• What does the -P option do to mount?

  - by Simon

  I'm migrating from an archaic version of Red Hat to Ubuntu 9. When going through my old nfs mount script, I found that it contained the -P option. So my script looks like: sudo mount -t nfs -o -P ... It looks like the -P is one of the -o options. My question is: what does the -P option do? I've searched every man page I can find, with no luck. Could it have to do with privileged ports?

• Using themes in visio

  - by JohnW

  I'm looking for a good reference on how to properly use themes in Visio. Here's been my experience so far: Create a flowchart diagram - nothing fancy, just all black & white. No formatting applied to any object. Select & apply a theme to the diagram. Despite the theme showing a set of matching colors, the diagram now has a single color applied to all objects. Right-click the object, format, fill, and pick a color from the set of matching theme colors. End up with an amalgamation of the original theme color I picked (blue) and the new color (green). With enough 'playing' with the object, I can get it to look OK, but it feels like I'm missing something, that it shouldn't be this hard to get a matching color. Any advice would be appreciated. :)

• VMware vSwitches and Dell PowerConnect BPDU guard

  - by dunxd

  I am using two Dell PowerConnect 6248 switches to connect a VMware host vSwitch. A discussion of config of Cisco switches for use with VMware advises to set physical ports connected to vSwitch with bpduguard and portfast. However, Dell switches don't have the bpduguard setting for individual ports. I can switch it off globally for all portfast ports, but I don't think I want to do that. Should I: Disable STP on the vSwitch connected ports? Leave STP on and enable portfast on the ports, and forget about bpduguard? Disable bpduguard on all portfast ports via global config Do something else? See also: VMware vSwitches and spanning tree

• Can I easily use a VPN to duplicate SSH Tunneling functionality?

  - by Steve V.

  Right now, when I want to use an unsecured wireless connection with my (Linux) laptop, I secure my connection using a variation of the method provided here. However, to the best of my knowledge, the (non-jailbroken) iPad does not allow applications to tunnel traffic through local ports. However, it does seem to allow certain VPN traffic. I have never set up, or even used, a VPN before. I'm looking for confirmation that I'm not barking up the wrong tree before I invest significant effort into setting up my own VPN server. If I want to secure my wireless iPad traffic over an unsecure wireless connection, would I be on the right track by looking at a VPN?

• XP Mode in Windows 7 professional recently ceased to work

  - by Ian FLetcher

  I have used Windows XP Mode in Windows Professional 7 once a week for around 2 years to run Quicken 98. About 2 weeks ago the XP Mode completely stopped working. I get different responses when I try to launch. I can sometimes see a launch screen for XP (which I never used to get) which then hangs Sometimes I just get a black screen Sometimes I get an error message in a cmd like interface that says "windows could not start because the following file is missing or corrupt \system32\ntoskrnl.exe please reinstall a copy of the above file. I have noticed that in the tools tab at the top of the screen "enable integration features" is greyed out. Any recommendations? Ian

• CentOS default never fsck root partition on start up?

  - by wwwpanda

  Most documentation or sites will say use "tune2fs -l " to check if the system will do fsck on the system partitions on next boot, in particular, should look at "Mount count" and "Maximum mount count" values. However, I notice for default CentOS 5 or 6 installation, when I check against the root partition, I always noticed something like this from tune2fs output: ... Mount count: 91 Maximum mount count: -1 Last checked: Thu Oct 29 18:48:14 2009 Check interval: 0 (<none>) ... i.e. the max. mount count is set to "-1". That makes me wonder does it mean CentOS (or Red Hat) won't check the root partition at all? I check the fstab, the last number for root partition is still "1" as usual. If the OS does fsck the root partition during startup, how can I tell when (i.e. after how many reboots or when) will the OS will start fsck the root parition during startup?

• How does "Compatability Mode" in Windows 7 affect the application?

  - by Robert C. Cartaino

  Background: Based on the answer given to this question: "Skype behaviour in the Windows 7 Superbar" ...you can get Skype to minimize to the system tray (rather than the task bar) by running it in compatibility mode. (red flags going off in my head) That's the behavior that I want but what does "compatibility mode" do to the executing application? I am concerned about changing the execution mode of an entire (important) application to a previous generation just to alter the user interface behavior a bit. So, what does compatibility mode actually do internally? What are the disadvantages, as in "how could the application (Skype) suffer?"

• Is this a graphics card failure?

  - by Alexander Lozada

  I own an older 32-bit Dell XPS 410 that I intended to use for gaming. Currently, I have a ATI Radeon 4000 series card installed, along with a Core 2 Duo and Ubuntu 12.10. I'm fairly certain that my problem is a GPU failure - but before I spend money on a new one, I want to make sure other components aren't the problem/if it would be cheaper just to buy a new PC. Here are my symptoms: Computer power button remains orange (usually green when successfully started.) A fan gets increasingly faster until powered off. Monitor remains black when started, receiving no signal. When powered on, the computer will power itself off near instantly, and then turn on again. If startup is successful, sometimes the screen will become jittered and unusable unless restarted. Is this just a GPU failure, or something more extensive like the motherboard?

• Ubuntu 14.04 disk utility SMART self-test failed threshold not exceeded

  - by user2323470

  I'm using the "Disks" program in Ubuntu 14.04 (live DVD) to assess the health of a drive I suspect is failing. However, when I first opened the program, it showed that the overall health was OK and all assessments are OK as well. I then tried to run a short self-test, but now the overall assessment shows a red "SELF-TEST FAILED". In the details section it says "Last self-test failed (read)" and "threshold not exceeded". All individual assessments are still OK though!! What I don't understand is, does that mean that the test executed and determined that the drive is a goner, or does it mean that the test didn't actually execute properly?

• How do I enable SELinux when booting a ramdisk from a CD/DVD?

  - by JeffG

  I have a bootable DVD which boots the same Kernel as the Hard Drive (which uses SELinux). I have copied /etc/selinux and all kernel modules to my ramdisk, and have tried various combinations of selinux=1 and selinux 1 with enforcing 1 and enforcing 0. as Kernel boot parameters. All files contained in the checkpolicy, libselinux, policycoreutils, selinux-policy and selinux-policy-targeted rpms have also been copied into the ramdisk tree. After the system boots from the ramdisk, I check dmesg: % dmesg | grep -i selinux Kernel command line: initrd=idrd.img ramdisk_size=110476 selinux=1 SELinux: Initializing. SELinux: Starting in permissive mode selinux_register_security: Registering secondary module capability SElinux: Registering netfilter hooks But SELinux isn't running: % /usr/sbin/getenforce Disabled % /usr/sbin/setenforce 1 /usr/sbin/setenforce: SELinux is disabled Neither /var/log/messages nor /proc/kmsg hold clues.

• Virtual Box fails my OSes :(

  - by Kingston Town

  I have a little problem with Virtual Box latest version in which i have installed Mint (also latest version).During creation of a new vdi partition I chose settings as default, that is, I don't create any tiny partitions myself. The installation works. But later while the new OS is running (not in Live mode) I try installing/updating new software available, the system automatically fails, it reports an error of DISKFULL, I close the message box then power off my system. Later on I can't boot it up again anymore. It hangs with a black screen and the PAUSE status. I have no idea why. I have installed 2 OSes and both fail at the same error. I doubt something is not right about the current version of VBox. Thank you . My host OS is Windows7 and my Clients are Mint and CentOS

• Ultra Low Latency Linux Distribution or Kernel

  - by Zanlor

  I'd like to know if there are any linux distributions that are focused on low latency networking. The area I'm working in is algorithmic trading, and extremely low latency comms between machines is a must. The current h/w we're using is 10g ethernet, we're looking into things like infiniband RDMA and Voltaire VMA I've googled around, and have only been able to find tidbtits of kernel patches, command line options and hardware suggestions. I'm looking for a complete solution, specially built kernel, kernel bypass features, essentially all the goodies rolled up into one package - does such a thing even exist? I ask as a lot of this stuff seems to be a black art, people keep secret what they know works etc.

• Not able to access a folder in Windows 7 and not able to see in Ubuntu.

  - by Rohit

  I have four partitions on my hard disk. Partition C has Windows XP installed and Partition G has Windows 7 installed. Ubuntu 10.10 is also installed, probably in F. Partitions C and G are NTFS. When I boot into C, XP is loading but when I click on the C Drive in MyComputer, it displays: "Access is denied". Windows 7 displays the folder tree of C, but when I try to open a folder, I am not able to view the contents. The same error: of Access Denied. When I try to view the C Partition using Ubuntu, the entire C partition is not visible. I tried following commands to take ownership of the C drive: takeown /f C: cacls C: /G Rohit:F but still I am not able to get rid of "Access Denied". I again tried the above commands from the Windows 7 safe mode, but still the problem persists. The two commands return "Successful", but nothing is happening.

• Windows 7 boot problem on a Lenovo Thinkpad Z61m 9450HAG

  - by Matt Taylor

  Hello, I recently did a full upgrade of windows 7 on my thinkpad, everything worked fine after up until the second reboot (the first reboot after some updates installed worked OK). At second reboot time the system would just black screen just before the Windows logo appears, disk/wireless/power/battery lights are all lit and the disk light is active (flickering). However, if I remove my battery and boot with just power it boots fine and quickly, and everything is OK. Any help on why this wont boot with battery plugged in is greatly appreciated - i need to take this battery out on the road/trains etc.... Cheers Matt

• Operation System Clone from a Motherboard to Another

  - by Devian

  Lately we had an idea with my Family of building a Super Computer from Scratch. So while we were planning on building our setup, one idea came to my head that it seems possible but i want also your opinions. Lets say that we have 2 ATX Motherboards and 1 MicroATX. Motherboard Setup: 1x ASUS Rampage Extreme Black Edition 1x Intel Core i7 4960x 4x GTX Titan 8x 8GB 1866 Ram Motherboard Setup: 1x SuperMicro X9DRG-QF 2x Intel Xeon E7-8890V2 1x nVIDIA QUADRO K6000 4x nVIDIA Tesla K40 128 GB 1866 Ram And imagine a Solid State Drive with a Switch connected to both of the MotherBoards Can i edit & copy all the data of The first motherboard's RAM to The Other's to be able to continue operating my current Operation System after switching the SSD to the Second Motherboard, from the Second MotherBoard and vice versa? Les say my "Switch Application" modifies everything the Kernel needs to believe nothing happend and continuing its operation from the same point the first motherboard stopped. (Changes on the Device List, CPU Cores, Drivers... etc)

• Open source command line tools for indexing a large number of text files

  - by ergosys

  I'm looking for any open source command line tool or tools which will allow me to index and search a large number of plain text files. Approximate search would be a plus. The tool only needs to print the files that match, although some match context would be useful. A GUI tool isn't useful for my application, nor is anything that searches files one by one (grep for example). I'm basically targeting unix platforms (osx, linux, bsd). EDIT: I'm not interested in any sort of tool that is system-wide, or needs to run in the background. Basically, I want to build an index for a directory tree full of text files and then later be able to search against it. Preferably the index is one or a few files that I can specify the location of. Any ideas?

• Project management software that syncs with smartphone?

  - by overtherainbow

  Hello, I went through the archives here and the Wikipedia page on Project management software, but didn't find information on this type of application to manage projects: Native Windows application (don't like web-based solutions; prefer native to cross-platform) Free or affordable, ie. not an Enterprise solution Scalable from one to a few concurrent users Like MS Projet et al., a project consists in tasks which can be further divided into sub-tasks, and the whole thing is displayed in an tree list An item that has a date set (either start/due) must be displayed in a Calendar view, so it's easy to know what work must be done each day The Calendar view must somehow sync with smartphones (at least BlackBerry) At this point, the apps I know either don't provide a Calendar at all, or do but they can't sync with smartphones, which forces me to copy/paste scheduled items into Outlook so they are synced with my BlackBerry :-/ Thank you for any help.

• How to disable Microsoft eHome MCIR Keyboard and company?

  - by AndrejaKo

  Hi! I'm and unlucky owner of and Acer 7720G laptop which, like many in its category, has receiver for a proprietary infra red remote control device (which I did not receive with my laptop!) . Now my problem is that the receiver is detected as Microsoft eHome MCIR Keyboard, Microsoft eHome MCIR 109 Keyboard and Microsoft eHome Remote Control Keyboard keys. My problem is that this driver has incompatibilities with some programs I use like for example DosBox. When these devices are installed, they cause DosBox to incorrectly detect some keyboard buttons. The workaround is to remove or disable the 3 hardware devices. Unfortunately, I the disable option is grayed out and when I delete them, they are reinstalled on next restart. Is there any way to hack windows in order to prevent their installation? I was thinking about locating the drivers these devices use, but they are buried somewhere in windows installation and I don't have enough experience to find them, so I'm asking you for help.

• Map /dev/bus/usb node to /sys node on Linux

  - by Cody Brocious

  I'm using libusb to find and access a USB device, but once I get the information I need from there, I need to map it to a /sys node. This could be to the actual USB bus it's on, the /sys/bus/usb-serial node (which is where I'm going to get eventually), or effectively anywhere else since I can walk the tree from there. I can get to a /dev/bus/usb node easily enough, but I'm a bit lost from there. What would be the best route to perform this mapping? Alternatively, a way to get the /dev/ttyUSB device node for a /dev/bus/usb node would work as well, since it gets me the same result.

• How to get Windows 7 logon wallpaper to tile to other monitors?

  - by Oskar Duveborn

  In 2000/XP/Vista it was easy to set a wallpaper for the logon screen, either manually through tools like Logonstudio or simple registry changes by hand on prepared installation images or through custom group policies. In Windows 7 all this works as usual, but the secondary (or any additional) monitor is just black. The mouse pointer is visible on it but no matter what settings I can't get the wallpaper to tile (or stretch or fill or whatever) over onto it. This makes it hard to OEM/company brand the installation for multi-monitor users. More annoying is the fact that it looks officially supported to brand the logon wallpaper in Windows 7 - as it's made extremely easy... apart from this little catch.
