• What /else/ causes this?

  - by Mordachai

  MFC Toolbox Library.lib(SimpleFileIO.obj) : error LNK2005: _wcsnlen already defined in libcmtd.lib(wcslen_s.obj) fatal error LNK1169: one or more multiply defined symbols found This is driving me nuts. Normally, one would get this if the various projects that are a part of their solution do not agree on which CRT to use (single threaded, multi-threaded, release or debug). However, I have been over this thing about 500 times now, and they all agree. Background: this is a VS 2010 project just converted from VS 2008. MFC Toolbox Library.lib is set to compile as a static library, using /MTd, as is the target .exe I am trying to compile in this solution. Further, the solution that this is being converted from (VS 2008) already compiles & links properly!!! So it's not like that there is a disagreement between the two .vcproj's - or at least there wasn't before the conversion. Furthermore, the MFC Toolbox Library is used by about 25 other projects in another solution - and in that solution (Master Build English) it compiles & links against those other projects without complaint in both debug and release targets. I have just spent the last hour going over every single project property for this target project (Cimex Header Viewer) vs. several different target exe projects in Master Build English solution - and I cannot find a difference. They appear to be identical, excepting that they're different names. I've tried doing a clean & build all. I'm simply out of ideas. Does anyone have a thought on what else I might investigate??? I think I'm ready to start chewing glass. :(

• Now Available &ndash; Windows Azure SDK 1.6

  - by Shaun

  Microsoft has just announced the Windows Azure SDK 1.6 and the Windows Azure Tools for Visual Studio 1.6. Now people can download the latest product through the WebPI. After you downloaded and installed the SDK you will find that The SDK 1.6 can be stayed side by side with the SDK 1.5, which means you can still using the 1.5 assemblies. But the Visual Studio Tools would be upgraded to 1.6. Different from the previous SDK, in this version it includes 4 components: Windows Azure Authoring Tools, Windows Azure Emulators, Windows Azure Libraries for .NET 1.6 and the Windows Azure Tools for Microsoft Visual Studio 2010. There are some significant upgrades in this version, which are Publishing Enhancement: More easily connect to the Windows Azure when publish your application by retrieving a publish setting file. It will let you configure some settings of the deployment, without getting back to the developer portal. Multi-profiles: The publish settings, cloud configuration files, etc. will be stored in one or more MSBuild files. It will be much easier to switch the settings between vary build environments. MSBuild Command-line Build Support. In-Place Upgrade Support.   Publishing Enhancement So let’s have a look about the new features of the publishing. Just create a new Windows Azure project in Visual Studio 2010 with a MVC 3 Web Role, and right-click the Windows Azure project node in the solution explorer, then select Publish, we will find the new publish dialog. In this version the first thing we need to do is to connect to our Windows Azure subscription. Click the “Sign in to download credentials” link, we will be navigated to the login page to provide the Live ID. The Windows Azure Tool will generate a certificate file and uploaded to the subscriptions those belong to us. Then we will download a PUBLISHSETTINGS file, which contains the credentials and subscriptions information. The Visual Studio Tool will generate a certificate and deployed to the subscriptions you have as the Management Certificate. The VS Tool will use this certificate to connect to the subscription in the next step. In the next step, I would back to the Visual Studio (the publish dialog should be stilling opened) and click the Import button, select the PUBLISHSETTINGS file I had just downloaded. Then all my subscriptions will be shown in the dropdown list. Select a subscription that I want the application to be published and press the Next button, then we can select the hosted service, environment, build configuration and service configuration shown in the dialog. In this version we can create a new hosted service directly here rather than go back to the developer portal. Just select the <Create New …> item in the hosted service. What we need to do is to provide the hosted service name and the location. Once clicked the OK, after several seconds the hosted service will be established. If we went to the developer portal we will find the new hosted service in my subscription. a) Currently we cannot select the Affinity Group when create a new hosted service through the Visual Studio Publish dialog. b) Although we can specify the hosted service name and DNS prefixing through the developer portal, we cannot do so from the VS Tool, which means the DNS prefixing would be the same as what we specified for the hosted service name. For example, we specified our hosted service name as “Sdk16Demo”, so the public URL would be http://sdk16demo.cloudapp.net/. After created a new hosted service we can select the cloud environment (production or staging), the build configuration (release or debug), and the service configuration (cloud or local). And we can set the Remote Desktop by check the related checkbox as well. One thing should be note is that, in this version when we set the Remote Desktop settings we don’t need to specify a certificate by default. This is because the Visual Studio will generate a new certificate for us by default. But we can still specify an existing certificate for RDC, by clicking the “More Options” button. Visual Studio Tool will create another certificate for the Remote Desktop connection. It will NOT use the certificate that managing the subscription. We also can select the “Advanced Settings” page to specify the deployment label, storage account, IntelliTrace and .NET profiling information, etc.. Press Next button, the dialog will display all settings I had just specified and it will save them as a new profile. The last step is to click the Publish button. Since we enabled the Remote Desktop feature, the first step of publishing was uploading the certificate. And then it will verify the storage account we specified and upload the package, then finally created the website in Windows Azure.   Multi-Profiles After published, if we back to the Visual Studio we can find a AZUREPUBXML file under the Profiles folder in the Azure project. It includes all settings we specified before. If we publish this project again, we can just use the current settings (hosted service, environment, RDC, etc.) from this profile without input them again. And this is very useful when we have more than one deployment settings. For example it would be able to have one AZUREPUBXML profile for deploying to testing environment (debug building, less roles with RDC and IntelliTrace) and one for production (release building, more roles but without IntelliTrace).   In-Place Upgrade Support Let’s change some codes in the MVC pages and click the Publish menu from the azure project node. No need to specify any settings,  here we can use the pervious settings by loading the azure profile file (AZUREPUBXML). After clicked the Publish button the VS Tool brought a dialog to us to indicate that there’s a deployment available in the hosted service environment, and prompt to REPLACE it or not. Notice that in this version, the dialog tool said “replace” rather than “delete”, which means by default the VS Tool will use In-Place Upgrade when we deploy to a hosted service that has a deployment already exist. After click Yes the VS Tool will upload the package and perform the In-Place Upgrade. If we back to the developer portal we can find that the status of the hosted service was turned to “Updating…”. But in the previous SDK, it will try to delete the whole deployment and publish a new one.   Summary When the Microsoft announced the features that allows the changing VM size via In-Place Upgrade, they also mentioned that in the next few versions the user experience of publishing the azure application would be improved. The target was trying to accomplish the whole publish experience in Visual Studio, which means no need to touch developer portal any more. In the SDK 1.6 we can see from the new publish dialog, as a developer we can do the whole process, includes creating hosted service, specifying the environment, configuration, remote desktop, etc. values without going back the the developer portal.   Hope this helps, Shaun All documents and related graphics, codes are provided "AS IS" without warranty of any kind.

• ANTS Memory Profiler 7.0

  - by James Michael Hare

  I had always been a fan of ANTS products (Reflector is absolutely invaluable, and their performance profiler is great as well – very easy to use!), so I was curious to see what the ANTS Memory Profiler could show me. Background While a performance profiler will track how much time is typically spent in each unit of code, a memory profiler gives you much more detail on how and where your memory is being consumed and released in a program. As an example, I’d been working on a data access layer at work to call a market data web service.  This web service would take a list of symbols to quote and would return back the quote data.  To help consolidate the thousands of web requests per second we get and reduce load on the web services, we implemented a 5-second cache of quote data.  Not quite long enough to where customers will typically notice a quote go “stale”, but just long enough to be able to collapse multiple quote requests for the same symbol in a short period of time. A 5-second cache may not sound like much, but it actually pays off by saving us roughly 42% of our web service calls, while still providing relatively up-to-date information.  The question is whether or not the extra memory involved in maintaining the cache was worth it, so I decided to fire up the ANTS Memory Profiler and take a look at memory usage. First Impressions The main thing I’ve always loved about the ANTS tools is their ease of use.  Pretty much everything is right there in front of you in a way that makes it easy for you to find what you need with little digging required.  I’ve worked with other, older profilers before (that shall remain nameless other than to hint it was created by a very large chip maker) where it was a mind boggling experience to figure out how to do simple tasks. Not so with AMP.  The opening dialog is very straightforward.  You can choose from here whether to debug an executable, a web application (either in IIS or from VS’s web development server), windows services, etc. So I chose a .NET Executable and navigated to the build location of my test harness.  Then began profiling. At this point while the application is running, you can see a chart of the memory as it ebbs and wanes with allocations and collections.  At any given point in time, you can take snapshots (to compare states) zoom in, or choose to stop at any time.  Snapshots Taking a snapshot also gives you a breakdown of the managed memory heaps for each generation so you get an idea how many objects are staying around for extended periods of time (as an object lives and survives collections, it gets promoted into higher generations where collection becomes less frequent). Generating a snapshot brings up an analysis view with very handy graphs that show your generation sizes.  Almost all my memory is in Generation 1 in the managed memory component of the first graph, which is good news to me, because Gen 2 collections are much rarer.  I once3 made the mistake once of caching data for 30 minutes and found it didn’t get collected very quick after I released my reference because it had been promoted to Gen 2 – doh! Analysis It looks like (from the second pie chart) that the majority of the allocations were in the string class.  This also is expected for me because the majority of the memory allocated is in the web service responses, so it doesn’t seem the entities I’m adapting to (to prevent being too tightly coupled to the web service proxy classes, which can change easily out from under me) aren’t taking a significant portion of memory. I also appreciate that they have clear summary text in key places such as “No issues with large object heap fragmentation were detected”.  For novice users, this type of summary information can be critical to getting them to use a tool and develop a good working knowledge of it. There is also a handy link at the bottom for “What to look for on the summary” which loads a web page of help on key points to look for. Clicking over to the session overview, it’s easy to compare the samples at each snapshot to see how your memory is growing, shrinking, or staying relatively the same.  Looking at my snapshots, I’m pretty happy with the fact that memory allocation and heap size seems to be fairly stable and in control: Once again, you can check on the large object heap, generation one heap, and generation two heap across each snapshot to spot trends. Back on the analysis tab, we can go to the [Class List] button to get an idea what classes are making up the majority of our memory usage.  As was little surprise to me, System.String was the clear majority of my allocations, though I found it surprising that the System.Reflection.RuntimeMehtodInfo came in second.  I was curious about this, so I selected it and went into the [Instance Categorizer].  This view let me see where these instances to RuntimeMehtodInfo were coming from. So I scrolled back through the graph, and discovered that these were being held by the System.ServiceModel.ChannelFactoryRefCache and I was satisfied this was just an artifact of my WCF proxy. I also like that down at the bottom of the Instance Categorizer it gives you a series of filters and offers to guide you on which filter to use based on the problem you are trying to find.  For example, if I suspected a memory leak, I might try to filter for survivors in growing classes.  This means that for instances of a class that are growing in memory (more are being created than cleaned up), which ones are survivors (not collected) from garbage collection.  This might allow me to drill down and find places where I’m holding onto references by mistake and not freeing them! Finally, if you want to really see all your instances and who is holding onto them (preventing collection), you can go to the “Instance Retention Graph” which creates a graph showing what references are being held in memory and who is holding onto them. Visual Studio Integration Of course, VS has its own profiler built in – and for a free bundled profiler it is quite capable – but AMP gives a much cleaner and easier-to-use experience, and when you install it you also get the option of letting it integrate directly into VS. So once you go back into VS after installation, you’ll notice an ANTS menu which lets you launch the ANTS profiler directly from Visual Studio.   Clicking on one of these options fires up the project in the profiler immediately, allowing you to get right in.  It doesn’t integrate with the Visual Studio windows themselves (like the VS profiler does), but still the plethora of information it provides and the clear and concise manner in which it presents it makes it well worth it. Summary If you like the ANTS series of tools, you shouldn’t be disappointed with the ANTS Memory Profiler.  It was so easy to use that I was able to jump in with very little product knowledge and get the information I was looking it for. I’ve used other profilers before that came with 3-inch thick tomes that you had to read in order to get anywhere with the tool, and this one is not like that at all.  It’s built for your everyday developer to get in and find their problems quickly, and I like that!

• Incoming traceroute blocked by ufw

  - by Tobias Timpe

  One of my Proxmox VMs running Ubuntu 13.04 won't accept incoming trace routes while ufw is enabled. What command do give ufw to allow incoming traceroute(6)s? The following shows up in the syslog with ufw enabled: 50:15:15:aa:ae:8d:7d:e4:7a:97:08:00 SRC=79.236.233.97 DST=78.46.101.252 LEN=52 TOS=0x00 PREC=0x00 TTL=1 ID=33400 PROTO=UDP SPT=63757 DPT=33466 LEN=32 Nov 4 16:20:36 web kernel: [8078158.260409] [UFW BLOCK] IN=eth0 OUT= MAC=00:50:56:15:15:aa:ae:8d:7d:e4:7a:97:08:00 SRC=79.236.233.97 DST=78.46.101.252 LEN=52 TOS=0x00 PREC=0x00 TTL=1 ID=33401 PROTO=UDP SPT=63757 DPT=33467 LEN=32 Nov 4 16:20:41 web kernel: [8078163.262626] [UFW BLOCK] IN=eth0 OUT= MAC=00:50:56:15:15:aa:ae:8d:7d:e4:7a:97:08:00 SRC=79.236.233.97 DST=78.46.101.252 LEN=52 TOS=0x00 PREC=0x00 TTL=2 ID=33402 PROTO=UDP SPT=63757 DPT=33468 LEN=32 Nov 4 16:20:46 web kernel: [8078168.262927] [UFW BLOCK] IN=eth0 OUT= MAC=00:50:56:15:15:aa:ae:8d:7d:e4:7a:97:08:00 SRC=79.236.233.97 DST=78.46.101.252 LEN=52 TOS=0x00 PREC=0x00 TTL=2 ID=33403 PROTO=UDP SPT=63757 DPT=33469 LEN=32 Nov 4 16:20:51 web kernel: [8078173.260521] [UFW BLOCK] IN=eth0 OUT= MAC=00:50:56:15:15:aa:ae:8d:7d:e4:7a:97:08:00 SRC=79.236.233.97 DST=78.46.101.252 LEN=52 TOS=0x00 PREC=0x00 TTL=2 ID=33404 PROTO=UDP SPT=63757 DPT=33470 LEN=32 And the trace route just ends in starts after the Proxmox host machine.

• Problem booting virtual machine after converting VMDK to VHD

  - by vg1890

  I used the VMWare VCenter Converter Standalone Client to convert a physical drive on my old PC to a virtual drive. The conversion worked fine and I ended up with a valid VMDK file. Next, I wanted to convert the VMDK to a VHD for use with Microsoft Virtual PC, since that's what I use on my new box. I used WinImage for the conversion and that worked fine, too. I can access the files from the virtual drive through WinImage. However, when I create a new virtual machine using Virtual PC and add the existing VHD file, the machine doesn't boot. The initial boot screen flashes with the amount of RAM and then the screen goes black. If I turn off the VM and reboot in safe mode I can see the drivers being loaded until eventually it gets to crcdisk.sys and hangs indefinitely. Any ideas how to fix this? I'm not opposed to starting over from scratch if there's another method to turn my physical machine into a Virtual PC VM. Thanks! EDIT - I should add that the virtual drive is a system boot drive and not a secondary drive. EDIT - I tried booting from the install CD and doing a repair. The result was that the system could not be repaired due to a "driver error."

• KVM recommendations

  - by alex

  I recently tried out a cheaper KVM solution, a dual monitor one with a USB hub and audio/mic support. It seemed the perfect KVM. However, these are my experiences. When using my keyboard via the PS/2 connection, none of my multimedia keys work (useful, because it has a volume control and my speakers do not, only on a wireless remote control.) I plugged the keyboard in via the USB port - and it seemed to work. However, I believe to switch the hub from PC to Mac, you need to use a keyboard combo, which is only supported when the keyboard is plugged in via PS/2 Sometimes the middle mouse button doesn't work when connected via PS/2. The multi monitor is VGA - I just found out by the looks of things my Mac Mini outputs DVI Digital only (though this is my fault!). Mac works with 2 screens, but switching and switching back can cause it not to display on the 2nd screen unless I go detect displays again. My question is - is there a KVM out there that supports these features? USB keyboard and mouse inputs will full multimedia keys support Dual monitor DVI connections Hotkey to change PCs and physical button USB hub Emulate screens attached when switching to a different computer Works with PC and Mac Audio / Microphone support Does one exist, that won't cost the world? So far the only one that seems to support all this (that I can tell) is this one. UPDATE I ended up buying the Aten CS1642. It's expensive, but it seems to work great!

• Remote Desktop to Server 2008R2 fails from one particular Win7 client

  - by Jesse McGrew

  I have a VPS running Windows Web Server 2008 R2. I'm able to connect using Remote Desktop from my home PC (Windows 7), personal laptop (Windows 7), and work laptop (Windows XP). However, I cannot connect from my work PC (Windows 7). I receive the error "The logon attempt failed" in the RDP client, and the server event log shows "An account failed to log on" with this explanation: Subject: Security ID: NULL SID Account Name: - Account Domain: - Logon ID: 0x0 Logon Type: 3 Account For Which Logon Failed: Security ID: NULL SID Account Name: username Account Domain: hostname Failure Information: Failure Reason: Unknown user name or bad password. Status: 0xc000006d Sub Status: 0xc0000064 Process Information: Caller Process ID: 0x0 Caller Process Name: - Network Information: Workstation Name: JESSE-PC Source Network Address: - Source Port: - Detailed Authentication Information: Logon Process: NtLmSsp Authentication Package: NTLM Transited Services: - Package Name (NTLM only): - Key Length: 0 I can connect from the offending work PC if I start up Windows XP Mode and use the RDP client inside that. The server is part of a domain but my account is local, so I'm logging in using a username of the form hostname\username. None of the clients are part of a domain. The server uses a self-signed certificate, and connecting from home I get a warning about that, but connecting from work I just get the logon error.

• My computer loses network connectivity every 30 minutes

  - by Logan Garland

  My LAN connected PC loses network connectivity every 30 minutes. It has a static IP address and I've checked to make sure there aren't any IP conflicts on my network. If I'm streaming from that PC to my Xbox the stream will be interrupted and it normally takes about a minute to come back online. The same happens if I'm actually on the PC and just browsing the web. I'm looking for suggestions on how to track down this issue. I've tried checking the available logs on my router to see if there is an issue with DCHP but have been unsuccessful in finding any evidence. Any suggestions would be helpful. I can't think of any recent changes to my network, PC or software installations that may have caused this. I am a software developer and have intermediate networking knowledge. EDIT: During one outage I told windows to troubleshoot the network problem and it said that it could automatically fix the problem by changing DCHP info. It basically said my network adapter from static to automatically obtain. This did fix the issue quicker than just waiting it out, but the outage occurred again 30 minutes later even when leaving those settings.

• Low CPU performance with low usage and clock - Windows 8.1

  - by Daniele

  I recently deleted everything from my PC and reinstalled Windows 8.1 from scratch. When I first booted into Windows everything was extremely slow though the CPU usage was very low (about 1%). After installing some drivers the problem seemed to be solved, I was able to use my PC normally. Today I installed a game and I noticed a strange behavior: the game was playable but the performance worsened more and more in the time. This is the situation BEFORE opening the game (normal): This is AFTER some minutes inside the game (low CPU usage and clock): Some information about my system: PC: Sony Vaio S13 (SVS13A1C5E) OS: Windows 8.1 CPU: Intel Core i7-3520M 2.90GHz GPU(1): Intel HD Graphics 4000 GPU(2): NVIDIA GeForce GT 640M LE I tried searching for new drivers and other solutions but noting worked and I don't know what is the cause. I did not checked the temperatures but the fans are not running fast and the PC does not look overheated. Update: Max CPU Temp: 66°C, Max GPU Temp: 61°C The strange thing is that the GPU load is 99% (GPU-Z) and the fan is almost silent. Update 2: I had troubles with Sony Vaio software, I can't get the FN keys and the STAMINA/SPEED switch to work (it is a physical switch to enable/disable the Nvidia card and change the Power Profile). I'm saying this because I remember that before reinstalling Windows there was an option in the Vaio Control Center (now it is not there anymore) that allowed me to choose from something like "priority to performance (ventilation)" or "priority to silence". The current behavior looks like a "priority to silence", but I can't get the stamina-speed switch to work and so I don't see similar oprions in the Vaio Control Center. I don't know if the problem is related to this.

• One host on a network can't connect to one other host

  - by Max Williams

  I'm on a local network with a few other people. On of the hosts is a virtual machine running in virtualbox on a mac, which has the ip address 192.168.0.35 (the VM that is, not the mac host). Everyone except one guy can connect (ie ping, ssh etc) to that machine. When that one guy tries to ping it he gets Request timeout for icmp_seq 0 Request timeout for icmp_seq 1 Request timeout for icmp_seq 2 which i understand is just how certain mac os's report an unreachable connection. He can ping all the other hosts on the network, ie our computers, and we can all ping the VM fine and connect to it with no problems etc. His ip is 192.168.0.17. I ssh'd onto his machine (as a new user 'anon') and saw the same problems. I can ssh onto the 192.168.0.35 VM as well. From there, i can ping other users, but when i ping the problem guy, it's unreachable that way round as well. He restarted his mac, and was fine for a while. Then, just stopped working again. He's got a different IP to before. Any ideas, anyone? Don't know enough about this stuff to even diagnose the problem. thanks, max

• Can't view other computers on Network

  - by Darkart

  Systems: My Machine: Windows 7 Ultimate connected through ethernet into router Her Machine--Other Machine: Windows 7 Ultimate connected through wireless Router:F5D8236-4 N Wireless Router Version 1 Firmware: 2.01.03 (Apr 28 2009) ISP: Comcast Problem: I can not view the "Other Machine" on the network at all. I opened command prompt and ran net view and saw the pc name. I tried pinging the pc and it times out. Went inside the router and tried viewing the computer on the DHCP list and it can not be seen. I restored the router back to default settings and firmware and completely reset the modem and router, and created home group. I went to the other machine to configure home group settings and made sure that both PC's had identical settings. She was able to see my machine but I could not see hers. I restarted both machines and now we cant see each other at all. Also her PC ("Other Machine") had exclamation mark in the wireless icon but was connected just fine. There is no firewalls on currently or anti-virus enabled, and still can not see each other. Right now I am checking for updated drivers for the wireless card, but my question is could it be the router or something hardware related? I have went through all the settings in the Home group and visited most FAQ's and still no luck. Also as it stands I can not view her machine inside the router DHCP Client List :(

• Broken UAC, cant edit File/folders or change settings in user account

  - by Antoros

  It appears that UAC is broken cant move/delete some file/folders, when asked to use administrative right (and say yes) it shows the loading bar and then nothings gets moved/deleted, no error whatsoever opened control panel, user account and when i click on any option with the Shield (administrative rights) the mouse changes to loading and thengo back to normal, not opening any menu or showing any error Already done a sfc /scannow , no errors found Already used Microsoft's Fix it, reclycle bin broken and repaired, still the same error Used microsoftaccounts tool , this are the errors i got: Problem with microsoft account policy... <- this is the problem (didint fix) Trust this PC <- loop of redirections, cant get to trust this pc (only one with w8) Problems witht sytem registration : i think it is because of the soft system reset Some setting have sync turned off : i never configured anything to sync Rootcauses found and created logs : would like to know where the logs are saved... had to use a ".reg" file to change uac setting to never notify, thinking it would fix this, no, it stoped asking though, i can still open a cmd with Administrative rights, but cant access to UAC settings Accesed Administrator account (net user administrator /active:yes)and even with that account could change any settings so there it is, dont know what else to do in the moment (this pc broke with 8.1 update and was restored to factory configuration, it broke several drivers and kept most of the registry entries, i cant find the cause of this problem. other info: i tried to delete a file in a program folder and couldnt, downloaded unlocker to check first if it was permissions but no, it showed me a msg telling me that there wasnt any error, and if i would like to delete it, clicked on yes, and it did delete it, what amuses me is that i cant without this tool, not even using the feature that takes over ownership Edit: wow, in a not crappy pc chkdsk is fast, completed with no errors found : /

• Finding a backup and synchronization solution

  - by Andrea Zilio

  I'm having difficulties to find a backup and synchronization solution with the following characteristics: Cross-platform: Windows, Linux, Mac Offsite backup (so Internet Backup) Data deduplication Transfer only new/modified bits of modified files Secure: Data encrypted before leaving computer Maintain multiple versions of files (even deleted files) Folder synchronization integrated with backup and across multiple computers connected to the internet (not necessarily in the same LAN) I think that the Folder Sync feature needs a better explanation. The use case is this: you have a desktop pc and a laptop. The desktop pc contains a folder with some files and this folder is part of the backup (so it was selected to be backed up). The laptop does not contain that folder or that files at all. Then you're abroad with your laptop and you need that folder. So you want to be able to open the backup program, select that folder from the backup and download it in your laptop mantaining it synchronized with the backed up version. When you then come back home and switch on your desktop pc you want the folder we're talking about to be updated in the desktop PC. Does anyone knows any service with all these features? I've only found SpiderOak to support all the features I've mentioned but I'm not completely satisfied by the time taken to complete a backup. Sometimes it seems to hang for minutes with no reasons at all and folder synchronization occurs only after all files are backed up (instead folder sync should have a separated queue independent from other backup operations and synchronization should occurs frequently... for example every 5 minutes or less, independently from the frequency of normal backup operations)

• InterVLAN routing on a HP V1910 series switch

  - by tintix

  Recently bought a HP V1910-16G switch (former 3com 29??) with IPv4 routing capabilities. After unpacking I did a firmware upgrade to the latest 5.20 Release 1513P06. I did set up additional VLANs (#2 and #3) and VLAN interfaces for those. The problem is that connected PCs on different VLAN's can't ping each other. Looks like VLAN routing doesn't even work. So here's my setup: VLAN ID VLAN interface 1 10.0.0.21/24 2 10.0.5.1/24 3 10.0.6.1/24 Have one PC connected to VLAN 2 (IP address 10.0.5.2, default gateway 10.0.5.1) and a second PC connected to VLAN 3 (IP address 10.0.6.2, default gateway 10.0.6.1) Routing table: Destination IP Mask Next Hop 0.0.0.0 0.0.0.0 10.0.0.1 10.0.0.0 255.255.255.0 10.0.0.21 10.0.0.21 255.255.255.255 127.0.0.1 10.0.5.0 255.255.255.0 10.0.5.1 10.0.5.1 255.255.255.255 127.0.0.1 10.0.6.0 255.255.255.0 10.0.6.1 10.0.6.1 255.255.255.255 127.0.0.1 127.0.0.0 255.0.0.0 127.0.0.1 127.0.0.1 255.255.255.255 127.0.0.1 The first PC can't ping the second PC one and vice versa. They only can ping their own gateways and that's all. What I'm doing wrong?

• Synergy on macbook with osx mavericks wifi connection

  - by user332956

  I'm trying to set up Synergy with my macbook pro running OS X 10.9.3 as a client and my Windows 7 desktop as a server. I'm having some pretty bad connection problems though when I try to use my mac. Every couple seconds the mouse or the keyboard will stop working entirely then come back. I ran some tests and found that the ping from my desktop to my mac would be very high every third ping or so(1000+ ms) or sometimes even time out. If I ping my desktop from my mac the pings are all reasonably low. I believe that this is a power saving feature of Mavericks and I have found a way to get around it by continually pinging my router on my mac, keeping my wifi card from going to sleep. I'm using this right now to type this up with synergy and have had zero issues. Has anyone else ran into this issue and found a better solution? So far, I think my best bet would be to buy an ethernet adapter but I'd rather not have yet another cable running across my desk.

• Apple Service Diagnostic application on USB key?

  - by Matt 'Trouble' Esse

  I found the following in a text file, and I would like to use the Apple Service Diagnostic Application from a bootable USB key but I cannot find where to download it or set it up? Also is this free software or does it require a separate licence? It sounds like it would be a useful tool for diagnosing Mac problems. The Apple Service Diagnostic application is designed to run both EFI and Mac OS X tests from an external USB hard drive. Apple Service Diagnostic (EFI) runs low-level tests of the hardware directly and does not require Mac OS X, while Apple Service Diagnostic (OS) uses Mac OS X to run tests. Booting and Using the Apple Service Diagnostic Application - Before using Apple Service Diagnostic, disconnect any Ethernet network, USB, and audio cables. - With the USB hard drive containing ASD 3S123 plugged into a USB port, restart the computer and hold down the option key as the computer boots up into the Startup Manager. To run ASD (EFI) select the "ASD EFI 3S123" drive icon and press return or select it with a mouse click. To run ASD (OS) select the "ASD OS 3S123" drive icon and press return or select it with a mouse click. ASD (EFI) will load in 20-30 seconds; ASD (OS) will load in 2-3 minutes. - After running ASD (OS) or ASD (EFI), press the Restart button to restart the computer back into the normal startup volume, or hold down the option key to get back to the Startup Manager. ASD is no longer delivered as an image to be restored onto a DVD. ASD 3S117 and newer versions requires installation onto an external USB hard drive. For more information, please refer to the document "Installing ASD on a USB hard drive".

• OSX: Mimic Ubuntu IP Masquerading via iptables with ipfw

  - by Dogbert

  Good day, I am attempting to replicate a setup I have between a router and an Ubuntu PC, and have the same setup working on my MacBook (10.6, Snow Leopard). First, I have a router that has a USB port. When I plug it into my Ubuntu PC, it creates an RNDIS connection, allowing me to connect to the router over the USB cable via an IP connection. When I plug it into my computer via USB, it gets assigned an IP address of 172.16.84.1, and a new adapter appears when I type ifconfig. I can then SSH into the device via ssh [email protected]. When I log in to the device, I flush the routes, then create the default route: admin@localhost> route -f admin@localhost> route add default 172.16.84.2 Now, in my Ubuntu machine, I use iptables to enable IP masquerading: root@Valhalla> sudo iptables -t nat -A POSTROUTING -s 172.16.84.2 -j MASQUERADE Once this is all done, the router has internet access over the USB connection to my PC. I am trying to replicate this exact setup on my MacBook now (Snow Leopard), but iptables does not exist for OSX, not even a Macports version exists. I have scoured through other questions on StackOverflow that cover the usage of the ipfw command, which apparently works as a drop-in replacement for iptables. However, the syntax is significantly different, and I'm pretty much lost. Does anyone with some experience with ipfw have some suggestions on how I could accomplish this and create a NAT connection via IP masquerading like I could with my Ubuntu PC? Thank you for your assistance.

• Switch Windows 8 from a hybrid MBR/GPT => GPT only on Macbook Pro Retina

  - by Sid

  I used DiskUtility+Bootcamp Wizard to setup my hard drive for Windows 8 (final MSDN). Somewhere in that process, the Apple tools turned my GPT disk into a hybrid MBR/GPT. All my 4 primary MBR partitions are used up, so when I try turning on Bitlocker in Windows 8, it complains about not finding a System drive. I know on Windows 8 the Bitlocker setup tries to create the 200(?)MB system partition if it's missing. However with all 4 partitions filled I suspect it can't create system drive = it can't find it = throws back an error like "BitLocker Setup could not find a target system drive. You may need to manually prepare your drive for BitLocker". I've already tried disabling hibernation, swap file etc. Now I'm thinking that if I were to get rid of the MBR scheme altogether, perhaps I can be alright within the GPT world without MBR's 4 primary partitions limit. So, how can I get rid of the MBR tables on the hybrid scheme in a manner that still leaves Mac OS and Windows 8 in working conditions? Details: Hardware is the MacbookPro Retina. Primary MBR partitions are consumed as follows: EFI partition HFS+ partition (=encrypted, therefore ="Apple_CoreStorage") HFS+ partition (Recovery partition, contains unencrypted Mac bootloader) NTFS partition (Windows8 all-in-one partition) diskutil list output sid-mbpr:~ sid$ diskutil list /dev/disk0 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *251.0 GB disk0 1: EFI 209.7 MB disk0s1 2: Apple_CoreStorage 160.0 GB disk0s2 3: Apple_Boot Recovery HD 650.0 MB disk0s3 4: Microsoft Basic Data Win8 90.1 GB disk0s4 GPT vs MBR addresses sid-mbpr:~ sid$ sudo gptsync /dev/rdisk0 Password: Current GPT partition table: # Start LBA End LBA Type 1 40 409639 EFI System (FAT) 2 409640 312909639 Unknown 3 312909640 314179175 Mac OS X Boot 4 314179584 490233855 Basic Data Current MBR partition table: # A Start LBA End LBA Type 1 1 409639 ee EFI Protective 2 409640 312909639 ac Apple RAID 3 312909640 314179175 ab Mac OS X Boot 4 * 314179584 490233855 07 NTFS/HPFS Status: GPT partition of type 'Unknown' found, will not touch this disk.** **: Ignore this message, the gptsync tool is old and doesn't understand the UUID for "Apple_CoreStorage" / FileVault2 partitions. Since LBA addresses are alright, safe to ignore this message.

• OS X Client & Ubuntu Server - Best way for client to access files on server?

  - by Camsoft

  I've got a local development web server running Ubuntu. I also have an iMac running OS X 10.6 which I use a client and is my development machine. I'm currently have Samba server installed on my Ubuntu server. I have shares setup for all the website directories. I then use my Mac and Coda to edit the files via their shares. This generally works really well but I noticed that my Mac was writing loads of resource fork ._filename files everywhere. I found out the following about the files: These files are created on volumes that don't natively support full HFS file characteristics (e.g. ufs volumes, Windows fileshares, etc). When a Mac file is copied to such a volume, its data fork is stored under the file's regular name, and the additional HFS information (resource fork, type & creator codes, etc) is stored in a second file (in AppleDouble format), with a name that starts with "._". (These files are, of course, invisible as far as OS-X is concerned, but not to other OS's; this can sometimes be annoying...) Does anyone know of a way of sharing files between a Mac client and a Linux server that is most compantable between the two operation systems? Ideally it needs to support the HFS filesystem so that the resource forks are not created and it also needs to support the permissions between server and client.

• samba share not on network after upgrading to Ubuntu 12.04LTS. [migrated]

  - by Sylvain Huard

  I just upgraded an old Ubuntu box to 12.04LTS (machine named A-Ubuntu). This is an upgrade not a format re-install. All the accounts and config were preserved. The basic setup is a local network with 2 Ubuntu machines (let say A-Ubuntu, B-Ubuntu) and a MAC (C-MAC). Before the upgrade, all of them could see each other by their names not only the IP address. The local network has a D-Link Router where everybody is connected with RJ-45 wired etherenet (not wi-fi). Since the A-Ubuntu upgrade, we can't see this machine name on the Network and its name is not on machine list in the D-Link router anymore. We can see it's IP address only. I can't access A-Ubuntu from the other two by its name but I can ping it with its address (192.168.0.109). From A-Ubuntu, I can connect and see the shared samba folders on B-Ubuntu and C-MAC. But from B-Ubuntu and C-MAc, I can't connect to A-Ubuntu. Correct me if I'm wrong but this tells me that Samba should be fine and the real problem is that A-Ubuntu does not advertise its name on the Network so the D-Link does not have it in its table so nobody else finds it. After a lot of googling, I see that it is the job of avahi and mdns to do so. Those packages are running, I checked multiple config files for samba, avahi, mdns to see as if it is like the examples on the WEB and also similar to what I find on the working B-Ubuntu machine. This is the same. I did multiple service restart with samba, avahi, remove the firewall to make sure it does not block the hostname broadcast. I rebooted multiple time to make sure the update I was making were effective. Still, Can't see the A-Ubuntu name on the network. Any idea what it can be?, Where to look next?

• Synergy, OSX client, Windows 7 server - No mouse on client

  I have the following Synergy setup: +------------++------------++------------++------------+ | Mac || Win 7 || Ubuntu 1 || Ubuntu 2 | |c ||s ||c ||c | +------------++------------++------------++------------+ Mac: OS/X Tiger 10.4.11 (G3) Win 7: Windows 7 Ultimate x64 Ubuntu 1 & Ubuntu 2: Desktop 10.10 Now, everything works nicely between the Win7 server and the two Ubuntu machines. What doesn't work is the Mac. I am running the very latest Synergy (1.4.2, downloaded last night).

I have tried running ktrace on synergyc and examining the dump, and the only clue I found was that it was trying to interact with the AccessibilityAPI which was disabled at first. Enabling Accessibility has had no effect whatsoever (it has only stopped the failure to open /var/db/.AccessibilityAPIEnabled in the ktrace dump) Anyone managed to get this to work in OS/X Tiger yet? I used to run the server on OS/X and have the windows / unix machines as clients, but as my Windows is now a laptop I'd like that to be the server.

• Resolving a BSOD/CPU/GPU issue...

  - by Christian Sciberras

  Hello all, I'm getting a BSOD / system crash (sometimes the PC just quits without a BSOD). Hardware Specifications cpu: i7 920 2666MHz / 8 cores (not OCed afaik) mobo: Asus P6T SE ram: 2x Corsair CM3X2G1333C9 (64bit DDR3 667MHz) gfx: ATI Radeon HD 5970 1GB (XFX HD5970 BE) os: Windows 7 Ultimate 64 bit (legit) All bios, firmware and drivers are all up to date (as of today). Symptoms Sometimes the PC runs smoothly, sometimes I get this BSOD. The BSOD always happens when I'm doing something related to graphics, such as viewing a video or playing a game. I get to know about the imminent BSOD ~10 seconds earlier; the PC starts freezing occasionally but increasing in frequency and length of lag (I noticed processor usage in creased from Process Monitor). I've tweaked BIOS settings occasionally but afaik, it was in vain. A day or so ago, I reset it to factory settings. BSOD contents The computer has rebooted from a bugcheck. The bugcheck was: 0x00000101 (0x0000000000000019, 0x0000000000000000, 0xfffff88001f35180, 0x0000000000000004). 15-12-2010 A fatal hardware error has occurred. Reported by component: Processor Core Error Source: Machine Check Exception Error Type: Internal Timer Error Processor ID: 4 23-12-2010 A fatal hardware error has occurred. Reported by component: Processor Core Error Source: Machine Check Exception Error Type: Internal Timer Error Processor ID: 2 Important The interesting thing is that although the event log (and BSOD screen) blame a "secondary processor", Windows Action Center sometimes blamed the GFX driver (for the same error). Also It is interesting to note that after hibernating my PC, I always get the BSOD.

• Mustek 1200 CP driver SFC4.SYS bluescreens with BAD_POOL_HEADER

  - by Slink84

  I have Windows XP SP2. Recently it started bluescreening right after starting up with 'BAD_POOL_HEADER', 0x00000019 error caused by SFC4.SYS driver. After googling for a while I've found out that this is my Mustek's 1200 CP scanner driver. Booting in safe mode and uninstalling it solved the problem... And created another one: now I can't use my scanner. The weird thing is, that it has been working for a while on this PC without any problems. It all started suddenly, and I can't remember installing anything that might have affected it. Reverting to several earlier system restore points didn't help. I've tried re-installing it from the Mustek website, just in case if my copy got corrupted or infected by a virus, but it did not help - it still bluescreens. Also, I've installed Avast and scanned my PC - there were no viruses found. If anyone had such a problem before or has an idea what might have caused it, please help. ED: @Michael Todd: ...try installing on another PC... I've installed it on my friends PC. He has the same OS version, with the latest updates just like mine (he wasn't too happy, even after I've assured him that it is easy to fix by uninstalling that driver :] ). It worked fine - no bluescreens or whatsoever. So I think I've narrowed it down to either BIOS settings, or some wicked driver conflict. Next thing I'm going to try is to re-install XP, or install windows 7. I'm not too happy with a prospect of mucking about with BIOS settings...

• Printing to a remote printer through the internet

  - by Lock

  I have a remote network (A) that is connected to a head office (B) through a private network. Network A only has 1 PC that requires the connection, and this is into a terminal server at network B. We want to save money by getting rid of the private network as only 1 PC now access it and it seems silly to pay ~$400 per month for something that is accessed by 1 PC. A VPN tunnel is out of the question as the provider wants to charge $600 a month for a VPN tunnel (more than a private network? I might get them to check these numbers). I was thinking of 2 options: 1) VPN client on the PC. This wouldn't cost a thing as we already have VPN users available. 2) Open up a port on the firewall of network B, forwarding to the terminal server. Now the problem is this: On the terminal server, the program that is accessed is for printing labels to the printer that is at network A. The program is setup to send all print jobs to a printer that is setup locally on the terminal server, which has its port mapped to the IP address of the printer that is at network A. If we got rid of the VPN tunnel and used clients/open up firewall port, the printer would no longer be able to find network A, and hence printing would not work. Any ideas to combat this issue? Can the printers at the remote network be setup as internet printers? I've never had any experience with internet printers. Can you open up ports and map to a public static IP address?
