  • Which Ubuntu-like Linux OSs work well on a flash drive?

    - by Evan Kroske
    I want a Linux OS that I can load on a flash drive, but I don't want to relearn an entire operating system. I want to know which tiny Linux installations are most like Ubuntu. For example, I'd like to use the apt-get package manager, the Gedit text editor, and the bash shell. I'd like to use something that's already popular, stable, and highly compatible, but it needs to fit comfortably in one gig of my four-gig flash drive (just the essentials; I'll use the remaining three gigs to store installed programs and files). I have no preference for window managers; I just want something small and fast that works like Ubuntu. What is the most popular Ubuntu-like OS that can be easily run on a thumb drive? Edit: I'm not sure I understand how this works. I don't to use a USB drive as a LiveCD; I want to plug in a USB stick and use the computer as if it was my own. In other words, I want to be able to install programs on the drive on one computer and use them on another. Do any of these OSs let me do that? Please forgive my ignorance.

  • DPMS, keep screen off when lid shut

    - by Evan Teran
    I have a laptop running linux. In my xorg configuration, I have DPMS setup so that the screen automatically turns off during several events. In addition to that I have to the following script tied to ACPI lid open/close events: #!/bin/sh for i in $(pidof X); do CMD=$(ps --no-heading $i) XAUTH="$(echo $CMD | sed -n 's/.*-auth \(.*\)/\1/p')" DISPLAY="$(echo $CMD | sed -n 's/.* \(:[0-9]\) .*/\1/p')" # turn the display off or back on export XAUTHORITY=$XAUTH /usr/bin/xset -display $DISPLAY dpms force $1 done Basically, this script takes one parameter ("on" or "off") then iterates through all of my running X sessions and either turns on or turns off the monitor. Here's my issue. When I close the lid of the laptop, the screen goes off as expected, but if a mouse event occurs (like if something bumps into the table...) then the screen turns back on even though it is closed (I can see the light through the side of the laptop). Is there a way to prevent the screen from turning on during a mouse event if the lid is closed?

  • Thinking about buying a LG 30" monitor

    - by evan
    I'd love to get http://www.newegg.com/Product/Product.aspx?Item=N82E16824005115 but I'm wondering if I should hold out until more LED monitors are on the market. I love really like the brightness of the 27" imac monitor and the above monitor is only rated at 5 cd/m2 less than that monitor, but wouldn't a back lit monitor appear to be much brighter than an LCD monitor? Does anyone know how the above monitor compares to the 27" imac monitor? Why are Apple monitors in general so much more expensive than other monitors - just the brand name? I must be confused about how to read the specs? Thanks in advance for your input!

  • NFS or GFS for LVS 10 Server Setup

    - by Michael Robinson
    Currently we have a 10 servers LVS hosting setup. The people we hired to set it up did not anything about GFS which was our preferred Central Storage File System Solution. As we have tight time constraint, we just told them to use whatever they were familiar with which is NFS. I have since done some research and it seems that NFS is not ideal for the type of high traffic site we are hoping to build. I couldn't find much info online about the signaficance differences between the 2. As we to setup all servers again right now, should we stick with NFS or find someone who knows how to setup GFS amd go with that. We need a setup that is highly reliable and scalable as we intend. As after initial setup is done, we expect high increases in traffic and load.

  • Winlogon.exe causes C++ runtime error

    - by Evan
    Recently I've become unable to log into my Dell Precision M2400. It uses the Dell Controlpoint login GUI instead of the typical windows one, and has now started giving me a runtime error on winlogon.exe that ends with a c000021a BSOD. I have tried running through safe mode and a restore to the last known good setting with no success. Unfortunately by BIOS password is locked and the one IT guy with the password is on vacation and unreachable until after I leave for a business trip. Is there anyway to bypass the Dell logon screen and get to the default windows one? Thanks.

  • Set default wireless adapter

    - by Evan Kroske
    I just acquired a Wi-Fire long-range wi-fi adapter, and I would like to test it with my Ubuntu desktop computer. However, my machine defaults to using a built-in wireless card. How can I set my new wireless adapter as the default wireless connection? How can I disable my internal wireless card (without opening my computer case)?

  • High disk I/O - jbd2/sda2-8 process

    - by Evan Hamlet
    I have run a file server on a CentOS 5.8 final server. My only concern at the moment is what appears to be intermittent but continuous high disk I/O activity causing a general slowdown because of jbd2/sda2-8 process. jbd2/sda2-8 is making use of /dev/sda2, which is the 2nd partition of the first harddrive (IE: root partition). More info: using "iotop" the culprit appears to be "jbd2/sda1-8" making writes every second, which appears to be a kernel process associated with journaling on the ext4 filesystem, if my googling around is correct. I see "jbd2/sda2-8" appearing here every now and then, but certainly not every 3 seconds.. when idle, it appears about 1 or 2 times per minute. When I'm using the system, it appears more frequently. ATOP results: http://grabilla.com/02b14-8022db2e-4eb9-4f10-8e10-d65c49ad7530.png IOTOP results: http://grabilla.com/02b14-cf74b25d-4063-4447-9210-7d1b9b70e25b.png HTOP results: grabilla. com/02b14-ad8cad0e-89b0-46d3-849d-4fd515c1e690.png jbd2/sda2-8 is the processes I see with iotop making writes on disk even though it's not in use at all. Does someone has any idea how could I solve the high disk usage caused jbd2/sda2-8 process?

  • Installing WinPcap on Windows 8

    - by Dave Robinson
    I know there has been lots of discussion already on installing WinPcap on Windows 8. I'm running the RTM version. I was able to install WinPcap without a hitch by using the Windows 7 compatibility mode. Since then, I've noticed that WinPcap has stopped running and is actually no longer even installed. I tried installing it again, but now it continues to tell me that WinPcap does not work with my version of Windows. Compatibility modes and admin privileges make no difference. The only thing I remember doing to my system was installed 900MBs of Windows Updates. Does anyone have any ideas about what I might do to get WinPcap installed? I've already ensured that the compatibility mode settings I changed were in effect for all users. I've already ensured that "run this program as an administrator" is checked on the compatibility tab for all users. I've also tried installing WinPcap 4.1.2 and 4.1.1. No success with either.

  • What do the numbers on Western Digital drives mean?

    - by Evan Carroll
    There are numerous numbers on a Western Digital drive, MDL (presumably model, ex WD5000BEKT-00KA9T0) -- not sure what the 99KA9T0 is. WWN (ex 50014EE25AC8C945) DCM (ex HBNTJBBB) LBA (ex 976773168) R/N (ex 77174) Then there are three numbers on the back of the PCB on a sticker White Sticker Left: 2061-771714-002 AC White Sticker Right: XT BD34 T7KQ 8 0002270 White Sticker far-Right: 272 Then there is one number printed on the PCB, REV P1 2060-771714-002 Then there is one number (or three) on the spindle, 71206-T8Y-03 9X0X22MF 32H Does anyone know what these numbers mean?

  • fedora liveUSB fails, drops to debug shell

    - by evan
    Trying to install Fedora 15 via a live USB made with unetbootin. I get to the unetbootin boot menu, select Fedora-15-x86_64-Live-Desktop.is, I get to this screen, then it drops into a debug shell with the message sh: can't access tty: job control turned off. The last message is dmseg is dracut Warning: No root device "live:/dev/disk/by-label/Fedora-15-Beta-x86_64-Live-Desktop.is" found. Seems to be the same problem detailed here. Tried to try nk1eto's solution but there is no by-label directory in /dev/disk. There's by-id, by-path and by-uuid.

  • VirtualBox serial port, limit of two?

    - by Evan Carroll
    Using VirtualBox, Is there a limit of two serial ports per VM? I'm currently engaging in a task that requires more than two, but less than or equal to four ports. I'm at a loss of what to do to get COM3 and COM4 up? How do I do it if the Virtual Box GUI doesn't currently support more than two serial host devices? Can I configure them external to the GUI? Is there a hard-cap on two devices? And, if so, for the love of god, please entertain me with the reasoning? I know Windows and Linux don't impose such a limit, it would seem awkward to impose it in virtualization layer. This is for cheap dial-in project with proprietary Windows tools. I'm using a Quatech serial multiport adapter to provide the ports to multimodems.

  • How Often Do Windows Servers Need to be Restarted?

    - by Evan
    A little background: We have several Windows servers (2003, 2008) for our department. We're a division of IT so we manage our own servers. Of the four of us here I'm the only one with a slight amount of IT knowledge. (Note the "slight amount".) My boss says the servers need to be restarted at least weekly. I disagree. Our IT Department says that because she restarts them constantly that's the reason why our hard drives fail and power supplies go out on them. (That's happened to a few of our servers a couple times over the last four years, and very recently.) So the question is: How often does everyone restart their Windows servers? Is there an industry standard or recommendation? Is our IT department correct in saying that because we re-start that's why we're having hardware issues? (I need a reason if I'm going to change her mind!)

  • Using public interfaces on a server connected through a GRE tunnel

    - by Evan
    I'm pretty new to networking so please forgive any terminology mistakes. I have 2 servers connected with a GRE tunnel. Server1 (10.0.0.1) ---- Server2 (10.0.0.2) I want to be able to bind to the public IPs on Server2 using Server1. To do this, I setup virtual interfaces with Server2's public IPs on Server1 and then used routing rules on Server1 to route the packets through the GRE tunnel. On Server1: ip rule add from [Server2's first public IP] table gre ip rule add from [Server2's second public IP] table gre ip route add default via 10.0.0.2 dev gre1 table gre This works great and I can see the packets arriving via GRE on Server2. I can see the packet exiting the tunnel on Server2's gre1 device as shown: From Server1: ping -I [Server2's public ip] google.com tcpdump from Server2's GRE tunnel device: 12:07:17.029160 IP (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto ICMP (1), length 84) [Server2's public ip] > 74.125.225.38: ICMP echo request, id 6378, seq 50, length 64 This is exactly the packet I want. However, I'm not seeing it go out at all on eth0:0 (where Server2's public IP is bound to). I've tried to use routing rules to get packets coming from Server2's public IP (which would be coming out of dev gre1) to go through dev eth0 on the public default gateway and that doesn't work either. I'm at a loss, thank you to anyone who can help.

  • Add 802.11n to existing 802.11g environment

    - by Andrew Robinson
    I have a small home network that is currently running 802.11g. Two computers that are capable of 802.11n and two devices (a BlackBerry and a Skype phone) that are limited to 802.11g. I have a few neighbors running 802.11g but their signals are very weak. How big an impact will the two G devices have on N speeds? Will they pull the whole network back down to G? These two devices are hardly ever used where as the other N devices are heavily used. If I add an N router to the network (instead of replacing the G) and set my existing G router to use channel 1 with 20MHz bandwidth and then set the N router to use 6 & 11 for 40MHz will I eliminate the overlap and allow for full speed on both networks?

  • SQL Server 2005 SP3 Express Backups Incredibly Slow

    - by Adam Robinson
    I'm attempting to troubleshoot an issue with one of our customers who's using SQL Server 2005 SP3 Express to house their application data. The automatic backups that we perform when upgrading our application are timing out after 30 minutes, and I've been sitting and watching the backup take place in SSMS for about 20 minutes now and it's only gotten to 30%. The database is only slightly over 1GB, so I'm baffled as to what could be causing this sort of horrible performance. The machine is a 1.87GHz Xeon with 3GB of RAM running Windows Server 2003 R2. While that's hardly a powerful box, this seems ridiculous. Does anyone have any idea why these backups could be taking so long and, more importantly, how I can do something about it?

  • Possible boot conflict?

    - by Evan Kroske
    I was installing Ubuntu on a computer on which Windows XP was already installed. The computer has multiple hard drive bays, so I decided to remove the XP HDD and install Ubuntu on a blank HDD when it was the only HDD in the system. Unfortunately, if I now try to boot Ubuntu with the Windows XP drive in the second slot, nothing will boot. However, if Windows XP is in the first slot, it will boot fine. Can anybody explain why this happens? When I was checking out the BIOS to see if something was messed up, I discovered that when Ubuntu is in the first slot, the BIOS doesn't recognize any HDDs. However, if XP is in the first slot, the BIOS recognizes both drives. Any hypotheses about why this happens? Edit: Here's the setup. I have an old server with seven SCSI HDD slots. I have five identical 68 Gb SCSI drives, but I can keep only two plugged in. XP is still installed on the first drive, but I reinstalled Ubuntu on the second drive and had Grub overwrite the XP bootloader on the first drive. Now, the setup works fine, and I can use Grub to load either XP or Ubuntu. However, if I plug in another identical blank HDD in the third slot, the computer recognizes only the XP drive and doesn't boot. Grub starts to load, then gives me a "disk not found" error. Running ls from the grub rescue prompt only shows one drive with two partitions. I guess this is a BIOS problem, but I'd still like to know what triggers it. What about a blank drive could cause the BIOS to freak out?

  • QuickTime X incorrect aspect ratio for H.264 video

    - by Adam Robinson
    I'm running Snow Leopard and have a serious issue with QuickTime X. I have a Samsung HMX-H100N/XAA camcorder that records H.264 video in either 720p or 1080i. In either of these resolutions, QuickTime X (and, by extension, all QuickTime-associated applications like FCP, iMovie, etc.) displays an incorrect aspect ratio for all video produced by this camcorder. For example, 720p video is reported as being 1280x720 in the movie inspector (which is normal), but the displayed size is always at an aspect ratio of something like 63:20 (never heard of such a ratio) with sizes like 1700x539. If I open the video in QuickTime 7 player on the same computer, it is displayed correctly. If I process the video through something like MPEG Streamclip to transcode it, it displays correctly. As it stands right now I have to transcode all of my video in order to use it in any iLive (or other QT-based application) unless I want it to look ridiculous. I've tried installing Perian, but that seemed to have no effect.

  • trying to figure out how to bridge two virtual networks together and in turn bridge that to the internet for a virtual inline IDS/IPS system

    - by Tony robinson
    I'm trying to figure out how to bridge two vmware (server or workstation, workstation) or virtualbox networks together with a linux IDS/IPS system transparently inline between both the virtual networks. How do I accomplish this? I understand how to bridge to virtual networks together, but how to I make the linux virtual machine sit between them and force traffic to go across the transparent bridge? I would like to have something along the lines of: vmnet a various vms host-only network ---- inline linux box vmnet a boxes forced to go through here to get to the internet --- vmnet b network with internet access configured as either NAT or bridged -- internet I know that basically the linux box needs two virtual nics, one on vmnet a and vmnet b, but other than that, I don't know how to force all the traffic to go across the "transparent" bridging linux box on its way to the internet. Do vmnet a and b have to be the same ip network with the same default route? does vmnet a not have a default route and vmnet b have a default route? I've read in vmware forums that on the linux host you need to change permissions on the vmnet files for promiscuous mode? is this true? how do you configure this scenario on a windows box?

  • iPhoto & iPhone Album order is different

    - by Ben Robinson
    I can't seem to find any answers to this, I have around 100 albums in iPhoto on my Mac, they are all synced to my iPhone, but on the phone they are just being displayed in a seeming random order. I have removed all the photos from the phone and started again, but they go back in the same order. In iPhoto the albums are actually in alphabetical order, have I've clicked the sort albums option, but this did nothing? Any ideas?

  • Screen flicker -> Severe System Slowdown?

    - by Adam Robinson
    I'm using a Dell D830 laptop, and over the last few weeks it's been developing a very irritating screen flicker problem that leads to the system slowing down almost to the point of unusability. At seemingly random times (no commonality between how long the system has been running, what I was doing, what applications were open, etc.) my screen (I use two external LCD's with the laptop closed in a dock) flickers for a moment, then the system becomes incredibly slow. The screen redraws painfully slowly--almost like what you might expect to see with generic graphics drivers installed--and the entire system is maddeningly unresponsive. The only thing that seems to be able to correct the issue is a restart. I've checked the event logs and nothing out of the ordinary is there, and definitely nothing that's common to all of the events. I'm running XP Pro SP2. Any ideas?

  • Which home automation technology to choose? x10 zwave e.t.c. in UK [closed]

    - by Stewart Robinson
    I work away most of the week and have to leave my house empty. I would like to have home automation monitor and control my house. Naturally I want to be a bit of a geek and do some of it myself so I've researched stuff like x10, zwave, cbus e.t.c. but I want opinions on which I should use in my house. I have a Linux box that could be used to actually do controlling if needed. So which technology and why?

  • Reconfiguring PHP with OpenSSL Extension on CentOS

    - by Evan
    Hi Guys - Long time browser, first time poster! I have a CentOS Dedicated server running just fine. I'm trying to reconfigure PHP to include the OpenSSL extensions so I can use some of the Youtube API's. I installed OpenSSL with yum, so it's in place on the server. I'm just now having trouble getting PHP to use it as an extension. I got the latest PHP tarball, untarred, set my configure string (./configure) using the proper parameter for openssl (--with-openssl=/usr) and it checked out just fine. I ran Make, then Make Install. I am getting hung up here. After it makes the PEAR config file it seems to quit. I guess I'm not sure, but it seems like there is a LOT more that should be happening. Here is a screenshot: http://www.evanfell.com/screencaps/6iamks.png Restarting apache shows no change to the PHP running on the server. Is there are PEAR issue killing the Install process? Or is there an other issue? Thanks In Advance. Happy to clarify and provide more info.
