the 2nd form. Should I have put this logic into the 1st windows form (program class ??) ? Would I not still have the problem of not being able to access device class methods from there too ? Anyway, perhaps someone knows of a better way to do the checks every minute without the rest of the code executing (and changing the status of the devices) or how I should be accessing the methods in the app ?? Well that's the problem, I cant get that part of it to work correctly. Here is the definition for the calling form including the device class - namespace NdtStart { public partial class fclsNDTCalib : Form { NDTClass NDT = new NDTClass(); public fclsNDTCalib() (new fclsNDTTicker(NDT)).ShowDialog(); Here is the class def for the called form - namespace NdtStart { public partial class fclsNDTTicker : Form { public fclsNDTTicker() I tried lots but couldn't get the arguments to work.

Cross-Platform Camera API

- by Karim

Hi, I'm now building a video transforming filter that have to transform video frames in real-time. One of the key requirements of the filter is to have high performance to minimize the number of dropped frames during the transform. Another requirement that is of lower priority but also nice to have is to make it cross-platform (both PC's and Mobile devices). The application is built in C++. Now my question is: is there any API that is more portable and has a similar or better performance characteristics than DirectShow? as DirectShow's portability is only limited to Windows-based devices (PCs and Windows Mobile&CE platforms). Also I've notices that for example using HTC's custom camera API has far better performance than what DirectShow offers. If you want to check this, try to build a filter in DirectShow that will multiply each color by 2 and render that in real-time from camera on the screen. Then do the same with HTC's API. There is almost 4-5x performance boost with vendor's specific API. So it'd be very nice if the library used the device-specific implementation of the driver, as performance is critical when doing this transforms on a mobile device (which is about ~500 MHz).

Accept All Cookies via HttpClient

- by Vinay

So this is currently how my app is set up: 1.) Login Activity. 2.) Once logged in, other activities may be fired up that use PHP scripts that require the cookies sent from logging in. I am using one HttpClient across my app to ensure that the same cookies are used, but my problem is that I am getting 2 of the 3 cookies rejected. I do not care about the validity of the cookies, but I do need them to be accepted. I tried setting the CookiePolicy, but that hasn't worked either. This is what logcat is saying: 11-26 10:33:57.613: WARN/ResponseProcessCookies(271): Cookie rejected: "[version: 0] [name: cookie_user_id][value: 1][domain: www.trackallthethings.com][path: trackallthethings][expiry: Sun Nov 25 11:33:00 CST 2012]". Illegal path attribute "trackallthethings". Path of origin: "/mobile-api/login.php" 11-26 10:33:57.593: WARN/ResponseProcessCookies(271): Cookie rejected: "[version: 0][name: cookie_session_id][value: 1985208971][domain: www.trackallthethings.com][path: trackallthethings][expiry: Sun Nov 25 11:33:00 CST 2012]". Illegal path attribute "trackallthethings". Path of origin: "/mobile-api/login.php" I am sure that my actual code is correct (my app still logs in correctly, just doesn't accept the aforementioned cookies), but here it is anyway: HttpGet httpget = new HttpGet(//MY URL); HttpResponse response; response = Main.httpclient.execute(httpget); HttpEntity entity = response.getEntity(); InputStream in = entity.getContent(); BufferedReader reader = new BufferedReader(new InputStreamReader(in)); StringBuilder sb = new StringBuilder(); From here I use the StringBuilder to simply get the String of the response. Nothing fancy. I understand that the reason my cookies are being rejected is because of an "Illegal path attribute" (I am running a script at /mobile-api/login.php whereas the cookie will return with a path of just "/" for trackallthethings), but I would like to accept the cookies anyhow. Is there a way to do this?

"loading" div automatically appended when using cordova (phonegap)

How to reference SMF libraries when deploying on phone 7 (Release)

- by aHaH

Initially, at Visual Studio, I clicked debug instead of release to deploy my app on phone 7 device. No errors, works perfectly fine! Received multitude of errors that mention that some of the libraries don't seem to exist on the mobile phone. For example, extract from the entire list of errors include Warning 10 The referenced component 'Microsoft.SilverlightMediaFramework.Utilities' could not be found. Warning 3 Could not resolve this reference. Could not locate the assembly "Microsoft.SilverlightMediaFramework.Plugins". Check to make sure the assembly exists on disk. If this reference is required by your code, you may get compilation errors. SLARToolKitWinPhoneSample In addition, im also using Slartookit to power up the AR capabilities. Deploying (Release) on the mobile prompts the following errors too. Error 11 The type or namespace name 'SLARToolKit' could not be found (are you missing a using directive or an assembly reference?) What should I do? Will updating the mobile solve this? Do I have to manually install? Or? Thanks

How do I send data between two computers over the internet

- by Johan

I have been struggling with this for the entire day now, I hope somebody can help me with this. My problem is fairly simple: I wish to transfer data (mostly simple commands) from one PC to another over the internet. I have been able to achieve this using sockets in Java when both computers are connected to my home router. I then connected both computers to the internet using two different mobile phones and attempted to transmit the data again. I used the mobile phones as this provides a direct route to the internet and if I use my router I have to set up port forwarding, at least, that is how I understand it. I think the problem lies in the method that I set up the client socket. I used: Socket kkSocket = new Socket(ipAddress, 3333); where ipAddress is the IP address of the computer running the server. I got the IP address by right-clicking on the connection, status, support. Is that the correct IP address to use or where can I obtain the address of the server? Also, is it possible to get a fixed name for my computer that I can use instead of entering the IP address, as this changes every time I connect to the internet using my mobile phone? Alternatively, are there better methods to solving my problem such as using http, and if so, where can I find more information about this? Thanks!

Execute SSH commands on Cisco router. Codeigniter SSH library

- by jomajo

I have a little problem. I'm using Codeigniter with SSH library written by Shuky (https://bitbucket.org/quicktips/codeigniter-ssh2-library/src/a444968345ba/SSH.php -- You can see the code by following this link). Everything related with SSH works fine with other devices, but when I try to use this library and execute commands on Cisco devices, nothing happens (commands are not executed). I know that the connection is successful, but I can't execute any commands. When I try to run and execute comands through SSH on Cisco devices I get this error: A PHP Error was encountered Severity: Warning Message: stream_set_blocking() expects parameter 1 to be resource, boolean given Filename: libraries/SSH.php Line Number: 128 A PHP Error was encountered Severity: Warning Message: fread() expects parameter 1 to be resource, boolean given Filename: libraries/SSH.php Line Number: 129 In the library these lines look like this: /** * Get stream data * * @access privte * @return bool */ function _get_stream_data($stream) { stream_set_blocking( $stream, true ); while( $buf = fread($stream,4096) ) { $this->data .= $buf.'~'; } return TRUE; } line 128 - stream_set_blocking( $stream, true ); line 129 - while( $buf = fread($stream,4096) ) { Maybe you guys know where the problem is? Thank you for your time and your answers!

Strategies for Synchronizing Data Between a Rails App and iPhone App

- by jessecurry

I've written many iPhone Applications that have pulled data from web services and I've worked on synchronizing data between an iPhone App and a Web Application, but I've always felt that there is probably a better way to handle the synchronization. I'd like to know what strategies you have used to synchronize data between your iPhone(read: mobile) Apps and your Rails(read: web) Applications. Are there any strategies that scale particularly well? How have you dealt with large amounts of data? (Do you use paged responses?) How do you make sure that data is not overwritten? Is there a reason to avoid Ruby on Rails? if so, can you suggest an alternative? What is better about the alternative? What strategies have failed? Why do you believe that those strategies failed? I would like to be able to keep all of the data modifications on the server, but the particular application I am about to start work on will need the ability to operate while disconnected from the network. The user will be able to update data on the mobile device and update data through the web application. When the user's mobile device connects to the server any local changes will be pushed to the server.

- by Blue42

I'm trying to get my android phone working to run apps from inside an IDE. Got it working on windows no problem, currently working in fedora (18) a lot though so wanted to get it working with that. Got IntelliJ and android sdk installed, problem is when I try to run the default hello world app it wont work it just says waiting for device.. Ran adb devices got List of devices attached ???????????? no permissions Leads me to believe the driver isn't installed? Phone I'm using is a HTC Sensation. Does anyone know what I can do to try and resolve it? The HTC web page doesn't offer me drivers to install. Also noticed in /etc/udev/rules.d/..android.rules there is nothing about Sensation. Seems it recognises my nexus 7 though.. Edit: Tried my nexus.. got List of devices attached 901839238298923 offline So it doesn't even work with that.. confusing.. Any help would be appreciated.

problem linking vba modules in MS Access 2007

- by Ted

I am upgrading a database system from Access 2000 db to Access 2007, which communicates with several chemistry measuring devices(pH meter, scale, etc) via an RS 232 serial port. The first db consists of several modules containing vba code that enables the communications with the ports, as well as supports the code behind the forms in the second db. The user, or lab tech, navigates through the forms in the second db to interact with the lab devices, and also to generate the reports which display the info. from the devices. The reports are also part of the second db. The code works in Access 2000, but once I convert it to 2007, the code in the second db cannot find the function calls in the first db that dictate the progression from screen to screen. I have tried importing the modules into the second db, and I have tried linking them, but it still doesn't work. The error message is #438: "Object doesn't support this property or method." Any suggestions would be greatly appreciated. Here is the code for the first function that is not being called correctly: Description: ' This routine is used to return to the calling form and close the active form. ' ' Input: ' strFormCalled --- the active form ' strCallingForm --- the form that called the active form ' blnUnhideOrOpen --- whether to open or just unhide form Public Sub basReturnToCallingForm(ByVal strFormCalled As String, ByVal _ strCallingForm As Variant, Optional blnUnhideOrOpen As Boolean = True) On Error GoTo err_basReturnToCaliingForm If Not basIsBlankString(strCallingForm) And blnUnhideOrOpen Then DoCmd.OpenForm strCallingForm, acNormal Else Call basUnHideForm(strCallingForm) End If Call basCloseForm(strFormCalled) exit_basReturnToCaliingForm: Exit Sub err_basReturnToCaliingForm: Err.Raise Err.Number, "basReturnToCaliingForm", Err.Description End Sub I will post the second function shortly, but I have to go to a meeting... The second funtion that isn't 'working' is a cmdStartClick that is supposed to be called when a user initializes a pump. However, within that function, it's also sticking on a line that is supposed to progress to the next form in the db. The other thing is that the code works in Access 2002, but not in Access 2007...

What is the best way of doing this? (WCF 4)

- by Jason Porter

I have a multith-threaded, continusly running application that connects with multiple devices via TCP/IP sockets and exposes a set of WCF API's for controlling, monitoring and reporting on these devices. I would like to host this on IIS for the ususal reasons of not having to worry about re-starting the app in case of errors. So the issue I have is the main application running in parallel with the WCF Servies. To accomplish this I use the static AppInitialize class to start a thread which has the main applicaiton loop. The WCF services mostly report or control the shared objects with this thread. There are two problems that I see with this approach. One is that if the thread dies, IIS has no clue to re-start it so I have to play some tricks with some WCF calls. The other is that the backrgound thread deals with potentially thousands of devices that are connected permanently (typically a thread per socket connection). So I am not sure if IIS is buying me anything in this case. Another approach that I am thinking is to use WF for the main application that deals with the sockets and host both the WF and my WCF services in IIS using AppFabric. Since I have not use WF or AppFabric I am reaching out to see if this would be good approach or there are better alternative.

Adding an element to a multidimensional array

- by stef

How can I loop through the array below and an element per array, with key "url_slug" and value "foo"? I tried with array_push but that gets rid of the key names (it seems?) Doing a foreach($array as $k = $v) doesn't do it either, I think. The new array should be exactly the same only having 4 elements per array instead of 3, with the key / values above. Array ( [0] => Array ( [name_en] => Test 5 [url_name_nl] => test-5 [cat_name] => mobile ) [1] => Array ( [name_en] => Test 10 [url_name_nl] => test-10 [cat_name] => mobile ) [2] => Array ( [name_en] => Test 25 [url_name_nl] => test-25 [cat_name] => mobile ) ) EDIT: full working solution. A little more complex than originally described foreach ($prods as $key => &$value) { if($key == "cat_name") $slug = $value['cat_name']; $url_slug = $this->lang->line($slug); $value['url_slug'] = $url_slug; }

What does the BIOS setting XHCI Pre-Boot Mode do?

- by Jamie Kitson

I have a BIOS setting called XHCI Pre-Boot Mode. If I have this enabled USB devices which aren't plugged in at boot are never recognised, if I set it to Disabled then USB devices work normally. The brief BIOS description says "Enable this option if you need USB3.0 support in DOS." Which I don't, but it also says "Please note that XHCI controller will be disabled if you set this item as Disabled." So does that mean that USB3 is disabled with this option? Here's a picture of the screen: http://www.flickr.com/photos/jamiekitson/8017563004/

Watchguard Firewall - Issues with SSLVPN

- by David W

I have a client who has a WatchGuard XTM 23 device on site as their primary firewall. I just upgraded its firmware a couple days ago to the latest version for that series, 11.6.6. The problem is that I haven't successfully been able to setup a VPN connection for them. Using the instructions at http://www.watchguard.com/help/docs/webui/11_XTM/en-US/index.html#en-US/mvpn/ssl/configure_fb_for_mvpn_ssl_c.html, I'm trying to setup a VPN with SSL connection: From the firewall web GUI / Dashboard, I go to VPN - Mobile VPN with SSL, I enable it, add the organization's public IP address to which the firewall is connected. I've setup a group in Active Directory named "SSLVPN-Users", verified that the WatchGuard box can talk to the Active Directory Server, and added myself to that group. I then downloaded the WatchGuard Mobile VPN with SSL client onto my own Windows 7 machine, walked to the client's 2nd building across the street (which has a different public internet connection), and tried to connect to the VPN. When I do try to connect with the client, I get the following errors: 2013-06-24T15:41:32.119 Launching WatchGuard Mobile VPN with SSL client. Version 11.6.0 (Build 343814) Built:Jun 13 2012 01:42:55 2013-06-24T15:41:37.595 Requesting client configuration from 184.174.143.176:443 2013-06-24T15:41:50.106 FAILED:Cannot perform http request, timeout 12002 2013-06-24T15:41:50.106 failed to get domain name I discovered today the Firebox System Manager, and its "Traffic Monitor" which gives current log information (refreshes every 5 seconds). Unfortunately, it doesn't look like the client has setup any sort of WatchGuard / Firebox logging server, so actually recording server-side logs to file hasn't been done. I can work on implementing that if I need to. I noticed that if I try to ping the client's public IP address from an outside source, I don't get a response back (unless I added a policy into the firewall to allow ICMP traffic from "External", which I successfully did a few seconds ago for testing purposes - that rule has since been reverted to not respond to external ping requests). There's a policy in the firewall for allowing SSLVPN Traffic authentication requests coming from any external source TO the Firebox, and then to do the authentication / actually allow the VPN traffic, there's a policy allowing traffic for anyone in the SSLVPN-Users group to flow between that user and the inside network. So my questions are: Has anyone seen these errors before from the Watchguard VPN Client, and/or do you have any suggestions on how I can resolve that error? If I need to setup logging server to grab the firewall logs (in order to further troubleshoot this issue), how complicated a task is that and does it require a lot of system resources? The organization I'm consulting with only has 1 server and not a lot of resources or technical know-how.

asterisk/freeswitch in nat/no-nat setup

- by pQd

hi, my current setup - i use bunch of sip hard-phones around few offices. all devices have two sip accounts configured - one on internal sip proxy [for calls between the branches], another - at 3rd party voip providers [ since it's in different countries - those are different providers, but that's irrelevant ]. i was thinking about terminating sip calls on something like asterisk/freeswitch server and having all sip-devices log on just once to such server[s] - mostly to provide things like voicemail, groupcalls, redirections etc. it seems perfectly doable but there is one problem - i cannot find examples how to prepare for nat/no nat. for calls routed to from/to 3rd party voip operator - i'll need handling for nat/stun etc, but for handling of internal calls - i do not want any nat, all traffic should go via vpns to different branches. can you provide me some hints how to configure it? any tutorials? thanks!

My laptop causes the wireless router to stop working

- by Pier

hello all, it's happening something strange to my wireless connection. The wireless connection works fine with all the devices at home, except with my laptop (Toshiba satellite, WIN 7 64): as I start it, the wireless network shuts off and the connection disappears also for the other devices. I can use internet only plugging the laptop with an ethernet cable, and I have to shut off the wireless card, to allow the other people in the house to use the wireless connection. I tried to update the firmware (it is a D-Link DIR 615) but it's up to date, and reconfigure the router, but all indicates that the problem is caused by my laptop. I'm currently doing an antivirus scanning, but the computer seems to be clean. Any suggestion?

Linux boot on a raid1 software raid ?

- by azera

Hello I am trying to convert my single disk boot to a raid1 boot So far here is what i have: I sucessfully create the raid 1 as degraded with the new drive alone, I copied all the data on it I can mount that raid 1, see its files etc I already have a raid5 that is working on the same box (although not booting on it) I have installed grub on both drive When grub boot, it loads the kernel alright, but during the kernel boot it fails to load the "root block device" The kernel tells me : 1 - detected that root device is an md device 2 - determining root devices 3 - mounting root 4 - mounting /dev/md125 on /newroot failed: input/output error. Please enter another root device: ... At this point, if I enter /dev/sda3 (my "old" root device that isn't converted to raid yet) everything boots fine without the root. The /dev/md125 device is indeed created but it seems to be created after the error happens, as in it creates it after loading the device, when mdadm is loaded. Somehow it looks like it can't/doesn't load the raid array before it needs to mount it, and I don't know how I can solve that. My config files (taken from the system once it boots with sda3 as root device): $ cat /etc/mdadm.conf ARRAY /dev/md/md0-r5 metadata=0.90 UUID=1a118934:c831bdb3:64188b84:66721085 ARRAY /dev/md125 metadata=0.90 UUID=48ec4190:a80d4dde:64188b84:66721085 $ cat /proc/mdstat Personalities : [raid1] [raid6] [raid5] [raid4] [raid0] [raid10] md125 : active raid1 sdc3[1] 477853312 blocks [2/1] [_U] md127 : active raid5 sdd[0] sdf[3] sdb[2] sde[1] 4395415488 blocks level 5, 64k chunk, algorithm 2 [4/4] [UUUU] unused devices: <none> $ cat /boot/grub/menu.lst default 0 timeout 8 splashimage=(hd0,0)/boot/grub/splash.xpm.gz title Gentoo Linux 2.6.31-r10 root (hd0,0) #kernel /boot/kernel-genkernel-x86_64-2.6.31-gentoo-r10 root=/dev/ram0 real_root=/dev/sda3 kernel /boot/kernel-genkernel-x86_64-2.6.31-gentoo-r10 root=/dev/md125 md=125,/dev/sdc3,/dev/sda3 initrd /boot/initramfs-genkernel-x86_64-2.6.31-gentoo-r10 # blkid /dev/sda1: UUID="89fee223-b845-4e0a-8a0b-e6cf695d5bcf" TYPE="ext2" /dev/sda2: UUID="a72296a8-d7d4-447f-a34b-ee920fd1a767" TYPE="swap" /dev/sda3: UUID="97eb0a6a-c385-4a9d-bf74-c0bab1fa4dc1" TYPE="ext3" /dev/sdb: UUID="1a118934-c831-bdb3-6418-8b8466721085" TYPE="linux_raid_member" /dev/sdc1: UUID="d36537fd-19a0-b8a3-6418-8b8466721085" TYPE="linux_raid_member" /dev/sdd: UUID="1a118934-c831-bdb3-6418-8b8466721085" TYPE="linux_raid_member" /dev/sde: UUID="1a118934-c831-bdb3-6418-8b8466721085" TYPE="linux_raid_member" /dev/md127: UUID="13a41589-4cf1-4c04-91ca-37484182c783" TYPE="ext4" /dev/sdf: UUID="1a118934-c831-bdb3-6418-8b8466721085" TYPE="linux_raid_member" /dev/sdc2: UUID="a1916397-1b48-45d7-9f98-73aa521e882f" TYPE="swap" /dev/sdc3: UUID="48ec4190-a80d-4dde-6418-8b8466721085" TYPE="linux_raid_member" /dev/md125: UUID="c947ed64-1d4d-4d1d-b4d2-24669fff916e" SEC_TYPE="ext2" TYPE="ext3" # mdadm -E mdadm: No devices to examine # fdisk -l Disk /dev/sda: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xe975e9fc Device Boot Start End Blocks Id System /dev/sda1 1 5 40131 83 Linux /dev/sda2 6 1311 10490445 82 Linux swap / Solaris /dev/sda3 1312 60801 477853425 83 Linux Disk /dev/sdc: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xe975e9fc Device Boot Start End Blocks Id System /dev/sdc1 1 5 40131 83 Linux /dev/sdc2 6 1311 10490445 82 Linux swap / Solaris /dev/sdc3 1312 60801 477853425 83 Linux Disk /dev/md125: 489.3 GB, 489321791488 bytes 2 heads, 4 sectors/track, 119463328 cylinders Units = cylinders of 8 * 512 = 4096 bytes Disk identifier: 0x00000000 Disk /dev/md125 doesn't contain a valid partition table

How to charge an iPhone on a Windows PC without Installing iTunes

- by Martin Hollingsworth

I want to be able to charge my iPhone on my work computer, which is running Windows Server 2008 SP1 64-Bit. When I plug the iPhone in with the USB cable, it will not charge. Windows attempts to locate a driver for the device but only comes up with a generic Camera device and even if I allow that to be installed, the iPhone still does not charge. I have checked the computer's BIOS settings and did not find anything relating to power on the USB devices. I also tried this on ports at the back of the computer in addition to those on the front. The PC is a Dell Optiplex 780. As far as I can tell USB devices do not charge unless Windows has installed an appropriate driver. Since it is a work computer I do not want to install iTunes which does include a driver. I have a workaround that I will post as an answer for reference.

Create firewall "profiles" for Windows 7

- by Samantha

Is there any way to configure a couple of firewall profiles in Windows 7? As I use mobile broadband on when traveling, I don't want virus scanner/windows updates etc running and chewing up my mobile data allocation. So would love to find a way to block everything except email ports and perhaps http. The kicker though is that when I'm back in the office, I want to just click a button to get my original firewall settings back. In the office I use WiFi and on the road tether to my android phone, also via WiFi, so can't restrict via network interface. Any ideas?

howto only tunnel specific hosts route through openvpn client on tomato

- by kcome

I am relatively newbie in networking world although I did coding and know some sysadmin background for a long time. and here I'm only one step from my destination. The whole picture is : at home I use one LinkSys E3000 as the gateway(don't know yet if this is it's name), wireless AP and no other routing/switching devices. It serves 1 PC and 1 Mac with LAN, 1 Mac Mini + 1 iPad + 2 smartphones with WIFI. My goal is use an openvpn client on the E3000 (with tomato firmware) and make my iPad and smartphone's all WiFi traffic through it, and other devices route remain the same non-openvpn route. So far I'm able to connect openvpn client on E3000 to an openvpn server, tunnel all my devices' all traffic through that openvpn connection. What's left is howto selectively route by source IP (at least in my guessing) to the tunnel while don't bother others. I had learned some 'iptables' and 'route' in past few days however without much luck, so here comes my question. Here are some info which will help you get the structure. ifconfig -a output, some useless lines striped, and in the web interface C0:C1:C0:1A:E0:28 is WAN, C0:C1:C0:1A:E0:27 is LAN, C0:C1:C0:1A:E0:29 is 2.4G wifi AP, C0:C1:C0:1A:E0:2A is 5G wifi AP. root@router:/tmp/home/root# ifconfig -a br0 Link encap:Ethernet HWaddr C0:C1:C0:1A:E0:27 inet addr:192.168.1.1 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 eth0 Link encap:Ethernet HWaddr C0:C1:C0:1A:E0:27 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 eth1 Link encap:Ethernet HWaddr C0:C1:C0:1A:E0:29 UP BROADCAST RUNNING ALLMULTI MULTICAST MTU:1500 Metric:1 eth2 Link encap:Ethernet HWaddr C0:C1:C0:1A:E0:2A UP BROADCAST RUNNING ALLMULTI MULTICAST MTU:1500 Metric:1 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host ppp0 Link encap:Point-to-Point Protocol inet addr:172.200.1.43 P-t-P:172.200.0.1 Mask:255.255.255.255 UP POINTOPOINT RUNNING MULTICAST MTU:1480 Metric:1 vlan1 Link encap:Ethernet HWaddr C0:C1:C0:1A:E0:27 UP BROADCAST RUNNING ALLMULTI MULTICAST MTU:1500 Metric:1 vlan2 Link encap:Ethernet HWaddr C0:C1:C0:1A:E0:28 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 wl0.1 Link encap:Ethernet HWaddr C0:C1:C0:1A:E0:29 BROADCAST MULTICAST MTU:1500 Metric:1 brctl show output root@router:/tmp/home/root# brctl show bridge name bridge id STP enabled interfaces br0 8000.c0c1c01ae027 no vlan1 eth1 eth2 before openvpn route-up script root@router:/tmp/home/root# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 172.200.0.1 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 br0 127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo 0.0.0.0 172.200.0.1 0.0.0.0 UG 0 0 0 ppp0 openvpn server push PUSH: Received control message: 'PUSH_REPLY,redirect-gateway,dhcp-option DNS 8.8.8.8,route 172.20.0.1,topology net30,ping 10,ping-restart 120,ifconfig 172.20.0.6 172.20.0.5' openvpn's stock route-up script Apr 24 14:52:06 router daemon.notice openvpn[1768]: /sbin/ifconfig tun11 172.20.0.6 pointopoint 172.20.0.5 mtu 1500 Apr 24 14:52:08 router daemon.notice openvpn[1768]: /sbin/route add -net 72.14.177.29 netmask 255.255.255.255 gw 172.200.0.1 Apr 24 14:52:08 router daemon.notice openvpn[1768]: /sbin/route add -net 0.0.0.0 netmask 128.0.0.0 gw 172.20.0.5 Apr 24 14:52:08 router daemon.notice openvpn[1768]: /sbin/route add -net 128.0.0.0 netmask 128.0.0.0 gw 172.20.0.5 Apr 24 14:52:08 router daemon.notice openvpn[1768]: /sbin/route add -net 172.20.0.1 netmask 255.255.255.255 gw 172.20.0.5 route after openvpn root@router:/tmp/home/root# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 172.20.0.5 0.0.0.0 255.255.255.255 UH 0 0 0 tun11 72.14.177.29 172.200.0.1 255.255.255.255 UGH 0 0 0 ppp0 172.200.0.1 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0 172.20.0.1 172.20.0.5 255.255.255.255 UGH 0 0 0 tun11 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 br0 127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo 0.0.0.0 172.20.0.5 128.0.0.0 UG 0 0 0 tun11 128.0.0.0 172.20.0.5 128.0.0.0 UG 0 0 0 tun11 0.0.0.0 172.200.0.1 0.0.0.0 UG 0 0 0 ppp0 something I had noticed and tried: * on the web interface of openvpn client there is an option "Create NAT on tunnel", if i check this, there is the following script (probably executed after openvpn connection established) root@router:/tmp/home/root# cat /tmp/etc/openvpn/fw/client1-fw.sh #!/bin/sh iptables -I INPUT -i tun11 -j ACCEPT iptables -I FORWARD -i tun11 -j ACCEPT iptables -t nat -I POSTROUTING -s 192.168.1.0/255.255.255.0 -o tun11 -j MASQUERADE if i uncheck this option, the last line will not appear.

Windows Media Center says "Searching for tuners" when I try to play live TV

- by Louis

After upgrading from Windows 8 Pro with Media Center to the 8.1 preview, I need some help in being able to watch live TV again. When I try to now, it says Please Wait. Searching for tuners. I tried reinstalling the software for the Hauppauge WinTV DCR-2650 TV tuner, and upgrading the firmware for both the tuner and the Cisco STA-1520 tuning adapter. I also tried swapping around the USB ports, cold-booting the devices, and running the Set Up TV Signal setting in WMC, but that says The TV signal cannot be configured because a TV tuner was not detected. Both devices look fine in Device Manager, reporting the "This device is working properly" status. I'm not sure if this is related, but I did have some network connectivity issues immediately after upgrading to Windows 8.1 where my either my subnet mask or default gateway was missing, and since the TV tuner shows up as a network device, I wonder if that might be related. However, I really don't know how those settings should look and Hyper-V sort of further complicates things with the virtual Ethernet adapters:
