• Are there any other causes of this error that are NOT related to initial setup?

  - by LordScree

  I'm trying to diagnose an issue at a customer site. They are receiving the following error: A network-related or instance-specific error occurred while establishing a connection to SQL Server I've seen this a few times, but only during the initial setup - it's often caused by one of the following: The database server is turned off The network connection between the database server and the application is closed or somehow blocked (e.g. a firewall) The SQL Server instance is not set up to receive remote connections from the application server (e.g. TCP is turned off, remote connections are disabled, or the "SQL Server Browser" service is stopped/disabled) However, if I assume that no configuration changes have been made, I'm trying to postulate on what the reason might be for getting this error at a random point after the initial setup. My initial thought is: SQL Server machine has run out of resources (e.g. RAM) and is unable to accept new requests from the application server Is this a valid theory? What other possible causes are there of this error that are not related to the initial setup of the server / application connection? Or is it simply impossible that this error could occur without a configuration change having been made (either on the SQL Server side, application side, or somewhere in-between (network))? NOTE: I believe this question differs from the plethora of questions related to this error message because the application and server have been talking to each other quite happily until now (most, if not all, other questions seem to relate to initial setup).

• Mysterious swap usage on EC2

  - by rusty

  We're in the middle of a project to move our infrastructure from a co-lo situation into Amazon EC2 and we've noticed some weird memory characteristics of the processes in our setup. Without going into too much detail about the specifics of our processes, we've noticed that on our EC2 instances "top" will show processes using a lot of swap space -- in fact, much greater than the amount of available swap or (if you add it all up) more than the available disk. Here's a sample top output: Mem: 7136868k total, 5272300k used, 1864568k free, 256876k buffers Swap: 1048572k total, 0k used, 1048572k free, 2526504k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ SWAP COMMAND 4121 jboss 20 0 5913m 603m 14m S 0.7 8.7 3:59.90 5.2g java 22730 root 20 0 2394m 4012 1976 S 2.0 0.1 4:20.57 2.3g PassengerHelper 20564 rails 20 0 2539m 220m 9828 S 0.3 3.2 0:23.58 2.3g java 1423 nscd 20 0 877m 1464 972 S 0.0 0.0 0:03.89 876m nscd You can see, for instance, that jboss is reportedly using 5.2 gigs of swap space which is definitely impossible since there's only 1G allocated and none is being used (probably because there's still 1.8G of RAM free). And here's the results of uname -a: Linux xxx.yyy.zzz 2.6.35.14-106.53.amzn1.x86_64 #1 SMP Fri Jan 6 16:20:10 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux We're running an AMI based off of the default Amazon Linux AMI (Amazon Linux AMI release 2011.09, so some RHEL5 and RHEL 6) with not too many customizations and definitely no kernel-level customizations. Something here tells me that on this particular kernel/distribution, the reporting of swap or maybe even total memory usage isn't what it appears to be... Any help would be appreciated!

• Dual boot Windows 8 and Ubuntu 12.10 across a reboot

  - by AK4749

  My Setup: I have two separate SSDs, and each contains an independently bootable OS - W8 and U12.10. From my extremely limited knowledge, this means each has a functioning EFI partition(?). My default boot order (GA-Z68XP-UD3P mobo with UEFI firmware update) boots the UEFI partition containing windows first, but if I enter the BIOS I can select the "ubuntu" entry to successfully boot ubuntu. Both drives are GPT, and are EFI boots. What I want to do: Reboot Windows 8, re-enter W8 (this is happening now due to the default boot order). What I want to change, however, is to boot into Ubuntu if i reboot from ubuntu. Essentially, I would like to work within one OS unless I consciously choose otherwise. Normally, I would not even ask to something I thought was impossible, but... Why I think this is possible: When trying EasyBCD to add ubuntu to the W8 UEFI bootloader, I noticed an "iReboot" addon or something that allows you to select which OS to boot into from within the OS. Note that I ended up not using the NeoGrub entry to chain Ubuntu off the W8 bootloader because I couldn't get much help with it. Is this possible? Have I had too much coffee and gone insane? Thank you all for your time, AK

• DBCC CHECKDB fails and quits job, ambiguous error message.

  - by ddono25

  I received a notice that one of our servers' DBCC CHECKDB for all databases has been failing the past four times it has been run. We don't have any data prior to that, but it doesn't look like it has been succeeding for awhile. There are no errors in the log file only: DBCC results for 'sys.sysxmlfacet'. [SQLSTATE 01000] Msg 0, Sev 0, State 1: Unspecified error occurred on SQL Server. Connection may have been terminated by the server. [SQLSTATE HY000] There are 112 rows in 1 pages for object "sys.sysxmlfacet". [SQLSTATE 01000] I ran a DBCC CHECKDB using sp_MSForEachDB to get more accurate results and had the same error on the same DB but at a separate point: DBCC results for 'NameValuePair_Greek_CI_AS'. [SQLSTATE 01000] Msg 0, Sev 0, State 1: Unspecified error occurred on SQL Server. Connection may have been terminated by the server. [SQLSTATE HY000] There are 0 rows in 0 pages for object "NameValuePair_Greek_CI_AS". [SQLSTATE 01000] Also, the error-log states that the DBCC completed without errors for this database. I can't figure out how to track down this ambiguous issue that only happens on this database out of the dozens on this server. Any help is appreciated!

• Network Sniffing and Hubs

  - by Chris_K

  This will likely seem naive to the experts... but it has been on my mind lately. For years I've been using ntop and a cheap 4 port hub to sniff client networks to determine who's doing what -- and how much. Great way to see what's going on when they call and say "Geeze, the network seems really slow today." No need to bring in a managed switch (or access the existing one) and no need to configure spanning or mirroring. I just drop in the hub inline where I want to measure. Lately I noticed it is just about impossible to buy a real honest-to-goodness hub anymore. While looking for a new one, I had someone tell me that I should be sure to get a full-duplex hub or I'd only be seeing half the traffic when I monitor. Really? I've been using a crusty old Netgear DS104 all this time. No clue if it is half or FD. Have I really been understating my measurements? I'm just not bright enough about the physical layer to really know... Side note: Just ordered a Dualcomm Ethernet Switch TAP as a hub replacement. Seems like a nifty gadget. Any notes or tips about it would be welcome in the comments :-)

• Is it possible to command a common router without using the web interface?

  - by MDeSchaepmeester

  Some background The internet arrangement in my student home is really weird. There is one ethernet outlet and several wifi hotspots. Either way requires a login through a web site to get internet access. This is annoying as each device needs to login seperately and with a PS3 for example, it is impossible to get connected at all since the web login procedure doesn't work. Therefore I have installed a D-Link DIR-635 router which is connected to the ethernet outlet. It has DHCP enabled so it uses NAT, but whatever it is connected to also uses NAT and I've read this should not work. A fellow student tried it with an Apple Airport but that keeps giving errors related to NAT after NAT. Anyway my setup does work so bonus points if you can clarify this. I need to login to the web site I mentioned earlier with any device, after which all devices in my LAN have connectivity. This is great. Except... In short From time to time, I lose internet connectivity and my D-Link DIR-635 router needs to do a DHCP renew. I can do this via the web interface but my life would be easier if I could just run a cmd file which tells my router to do this without all the hassle. This would setup a connection to my router and execute the proper command. I have tried googling but couldn't find much helpful stuff.

• OpenVZ container is running but does not show in vzlist nor can I find the private/conf files for the container

  - by Kakeakeai

  I was creating a new OpenVZ container on one of our VPS Nodes while the power went out for that machine. After bringing the machine back online I could no longer access the container CTID=101. I could not destroy it using "vzctl destroy 101", I can not enter or control it, and "vzlist -a" does NOT display any containers at all (this was a fresh node and the first container was being created). I decided to create a new container at this point assuming that the old container just was not saved for some reason. However when I go to add the ip/host to the new container I get a warning that the IP is already in use. After doing a ping to the IP I realized there was a machine on that IP. I SSH into the machine and discover it is the OLD container that some how is orphaned. I can not find it on the filesystem, I can not find it using VZ commands, and It is set to start on Node boot so it is impossible to shutdown (even ssh in and typing the "shutdown now" command just reboots the container not shut it down). Is this a flaw in OpenVZ or am I missing something? I have all the outputs and logs if needed. Thank you all so much in advance.

• Best solution top keep data secure

  - by mrwooster

  What is the simplest and most elegant way of storing a small amount of data in a reasonably secure way? I am not looking for ridiculous levels of advanced encryption (AES-256 is more than enough) and I am only looking to encrypt a small number of files. The files I wish to encrypt are mostly comprised of password lists and SSH keys for servers. Unfortunately it is impossible to keep track of ever changing passwords for my servers (and SSH keys) and so need to keep a list of the passwords. Obviously this list needs to be secure, and also portable (I work from multiple locations). At the moment, I use a 10MB encrypted disk image on my mac (std .dmg AES-256) and just mount it whenever I need access to the data. To my knowledge this is very secure and I am very happy using it. However, the data is not very portable. I would like to be able to access my data from other machines (especially ones running linux), and I am aware that there are quite a few issues trying to mount an encrypted .dmg on linux. An alternative I have considered is to create a tar archive containing the files and use gpg --symmetric to encrypt it, but this is not a very elegant solution as it requires gpg to be installed on every system. So, what over solutions exist, and which ones would you consider to be the most elegant? Ty

• Centralized backup method recommendation for SMEs with various OSes

  - by Akinator

  Hi I was wondering what in your opinion is the "best" method for having "everything" backed-up in the following situation. We are a SMEs with 10 computers in total. Three of those computers are MACs The rest are windows (1 vista, 4 win7 and 2 XPs) I'm very open to what the method should be but you should also consider the follwing: Very limited resources Quite "small" bandwidth (4 MBs for all (download) 0.4 MBs (upload, yep, thats it)- though this might get, a little bit better) One of the main thing to back up would be the mails, considerations: All windows computers use outlook, mainly 2003 There is one mac that uses outlook too (for mac of course - not 2011 yet) We also have to backup the files: Not a huge amount Very few very big files Very organizes (by machine) What I would like is to hear your opinions as to which would be the best method (or combination of methods - preferably one of course) considering. We are not sure what do we need and I'm open to suggestions, though an online (cloud based applications) would be great, remember the the bandwidth is unbearable. Last think to consider, it that we would like to do weekly updates (unless the method is very easy of course). Thanks in advance!! I tried to be as specific as possible, but if anything is needed I'll gladly update, please ask for any clarification needed! Please avoid any answers like upgrade all to windows 7 and throw away your macs :) our's may not be an ideal situation, but it is what it is, and right now, it would be impossible for us to change it for a lot of circumstances.

• Imported Hyper-V VM hangs

  - by BParker

  I have a pair of Hyper-V servers (Server 2008 R2 + Hyper-V role). I have duplicated one VM (exported from the first Hyper-V server to the Second) which seems to keep hanging. The VM is running XP SP3, and has the Virtual Additions installed. The first version runs fine, cpu normally around 0%-2% when idle and responds happily. The second version runs very poorly, and keeps running at an idle of around 8% cpu. I have checked the VM with Process Explorer, and the Idle process is (as expected) taking nearly all the cpu time, but what it's not using doesn't seem to show up in any other process. For example at one point idle dipped to 73%, but i could only account for anoth 4.5% in other processes. After some time (around 1-2 days) the VM seems to become so unresponsive, the only way to resurect it is to power-off the VM and reboot (shutdown via the Hyper- V console of via the VM seems to be impossible). Does anyone have any suggestions on how to trace the source of the problem? Thanks

• Urgent: how to deny read access to a ExecCGI directory

  - by Malvolio

  First, I can't believe that that isn't the default behavior. Second, yikes! I don't know how long my code's been hanging out there, with all sort of cool secret stuff, just waiting for some hacker who knows Apache better than I do. EDIT (and apology) Well, this is sort of embarrassing. Here's what happened: We had some Python scripts available to the web, at /aux/file.py, which were not surprisingly at /var/www/http/aux . Separately, we were running an app server and Apache proxies through at /servlets/. A contractor had constructed the WAR file by bundling up all the generated files including the Python files (which are in a directory also called aux, not surprisingly), so if you typed in /servlets/aux/file.py, the web-server would ask the app-server for it and the app-server would just supply the file. It was the latter URL that this morning I happened to type in by accident and lo, the source appeared. Until I realized the shear unlikelihood of what I had done, the situation was rating about 8.3 on the sphincter scale. After a tense half-hour or so I realized that it had nothing to do with the CGI (and that serving files that were also executable would be not only foolish but also impossible), and was able to address the real problems. So -- sorry, everybody. Let the scorn-fest commence.

• ASA 5505 VPN setup. VPN works but still unable to reach devices in the inside network.

  - by chickenloop

  I've setup a Remote Access VPN on my Cisco ASA 5505. I'm able to connect to my ASA via my phone or the Cisco client, but I'm unable to reach devices in my inside LAN when connected via VPN. The setup is the following: Inside Network : 10.0.0.0/24 VPN_POOL: 172.16.0.0/24 Outside Network: 192.168.1.0/24 ASA is not the perimeter router, there is another device on the 192.168.1.0/24 network which is connected to my cable provider. Obviously UDP port 500 and 4500 are forwarded to the ASA's outside interface. Everything works perfectly, besides the VPN stuff. Config: interface Vlan1 nameif inside security-level 100 ip address 10.0.0.254 255.255.255.0 interface Vlan2 description Outside Interface nameif outside security-level 0 address 192.168.1.254 255.255.255.0 object network VPNPOOL subnet 172.16.0.0 255.255.255.0 object network INSIDE_LAN subnet 10.0.0.0 255.255.255.0 Then the exempt NAT rule. nat (inside,outside) source static INSIDE_LAN INSIDE_LAN destination static VPNPOOL VPNPOOL I don't think that the problem is with the VPN config, as I can successfully establish the VPN connection, but just in case I post it here: group-policy ZSOCA_ASA internal group-policy ZSOCA_ASA attributes vpn-tunnel-protocol ikev1 split-tunnel-policy tunnelspecified split-tunnel-network-list value Split-Tunnel default-domain value default.domain.invalid tunnel-group ZSOCA_ASA type remote-access tunnel-group ZSOCA_ASA general-attributes address-pool VPNPOOL default-group-policy ZSOCA_ASA tunnel-group ZSOCA_ASA ipsec-attributes ikev1 pre-shared-key ***** Any ideas are welcome.

• Can I have a single solid state drive and a RAID array on the same machine? [closed]

  - by jaminto

  Hi- To summarize, i'm looking to use a single solid state drive as my primary drive, and two conventional sata drives in a RAID 1 configuration for data. I am trying to install 64-bit Windows 7 onto this configuration. Is this possible? Here are the details: I built a desktop that has been running 64-bit Vista on two 500Gb in a RAID 1 array for a few years. I just purchased an Intel X25-M 80Gb Sata Solid-State Drive, and was planning on using this a my primary drive, and keeping the RAID 1 array as my data drive. I added the SSD drive and in the RAID setup, configured it as a RAID 0 array of only one disk. Then, I tried to do a clean install of windows 7 64-bit, but got stuck in the "Missing driver for CD/DVD drive" black hole of selecting driver files and Windows telling me that i don't have the appropriate driver for my hardware. The missing hardware is NOT a CD/DVD drive, since i'm installing off of my only CD/DVD drive. Plus at one point i was able to point it at a driver for my raid controller, and then my hard drives magically showed up as browsable sources for finding drivers for some other unnamed device that setup couldn't recognize. After a few hours of trying drivers (this was a very slow process) i decided to reboot and look at the BIOS settings. I'm using an ASUS M2A-VM motherboard which has an ATI SB600 RAID controller on board. I switched the "On board SATA Type" setting from "SATA" to "AHCI" thinking that since AHCI is an Intel thing, this would help. Unfortunately, this abandoned my RAID configuration, and my previously mirrored drives are showing up as separate drives when i boot into my current windows installation. Am i trying to do the impossible here? Should i just buy a separate SATA/RAID PCI card and plug the SSD into that? Any help would be greatly appreciated.

• Can't get 1440x900 resolution with GRUB2 although vbeinfo says it's available

  - by TomSW

  I'm trying to use GRUB2 in graphical mode with 1440x900 resolution, but the result is always garbled nonsense: the highest resolution I can get is 1280x800. Word is from googling that long as vbeinfo lists a resolution, GRUB2 can use it. This doesn't seem to be true: vbeinfo says that 1440x900 is available but it doesn't work. Testing it from the GRUB2 command line: set gxfmode=1440x900 terminal_output gfxterm # -> garbled nonsense # back to trusty 640x480 terminal_output console The graphics card is an Intel GM965. Once linux boots the framebuffer switches to 1440x900. Added after epheminent's reply and various experiments vbeinfo lists two sets of modes. The first set runs from 0x160 to 0x16b, with resolutions 768x480, 960x600, 1280x800 and 1440x900 Then - after a bunch of text-only modes - the second set, containing resolutions 1024x768, 800x600, and 640x480 The first set of modes aren't altered by 915resolution. They all work except 1440x900. The resolution of modes in the second set can be altered using the 915resolution module / command available in GRUB2 = 1.99. # in /boot/grub/grub.cfg insmod 915resolution # 30, 32, 34 all work for me: all that varies is which modes are altered 915resolution 30 1440 900 # setting an impossible resolution changes the mode to "text-only" # in my case 1280x1024 is not supported 915resolution 30 1280 1024 Clearly, 1440x900 should just work: adding it with 915resolution is just a workaround.

• HP LaserJet 1515: Disable "refill" warning

  - by Pekka

  I have a HP LaserJet 1515 connected to a Windows 7 PC. The Magenta cartridge is empty; the printer shows a warning to that effect, and won't let me print even black-and-white documents any more. I can't turn the warning off manually using the printer's small console: When I try to enter any menu, the display says "Menu access disabled". I have no idea why. There is a setting to override the warning, but it can't be changed using the Network interface in the browser (Although it is there on the status page) According to the manual,the HP printing tool is supposed to offer a switch for this, but it won't install on my Windows 7. It just rumbles about for half an hour, to magnificently exit with an "unknown error" requiring a reboot. On second look, the problem seems to be that Windows 7 just isn't supported. There is no download link for the tool when you specify Windows 7 as your OS. I just want to print a black-and-white-document on a printer whose black cartridge is still 65% full. Is this indeed impossible? On second thought, I'm cross-posting this on the HP support forum. I'll update here if anything comes up.

• How can I recover my data from a damaged hard drive?

  - by krk

  a few days ago when I was working on windows my laptop was beaten on the side where the hard drive is located. As a result, it was damaged and I couldn't access the windows partition. I had to boot the linux one, which is working without any trouble. I have 2 partition formatted with ntfs, the one with windows on it, and the other one intended to store data. I mounted the windows partition from ubuntu and I could see all my files. But when I tried to mount the data partition it was impossible. It threw me an error, it couldn't recognize ntfs partition. I try to copy the damaged disk into an external hard drive using the command: dd if=/dev/sda of=/dev/sdb conv=noerror,sync The progress stopped at 60%. I was still unable to mount the data partition. Now I'm trying to backup my files using an utility called Photorec. The problem is that it is recovering my files in a disorderly way, it is all mixed up and I need my original directory structure, it will become an endless task to organize the files as they were before. Is there any way I can get my partition back?

• How can I use apt-get to resolve package dependencies when there are multiple versions in the repository?

  - by user1165144

  I've package a-package.deb which depends on b-package.deb in version 1.0. Everything works fine. But now a b-package in version 1.1 gets added to the repository. I'd suspect that apt-get installs the a-package and version 1.0 of the b-package. What really happens is, that a-package won't get installed: # apt-get install a-package Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: a-package : Depends: b-package (= 1.0) but 1.1 is to be installed E: Unable to correct problems, you have held broken packages. Is there a workaround to fix the behavior? Is there other software to use, that can handle the dependencies as defined?

• [SOLVED} How do I restore my audio after uninstalling Ventrilo?

  - by Marcx

  Hi, I've a Dell studio 1555 bought on september with Windows 7 64bit Professional on it. The audio device works proprerly, while listening to audio contents (from disk or internet) When I use Ventrilo, the audio from other people sounds good and I hear their voices clearly When I use any other VOIP programs like Teamspeak 3, MSN or Skype, I hear a disturbed voice, and it's impossible to comprehend something... Anyway everything worked fine until I installed Ventrilo, but removing it didn´t solve my problem. Update: Here's a sample of how I hear others people voices.. Audio Sample After some tests, also the desktop has the same problem. (I tried TeamSpeak3) Here are some details on my laptop and desktop Laptop Dell Studio 1555 Core 2 Duo P8600 2.4Ghz 4Gb Ram Dual Channel Ati HD 4570 512Mb dedicated (up to 2048) IDT High Definition Audio Desktop Motherboard Asus P5KPL-AM Dual Core CPU E5200 2.50Ghz 2x2GB PC6400 Dual Channel Ati Radeon HD 4650 512MB VIA High Definition Audio Both computers have Windows 7 Professional 64Bit. So how do I restore my audio? SOLVED The problem was in router firmware, there was a bug that recognized VoIP traffic as a DOS attack and the router grambled every packet... I've installed the newest firmware and everything is fine :)

• Routing connections through VPN based on hostname (not IP range)

  - by Michal M

  This bugs me immensly. I need to connect to client's network through VPN. But I definitely do not want to send all the traffic through client's network so this option is out of question. What I need basically is for the OS to know that all client's network subdomains (*.example.com) need to go through the VPN connection. I tried a couple of options: Changing order of services and setting the VPN on top, but this works the same as "Send all traffic over VPN connection". Using "VPN on Demand" option from network advanced options, but this feature is quite rubbish to be honest. Seems to work only in Safari (?!) and it doesn't route the connection, but it basically triggers the OS to connect to the selected VPN. The reason I need it to work based on hostnames rather than IP range is simple - my client has a lot of servers inside his network and it's impossible for me to remember all IPs. They are all within a range, but this doesn't help me remembering. Another option would be to put the VPN connection on the bottom of network services and untick "Send all traffic..." and then put all known hostnames in hosts file, but considering there could be hundreds of servers (therefore hostnames and ips too) it ridiculous job. And if new server appears on the network I'd need to edit the hosts file again. Sisyphean labours. However this works on Windows very simply. If a hostname is not available through default network interface, then it seems to try VPN connection and this works brilliantly. So, how can I achieve that on Mac, then? I know client's internal DNS addresses if that is of any help (like directing a certain domains through a different DNS)? PS. Using latest version 10.6.6. PS2. I am using VPN to access intranet, version control servers (svn://), samba shares and for SSH access to servers.

• Convert Public Folder to Shared Mailbox

  - by Lilienthal

  Due to a change in company policy, all existing Public Folders (PF) have to be phased out in favour of shared mailboxes. Unfortunately, they don't seem to have any procedures or guidelines for this migration and I can't find much online either. I've already migrated one of our public folders so far as a sort of test case. Because we still use Exchange 2003, we can't create real shared mailboxes as we would in 2007 or 2010 (With New-Mailbox -Shared ... in the Exchange Shell). Instead, I simply created a new account on the AD and assigned it a mailbox. I then set the PF's permissions to read-only to keep it in a consistent state and copied the entire folder to a local PST in Outlook 2010, from which the folder was in turn copied to the new mailbox. Permissions and Folder Visible were set for all users and the migration was successful. While this works, the whole procedure feels very hackish to me and not at all efficient. I'd welcome some input on automating or at least streamlining the process. Additionally, we are unsure of what to do with our mail-enabled Public Folders. Several of these are nested under other PFs, some of which are also mail-enabled. Preserving folder structure is a key requirement and this seems impossible at first glance. I've considered creating dummy accounts for all the email addresses from our mail-enabled PFs and then setting up automated rules to forward messages to a subfolder of the new shared mailboxes, but I am not familiar enough with Exchange to know if this is even possible. Further points of concern are the Calendars and Contact lists in our public folders. I suppose I'll be forced to create new mailboxes for every one of these we have as well, then set up share permissions for their Calendar and Contact items, but would be happy to be proven wrong.

• How to boost playback volume in real time on media recorded with a very low volume.

  - by L Marksman

  I have never heard a satisfactory answer to this often misunderstood question, let me explain. Lets say I have a sound card and earphones/speakers that can play back audio loud enough in most cases. This is great but the problem is that you always find people who do not know how to record audio, from Youtube video's to music. So now you end up with a audio playback that only uses 10% or less of the capacity of your sound hardware, in vista/win 7 you will see this frequently in the mixer with the volume pushed up to max but the green sound level only goes up a millimeter or two. I am looking for (preferably free) software or a method to boost the sound level of any audio from any source in real time to use more of my hardware capacity similar to what VLC media player can do. Oh and please, do not tell me it is impossible. I am not trying to boost the volume past what my hardware is capable of, I am just trying to use my hardware's full capacity. Also please do not tell met to buy new hardware, I know I can use hardware amplification, I don't want to (like many others) spend money on a simple little problem like this. Thanks!

• MicroSD card getting corrupted for no good reason

  - by ChaosR

  I recently bought an MicroSD card online. It's a Sandisk 16GB class 2. However, it has a nasty problem. Every time I fill it with my data, the fat tables get corrupted. I've tried reformatting it, blanking it, doesn't seem to solve the problem. I have tried windows and linux (ubuntu), both have the problem. I've used my usb microsd readers, and even tried putting it in my phone and putting data on it from there. All have this problem. Now the really odd thing is, besides the corrupted file tables, no programs can find anything wrong with the hardware. I've tried both chkdisk and "badblocks -w", neither give any type of error. Now I don't know if the actual data gets corrupted, or if its just filesystem tables. What happens is that one or more folders start showing a load of chinese-charred (random UTF8 symbols I suppose) folders and files, and it is impossible to do anything with those. All the other data (outside of the corrupted folders) seems fine. I've tried to test it, and the problem doesn't seem to show up until I fill the disk upto about 3~4GB. After that I can still access the data. But as soon as I eject/safely remove/unmount it, the bad things happen somehow. Next time I plug it in, the folders I most recently wrote to (but sometimes also the folders I wrote the time before last time to) are all gibberish. Does anybody have any clue what might be going on here?

• Can I use squid (or anything) to do this?

  - by user269334

  I have a really crappy VPS, and a really good computer at my office (with a really good internet connection), but behind a NAT. Is it possible to expose my good computer by doing this: 1. The good computer connects to the VPS (and keeps the connection alive) 2. The users connects to the VPS, and sends http(s) requests to the VPS. 3. The VPS just passes that http(s) requests to the good computer (including some identifications, so the servers can distinguish connections) 4. The good computer passes that http(s) response to the VPS 5. In turn, the VPS receives the http(s) response, and passes back to the client. Is it possible to do this? (btw, the VPS and the good computer are located in different countries) And also, is this "reverse proxy"? I heard that reverse proxy is for protecting the internal network by putting a middle server. And will this affect SSL configurations? (or make SSL impossible?) I'm intending to run nginx on the good computer. Thanks in advance : )

• Is there a way to measure wifi traffic on a network from a client?

  - by millimoose

  Is there some way (preferrably one that comes with an existing tool) to measure the traffic going through the whole WiFi network from a computer connected to it? (That is, not from the AP or something between the modem and AP.) My situation is this: a few months back, the internet connection at my parent's place got really sluggish and laggy. (Lag spikes that cause page loads to time out etc, connections plain getting lost and dropping packets forever.) It's impossible to get mom's husband to do anything about this because he brushes this off with something like "just tell your sister to turn off torrents". Unfortunately the WiFi router's firmware doesn't do traffic logging. I'm not going to risk bricking it to put WRT on it; nor am I keen on rewiring the network to add a proxy to analyse the traffic. (I'm one of those people that make computers break just by looking at them, except machines I own.) I'd like to be able to find out roughly how much data is going over the air here while all the LAN wires are out of the router, all the computers accused of torrenting are off, etc. The idea is to either show that: Even if everything but my macbook is turned off, something is congesting the network. The husband is a systems developer and has a whole lot of mysterious hardware that's not to be touched around, one of them might be culprit. There is barely any traffic on the network, but the internet is still sluggish. Meaning this is likely a problem the ISP should solve. (Some hardware of theirs being glitchy, someone on an aggregated line hogging it constantly...) The network is encrypted, but I can temporarily set it to open for the sake of finding this out. So, in conclusion? Can this be done? Or is there some alternative way I could try to diagnose the problem?
