  • What does the - option to env do?

    - by grifaton
    From the man page for env: The historic - option has been deprecated but is still supported in this implementation. What does the "historic - option" do? In particular, why does it change which version of python is run? ~:$ env python Python 2.6.5 Stackless 3.1b3 060516 (release26-maint, Mar 24 2010, 09:47:07) but: ~:$ env - python Python 2.5.1 (r251:54863, Feb 6 2009, 19:02:12)

  • Shinken - Anyone using it?

    - by Marco Ramos
    I've recently discovered Shinken, which a new implementation of Nagios using python. Shinken "divides" Nagios in 5 different types of agents, each one performing separated tasks. I haven't tried it yet but for what I've seen the whole architecture idea seems great to me (it works the Unix way: one process, one task), but the project seems a little "green" yet. So, has anyone tried Shinken? What's your opinion?

  • How can we use Microsoft Groove with peers existing in both secure and unsecured network segments?

    - by MikeHerrera
    We have been instructed to implement a Microsoft Groove workspace. This would normally not be a concern, but the workspace will be utilized by machines which exist in our internal/restricted network as well as from peers from an outside/unknown network. Does there exist a best-practice for such an implementation?... or would this potentially expose the restricted network too broadly?

  • X.org - mouse gets stuck on press

    - by grawity
    I'm using Arch Linux. Very often, when I click on something, the OS thing sees the mouse press but not the release. If it was a link or file I clicked, moving the cursor would drag it too. Hammering the same mouse button again gives no effect. Usually, if I tap the touchpad (ALPS), the system finally sees both press and release of that, and I can continue working. (This might be because it uses a different driver - synaptics instead of evdev.) As you can imagine, this is quite annoying even for someone who spends 70% of his life in front of a terminal app. This is not a mouse issue - I'm on a laptop, and this affects both the Trackpoint thing and an external USB mouse. This is not a DE or window manager issue - I have used GNOME (with Metacity, Compiz and Xfwm4), Xfce (with Metacity and Xfwm4), mwm, twm, awesome, and wmii. Doesn't seem to be a hardware thing - after rebooting into Windows XP, everything works fine. hal is used for the auto-configuration of devices (as I have to disconnect the USB mouse often), so Xorg.conf really has nothing of relevance. Xorg -version shows: X.Org X Server 1.6.3.901 (1.6.4 RC 1) Release Date: 2009-8-25 X Protocol Version 11, Revision 0 If it changes anything, the laptop is stone-age Dell Latitude C840. I kinda suspect either hal or the evdev thing to cause it, but I really have no ideas on what to check further. In other words, HALP!#$ This thing is driving me nuts.

  • Windows 7 x64 wired connection problem. IP, gateway, dns assigned, can't ping. Network detected as "Network"

    - by Emil Lerch
    I am having a problem connecting to a specific wired network with my Latitude E6410 laptop. Other wired networks seem to work fine, but this one does not. I have a coworker with me with the same Intel 82577LM Gigabit Network card, and he can connect just fine. I've updated to the latest Intel drivers (11.8.75.0) and am not using Pro Set. I obtain all DHCP information just fine (IP, netmask, DNS server, default gateway). I cannot ping anything (internal or on the Internet - I tried pinging Google's public DNS servers by IP 8.8.8.8), nor can I get answers to any DNS queries through NS Lookup. Windows troubleshooting says everything is fine, but I can't get DNS responses. I've seen issues like this in the past that were related to link speed/duplex autonegotiaion failures, so I've tried manually setting link speed/duplex to all values one by one with no success. My coworker is using all default settings, so he is just using autonegotiate. Any ideas of other things to try?

  • Firefox crash on first load on Ubuntu Linux on Windows Laptop

    - by Ira Baxter
    I've had a Dell Latitude laptop since about 2000 without managing to destroy it. A month ago the Windows 2000 system on it did something stupid to its file system and Windows was completely lost. No point in reinstalling Windows 2000, so I installed an Ubuntu Linux on the laptop. Everything seems normal (installed, rebooted, I can log in, run GnuChess, poke about). ... but ... when I attempt to launch Firefox from the top bar menu icon, I get a bunch of disk activity, the whirling cursor icon goes round a bit and then everything stops: disk, icon, mouse. Literally nothing happens for 5 minutes. Ubuntu is dead, as far as I can tell. A reboot, and I can repeat this reliably. So on the face of it, everything works but Firefox. That seems really strange. The only odd thing about this system when Firefox is booting is that while it has an Ethernet port (that worked fine under Windows), it isn't actually plugged into an Ethernet. As this is the first Firefox boot since the Ubuntu install, maybe Firefox mishandles Internet access? Why would that crash Ubuntu? (I need to go try the obvious experiment of plugging it in).

  • How to fix Quicktime video color problems on nVidia chipset and Windows XP?

    - by Matthew Glidden
    My laptop frequently plays video as if in very low-color mode. Though the sound remains clear, it looks terrible, showing only a few shades of red, blue, or yellow. (It's even worse than 8-bit color.) The problem doesn't happen consistently, so I'm looking for troubleshooting advice or known solutions. I use a Dell Latitude D620 laptop with Windows XP, on-board nVidia video chipset, Quicktime, and multiple monitors (laptop screen + VGA-connected LCD). Color problems happen in each application I tried, iTunes, a browser, and the Quicktime standalone player. It doesn't happen right after reboot, so could be from a sleep-wake cycle, or at least being on for an extended period. Google results suggest reinstalling nVidia drivers, which I've done several times with no change. I have found 2 workarounds. Reboot, sacrificing significant time and disrupting work In nVidia control panel, change color to 16-bit, and then back to 32-bit This happens with all video playback, so it's definitely not one corrupt file. I use workaround #2 consistently, but would love a longer-term solution.

  • Saving blog items as pdf's

    - by ldigas
    I know of FireShot, a firefox extension, for saving up whole pages of images. And I love it. Great idea, and a very good implementation. But unfortunatelly, often on this kind of sites, you have links which get lost that way. So I'm wondering, is there a way to save in the same manner whole blog posts, wiki posts, StackOverflow posts :), as PDF files, so the links get saved as well ?

  • ISC DHCP - Force clients to get a new IP address, instead of the being re-issued their previous lease's IP

    - by kce
    We are in the middle of a migration of our DHCP and DNS services from a Debian-based server to a Windows Server 2008 R2 implementation. The Debian server is running isc-dhcpd-V3.1.1. All of workstations are configured to have fixed-addresses between .3 and .40 (the motivation behind that choice is mostly management/political much like here). DHCP leases are given out in the range of .100 to .175. Statically configured servers live in the .200 block and above (which is mostly empty). When we move to the Windows platform, management/political considerations require me to move the IP ranges around again. We would like to keep .1 - .10 reserved for network appliances, switches, and other infrastructure. .200 will remain designated for servers. The addressing space in between should be available to clients and IPs should be dynamically allocated (Edit: instead of automatic as originally mentioned) by the server. My Address Pool on the Windows Server looks like this: 192.168.0.1 192.168.0.254 (Address range for distribution) 192.168.0.1 192.168.0.10 (IP addresses excluded from distribution) 192.168.0.200 192.168.0.254 (IP addresses excluded from distribution) Currently, we have all of our clients still on the .3 - .40 range, and a few machines still active in the .100 - .175 (although there are lots devices that are powered off that still have expired leases with IPs from that range). Since the lease "database" isn't shared between the old and new DHCP server how can I prevent clients from receiving a lease with an IP address that is currently being held by client with a non-expired lease from the old DHCP server? If I just expand the range on the Debian DHCP server to be 192.168.0.10 - 192.168.0.199 is there a way to force clients to not re-use their old IP address when they send their DHCPDISCOVER? Can I make the Windows DHCP server be authoritiative like the ISC implementation? The dhcpd.conf from the Debian server: ddns-update-style none; authoritative; default-lease-time 43200; #12 hours max-lease-time 86400; #24 hours subnet 192.168.0.0 netmask 255.255.255.0 { option routers 192.168.0.1; option subnet-mask 255.255.255.0; option broadcast-address 192.168.0.255; range 192.168.0.100 192.168.0.175; } host workstation-1 { hardware ethernet 00:11:22:33:44:55; fixed-address 192.168.0.3; } ... and so on until 192.168.0.40

  • Window 7 Computer name changing on its own?

    - by DC
    Very odd problem... I have a Dell Latitude D830 with XP Pro that has been running on my local domain for many years. I recently Installed Windows 7 Enterprise on the D830 using a brand new HDD so that I could still use XP if I needed by just swapping out the HDD's. I added the W7 installed system to my domain using a completely different machine name than that used for the XP system and everything seemed to be functioning as it should. On boot up over the last 2 weeks or so I occasionally (3 times now) get to the login screen and try to login to the domain only to get an error saying that the Computer name is not a trusted machine in the domain I'm trying to log in to. Come to find out that the machine name on the W7 system has been changed somehow to that of my old XP system. If on the W7 system I then change the name back to the correct name, disjoin the domain, reboot, add the machine back into the domain … all is well for an unknown period of time until this happens again. This last time, I know for a fact that everything was fine the day before when I shut down the system. I came in today, powered up the system and the machine name had been changed to that of my old XP system again. Has anybody else seen this behavior or hav any ideas on what could be causing it? Thanks!

  • Kernel Memory Leak in Ubuntu 9.10?

    - by kayahr
    After some days of work (Using suspend-to-ram during the night) I notice I loose more and more available memory. Even when I close all applications the situation doesn't improve. I even went down to the command line and closed ALL running processes except the init process and the bash I'm working in. I unmounted all these ram disks which Ubuntu is using, I even unloaded all modules which could be unloaded. But still "free" tells me that 1 GB of RAM is used (without buffers/cache). In "top" there is no visible process which occupies all this memory. The only way to free the memory is restarting the machine. How can I find out where I lose all this memory? Is there a known "suspect" who can cause a problem like this? I'm using Ubuntu 9.10 64 bit on a Dell Latitude E6500 (4 GB RAM) with the latest closed-source nvidia driver and Gnome with Compiz. The applications I use most of the time are firefox and eclipse. Any hints how I can find the problem? I'm not a kernel hacker so if the solution is patching the kernel or something like that then I might be out of the game...

  • Apache LimitExcept not behaving as expected

    - by Farseeker
    I have the following directive in my Apache httpd.conf: <LimitExcept OPTIONS PROPFIND REPORT> deny from all </LimitExcept> OPTIONS and PROPFIND work as expected, but REPORT returns 400: Bad Request. Removing the LimitExcept alltogether and everything works as expected. Any ideas on why this might be? (This is the implementation of my question here).

EDIT: I tried to run the Disk manager tool, not that I cared what it was, just a menu-available application. It started up like Firefox, I get a little tag in the lower left saying Disk P*** something had started, and then the same behavior as Firefox. At this point, I don't think its the Ethernet. Is it possible that the Ubuntu disk driver can't handle the disk controller in this older laptop? The install seemed to go fine.

  • What Is The Proper Laptop Battery Care While Running Laptop Solely On Battery?

    - by Boris_yo
    Because of convenience, I had to move my laptop to another room away from room where I always ran laptop on UPS without using battery. Since so far I always run laptop on battery, I question the proper usage to prolong battery life. Currently I run laptop on battery with power supply so battery is constantly being charged until it is full 100% and when it is, I disconnect power supply and continue working until battery meter shows 10% remaining. That's when I plug in power supply and let it charge until 100% once again while I work. But it takes a lot of time to fully charge laptop while working since my power supply is 60W which should be the reason of such slow charge and I think the kind of charger that I use is express charger. The thought of charging laptop until full, all while doing my work makes me think that if it takes way more time to charge, it might keep battery running warm for the period of charging time which brings me to question about whether I should keep running laptop as I've described above or it would be better to leave power supply constantly connected to laptop to keep battery between 99%-100%? On one hand it won't keep battery warm but it will try to frequently supply charge to battery once it gets 99% to replenish charge to 100% (which might reduce battery life?). On the other hand if I'll keep working solely on battery and recharge it when below 10%, the battery will get warm but only when charged. Can anybody suggest the correct way of running laptop on battery to ensure better battery life? Dell Latitude E6420 Windows 7 64-bit

  • Docking Station Sound Doesn't Work on Dell D830 with Windows 7

    - by cisellis
    I have a Dell Latitude D830 laptop that is running Windows 7 Enterprise x64. I connect to a docking station during the day with multiple monitors, a keyboard and a mouse. Everything runs with no problems including most of the docking station ports (usb, monitors, etc.) However, the sound port from the docking station does not work since the upgrade to Windows-7. Even with the laptop plugged in, the sound always comes out of the laptop, not the headphones plugged into the docking station. Here's what I've tried: I've seen other issues like via Google this that seem to be mostly unanswered. I found one or two that referenced using the Vista x64 drivers, especially the Nvidia drivers. I do not have an Nvidia chipset but I've reinstalled the sound drivers and that has not helped. I don't have a support contract and considering the cost is usually high to call Dell, that's not an option. Dell's forums are pretty much a wasteland and I've found no help there. Since this is a docking station I thought I might need to try the SATA or Intel chipset drivers from the dell site instead, however I'm not really sure and I need to work on this laptop in the meantime. I can't really afford the downtime to experiment with random drivers all day in case they turn out to be incompatible (Dell still hasn't added Windows 7 to their support site as far as I can tell). Does anyone have any other ideas? Has anyone had this issue and solved it? If so, how? Thanks in advance for your help.

  • Replicate From OpenDJ to OpenLDAP?

    - by Joel K
    I am considering retiring some of our older OpenDJ LDAP servers and replacing with OpenLDAP. (seems to be more widely supported) I am wondering if it's possible to replicate directly from OpenDJ to OpenLDAP as an interim solution to remove the OpenDJ slaves and then flip the master over later. Is LDAP replication implementation specific or more general? I guess I'll have to just go give it a try, but I was looking for advice from someone who's been down this road.

  • Microsoft Access: computer freezes when user tries to update record

    - by CarlF
    A colleague and I have developed an Access 2003 database which is used throughout our department. Currently about four dozen people do data entry using one of two very similar forms. If 47 of us use them, they work perfectly. If Mr. 48 clicks the "Save" button, Windows XP freezes and a hard reset is needed. The problem has to be on his specific computer (Dell latitude D630) and not in the code because this problem only affects him. Complicating the matter: I don't work for IS, and this project is not supported by IS. If I'm going to get our tech support to fix the problem I had better be able to explain exactly what to do and how to do it, because they aren't going to invest any resources. I don't even have admin rights on the computer (and neither does its regular user). I've asked him to bring his laptop the next time he visits my building. (Just to make matters worse, he doesn't usually work in the same location as me or the other developer.) Any suggestions on debugging the problem? My first try will be to uninstall and reinstall Office, which I can do using corporate utilities without being admin. Note: yes, those are old versions of Office and Windows. We expect to upgrade later this year.

  • Prevent Windows from resizing all the apps on the desktop when switching monitors

    - by Greg Hewgill
    Short version: When moving my laptop and sleeping between using different monitors, all my open windows are crammed into the upper left corner as if they tried to fit on the laptop internal screen resolution. I plug in and switch to the external monitor before unlocking my session. Is there a way to prevent this automatic resizing? Longer version: I have a laptop that I move between two locations. I have one docking station, and the same kind of monitor configured for 1600x1200, in both locations. The internal laptop screen is awful so I don't use it. Location A: Docking station, monitor connected via DVI. Location B: No docking station, external monitor connected via VGA cable. In this location I have the laptop lid open for keyboard access but I don't use the laptop screen. When moving from Location A to Location B, the laptop wakes up from sleep, displaying the screen on the internal monitor. I switch to the external monitor display (using Fn+F8 on this laptop), and only after that do I unlock my session with my password. However, Windows has crammed all my nicely arranged windows into the upper left corner as if it were trying to fit them all on the laptop internal screen resolution. When moving from Location B to Location A, I have the laptop lid closed when using the docking station so Windows apparently concludes the screen resolution is 1600x1200 and doesn't resize any windows. The laptop is a Dell Latitude running Windows 7 Professional.

  • PowerShell 3.0 x64 bit broken after installing KB2506143

    - by Dave Parker
    I have searched using all kinds of variations on relevant terms and I cannot find a single other instance of someone else having this excact same problem, so I am hoping someone here may have a clue. Problem I installed Windows Management Framework 3.0 (KB2506143) by downloading and running Windows6.1-KB2506143-x64.msu from Microsoft.com. Once completed I rebooted my machine as requested. After rebooting and logging in, I try to run the 64-bit PowerShell command shell and it comes up for a second then goes away. The 32-bit shell seems to work fine, it is just the 64-bit one that fails. Looking in the Fusion logs, I found: *** Assembly Binder Log Entry (10/4/2012 @ 1:51:48 PM) *** The operation failed.

  • Wireless keeps shutting off in Windows 7

    - by Nathan Adams
    I have Windows 7 Ultimate 32bit installed on a Dell Latitude XT Tablet and for the life of me I can't figure out this really weird problem. The symptom is that the Wireless will disconnect from the AP and if I tell it to scan again, it says there are no APs in the area. I do have another wireless card in the laptop and if I disable the first one and enable the second, I am able to get onto the wireless however if I want to use the first card again I have to restart. I tried enabling/disabling the device, nothing will kick start the wireless again in the first card without a restart. I even tried different drivers. So, it seems it is random but it does occur more often when there is increased network activity (ie downloading a large file). The laptop doesn't seem to be overheating. I have tried the following: Under "Change Advanced Power Settings" for the current power profile, I set the "Wireless Adapter settings" to "Maximum Performance". Under device manger, I went to the card in question, and went to the advanced tab and set the "Power Saving mode" to "MAX_PSP" Both cards I have seem to exhibit the behavior after awhile. Both models of those cards are: Dell Wireless 1505 Draft 802.11n WLAN Mini-Card Gigabyte GN-WS30N 802.11n mini WLAN Card Has anyone have any ideas or ran into this before?

  • No boot device found. Press any key to continue

    - by Andrew Banks
    I took out the hard drive from my Dell Latitude E5420 notebook, put in an ADATA S599 solid state drive, and installed Ubuntu 11.10. When I boot, the Dell BIOS splash screen appears with a progress bar, which quickly fills up, and the screen goes black. All of this is like it was before. At this point, the OS splash screen should fade in. Instead, I was dismayed to see simply the following, in white text on a black screen: No boot device found. Press any key to continue After looking around for the Any key (just kidding) I press a key, and the Dell BIOS splash screen appears again with a progress bar, which quickly fills up, and the screen goes black. This time, however, the Ubuntu splash screen shows up, Ubuntu opens up, and all is normal. Every time I shut down, however, this happens again. It's like a game the computer and I play together. The computer has never started up without first saying: No boot device found. Press any key to continue and it has always started up after I press any key to continue. It also starts up fine if I click Restart instead of Shut Down. Thoughts?
