• Virtual box lost files

  - by Paul Lloyd

  I have been running Virtual Box on a Macbook Pro for a year or more, with an old version of Windows XP running on the virtual machine. Recently my Mac battery dies completely and I had left VB / Windows running. When I re-started the Mac, VB would not load. I reinstalled a recent download of VB from a DMG file I had stored. Now VB starts but when I try to start the virtual machine I get the following message, Failed to open a session for the virtual machine Windows XP. Failed to load VMMR0.r0 (VERR_SUPLIB_WRITE_NON_SYS_GROUP). Result Code: NS_ERROR_FAILURE (0x80004005) Component: Console Interface: IConsole {1968b7d3-e3bf-4ceb-99e0-cb7c913317bb} I have been backing up the MAC using Time Machine and have backups going back months. I really need to access the windows files as they have my Accounts and other business critical stuff. Any ideas please, or does anyone know where I can get some support for this combination of hardware / software, apologies I am a novice in this area. Thanks in advance.

• How to print TIFF files using MSFT Office Document imaging?

  - by Think Floyd

  OS: Vista and Windows7 I have Microsoft Office Document Imaging installed. .tif and .tiff files association is set to " Microsoft Office Document Imaging" When I open a TIFF file, it opens in " Microsoft Office Document Imaging". Good so far. However, when I right-click on the TIFF file and invoke print, I see a "Print Pictures" dialog, ("How do you want to print your pictures?") I have some applications installed on my machine that print incoming TIFF files on the printer. They work fine on XP. However, on Vista and Windows7, I get this "Print pictures" prompt requiring an user intervention (i.e, click on Print button). How do I get rid of this "Print Pictures" prompt?

• Help setting up NSD daemon (DNS server)

  - by Catalin

  While searching for a secure dns server I came across the NSD project. I was really impressed by what seemed to me the best option out there that's open source. One problem thought their 'tutorial' is really not beginner friendly. I have basic DNS knoledge but what's in there is out of my league. I need to have multiple sites on this CentOS server I've recently got my hands on. They also need to receive email. Details: I have a master host and would love to set this in the way described in the rows that follow: masterhost.com -> ns1.masterhost.com mail.masterhost.com www.masterhost.com addonhost.com -> ns1.masterhost.com mail.masterhost.com www.addonhost.com And so on. Any help in setting up this DNS server please? All answers and suggestions are welcomed. Thank you in advance.

• net use mapping not working in batch files but works in cmd

  - by Philippe

  Ok so here's the problem : I've got users using logon script in the domain (username.bat). The script simply lists 4 or 5 (net use letter: \\SERVER\directory\). However, when they open their session, the logon script doesnt work and returns system error 53 or 67 for all of them. I tried running the script after the profile has loaded and evrything is running, and it still gives me the error. I've then tried to run the same command in the cmd.exe. Everything mapped correctly. It also works fine if I map the drives using the "Tools Map network drives" utility. Is there anything that can prevent a command to work when ran in a batch-file but works correctly when typed in manually?

• Eclipse Pydev Ctrl-Click (Go to Definition) Doesn't Work OSX

  - by Koobz

  My Pydev set up in OS X is kind of busted. I'm working on a Django project and I find that Ctrl-Click never actually goes to the definitions of any of my objects or functions. I actually have a symlink to Django/django in my workspace so that it's easier to cross reference Django code. My guess is that something is wrong with the builder, but it doesn't throw up any errors. Does anyone have advice here? Different topic: does anyone know of a good way to use Ctrl-Shift-R (Open resource) and filter files by folder? It's not that useful in python projects where you have 20 urls.py showing up.

• How to find the static ip address of my router? [migrated]

  - by Wintermute

  I bricked my Linksys WRT54GS router when trying to change the firmware on it from dd-wrt to open-wrt. In order to unbrick it, I need to be able to do an ftp transfer to it. The problem is that it isn't using DHCP addressing and I can't just use the default ip address of 192.168.1.1. I have to use the ip address it was set at before it got bricked. The problem is I forgot what that number was. Is there some program or script that can find it out?

• Which Linux book for aspiring sysadmin?

  - by Ramy

  I have a co-worker who insists that he will never buy a book unless it is considered "THE" book. So, in this vein, I thought I'd ask what the ultimate Linux book is. I wouldn't quite call myself a complete beginner since I can get around in Linux in general pretty well. But, beyond that, I'm also looking for a book with an eye towards becoming a Sys Admin someday. I saw a Junior Sys Admin position open up recently but with the requisite 2-3 years experience, I may have to wait a little while longer before I'm ready to apply for such a position. Having said all that, I'll summarize my question: What is the ultimate Linux book for someone who is ok with the basic tasks of getting around in Linux but also wants to aim towards full Sys Admin status someday? A few examples of the books I'm considering: Linux-Administration-Beginners-Guide-Fifth Linux-System-Administration Linux-System-Administration EDIT: Before you close this question as a dup, I'd like to say that I'm looking for something that goes deeper than this: Book for linux newbies I already have "Linux in a nutshell"

• Terminal.app fonts broken on Mac Snow Leopard

  - by Fabio

  About an year ago I installed gnome fonts on my MacBook Pro and I use them for Terminal.app Today I was using Terminal with three windows open and suddenly the app has quit (I don't know if I accidentally pressed command+q) but when I reopened the application fonts looks strange. I had a screenshot taken before the accident I did the same screenshot now and here's the result I don't know what's happened, I tried to reinstall the fonts, restarted the computer, but with no luck. One more thing, I use an external screen, I read some posts regarding font issues with external monitors but I had this monitor before this accident and everything worked fine until now. Please help me to solve this because my eyes were used to that font and now it looks weird to see this different font

• Is there a plugin for default file location in sublime text 2?

  - by Vasek

  Is there a plugin (or a setting) in Sublime Text 2 to set the default file location for saving files? As of now, when I open Sublime Text 2 for the first time, create a file and try to save it, the file location option defaults to: C:\Windows\System32 I would like to set the default save file location to my Desktop so that everytime I want to save a file, the File windows opens the Desktop view. (the same idea as what can be configured e.g. in MS Word / MS Excel). Thanks for any tips!

  - by Berkay

  One of my friend has started a company, it's a small-scale company that has a 40 workers.There is two guys also responsible for the security and IT related issues.He is managing the LAN, Webpage of the company, e-mail configuration, printer hardware modification, application deployment etc. In this point, to provide the security measures including access controls, authentication, web server security etc. Which tools do you use for securing, monitoring and controlling the system ? Are you paying for these tools or are they open source? This question is due to the security administrators requests to my friend.He offers to get some tools for the company and my friend hesitates to pay that much on them (what he mentioned me.)

• Unable to outside access service from inside LAN

  - by erotsppa

  I have a weird port forwarding problem. I tried to open my port 22 to the outside network. I was able to access it as long as I am not inside the LAN. I can access it from my office for example. But from within the LAN, I can access the port using the local ip, but I can't access the port using the external IP. It's as if the router is blocking the loopback. I've check all my router settings, turned off anything firewall/filtering related. Any ideas?

• reduce timeout when connecting to wrong IP (XP-XP, windows explorer)

  - by Viki

  I have many shortcuts in the form \10.0.0.123\path in Windows Explorer (XP). Some of the IPs are sometimes dead (those vmware machines that are inactive). The problem is, when I try to open "Properties" on such shortcut (to correct the IP, or to delete it), Windows Explorer freezes for minutes. For very long time. Start menu freezes, too. This is very inconvenient. How can I reduce the windows explorer timeout when it is probing the connection to another XP share ?

• Audio input problem in Ubuntu 9.10

  - by Andrea Ambu

  My audio input is a mix of my mic output and my sound card output. I'd like it to be just my mic output. I was able to do so in Ubuntu 9.04 but the interface is 9.10 is totally changed and I tried every my creativity was able to think. It's really annoying when talking to other people over the internet because they keep hearing their voice back. I'm not sure I explained it in clear way so I'll give you an example: What I do: I put an mp3 on play or a video on youtube then open a recorder and start to talk on my mic. What happens: both my voice and audio from mp3/youtube get reordered, even if I put headphones volume to 0 (via hardware). What I'd like to happen: Only my voice should be recorded. I'm sure I'm missing some technical term, but that's the problem and I'd like to solve it in Ubuntu 9.10, any idea?

• PDF rendering issue os OSX

  - by 2Ti

  I came across some very odd rendering when trying to view a PDF file that needed to print out. I was wondering anyone has come across a similar problem before or has any ideas as to what might be causing this. PDF when viewed on OSX 10.7.4 - Preview version 6.0. I've tried opening the file in Skim but that doesn't work either. PDF as it should be, and as Chrome renders it in browser, but not if I download it onto my machine. Illustrator complains about "an unknown imaging construct" when I open the file, but renders it fine nevertheless, Photoshop doesn't have any problems either.

• Hardware asset management systems

  - by Dave

  I need to track a bunch of specialized testing tools, They are hardware devices used for testing other equipement. Each device has a serial number and is sent out for use in testing. Occasionally they break and have to be sent to the manufacture for repair. I'm looking for an open source application (preferably a webapp) to help manage them. Right now we're using Excel and it's not scaling as we get more tools. They aren't computers so all the standard IT asset management systems don't really fit the bill. I found h-harmony, but that project seems dead?

• How to generate a round-numbers graph in Excel?

  - by tcheregati

  folks! Now, I have an Excel file with measurements I made of some color patches (I work at a Press company), with a device called spectrophotometer. Here it is: https://docs.google.com/open?id=0B0i8fdSf2ihzRlFYNWd4anItenM Density and Hue are two characteristics of each color patch. The thing is: I'm looking at a non-linear increase between the 25 Color Density measurements I took, but I NEED to know exactly how the color's Hue changes as the color's Density increases. For that, I needed Excel to give me round numbers for the X axis (for example 0,70 to 1,50 in 0,05 increments). And for that, obviously, I needed Excel to calculate the probable Hue Values corresponding to those ghost/round/not-given values of Density (like a kind of advanced rule of three). So, can anyone help me on that? Thanks a lot!

• Acrobat 9.3.2 printing hidden fields automatically

  - by Noah

  We have a few clients internally running Acrobat Standard 9.0.0 and their documents are printing fine. One user upgraded to 9.3.2, and now when they try and print some of our documents, a hidden field area is automatically printing. I can't seem to find a way to turn it off. It doesn't appear in the document, or in print preview. Choosing to Examing the document and remove it removes the text, but not the spacing that the hidden area added. is there a setting to never print this? It's not something we want to have to adjust each time we open a document.

• Unmounting a zfs pool while it is shared with sharenfs

  - by Ted W.

  I have a Solaris (open indiana) system which is getting poor disk write performance. In order to enable ZIL in this version of zfs I need to add a line to /etc/system. This will not take affect until I've unmounted and remounted the zpool. The trick is that this spool is shared via nfs to about 200 other servers to host users' home directories. I can guarantee that no users will be accessing the disks during this period of maintenance but I would like to avoid having to issue an unmount for 200 systems in order to unmount the disk on the Solaris box. My question is, with sharenfs, is it necessary to have all systems disconnected before unmounting the filesystem on the host? If it's possible, how do you go about it? I've tried unmounting already, the normal way, and it reports the disk is busy. There is no lsof in Solaris and pfiles (I think that's what it was) does not show anything obviously using the mounts.

• X11 tunnelling through SSH from Fedora 3 server to Windows Vista client fails to work.

  Okay, I've tried using Xming and PuTTY, as well as Cygwin/X and Cygwin ssh, and it is not working. I've been able to run X applications locally, so it's not a client-side X problem. I've connected to the server using ssh -X user@server and ended up with this: local-user@client: ~$ ssh -X user@server user@server's password: Last login: Sun Jul 19 15:26:46 2009 from 192.168.100.147 [user@server ~]$ xclock & [1] 27770 [user@server ~]$ Error: Can't open display: localhost:10.0 [1]+ Exit 1 xclock [user@server ~]$ [user@server ~]$ Here's the relevant snippet of my sshd_config #AllowTcpForwarding yes #GatewayPorts no #X11Forwarding no X11Forwarding yes X11DisplayOffset 10 X11UseLocalhost yes I can't seem to find ssh_config on the client-side. /etc/ssh doesn't exist.

• Virus sending phishing emails through exchange server

  - by therulebookman

  It appears that there is a virus on my network somewhere that is sending phishing emails through my exchange server. I can see the messages in message tracking and I see many SMTP errors for NDR's and rejected connections from external servers, but I do not see any SMTP authentications and I have logging up to MAX. How can I find the IP or hostname of the PC that is infected? Or is there some other explanation than virus? Anti-virus scan on server is clean. Server is not an open relay. Thanks

• Disk full, du tells different. How to further investigate?

  - by initall

  I have a SCSI disk in a server (hardware Raid 1), 32G, ext3 filesytem. df tells me that the disk is 100% full. If I delete 1G this is correctly shown. However, if I run a du -h -x / then du tells me that only 12G are used (I use -x because of some Samba mounts). So my question is not about subtle differences between the du and df commands but about how I can find out what causes this huge difference? I rebooted the machine for a fsck that went w/out errors. Should I run badblocks? lsof shows me no open deleted files, lost+found is empty and there is no obvious warn/err/fail statement in the messages file. Feel free to ask for further details of the setup.

• Safari on Mac OS X Cache lasts after 'Empty Cache'

  - by Mitch

  So, I broke a website with some server changes oops. I roll back the changes I made, hit cmd-R, and oh noes, it is still broken. But I relax thinking, there must be something held in safari's cache so I press the handy 'Empty Cache' button. Hit cmd-R for refresh it is still broken. I'm really worried that I've done it and broken something bigtime. But first decide to check on a hand win xp computer, and voila it works. So the question is how do you "really" clear the cache w/o restart safari, I have many browser windows open a restart every time I make a server side change will ruin me. Any suggestions? Thanks!

• Is there such a concept as "dead thumbnails" in Windows?

  - by Pacerier

  I realised that in disk cleanup (cleanmgr.exe) there is an item "Thumbnails": Windows keeps a copy of all of your picture, video, and document thumbnails so they can be displayed quickly when you open a folder. If you delete these thumbnails, they will be automatically recreated as needed. I was pondering about why there is even an option to delete the thumbnails. Is it true that there will be "dead" thumbnails (for example if I delete a folder that has a thumbnail and the folder is deleted but the thumbnail still exists) so this option is used to clean "dead" thumbnails?
