    A remote machine running fedora uses openvpn, and multiple developers were successfully able to connect to it via their client openvpn. However, I am running Ubuntu 12.04 and I am having trouble connecting to the server via vpn. I copied ca.crt, home.key, and home.crt from the server to my local machine to /etc/openvpn folder. My client.conf file looks like this: ############################################## # Sample client-side OpenVPN 2.0 config file # # for connecting to multi-client server. # # # # This configuration can be used by multiple # # clients, however each client should have # # its own cert and key files. # # # # On Windows, you might want to rename this # # file so it has a .ovpn extension # ############################################## # Specify that we are a client and that we # will be pulling certain config file directives # from the server. client # Use the same setting as you are using on # the server. # On most systems, the VPN will not function # unless you partially or fully disable # the firewall for the TUN/TAP interface. ;dev tap dev tun # Windows needs the TAP-Win32 adapter name # from the Network Connections panel # if you have more than one.

  • Hot to fix nautilus desktop on linux mint

    - by user59530
    so I'm using Linux Mint 13 with Cinnamon and suddenly there are no icons on the desktop and the right click doesn't work, it's like the desktop doesn't start up at all, but the Cinnamon interface and everything else are working just fine. This happens only when I open the session with Cinnamon, if I start the session on the classic Gnome or MATE the desktop works. I tried to re-install Cinnamon but nothing changed. Then, I noticed that there are some little problems in Nautilus (sometimes menus aren't the color they're supposed to be), so I'm convinced that Nautilus might be the problem, but I don't know how to fix this, I've tried a few thing but I'm starting to fear that I'm only making it worse. Also, when I open the terminal and type in nautilus here's what's shows up, any help? (nautilus:2906): Gtk-WARNING **: Theme parsing error: gtk-widgets.css:85:17: Not using units is deprecated.

  • Problem using Polar Irda device in Windows Server 2008

    - by AngrySpade
    I'm attempting to use the Polar IrDA device with Windows Server 2008 R2 x64. Although they dont make explicit drivers for it, I figured the Windows 7 x64 drivers would do. http://www.polar.fi/en/support/downloads?product=&category=Software&documenttitle=Polar+IrDA+USB+Adapter+drivers&document=/gip/PKBStoGIP.nsf/web_cat/C225742500419A8AC2257458003D3F40 The device has a yellow warning icon in Device Manager. Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19) Is there anything I can do about this?

  • Sony VAIO TZ2 internal camera and Windows XP

    - by user34300
    I have a Sony Vaio TZ2 laptop here and I'm trying to install Windows XP SP3 on it. Everything works fine except of the integrated camera which is supposed to be a USB device but is absent in the Devoice Manager. I've read that it is important in what order you install drivers when you downgrade this Vista preinstalled model to Windows XP so I repeated once again the installation with the correct order by still had no luck with the camera. Can someone give me an advice on how to woke up this camera? Thanks!

  • Queries related to Windows 8 Upgrade installation media

    - by Karan
    I don't expect all these questions to be answered right away. Gradually over time is fine. Also, I guess the answers would differ depending on the language, so I'm looking for information related to the English/en-US versions only (I believe there is an en-GB version as well?) The Windows 8 Upgrade Assistant allows one to create USB/DVD (ISO) media: Is the media customised per-PC in any way, or are copies created on different PCs with different base OSes (XP/Vista/7) exactly the same? If the ISOs are not customised, are they exactly the same content-wise as the Upgrade DVDs available for purchase?

  • ubuntu automount: only mounting drives as root?

    - by glisignoli
    I'm sharing the /mount dir with smb so users on my network can access use drives added to my linux box. Users are able to read files but not write, modify or delete files or directories. I'm using ubuntu 10.04 server edition with halevt installed for usb auto mounting. Afaik halevt is automounting the drives to /media/ but the drives are showing up as: drwxrwxr-x 1 root root 20480 2010-12-29 20:40 disk drwxrwxr-x 1 root root 24576 2010-12-21 17:20 Sparta mount gives me: /dev/sda1 on /boot type ext2 (rw) /dev/sdb1 on /media/disk type fuseblk (rw,nosuid,nodev,sync,allow_other,blksize=4096,default_permissions) /dev/sdc1 on /media/Sparta type fuseblk (rw,nosuid,nodev,sync,allow_other,blksize=4096,default_permissions) When I umount the drives, the folders /media/disk and /media/Sparta are both removed. I tried changing the permissions with chown to nobody:nogroup but it doesn't work (which I assume is because they are ntfs drives).

  • No device file for partition on logical volume (Linux LVM)

    - by Brian
    I created a logical volume (scandata) containing a single ext3 partition. It is the only logical volume in its volume group (case4t). Said volume group is comprised by 3 physical volumes, which are three primary partitions on a single block device (/dev/sdb). When I created it, I could mount the partition via the block device /dev/mapper/case4t-scandatap1. Since last reboot the aforementioned block device file has disappeared. It may be of note -- I'm not sure -- that my superior (a college professor) had prompted this reboot by running sudo chmod -R [his name] /usr/bin, which obliterated all suid in its path, preventing the both of us from sudo-ing. That issue has been (temporarily) rectified via this operation. Now I'll cut the chatter and get started with the terminal dumps: $ sudo pvs; sudo vgs; sudo lvs Logging initialised at Sat Jan 8 11:42:34 2011 Set umask to 0077 Scanning for physical volume names PV VG Fmt Attr PSize PFree /dev/sdb1 case4t lvm2 a- 819.32G 0 /dev/sdb2 case4t lvm2 a- 866.40G 0 /dev/sdb3 case4t lvm2 a- 47.09G 0 Wiping internal VG cache Logging initialised at Sat Jan 8 11:42:34 2011 Set umask to 0077 Finding all volume groups Finding volume group "case4t" VG #PV #LV #SN Attr VSize VFree case4t 3 1 0 wz--n- 1.69T 0 Wiping internal VG cache Logging initialised at Sat Jan 8 11:42:34 2011 Set umask to 0077 Finding all logical volumes LV VG Attr LSize Origin Snap% Move Log Copy% Convert scandata case4t -wi-a- 1.69T Wiping internal VG cache $ sudo vgchange -a y Logging initialised at Sat Jan 8 11:43:14 2011 Set umask to 0077 Finding all volume groups Finding volume group "case4t" 1 logical volume(s) in volume group "case4t" already active 1 existing logical volume(s) in volume group "case4t" monitored Found volume group "case4t" Activated logical volumes in volume group "case4t" 1 logical volume(s) in volume group "case4t" now active Wiping internal VG cache $ ls /dev | grep case4t case4t $ ls /dev/mapper case4t-scandata control $ sudo fdisk -l /dev/case4t/scandata Disk /dev/case4t/scandata: 1860.5 GB, 1860584865792 bytes 255 heads, 63 sectors/track, 226203 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00049bf5 Device Boot Start End Blocks Id System /dev/case4t/scandata1 1 226203 1816975566 83 Linux $ sudo parted /dev/case4t/scandata print Model: Linux device-mapper (linear) (dm) Disk /dev/mapper/case4t-scandata: 1861GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 32.3kB 1861GB 1861GB primary ext3 $ sudo fdisk -l /dev/sdb Disk /dev/sdb: 1860.5 GB, 1860593254400 bytes 255 heads, 63 sectors/track, 226204 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00000081 Device Boot Start End Blocks Id System /dev/sdb1 1 106955 859116006 83 Linux /dev/sdb2 113103 226204 908491815 83 Linux /dev/sdb3 106956 113102 49375777+ 83 Linux Partition table entries are not in disk order $ sudo parted /dev/sdb print Model: DELL PERC 6/i (scsi) Disk /dev/sdb: 1861GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 32.3kB 880GB 880GB primary reiserfs 3 880GB 930GB 50.6GB primary 2 930GB 1861GB 930GB primary I find it a bit strange that partition one above is said to be reiserfs, or if it matters -- it was previously reiserfs, but LVM recognizes it as a PV. To reiterate, neither /dev/mapper/case4t-scandatap1 (which I had used previously) nor /dev/case4t/scandata1 (as printed by fdisk) exists. And /dev/case4t/scandata (no partition number) cannot be mounted: $sudo mount -t ext3 /dev/case4t/scandata /mnt/new mount: wrong fs type, bad option, bad superblock on /dev/mapper/case4t-scandata, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so All I get on syslog is: [170059.538137] VFS: Can't find ext3 filesystem on dev dm-0. Thanks in advance for any help you can offer, Brian P.S. I am on Ubuntu GNU/Linux 2.6.28-11-server (Jaunty) (out of date, I know -- that's on the laundry list).

  • How to determine if a device is SATA driven and will be affect by the Sandy Bridge Intel Issue?

    - by joelhaus
    Looking to buy a higher-end Windows 7 laptop, but I'm concerned about the issue with the Intel Sandy Bridge chipset. Otherwise, my price range covers laptops within the latest (Sandy Bridge) generation of the Core i7 family. I understand that there is an issue with SATA ports 2-5 and I use a Windows Home Server over a WiFi connection to share files and backup my PC. The other storage devices that I will use (less frequently) are the built-in DVD-RW disc drive and various devices hooked up to the USB ports (i.e. Android devices, iPod, etc.). The question: Will this setup be negatively impacted by the problem Intel reported about Sandy Bridge? Given this information, is it unwise to purchase a laptop that has this flaw? I really don't know how to determine whether a device is SATA driven or not, so hoping someone can shed some light on this too. Thanks!

  • Is an Ethernet point to point connection without a switch real time capable?

    - by funksoulbrother
    In automation and control, it is commonly stated that ethernet can't be used as a bus because it is not real time capable due to packet collisions. If important control packets collide, they often can't keep the hard real time conditions needed for control. But what if I have a single point to point connection with Ethernet, no switch in between? To be more precise, I have an FPGA board with a giga-Ethernet port that is connected directly to my control PC. I think the benefits of giga Ethernet over CAN or USB for a p2p connection are huge, especially for high sampling rates and lots of data generation on the FPGA board. Am I correct that with a point to point connection there can't be any packet collisions and therefore a real time environment is given even with ethernet? Thanks in advance! ~fsb

  • External Hardrive Not Reconized on Windows 7 at all

    - by Bella
    I Have a NextStar 2/5" from Vantec and its an 80G HD. I have used it many times on windows xp and it works fine. We just recently upgraded to windows 7 home premium and when I plug it in it beeps many times. I've tried all the USB plugs in my computer and its not those plugs. Haven't tried eSata because it uses a weird cable to plug into. People told me that when it beeps everything is corrupted, but works fine on xp. I tried installing the drivers online from their website and when I try it asks me to put in a cd which makes no sense because they are online drivers. When I go into device manager nothing comes up, it just acts like the HD is invisible. The beeping will stop eventually as it is plugged in, but with no result.

  • Enabling the log app on the WDTV

    - by Ariel Popovsky
    Just flashed the last WDXLTV firmware on my WDTV and it's working fine. I tried to config a Wifi USB adapter but couldn't get it to work. Dropped the log-saver.app.bin on the root of the stick but didn't find any log files after booting. What I'm doing is turning on the WDTV with the stick inserted (the stick is formatted with FAT32). Tried with the wireless-mod.app.bin required files and without any other file than the log saver. I can't get a log file anyway. All I want right now is to get the log file so I can debug the WI FI adapter.

  • Wireless Keyboard Intermittent Failure to Type and Added Characters

    - by Kashif
    My keyboard has been acting up from time to time. It's wireless so this may be a wireless issue. What happens is I will be typing and then all of a sudden it seems to stop responding. If I type out this sentence it may show up like so If I ttennnnnnnnn it may ssssssp so While typing that sentence I may have to mash on a key repeatedly to get it to type. The resulting strings of letters seem to be coming as if the keyboard buffer cannot keep up. It's so weird. If I take the USB tranceiver and yank it out then plug it back in, Voila! Problem solved. I did the battery check so that's not a problem. Any suggestions? My keyboard is the Logitech MX3200

  • "Windows was unable to complete the format" - Can't format flashdrive!!!

    - by Jake
    I have a 8GB Sandisk Cruzer USB flash drive that I had ruined a while back trying to make it bootable. Anyway now when I click on it I get a message that it needs to be reformatted to be used. So when I try to do that, the formatting starts and suddenly ends with the message "Windows was unable to complete the format". This happens no matter which file system I choose (NTFS, FAT32, exFat) and also which computer I try this on. I am now on a Windows 7 32 bit OS and before tries it on a Vista Home Basic machine. Anyone know any way around this issue? Many thanks.

  • Why does my computer slow down so much when attaching Bluetooth dongle?

    - by Jeff Yates
    I have a Bluetooth dongle and I plugged it into my work laptop (a Dell Latitude D830). Windows detects the Generic Bluetooth USB or similar and then proceeds to go incredibly slow with a process, avp.exe¹, taking 50% CPU. The System Idle process is getting most of the other 50% CPU and the avp.exe process is only at Normal priority. The machine doesn't seem to recover, so I had to turn the power off and reboot. Now, I haven't installed the drivers yet for the device, which I am doing now and I expect it to resolve the problem, so I am not asking how to fix this. I would rather know why Windows goes so slow in the first place. What is it trying to do and failing at so badly that it barely crawls? ¹ Part of Kaspersky Internet Security suite

  • HP ProLiant DL320e G8 v2 - USB2.0 during POST

    - by user3513346
    Initially my USB2.0 ports were working during POST (and boot). However, now they appear not to be. I first noticed this when I could not access the RBSU by pressing F9 during POST. Then found that I couldn't boot from USB either (I was able to do both of these initially). When performing the boot via iLo remote console I can access all of the setups (i.e., all of the F(X)'s) and can boot virtual media from a 'removable drive'. Keyboard works fine once the OS is booted. Not really sure what to try here. Any advice would be greatly appreciated. Thanks. Nick.

  • In what way does non-"full n-key rollover" hinder fast typists?

    - by Michael Kjörling
    Wikipedia claims (although the latter claim does not cite a source) that: High-end keyboards that provide full n-key rollover typically do so via a PS/2 interface as the USB mode most often used by operating systems has a maximum of only six keys plus modifiers that can be pressed at the same time.[4] This hinders fast typists, ... In what way would the system being able to recognize only six non-modifier keys at once hinder a fast typist? I consider myself a relatively fast typist and I usually press one key, plus modifiers, at once; I can't imagine any real-life situation in which the system only recognizing six non-modifier keys being pressed at once has been a limiting factor in my keyboard usage. (Multi-stroke keyboard shortcuts as used by high-end software like Visual Studio, Emacs and the like are a different matter.) Note that I am not really interested in answers centered around multiplayer computer games; I'm looking for answers that give reasons that would be relevant to typists, somehow supporting the statement made on Wikipedia.

  • Making backup of the System Restore Partition with netbooks

    - by devoured elysium
    I have a netbook that has two partitions. A first one where I have all my programs and stuff and a second one that came with the netbook and has the data so I can restore my computer if I need to. Now, as I had problems in the past with other computers that had a similar restore scheme, I know I must in some way do a backup of this partition, so if there is any problem I can put everything working again. How should I proceed? As this is a netbook, it doesn't have a CD reader. Maybe doing a backup of this partition to a 12GB(it seems this partition occupies this much!) usb? How could I do it? Thanks

  • Logitech M185 Wirless Mouse issue

    - by Elliot Harrison
    An issue with a Logitech M185 mouse today. A user is unable to use the device. The device works perfectly fine on my PC (It appears as HID-compliant mouse), but not on her laptop. It does not appear in her device manager on the 'Mice and other pointing devices' section. I did notice an unknown device in the Universal Serial Bus Controllers section, but when I try to update the driver, it says it has the most up to date driver. We've tried plugging in the dongle in multiple USB slots but no luck. Any advice? It's a HP 620 Laptop on Windows 7. Thank you :)

  • Just bought Logitech G35 headset, want to enable/disable headet in one action

    - by Roy Rico
    Hello, Just bought Logitech G35 USB headset, want to enable/disable headet in one action. I have windows 7 64 bit, and currently, to switch from the headset to my spakers (or vice versa) without unplugging the headset, i have to go thru this steps: right click on the sound icon select "sounds" select the "Playback" tab right click headset and hit enable right click speakers and hit disable same steps when wanting to switch back I have to disable the devices, because not all of the programs which are outputting sound will switch immediately if I just set either device to default. I am looking for this to be a single action (either a batch script or a windows shortcut to some action with parameters?) Thanks!

  • CentOS - Add additional hard drive raid arrays on Dell Perc 5/i card

    - by Quanano
    We have a Dell Poweredge 2900 system with Dell Perc 5/i card and 4 SAS hard drives attached, with NTFS partitions on them. We installed CentOS on one raid array on this controller with a different controller and it is working fine. We are now trying to access the drives shown above and they are not being shown in /dev as sdb, etc. sda is the drive that we installed centos on and it has sda1, sda2, sda3, etc. The CDROM has been picked up as well. If I scan for scsi devices then the perc and adaptec controllers are both found. sg0 is the CDROM and sg2 is the centos installed, however I think sg1 is the other drive but I cannot see anyway to mount the partitions, as only the drive is listed in /dev.

  • Windows Phone 8 not interfacing with Zune software

    - by Cyberherbalist
    I just got a Lumia 521 with Windows Phone 8 and am trying to get the device to work with the Zune software on my PC. I still have my Windows Phone 7 device, and the new one is not working the same way. When I plug the WP7 device into the PC's USB port, it automatically fires up Zune and I can sync my podcasts and music etc to the device. But when I plug the Lumia into the PC it doesn't fire up Zune, and if I start Zune manually, it doesn't interface with the phone at all. Perhaps I am missing something and WP8 isn't supposed to use Zune to interface with the phone?
