• Fix Linux-made png file for use on Windows

  - by BGM

  There is a particular icon library that I really like. Now, I have downloaded the package that has the png files inside (I know the ico files are there, but I want the png files). However, about my Windows 7 computer tells me that about 1/3 of the png files are corrupt. I usually use XnView to view the files, and it won't display the "corrupt" files. I've tried other editors and viewers and I get the same issue. Now, the png package was originally designed for Linux to be an OS-icon-package for the entire system, so I figure the png files were built in Linux. So, is there a way I can "fix" the "corrupted" png files for my Windows 7 computer? Maybe when the files were created there was some bit that was off-colour or something? Any clues? [edit] I have read in this thread that the "corruption" could happen during the extraction process. I did all the extraction with 7-zip. It was a zip containing a tar. I will try another extractor, but I don't think it will make any difference.

• OpenVPN Server - CPU is pegged out

  - by ericl42

  Hello, I am configuring OpenVPN to act as a SSL tunnel for a remote location. I have OpenVPN1 at our current location acting as a server then OpenVPN2 at the other location that is acting as a client but is also acting as a DHCP server to machines behind it so they are basically connected to the local LAN. Everything is set up fine and I can talk from location A to location B with no problems like everyone is local. I am however having some performance issues. OpenVPN1 CPU is pegged to 100% the entire time I am copying or doing any type of activity through the tunnel. I expect some CPU usage going up but nothing like this. It's really killing my performance. OpenVPN1 is running in ESX right now with 2 gig RAM and 4 procs with unlimited bursting capacity. I am using AES-192 encryption with a 1024 key. Any idea how I can get my CPU down on OpenVPN1 and my download/upload speeds higher between the tunnel? Thanks. edit: Turning down the logging helped boost the throughput a little bit, but I am still fairly shy of where I believe I should be. Also I am still maxed out on the CPU. Does anyone have any ideas? I am really stuck on this. Thanks.

• Sandra reports my CPU as "Engineering Sample", how can I be sure this is correct?

  - by stevenvh

  I ran SiSoftware's Sandra on my new PC, and for my CPU it reports: Generation : G8 / T29 Name : TN0 (Trinity) FX/Opteron 32nm (ES) Revision/Stepping : 0 : 10 / 1 Stepping Mask : TN-A1 Microcode : MU6F10010F The (ES) is a well-known code in product development, meaning "Engineering Sample". Those are beta versions of the CPU, which still may contain some bugs, or even have features switches off. I contacted both the PC's manufacturer Medion as well as AMD about this. I had to downvote the Medion helpdesk here. The person I talked to boldly said Sandra was wrong (without knowing how Sandra got this information; he didn't even know the software), and used the word "impossible". His conclusion was "We’re not taking this in consideration for service”. Right. So, if you like Medion for their good prices, but like good support even better, you may consider buying your PC elsewhere. AMD was more helpful, but wanted to be sure before replacing the part (which I find reasonable). They suggested that I dismount the cooler from the CPU to check what was printed on it to be sure. I'm a bit reluctant here: I would have to wipe the thermal paste from the CPU, and won't know for sure my cooling will still be OK afterwards. Questions Has anybody actually found a confirmed ES CPU in her PC? Is anybody aware of Sandra erroneously reporting CPUs as Engineering Samples? How can you tell an ES, apart from the print on the package? Shouldn't Stepping Mask identify the CPU uniquely?

• RAM ok in memtest86+ == RAM ok after wake from sleep?

  - by twon33

  I have a Windows XP (32-bit) system that appears stable in normal operation, but was repeatably freezing (hard lock, no BSOD) a minute or so after waking from S3 sleep. Some Googling against the motherboard model and memory manufacturer suggested that I might need to bump up the memory voltage, so I tried it and it now seems to resume without freezing. However, I don't really trust it and I'd like to validate that it's actually stable, especially after resuming from sleep. I've run Prime95 for a few hours with no issues, and am planning an overnight run of Memtest86+, which I expect to pass because the system has been solid whenever I've run it without putting it to sleep. Does something like Memtest86+ exist that actually invokes S3 sleep during operation? Clearly it would need an operator to wake the computer to resume testing, but I don't think I've ever heard of a memory test tool that can do this. Alternately, am I wasting my time? Should a clean bill of health from Memtest86+ indicate stability regardless of whether sleep is involved, or, conversely, does my original problem indicate that Memtest86+ would have failed eventually with the stock voltage if I'd run it, sleep or not?

• Why can't I update Adobe Creative Suite?

  - by Lynda

  I am attempting to check for updates using the Adobe Application Manager on Windows 8 and I get this error: The update server is not responding. The server might be offline temporarily, or the Internet or firewall settings may be incorrect. I have seen this error before on Windows 7 and remembered that I needed to disable the Microsoft Virtual WiFi Miniport Adapter. I navigated to the correct place but the Miniport Adapter was not there. After a bit of searching across several forums I saw a recommendation to change <logLevel>2</logLevel> to <logLevel>10</logLevel>. I attempted that and again it still did not work. I have also tried disabling my anti-virus protection and disabling Windows Firewall. Neither worked. I am not sure what else to try or do at this point. Are there any other recommendations to solve this issue? Notes: I am running Windows 8 Pro using the Creative Cloud Version of CS6. I check for updates by choosing Help Updates from within any Adobe Application This issue was not present in Windows 7 before I upgraded to Windows 8 I originally posted this question on the Adobe Forums and received no help there.

• IIS 7.5 Warning : Cannot verify access to the path

  - by Mostafa

  I'm newbie in IIS 7.5 , Before this I used to run ASP.NET Website under IIS 5 , That was too easy . I'm trying to run a very simple asp.net website ( just created a new website from VS 2010 targeted in .net 3.5) in IIS 7.5.7600 on windows 7 Ultimate 64 bit . While adding application , during Test Setting i receive one warning that says : The server is configured to use pass-through authentication with a built-in account to access the specified physical path. However, IIS Manager cannot verify whether the built-in account has access. Make sure that the application pool identity has Read access to the physical path. If this server is joined to a domain, and the application pool identity is NetworkService or LocalSystem, verify that \$ has Read access to the physical path. Then test these settings again But I don't know how to make sure application pool identity has read access to the physical path ? I'm wondering if there is any step by step article or some thing that show me the walk-though for running a simple asp.net website on IIS 7.5? I appreciate any help .

• Some guest networking and VMware Tools functionality broken with Sprint SmartView on the host

  - by Mads

  Using VMware Workstation 6.5.3 on Vista 64-bit. I started having problems with VMware networking about 6 months ago after upgrades to Sprint SmartView. I did not have problems previously, but I don't know if that is because I was lucky. The main symptoms of the problem when SmartView is installed are: I can no longer drag files from the host to copy them to the guest. When they are dragged, the disallowed cursor (the circle with a slash) shows in the guest. If I try to enable shared folders in the guest while it is running, I will not be able to see the shared files and will be informed that networking is not working. I can still ping guests from the host and I can still access network services via NAT most of the time when connected via my USB broadband adapter. When I configure shared folders so they are "always enabled" (with a mapped drive), I can access files on the via the mapped folders. I can also copy the file on the host and then paste it in the guest, as was suggested in some other threads concerning drag-and-drop problems that I found. The VMware Tools icon is showing in all cases and I don't see any obvious errors in the host's event viewer. If I uninstall SmartView, the problems disappear. If SmartView (current version is 2.28.0082) is reinstalled I will experience the same problems. I have tried uninstalling/reinstalling VMware and SmartView in various ways but it appears tha these problems are consistent when SmartView is installed (not just when it is running or connected, but when it is present on the system). I'm wondering if this is a combination of software (WS 6.5.3, Vista64, and SmartView) that works for other people, which would indicate a problem that is peculiar to my configuration.

• Dell Studio 1555 not starting up

  - by Abhishek

  This is a 3-year-old laptop. I never had a big problem with it until now. I updated Kubuntu the night before yesterday. And Firefox got updated to version 18 and a few other related packages got updated. Then I shut down the laptop and restarted it, but it failed to start. I could hear the fan and the hard disk and the optical disk drive initialize. And the power button also lighted up. But there was no video - no POST or BIOS menu. I even opened the laptop up to the point when only the motherboard was the only thing attached to the base cover. I took it to the technician this evening. He checked it casually, and said that it might be a motherboard problem and will cost quite a bit to fix. Though he was not sure and said that he will give me a call after confirming the problem. Has anyone else had the same problem? What was it and what was the fix?

• Cluster FIle System

  - by Ben

  We are looking for to choose a clustered file system for our in house appplication. Let me first highlight my requirement. we have a storage and 2 servers at present.We get the data files from remote servers to our server and on both servers we are running our application to access those data and make a final result as per our requirements. In future may be after 3-4 months, we can add another servers in current cluster pool to handle more data load from remote location data senders. So my requirement is that to integrate same storage partition on 2-3 servers , it might be 4-5 more servers in future, My application read data from storage partition and write back to storage partition. Is there any bottleneck / limitation from RHCS , GFS2 or anything.? We are new with RHCS + GFS and all. Can we have any other better approach or someway to deal with our requirement light way? what is the best OS version for this ? how's RHEL 6.4 64 bit ? please share some case study or some gudie reference as per past experiences with such environnmnets Regards, Ben

• Openldap startup problems after upgrade

  I am trying to syncrhonize a ldap slave and master server. The master server is using openldap 2.3.43-12 and the slave server is using openldap 2.4.23.

• Bridging my laptop's wireless and wired adaptors

  - by stacey.richards

  I would like to be able to connect a desktop computer that does not have a wireless adapter to my wireless network. I could just run a network cable from my ADSL/wireless router to the desktop computer but sometimes this is not practical. What I would really like to do is bridge my laptop's wireless and wired adapters in such a way that I can run a network cable from my laptop to a switch and another network cable from the switch to a desktop computer so that the desktop computer can access the Internet through my ADSL/wireless router via my latop: +--------------------+ |ADSL/wireless router| +--------------------+ | +-------------------------+ |laptop's wireless adaptor| | | |laptop's wired adaptor | +-------------------------+ | +------+ |switch| +------+ | +-----------------------+ |desktop's wired adapter| +-----------------------+ A bit of Googling suggests that I can do this by bridging my laptop's wireless and wired adapters. In Windows XP's Network Connections I select both the Local Area Connection and the Wireless Network Connection, right click and select Bridge Connections. From what I gather, this (layer 2?) bridge will examine the MAC address of traffic coming from the wireless network and pass it through to the wired network if it suspects that a network adapter with that MAC address may be on the wired side, and vice-versa. If this is the case, I would assume that when the desktop computer attempts to get an IP address from a DHCP server (which is running on the ADSL/wireless router), it would send a DHCP broadcast packet which would pass through the laptop's bridge to the router and the reply would return through the laptop's bridge back to the desktop. This doesn't happen. With some more Googling I find some instruction how this can be done with Linux. I reboot to Ubuntu 9.10 and type the following: sudo apt-get install bridge-utils sudo brctl addbr br0 sudo brctl addif br0 wlan0 sudo brctl addif br0 eth0 sudo ipconfig wlan0 0.0.0.0 sudo ipconfig eth0 0.0.0.0 Once again, the desktop cannot reach the ADSL/wireless router. I suspect that I'm missing some simple important step. Can anyone shed some light on this for me?

• Wireless connection drops when wired computer starts a game.

  - by Skadlig

  Starting this week I have had a strange problem on my network. Some background of my setup: Internet is provided by a adsl-modem. A D-link Dir-600 router is hooked up to to adsl-modem. My computer is hooked up to the router using a cat-5 cable. My wife's computer is hooked up using a wireless usb dongle, TP-Link TL-WN821N. Both computers use windows 7 64-bit home premium. Up until this week everything was normal, we could for instance play Dungeons & Dragons Online together without any network issues. Now every time I start DDO or any other network game, for instance L4D, the whole wireless network drops. I have confirmed that it's not just her computer using an Samsung Galaxy Spica android phone. Shutting down the game on my end restores the wireless connection automagicly. My wife can start DDO without the net dropping but if I plug in a wireless network card in my computer and start up the game the connection drops. So it seems like something my computer, and my computer only, does when starting a game makes the wireless connection write a sad note and kill it self but for the life of me I can't figure out what that might be. I could hook her computer up using cat-5 but I would prefer not to do that. Does anyone have any suggestions as to what the problem might be, what I can do to fix it or what I should do to get more data regarding what is happening?

• Coming from Win XP to 7 and having new accessibility software problems

  - by Anonymous Jones

  I just switched from Windows XP Pro SP3 (32bit) to Windows 7 Ultimate (32bit) on a new PC. Now, both the new onscreen keyboard and a utility for sending mouse clicks are being problematic. The problem with 7's OSK is that some things I type only work intermittently or just dodgily. Like Alt+Tab with multiple Tabs, other Alt/Ctrl/Shift/Win key combinations, and the context menu key. Sometimes apps will not take focus for input at all. I use the OSK it in 'hover' mode, on 0,5 seconds. The clicking tool is Point-N-Click, which sends clicks when I dwell anywhere for 1.25 seconds with the mouse pointer. http://www.polital.com/pnc/ The problem with it is that sometimes it fails to click. Most often this happens in some of the control panel sections, on the taskbar, and when UAC pops up. It seems to occur in conjunction with OSK usage a bit too, I think. I'm using an Administrator account. DEP and UAC settings are default. What can I do to fix or work around either of these problems? I'm disabled so this really is killing usability.

• Drobo-like linux file server - how do I do it?

  - by John Hunt

  I've been pondering for a long time about how I can set up a server which operates much like the Drobo storage thing. The reasons I don't actually want a drobo is because I've heard scare stories, plus I'd like to do this on the cheap. So ideally I'm looking for something like lvm so I can create a logical volume that spans many hard disks of varying sizes... obviously that only offers redundancy if I put the LV on a raid array (as far as I know..) I have however been reading about technologies such as Microsoft's drive extender which duplicates files at the filesystem level and makes sure that the mirrored files are on a different phyiscal disk.. does anyone know or recommend a filesystem or method like this as it'll hopefully make much better use of the space available than raid ever could. Performance isn't an issue, I'd just really like to make the most of the hard disks I have lying around whilst having a bit of redundancy incase a disk dies. I understand full well that this is no replacement for a backup, but I'll only be storing files of medium importance and using the nas itself as a backup of my main pc and other systems. Thanks in advance! I'm hoping zfs or btrfs or something can do something clever for me :)

• Creating an ec2 image on amazon fails at mkfs.ext3

  I'm trying to create an image of my ec2 instance in Amazon's cloud. It's been a bit of an adventure so far. I did manage to install Amazon's ec2-api-tools, which was harder than it seemed like it should have been. Then I ran: ec2-bundle-vol -d /mnt -k pk-{key}.pem -c cert-{cert}.pem -u {uid} -s 1536 Which returned: Copying / into the image file /mnt/image...

But ec2-bundle-vol doesn't seem to take in a volume name as an argument, and the docs (http://docs.amazonwebservices.com/AmazonEC2/gsg/2006-06-26/creating-an-image.html) don't seem to think one should be needed. Certainly their sample command: # ec2-bundle-vol -d /mnt -k ~root/pk-HKZYKTAIG2ECMXYIBH3HXV4ZBZQ55CLO.pem -u 495219933132 -s 1536 doesn't specify anything. So... any help? What am I missing?

• How to make a Linux software RAID1 detect disc corruption?

  - by Paul

  This is one of the nightmare days: A virtualized server running on a Linux SW-RAID1 runs a VM that exhibits random segfaults in seemingly random codechunks. While debugging I find that a file gives different md5sums on each and every run. Digging deeper I find this: The raw disc partitions that make up the RAID1 mirror contain 2 bit-differences and ca. 9 sectors are completely empty on one disc and filled with data on the other disc. Obviously Linux gives back a sector from a undeterministically chosen disc of the mirror set. So sometimes the same sector is returned OK, sometimes the corrupted is given back. The docs say: RAID cannot and is not supposed to guard against data corruption on the media. Therefore, it doesn't make any sense either, to purposely corrupt data (using dd for example) on a disk to see how the RAID system will handle that. It is most likely (unless you corrupt the RAID superblock) that the RAID layer will never find out about the corruption, but your filesystem on the RAID device will be corrupted. Thanks. That will help me sleep. :-/ Is there a way to have Linux at least detect this corruption by using sector checksumming or something like that? Would this be detected in a RAID5 setup? Is this the moment I wish I used ZFS or btrfs (once it becomes usable without uber-admin capabilities)?

• MySQL Config on Large Machine

  - by Jonathon

  We have a Windows 2003 Enterprise Edition server (64bit) running only MySQL 5.1.45 64-bit. It has 16G RAM and 10T of hard-drive space in RAID 10. We are having horrible performance from mysqld (85-100% CPU utilization). We were running a smaller machine with better performance, so I am assuming our my.ini file is not correct for our current machine. The my.ini file is as follows: [client] port=3306 [mysql] default-character-set=latin1 [mysqld] port=3306 basedir="D:/MySQL/" datadir="D:/MySQL/data" default-character-set=latin1 default-storage-engine=MYISAM sql-mode="" skip-innodb skip-locking max_allowed_packet = 1M max_connections=800 myisam_max_sort_file_size=5G myisam_sort_buffer_size=500M table_open_cache = 512 table_cache=8000 tmp_table_size=30M query_cache_size=50M thread_cache_size=128 key_buffer_size=3072M read_buffer_size=2M read_rnd_buffer_size=16M sort_buffer_size=2M #replication settings (this is the master) log-bin=log server-id = 1 Does anyone see anything wrong with this setup? For a machine with this much RAM, why in the world would mysqld eat up so much CPU? I know we can optimize some queries, etc., but it did run okay on a smaller machine, so I am pretty sure it is the config. Thanks in advance for any help.

• Cannot set video resolution above 640x480 after installing Windows XP SP2

  - by waanders

  I've installed Windows XP SP2 on a computer (there was not SP at all). Now the display settings are set back to 640x480 and 4 bits colors. And I can't change it, it's the only option in Settings tab of the Display dialog of Windows. The screen look awful now, how can I solve this problem? UPDATE: Seems to be a problem with the video driver (thanks @Karan and @Hennes). I did run Speccy (PC-Wizard freezes the computer) and this is a part of the log file: Summary Operating System Microsoft Windows XP Professional 32-bit SP3 CPU Intel Celeron Willamette 0.18um Technology RAM 512 MB DDR @ 133MHz (2.5-3-3-6) Motherboard COMPAQ 0838h (FC-478) Graphics Standard Monitor (640x480@1Hz) Hard Drives 19.0GB Maxtor 2B020H1 (PATA) Optical Drives No optical disk drives detected Audio No audio card detected ...

• What is easiest no fail way to publish asp.net app?

  - by Maestro1024

  What is easiest no fail way to publish asp.net app? Sorry a bit of an open ended question but I am having issues deploying an asp.net report project and any solution to get the site up is fine. I am running Win7/SQL 2008 and want to publish a asp.net report site that I created in VS 2008. Website launches when I run in debug in Visual studio but I want to publish the site so that it can be seen on the LAN. I published the files off to a folder and started up the IIS manager and added a new site and pointed to that folder. Set the permission on the folder to share to everyone. However when I go to the DNS name I put in for the website it does not launch. Any ideas on this? I see websites out there talking about a web sharing tab on the folder properties but I do not see that when I go to folders. Why might that be? Another avenue I have not pursued yet is publishing directly to a website. Has anyone tried that? Is that better or worse than publishing to filesystem?

• Installing Windows 7 over PXE, preferably with domain autojoin

  - by Ivan Vucica

  At an educational non-profit, I've inherited a previously set-up Windows domain that, after the first reinstall of the machines, we ended up not using by simply not joining machines back into the domain. Over last summer, before the annual reinstall for shipping machines to the summer school, I toyed with the idea of installing Windows 7 over network, instead of just imaging the machines. It took a bit longer than I expected to figure out the basics; honestly, I expected that Windows would be more friendly for PXE installation out of the box. What I'm interested in is best practices for installing Windows 7 over PXE with domain autojoin. I'd love it if the whole setup could optionally be hosted on a UNIX based system as well. I've had some success by preparing an ISO using Windows Deployment Kit, and loading the ISO into memory. This was needed since I wanted a menu, and I think I couldn't get PXELINUX to chainload into Windows' bootloader. Unfortunately, I couldn't figure out much about customization of the Windows setup in that timeframe nor could I get Samba to work properly; studying the stuff ended up being too lengthy, especially the portion where I edited a disk image on Windows and copied it outside. WDK didn't make things easier by mounting the disk image into RAM, and writing it in its entirety when done with it, making me a very sad boy. I've recently found a different approach, too, that appears to be closer to Microsoft's original idea for netboot deployment and does not involve ISOs. So my question boils down to the following. What exact approach do you use for netbooting Windows 7 setup? How can Windows 7 setup be best customized to be completely unattended, including installation on specific system partition and not destroying the data partition, creation of passworded admin and default user, choice of MAC-address-based hostname, and joining a domain? As much details as possible for everyone's future reference would be appreciated. WDS isn't a bad choice, but if a Linux-based install can be used, that'd be better.

• Backup plan for linux webserver in small business?

  - by radman

  Hi, I am currently in the process of writing a backup plan for the webserver in use by my business. I am very new to this area and have a few ideas about how things should work but am unsure of what tools to use and what sort of restore process is appropriate. I'm looking for something relatively simplistic and it doesn't have to be 100% paranoid just enough to give me a reliable backup. Speed is not of the essence and there is not going to be a live fallback in place. The backup will be onto a single hdd that will be stored onsite (no option for offsite as yet). Backups will be taking place weekly. I am constrained by both time and money which is why I'm aiming for a good enough solution. Is taking an image of the webserver system drive periodically and using that as the backup appropriate? Should I be testing that the backups restore correctly every time that I perform one? This is a bit broad but what setup would you use if you were in my place, given the services I am running? Should I add additonal machines and split the services? Any advice is much appreciated!

• What options to use for Accurate bacula backup?

  - by Kiss Stefan

  It's actually 2 question in one. First is a bit more theoretically. So when specifying accurate options how does bacula figure out if a file needs to be backed up ? it's a simple AND ? As in if the options are Accurate = sm5 bacula will not backup the file if ((size = old size) AND (modtime = old modtime) AND (md5 = old md5)) Is that correct ? Do any of the options take precedence ? as in would be a file skipped if modif time is diffreent but it has the same md5sum ? Are there any implied options that you cannot ignore ? Practical case, ( bacula 5.0.1 ) I have to back-up a svn repo, in order to be able to make incremental backups as simple as posible i am hotcopying (client run before) it to another location, that bacula will backup ( then delete it with client run after). Now in the fileset i have Accurate = spnd5 This should tell bacula to take into consideration size , permission bits number of links , decreases in size and md5sum. However , an incremental is also including a full copy of the svn. What am i doing wrong ? it seems that it takes into account creation time even tho i have not specified it.
