• A really unique case of Load Balancing

  - by Shamshun

  I have an internet connection which has limited up/down bandwidth per IP address. What I want to do is to get multiple IP addresses on a "single" LAN interface, and use a load balancer to distribute traffic through them. I was successful at getting 100 ip addresses on a single interface. my problem is that Linux and Windows use the first ip address of an interface by default, so my bandwidth is not increased. I would appreciate if someone tells me what Load Balancing software has the ability to distribute load between multiple IPs on a single interface. I have tried to do so on both Win7 and Backtrack-LinuxR2

• How do I do advanced searches in Mac OS X?

  - by Philip

  I don't get it. I just want to do simple searches that work. When I type part of a filename, I want to see all the files that have that part of the filename. I know how to do this in terminal, but it takes time to open and then to track down the file once it finds it. Is there a way to do this from the Finder? I want to be able to do *.doc and get all my docs, or hello*.txt and find all filenames of that form. Am I missing something obvious? Bonus points if you can tell me how to do boolean searches from the Finder (filename:hello*.txt AND modified:4days) or something. OSX Snow Leopard. Thanks!

• Can't ping my computer - "Transmit failed. General failure."

  - by Vaccano

  I am having an issue with my computer. My IIS services are not working. I have narrowed it down to the fact that my computer cannot find itself via its name. I try pinging my computer by its name and I get this: C:\Users\18773ping MyComputerNameHere Pinging MyComputerNameHere [::1] with 32 bytes of data: PING: transmit failed. General failure. PING: transmit failed. General failure. PING: transmit failed. General failure. PING: transmit failed. General failure. Ping statistics for ::1: Packets: Sent = 4, Received = 0, Lost = 4 (100% loss), I tried having someone else ping my machine and it works fine for them. Any ideas?

• Weird noise coming out on Windows 7 when harddisk activity at peak?

  - by Curious Apprentice

  I'm having a very strange problem. I'm hearing a "choooooooooo kkkrrr" sound (Its not like the normal sound speakers make when powered on) all the time. When there is more Hard Disk r/w activity the sound increases and as HDD r/w activity slows down so the sound. I have two other OS installed on my system. I have tested, it only happens when I'm on Windows 7. I have no clue what the hell is happening !? Any help would be greatly appreciated. Here's the sample of noise: http://www.ziddu.com/download/20852917/noise.mp3.html

• mirror sql server 2008 to AWS instance from our datacenter?

  - by Alex

  We are currenlty running on hosted pos system locally and would like to mirror to AWS. We are new to AWS and would like to know the most cost effective way to do this? We have 2 DB and 2 web servers right now in one cabinet in CA. One tape drive, one firewall, one SNA. We are thinking to replicate our system in AWS (using sql server 2008) and just mirror both systems and use a witness server between them to keep the data in sync? The goal is, if CA datacenter goes down, AWS keeps running. User see no downtime. All data is synced. Is anyone doing something similar? Would this be practical to just use AWS in this fashion? Thanks

• Help me diagnose Windows 7 pc issue

  - by lkm

  I have a dell pc running windows 7 with the intel i3 processor. Whenever I restart the computer, the os crawls. For example, I move the mouse and then I see it move on the screen 10 seconds later...everything runs slowly. This happens only on a restart (its fine when I turn it on after it has been shut down). Any ideas what is causing this (I haven't installed any new software since buying it). Does it sound like a hardware or software issue? Thanks

• How to make a backup VPN server?

  - by akalenuk

  I have a small VPN network with a bunch of clients working mostly with each other and a VPN server. Everything works fine, except, obviously I can't shut VPN server down without breaking the network. I have a spare machine, which worked as an VPN server for the same network before so it is signed with the same SA as the first one and basically configured just the same as the first one. Technically I can make my clients work with it with little adjustment (by setting remote in etc/openpvn/clientx.conf), but it would be great make this switch automated. So basically I want two VPN servers running in the same network to work completely interchangeable without clients even knowing this. Can I do this with VPN or should I dig deeper into physical network layer?

• Oracle (xe) 10 vs 11 . Have I lost the SQL tuning pages ? Am I going out of my mind?

  - by Richard Green

  Ok .. so perhaps the title needs calming down a bit, but basically I am after the xe 11g equivalent of the pages that you can see here : http://docs.oracle.com/cd/B25329_01/doc/admin.102/b25107/getstart.htm#BABHJAGE whcih you can then navigate to stuff like "top 50 queries" and "longest running queries" etc etc. For the life of me, I can't find that on the most recent xe edition. Please can someone direct me to where I might find these very useful admin pages ! Or was I imagining it all along :-/ Edit: These are the pages I am after: http://docs.oracle.com/cd/B25329_01/doc/admin.102/b25107/monitoring.htm

• Resize2fs at 81h and counting

  - by Adam

  Setup: 12x 1TB drives in a RAID6 (MDADM) crypt-setup running ontop of MDADM LVM running on the crypted drives EXT4 on the LVM Background: I added a new drive to the RAID (increasing from 11 to 12 drives), and 'bubbled' up through the layers (MDADM, etc...) to reizing the ext4 partition. This machine is used as a centralized repository for photography and as a backup server (for both Windows and Mac machines) so bringing it down to add the drive and wait for the resizing and everything wasn't really an option. So I started the resize operation several days ago. HTOP is reporting the resize2fs operation as running for 81h now. DMESG and syslog are both clear, and the drives are still accessable. The resize command reports it's started an online resize of the partition, so the process IS running, and it is burning through 100% of one of my cores. Question: Is it normal for the operation to take this long or has something gone horribly wrong? Where would I start looking for signs of trouble?

• Multiple Monitors on One Screen

  - by Hulihan Applications

  Does anyone know of any software/hardware configuration that will allow you to preview/view the contents multiple monitors on one monitor? Let's pretend: I have two monitors hooked up to one pc, Monitor A and Monitor B. The monitors are not near each other. I'd like to be able to preview/see what's displaying on Monitor B on Monitor A I haven't been able to find much about this, but I imagine it may not currently be possible to access/emulate video output going out of a video port in software. However, wouldn't it be possible to capture display data generated by the OS kernel or data getting passed down to the display adapter driver?

• Ubuntu - Is there a way to associate keyboard shortcuts to bring a window to front?

  - by Bogdan Piloca

  I am using exactly 3 programs: - a browser - a terminal - a code editor I keep all in fullscreen windows. What I need is to be able to bring any one of them up with a simple keyboard shortcut, like Ctrl+Alt+B for browser, etc. Alt-Tab sucks because I have to stop and see where the selector is. Using 3 workspaces is better but still not ideal - I need to think about where I am and where I need to go. E.g. My browser is on top of my terminal and my code editor is to the right of the terminal. So to move from browser to terminal I use Ctrl+Alt+Down, but to move from code editor to terminal I have to do Ctrl+Alt+Left. Instead I should just do Ctrl+Alt+T for terminal, for example. Thanks!

• strange memory usage pattern on windows server 2008 on login through remote desktop..

  - by headsling

  I'm running Windows Server 2008 Datacenter Service Pack 2 on a VM Ware instance with 10Gb ram allocated. I'm not running IIS or SQL Server. Under 'normal' conditions, the machine uses ~5.5Gb of memory. However, when I login to the server through remote desktop, the memory usage slowly climbs up to 9.8Gb of memory in use. After several minutes the memory slowly creeps back down to the 5.5Gb mark. I've tried killing all the processes associated with my login, on login, barring the taskmanager without success, and I can't see any process that is growing in memory usage when the memory is increasing. I'm assuming this is some system level cache that is growing / shrinking... but why is it doing this?

• Windows domain login to temporary user

  - by amyassin

  We have a Windows domain with about 60 user accounts. Sometimes when a user logs in to his computer (already his account is created and has files there) windows logs him to a temporary user, displaying his name and everything, but without his files and data. This problem is rare and is solved simply by logging out and logging in. I noticed that it occurs at a close timings; they all happen at the same day if they did. My question is why does that happen? I want to trace the problem because it is so annoying when it happens, and I can't find a relative event that may be causing it: no server is down when it happens, no system maintenance or anything. We're running Windows Server 2003 R2 Standard, SP2 in the Domain Controller (and the same for the additional DC). The machines where this problem happened before are running Windows XP and Windows 7.

• Too Much Swapping, even though RAM is 2/3 Empty

  - by indyaah

  I have a VPS with 9GB RAM, 300GB HDD, 3 GB Swap, 7 Cores. The OS is CentOS 5.7 Final. I have postgres9.0 running on my machine, with proper tuning done (at least by book/wiki of PostgreSQL). What happens is most of the times when some complex query run (by complex I mean select with maximum 3 Joins), eventhough 66% of my RAM is unused there is ~99% swapping is happening. Plus it screws up my disk IO which is most of the time reaching ~100% and slows down everything else. (I tend to believe something's wrong with my disk.) I dont understand the reason of this much of swapping happening. Is it because of context switching?? Most of the time my processors are idle, while the IO wait goes upto 30% during pick times. Would appreciate if some can shed some light on it. Thanks.

• Hardware advice for bitmap / openGL image processing server?

  - by pdizz

  I am trying to work out a build for a processing server to handle bitmap processing as well as openGL rendering for chroma-keying images and Photoshop automation. My searches here and on Google have turned up surprisingly few results, and seeing that there aren't tags for bitmap or image processing I take it this is a specialized application. The bitmap processing is very cpu-intensive while the chroma-keying and Photoshop stuff is gpu-intensive. I doubt this is a case of over-optimization as our company batches thousands of images a day (currently on individual workstations) and any saving in processing time and workstation down-time would be beneficial. Does anyone have any experience with this type of processing server? Any special considerations that would go into a build like this or am I over-thinking it?

• Prevent history deletion on Google Chrome

  - by ProstheticHead

  One of the guys I'm in charge of hasn't been pulling his weight. His productivity and quality of workmanship are way down and his computer's been getting malware infections lately. You can see where this is going. I'm generally an easy going guy (and I don't want any trouble but I still have to address this issue). Is there a way to disable browser history deletion on Chrome? I'm hoping this alone will be enough of a deterrent to put things right.

• Entering the user's name in a URL for Chrome through Group Policy

  - by Automate Everything

  I am managing a Windows Server 2008 R2 server, with several Windows 7 machines, and we have recently deployed Google Chrome using Group Policy. We also have a locally hosted intranet for storing procedures, forms, and so on, as well as reports that pull directly from our databases. I am trying to put the user's name in the startup URL for Chrome, so that when they open Chrome at the beginning of the day, it can pull a list of items from the database that contains their username. The report works, and I have it using a drop down right now, but I would like to be able to put their username in the URL as a GET variable instead. Does anybody know how I would go about doing that for Chrome? I tried putting ${user_name} in the URL, and I tried putting %username% in the URL, but that didn't translate to anything. Is there some way to escape it so that it gets translated by the system into a username? Any help would be greatly appreciated.

• All MySQL Databases lost overnight

  - by Iain

  After a call from a customer to say that his website is down, I find that MySQL on our RackSpace Cloud Windows 2008 server was not running. I restarted MySQL but got the 'Access denied for user' error in the browser for all websites with MySQL database. When I look in MySql Server 5.5/data there are no folders other than mysql and performance_schema. It appears all the databases and data have been wiped. Does anyone know what might have happened and where the data has gone? To top that I just found this server is missing from our backup service. ps appears to be after windows update at 4:01 this morning.

• Debian virtual server hangs on reboot, need help debugging

  - by BubuIIC

  I'm admin of a Debian 6 virtual server. I've been trying to diagnose this problem for a while but haven't gotten anything. The server hangs every time I want to reboot it. All services seem to be shutting down, I lose ssh connection. Then nothing. I have to restart it through the hoster's web-interface, which just gives me the options "Normal Boot" and "Rescue System". Normal boot then brings the server back to life. Possibly (probably?) related, the server does not boot into a newer kernel version, it's running 2.6.18 right now, but installed is actually 2.6.32. I don't know whether it hangs on shutdown or on startup, but booting through the web-interface works (except the kernel part). Am I missing something obvious? Where should I start looking? I have no idea how to diagnose the problem.

• Ubuntu works in try out but not when installed, how to fix?

  - by QVaren

  I've got quite a problem with it, perhaps the problem lies with me but I thought I fixed it, I believe the opposite now... Anyhow, I started off with a 64-Bit Windows 7 platform and I wanted something new then the same boring windows, I heard about Ubuntu before but I didn't see a reason to change it. Now I had found my reason, so what did I do was do the installation via an USB, I went "try out before installation" first and it worked perfectly, however... When I installed it, deleted my Window 7 and tried to reboot with my fresh oh-so-clean new OS, it didn't want to load. At a certain point it said to boot up from a bootable option or something like that. Where it came to was that I couldn't load it up. Now, I wanted to switch back to Windows 7 because it didn't work and now I can't switch back because my harddrive switched modus because of Linux files (From NTFS to 4ex or something, I forgot). I'm currently typing this in the try out version of Ubuntu since I can't switch back to either Windows 7 or to the installed version of Ubuntu. So, my question follows: Can I fix it by keeping Ubuntu? Because I like Ubuntu. Also a side note: I'm a total noob when it comes down to this sort of things.

• Is there any way a user can view or copy GUI controls' properties at runtime?

  - by jqngrc

  Here are two examples of what I mean: I am sure you all too have experienced this frustration before. A dialog box opens that displays only part of a long string (e.g. a file path), but won't allow you to select the text so you can see the full string. Neither it will resize upon window resizing—which is unusual among Windows dialog boxes. The text is hidden, period. Copying a very long drop-down list control contents to a text file. Do you know any way to solve these problems?

• Access to certain files but not others

  - by ADW

  Hoping someone can help me as I have, thus far, been unable to solve the issue. I am running a media center utilizing Ubuntu 12.04. I was initially successful accessing media files from the desktop running Ubuntu via my Windows 7 laptop and Roku device. I started backing up a new batch of DVD's I had (into MKV files, like everything else in my media folders) and noticed I cannot access the new files from either the Roku or the laptop. I have not changed any settings in the media folder and verified the shared permissions. The parent folder (Media) is shared (with permission flow-down) while the subfolders (Movies, TV Shows, Music) are not. I have changed the permissions on this to include shared when the access problem arose but with no success. I can only access the original files uploaded an not new files added. Any suggestions??? Thanks in advance for any and all help.

• Security against IP spoofing [on hold]

  - by user1369975

  I am pursuing a college project, in which I am running three fake services on three ports to protect the main service (say running at port 80). The concept is that if the user is malicious, he'll try to bring the services down and access the fake services. These ports adopt a blocking process of a connection request and record the IP and port of the client. These are logged and aren't granted access on service on port 80. But what to do if the client spoofs his IP? How can I modify my system?

• Include new rows in autofilter range

  - by user9645

  I am working with an excel 2007 worksheet that has the "filter" applied so that each column heading has a pull-down menu for sorting. When I add new rows to the end of the table by cut-n-paste from the last row, these new rows are not included in the sorting. I can't seem to get the newly added rows to be included in the filter range. I tried un-selecting and re-selecting the "filter" button and also tried the "reapply" button. The "clear" button is always greyed out. I can't seem to find any relevant help for this online anywhere. Not sure if it matters, but the heading row and the first column are set to be "sticky" (they don't scroll with the rest of the table.)

• Outlook 2007 starts with minimized window

  - by astro46

  Outlook 2007, starts at boot, minimized: suddenly, as of 2 weeks ago, when I click on the taskbar icon (Outlook already started but minimized) what opens on screen is a tiny "window" the size of the close-minimize-restore buttons. I then have to move it down the screen, and drag the borders to bring it to full size, or, sometimes, clicking on the restore button maximizes the tiny window: then, for days, it starts either the same way or in some other small size, not the same as I left it. I would appreciate suggestions on how to repair this particular example of Outlook not remembering its setting? win7, 64 bit. outlook 2007 32 bit
