• Networking problems in VMWare with wireless bridge

  - by Robert Koritnik

  Barebone data: virtualization: VMWare Workstation 6.5 (latest) Host: Windows Server 2008 x64 Guest: Windows Server 2008 x86 Host network adapter: Ethernet (see comment) Host network adapter: Wireless (see comment) Guest ethernet network adapter 1: Bridged VMNet (automatic) Guest ethernet network adapter 2: Host only VMNet comment: my host has LAN and Wifi but only one at the same time. I'm either wired or wireless. Never both. So bridged connection on VM goes either via wire or air. Problem When I'm wirelessly connected on the host and I access internet within VM my connection just gets stalled (not dropped). It doesn't experience any timeout whatsoever, it just stops downloading/communicating. For instance: I start downloading a file with a browser (IE/FF/CR doesn't matter) and I have to pause/restart download when speed drops to 0. I could wait indefinitely but connection won't pick-up automatically. What did I miss in my network configuration? Update 1 I've tested this in various combinations. This works fine when host is connected via Ethernet. But when host is connected via Wifi, the connection on the guest works as previously described. It connects fine. It gets a valid IP from DHCP... Everything is cool as long as you don't start doing some intensive network traffic (ie. download a 2MB file) In this case it starts downloading and stops after a while. Speed just drops to 0B/s... Sometimes it picks up back, sometimes it doesn't. Connection still stays and works. I can ping around with no problem.

• How can I avoid an error in this .htaccess file?

  - by mipadi

  I have a blog. The blog is stored under the /blog/ prefix on my website. It has the usual URLs for a blog, so articles have URLs in the format /blog/:year/:month/:day/:title/. First and foremost, I want to automatically redirect visitors to the www subdomain (in case they leave that off), and internally rewrite the root URL to /blog/, so that the front page of the blog appears on the front page of the site. I have accomplished that with the following set of rewrite rules in my .htaccess file: RewriteEngine On # Rewrite monkey-robot.com to www.monkey-robot.com RewriteCond %{HTTP_HOST} ^monkey-robot\.com$ RewriteRule ^(.*)$ http://www.monkey-robot.com/$1 [R=301,L] RewriteRule ^$ /blog/ [L] RewriteRule ^feeds/blog/?$ /feeds/blog/atom.xml [L] That works fine. The problem is that the front page of the blog now appears at two distinct URLs: / and /blog/. So I'd like to redirect the /blog/ URL to the root URL. Initially I tried to accomplish this with the following set of rewrite rules: RewriteEngine On # Rewrite monkey-robot.com to www.monkey-robot.com RewriteCond %{HTTP_HOST} ^monkey-robot\.com$ RewriteRule ^(.*)$ http://www.monkey-robot.com/$1 [R=301,L] RewriteRule ^$ /blog/ [L] RewriteRule ^blog/?$ / [R,L] RewriteRule ^feeds/blog/?$ /feeds/blog/atom.xml [L] But that gave me an infinite redirect (maybe because of the preceding rule?). So then I tried this set: RewriteEngine On # Rewrite monkey-robot.com to www.monkey-robot.com RewriteCond %{HTTP_HOST} ^monkey-robot\.com$ RewriteRule ^(.*)$ http://www.monkey-robot.com/$1 [R=301,L] RewriteRule ^$ /blog/ [L] RewriteRule ^blog/?$ http://www.monkey-robot.com/ [R,L] RewriteRule ^feeds/blog/?$ /feeds/blog/atom.xml [L] But I got a 500 Internal Server Error with the following log message: Invalid command '[R,L]', perhaps misspelled or defined by a module not included in the server configuration What gives? I don't think [R,L] is a syntax error.

• Defeating the RAID5 write hole with ZFS (but not RAID-Z) [closed]

  - by Michael Shick

  I'm setting up a long-term storage system for keeping personal backups and archives. I plan to have RAID5 starting with a relatively small array and adding devices over time to expand storage. I may also want to convert to RAID6 down the road when the array gets large. Linux md is a perfect fit for this use case since it allows both of the changes I want on a live array and performance isn't at all important. Low cost is also great. Now, I also want to defend against file corruption, so it looked like a RAID-Z1 would be a good fit, but evidently I would only be able to add additional RAID5 (RAID-Z1) sets at a time rather than individual drives. I want to be able to add drives one at a time, and I don't want to have to give up another device for parity with every expansion. So at this point, it looks like I'll be using a plain ZFS filesystem on top of an md RAID5 array. That brings me to my primary question: Will ZFS be able to correct or at least detect corruption resulting from the RAID5 write hole? Additionally, any other caveats or advice for such a set up is welcome. I'll probably be using Debian, but I'll definitely be using Linux since I'm familiar with it, so that means only as new a version of ZFS as is available for Linux (via ZFS-FUSE or so).

• Internal and External DNS from Different Servers, Same Zone

  - by Shane

  Hello All, I am either having trouble understanding how DNS works, or I am having trouble configuring my DNS correctly (either one isn't good). I am currently working with a domain, I'll call it webdomain.com, and I need to allow all of our internal users to get out to dotster to get our public DNS entries just like the rest of the world. Then, on top of that, I want to be able to supply just a few override DNS entries for testing servers and equipment that is not available publically. As an example: public.webdomain.com - should get this from dotster outside.webdomain.com - should get this from dotster as well testing.webdomain.com - should get this from my internal dns controller The problem that I seem to be running into at every turn is that if I have an internal DNS controller that contains a zone for webdomain.com then I can get my specified internal entries but never get anything from the public DNS server. This holds true regardless of the type of DNS server I use also--I have tried both a Linux Bind9 and a Windows 2008 Domain Controller. I guess my big question is: am I being unreasonable to think that a system should be able to check my specified internal DNS and in the case where a requested entry doesn't exist it should fail over to the specified public dns server -OR- is this just not the way DNS works and I am lost in the sauce? It seems like it should be as simple as telling my internal DNS server to forward any requests that it can't fulfill to dotster, but that doesn't seem to work. Could this be a firewall issue? Thanks in advance

• Error loading operating system: format Windows 7 to Windows XP Service Pack 3

  - by Blerta

  I saw that there are other questions like mine here. But O also saw that some problems where solved with fixmbr from a Windows 7 recovery console, but that didn't work for me. I bought my laptop with Vista installed and later reformated and used Windows 7. During formatting with Windows 7 I had some problems with my hard drive and found out it was dead so I bought a new one. I wanted to reformat with Windows XP,because Windows 7 is consuming more RAM that it is able handle and I wanted to use it for other programs. So I formatted with Windows XP Service Pack 3 but after first reboot a message appeared: "Error loading operating system" Reading here, I assumed that maybe I had installed it on the wrong partition and maybe having two OS now, so I used fixmbr but it is still not starting up. Anyway I am sure that is not the case of two operating systems. Is there any chance that when the computer designed to work with Vista you would face problems with Windows XP? Like not recognizing a hard drive?

• Maxtor 500GB external hard drive not being detected but power is going to it?

  - by ClarkeyBoy

  I have 2 * Maxtor Onetouch 4 Lite 500GB external hard drives (part no. 9NT2A4-500). They both used to work fine on my old laptop (an Acer) but I have not used them for about a year, since my laptop was stolen and I got this one (also an Acer [Aspire 7738G]). I have one plugged into the mains with one of the leads I believe was supplied with them. It appears to be receiving power as it is warm and the power light (on the unit itself) is on; also the mains adapter is fairly warm. I also have it plugged into my laptop with a USB lead which I have tested on my mp3 player (so I know it works). However my hard drive is not showing on my computer. I have tried checking for new hardware, installing the software that was supplied with it, checking drive letters in case it is registered as C: or something stupid, checking for problems etc... I can't find any cause for it to do this. It does appear to be starting up and, possibly, shutting down and restarting constantly (that's what it sounds like altho I can't be certain). I have had both hard drives stored in different places for the last year and they're both doing the same thing.. if it was only one then I'd guess it had got damaged or corrupted or something but since it is both I doubt this is it. The only things in common with both of them are the leads and the laptop, however I know the USB lead works and guess the mains lead works as there is power going to the unit. Has anyone come across this before or does anyone have any idea what the cause / solution to the problem is? Any help would be greatly appreciated. Regards, Richard

• How do I find information about a particular trojan? "W32/Smalltroj.XVGT", as reported by Norman

  - by Lasse V. Karlsen

  I tried checking the Norman antivirus page, Virus-descriptions, but sadly it seems Norman has intentionally obfuscated their search results (I tried clicking on W, and it seems they just list viruses with a W somewhere in the description, instead of more typical, all viruses with a name starting with a W.) Is there a common virus-list somewhere, or is it as I suspect, every antivirus manufacturer is free to come up with their own identification tags for each virus? Several "vshost32.exe" files, related to Microsoft Visual Studio 2008, has been quarantined on our server today, probably related to a test-deployment of some internal software. Some developer machines that have grabbed that latest version of our program has also had the same files quarantined. Now, these files should not have been deployed in the first case, so I'll be looking into that, but whenever any developer now builds a program locally and attempts to debug, the same file is placed in the build output directory, and promptly quarantined. Does anyone have any clues as to how I can go about verifying this before I pointedly ask the antivirus software to go take a hike on this particular virus? Edit: I've copied one of the quarantined files manually to a machine over the network that doesn't have antivirus installed, and compared the file on that machine with a local copy (on that machine) of the vshost32.exe template file, and they're bit-for-bit identical. I guess this is a false positive. I still would like to know if it would be possible for me to verify this in any other way though, since next time such a trojan might be reported in a compiled file that we won't have a pristine copy of.

• What speed are Wi-Fi management and control frames sent at?

  - by Bryce Thomas

  There are a bunch of different 802.11 Wi-Fi standards, e.g. 802.11a, 802.11b, 802.11g, 802.11n etc. that all support different speeds. Wi-Fi frames are generally categorised as one of the following: Data frames - carry the actual application data Control frames - coordinate when its safe to send/reduce collisions Management frames - handle connection discovery/setup/tear down (e.g. AP discovery, association, disassociation) My question is about whether all these frames, and specifically management frames, are transmitted at the fastest supported speed available, or whether certain classes of frames are transmitted at some lowest common denominator speed. I have noticed that when I put an 802.11b/g only device into monitor mode and capture traffic over the air, I still see management frames (e.g. association/disassociation) being transmitted between my phone and AP which are both 802.11n, even though 802.11n has a higher transfer rate. So I am imagining one of two possibilities: My 802.11n phone/AP had to negotiate a slower speed for some reason and that's why I can see their frames on my 802.11b/g monitoring device. Management frames (and perhaps control frames also?) are sent at a lower speed, and it's only data frames that are transmitted faster with newer 802.11 standards. The reason I would like to know which one of these two possibilities (or perhaps a third possibility) is the case is that I want to capture management frames, and need to know whether using an 802.11b/g card is going to lead to me missing some frames sent at higher speeds than the monitoring card can observe. If management frames are indeed sent at a slower rate, then it's all good. If I just happen to be seeing the management frames because my phone/AP have negotiated a slower rate though, then I need to reconsider what card I use for packet capture.

• How do I know what hardware to buy to meet my needs?

  - by Darth Android

  While Stack Exchange does not permit shopping recommendations, it doesn't provide any general advice to consider when buying hardware. So, instead of just telling those that ask what to buy that it's not allowed, let's tell them how to figure out what they need. When looking forward to build a computer, how do I know what to buy? How do I find out if a given CPU will be enough for a certain game or application that I want to run? How do I find out if a given graphics card will be enough for a certain game or application? What is important when looking at motherboards? How much memory do I need? How do I know how much wattage I need for a power supply? What size case do I need? What relevant standards do I need to read up on and be aware of? PCI, PCIe, SATA, USB 2.0, USB 3.0, etc... What "gotchas" do I need to be on the lookout for? Please keep responses generation-agnostic to ensure they will be helpful to our future users. :)

• PGB Multipath & return routes

  - by Dennis van der Stelt

  I'm probably a complete n00b concerning serverfault related questions, but our IT department makes a bold statement I wish to verify. I've searched the internet, but can find nothing related to my question, so I come here. We have Threat Management Gateway 2010 and we used to just route the request to IIS and it contained the ip address so we could see where it was coming from. But now they turned on "Requests apear to come the TMG server" so ip addresses aren't forwarded anymore. Every request has the ip of the TMG server. Now the idea behind this is that because of multipath bgp routes, the incoming request goes over RouteA, but the acknowledgement messages could return over RouteB. The claim is that because the request doesn't come from the first known source, our proxy, but instead from IIS, some smart routers at the visitor of our websites don't recognize the acknowledgement message and filter it out. In other words, the response never arrives. Again, this is the claim. But I cannot find ANY resources on the internet that support this claim. I do read about pgb multipath, but more in the case that there are alternative routes when the fastest route fails for some reason. So is the claim completely bogus or is there (some) truth to it? Can someone explain or point me to resources? Thanks in advance!

• Java applet class never found

  - by Andrew

  I am having a problem with the java plugins of all three major browsers: chromium, firefox and Internet Explorer. The issue is that applets will always fail to load and yield errors no matter what website or what applet I am trying to use. I can not see any of the example applets on oracle's website; I can not launch the minecraft browser applet; nor can I launch any applet across the web using any browser. I always receive a "class not found:AppletClassHere.class" error. I know that my browser plugin must be working correctly because I can launch the Cisco Nac applet each time I connect to my network and I can launch my own simple applets offline. I am connecting to the internet through a vpn in case that is important. It also seems like a lot of other people I know are having this issue. Re-installing the plugin does not appear to fix the issue. I am asking this question to find out the cause of this problem, and any possible solutions. Thank you.

• How can I tell if a replacement display is compatible with my laptop?

  - by moraleida

  I have an Acer Aspire 4810TZ from 2010 which I truly love - it's a 3 year old notebook that still carries on for about 5 to 6h straight off the battery. I've also invested in it with an SSD and extra RAM and it's fine for my use right now. I'd really rather not just dump it. Now... its screen is dead and I'm looking for replacement parts, but it turns out to be a kind of expensive display - AUO B140XW02 14" LED. US$ 125 was the cheapest I found here (Rio de Janeiro, Brazil). The official dealer sells them for US$ 175. I'm aware of How do I know if a LCD is compatible with my Laptop? and Can I replace a laptop screen with one of a different resolution? but the answers don't really help me in this case. Also Replacing an LCD screen in a laptop gives me a hint but I'm completely dumb at hardware so this is why i'm asking: Is it possible to buy an LCD or a lower grade LED screen with the same connectors? What characteristics should I look for to find out if a certain display is compatible?

• Why can't I install Java?

  - by Patrick

  I've been searching high and low for someone who can help me. I've been trying for a month. A month. to install Java on my new PC to no avail. No tech support forum can seem to help me. It all started while playing tekkit one day. I kept running out of memory (using the 32-bit JRE 7 u45) so I decided to install the 64-bit version. I uninstalled the 32-bit version first, for some reason, and downloaded the 64 bit runtime. In the installer, I go through all the normal screens until the installation progress bar appears. Then, it just sits there. No progress is made. No CPU is used by the installer, or any of its dependencies. The installer will stay like this for hours, days, and in one case a whole week without doing anything at all. I've tried installing older versions, the 32-bit version, even Java 6 and none of them will install. UAC is disabled, I've run regedit, CCleaner, and any other "fix-it" program there is. It's getting to the point where I may just have to wipe my hard drives and start over. I have several applications that require java, so this is an absolute necessity. Please, please, someone have the answer. Here are my system specs: -Intel i7-3770k -AsRock z77 Extreme3 -Samsung 840 pro SSD -WD Caviar Black 1tb

• Moving Farm to co-location hosting - network settings requirements

  - by Saariko

  I am moving my farm (2 Dell's R620) to a co-location hosting service. I am trying to figure out the secure way to have my network settings The requirements are: VM1 is the working HOST, includes: esxi 5.1, vSphere, 4 clients (w2008r2 all) VM2 has esxi 5.1 installed, and a single machine with Veeam Backup and copy 6.5 - keeping a copy of VM1 clients on the VM2 internal storage (this solution is due to a very small budget - in case of failure on Host 1 - can redirect IP's) Only 2 VM clients require network address and access from the WWAN - ISP provides IP's range for them (with Gateway and DNS) I need connection to the iDrac's from my office (option to create a VPN-SSL tunnel) Connection to the vSphere appliances I want to be able to RDP to the VM clients The current configuration is that each host has the iDrac dedicated nic connected , and another (NIC #1) connected - with a static IP on 192.168.3.x The iDrac's have a static IP from the same network range (19.168.3.x) It will look something like this: My thoughts: On NIC#2 of both hosts I will connected a crossed cable I will give each VM clients that needs internet access a 2ndry VM network with the assigned IP from the ISP open only to web - can not access from the My Question: Should I give IP's (external) to the machines who DO NOT require WWAN Access? - I can't see a way to RDP to them directly if not. Should I use the crossed cable? or just plug NIC #2 to the switch? Will this setup even work? What do I need to verify? What Virtual nic's and/or switches should I create on the Hosts?

• Datacenter IP Addressing and DNS Management

  - by user65248

  Hello everyone Basically we are setting up a small Datacenter, about 300 amps power and max 50 racks, Im saying these coz I wanna u imagine the size and requirements, I have studied networking mostly Microsoft and Windows based systems , but I cant get how the IP addressing and DNS management and configuration works in a Datacenter , and unfortunately I have to setup everything by myself but defe we will have some staff to do some job. Now my questions Datacenter IP Addressing Suppose we have got a block of 200 IP addresses from our ISP, How can I manage these block of IP addresses, is there any software out there to simplify this I heard that using DHCP server in a datacenter is not recommended, otherwise what would u say about MS DHCL server ofc considering we need to have backup serversin case of failur How can I assign a block of IPs to a specific rack, I know with different software and management its different but Im asking how it is done normally IP addresses are exposed to the whole network, what if a customer try to use an IP address and is not assigned to their server or rack , how can I prevent this or how can I track the IP usage DNS Management Im goin to setup at least two servers for our DNS servers, I know nothing about Datacenter DNS system, but I have configured DNS server in normal networks and also for webservers, Now I wanna know What exactly needs to be done for a DNS in a datacenter that is not done for normal networks. How can I configure PTR records why cant I configure PTR records on my webserver side DNS server and it should be done on datacenter DNS server , I mean what is the difference in DC DNS servers that allow us to to so , I know the question is very silly and simple but Im confused Is there any software outthere to allow doing the whole thing, I mean automatically add records to the DNS and also managin IP addresses !? Thanks in advance

• Missing Data on VMWare Virtual Disk

  - by Lachlan McDonald

  Evening all, I've got a considerable problem I'm hoping to get some resolution on. I had two VMWare 6.5 virtual machines, one running Ubuntu 9.10 and the other Ubuntu 10.04. I used 9.10 as a testing server, so I could install a LAMP environment to prepare some code. Over the months I took a number of snapshots of this VM just in case something went wrong, and did a full copy of the entire VM a month ago. I created the 10.04 VM when Lucid Lynx launched so I could continue development on a fresh install. To get the files over, I simply added the 9.10 virtual disk into the 10.04 VM, grabbed some of the files I needed, and dismounted it. Unknown to me at the time, the changes to the 9.04 virtual disk meant that I could no longer boot it with the 9.10 VM. I'd always get the "The parent virtual disk has been modified since the child was created." error. I decided this was a good time to backup all the critical files, but now whenever I open the 9.04 disk to get the data it isn't in the same state as it was earlier. My question is; is it possible when I'm mounting the virtual disk that I'm not seeing the most recent snapshot, or in my blundering, have I lost the virtual disk. Cheers

• Find and Replace several several different values all at once

  - by matt

  I have a file with multiple instances of Text_1 and Text1 and I need to replace both those strings with Text_A and TextB respectively. Currently I'm doing two Find and Replace functions on each file one that finds Text_1 and replaces it with Text_A and the other that finds Text1 and replaces it with TextB. Is there any way to do this all at once instead of having to run "Find and Replace" twice? I am using Dreamweaver CS3, but I also have Notepad++, regular Notepad, OO Writer, MS Word if those will be easier. Ideally I could do this in Dreamweaver or Notepad++ but I'm open to downloading something else to get the job done. I'd prefer not to have to do any command line stuff or create a batch file (while I'm aware of it, I don't understand it really). Edit: In case the above description isn't clear, let me explain it this way... I want to run Find & Replace 1 time in 1 document and I want it to do ALL of the following during that one Find & Replace instance: Find: Text_1 and Replace with: Text_A Find: Text1 and Replace with: TextB I am not trying to do a Find and Replace across several documents.

• what web based tool, to allow a non-technical user to manage authorized keys files on a Linux (fedora/centos/ubuntu/debian) server

  - by Tom H

  (Edit: clarification below) We have a number of groups of developers that change frequently, and a security policy to require individual logins to servers using rsa or dsa public keys, which is achieved via the standard method of adding id_dsa.pub to their authorized keys file. I am using chef to sync the user accounts across machines, however our previous method of using webmin to manage the user passwords is not designed for key based auth, and hence is not easy to use for non-technical users. The developers are logging in from the WAN using ssh, they can either provide their own key, or an administrator will send them a private key. The development machines are located in the cloud and we have a single server available to host the master set of accounts. Obviously I could deploy ldap or other centralised authentication system, but that seems a bit over blown when webmin worked well for the simple case. It is easy to achieve synchronised users, groups and passwords across a bunch of low security development boxes using webmin clustered users and groups. However looking at the currently installed webmin it is not so easy to create the authorized keys as it is to create user accounts and passwords. (its possible, but its not easy - some functionality is in the usermin module, or would required some tedious steps) Ideally I'd like a web interface that is pretty much dedicated to creating users and groups, and can generate key pairs on the fly, and can accepted pasted in public keys to add to the users authorized keys file. If the tool sync'ed the users and keys as well, that would be great, but I can use chef to do that part if the accounts are created correctly on the "master" server.

• I/O APIC on Virtualbox

  - by RidDeBakTiYar

  I'm trying to use the PIT to do APIC timer calibration, and I want to use the PIT through I/O APIC instead of PIC. On Bochs I get interrupts from the PIT at the asked frequency from the I/O APIC, while on Virtualbox I can't receive a single interrupt. It must be an I/O APIC configuration problem because as I unmask the first PIC entry, the IRQ fires. However that's not what I want. Can you imagine any possible condition that wouldn't make Virtualbox fire the IRQ? I'm not assuming single I/O APIC configuration (even though Virtualbox has only 1). I'm not assuming identity mappings between ISA IRQs and I/O APIC GSIs (using ACPI MADT table to get I/O APIC base address and Int override). I'm setting the Trigger Mode and Polarity bits correctly (on Virtualbox they are set as '00 - default' which means edge high right?). I'm putting the BSP APIC ID into the Destination field (using Physical destination) and vector 0x20. Being the BSP APIC ID 0 on Virtualbox, it ends up with 0x0000000000000020 written to the IOREDTBL. And, just in case I'm getting the wrong values from the Interrupt Override descriptor, I'm setting this value to all the IOREDTBL entries (I know this is very very bad, and it wont be kept as I understand what's going on). The only thing I didn't check out is Local APIC configuration. Actually I'm not writing any value to the BSP LAPIC. Just reading the APIC ID and using it to boot APs through IPIs. And obviously I'm setting bit 11 in the IA32_APIC_BASE MSR to enable the LAPIC. Any ideas? Thanks in advance.

• How use DNS server to create simple HA (High availability) of my website?

  - by marc22

  Welcome, How can i use DNS server to create simple HA (High availability) of website ? For example if my web-server ( for better understanding i use internal IP in real it will be other hosting companies) 192.168.0.120 :80 (is offline) traffic go to 192.168.0.130 :80 You have right, i use bad word "hight avability" of course i was thinking about failover. Using few IP in A records is good for simple load-balancing. But not in case, if i want notice user about failure (for example display page, Oops something is wrong without our server, we working on it) against "can't establish connection". I was thinking about setting up something like this 2 DNS servers, one installed on www server Both have low TTL on my domain, set up 2 ns records first for DNS with my apache server second to other dns If user try connect he will get ip of www server using first dns, if that dns is offline (probably www server is also down) so it will try second NS record, what will point to another dns, that dns will point to "backup" page. That's what i would like to do. If You have other idea please share. Reverse proxy is not option, because IP of server can change, or i can use other country for backup.

  - by Joe Schmoe

  Since I've been using my laptop more as a laptop recently (carrying it around) I am now evaluating my strategy to protect confidential information in case it is stolen. Keep in mind that my laptop is 6 years old (Lenovo T61 with 8 GB or RAM, 2GHz dual core CPU). It runs Windows 7 fine but it is no speedy demon. It doesn't support AES instruction set. I've been using TrueCrypt volume mounted on demand for really important stuff like financial statements forever. Nothing else is encrypted. I just finished my evaluation of EFS, Bitlocker and took a closer look at TrueCrypt again. I've come to conclusion that boot partition encryption via Bitlocker or TrueCrypt is not worth the hassle. I may decide in the future to use Bitlocker or TrueCrypt to encrypt one of the data volumes but at this point I intend to use EFS to encrypt parts of my hard drive that contain data that I wouldn't want exposed. The purpose of this post is to get your feedback about what folders should be encrypted from the general point of view (of course everyone will have something specific in addition) Here is what I thought of so far (will update if I think of something else): 1) AppData\Local\Microsoft\Outlook - Outlook files 2) AppData\Local\Thunderbird\Profiles and AppData\Roaming\Thunderbird\Profiles- Thunderbird profiles, not sure yet where exactly data is stored. 3) AppData\Roaming\Mozilla\Firefox\Profiles\djdsakdjh.default\bookmarkbackups - Firefox bookmark backup. Is there a separate location for "main" Firefox bookmark file? I haven't figured it out yet. 4) Bookmarks for Chrome (don't know where it's bookmarks are) and Internet Explorer ($Username\Favorites) - I don't really use them but why not to secure that as well. 5) Downloads\, My Documents\ and My Pictures\ folders I don't think I need to encrypt, say, latest service pack for Visual Studio. So I will probably create subfolder called "Secure" in all of these folders and set it to "Encrypted". Anything sensitive I will save in this folder. Any other suggestions? Again, this is from the point of view of your "regular office user".

• Mac Mini drive problems but SMART verified: bad hard drive or controller?

  - by Zac Thompson

  I have a 3-year-old Intel Mac Mini at home. About a month ago, it stopped booting from the hard drive (internal, SATA, 80GB). I tried booting from the Install Disc to repair the filesystem but Disk Utility was unable to do so ("invalid node structure"). I was also unable to use the hard drive in the Terminal from the Install Disc nor from an Ubuntu boot CD ("DRDY err"). I could see the contents of some directories, but others would give an error and I would get failures when trying to copy files. At this point I was sure the filesystem was hosed and I'd want to reformat at least. DiskWarrior was able to let me retrieve the data files I was interested in, which are now copied to an external hard drive, but it reported a high number of problems ("speed reduced by disk malfunction" count was over 2000) when in the process of trying to rebuild the directory for the drive. It also would not let me use the rebuilt directory to replace the one on the drive; it claimed the disk errors prevented recovery in this way. Under normal circumstances I would now assume that the drive itself was going bad: DiskWarrior's "disk malfunction" error above is supposed to imply hardware problems. My initial plan was to buy a replacement for the internal 2.5" drive. However: Disk Utility, command-line tools and DiskWarrior had reported all along that the SMART status of the drive was okay/Verified. So I'm now worried that the drive hardware is actually fine, and that the problems were due to a disk controller that has gone "bad" somehow. If this is the case, I'll probably just replace the whole computer. Any advice on how I can tell what is to blame? I don't have a lot of extra hardware sitting around, so I don't have the option of simply dropping the drive in another machine or popping another hard drive inside the Mini.

• Firefox does not upgrade properly (infinite installation loop without success)

  - by Mehper C. Palavuzlar

  I've been using Firefox for a long time but I have a problem with upgrading process now. As you know, Firefox automatically checks for the latest version and downloads it, and when it is ready to be installed it starts the installation process as usual. Last month, when I clicked on "OK, install v3.6.2", the process started but couldn't be finished properly. FF gave a message like that: "Installation cannot be completed, please restart Firefox to retry". When I restarted FF, the same thing happened, and the process entered in an infinite loop. I restarted my PC and clicked on FF icon, and again the installation process began and went into the infinite loop. My solution to this problem was to download FF 3.6.2 and manually install it after killing firefox.exe. Today, FF proposed me to install v3.6.3 and again the same problem occured. I manually downloaded FF 3.6.3 and installed it successfully. Anyone experiencing this problem? In case you want to know, I did not install any new addons in the last few months, and my FF operates without problems. I'm using Windows 7 Home Pro x64.

• Join mp4 files in linux

  - by Jose Armando

  I want to join two mp4 files to create a single one. The video streams are encoded in h264 and the audio in aac. I can not re-encode the videos to another format due to computational reasons. Also, I cannot use any gui programs, all processing must be performed with linux command line utilities. FFmpeg cannot do this for mpeg4 files so instead I used MP4Box e.g. MP4Box -add video1.mp4 -cat video2.mp4 newvideo.mp4 unfortunately the audio gets all mixed up. I thought that the problem was that the audio was in aac so I transcoded it in mp3 and used again MP4Box. In this case the audio is fine for the first half of newvideo.mp4 (corresponding to video1.mp4) but then their is no audio and I cannot navigate in the video also. My next thought was that the audio and video streams had some small discrepancies in their lengths that I should fix. So for each input video I splitted the video and audio streams and then joined them with the -shortest option in ffmpeg. thus for the first video I ran avconv -y -i video1.mp4 -c copy -map 0:0 videostream1.mp4 avconv -y -i video1.mp4 -c copy -map 0:1 audiostream1.m4a avconv -y -i videostream1.mp4 -i audiostream1.m4a -c copy -shortest video1_aligned.mp4 similarly for the second video and then used MP4Box as previously. Unfortunately this didn't work either. The only success I had was when I joined the video streams separetely (i.e. videostream1.mp4 and videostream2.mp4) and the audio streams (i.e. audiostream1.m4a and audiostream2.m4a) and then joined the video and audio in a final file. However, the synchronization is lost for the second half of the video. Concretelly, there is a 1 sec delay of audio and video. Any suggestions are really welcome.
