• Out of memory errors but not actually out of memory...

  - by commradepolski

  So, myself and my fellow support techs have been fighting with this issue and we still dont know what the problem is. Lets start off with the system specs: Windows XP 32 bit Corporate (SP2 and SP3) Intel D975XBX2 Mobo 4gb of ram Intel Core 2 Quad Q6600 ATI Radeon HD 3600 - 512mb After a few hours of working on the machine, the end user will begin to see the following symptoms: Out of memory messages Title bars and menus dont draw in properly Problems accessing network resources Problems opening up documents such as MSWord and MSPowerpoint and text files Problems opening up explorer windows General instability We have looked at task manager while this issue was occurring, and all indicators, like PF usage, threads, handles, etc. are normal. We have been having trouble pinpointing the root cause of this issue. It is also not situated with one user, it affects 8-10. So far we have tried: Resetting CMOS (Waiting to see results) Replacing video card (didnt help) Windows updates (didnt help) Updating network drivers (didnt help) Switching user from 1gbps to 100mbps network connection (awaiting results) Swapping the affected user's hardware (waiting for results) Increasing desktop heap size (helped for a bit but then the issue became more frequent) Applying the /3 switch to XP (didnt help) Increasing and decreasing and setting PF to system managed state (didnt help) We did have a power outage at the office a couple weeks ago, and all these issues became more frequent. Prior to the power outage it may take a week or so for the users to experience the issues but since the power outage it takes 3-4 hours or less. We havent had reports of the above issues causing BSODs, although that would be easier to diagnose :). Any help is greatly appreciated.

• Application that will identify percentage of your system disk bandwidth used on a user-application by user-application basis?

  - by Warren P

  I always (subjectively) feel my computer is far too slow (however fast it is), and so I'm always looking for ways to measure and understand what my computer is actually doing, that is making it seem "slow" to me. It has been my observation that my software-developer workload is most often disk-bound (I am waiting for Disk I/O) more than CPU bound. What has made it worse, is that I am using a corporate PC that has in-memory active-scanning anti-virus software that I do not have control over, and also some IT department mandated services that seem to suck up a lot of available hard-disk bandwidth. The best tool I have seen (in Windows 7) is the Resource Monitor which I usually acess from the button in the task Manager. The disk IO page, however, seems to label Disk Activity at a very low level (for example, showing the Volume Shadow Storage, which is flushing information obviously written by something ELSE other than VSS itself, and then writes to Pagefile.sys, which are obviously due to Virtual Memory faults in some application). What I would like to know is if a utility exists that can add up all direct disk input and output by user-level process, or find the process or service that caused VM or VSS activity. In that way, I hope, you could establish a real idea of how much of your computer's precious disk subsystem bandwidth is attributable to a particular application. here's a scenario: MyApp.exe writes 100k/s and reads 100k/s directly. VSS ends up writing another 100k/s. pagefaults caused inside MyApp.exe cause another 100k/s of writes. So the total "cost" of MyApp.exe running, during a period of time (let's say 1 second) is 400k/s, whereas you can only directly observe half of that, in Resource Monitor. Is there a smarter disk-IO watching piece of software I can use?

• Creating a Logical network diagram

  - by user273284

  Im a student and I have been assigned the task of creating a logical network diagram for the following scenario There are 2 buildings, the first is the head office and the second is the branch. The data centre is in the head office, it contains domain controller, mail server, file server and a web server. it provides wired and wireless access to the staff. the branch building is new and it does not have a network. The two buildings must be connected using a VPN connection. The branch building will not have any servers but just network devices that will provide the connectivity, the users in the branch building will be connected to the head office over the VPN. I had created a diagram based on this scenario, but my teacher rejected it saying that it does not follow Cisco hierarchical Model and the servers were not placed correctly in the diagram. I just wanted some help in this matter so that I Can create my network diagram correctly. If anyone could upload a picture of how the logical diagram should be for this scenario will be helpful, any other resources would also be great.

• Free blog sites where the blogs can (if the template does) validate as XHTML Strict 1.0?

  - by Deleted

  I'm looking for a site where I may register a free blog and have the blog validate as XHTML Strict 1.0. On the surface this may seem like a trivial problem only related to the theme/template in use, but that's unfortunately not the case. One example of a provider which can't fullfill this requirement is Blogger. Altough the pages of the blogs there presents themselfs as XHTML 1.0 Strict it is impossible to actually comply with the requirements inheritied by that markup type in the blog (as the XHTML which is generated by Blogger makes the page as a whole invalid). I've sent a mail to Tumblr to see if it was possible with them, but so far my reply consists of them having forwarded my mail with a "suggestion" to the development department. I don't know if we had a communication error or if I'm actually going to receive a proper answer later. Time will tell. I haven't had time to investigate Tumblr myself, so they may very well be the solution to this problem. To sum things up, I'm looking for any provider: Of a free blog. The blog must have the capability to validate as XHTML Strict 1.0. With capability I mean that the system shouldn't get in the way of creating/using a theme which complies as XHTML Strict 1.0. Preferably is large or at least likely to stay around for a couple of years to come. But I'm willing to take my chances if none of the established providers are up to the task. Thank you for reading! I hope you know of any provider which would be suitable, preferably with proof by linking to a blog there which validates. I'm not looking for suggestions to look into, as there are far to many to investigate and far too little time. If you know of something for sure, I'd be very happy to know about it.

• New AD user request form and workflow

  - by user66390

  I'm wondering if anyone is providing a solid solution for creating New Network User Account Request forms, and attaching workflows to them to automate account creation? I'm currently investigating a number of options, but am surprised that such a ubiquitous task hasn't been solved a dozen times over and thoroughly documented. Or at least isn't integrated into current off-the-shelf change management and ticketing systems. Ideally, I'd like for our current ticketing system, ServiceDesk+ to present a standard 'New User' form to department heads, which they can fill in with the required new user details. This triggers a workflow that submits the request as a ticket that can be reviewed and actioned. Actioning the ticket triggers a workflow that creates a user in AD with the details provided, and notifies the department head upon completion. All told, a pretty standard requirement that I'm sure most organizations have. What are other people doing to accomplish this? Edit: I should add, I'm more looking for "supported" methods. As is, I've submitted a number of scripted solutions, none of which have met with manager approval.

• Batch-Remove Specific Text from Photo Descriptions

  - by David

  I've recently upgraded to iPhoto '11 (couldn't resist the pricing on the new app store) and as I'm adding more meta-data to my library and generally organizing things (places, faces, etc... I hadn't upgraded since '08) I've noticed something odd in my photos. Every photo in my library has a description (though many are short), but it would appear that somehow the description of one of the photos has been appended to many. I don't know if maybe I accidentally screwed up a batch change at some point in the past, or if the library upgrade somehow messed up, or what else may have happened. But what I need to do is fix these somehow. Now, manually editing is something of a daunting task. Within a library of 21,248 photos, 18,858 of them have this additional text. The one thing I do have going for me is that it's a specific string. If there's a way to "remove this string from everywhere in the library without removing the rest of any given description" then that would be perfect. Is there anything I can do like this? Maybe even manually editing a library file in a text editor? (Would that break anything else in iPhoto if its library was edited outside of the application, even while it's not running?) Does anybody have any ideas?

• Revamping an old and unstable office IT-solution using Windows Server and OpenVPN

  - by cmbrnt

  I've been given the cumbersome task to totally redo the IT-infrastructure for a customer's office. They are currently running Windows XP all over, with one computer acting as a file server with no control over which users have access to which files, and so on. To top it off, this file server also functions as a workstation, which means it gets rebooted every time the user notices some sluggish behavior or experiences problems with flash games. To say the least, this isn't working for them. Now - I've got a very slim budget, but I need to set up a new server, and I wish to run Windows Server 2008 on it. I also need the ability to access the network remotely via VPN. Would it be a good idea to install VMware ESXi 4.1 onto the new server, and then run Windows Server 2008 as well as a separate Debian install for openvpn on it? I don't like the Domain Controller for the future AD to also run a VPN-server, because of stability issues when something goes to hell with either of them. There will be no redundancy though. However, I'm not sure if there is something to gain by installing a VPN solution on the Windows Server itself, when it comes to accessing file shares on the network via VPN. I don't know how to enable users logging in via the VPN to access the remote files, since they will be accessing the network from their own home computers (which is indeed a really bad idea, but this is what I've got to work with). They won't be logged in to the windows Domain, but rather their home workgroups. I need to be able to grant access to files in certain directories based on the logged in AD-user, but every computer won't necessarily be configured to log into the domain. I'm not sure how to explain this in a good way, but I'd be happy to clarify if somethings not clear. Any help would be great, because I've got a feeling that I can't do this without introducing a bunch of costly new rules when it comes to their IT-solution. I'd rather leave that untouched and go on my merry way to the next assignment.

• System randomly freezes yet mouse still moves

  - by user784446

  This problem has lasted for the past 48 hours. The first time it happened, a program I was running stopped responding, so I tried to end it from task manager. The processes at first were listed fine until hovered upon. Eventually, despite the mouse still being able to move, after a few persisting clicks the mouse finally stopped moving. The screen went blank shortly thereafter. The second time it occurred, items on the screen stopped responding - hovering over the taskbar or such wouldn't elicit a response. Sound would still play however. Eventually, the mouse became unresponsive and the system restarted itself. I suspect that it may be a problem of my SSD drive. After looking through some Google search results, I downloaded HDTunePro to determine if there's a problem with the drive. Results returned a problem of reallocated sector count. An error scan also revealed 48 bad sectors. Also, an attempt to backup the contents of the most important areas of the drive returned a few explorer "Error: cannot read source from disk" errors. Should I ditch the drive and use another drive or is there anything that can be done to repair the drive? SSD: OCZ Petrol 64gb CPU: AMD Athlon II X4 640 RAM: Generic 3GB DDR2 Motherboard: Gigabyte MA74GM-S2H OS: Windows 7 Ultimate x64 Thanks!

• Disable Windows 7 taskbar grouping. Not combining.

  - by Byran

  I've look near and far but I cannot find a way (setting or hack) to prevent Windows 7 from grouping taskbar buttons together that are "related". I'm not talking about the option to combine or collapse related buttons into one item. I can find that setting at: Taskbar and Start Menu Properties Taskbar Taskbar buttons: This is what I an not looking for: How to Enable or Disable Windows 7 Taskbar Button Grouping I'm talking about how Windows 7 seams to think that it's doing me a favor by grouping all my Google Chrome buttons together and grouping all my Explorer buttons together etc. My workflow in Windows XP was to use the program Taskbar Shuffle to allow me to reorganize my taskbar buttons into related task "groups" I was working on. For example: [Start Button] | [iTunes] [Outlook Express] [Chrome Gmail] [layered design folder] [Photoshop CS4] [exported images folder] [website root folder] [Dreamweaver CS4] [Chrome www.MyAwesomeWebsiteImBuilding.com] [Chrome Recent web search] [some unrelated folder] Windows 7 doesn't seem to let me do this. It wants to do: [Start Button] | [layered design folder][exported images folder][website root folder][some unrelated folder] | [Chrome www.MyAwesomeWebsiteImBuilding.com]Chrome [Gmail][Chrome Recent web search] | [iTunes] | [Outlook Express] | [Photoshop CS4] | [Dreamweaver CS4] Does anyone know of a tool or hack to prevent Windows 7 from grouping taskbar buttons?

• What should I encrypt in Debian during install?

  - by ianfuture

  I have seen various guides and recommendations on web about how best to do this but nothing that clearly explains the best way and why. So I understand there is a need for part of Debian during install to be un-encrypted on its own partition to allow it to boot. Most info I have seen is call this /boot and set the boot flag. Next I believe the best approach is to create another partition out of all the rest of the disk space, encrypt this, then on top of that create a LVM and then within the LVM create my various partitions , name them , select size, and file system type. Can I include /swap in the encrypted LVM part ? Is this approach sound? If so what are the partitions I should use (this is going to be a minimal server install with a view to install as and when what I need for a dev server)? Finally how does the installer know what to put in each partition I define ? I appreciate there are more than one question but any help and suggestions would be appreciated. If further clarification is needed please mention in the comments . EDIT : 16/3/2010 After Richard Holloways reply I thought it relevant to add this info: The reasons why I want to do this are to explore maximising security on any server install and set up, due to interest in the area of Computer Security and Forensics. Also I am trying to peform the task as if it being performed in an enterprise situation. On a technical matter, once set up and configured with minimal packages and ssh this server will not physically be easy to access so I will only be entering via ssh. (Yes I know why encrypt something no one will ever be able to get their hands on? Because I can and I want to is the simple answer, but see above too).

• How do I setup a secondary incoming mail server?

  - by abrahamvegh

  I currently have a server running Debian 6, with postfix and dovecot handling email. This server hosts email for a number of domains and users, so I use MySQL as my backing store for users and forwardings and everything related. Currently, this server is the only server listed in an MX record for all of the domains it serves. I would like to create a secondary server that would be listed in the DNS with a lower priority (e.g. current primary server is priority 5, secondary would be priority 10), so that in the event that I need to reboot the primary server, or otherwise make it unavailable, the secondary server would receive email, and hold it until the primary server came back up, at which point it would deliver any held email to the primary server. I do not need the secondary server to function as a backup sending server. Users would never need to see the secondary server, they would simply not lose incoming emails if the primary server is down, and they would be unable to send or receive until the primary came back up. How would I go about doing this? I would like to use the same software if they can handle this task, because I’m already familiar with managing them.

• How to track things that SHOULD happen, but might not have

  - by Kamiel Wanrooij

  I am running into a couple of issues with some applications we've deployed and maintain. I have the feeling we have approached this with some anti-patterns up to now, but I would like to see how to make this more flexible and stable. In one situation, we have a server at a client which pushes data to us to parse every night (yes, Windows Task Scheduler). This is highly unstable however, so once every month this doesn't happen because of reasons out of our control. This heavily impacts our business since we run with stale data in that situation. In another scenario we have a lot of background job processes that should be running. We already keep them up using bluepill ( http://www.github.com/arya/bluepill ) but obviously restarts happen, both automatically and manually, and people forget things or systems mess up. What I would like to track is events that should occur or should be available. Like the existence of a process, the execution of a program, or the creation/age of a file, and track it when they don't happen or exist. We develop most things in Ruby on Rails, use NewRelic, Bluepill and Munin, and run on Ubuntu. I've been toying around with counting ps aux | grep processname | wc -l in Munin scripts, or capturing the age of a file and raising alerts over 24-26 hours, stuff like that. Is there better tooling to track things that should happen, and raise alerts if they don't? P.S. I know some things are suboptimal, like manually having to define bluepill for applications and then forgetting to do so. The same goes for the push based approach of the first application, a dedicated daemon that manages that on the client side that we control and can track its connection to us might be a much better solution.

• How to backup virtual machines on a standalone ESXi host?

  - by Massimo

  Standalone ESXi (4.1) host without any vCenter Server. How to backup virtual machines as quickly and storage-friendly as possible? I know I can access the ESXi console and use the standard Unix cp command, but this has the downfall of copying the whole VMDK files, not only their actually used space; so, for a 30-GB VMDK of which only 1 GB is used, the backup would take 30 full GBs of space, and time accordingly. And yes, I know about thin-provisioned virtual disks, but they tend to behave very badly when physically copied, and/or to blow up to their full provisioned size; also, they are not recommended for actual VM performance. It is ok for me to shut down the VMs before backing them up (i.e. I don't need "live" backups); but I need a way to copy them around efficiently; and yes, a way to automate shutdown/startup when taking a backup would also help. I only have ESXi; no Service Console, no vCenter Server... what's the best way to handle this task? Also, what about restores?

• Distributing Microsoft Office Template or Macro over the network

  - by zfranciscus

  We have around 400 users who use Word and we want to make their life easier by distributing templates and macros over the network. The easiest way to do this of course to setup a shared network folder and let them get the appropriate templates and macros. Of course, each user has to know where to copy these files to in their local PC, and we have to rely on constant email communication to let them know for newer version of the macro and templates. The next alternative is to ask them to configure Word to point to these network folder. But of course any disruption to the network means disruption to their work. We are thinking to setup a synchronization mechanism that downloads new templates to their local machine. We are also thinking to make this sync tool to prompt users that it will download new templates - you know just to give them visibility that they are receiving changes. We are wondering what is the best approach that people usually use in their workplaces ? Are there any specific tool that can make this task easier ?

• Arduino IDE "launch 4j" error

  - by John

  I have a computer running Windows XP. I am trying to run the Arduino IDE 0022. I double-click on arduino.exe, it waits about 30 seconds on the load up title screen, and then it gives me this error: Launch 4j: an error occurred while starting the application My only choice is to click "OK"; the error goes away, and the Arduino IDE closes. If I try to delete the Arduino files (to try overwriting with some different files), I get an error that doesn't allow me to do so: Cannot delete awt.dll: Access denied Make sure the disk is not full or write protected and that the file is not currently in use. The only way to delete the file is by restarting the computer. So something must still be trying to run after that first error. I have noticed in Task Manager that some Java programs are still running: javaw.exe (3 processes) I think this is a problem with Java, but I checked and updated all of my Java software and it is all up to date. I have looked on other forums for this issue and none of them seemed to help. From the forums I have tried: Different Arduino IDE versions Updating Java Opening arduino.exe as Administrator Nothing has worked. Anyone have any suggestions?

• screen scraper templates for various websites

  - by intuited

  I'm looking specifically for a convenient way to locally archive posts from this and other similar sites. I'd like to separate the question itself from the answers, or maybe crop the question and store it, keeping the page title. Obviously I don't need to store the menu or the various other site interface chrome. The best way to do this would seem to be to associate an XSLT template with a match on the URL and use that template to pull the various relevant informations and format them. My two-part question: Is there a tool specifically built for this task? I.E. something that takes a URL and checks it against a map of path-matching expressions to templates, and outputs the result of applying the template to that resource? xmlto seems to be most of the way there, and could probably just be called from a script that does the pattern-matching, but something already integrated would be more convenient. Is such a URL_pattern-to-XSLT_template map publicly available somewhere? Question 2.5: Is it legal to do this with sites like this one that have public licenses on their content?

• How do you permanently disable the 'This Connection is Untrusted' page on Firefox

  - by TheIronChef9

  I'm going insane. Can someone please help me to COMPLETELY DISABLE the 'This Connection is Untrusted' page on Firefox. Facts: I am running Firefox 23.0 on an Ubuntu machine (downloaded and installed ubuntu today) It is a work computer and I have to use my employer's proxy While visiting Webpages/webapps like Gmail or Google brings up the 'This Connection is Untrusted' page and I have to go through the whole tedious task of selecting 'I understand the Risks' and add Exceptions, etc. etc. The fact is, I don't care about the risks. I would rather this computer melt into the ground than have to see that page ever again. I want to dance naked in untrusted pages and not give a damn about the consequences. I just never want to see that page again. Ever. For some sites (eg. wikipedia), the css doesn't load and I end up seeing them in plain text. As a result these sites are completely useless. Wasted hours trying to solve this for stackoverflow.com. These issues happen on the Firefox on my Windows XP machine as well (also using the same proxy). I don't want to export/import certificates or create exceptions for every site that shows this bloody page. I just want this page gone. I don't want Firefox to tell me what's safe and what's not. Also, my system time and date are correct. I've also tried the lies on this page too with no good results. Edit: I've also tried the whole going into the Advance-Certificates-validation setup page and unchecked 'Use the Online Certificate Status Protocol (OCSP) to confirm the current validity of certificates' checkbox. Nothing happened even after restarting firefox or rebooting. I need help. Thanks.

• Exchange 2010: Send emails via STMP with custom From address to outside the domain

  - by marsze

  The requirement(s): (1) Connect to Exchange via STMP and (2) basic authentication and send emails with a (3) custom From address to (4) recipients outside the domain. I was able to get (1) - (3) working. I created a dedicated receive connector for this task and configured it like this: Permissions: ms-Exch-SMTP-Accept-Any-Recipient (for authenticated users) ms-Exch-SMTP-Accept-Authoritative-Domain-Sender (for authenticated users) ms-Exch-SMTP-Accept-Any-Sender (for authenticated users) Authentication: TLS Basic Authentication (without TLS) Exchange Server Authentication However, I'm still struggeling with (4): I can send with "fake" From addresses to recipients inside the domain. Also, I can send with the original From address to recipients outside the domain. Can you tell me what I'm missing, to configure Exchange to send emails with changed From addresses to recipients outside the domain? (Or is this even possible at all?) Thanks. UPDATE I have to correct myself: it seems to be working after all. There must be some issue with the mailbox I used for testing. It turned out it's working with other external mailboxes. However, I still have no idea what was different there... Anyways, you can take this as a documentation on how to configure Exchange in such a way ;)

• Is there a way to use VirtualBox without using it's resource registry?

  - by Catskul

  Summary VirtualBox seems to want everything to be "registered" which makes it much more annoying to work with on the command line. I'm attempting to create an automated script which will create, move, start, stop, and destroy virtual machines and virtual disks. Requiring registration will complicate the task for the following reasons. leaves state information around that can cause unpredicted edgecases causing scripts to fail. creates potential name space collisions for multiple process creating VMs with the same name moving/copying resources on the same machine is more complicated because references in the registry need to be updated copying resources (disk + vm combination) to another machine require reconfiguration once they reach their target machine, and require the transfer of extra meta data to do the reconfiguration. If something unexpectedly fails, and an unregister thus fails to happen, left over configuration information can cause problems in subsequent runs. Use Case My specific use case is for a continuous integration server which creates and destroys VMs and Disk images potentially with the same name, and would require more logic to deal with the registry's statefulness. Imaginary Example It seems that I should just be able to for example (using some imaginary and/or incorrect commands): mkdir foobar customdiskimg_script ./foo/foo.vdi vboxmanage createvm --name "foo" --ostype Linux --basefolder ./foo/foo.xml vboxmanage storagectl ./foo/foo.xml --name foo --add ide vboxmanage storageattach --storagectl foo --medium ./foo/foo.vdi ./foo/foo.xml vboxmanage startvm ./foo/foo.xml TLDR Is there a way to use virtualbox without "registering" harddisks and VMs?

• Win 7 64 with 8 gig of ram, getting running low on memory errors.

  - by John

  I have a new Dell laptop running Win7 64 with 8 meg of ram. If I leave the system running overnight I start getting low memory errors the next day. Looking at task manager it shows 6.27 gig used but looking at the processes list the totals don't show nearly that much. I am showing all processes from all users. I have also looked at the processes with PRocess Explorer and see the same results. Using resource monitor I see 4165 MB in Use, 2328 MB Modified and 1352MB Standby with only about 345 MB free. These numbers don't seem to add up to what I have running. I have Visual Studio 2010 running along with a number of IE8 sessions. I have run the same set of apps with XP SP2 32 bit with 4 gig of memory and never had this sort of problem. What is Modified memory? What is Standby memory? Any suggestions on what might be the issue and what might be a fix? TIA J

• Did Adobe Photoshop just killed my Graphics Card for good?

  - by user6004

  I was working with Adobe Photoshop, just some regular work, when I came to edit a PSD file and change the text of some layer, when all of a sudden the PC froze. No mouse, screen is frozen, keyboard strokes aren't getting me anything, no Task Manager, nada. So I rebooted my PC, and then something quite terrifying appeared before my eyes. It was not the Checkdisk utility that was launched, that made me terrified (by the way, that reboot damaged the partition table of an external HDD that was connected at the time to my PC, but that's another story). It was the screen itself. Please have a look. So after Checkdisk finished and Windows loaded, I noticed that the resolution was not right. Instead of 1440x900 which I had set, it was 1280x1024. When I went to change it back, I had no option to change back to my old resolution, and has only 3 other general resolution properties, as if my Video Card (GeForce 8800 GTS btw) was not recognized. And what do you know, in the Device Manager it appeared with an exclamation mark. Inside the hardware, it said this: Windows has stopped this device because it has reported problems. (Code 43) Uninstalling the drivers, downloading the newest drivers from NVIDIA and installing them did not work. It always comes back to this. So, do you have any advice before I go out and buy a new graphics card? I thought this was the only option left, but maybe the experts at Super User can help me out. By the way, the dotted screen appears after every reboot, and I see the dots when the ASUS Motherboard screen shows up at boot. Thanks in advance.

  - by Jim Fell

  Hello. I'm running a machine with Windows XP Professional 64-bit. Every so often, it will freeze for no apparent reason. That is, everything stops responding, except the mouse. I can move the mouse around, but I can't click on anything. Keyboard input is also not accepted/received when this problem occurs. The three-finger salute fails to bring up the Task Manager. Even pressing the power button on my computer fails to shut it down. The only way out of this that I have found is to hard-reboot the machine (i.e. pull power or hold power button in for 10 seconds). This problem was occurring on the system when it had all its updates and after a fresh install when not everthing was quite yet updated. I've run the Scandisk utility and the latest version Memtest86 that supports 64-bit architecture; neither found any errors. The last time this happened was on a fresh install of Windows. Only Nero Essentials, Avast antivirus (disabled), Firefox, and Spybot were installed. I was not running Nero, Firefox, or Spybot at the time, and Avast was disabled, so I'm pretty certain this is a Windows issue. Is anybody familiar with this problem or have any pointers? Thanks.

• Audit file removal (auditctl)

  - by user1513039

  For some reason, some script or program is removing a pid file for the service on the linux server (centos5.4 / 2.6.18-308.4.1.el5xen). I suspect a faulty cron script, but manual investigation did not lead me to it. And i still want to track it down. Have been using auditctl rule: auditctl -w /var/run/some_service.pid -p w Which helped me to see something, but not quite exactly what i wanted: type=PATH msg=audit(11/12/2013 09:07:43.199:432577) : item=1 name=/var/run/some_service.pid inode=12419227 dev=fd:00 mode=file,644 ouid=root ogid=root rdev=00:00 type=SYSCALL msg=audit(11/12/2013 09:07:43.199:432577) : arch=x86_64 syscall=unlink success=yes exit=0 a0=7fff7dd46dd0 a1=1 a2=2 a3=127feb90 items=2 ppid=3454 pid=6227 auid=root uid=root gid=root euid=root suid=root fsuid=root egid=root sgid=root fsgid=root tty=pts0 ses=38138 comm=rm exe=/bin/rm key=(null) Problem here is that i see ppid of the script that removed the file, but at the analysis time the (p)pids are already invalid as probably scripts/programs have been shutdown. Imagine a cron script deleting the file. So i need some way to expand/add audit rule(s) to be able to trace the parents of the /bin/rm at the time of removal. I have been thinking to add some rule to monitor all process creation, something like: auditctl -a task,always But this happen to be very resource intensive. So i need help or advice how to combine these rules, or how to expand any of the rules to help track the script/program. Thanks.

• Good support to multiple desktops AND multiple monitors in Linux (Ubuntu)?

  - by Somebody still uses you MS-DOS

  I'm starting to have A LOT of opened windows in my machine. Sometimes within a project, I have e-mail/task management/personal e-mail/twitter, and a lot of different opened applications/terminal in my Linux environment. Nowadays I have 4 worspaces: Corporate management (e-mail) and corporate messenger; Work (Documents, Requisites) Dev (Development, All gVim windows, terminal and Firefox for development) Personal (Personal stuff: personal e-mail, delicious, twitter and so on) Sometimes it would be interesting to have different workspaces to projects instead of this configuration I have nowadays that are classes of work (bad name, I know, but I think you got the idea). I'm starting to think about using two monitors: one with Corporate Management, Work and Personal. The second monitor is only the development state: each workspace here is about a project being worked on instead of groups of works like before. A workspace may be implementing different classes for example. My question is: I just want to change to a second monitor using the mouse. I want to still be able to change workspaces in the same monitor using keyboard shortcuts. The keyboard shortcuts wouldn't change monitors, just worskpaces on the same monitor. Does Linux (Ubuntu 10.04 Lucid Lynx) support this envisioned setup? If so, how?
