  • USB sticks optimized for OS booting and virus removal [closed]

    - by Rupert
    I'm looking to buy some usb sticks which will mainly be used in tech support for the purposes of removing viruses and booting up various OS's. Therefore, I am looking for the following features: Write protected switch (so that they may be safely plugged in to potentially infected machines) As fast as possible (so that loading, for example, a windows recovery, doesn't take forever) At least 4GB in size Any other features that might be useful for the above purpose Price is no object but, of course, the cheaper the better.

  • Does 64bit Windows 8 have the same 75% memory-usage limitation for applications as Windows 7?

    - by Barleyman
    64bit Windows 7 (and Windows Vista) have a built-in limit of not being able to use the last 25% of RAM. You will get a low memory warning when you get close to the limit. Even if you disable that warning, applications will run out of memory and crash since the OS will refuse to allocate memory from that last 25%. That was fine when Vista was designed, when machines had 1 GB of total memory, but is pretty daft for today's 8 GB machines. Yes, the system will run cache, etc. on that extra 2 GB, but running out of memory when you have "merely" 2 GB left.... NB: this has nothing to do with the page file. If you limit the page file to a sensible size like 2 GB, you will still see this behavior. The system will cram the page file to the last byte while refusing to touch that 1/4th of the RAM. Does Windows 8 change this behavior? Is there now some fixed minimum free RAM requirement, like 512 MB, or is it still 25%? Can you actually adjust the low memory limit? EDIT: Here is another older post here which discusses this same behavior on Windows 7. There is fixed 25% limit in Windows 7 and I'd like to know if it's still in Windows 8. Windows 7 / Page File Disabled / 12 GB RAM / 2+ GB RAM free and "your computer is running low on memory" Edit2: Here is another link discussing the low memory warning and how to disable it. Note he claims the limit for RAM usage is 80%, not 75%. It would seem to be correct as you can in fact allocate 6.4GB of RAM with 8GB machine. Anything above and beyond that goes to the pagefile, though. http://halflight.com.au/2011/04/06/how-to-disable-low-memory-warnings-and-the-advantages-of-removing-the-page-file/ Edit3: a Here's couple of process explorer screenshots that demonstrate how it goes down. Exhibit1: https://dl.dropbox.com/u/42068601/sysinfo.jpg Exhibit2: https://dl.dropbox.com/u/42068601/sysint2.jpg You can see that Windows 7 will use the memory 6.4GB as the very last resort. I have low memory warning switched off here so programs crashed at the last screenshot allocation. With low memory warning turned on, it starts nagging before you can push OS to use that remaining 1.6GB. The question is not "Is it OK windows does not want to allocate last 20% of RAM because X", it's "Does Windows 8 still behave this way". With 16GB this really becomes dumb.

  • Where do Client-only rules execute on a single profile with multiple Outlooks open?

    - by Roger
    I have two outlooks 2007 open on two different machines logged in to the same account. The issue is I have is with client-only rules for sound alerts executing intermittently. All other rules work correctly, because they are run on the Exchange Server, but the client-only ones seem to pick and choose when to produce sounds. Is there something I can do to make my client-only rules run reliably on one particular instance of outlook?

  • IIS 7 Web service access

    - by Aharon Manne
    I am trying to debug a simple web service. I have IIS 7 installed on my development machine (Windows 7), and have installed the web service. I can access it from my development machine, but not from any other machine in the local network.I opened the firewall to HTTP access, and I can access the default website from other machines, so it is not the firewall.What security settings should I look at to try to allow devices on the LAN to access the web service?

  • Alternative to Dropbox (on my server)?

    - by jweede
    I love using Dropbox to sync files between all my machines, and I've heard it uses rsync internally to keep files synced. Sometimes I need to sync very large things, and I don't necessarily want to pay for storage space on someone else's server when I have my own. So does anyone know of any nice cross-platform (pref. open source) automatic file-sync applications out there for this?

    - by will
    I'm using Live Mesh to sync files. I have two machines, one has my work and the second was offline. When I booted the second Live Mesh deleted all the content of a folder from my live desktop. I can see the entry in the news section of my live desktop (delete 74 folders...). Anyone know if there's a way to undeleted or recover these files? Thanks!

  • Anti-virus protection question?

    - by DaBaer
    About 4 years ago, I found Kaspersky and have been using the most current version since. Most people try and argue the use of AVG or Avast to me, and there are some very solid reasons I do not go that route. Over the years, I have found Kasp to become bulkier and bulkier, and have had issues setting it up for friends/family/clients. I am just curios on possible recommendations from other users, with my criteria in mind: What I like about Kasp in the past: The license sold in stores in a 3 pack, is considered a commercial license, and emails from Kasp in response to my questions, make it clear that I can do with the 3 licenses that I want, providing I do not use more than 3 installs per Key. So, allowed me to buy 3, 5, and 7 packs, and resell to users at a cheaper cost than what they would pay if they bought their own license. The ability to easily obtain a currently updated .exe for installation on multiple peoples machines. Power of the scan. Kasp has been a good solution for me (even when using a trial license) on cleaning up machines that were badly infected (in which AVG and AVAST were unable to.) Speed of install/update. After a cleanup of malwarebytes, spybot, mcafee stinger, ccleaner, and combofix, I used to be able to get Kasp Int Security installed and updated in around 5 minutes. The issues that I have with the free AV, is strength of protection. In my opinion for someone who is a 'power use' these are good alternatives, because such a user should be trained or knowledgeable enough to be careful and not get themselves in trouble. Most of the users I assist, are too PC ignorant to know any better, and go hogwild on the web. It has been my experience that the number of people coming back to me with spyware/malware/virus issues since I have converted from AVG to Kasp has been cut down to around 20% of what it used to be 4 or 5 years ago. In a perfect world, I could install and use Kasp Internet Security 2008, and be very happy. But this is not the case anymore. So after this long description of what I used, and have used, does anyone have any good recommendations on AV that isn't going to cost me too much per install?

  • After Windows 8 installation I can't access BIOS settings anymore

    - by Diogo
    Today I installed Windows 8 Consumer Preview on one of my notebook machines and I noticed that I can't access BIOS settings if I use the "Shut down" Windows option on Settings/Power menu. If I use the "Restart" option, my BIOS allow me to enter on it's settings over "F2" again. Is this happening to someone else? I looked over Windows 8 oficial forum and couldn't find such event. Is this something foreseeable to the new Windows 8?

  • Complete machine freezes...at a loss

    - by user28818
    Guys, We built around 12 machines a few months ago to run Ubuntu. They each have the following specs: ASUS Z8NA-D6 motherboard Dual quad core Intel(R) Xeon(R) CPU E5520 @ 2.27GHz OCZ Mod Extreme Pro 500W power supply 12 GB Kingston RAM Nvidia GeForce 9800 GT graphics card My machine ran well for awhile. However, it started experiencing random lockups. These lockups are not X lockups, they are complete system freezes. The nic stops responding, the magic sysrq buttons won't work. The machine is dead. I first suspected RAM. Memtest86 didn't find anything, but I replaced the RAM anyway. Still, lockups. So I replaced the graphics card. Still, more lockups. They became more and more frequent and started to happen 2-3 times a day. So I replaced the motherboard and power supply in one fell swoop. Suddenly, no more lockups! Woohoo! Except, a week later, in the morning, the machine wouldn't wake up. I reset it, started it up, and the log files showed the last entry at around 11 pm the evening before. This has started occurring with more frequency...now just about every morning I come in, the machine is locked up, and has been since the night before. Yesterday, in the 3 weeks since I replaced the motherboard and power supply, the machine actually locked up on in in mid-work. This is the first time since replacing the two (MB and PS) that this happened while I was using it. All others occurred while I was away. I'm at a loss. Nothing is in syslog or message that would indicate a problem around the time of the lockup. Temps are good...I use lmsensors to monitor and have a script that writes the output to file every minute. They never get that high. The only thing I haven't replaced at this point is the case and the harddrives. I doubt either could be the cause. What would you do if you were in my shoes? Is there a troubleshooting approach I'm missing? For the record, all of the other machines, all eleven of them, don't have any problems. They're all running the same version of Ubuntu (Lucid) that I am. Thanks!

  • Ubuntu hardware compatability

    - by CT
    I have only previously played with ubuntu using virtual machines with VMware Fusion. So everything just sort of worked. I've never had to install any drivers. I'm considering putting it on some real hardware and using it as a media center. What should I be looking for as far as checking hardware compatibility? How does installing drivers work? Any quick and easy recommendations / guides?

  • Find XP client DNS settings in the registry?

    - by jimmymcnulty
    I'm troubleshooting an issue and I need to find where client XP machines store their DNS information. I have a server with 3 NICs. 1 one of them has DNS information and two of them are in a private network not using DNS. It appears to be NameServer entry under System\CurrentControlSet\Services\TCPip\parameters\Interfaces\guid. Anywhere else that info would be found?

  • Dlink search is hijacking my browser

    - by James
    For months now "DLink search" has been hijacking my search engines. I use google chrome, and I have organized my search engines in the handy dandy "manage search engines" tool about a TRILLION times. It never even says D-link is hacking my search engines. It does not show up! I have read many posts on this forum and others saying that to fix this problem from internet explorer: Setup, internet options, yadayada, magical fairies, and you are solved, but my browser is google chrome! How am I supposed to do this from there! I do not know how to re-setup my Dlink router, which is the cause of the problem! HOW? In those posts with the magical fairies fixing it, HUNDREDS responded saying, "yep, those fairies definitely fixed it right. :)" These people were so satisfied. IT WORKED FOR THEM, WHY NOT ME. I look at it and go ":(" because it does not help me. There are no options for anything to do with this in GOOGLE chrome. PLEASE EXPLAIN and HELP. I see no "SETUP" option, no "Internet Options" button, no anything. BTW the exact posts are these: "Uncheck Advanced DNS in the router internet setup. This will take care of it. I had this problem with my DLink router before." "I had this issue with my DIR-655 and unchecking the Advanced DNS setting in Setup - Internet - Manual Internet Connection Setup fixed it." "If this is just internet explorer, you can go to Tools Internet Options or Internet Options in Control Panel. From here, go to the advanced tab and click the Reset button." "I would set the router's DNS to a site like OpenDNS, and I would ensure the machines are set to get their DNS settings via DHCP or set the machine's DNS setting to OpenDNS. If the router's DNS looks like it was messed with, some bad software know the default passwords for routers and could have changed it. If you don't already I would make sure the password to the router is not default or easy to guess. I've had spyware change a machine's DNS, but the fact it is happening on all machines makes me wonder if it is the router." "Something got into your router and changed the dns server most likely, do a hard reset of the router and then change the password to something strong. Also check for a firmware update for the router and apply it as soon as possible."

  • Testifying rasing net.core.somaxconn can make a difference

    - by petermolnar
    I got into an argument on the net.core.somaxconn parameter: I was told that it will not make any difference if we change the default 128. I believed this might be enough proof: "If the backlog argument is greater than the value in /proc/sys/net/core/somaxconn, then it is silently truncated to that value" http://linux.die.net/man/2/listen but it's not. Does anyone know a method to testify this with two machines, sitting on a Gbit network? The best would be against MySQL, LVS, apache2 ( 2.2 ), memcached.

    I'm using a Linux machine at work, and started using at home in a VM for some home development. I have a vimrc and a bashrc with some configuration, that are useful for both machines. What is the best way to sync them? Create a symlink for each file in my home folder pointing out to a the respectives files in my Dropbox sync folder? Is this possible (delete .bashrc and create a symlink instead)?

  • How can I determine the sector size on an external hard drive?

    - by sigint
    Hard drives are transitioning from 512 byte to 4096 byte sector sizes, and it looks like Windows XP won't support these newer drives without additional software (such as WDalign from Western Digital) My question is: how does this affect external hard drives? I'll be buying a 1TB USB external drive, and it'll be plugged into a mix of Windows 7 and XP machines. Is there an easy way to tell what the sector size on an external hard drive is?

  • Maximise network transfer speed of various applications

    - by Alex
    When using nc, scp, wget to transfer files between 2 machines on a dedicated 2Mbps link, I get speeds between 0.5 and 1 Mbps. However, when I use iperf -c 10.0.1.4 -t 20 -P 12 (for example) I can maximise the speed of the link (getting stable 2Mbps). Is there a way to make single stream transfers (such as those done by scp) to utilise all/most of the link? Some kind of tcp settings, or iptables...?
