  • Switch Text Paragraphs in OpenOfficeOrg Writer mailmerge

    - by Glen S. Dalton
    I am using mailmerge to write the same letter with minor differenes to many peolpe. I experienced that switching text paragraphs depending on database values was not easy for me. I ended up putting huge text paragraphs into the database becaus switching did not really work for me. Actually I dont' understand how writer does it and maybe the boolean evaluation is buggy? There is some possibility making paragraphs invisible depending on database fields, but it was frustrating. After marking a paragraph as invisible (depending on a condition) it went invisible in the main document and did not come back, I lost the content. An example in pseudocode of what I want in my mailmerge document: {if [[balance]] 10} We owe you money. Please can you send your bank details. {end if} {if [[balance]] < -10} Please transfer the remaining amount to our banc account 123... {end if} Maybe this could be done with makros? But how to combine makros with mailmerge? Can you tell me what are the pitfalls and how to master them? I once did this with ms word, it was a lot easier. The normal mailmerge (including database fields in the letters) works fine for me in OpenOffice writer.

  • Black screen appears when booting new install of Ubuntu 11.10 on my desktop, cannot access Grub menu to fix

    - by izn
    I installed 11.10 on my desktop PC but get a black screen after the BIOS screen when I try to boot it. I was able to run 10.04.04 on my hard drive before installing 11.10 and I am also able to use 11.10 on my usb pendrive and CD ROM. I've tried unplugging all USB devices before booting and also upgrading from 11.10 to 11.10. Holding the shift key from the BIOS screen doesn't allow me to access the GRUB menu to try: Highlight the first entry, press “e” to edit it. Navigate to words “quiet splash”, delete them and type “nomodeset” in their place (without quotes). Press Ctrl + X to continue boot. Once on the desktop, go to System Administration Additional Drivers and activate the recommended drivers. So running 11.10 on my pendrive, I tried editing /etc/default/grub, commenting out the GRUB_HIDDEN_TIMEOUT setting by putting a '#' in front of it to display the grub menu and setting GRUB_TIMEOUT setting to a value greater than or equal to 1 e.g. GRUB_TIMEOUT=10. However, when I run sudo update-grub, I get: /usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?) I get the same error with update-grub after: sudo mount /dev/sda1 /mnt and after: sudo grub-install --root-directory=/mnt /dev/sda reboot sudo update-grub Other suggestions to fix the update-grub problem: Open synaptic, then purge all the related grub installed packages and reinstall grub-pc then and finally: sudo update-grub Or use Grub Customizer http://ubuntuforums.org/showthread.php?t=1195275 What would be the best way to approach this? I'm concerned about purging "all the related grub installed packages" but if it's true some files are corrupted this would seem necessary. Also, was I executing the correct commands i.e. with mount and grub-install, before running grub-update?

  • Windows 7 AIK help

    - by microchasm
    I've just got in a few Windows 7 (64, Windows 7 Professional) machines, and I'm trying to get the AIK 2010 working. I've set up one of the machines, and installed AIK and MDT on it. I've followed the directions at http://technet.microsoft.com/en-us/library/dd349348%28WS.10%29.aspx about 3 times now, and also tried the built-in .chm help files that came with AIK. In AIK I grab the install.wim image off the OEM cd, at which point it asks me which version (I select Professional). I follow the rest of the instructions creating a new Autounattend answer file, and fill in the various bits and pieces according the the step-by-step guides. I verify the Answer file (No warnings or errors), save it, and copy it onto a USB drive. I go to another machine, insert it's OEM Win7 Disk, and power on. I've set BIOS to boot from CD, so it goes directly into the installation. Once The files are loaded, and Setup starts, it immediately asks which version to install (Home basic, Home Premium, Professiona, Ultimate). Ugh, I thought it was supposed to be an automated install, and that selecting the Version when opening the .wim file would answer this question. I looked for an option to set which version to be installed on the net, in the help, and in AIK itself; to no avail. Anyway, just for laughs I select Professional,and hit continue. It copies files for about 10 seconds, then fails with the following error: "Setup was unable to create a new system partition or locate an existing system partition. See the setup log files for more information. [OK]". Clicking OK reboots the box, and obviously there are no log files because the OS isn't installed. It is a Dell Optiplex 380 , Intel Core Duo 2.93 GHzl 4 GB RAM, 64 Bit. Any help would be REALLY appreciated.

  • Bash Script - Traffic Shaping

  • SSH garbling characters in vim/nano on remote server

    - by geerlingguy
    ... and it's driving me insane. Basically (this has been happening over the past couple months), I log into a few different CentOS servers (one Linode, another VPS, and a shared host to which I have shell access), running 5.5, 5.7, and 6, from my Mac running OS X Lion, using Terminal. Basically: $ ssh [email protected] [remote-host] $ nano somefile.txt Once I start editing the file, if I use the arrow keys to move around the cursor, or start deleting, then typing again, the cursor jumps around a bit, and if I save the file and reopen it, it's obvious that the cursor was, in fact, jumping all over the place on a line for no apparent reason. I end up getting things like "This is a neof text." When I had typed in (to the cursor-crazy editor) "This is a line of text." It's a big problem when it comes to editing configuration files, because I often have to edit one line, save and close, then reopen just to make sure that line is right... then edit another line... and it's getting quite annoying. I found Linode Lish Shell Vim and Nano rendering troubles: lines not appearing / cursor positions wrong, but I don't know if that relates much, since that's specifically referring to lish.

  • Why does my computer crash randomly?

    - by Donavon Decker
    The other day I went out to my van to get my Tower and when I opened the trunk it fell out. I brought it into the house and opened it, and everything looked ok. When I started it up, about 1-3 minutes afterwards it would crash. It did this over and over until I reseated the cooler. Everything seemed normal again, until after about 10 minutes of gameplay (any game), it would crash. I reseated my GPU + reinstalled the drivers, however I still get the same error. A while back, I'd check my 'Windows Rating' periodically, and all of them were in the '6.0-6.9' range except for my hard disk usage (always been like that [not relative]). Today I went in and looked, and my Processor and Memory was rated 5.4. I reseated my cpu and my memory, refreshed the windows rating, and then my processor and memory went from 5.4, to 5.1. A few minutes ago I reseated them once again, and now it's back to 5.4. Note: Not sure if this is relevant to the issue, but I updated my bios earlier today I honestly have no idea what the issue is, but I'm getting aggravated at the problem. Here are some images which contain images of my specifications: i1271.photobucket.com/albums/jj623/donxdeck/1_zps09f0607c.jpg i1271.photobucket.com/albums/jj623/donxdeck/4_zps381cd00a.jpg i1271.photobucket.com/albums/jj623/donxdeck/3_zps54bba720.jpg i1271.photobucket.com/albums/jj623/donxdeck/2_zps945d3d72.jpg Thanks for the help

  • Hosting a javascript api file for third party sites the way sharethis, uservoice, analytics do it.

    - by Dayson
    I'm preparing to launch a service soon which will provide third party websites a widget. The widget requires my javascript file in the website's code. Exactly the same way services like analytics, uservoice, sharethis, getclicky, etc provide you with a javascript snippet to add to your page. Therefore, my javascript file is going to be hotlinked by tons of websites which possibly receive a lot of requests too. I need advice/opinions on the following aspects: What's the right location for hosting this file? Should I use a sub-domain for it? I was thinking of something like http://api.myservice.com/js/foo.js . Remember, once websites start embedding this file, its location CANNOT change under any circumstances. Right now we can afford just one dedicated server. So I have minified my file, enabled gzip and plan to use some good cache control headers through apache. Also, in the near future when the requests pickup, I will use a http proxy like Varnish. Is this a good plan for the near future? Should I be considering a CDN in the future (since we can't afford it now)? If so how do I make sure we're prepared to migrate to it without breaking services. Pros/Cons of moving just this file to a CDN? Also, since its just one javascript file(50kb), any affordable CDN so we could consider it in the beginning itself? Any other word of advice I could use? Anything I shouldn't overlook at this stage which I would regret later? (both in terms of server + javascript ajax limitations) Thanks in advance.

  • Excel: conditionally format a cell using the format of another, content-matching cell

    - by Eric A. Meyer
    I have an Excel spreadsheet where I’d like to be able to create a “key” of formatted cells with unique values, and then in another sheet format cells using the key formatting. So for example, my key is as follows, with one value per cell and the visual formatting indicated in parentheses: A (red background) B (green background) C (blue background) So that’s on one sheet (or in a remote corner of the current sheet—whichever is better). Then, in an area that I mark for conditional formatting, I can type one of those three letters and have the cell where I typed it visually formatted according to the key. So if I type a “B” into one of the conditionally formatted cells, it gets a green background. (Note that I’m using backgrounds here solely for ease of explanation: ideally I want to have all visual formatting copied over, whether it’s foreground color, background color, font weight, borders, or whatever. But I’ll take what I can get, obviously.) And—just to make it extra-tricky—if I change the formatting in the key, that change should be reflected in cells that reference the key. Thus, if I change the “B” formatting in the key from a green background to a purple background, any “B” in the main sheet should switch to the new color. Similarly, it should be possible to add or remove values from the key and have those changes applied to the main data set. I’m okay with the formatting-update-on-key-change being triggered by clicking a button or something. I suspect that if any of this is possible it will require VBA, but I’ve never used it so I’ve no idea where to start if that’s the case. I’m hoping it’s possible without VBA. I know it’s possible to just use multiple conditional formats, but my use case here is that I’m trying to create the above-described capability for someone who isn’t conversant with conditional formatting. I’d like to let them be able to define a key, update it if necessary, and keep on truckin’ without me having to rewrite the spreadsheet’s formatting rules for them. --- UPDATE --- So I think I was a bit unclear about my original request. Let me try again with an image. The image shows the “key” on the left, where values and styles are defined using keyboard and mouse input. On the right, you see the data that should be formatted to match the key. Thus if I type a “C” into a cell in the Data area, it should be blue-backed. Furthermore, if I change the formatting of “C” in the Key to have a purple background, all the “C” cells should switch from blue to purple. For further craziness, if I add more to the Key (say, “D” with a yellow background) then any “D” cells will be styled to match; if I remove a Key entry, then matching values in the Data area should revert to default styling. So. Is that more clear? Is it possible, in whole or in part? I don’t have to use conditional formatting for this; in fact, at this point I suspect I probably shouldn’t. But I’m open to any approach!

  • Convert HTACCESS mod_rewrite directives to nginx format?

    I'm brand new to nginx and I am trying to convert the app I wrote over from Apache as I need the ability to serve a lot of clients at once without a lot of overhead! I'm getting the hang of setting up nginx and FastCGI PHP but I can't wrap my head around nginx's rewrite format just yet. I know you have to write some simple script that goes in the server {} block in the nginx config but I'm not yet familiar with the syntax.

  • Application losing Printer within Terminal Services for remote users

    - by Richard
    Question: What I need to do is have a permanent link to a printer, normally only accessible through Terminal Services (Printer Redirect), to allow Sage Line 50 layouts to see that printer persistently, even after users have disconnected and reconnected to the Terminal Services session? Although the printer is accessible each time a user connects to the Sage Server via Terminal Services, it is given a different session number and therefore the Sage Layout sees it as a different printer. History behind question: Users using Terminal Services connecting to a Sage Server on a different site Using Sage Line 50 v 15 on that Server Users want to print invoices (sage layouts) locally Sage Server cannot see the users local printers, to get around this user uses the Print redirect features of Terminal Services The individual reports can be edited to point to a specific printer by default. This means the user just has to select an invoice and click print, then select the layout/report wanted and it auto prints that invoice to the default printer specified. The problem occurs because the layouts are edited to point to the users local printer "Ricoh 1018d (session#)", note the "(session#)" as this is the users local printer being redirected through the terminal services session. Users are able to print using the sage layouts once the default printer is setup within the layout and saved, but as soon as the users disconnects from the Terminal Services session and then reconnect in the morning go to print, it has lost the connection to that printer. I understand why its failed, because that the printer is on a per session basis and the layout would not be able to hold on to the connection from a previous session. Thanks in advance for any assistance...

  • Trouble serving vhosts when trying to set up wildcard subdomains with dnsmasq in local development e

    - by Jeremy Kendall
    I'm trying to get wildcard DNS enabled on my laptop using dnsmasq. I realize that this has been asked and answered more than once on this forum, but I can't get the solution to work for me. Steps taken so far: Installed dnsmasq Set address=/example.dev/127.0.0.1 in dnsmasq.conf Set listen-address=127.0.0.1 in dnsmasq.conf Ensured nameserver 127.0.0.1 is in /etc/resolv.conf Set prepend domain-name-servers 127.0.0.1; in /etc/dhcp3/dhclient.conf Created a vhost for example.dev Restarted apache and dnsmasq Note: example.dev is not set in /etc/hosts My vhost for example.dev <VirtualHost *:80> ServerName example.dev DocumentRoot /home/jkendall/public_html/example/public ServerAlias *.example.dev # This should be omitted in the production environment SetEnv APPLICATION_ENV development <Directory /home/jkendall/public_html/example/public> DirectoryIndex index.php AllowOverride All Order allow,deny Allow from all </Directory> </VirtualHost> The setup above will server example.dev locally without any problem. It will also serve test.example.dev, but test.example.dev returns the default apache "It works!" index.html from /var/www rather than my index.php in /home/jkendall/public_html/example/public. The solution in this Server Fault thread suggests that address=/.example.dev/127.0.0.1 would resolve my problem, but when I try to use that solution, restarting dnsmasq results in a failure with the error message dnsmasq: error at line 62 of /etc/dnsmasq.conf For grins, I moved my project over to /var/www/example and modified the vhost appropriately. I got the same result as described above. At this point I'm not sure what other steps I can take to resolve the issue. Thoughts?

  • Dynamically add Server 2008 NLB Nodes

    - by Nick Jacques
    Hi All, I have a small NLB cluster for Terminal Servers. One of the things we're looking at doing for this particular project (this is for a college class) is dynamically creating Terminal Servers. What we've done is create policies for a certain OU, that sets the proper TS Farm properties and installs the Terminal Server role and NLB feature. Now what we'd like to do is create a script to be run on our Domain Controller to add hosts to the preexisting NLB cluster. On our Server 2008 R2 Domain Controller, I was thinking of running the following PowerShell script I've kind of hacked together. Any thoughts on if this will work? Is there any way I can trigger this script to run on the DC once all the scripts to install roles are done on the various Terminal Servers? Thanks very much in advance!! Import-Module NetworkLoadBalancingClusters $TermServs = @() $Interface = "Local Area Connection" $ou = [ADSI]"LDAP://OU=Term Servs,DC=example,DC=com" foreach ($child in $ou.psbase.Children) { if ($child.ObjectCategory -like '*computer*') {$TermServs += $child.Name} } foreach ($TS in $TermServs) { Get-NlbCluster 172.16.0.254 | Add-NlbClusterNode -NewNodeName $TS -NewNodeInterface $Interface }

  • How can I stream audio signals from various devices/computers to my home server?

    - by Breakthrough
    I currently have a headless home server set up (running Ubuntu 12.04 server edition) running a simple Apache HTTP server. The server is near an audio receiver, which controls a set of indoor and outdoor speakers in my home. Recently, my father purchased a Bluetooth adapter, which our various laptops and cellphones can connect to, outputting the music to the speakers. I was hoping to find a solution that worked over Wi-Fi, namely because it won't cost anything (I already have a server with an audio card), and it doesn't depend on Bluetooth. Is there any cross-platform (preferably free and open-source) solution that I can use which will allow me to stream audio to my home server, over my home network, from a wide variety of devices (laptops running Windows/Linux or cellphones running Android/BB/iOS)? I need something that works at least with Windows and Android. Also, just to clairfy, I want something that simply allows devices to connect to my server and output an audio signal without any action on the server end (since it's a server hidden away near my receiver). Any subsequent connection attempt should be dropped, so only one device can be in control of the stereo at once.

  • FTP on Linux "Failed to retrieve directory listing" not firewall issue

  • PPTP connection fails with errors 800/806

    - by Mark S. Rasmussen
    I've got a client (Server 2008 R2) that won't connect to our production environment PPTP VPN server (Server 2003, running RRAS). The server is behind a firewall that has TCP1723 open as well as GRE. Other clients at our office are able to connect just fine. Our office is behind a Juniper SSG5-Serial firewall, but all outgoing traffic is allowed, and multiple other clients are able to connect to VPN servers without issues. I've also setup a completely different VPN server on another network outside of our office. The functioning clients connect just fine - the Server 2008 R2 machine doesn't. Thus it's definitely a problem with this machine in particular. I've rebooted it. I've disabled the firewall, no dice on either. I've run PPTPSRV and PPTPCLNT on the server/client and they're able to communicate perfectly - indicating there's no problem using neither TCP1723 nor GRE. The Server 2008 R2 machine is also running as a VPN server itself (incoming connection) and that's working perfectly. We have the issues no matter if there are active incoming connections or not. I'm not sure what my next debugging step would be; any suggestions? EDIT: The event log on the server has the following warning from RasMan: A connection between the VPN server and the VPN client xxx.xxx.xxx.xxx has been established, but the VPN connection cannot be completed. The most common cause for this is that a firewall or router between the VPN server and the VPN client is not configured to allow Generic Routing Encapsulation (GRE) packets (protocol 47). Verify that the firewalls and routers between your VPN server and the Internet allow GRE packets. Make sure the firewalls and routers on the user's network are also configured to allow GRE packets. If the problem persists, have the user contact the Internet service provider (ISP) to determine whether the ISP might be blocking GRE packets. Obviously this points to GRE being a potential problem. But seeing as I have other clients connectiong without problems, as well as PPTPSRV and PPTPCLNT being able to communicate, I'm suspecting this might be a red herring. EDIT: Here are the anonymized events logged by the client in chronological order: CoId={742CB15C-A7E0-47B7-8240-0EFA1139CBD9}: The user XXX\YYY has started dialing a VPN connection using a per-user connection profile named ZZZ. The connection settings are: Dial-in User = XXX\YYY VpnStrategy = PPTP DataEncryption = Require PrerequisiteEntry = AutoLogon = No UseRasCredentials = Yes Authentication Type = CHAP/MS-CHAPv2 Ipv4DefaultGateway = No Ipv4AddressAssignment = By Server Ipv4DNSServerAssignment = By Server Ipv6DefaultGateway = Yes Ipv6AddressAssignment = By Server Ipv6DNSServerAssignment = By Server IpDnsFlags = Register primary domain suffix IpNBTEnabled = Yes UseFlags = Private Connection ConnectOnWinlogon = No. CoId={742CB15C-A7E0-47B7-8240-0EFA1139CBD9}: The user XXX\YYY is trying to establish a link to the Remote Access Server for the connection named ZZZ using the following device: Server address/Phone Number = XXX.YYY.ZZZ.KKK Device = WAN Miniport (PPTP) Port = VPN3-4 MediaType = VPN. CoId={742CB15C-A7E0-47B7-8240-0EFA1139CBD9}: The user XXX\YYY has successfully established a link to the Remote Access Server using the following device: Server address/Phone Number = XXX.YYY.ZZZ.KKK Device = WAN Miniport (PPTP) Port = VPN3-4 MediaType = VPN. CoId={742CB15C-A7E0-47B7-8240-0EFA1139CBD9}: The link to the Remote Access Server has been established by user XXX\YYY. CoId={742CB15C-A7E0-47B7-8240-0EFA1139CBD9}: The user XXX\YYY dialed a connection named ZZZ which has failed. The error code returned on failure is 806. Running Wireshark on the client shows it trying and retrying to send a "71 Configuration Request" While the server shows the incoming client requests, but apparently without replying: Given that this is GRE traffic, I think rules out the GRE traffic being blocked. Question is, why doesn't the server reply? This is the Configuration Request the server receives from the non functioning client (meaning no response is sent to the client request): And this is the Configuration Request the server receives from the working client: To me they seem identical, except for differing keys and magic numbers, and the fact that one client receives a response while the other doesn't.

  • Sharing large (multi-Gb) files with clients

    - by Tim Long
    I wasn't sure if this was the best place for this question, but I think it is squarely in the realm of the IT admin so that's the reason I put it here. We need to share large files (several Gigabytes) with external clients. We need a simple way of reliably and automatically publishing these files so that clients can then download them. Our organization has Windows desktops and a Windows SBS 2011 server. Sharing from our server is probably suboptimal from the client's perspective, because of the low upstream bandwidth of typical ADSL (around 1 Mbps) - it would take all day (9 hours for a 4Gb file) for the client to download the file. Uploading to a 3rd party sever is good for the client but painful for us, because we then have to deal with a multi-hour upload. Uploading to a third-part server would be less problematic if it could be made reliable and automatic, e.g. something like a Groove/SharePoint Workspace, simply drop the file in and wait for it to synchronize - but Groove has a 2Gb limit which is not big enough. So ideally I'd like a service with the following attributes: Must work for files of at least 5Gb, preferably 10Gb Once the transfer is started, it must be reliable (i.e. not sensitive to disconnections and service outages) and completely automatic Ideally, the sender would get a notification when the transfer completes. Has to work with Windows based systems. Any suggestions?

  • Can't connect two PCs to a Network Switch at the same time (Windows 7)

    - by puk
    I have two computers connected to a network switch and every once in a while one of the computers will lose its internet connection. It's almost always the same computer every time. However, if I play around with the control panel, I can switch it, so that now the other computer is not connected. Restarting either of the computers does not help either. In Windows, the worlds-greatest-trouble-shooter tells me that a network cable is unplugged and that I should try plugging it in...Disabling and re-enabling my NIC does not fix this problem, neither does swapping cables around. When rebooting, the BIOS complains about how the Ethernet Cable is not plugged in. If it's in any way important, My set up at the office is like so: Modem - Routher - Network Switch 1 - Network Switch 2. I have tried turning off the energy saving option for my NIC, and I tried manually setting the link-speed to 100Mbps Full Duplex without any luck. Also, I have a Realtek PCIe GBE Family controller on both computers Does anyone have any idea why this is happening every 5-10 days? EDIT: I have also tried using a completely different Network Switch and the problem still persists as before.

  • How can I do an SELINUX filesystem relabel without rebooting first?

    - by Skaperen
    I can touch the file /.autorelabel and reboot and during the initialization coming back up it will do the SELINUX relabel for me. But I want to do this in a different situation where the system has just been copied to a hard drive image. I can chroot to the originating file tree, or chroot to the just populated device image and run it. I just can't find anything that says what to be run. This image is being made into an AMI on AWS EC2, and contains CentOS 6.3. But the time it takes to relabel is too long (6 minutes or more). I want to move the relabel to the image build where the extra time is not an issue (because it happens once instead of every time an AMI is launched). I can make this relabel be the very last thing just before the filesystem is unmounted for the last time until it becomes an AMI and will launch. I just need to know what to call to do it. I have searched man pages with no luck. I have searched system init scripts but where /.autorelabel is detected, it is unclear what is happening. Documents like http://www.centos.org/docs/5/html/5.2/Deployment_Guide/sec-sel-fsrelabel.html only tell how to do things that still really do the work after a reboot. I need to have the work doing BEFORE the "reboot" (unmount, build AMI, and launch ready to go). The big point is ... yes there will be a reboot ... but I want the relabel work to be done before that so it won't be done every time an AMI is launched (because it takes so long).

  • problem booting crusty old windows XP

    - by Carson Myers
    I have an acer aspire laptop running Windows XP home. I believe I have some virus on it, I'm not sure--I mostly just run linux in a VM on it so I wasn't too worried. I'm not sure if that virus caused this problem. The laptop wasn't recognizing my USB hard drive for some reason so I decided to restart it. When it started up, it got past the memory test, past the boot screen, (but it paused right here on a blank screen for awhile) and flashed the desktop once (like it does just before the login screen) and then crashed. I got a quick BSOD and then it restarted. Then it tried to boot again, etc etc infinite loop of failure. Well, before trying safe mode, I disabled automatic restart on system crash so I could read the blue screen. There wasn't anything important on it, it said *** STOP: 0x00000000 (0xC0000000 0x,.... ) beginning physical memory dump physical memory dump complete That's not verbatim (obviously) but it didn't help me. so I booted in safe mode, and it stopped on the driver gagp30kx.sys and then restarted (and infinite loop of failure again). I burned a recovery CD and tried that. It loaded it, and I went into repair mode. I ran chkdsk and then disabled the AGP driver. Same thing on booting in safe mode except it stopped at mup.sys instead. I enabled the AGP driver again, and ran chkdsk again from the CD. It said it found problems but didn't say it fixed them. So I ran it a second time, and it said "performing additional checking or recovery" lots of times (I can't tell how many, they went above the screen top). I tried booting again and no luck. Every time I run chkdsk after trying to boot again it says it found and fixed more errors. I think it might be whatever driver is after the AGP driver, but I don't know what it is or how to find out. Can anyone help me fix this?

  • Users suddenly missing write permissions to the root drive c within an active directory domain

    - by Kevin
    I'm managing an active directory single domain environment on some Windows Server 2008, Windows Server 2008 R2 and Windows Server 2012 machines. Since a few weeks I got a strange issue. Some users (not all!) report that they cannot any longer save, copy or write files to the root drive c, whether on their clients (vista, win 7) nor via remote desktop connection on a Windows Server 2008 machine. Even running programs that require direct write permissions to the root drive without administrator permissions fail to do so since then. The affected users have local administrator permissions. The question I'm facing now is: What caused this change of system behavior? Why did this happen? I didn't find out yet. What was the last thing I did before it happened? The last action that was made before it happened was the rollout of a GPO containing network drive mappings for the users depending on their security group membership. All network drives are located on a linux server with samba enabled. We did not change any UAC settings, and they have always been activated. However I can't imagine that rolling out this GPO caused the problem. Has anybody faced an issue like that? Just in case: I know that it is for a specific reason that an user without administrative privileges is prevented from writing to the root drive since windows vista and the implementation of UAC. I don't think that those users should be able to write to drive c, but I try to figure out why this is happening and a few weeks ago this was still working. I also know that a user who is a member of the local administrators group does not execute anything with administrator permissions per default unless he or she executes a program with this permissions. What did I do yet? I checked the permissions of the affected programs, the affected clients/server. Didn't find something special. I checked ALL of our GPOs if there exist any restrictions that could prevent the affected users from writing to the root drive. Did not find any settings. I checked the UAC settings of the affected users and compared those to other users that still can write to the root drive. Everything similar. I googled though the internet and tried to find someone who had a similar problem. Did not find one. Has anybody an idea? Thank you very much. Edit: The GPO that was rolled out does the following (Please excuse if the settings are not named exactly like that, I translated the settings into english): **Windows Settings -- Network Drive Mappings -- Drive N: -- General:** Action: Replace **Properties:** Letter: N Location: \\path-to-drive\drivename Re-Establish connection: deactivated Label as: Name_of_the_Share Use first available Option: deactivated **Windows Settings -- Network Drive Mappings -- Drive N: -- Public: Options:** On error don't process any further elements for this extension: no Run as the logged in user: no remove element if it is not applied anymore: no Only apply once: no **Securitygroup:** Attribute -- Value bool -- AND not -- 0 name -- domain\groupname sid -- sid-of-the-group userContext -- 1 primaryGroup -- 0 localGroup -- 0 **Securitygroup:** Attribute -- Value bool -- OR not -- 0 name -- domain\another-groupname sid -- sid-of-the-group userContext -- 1 primaryGroup -- 0 localGroup -- 0 Edit: The Error-Message of an affected users says the following: Due to an unexpected error you can't copy the file. Error-Code 0x80070522: The client is missing a required permission. The command icacls C: shows the following: NT-AUTORITY\SYSTEM:(OI)(CI)(F) PRE-DEFINED\Administrators:(OI)(CI)(F) computername\username:(OI)(CI)(F) A college just told me that also the primary domain-controller (PDC) changed from Windows Server 2008 to Windows Server 2012. That also may be a reason. Any suggestions?

  • how to run multiple shell scripts in parallel

    - by tom smith
    I've got a few test scripts, each of which runs a test php app. Each script runs forever. So, cat.sh, dog.sh, and foo.sh, each run a php script, and each shell script runs the php app in a loop, so it runs forever, sleeping after each run. I'm trying to figure out how to run the scripts in parallel, and at the same time, see the output of the php apps in the stdout/term window. I thought, simply doing something like foo.sh > &2 dog.sh > &2 cat.sh > &2 in a shell script would be sufficient, but it's not working. foo.sh, runs foo.php once, and it runs correctly dog.sh, runs dog.php in a never ending loop. it runs as expected cat.sh, runs cat.php in a never ending loop *** this never runs!!! it appears that the shell script never gets to run cat.sh. if i run cat.sh by itself in a separate window/term, it runs as expected... thoughts/comments

  • Get details / solve issue with a kernel panic?

    - by Joseph
    I have a Lenovo T430 running Linux Mint 13 (MATE): joseph:~$ uname -a Linux joseph-T430-LM 3.2.0-23-generic #36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux I installed Mint immediately after getting the laptop about two weeks ago, and have noticed that about once a day, the computer will completely freeze up- I can't use Ctrl+Alt+Backspace to restart X, I can't use Ctrl+Alt+F1 to get a text only terminal, can't move mouse, can't type, and if any music was playing it just gets stuck in about a 1-second loop. There is a Windows partition, but I haven't had any issues in Windows. I couldn't find a common thread between the freezes, they were seemingly random (sometimes right after I clicked the mouse, sometimes not; sometimes with Pandora/flash being used, sometimes not, etc). I assume they're kernel panics since it completely locks up, but the laptop doesn't have a capslock or scroll lock LED. It is on a dock and I do have a USB keyboard, but the scroll lock/capslock lights do not flash when it happens (not sure if this is indicating its not a kernel panic, or if the kernel panic just wouldn't illuminate the LEDs on a usb keyboard attached to a laptop dock). This was annoying but not terrible. However, I've found a way to reproduce it. I have a particular CSV file that when I open up in LibreOffice Calc and scroll around, the same thing happens- complete lock up. I really need to use this file, so I'd like to fix the issue, but at the least it's given me a test case to work with. So, having a case where I can cause this issue, what can I do to better find out what's going on? I've looked in /var/log/syslog but haven't found anything seemingly useful. Any thoughts?

  • Flash plugin locks up Firefox, Chrome and Safari behind a corporate proxy, IE6 works fine

    - by Shevek
    At work I am forced by corporate policy to use IE6. Obviously this is not so good so I use FF for most of my browsing. However there is a problem once I have installed the Flash plug-in - FF locks up when trying to load Flash media. Looking at the status bar at the time of the lock up it appears this happens when the browser tries to get cross domain data. The Flash Active X plug-in in IE does not suffer this issue. I have tried it in a brand new profile in FF with Flash as the only plug in and it locks up. We have 2 different proxy servers and both exhibit the same problem. I have also tried Chrome and Safari and both lock up with the plug-in installed. So, has anyone else had this problem and solved it? Or, is there any way to disable cross domain data access in the flash plug-in? Or, is there any way to disable the "This site needs an additional plug-in" ribbon which appears when the plug-in is not installed. Many thanks!

  • route propogation using OSPF in a network

    - by liv2hak
    I am using Juniper J-series routers to emulate a small telco and VPN customer.The internal routing will be configured with OSPF,MPLS including a default and backup path,RSVP for distributing labels withing the telco,OSPF for distributing routes from the customer edge (CE) routers to the VRF's in the adjacent PE's and finally iBGP for distributing customer routes between VRF's in different PEs. The topology of the network is shown below. The Addressing scheme for the network is as follows. UOW-TAU ******* ge-0/0/0 192.168.3.1 TAU-PE1 ******* ge-0/0/0 10.0.1.0 ge-0/0/1 10.0.2.0 ge-0/0/2 192.168.3.2 TAU-P1 ****** ge-0/0/0 172.16.1.0 ge-0/0/1 172.16.3.1 ge-0/0/2 10.0.2.2 HAM-P1 ****** ge-0/0/0 172.16.3.2 ge-0/0/1 172.16.2.1 ge-0/0/3 10.0.3.2 ACK-P1 ****** ge-0/0/0 172.16.1.2 ge-0/0/2 172.16.2.2 ge-0/0/3 10.0.1.2 HAM-PE1 ******* ge-0/0/0 10.0.3.1 ge-0/0/2 192.168.4.2 UOW-HAM ******* ge-0/0/0 192.168.4.1 I also set up loopback address for each node. I want to setup OSPF so that path to each internal subnet and router loopback address is propogated to all PE and P nodes.I also want to select a single area for PE and P nodes,and on each node I should add each interface that should be propogated. How do I accomplish this.? With my understanding below is the procedure to achieve this.Is the below explanation correct? I set up OSPF on UOW-TAU ge-0/0/0 interface and ge-0/0/1 interface and UOW-HAM ge-0/0/0 interface and ge-0/0/1 interface. let me call this Area 100. Once I have done this I should be able to reach each node from others using ping and traceroute. Any help is highly appreciated.
