• How can I send super large files directly to another computer in the Internet for free?

  - by Cruise

  I regulary need to transfer very large files (30 GB) to my friend - financial statistics. I don't have any problem with bandwidth: it is very broad here. I did some research in the area, so: 1. I would not use FTP, as it is very tricky to get it working behind a NAT. 2. I would not use Skype/MSN/ICQ, as it is not designed for file transfer and it underperforms on the huge files. 3. I would not use file-sharing services, as I need to pay for big files (30 GB is a problem here) and I don't like holding any piece of my data on the third-party server. So, I need some smart tool that will do what I need: sending files directly browser-to-browser and not browser-server-browser. Is it so complex? Is there some web application in the Internet that can do this?

• Which linux x86 hardware keystore?

  - by byeo

  I'm terminating SSL/TLS in my DMZ and I have to assume that machine will be hacked. At which point my certificates are compromised. Previously I've used nCipher hardware keystore/accelerator to solve this issue. These cards won't reveal the private key even to root. The card performs the encryption and decryption onboard and is hardened against physical attack. The only way to get at the keys is by attaching a smart card reader to the card itself. I'm having trouble finding information about something to recreate this approach. Is this the domain of specialist switches and firewalls these days? This old page references some of the old hardware: http://www.kegel.com/ssl/hw.html#cards

• How to prevent these executables from starting up?

  - by TomWij

  After removing the following executables from starting up, in the near future they reappear again: DDMService.exe: Re-enabled when visiting a DivX video online. DivXUpdate.exe: Re-enabled when visiting a DivX video online. GoogleUpdate.exe: Re-enabled task, I think by Google Chrome? I see no auto-update option. iPodService.exe: Re-enables after starting iTunes. iTunesHelper.exe: Re-enables after starting iTunes, useless on SSDs. Reader_sl.exe: Re-enables when updating Adobe Reader, useless on SSDs. It bores me that these processes keep popping back up, while my software functions well without them. I'm smart enough to update the software weekly through FileHippo so I don't need automatic updates. What can I do to never see these processes again? Even after reinstallation of those applications... A general solution is also welcome! :-)

• HDD not detected whenever first power on (detected at BIOS level)

  - by Alvin Lim

  I am using Asus P8H61-M LX Motherboard with latest version of BIOS: 4401 One SATA-3 Western Digital Black Series 1.5TB is attached to SATA port 0 A Samsung 22x DVDRW SATA drive attached to SATA Port 1. ps/2 Logitech mouse and keyboard. CPU is i3 with DDR3 8Gb RAM. no other devices are installed. My problem is that when I turn on the computer, the WD HDD is not detected. ie cannot be booted. I have to press ctrl+alt+del in order to get it detected. I'd used the WD data lifeguard software to scan the HDD, the smart status is OK, the surface scan does not show any error at all. Where did I do wrong? Any advice is greatly appreciated.

• Computer making strange sound when turned on, ever since power outage

  - by Dot NET

  Recently we experienced a power outage, and the PC was off. However, once the power came back, I switched on the PC and heard a strange noise - almost as if the hard disk or fans were struggling to work. I can't really describe the sound, but it's a laboured, loud sound almost like a jack-hammer. This has been persisting ever since the power outage, however the noise stops after around 10 minutes or so, and doesn't start again until the computer is turned off and on again. At first I thought it had something to do with the HDD, but all my files are intact, chkdsk did not report any issues and performance is 100% unchanged, even in games (so the gfx card is fine, and so is the HDD most likely). My PC setup basically has around 3 cooling fans, but I'm not sure if it's one of these either as the noise actually stops after 10 minutes or so, and if I leave the PC on for 4 hours (for example) the noise never starts again. It's there solely when turning on the PC. I haven't got a UPS, and it's important to note that the computer was not on when the power went out - it was merely plugged in. I then promptly unplugged the PC once the power was out, and only plugged it in again when the power came back. Could it be the power supply? Unfortunately I can't open my tower as I would void the warranty. Are there any tests which I could carry out without voiding the warranty?

• Computer temporarily freezes and then resumes

  - by trizicus

  This happens on ALL operating systems (7, Ubuntu, etc.). What happens is everything for 1-3 seconds becomes unresponsive, I then hear what sounds like my other internal hard drive 'spinning up', and then viola everything is responsive again. Note: Already ran SMART tests, no issues at all. I think issue is that the HDD spins down and when need it gets 'turned-on' (OS settings turn off HDD's after 20 mins of inactivity) and because my pagefile is on the other HDD it causes OS to temporarily freeze. Need more tips, and insight. Thanks More info: Running Quad CPU, 4GB RAM, Intel SSD, GT 240.

• My NTFS Partition keeps becoming "unusable" on Ubuntu, Any Ideas?

  - by gopherman

  I just purchased a new 2TB Drive External Seagate, My main system uses both Windows and Ubuntu So I am pretty much stuck with keeping my drive as NTFS. I have done this without any problems before but since I got this new drive I have been having issues. When I first load up Ubuntu the drive mounts and runs fine, after an unspecified amount of time i start getting Input/Output errors when accessing the drive. When I goto the Disk Utility I get a message stating the drive is "Unknown or Unused", If I disconnect and reconnect the drive or reboot everything is fine again. There's no errors coming up with S.M.A.R.T and it seems to work fine while under windows. Any thoughts?

• Why does the Internet WI-FI connection of my laptop disconnect when I connect the ethernet cable to the LAN?

  - by Joey Hammer

  Why does the Internet WI-FI connection of my laptop disconnect when I connect the ethernet cable to the LAN? These are two separate networks, the LAN is without Internet, I just use it to connect the tablet to the laptop and smart phone in my home network. The WI-FI is owned by the landlady and connects to the Internet. I know it should be possible to be connected both to the Internet through WI-FI and to my other computers and gadgets through the LAN because sometimes it works, but sometimes when I connect the ethernet cable the WI-FI disconnects and I wonder why? Pongy OS: Windows 7

• Tests for hard drive health

  - by Samik R

  I have a 5-year old hard drive (bought new at the time), but it was sitting in my closet for 5 years, unused. I have just started using it, and seems to be getting a whirring sound (rather distinct from the other noises like fans etc.). I ran a few diagnostics tests, like Seagate's SeaTools, and the SMART test, and a few generic tests and all passed. Should I be concerned? Is there any other test that I should run? It's an internal IDE WD 5400RPM drive. Being used for a desktop, which is itself pretty high-end (AMD Phenom II X6 1100T, AMD Radeon GPU etc.), but would be used rather occasionally to begin with (avg. 1-2 hrs. per day). Thanks for any pointers.

• How to partition a 1 TB drive for performance on a windows development machine?

  - by dip

  I saw a similar question for linux, but nothing for windows. I'm getting a new 1TB drive for my dev box @ work. The OS will be Windows 7 Pro with 8GB of RAM and just the single 1TB drive. Backups are not a concern, and I won't be storing large multimedia files. I want the fastest possible performance for general windows usage and for compilation. I will defrag nightly with a smart defragger liker perfectdisk. Should I just go with a single partition, or is there some way I can lay things out for the best performance?

• Laptop crashes when connecting to external harddisk

  - by Gnot

  I recently had a problem with my laptop. when I booted up the machine, I would get a SMART failure error message and when I pressed F1 to continue, it would take a very long time to boot and it would come back to the same error message again. Thinking that my hard disk was dying, I bought a new hard disk and installed on my laptop and so now my laptop is alright. However I need to recover data from that old hard disk, so I bought an external hard disk case and placed the old hard disk onto the case and connected to my laptop with USB. The first few times when I connected, I could see the files from the old hard disk and managed to copy some files over although it took extremely long to transfer. But now whenever I connect to the old hard disk, after a few minutes, my laptop will crash and re-boot. Do you think my old hard disk is dead beyond repair? Or you can offer some help here? Any assistance would be appreciated!

• Looking for advice on using dd to backup a dual boot laptop.

  - by AvatarOfChronos

  My questions boils down to this. If I do "dd if=/dev/sda of=usbdrive" can anybody confirm that this will get everything including mbr/partition information/all four partitions and create a drive that I can swap with the failing internal drive without losing anything? If this is done while the computer is running will it still copy everything? At this point I'm afraid to shutdown the computer for fear of it never starting again. Secondly, how tolerant is dd of failing drives? Has anybody used it to recover a half dead drive before that can share any potential pitfalls? Did it get the data ok or is this going to be a hope for the best kind of situation? And lastly, If the usbdrive is larger than the failing internal drive I'll still be able to expand the partitions later so I'm not losing space? this last part seems silly to ask but with my current streak of bad luck I'll end up overwriting some magic bit and forever turning a 640gb hdd into a 500gb hdd. Also if anybody has a better solution to create a complete clone that gets everything I'm all for hearing about it. PostScript: I had been making periodic backups however when whatever miasma that killed the laptop struck it also got the NAS :( Post PostScript: both devices were on a UPS system.

• disk write cache buffer and separate power supply

  - by HugoRune

  Windows has a setting to turn off the write-cache buffer (see image) Turn off Windows write-cache buffer flushing on the device To prevent data loss, do not select this check box unless the device has a separate power supply that allows the device to flush its buffer in case of power failure. Is it feasible and economical to get such a "separate power supply" for the internal sata drives of a non-server PC? Under what name is such a power supply sold? I know that there are UPS devices that can be connected to external drives,but what is required to be able to switch this setting safely on for an internal disk? The setting has different descriptions in different version of windows Windows XP: Enable write caching on the disk This setting enables write caching in Windows to improve disk performance, but a power outage or equipment failure might result in data loss or corruption. Windows Server 2003: Enable write caching on the disk Recommended only for disks with a backup power supply. This setting further improves disk performance, but it also increases the risk of data loss if the disk loses power. Windows Vista: Enable advanced performance Recommended only for disks with a backup power supply. This setting further improves disk performance, but it also increases the risk of data loss if the disk loses power. Windows 7 and 8: Turn off Windows write-cache buffer flushing on the device To prevent data loss, do not select this check box unless the device has a separate power supply that allows the device to flush its buffer in case of power failure. This article by Raymond Chen has some more detailed information about what the setting does.

• How to copy text out of a PDF without losing formatting?

  - by Colen

  When I copy text out of a PDF file and into a text editor, it ends up mangled in a variety of ways. Formatting like bold and italics are lost; soft line breaks within a paragraph of text are converted to hard line breaks; dashes to break a word over two lines are preserved even when they shouldn't be; and single and double quotes are replaced with ? signs. Ideally, I'd like to be able to copy text from a PDF and have formatting converted to HTML codes, "smart quotes" converted to " and ', and line breaks done properly. Is there any way to do this?

• Alien: .rpm -> .deb | Compability / Built per system?

  - by MaddinXx

  At the moment I'm playing a bit with alien (for OpenVZ packages on Debian) and was wondering myself about one question for which I was not able to find an answer anywhere. Therefor I thought it might be smart to ask here :) The question is... If I convert a .rpm to .deb on a system, how compatible is this .deb package? What do I mean? Will the .deb be working on other systems as well or is it per-system, e.g. that on every system the .deb package will be little different? That i386 and x86_64 are different is clear, so this doesn't need to be answered :) Examples that would be nice to know are for example: .deb built on Debian 6 64-bit - Ubuntu 12.04 64-bit (compatible?) .deb built on Debian 6 64-bit - Debian 5 64-bit (compatible?) etc. Thanks anyone reading this / helping me! Regards, Michel

• Steps to install solely ubuntu 13.04 on Dell inspiron 14z ultrabook with SSD+HDD

  - by rishy

  I have tried a few things like disabling the Intel smart response, choosing AHCI in BIOS. But there are certain problems I am still facing. I can't see my SSD during the installation of ubuntu (I am planning to install Ubuntu on my SSD and other files on HDD). When I run Ubuntu my laptop gets overheated and battery backup reduces to 90 minutes. (I guess it's related to my graphic driver ATI Raedon HD 7570). Cooling fan seems to run at its fullest, it was working much better in windows. So, overall I wanted to know what are the exact steps I need to follow to install Ubuntu on my SSD and then use my HDD to keep other files, How can I get rid of overheating and battery backup problem?

• What are the typical methods used to scale up/out email storage servers?

  - by nareshov

  Hi, What I've tried: I have two email storage architectures. Old and new. Old: courier-imapds on several (18+) 1TB-storage servers. If one of them show signs of running out of disk space, we migrate a few email accounts to another server. the servers don't have replicas. no backups either. New: dovecot2 on a single huge server with 16TB (SATA) storage and a few SSDs we store fresh mails on the SSDs and run a doveadm purge to move mails older than a day to the SATA disks there is an identical server which has a max-15min-old rsync backup from the primary server higher-ups/management wanted to pack in as much storage as possible per server in order to minimise the cost of SSDs per server the rsync'ing is done because GlusterFS wasn't replicating well under that high small/random-IO. scaling out was expected to be done with provisioning another pair of such huge servers on facing disk-crunch issues like in the old architecture, manual moving of email accounts would be done. Concerns/doubts: I'm not convinced with the synchronously-replicated filesystem idea works well for heavy random/small-IO. GlusterFS isn't working for us yet, I'm not sure if there's another filesystem out there for this use case. The idea was to keep identical pairs and use DNS round-robin for email delivery and IMAP/POP3 access. And if one the servers went down for whatever reasons (planned/unplanned), we'd move the IP to the other server in the pair. In filesystems like Lustre, I get the advantage of a single namespace whereby I do not have to worry about manually migrating accounts around and updating MAILHOME paths and other metadata/data. Questions: What are the typical methods used to scale up/out with the traditional software (courier-imapd / dovecot)? Do traditional software that store on a locally mounted filesystem pose a roadblock to scale out with minimal "problems"? Does one have to re-write (parts of) these to work with an object-storage of some sort - such as OpenStack object storage?

• monitor a folder and send files via ftp to clients

  - by user73109

  I am looking for software that will monitor a specific folder and when a file is created in it send that file off via ftp to a client associated with that folder by the software. I have tried software such as smart FTP and cute FTP and they don't seem to monitor folders very consistently. Some of the options with them were to write scripts to delete duplicated files from the transfer queue. I really don't want to have to write scripts for software I purchase. I am not opposed to needing scripting or writing it but I feel I shouldn't have to write scripting to make there software properly do some thing it says it does out of the box. I am currently trying to do this on a Windows XP box though running on a Server 2003 is an option if it would make things easier. I really just want pointed in the correct direction this is all fairly foreign to me

• HP DL380 G5 Predictive failure of a new drive

  - by CharlieJ

  Consolidated Error Report: Controller: Smart Array P400 in slot 3 Device: Physical Drive 1I:1:1 Message: Predictive failure. We have an HP DL380 G5 server with two 72GB 15k SAS drives configured in RAID1. A couple weeks ago, the server reported a drive failure on Drive 1. We replaced the drive with a brand new HDD -- same spares number. A few days ago, the server started reporting a predictive drive failure on the new drive, in the same bay. Is it likely the new drive is bad... or more likely we have a bay failure problem? This is a production server, so any advice would be appreciated. I have another spare drive, so I can hot swap it if this is a fluke and new drive is just bad. THANKS! CharlieJ

• Cisco VoIP stuck as Unregistered?

  - by Shifty

  Question: Why is one VoIP stuck as Unregistered? Background: We have a Cisco UC540 Small Business switch/router/voip combo. This phone was working until I powered everything down to install a larger UPS unit. The phone originally had a status of "Deceased". I removed the registration and tried to add it again. Now it just sits as "Unregistered". I even tried giving it another extension. I am stuck using the Cisco Communication Assistant since this is small business hardware. There is very limited CLI access. Also, from what I heard, if you access the CLI with out cisco permission, you will void any warranty. The phone in question is a Cisco SPA501G. It is connected to a SG300-28P. There are 5 other phones on this switch working just fine. I have tried other ports with no luck. Both the link and PoE lights are lit up. Any ideas?

• How do I disable tablet gestures in windows 8?

  - by ???

  I'm using a Wacom Intuos4 and I have recently upgraded to Windows 8. I don't have a problem when using Photoshop however I occasionally draw on flash based online boards. The problem is, when I drag the pen in a direction repetitively (which is basically all I do when drawing) it's detected as a gesture, sometimes causing Chrome to go to the previous page (left drag) and making me lose the entire thing. Is there a way to disable these "gestures"? I believe this is not something caused by Windows 8 (or Charms) because I run Windows in English although it's not the initial language that Windows was installed in. I changed to English long after the installation. When Windows takes a move as a gesture, a small text pops up next to the cursor informing me about what I have just done and those pop ups are not even in English. I'm sorry for failing to be any more specific here but these gestures could be a feature of either Windows (unlikely), the tablet, Chrome or the computer itself. It's an Acer Aspire and it has one of those little stickers on it that specifies some of the features and one of them reads "Multi-Gesture" (referring to the touchpad, I guess). Could it be that this Multi-Gesture feature somehow decided to expand and apply for my tablet as well? If so, how do I disable it?

• PC doesn't POST with a certain model of PSU

  - by Core Xii

  I have this PC with an Asus P5N32-E SLI motherboard and an Intel Q6600 CPU. I got a new RX-5300 PSU, but it didn't work. The motherboard power LED is on fine When I switch power on, the PC powers up briefly (0.5-1 sec) then shuts down From there on out when I switch power on, it stays on, all fans and components seem to be receiving power, but the motherboard won't POST. No video output, no PC speaker beeps, nothing If I turn the hard switch on the PSU off and then back on again, go to step 2; The PC turns on and then off immediately again, and on subsequent power-ups it stays on but won't POST I disconnected every component but the motherboard, CPU and PSU. Still nothing. I tried three other models of PSU on this PC, both of higher (600) and lower (<300) wattage than the 530 on the RX-5300 and they all work fine. At this point I was convinced the PSU was faulty so I returned it. When the replacement arrived, it behaved exactly the same. So two different units of RX-5300 both with the same symptoms, neither working with this motherboard + CPU. Yet, three other models of PSU work perfectly fine. The PC store couldn't reproduce my problem with the returned PSU. I tried resetting the CMOS with the jumper. I tried with both the 4 and 4+4 (with and without the extra +4 connected) CPU connectors (curiously the RX-5300 comes equipped with both). Could it be a statistical probability that I get two units of the same model of PSU that are faulty in the exact same manner? Could the RX-5300 model itself be somehow incompatible with this motherboard? I was under the impression that PSUs were pretty much universal so long as you have the wattage. Could the motherboard be broken in some such a way as to work with certain PSUs but not others? What's going on here?
