  • Strange performance differences in read/write from/to USB flash drive

    - by Mario De Schaepmeester
    When copying files from my 8GB USB 2.0 flash drive with Windows 7 to a traditional hard drive, the average speed is between 25 and 30 MB/s. When doing the reverse, copying to the USB drive, the speed is 5MB/s average. I have tested this with about 4.5GB of files, a mixture of smaller and larger ones. The observations were the same on both FAT32 and exFAT file systems on the USB drive, NTFS on the internal hard disk. I don't think I can be mistaken in saying that flash memory has a lot higher performance than a spinning hard drive in both terms of reading and writing. For both memory types, reading should be faster than writing too. Now I wonder, how can it be that copying files from a fast read memory to a faster write memory is actually slower than copying files from a fast read memory to a slow write memory? I think that the files are stored in RAM before being copied over too, and there's caching as well, but I don't see how even that could tip the balance. It can only be in the advantage of writing to the USB drive, since it is "closer" to the SATA system than the USB port and it will receive data from the internal SATA HDD faster. Perhaps my way of thinking is all wrong or it just depends on the manufacturer of the USB pen. But I am curious.

  • LDAP search filter for Active Directory

    - by Francesco De Vittori
    Hello, I'm trying to look for users inside Active Directory through a LDAP query. Basically I'm searching for the user in this way: Search DN: dc=mydomain, dc=com Filter: (sAMAccountName=USER) where USER is replaced with the provided username. Now if USER is only the username without domain (for ex. "Joe") this works fine. However I receive them in the form (domain\username, for ex. "myDomain\Joe") and obviously the search fails. I see two ways: using a regex inside the Search Filter to discard the domain using a completely different search filter I'm no LDAP expert and I don't even know if it's possible to use regular expressions inside the search filters. Does anyone know if it's possible and how? P.S. I cannot pre-process the username to strip the domain. This cannot be changed, as it's all part of a large system.

  • Is there a test to see if hardware virtualization (vmx / xvm) are presently enabled within a Linux session?

    - by Dr. Edward Morbius
    I'm writing procedures for configuring VirtualBox support for 64-bit SMP guests, which requires hardware virtualization suppot (VTx/Intel, AMD-V/AMD). I have successfully configured this myself, however I'd like the procedure to be clear. sed -ne '/^flags/s/^.*: //p' /proc/cpuinfo | egrep -q '(vmx|svm)' && echo Has hardware virt || echo No HW virt ... shows if the CPU is capable. I've still got to go enable the feature in BIOS. Any way to test from within Linux to see that this is no or not? Thanks.

  • Can Mac KeyNote presentations exported for Windows be shown in good quality and be edited?

    - by Edward Tanguay
    A friend asked me this: ...I stopped using KeyNote for one simple reason – contrary to the Mac marketing blurb, the final presentations do NOT work fine on Windows PCs – they look distorted and have formatting quirks which cannot be corrected because the Windows/Powerpoint file it has supposedly been saved as is in fact a non-editable file, kind of like a pdf. Is there a way to create Mac KeyNote presentation files so they look nice on Windows and can be edited?

  • Can someone explain RAID-0 in plain English?

    - by Edward Tanguay
    I've heard about and read about RAID throughout the years and understand it theoretically as a way to help e.g. server PCs reduce the chance of data loss, but now I am buying a new PC which I want to be as fast as possible and have learned that having two drives can considerably increase the perceived performance of your machine. In the question Recommendations for hard drive performance boost, the author says he is going to RAID-0 two 7200 RPM drives together. What does this mean in practical terms for me with Windows 7 installed, e.g. can I buy two drives, go into the device manager and "raid-0 them together"? I am not a network administrator or a hardware guy, I'm just a developer who is going to have a computer store build me a super fast machine next week. I can read the wikipedia page on RAID but it is just way too many trees and not enough forest to help me build a faster PC: RAID-0: "Striped set without parity" or "Striping". Provides improved performance and additional storage but no redundancy or fault tolerance. Because there is no redundancy, this level is not actually a Redundant Array of Inexpensive Disks, i.e. not true RAID. However, because of the similarities to RAID (especially the need for a controller to distribute data across multiple disks), simple strip sets are normally referred to as RAID 0. Any disk failure destroys the array, which has greater consequences with more disks in the array (at a minimum, catastrophic data loss is twice as severe compared to single drives without RAID). A single disk failure destroys the entire array because when data is written to a RAID 0 drive, the data is broken into fragments. The number of fragments is dictated by the number of disks in the array. The fragments are written to their respective disks simultaneously on the same sector. This allows smaller sections of the entire chunk of data to be read off the drive in parallel, increasing bandwidth. RAID 0 does not implement error checking so any error is unrecoverable. More disks in the array means higher bandwidth, but greater risk of data loss. So in plain English, how can "RAID-0" help me build a faster Windows-7 PC that I am going to order next week?

  • Cloudstack virtual machines can't communicate with virtual routers when they are on different hosts

    - by Jorge Suárez de Lis
    I'm using Cloudstack 2.2.14 on a Ubuntu 10.04 set of hosts, and I have a problem on my setup. I have two hosts running. When a virtual router is created on host 1 and a virtual machine using that virtual router is created on host 2, or vice versa, I have no connectivity at all on the virtual machine. First of all, I have to setup the network manually on that virtual machine -usually DHCP is working, but not here-. Then, I can't ping to the virtual router from the virtual machine or vice versa. When both virtual router and virtual machine are created on the same host, everything works! Maybe those packages are being filtered somehow? I have no clue on how to proceed. Both hosts can communicate directly outside the virtualization.

  • Where to begin with IPv6 [closed]

    - by Willem de Vries
    I am fairly familiar with setting-up IPv4 networks for bigger server configurations, only now I wanted to start familiarizing myself with doing the same for IPv6. I have been Googling for the second night in a row for things like: IPv6 network design, IPv6 for dummies, etc. So far most things you find go on about why IPv6 and the amazing amount of numbers that we have now. Yet I am looking for practical stuff, for example: what would be a good way to assign IP-number, as I understand it DHCP shouldn't be the default course of action. How do other assignment methods work with DNS configuration? what would be a good or standard way of dividing the network in to sub-nets? (database, application, web servers spread over multiple domains/applications and some what intertwined) In short I would like to find good resources with practical information books, webpages, etc.

  • Where is the "fix" button on Windows 7 Photo Viewer?

    - by Edward Tanguay
    When I click on a photo in Vista I get a fix button: When I click on a photo in Windows 7 I don't get a fix button: I used to use this fix button often to fix red-eye and alter the brightness quickly, and the auto-saving was so fast. If I can't get "Windows Photo Viewer" to do this, I'll have to http://www.irfanview.com again to do this.

  • Why would image thumbnails not be showing in all search engines in all browsers?

    - by Edward Tanguay
    For over a week now, when I search for a word at Google, it correctly gives me some preview image thumbnails: But when I click on "images", it doesn't show me any thumbnails: The same thing happens at Bing.com, when I search Bing itself it gives me some thumbnails on the general search result page: But when I click on "images", it doesn't show me any thumbnails: The same thing happens at Yahoo: If I click on one of the broken thumbnails, it shows me the picture fine: Thumbnails at youtube also work fine: It seems each search engine is hanging on different URLs as shown above: t1.gstatic.com ts3.mm.bing.net thm-a02.yimg.com so it doesn't seem to be the problem of one specific URL not sending thumbnails, it is just a problem with search engine image thumbnails in general. Also, this happens in every browser I try: Explorer, Firefox, Chrome. What could be the problem? Is it my computer, some setting somewhere, my router, my Internet provider (T-Online, Germany)? Has anyone ever had this problem and solved it?

  • How do I configure Thunderbird to locally remap the label-folder in an G-Mail IMAP account?

    - by Edward Beach
    I'm using G-Mail and Thunderbird together for an imap account. One of the limitations of G-Mail is that there's no concept of nested labels - which is fine when I'm using the account through the web interface but when I'm using Thunderbird I would like a bit more organization. Is there a way for Thunderbird to locally remap an imap folder's path? For example with a "MyCustomLabel" label: Thunderbird: "MyAccount/path/on/local/machine/MyCustomLabel" G-Mail: "MyCustomLabel" Thanks

  • What is the easiest way to get a yyyy-mm-dd hh:mm:ss timestamp hotkey on the Mac?

    - by Edward Tanguay
    On Windows I use the PSPad editor which has a nice ALT-D timestamp which you can edit the format of, e.g. yyyy-mm-dd hh:mm:ss. When working outside an editor, e.g. Google Docs, I have Autohotkey which I have programmed CTRL-D to insert a yyyy-mm-dd hh:mm:ss timestamp. I am now working on a Mac mostly using TextWrangler as my editor but I can't find a timestamp hotkey in its features. What is the easiest way to get a yyyy-mm-dd hh:mm:ss hotkey on Mac, either in a (free) text editor or a (free) autohotkey equivalent?

  • Memory usage on debian webserver keeps going up

    - by Steven De Groote
    my webserver is running apache 1.3.x for a PHP application, along with mysql on the same machine. Most of the time it runs fine, CPU usage still with nice margin, but somehow memory usage keeps growing throughout uptime. While it looks like it is chunked from time to time, I've had moments my server going down because it's out of memory. Restarting apache or mysql only reduced memusage by 100M. Attached is an overview of monthly memory usage. The 2 massive drops are server restarts after out-of-memory situations. http://imageshack.us/photo/my-images/51/memorymonth.png/ Any explanations for his behaviour or how I could solve this? Thanks!

  • Enabling mod_rewrite on Amazon Linux

    - by L. De Leo
    I'm trying to enable mod_rewrite on an Amazon Linux instance. My Directory directives look like this: <Directory /> Order deny,allow Allow from all Options None AllowOverride None </Directory> <Directory "/var/www/vhosts"> Order allow,deny Allow from all Options None AllowOverride All </Directory> And then further down in httpd.conf I have the LoadModule directive: ... other modules... #LoadModule substitute_module modules/mod_substitute.so LoadModule rewrite_module modules/mod_rewrite.so #LoadModule proxy_module modules/mod_proxy.so ... other modules... I have commented out all the Apache modules not needed by Wordpress. Still when I issue http restart and then check the loaded modules with /usr/sbin/httpd -l I get only: [root@foobar]# /usr/sbin/httpd -l Compiled in modules: core.c prefork.c http_core.c mod_so.c Inside the virtual host containing the Wordpress site I have an .htaccess containing: # BEGIN WordPress <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> # END WordPress The .htaccess is owned by apache which is the user apache runs under. The apachectl -t command returns Syntax OK What am I doing wrong? What should I check?

  • Xen and HyperVM build question on os template

    - by Levi De Haan
    I recently built a server with hypervm and xen, now i know xen from command line, but hypervm ties into our whmcs and so its a requirement, however my question is this, when i build a new o/s template my partition table is gone, and i know why, but i was wondering if anyone has built anything in hypervm for adding in partition tables, so i dont have to reinvent the wheel :). i can do it command line in the created vm with fdisk, and i have tracked down the creation scripts for hypervm but i am unsure if these insert directly into the machine as it looks like a lot of the things it does are externalized and are for xen to assign things like ip address etc.. oh and on an aside when i go in to modify the .cnf file to change the boot disk from cdrom to drive on windows when i boot using hypervm it overwrites my setting again..frustrating as heck, i've been trying to track down where in the code it does this, has anyone else had this problem and if so how did you fix it if you did?

  • EFI vs MBR - Installing Windows Server 2008 R2 or 2012 on 8TB

    - by Riaan de Lange
    I'm having some difficulty installing Windows Server 2008 R2 and Windows Server 2012 on an Intel Server platform. The server specs is as follows: Intel Grizzly Pass Server System - R2308GZ4GC 2x Intel Xeon 2620 - 2.0 GHZ - BX80621E52620 132 GB of Memory REG-DIMM - TS1GKR72V6H 4x Seagate Constellation ES 2TB 3.5" 7200rpm 6GB/S - ST32000645NS Intel Big Laurel 4CH 6G SAS RAID 512MB - RS2BL040 On the Intel RAID Controller Setup, I have setup the HDD to be in RAID-0 - for testing purposes. (Ultimately configured in RAID-5) So, the total size of HDD space I can use is 7.6 TB something... When I install the Server OS's, they don't seem to go beyond 2 TB (1.76 TB) I have read up on EFI and UEFI boot, and this seems to work in 2012, but I could not install any drivers for the motherboard... So, I also tried EFI for 2008R2, and this worked while installing the OS, it did not however work with the Windows Boot Manager option in the BIOS. It kept on freezing once it tries to load the partition. My idea was to allocate the complete 8 TB for the OS, and load a few VM's on there. I have now started with a new approach where I'll have a 256 GB OS Partition, and a secondary 7.5 TB Data partition. Oh, and I also did a diskpart - convert disk to gpt whilst installing 2008R2. The whole disk was accessible, 7.6TB Can anyone please clarify that EFI/UEFI is meant for larger boot volumes? Bigger than 2TB. If I were to have an ideal situation where my OS is run on a SSD, 256GB, and I can attach the 8 TB drives as normal disk to the OS? I'm I correct in saying that if I wanted to boot from a 8TB partition, I would need to force the BIOS to boot from EFI? The limit for MBR is 2 TB as far as I know now... *FYI: The motherboard is EFI-ready

  • libpam-ldapd not looking for secondary groups

    - by Jorge Suárez de Lis
    I'm migrating from libpam-ldap to libpam-ldapd. I'm having some trouble gathering the secondary groups from LDAP. On libpam-ldap, I had this on the /etc/ldap.conf file: nss_schema rfc2307bis nss_base_passwd ou=People,ou=CITIUS,dc=inv,dc=usc,dc=es nss_base_shadow ou=People,ou=CITIUS,dc=inv,dc=usc,dc=es nss_base_group ou=Groups,ou=CITIUS,dc=inv,dc=usc,dc=es nss_map_attribute uniqueMember member The mapping is there because I'm using groupOfNames instead of groupOfUniqueNames LDAP class for groups, so the attribute naming the members is named member instead of uniqueMember. Now, I want to do the same using libpam-ldapd but I can't get it to work. Here's the relevant part of my /etc/nslcd.conf: base passwd ou=People,ou=CITIUS,dc=inv,dc=usc,dc=es base shadow ou=People,ou=CITIUS,dc=inv,dc=usc,dc=es base group ou=Groups,ou=CITIUS,dc=inv,dc=usc,dc=es map group uniqueMember member And this is the debug output from nslcd, when a user is authenticated: nslcd: [8b4567] DEBUG: connection from pid=12090 uid=0 gid=0 nslcd: [8b4567] DEBUG: nslcd_passwd_byuid(4004) nslcd: [8b4567] DEBUG: myldap_search(base="ou=People,ou=CITIUS,dc=inv,dc=usc,dc=es", filter="(&(objectClass=posixAccount)(uidNumber=4004))") nslcd: [8b4567] DEBUG: ldap_initialize(ldap://172.16.54.31/) nslcd: [8b4567] DEBUG: ldap_set_rebind_proc() nslcd: [8b4567] DEBUG: ldap_set_option(LDAP_OPT_PROTOCOL_VERSION,3) nslcd: [8b4567] DEBUG: ldap_set_option(LDAP_OPT_DEREF,0) nslcd: [8b4567] DEBUG: ldap_set_option(LDAP_OPT_TIMELIMIT,10) nslcd: [8b4567] DEBUG: ldap_set_option(LDAP_OPT_TIMEOUT,10) nslcd: [8b4567] DEBUG: ldap_set_option(LDAP_OPT_NETWORK_TIMEOUT,10) nslcd: [8b4567] DEBUG: ldap_set_option(LDAP_OPT_REFERRALS,LDAP_OPT_ON) nslcd: [8b4567] DEBUG: ldap_set_option(LDAP_OPT_RESTART,LDAP_OPT_ON) nslcd: [8b4567] DEBUG: ldap_simple_bind_s("uid=ubuntu,ou=Applications,ou=CITIUS,dc=inv,dc=usc,dc=es","*****") (uri="ldap://172.16.54.31/") nslcd: [8b4567] connected to LDAP server ldap://172.16.54.31/ nslcd: [8b4567] DEBUG: ldap_result(): end of results nslcd: [7b23c6] DEBUG: connection from pid=15906 uid=0 gid=2000 nslcd: [7b23c6] DEBUG: nslcd_pam_authc("jorge.suarez","","su","***") nslcd: [7b23c6] DEBUG: myldap_search(base="ou=People,ou=CITIUS,dc=inv,dc=usc,dc=es", filter="(&(objectClass=posixAccount)(uid=jorge.suarez))") nslcd: [7b23c6] DEBUG: ldap_initialize(ldap://172.16.54.31/) nslcd: [7b23c6] DEBUG: ldap_set_rebind_proc() nslcd: [7b23c6] DEBUG: ldap_set_option(LDAP_OPT_PROTOCOL_VERSION,3) nslcd: [7b23c6] DEBUG: ldap_set_option(LDAP_OPT_DEREF,0) nslcd: [7b23c6] DEBUG: ldap_set_option(LDAP_OPT_TIMELIMIT,10) nslcd: [7b23c6] DEBUG: ldap_set_option(LDAP_OPT_TIMEOUT,10) nslcd: [7b23c6] DEBUG: ldap_set_option(LDAP_OPT_NETWORK_TIMEOUT,10) nslcd: [7b23c6] DEBUG: ldap_set_option(LDAP_OPT_REFERRALS,LDAP_OPT_ON) nslcd: [7b23c6] DEBUG: ldap_set_option(LDAP_OPT_RESTART,LDAP_OPT_ON) nslcd: [7b23c6] DEBUG: ldap_simple_bind_s("uid=ubuntu,ou=Applications,ou=CITIUS,dc=inv,dc=usc,dc=es","*****") (uri="ldap://172.16.54.31/") nslcd: [7b23c6] connected to LDAP server ldap://172.16.54.31/ nslcd: [7b23c6] DEBUG: ldap_initialize(ldap://172.16.54.31/) nslcd: [7b23c6] DEBUG: ldap_set_rebind_proc() nslcd: [7b23c6] DEBUG: ldap_set_option(LDAP_OPT_PROTOCOL_VERSION,3) nslcd: [7b23c6] DEBUG: ldap_set_option(LDAP_OPT_DEREF,0) nslcd: [7b23c6] DEBUG: ldap_set_option(LDAP_OPT_TIMELIMIT,10) nslcd: [7b23c6] DEBUG: ldap_set_option(LDAP_OPT_TIMEOUT,10) nslcd: [7b23c6] DEBUG: ldap_set_option(LDAP_OPT_NETWORK_TIMEOUT,10) nslcd: [7b23c6] DEBUG: ldap_set_option(LDAP_OPT_REFERRALS,LDAP_OPT_ON) nslcd: [7b23c6] DEBUG: ldap_set_option(LDAP_OPT_RESTART,LDAP_OPT_ON) nslcd: [7b23c6] DEBUG: ldap_simple_bind_s("uid=jorge.suarez,ou=People,ou=CITIUS,dc=inv,dc=usc,dc=es","*****") (uri="ldap://172.16.54.31/") nslcd: [7b23c6] connected to LDAP server ldap://172.16.54.31/ nslcd: [7b23c6] DEBUG: myldap_search(base="uid=jorge.suarez,ou=People,ou=CITIUS,dc=inv,dc=usc,dc=es", filter="(objectClass=posixAccount)") nslcd: [7b23c6] DEBUG: ldap_unbind() nslcd: [3c9869] DEBUG: connection from pid=15906 uid=0 gid=2000 nslcd: [3c9869] DEBUG: nslcd_pam_sess_o("jorge.suarez","uid=jorge.suarez,ou=People,ou=CITIUS,dc=inv,dc=usc,dc=es","su","/dev/pts/7","","jorge.suarez") It seems to me that it won't even try to look for groups.

  • Filesystem access through web interface

    - by Jorge Suárez de Lis
    I have an SSH+Samba server so people can access its files from anywhere on the network. I thought it would be also interesting to provide access through a web interface, so they can access the files even when they don't have access to the VPN or a Samba/SSH client. Something like the Ubuntu One or Dropbox web interface. The http server could be on the same machine as the SSH+Samba, so it should just provide access to local files and some way to login with their username/password. Someone knows any software like this?

  • Connect to virtual host computer from within virtualbox

    - by Nicky De Maeyer
    I'm currently developing on an ubuntu karmic. For this I've installed lampp with a virtual host on apache so http://myproject/ is mapped to my project's root directory. Now to test the website in IE I've installed an XP machine on a virtualBox OSE. Ive managed to get the virtual host working on the XP by adding its to the hostfile, like this: 255.255.255.255 myproject where 255.255.255.255 is the ip adress of the host computer (my ubuntu). Now every day when I come to work and plug in my computer to the network, my IP has changed. so When i boot the XP I have to change the IP in the hostfile to my new IP. Is there any way where I can set the ip to somthing the XP will recognise as the host machine? I've tried replacing the IP in the hostfile by the host computer name, but that does not seem to work... This would make my like a bit easier :)
